Abstract
A feed controlling apparatus that controls feeding of plural minute objects that flow along a channel of a fluid, and receive a predetermined process at a predetermined position, includes a detector that detects whether there is the object at the predetermined position, and a controller that controls feeding of the object to be supplied to the predetermined position based on a detection result by the detector.
Claims13
A feed controlling apparatus that controls feeding of plural minute objects that flow along a channel of a fluid, and receive a predetermined process at a predetermined position, said feed controlling apparatus comprising:
- a detector that detects whether there is the object at the predetermined position;
- and
- a controller that controls feeding of the object to be supplied to the predetermined position based on a detection result by said detector.
A feed controlling apparatus that controls feeding of plural minute objects that have received a predetermined process at a predetermined position and flow along a channel of a fluid, said feed controlling apparatus comprising:
- a detector that detects a result of the predetermined process;
- and
- a controller that determines, based on a detection result by said detector, a feed path through which a processed object is to flow from the predetermined position.
A feed controlling apparatus that controls feeding of plural minute objects, and receive a predetermined process at a predetermined position, said feed controlling apparatus comprising:
- a channel that feeds the objects one by one to the predetermined position;
- a gate member that varies between a first state that allows the object to be fed along said channel, and a second state that prevents the object from being fed along said channel;
- and
- a controller that controls said gate member so that said controller varies said gate member to the first state when determining that there is no object at the predetermined position, and said gate member to the second state when determining that there is the object at the predetermined position.
A feed controlling apparatus that controls feeding of plural minute objects that have received a predetermined process at a predetermined position, said feed controlling apparatus comprising:
- a channel, connected to a recovery part and a disposal part, which feeds the objects one by one from the predetermined position;
- a gate member that varies between a first state that allows the object to be fed to the recovery part along said channel, and a second state that allows the object to be fed to the disposal part along said channel;
- and
- a controller that controls said gate member so that said controller varies said gate member to the first state when determining that the process has succeeded, and said gate member to the second state when determining that the process has failed.
A feed controlling apparatus that controls feeding of plural cells to a recovery part from a predetermined position at which a predetermined material is injected into each cell in a cell suspension by using a capillary, said feed controlling apparatus comprising:
- a storage that stores injected cells;
- and
- a controller that simultaneously supplies a predetermined amount of injected cells to the recovery part when determining that the predetermined amount of injected cells are stored in said storage.
A feed controlling method that utilizes two or more gates located at an upstream side to a predetermined position along a channel of a fluid, and controls feeding of plural minute objects that flow the channel and receives a predetermined process at the predetermined position by a processing unit, said feed controlling method comprising:
- a first step of determining whether the object comes down stream close to the predetermined position;
- a second step of opening a first gate that is located upstream among the gates, and of allowing the object to pass the first gate;
- a third step of determining whether the object is filled in a space between the gates;
- a fourth step of closing the first gate and of blocking a flow of the objects, when said third step determines that the object is filled in the space;
- a fifth step of determining whether the predetermined process by the processing unit is available;
- and
- a sixth step of opening a second gate that is located downstream among the gates, and of allowing the object to pass the second gate, when said fifth step determines that the predetermined process is available.
A feed controlling method that utilizes two or more gates located at an upstream side to a predetermined position along a channel of a fluid, and controls feeding of plural minute objects that flow the channel and receives a predetermined process at the predetermined position by a processing unit, said feed controlling method comprising:
- a first step of closing the most downstream gate and of opening gates other than the most downstream gate;
- a second step of sequentially closing the gates opened by said first step so that each space between two adjacent gates is sequentially filled with the object in order from a downstream side;
- a third step of determining whether each of all the spaces among the gates is filled with the object;
- a fourth step of determining whether the predetermined process by the processing unit is available when said third step determines that each of all the spaces among the gates is filled with the object;
- and
- a fifth step of sequentially opening the gates in order from a downstream side and of allowing the objects to pass the gates that have been opened, when said fourth step determines that the predetermined process is available.
A feed controlling method that utilizes two or more gates located at an upstream side to a predetermined position along a channel of a fluid, and controls feeding of plural minute objects that flow the channel and have received a predetermined process at the predetermined position by a processing unit, said feed controlling method comprising:
- a first step of determining whether the predetermined process has succeeded or failed;
- a second step of opening one of the gates and of allowing the object to flow along a first feed path to a recovery part when said first step determines that the predetermined process has succeeded;
- and
- a third step of opening another of the gates and of allowing the object to flow along a second feed path to a disposal part when said first step determines that the predetermined process has failed.
A processing system comprising:
- an injector that automatically injects a predetermined material into plural minute objects that flow along a channel of a fluid, at a predetermined position by using a capillary;
- and
- a feed controlling apparatus that automatically controls feeding of the objects to the predetermined position based on whether the object is located at the predetermined position.
A processing system comprising:
- an injector that automatically injects a predetermined material into plural minute objects that flow along a channel of a fluid, at a predetermined position by using a capillary;
- and
- a feed controlling apparatus that determines a feed path for an injected object based on whether an injection by said injector has succeeded or failed.
