Apparatus for and method of controlling the opening and closing of channel for liquid

An apparatus for controlling the opening and closing of a channel for a liquid, comprising:

• heat transmitting means of a good heat conductivity type through which at least one channel for a liquid extends;
• at least one cooling and heating means having one heat absorbing and generating part secured to said heat transmitting means;
• heat exchanger means secured to another part of said at least one cooling and heating means;
• and
• controlling means for controlling said heat absorbing and generating part of said cooling and heating means to execute heat absorption or heat generation;
• said apparatus being arranged such that said channel is closed first by causing said controlling means to control said heat absorbing and generating part of said cooling and heating means which is closer to said heat transmitting means to execute said heat absorption and then by cooling said heat transmitting means to solidify said liquid in said channels in said heat transmitting means, and such that said channel is opened first by causing said controlling means to control the same heat absorbing and generating part to execute said heat generation and then by heating said heat transmitting means to melt said liquid solidified in said channels in said heat transmitting means.

An apparatus for controlling the opening and closing of channels for a liquid, comprising:

• heat transmitting means of a good heat conductivity type through which a plurality of channels extend in the same direction;
• at least one cooling and heating means having one heat absorbing and generating part secured to said heat transmitting means;
• heat exchanger means secured to another part of the at least one cooling and heating means spaced from the one heat absorbing and generating part;
• and
• controlling means for controlling said heat absorbing and generating part of said cooling and heating means to execute heat absorption or heat generation;
• said apparatus being arranged such that said channels are closed first by causing said controlling means to control said heat absorbing and generating part of said cooling and heating means which is closer to said heat transmitting means to execute said heat absorption and then by cooling said heat transmitting means to solidify said liquid in said channels in said heat transmitting means, and such that said channels are opened first by causing said controlling means to control the same heat absorbing and generating said heat transmitting means to melt said liquid solidified in said channels in said heat transmitting means.

An apparatus for controlling the opening and closing of a channel for a liquid, comprising:

• heat transmitting means through which at least one branch channel extends, said branch channel branching from at least one main channel for said liquid;
• at least one cooling and heating means having one heat absorbing and generating part secured to said heat transmitting means;
• heat exchanger means secured to another part of said at least one cooling and heating means;
• and
• controlling means for controlling said heat absorbing and generating part of said cooling and heating means to execute heat absorption or heat generation;
• said apparatus being arranged such that said channels are closed first by causing said controlling means to control said heat absorbing and generating part of said cooling and heating means which is closer to said heat transmitting means to execute said heat absorption and then by cooling said heat transmitting means to solidify said liquid in said channels in said heat transmitting means, and such that said channels are opened first by causing said controlling means to control the same heat absorbing and generating part to execute said heat generation and then by heating said heat transmitting means to melt said liquid solidified in said channels in said heat transmitting means.

• a plurality of heat transmitting means through each of which a branch channel branching from said channel for said liquid extends;
• cooling and heating means having one heat absorbing and generating part secured to at least one of said heat transmitting means and another heat absorbing and generating part secured to the remaining heat transmitting means;
• and
• controlling means for controlling said heat absorbing and generating part of said cooling and heating means to execute heat absorption or heat generation;
• said apparatus being arranged such that said channel is closed first by causing said controlling means to control said heat absorbing and generating part of said cooling and heating means which is closer to said heat transmitting means to execute said heat absorption and then by cooling said heat transmitting means to solidify said liquid in said branch channel in said heat transmitting means, said channel being simultaneously opened first by causing said controlling means to control the other heat absorbing and generating part to execute said heat generation and then by heating said other heat transmitting means to melt said liquid solidified in said channel in said heat transmitting means.
