Abstract
A blank oscillator 300′ is prepared for each office, and control data is written into this blank oscillator 300′, thereby manufacturing an oscillator 300. Upon receiving an order from a user terminal 10, a business center server 100 selects the most suitable office for the delivery of the oscillator and sends the data to the office. A data writing apparatus 200 installed in this office generates control data based on the data, and writes the control data into the blank oscillator 300′, thereby manufacturing the oscillator 300.
Claims23
An order-receiving/manufacturing system for receiving an order for an oscillator and manufacturing the oscillator according to a specification required by a user, comprising:
- a business center server adapted to receive, via a network, order data including a desired oscillation frequency and user data including a destination of said oscillator for the user, and adapted to select, among control-data writing apparatuses installed in a plurality of places, the control-data writing apparatus installed in the place most suitable for receiving the order for said oscillator based on the order data or the user data, and adapted to said order data and said user data to the selected control-data wiring apparatus;
- and
- said control-data writing apparatus adapted to generate control data from the received order data for an oscillator which oscillates in accordance with the control data written into said oscillator, and adapted to write said control data into said oscillator.
A control method for an order-receiving/manufacturing system for receiving an order for an oscillator and manufacturing the oscillator according to a specification required by a user, said control method comprising:
- a step of receiving, via a network, order data including a desired oscillation frequency and user data including a destination of said oscillator for the user;
- a step of selecting, among control-data writing apparatuses installed in a plurality of places, the control-data writing apparatus installed in the place most suitable for receiving the order for said oscillator based on said order data or said user data;
- a step of sending said order data and said user data to the selected control-data writing apparatus;
- and
- a step of generating control data from the received order data for an oscillator which oscillates in accordance with said control data written into said oscillator, and of writing said control data into said oscillator by said control-data writing apparatus.
A business center server for receiving, via a network, order data including a desired oscillation frequency and user data including a destination of an oscillator, said business center server comprising:
- office-management-data storage means for storing as office management data a management area assigned to each of a plurality of offices provided with a data-control writing apparatus for generating control data from the received order data for an oscillator which oscillates in accordance with said control data written into said oscillator, and for writing said control data into said oscillator by said control-data writing apparatus;
- office selecting means for selecting an office most suitable for receiving an order for said oscillator based on said user data and said office management data from a plurality of offices;
- and
- data sending means for sending said order data and said user data to the selected office.
A control-data writing apparatus installed in each office and provided with a function of receiving order data, for generating control data at least from said order data for an oscillator which oscillates in accordance with said control data written into said oscillator, and for writing said control data into said oscillator, said control-data writing apparatus being used for an oscillator which comprises:
- variable capacitor means for outputting a reference signal of a reference oscillation frequency obtained by adjusting a resonance frequency of a piezoelectric resonator;
- frequency control means for acquiring an output signal of an output frequency by dividing and/or multiplying the frequency of said reference signal;
- and
- a memory for storing control data of said variable capacitor means and said frequency control means, said control-data writing apparatus including:
