Abstract

To facilitate the manufacture of an accurate receiver, a piezoelectric device manufacturer determines characteristic data, such as an approximate expression representative of a temperature characteristic of piezoelectric device and coefficients of the approximate expression, and stores it to a memory of a manufacturer'"'"'s computer corresponding to a serial number of each piezoelectric device. The piezoelectric device manufacturer, ships a piezoelectric device to a vendor 90, transfers the characteristic data of the piezoelectric device to the vendor server 92 through a communication network 76. The client 94a, when the purchased piezoelectric device is mounted on an electronic appliance, reads out a serial number and inputs it to the client'"'"'s computer. The client'"'"'s computer acquires the characteristic data of the piezoelectric device corresponding to the serial number from the vendor server through the communication network, and writes it to a memory of the electronic appliance.

Claims

1. A method to manufacture a receiver incorporating a piezoelectric device, comprising:

storing characteristic data of a plurality of piezoelectric devices in a server, corresponding to identifying markers associated with each piezoelectric device; and

reading the identifying marker when the piezoelectric device is assembled in a receiver, and receiving the corresponding characteristic data from the server through a communication network depending upon a read-out identifying marker and writing the characteristic data in a storage section of the receiver.

3. The method to manufacture a receiver according to claim 1, the characteristic data being acquired during manufacturing the piezoelectric device.

4. The method to manufacture a receiver according to claim 1, the server being set up at a vendor for the piezoelectric device, the characteristic data being acquired during manufacturing the piezoelectric device and sent corresponding to the identifying marker to the server through the communication network.

5. A receiver characterized by being manufactured by a method to manufacture a receiver according to claim 1.

2. A method to manufacture a receiver incorporating a piezoelectric device, comprising:

acquiring a recording medium recording characteristic data of a plurality of piezoelectric devices corresponding to identifying markers associated with each piezoelectric device, together with the piezoelectric devices; and

reading the identifying marker when the piezoelectric device is assembled in a receiver, and reading the characteristic data corresponding to the read-out identifying marker from the recording medium and writing the characteristic data in a storage section of the receiver.
