Title: Synthesizer receiver
Inventor: SATO KATSUYUKI
IPC: H04B1/16
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for inputing again a broadcasting station name by leaving data on a broadcasting station name for a preset channel selection key, when data on the reception frequency of the preset channel selection key has the same value as that prior to automatic presetting. SOLUTION: The frequency division ratio N of a variable frequency dividing circuit 22 is set to a minimum value 653 through a port 35, and the reception frequency is set to a lowest frequency of 76 MHz. When a broadcast of certain frequency is received during a scan, the frequency division ratio N and data on the broadcasting station name which are not updated by current automatic presetting remain. When the frequency division ratio N of a channel selection key to be preset has the same value as that prior to the automatic presetting, the data on the broadcasting station name is left as to the channel selection key. When the frequency has no variation prior to and after the automatic presetting, the broadcasting station is the same. Therefore, when the reception frequency (frequency division ratio N) is the same, by leaving the data on the broadcasting station name, the need for input operation again is eliminated.

A material to be permeated by the wave such as, for example, refractory brick 22 is used, and the wave generated from the antenna 15 is transmitted through the chamber 10. The wave passed through the flame in the chamber 10 is permeated by the ratio responsive to air fuel ratio, permeated by the brick 23 and received by a receiving antenna 17. An air fuel ratio controller 18 receives a transmission intensity signal 19 from the transmitter 14 and a reception intensity signal 20 from a receiver 16, obtains the ratio of the wave, and controls an air amount so that the ratio becomes minimum.

IPC: H01M8/06
Filed: 1988-11-11
Abstract: PURPOSE:To prevent catalysts for reforming from being oxidized, without the structure of the device becoming complicated, by providing a heating passage with an air blowing device capable of blowing a larger amount of air than the required amount of air blowed for operating a fuel cell, and providing means for controlling the air blowing device so that the amount of air blowed is decreased when the air blowing device is operated, whereas it is increased when the device is stopped and cooled. CONSTITUTION:A heating passage B which allows heated gas heated by a burner 9 to pass therethrough is provided with an air blowing device 15 capable of blowing a larger amount of air than the required amount of air blowed for operating a fuel cell 16, and controlling means C are provided for controlling the air blowing device 15 so that the amount of air blowed is decreased when the air blowing device 15 is operated, whereas it is increased when the device is stopped and cooled; i.e., a larger amount of air than the amount of air blowed during operation is forced to pass through the heating passage B, so that a catalyst layer 2 in a raw material passage A is forcibly cooled to enable the temperature of the catalyst layer 2 to be lowered less than its active temperature region. The catalyst can thus be cooled promptly and be preserved when the air blowing device is stopped, and therefore the reforming capability of the catalyst can be prevented from deteriorating without the structure of the device becoming complicated.
