Title: Servo circuit
Inventor: SASAMURA KOHEI
IPC: G11B15/467
Filed: 1984-11-02
Abstract: PURPOSE:To control the traveling of a recording medium medium after recording accurately in a short time by sampling a playback signal at previously set time intervals and controlling the time constant of a tracking adjusting device on the basis of sampled data. CONSTITUTION:A signal to be frequency-modulated which is reproduced from the recording medium after recording is converted into a specific signal, which is supplied to a sampling means 15 through an input terminal 14 and sampled at previously set time intervals. A decision means 16 decides which of sampled data from the means 15 and the last sampled data is larger, or calculates the mean value of plural sampled data and decide on large/small relation between means values of plural sampled data. A control signal generating circuit 17 generates a control signal which varies the time constant of the tracking adjusting device 18 on the basis of the decision result of the means 16 so that the envelope level of the playback frequency-modulated wave signal is maximum, and then supplies the control signal to the adjusting device 18. The adjusting device 18 varies the traveling speed of the recording medium after recording.

Title: Controller of air conditioner provided with refrigerant heater
Inventor: NISHIMOTO TOSHIHIKO
IPC: F25B13/00
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of the reliability of a compressor which is caused when a refrigerant is overheated during a residual heat expelling operation after stoppage of combustion, and decomposed in an air conditioner provided with a refrigerant heater. SOLUTION: In case that a compressor is stopped during carrying out a residual heat expelling operation and a compressor delay operation for protecting appliances, the operation of a combustion air supply blower is stopped simultaneously with stoppage of the compressor, thus stopping the residual heat expelling operation. Due to such a construction, the reliability of the compressor is ensured by preventing a phenomenon that the temperature of a heat exchanger of a refrigerant heater is elevated by an exhaust heat generated by the residual heat expelling operation and the refrigerant is overheated and decomposed.

Title: Optical power control circuit for semiconductor light emitting element
Inventor: TSUNODA YOSHIYUKI
IPC: G11B7/125
Filed: 1989-09-07
Abstract: PURPOSE:To eliminate the influence of a high frequency signal and to enable stable writing by superimposing a high frequency current to the driving current of a semiconductor light emitting element during a read mode period and prohibiting the high frequency current to be superimposed during a write mode period. CONSTITUTION:The high frequency current higher than 100MHz generated from a high frequency oscillator 12 is supplied through a switch SW2 to an adder 9 and the switch is normally in a ON state and turned off in response to a write gate pulse generated in a write data block. In such a way, the high frequency current is superimposed to the driving current of the semiconductor light emitting element only in the read mode period and the high frequency current is prohibited from superimposition during the write mode period. Thus, the influence of the high frequency signal to write data is eliminated and the data can be stably written.

IPC: G01N21/00
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a photoacoustic gas sensor suitable for measuring the concentration of different gases containing an explosive gas. SOLUTION: A tubular sensor body 1 comprises a tubular measuring cell 13 having longitudinal axis extending vertically to the longitudinal axis of tubular sensor body 1. Consequently, the length of measuring cell 13 can be varied depending on a desired sensitivity and range of measurement without varying the outside dimensions of sensor body 1. A light source 5 is disposed such that the measuring cell 13 is irradiated with light but a film 2 is not irradiated and thereby no disturbance signal is generated. The gas sensor is made explosion-proof by enclosing the light source 5 and a photodiode for monitoring the light source 5 tightly from the environment. Function of a microphone, light source 5 and photodiode is monitored by analyzing a background signal.

Title: Operating method of portable transmitter for controlling of function of vehicle
Inventor: MARUTEIN RINTOMAIERU
IPC: H04B10/114
Filed: 1992-07-17
Abstract: PURPOSE: To make the operation of a simple closing device possible only in a relatively narrow space around a vehicle by radiating the output signal for control of a driving device in a short range with smaller output power than that of the output signal for control of a locking device. CONSTITUTION: When the progress of a signal is invariable with respect to a pulse train, the amplitude of the pulse of a maintained component A becomes a remarkably small value, for example, 50% of the amplitude of a signal component C. Therefore, the receivable output power and the range of a portable transmitter for a simple function (KB) become remarkably smaller as compared with the relatively long range for a locking function (ZV) and a burglarproof function (EDW). Therefore, the transmitter having two transmission keys can utilize the full output power or the full range by using the key of the signal component C or reduced output power by using the key of the maintained component A.
