Filed: 1985-05-08
Abstract: PURPOSE:To prevent engine stall by correcting the fuel injection quantity to reduction and preventing the excessive concentration of the mixed gas by the operation of a fuel increase logic on start, when the engine revolution speed reduces when a car starts.

Title: Transmission circuit
Inventor: YAMADA KUNIHIRO
IPC: H03K17/78
Filed: 1986-04-24
Abstract: PURPOSE:To reduce the constraint of a data pattern with a small amount of materials, by sending out the balanced output of a driver to a receiver by a stranded pair cable, at a transmission side, inputting the output of a detector to a decision circuit, and outputting a carrier detection signal when a positive or negative current is detected at the decision circuit by the detector, at a reception side. CONSTITUTION:Since the output of a driver 1 goes to high impedance when a transmission request signal RTS is a logic 0, no current is permitted to flow between I1 and I2, and the output terminals P and N of a detector 2 are logics 0. Therefore, a carrier detection signal CD that is the output of a decision circuit 3, goes to also the logic 0. Next, when the signal RTS is a logic 1, the output of the driver 1 goes to low impedance, then the current is permitted to flow between the I1 and I1 The direction of the current from the I1 to the I2, or from the I2 to the I1, is decided corresponding to 1 or 0 of a transmission data SD. Corresponding to the above, the output terminals P and N of the detector 2 go to N=0 when P=1, and N=1 when P=0. Therefore, it is possible to transmit each signal of (SD-RD), and (RTS-CD) without generating the constraint on the data pattern.

Title: Photosensor
Inventor: KANO SHUJI
IPC: G01V8/12
Filed: 1992-03-04
Abstract: PURPOSE:To provide a photosensor of small-sized structure and long lifetime by furnishing a light emission side power supply circuit with an element or circuit which modulates the frequency in differing from the turbulent light, and furnishing this element or circuit on its photo-receiving side with a band- pass filter which admits only passage of the frequency modulated in this manner. CONSTITUTION:A diode 11 is furnished in the power supply circuit of a lamp 1 while commercial AC 10 is used as power supply. A half-wave rectified voltage E' is impressed on this lamp 1, and the light emitted therefrom becomes a beam of light which was modulated with commercial AC frequency. If therefore a band-pass filter installed on the photo-receiving side is a one which admits only passage of the frequency band corresponding to the frequency of the emitted light, there is no influenced of turbulent light to allow accomplishment of a photosensor which is free from generation of error. Because a system to make photo-modulation electrically is incorporated, the resultant photo-sensor is constructed in small size, at a low cost, and with a long lifetime.
