Title: Photoelectric converting circuit
Inventor: SHIMIZU HISAYOSHI
IPC: G01D5/26
Filed: 1979-05-25
Abstract: PURPOSE: To reduce the fluctuation of the photoelectric conversion signal to the fluctuation of the light volume, the aging and the deterioration of characteristics, by using the photo transistor with base for the photoelectric converting element and then applying the bias voltage to the base.  
     CONSTITUTION: When the light volume of lamp 1 decreases, the base current of photo transistor Q which is produced by the optical signal decreases. And the potential going to lower is compensated with increment of base current i b  supplied from the bias circuit, thus preventing the lowering of output voltage VA. On the contrary, the increment of the base current of transistor Q causes increase of the base voltage. As a result, current i b  supplied from the bias circuit decreases to prevent increase of voltage VA. In the same way, if the photoelectric converting characteristics of transistor Q changes along with the fluctuation of the base current due to the optical signal, the base current flows from the bias circuit to give correction to the fluctuation.

Title: Self-supporting type solenoid control device
IPC: G11B15/10
Filed: 1992-03-19
Abstract: PURPOSE:To exactly set fast forward mode or rewind mode by a least two or more times applying an attracting force releasing voltage near the prescribed timing which releases the attracting force of a self-supporting type solenoid. CONSTITUTION:When a pin P is located near P3, that is, near the prescribed timing where the attracting force is to be released, a voltage is applied for few times to make the attracting force to be zero. By this, an attracting force is generated in a trigger magnet, the pin P does not move from P3 to P5 when the attracting force is released and it moves along a cam surface 11 in the successive order of P4 P6 P7 by the pressing force of a spring. Due to a projecting section T3, an attracting force acts on the trigger magnet after that, the pin P leaves the cam surface 11 and moves to the position of P7. By the motion of the pin P above, a tape does not contact a magnetic head and a pinch roller, the tape moves at a high speed and a fast forward or a rewind mode are surely set.

Title: Liquid level detecting device
Inventor: KITAGAWA JIYUNJI
IPC: G01F23/26
Filed: 1982-04-16
Abstract: PURPOSE:To detect liquid shortage quickly, by forming a detecting capacitor comprising a pair of facing electrodes, wherein the gap at the lower part is broader than the upper part, at the lower end of a level gage pipe, which is inserted into an engine oil container and the like. CONSTITUTION:When the quantity of engine oil is few, the small gap between electrodes 101 and 102 is filled with air. Therefore the permittivity of the gap is 1.0. Therefore, the electrostatic capacity value of a detecting capacitor 110 in a resistor capacitor type oscillator of a detecting circuit 202 becomes smaller than the electrostatic capacity values of a capacitor 217. The operation of the oscillator at this time is similar to the operation of a ring oscillator, and oscillating frequency becomes high. The oscillated signal is inputted into a CL terminal of a binary counter 221. A high frequency pulse signal is generated at an output terminal Q7 of the seventh stage, and outputted to a terminal 12 through a transistor 222. Then the fact that the oscillating frequency is equal to or higher than a preset value is detected by a display part 300. Then a lamp is lit and the shortage of the engine oil is indicated.

Abstract: PURPOSE:To reduce power consumption by using a synchronization acquisition section to take synchronization between PN series of a modulation side and a demodulation side once, storing frequency information to a memory, stopping the synchronization acquisition section, selecting a memory with small power consumption and adjusting the oscillator. CONSTITUTION:A spread spectrum signal S is given to a local oscillator 3 and a mixer 5, in which the signal is converted into an intermediate frequency f1 and a multiplier 6 forms an inverse spread signal J and a data demodulation section demodulates it to obtain data D. Furthermore, a synchronization acquisition section 9 gives a frequency spectrum(FS) obtained from the signal J to a PN series generator 4 via a timing circuit 12 to synchronize the PN series of the modulation side and the demodulation side. Simultaneously a power supply controller 16 receiving the FS stores the FS to a memory 15 to stop the operation of the acquisition section 9 requiring much power consumption. Then the controller 16 gives the FS in the memory 165 requiring less power consumption to a correction circuit 13 to adjust the oscillator 3 and to set a frequency f1 to a center frequency of a BPF 10. Thus, the power consumption is reduced.
