Title: Detector for entering vehicle
Inventor: KOYAMA SATOSHI
IPC: G08G1/017
Filed: 1978-05-22
Abstract: PURPOSE: To miniaturize a device, and also to give an alarm on detecting easily an entering vehicle from a distance place by detecting whether or not light from an infrared-ray transmitter is reflected.  
     CONSTITUTION: Infrared rays from a transmitter (light emitting diode) are focused into nearly-parallel rays, which lighten "no entry" incication panel 2. Reflecting plates 5, provided on "no enty" indication plates 2, are arranged at an interval of width of approximate 3m on a lane where "no entry" should be indicated and if a recklwss driving vehicle enters, they can change in position or fall down, thereby preventing reflected waves from striking photo detector 4. Even if the reckless drivung vehicle cuts off infrared rays, no light strikes photo detecot 4. In this case, it is detected that the light is cut off to give an alarm, so that workers during their operations can know that the vehicle has entered.

Filed: 1980-05-07
Abstract: PURPOSE:To limit the harmonic overcurrent generated at the time of charging rise in a power source by connecting a parallel resonance circuit of a capacitor and an inductance in series with the capacitive reactance for limiting an overcurrent. CONSTITUTION:Parallel resonance circuits 16-20 of capacitors 14 and inductors 15 are connected to an overcurrent limiting capacitor 10. The circuits 16-20 have resonance frequency higher than the frequency of an AC power source 9 and different from each other, exhibits high impedance against the resonance frequency and also exhibits low impedance against the other frequencies. Accordingly, harmonic components generated due to the distortion of the waveform at the time of charging voltage rise are suppressed by the circuits 16-20 set to have high impedance against the high frequency. When the interval of the resonance frequency of the resonance circuit is set as narrow as possible to increase the frequency, its effect can be further increased.

Title: Magnet driving circuit
Inventor: MASAKI HIDEO
IPC: B41J29/38
Filed: 1985-03-26
Abstract: PURPOSE:To form a simple circuit configuration composed of markedly small number of parts; thereby, to ensure to prevent malfunction by providing a noise suppression circuit which is made non-conductive in the case of on/off operations of the power supply, and blocking noises coming out from output ports in an interface circuit. CONSTITUTION:Common signal outputs delivered from the output ports 2-4 are directly fed to each of the interface circuits 35-37 without any intermediate circuit such as open collector ICs. Each interface circuit composed of one transistor and one resistor alone is connected to a noise suppression circuit 38 and, beyond this, to an initial signal generating circuit 13. At the time of noise generation or on/off operations of the power supply, initial signal (a) comes to L level, and accordingly the transistor Q40 of the circuit 38 is on the off condition. The emitter of the transistor Q11 is open as the circuit 38 is non-conductive, and, therefore, noise pulses accompanying signal (c) are blocked by an interface circuit 35, resulting in no noise input to the CR motor 24. The same thing can be said of the LF motor 25 and the printing head 26.
