Title: Airtightness inspection apparatus for tank
Inventor: TANAKA SHOICHI
IPC: G01M3/04
Filed: 1987-04-06
Abstract: PURPOSE:To make the title apparatus simple and economical without using a water tank and to eliminate an inspection error, by locking a tank to be inspected to introduce air into the tank under pressure and inspecting airtightness on the basis of leak sound by an ultrasonic microphone before unlocking the tank. CONSTITUTION:The fuel tank T for a car is set to a working table 1 and the lock pin 3a of an electromagnetic type lock operating machine 3 is inserted in a lock hole to lock the tank T. Subsequently, compressed air of about 0.1kg/cm<2> is supplied to the tank T by a pump 7 and an airtightness test is performed on the basis of the leak sound in the vicinity of the mount part of the tank by an ultrasonic microphone 9M being a leak sensor. When the leak sound is generated, a buzzer and a rotating warning light 18 are operated and, after the finish of the inspection, the tank is unlocked. A series of these operations are automatically performed through a control box 12. As a result, since a water tank (water) is not used, inspection is made simple and economical and an inspection error can be eliminated.

Abstract: PURPOSE: To increase a HC amount meeting operating condition of an engine in an exhaust emission control system simply. CONSTITUTION: In a feed pump for supplying fuel to a fuel injection pump 1 by pressurizing fuel in a comparatively low pressure, the operating condition of an internal combustion engine, for example, it is noticed that feed pressure of fuel whose volume is changed according to rotating speed is generated. A part of fuel of feed pressure is taken out to a HC feed line 2 by a HC taking- out part 2a, pressure is regulated by a throttle 3, and it is supplied to a HC feed device 5 arranged upstream from an exhaust emission control system (for example, a catalyst). Exhaust purifying action is assisted as amount increasing HC by fuel which is mixed with exhaust gas and supplied to the exhaust emission control system 6.  Since the amount of fuel supplied as HC is automatically regulated to a volume meeting operating condition of an engine, HC is supplied without the shortage even if complex means for regulating a HC feed amount especially is not used.

Title: Magneto-optical recording medium
Inventor: YAMAMOTO MANABU
IPC: G11B11/105
Filed: 1987-04-06
Abstract: PURPOSE:To make the switching of the polarity of an external magnetic field unnecessary and to perform the rise of an erasing operation at high speed, by arranging a second perpendicularly magnetized film having the Curie temperature higher than that of a first perpendicularly magnetized film and magnetized uniformly at a part adjacently to the first perpendicularly magnetized film. CONSTITUTION:The second perpendicularly magnetized film 7 is formed adjacently to the first perpendicularly magnetized film 2 that is an information recording carrier. The second perpendicularly magnetized film 7 is magnetized uniformly, and always supplies a perpendicular magnetic field H7 to a magneto-optical recording medium. The recording of information is performed by lowering a coercive force Hc due to the temperature rise of the medium by photoirradiation, and arranging it in a direction of an applied magnetic field Hw'. At the time of erasure, the inversion of magnetization is performed by the magnetic field H7 supplied from the second perpendicularly magnetized film 7 to the first perpendicularly magnetized film 2 by applying no Hw', and rising the temperature of the medium larger than the Curie temperature by the photoirradiation. In such a way, it is possible to make the switching of the polarity of the external magnetic field at the time of erasure, and to perform the rise of the erasing operation at high speed.

Title: Variable delay circuit
Inventor: YAMANAKA NAOAKI
IPC: H03K5/13
Filed: 1985-04-19
Abstract: PURPOSE:To eliminate the deterioration and attenuation of a waveform and to control the fine quantity of attenuation by selecting a signal passed through an optional number of stages of gates composed of an active element, and thus determining the quantity of attenuation freely and controlling the quantity of delay of every gate. CONSTITUTION:An input pulse signal inputted from an input highway 1 is delayed by an integral multiple of the delay time (TPD) of one gate when propagated in gates 3-1-3-n. A desired delay output is selected by a selector 4 on the basis of delay quantity selection signals 5-1-5-3 and sent out to a delay output highway 2. the gate delay time (TPD ) of the gates 3-1-3-n varies with the value of a current flowing through their TRs. This is utilized to vary voltages at fine delay adjustment terminals 6-1-6-1, thereby adjusting finely the gate delay time (TPD) of each gate. Consequently, size reduction (IC and LSI implementation ) is carried out and neither the deterioration nor the attenuation of the waveform results.

Filed: 1987-04-06
Abstract: PURPOSE:To always execute the stable reproduction of color picture by providing a prescribed number varying means in an integration circuit and minimizing the time constant of the integration circuit only in a horizontal fly-back line period and its specified delay period. CONSTITUTION:A blanking pulse P is fetched to pass through a delay circuit 15 and made to start a switch 17 through an amplifier 16 in a horizontal fly- back line period and about scanning beginning spot, namely during the period T1+T2. During that period, the switch 17 is in an ON-state and the time constant of the integration circuit 12 is decided by the parallel composed resistances consisting of a resistance R1 and a resistance R2 and a capacitor C1. In a horizontal scanning period T3 after that, the blanking pulse P is not added, so that the switch 17 is in an OFF-state and the time constant of the integration circuit 12 is decided by the resistance R1 and the capacitor C1. Thus, the time constant of the integration circuit 12 at the time when the switch 17 is OFF is larger than that of the integration circuit 12 at the time when the switch 17 is ON but the disorder of frequency caused by noises becomes small and the switching of colors is stabilized.
