Title: Detecting circuit for power supply voltage
Inventor: SATO KOICHI
IPC: G05F1/56
Filed: 1986-03-07
Abstract: PURPOSE:To prevent the malfunction of a load circuit by performing comparison between two reference voltage levels through a comparator and using this comparison output to drive a switching transistor. CONSTITUTION:The output V0 of a comparator 1 is set at a low level in case the power supply voltages VCC1 and VCC2 are normal and abnormal respectively (VB>VD). Thus a transistor TR Q4 is turned off and the voltage V1 is set at a high level to turn off a TR Q6. While the voltage VC is set less than a reference level when the voltages VCC1 and VCC2 are abnormal and normal respectively. Thus a TR Q2 and a TR Q3 are turned off and on together with the TR Q4 turned off respectively. A TR Q5 is turned on when the TR Q4 is turned off and the TR Q6 is turned off. Thus the actions of both load circuits L1 and L2 are cut off.

Filed: 1986-03-06
Abstract: PURPOSE:To reduce the size and weight of a device by providing tooth parts to the outside periphery of sector levers which are tape drawing-out means in tape loading operation. CONSTITUTION:This tape loading device is provided with the tooth parts 21a, 21b on the outside periphery of the sector levers 22a, 22b which are the tape drawing-out means in the tape loading operation. Driving power is thereby directly transmitted through sector gears 21a, 21b without via a sector spring 25 in the position where shaft holders 8, 10 of the tape drawing-out means contact a post stopper or in the position where said holders contact an erase head base 5 in the state of restoring the mounting state of a tape cassette. The sector levers 22a, 22b and the sector gears 21a, 21b are thus integral with each other and therefore the drawing out of the ape is smoothly executed without interference even if the load is increased by the contact of the shaft holders 8, 10 of the tape drawing-out means with the erase head base 5. The tape cassette loading state is thus surely restored.

Abstract: PURPOSE:To provide a robust and highly accurate speedometer which does not have any moving parts by providing ultrasonic transmitting-receiving parts at an equal spacing in the moving direction integrally with a moving object and receiving the random noise included in the reflected waves from the ground during running. CONSTITUTION:The receiving signals having been transmitted and received by ultrasonic transmitters-receivers 31 thru 38, 31' thru 38' as a moving object 1 moves in the arrow direction have been modulated by the random noise owing to the undulations of the ground 2. The receiving signals from the receivers 31' thru 38' are applied to modulators 41 thru 48 to become modulated signals which are then sent out to an adder-subtractor 50, by which the output signal f0' is obtained and this becomes the signal wherein the specific frequency component (N+1/2)v/d has been intensified. Here, v denotes the speed of the moving object and N the receiving part serial numbers and if their spacing d is suitably selected, the signal f00=v/2d of N=0 may be intensified, thus the speed v may be known by measuring the frequency f00. The object 1 is installed to the body of an automobile and its speed may be known from the signal f0, thus the speed to the ground may be obtained at high accuracy and the robust speedometer obtained.

Title: Strobing device
Inventor: SATO YUZURU
IPC: G02F1/13
Filed: 1986-03-07
Abstract: PURPOSE:To obtain a high speed strobing whose light emission duration is several microseconds or shorter, by providing a liquid crystal shutter using a ferroelectric liquid crystal behind a strobe light source and switching the liquid crystal shutter synchronously with light emission of the light source and shortening this switching time to a desired time. CONSTITUTION:A liquid crystal shutter 12 which is switched quickly is provided behind a strobe light source 11, and the liquid crystal shutter is switched synchronously with light emission of the light source. For example, if a ferroelectric liquid crystal HOBACPC is used to form a strobing device and the voltage applied to the liquid crystal shutter 12 is set to + or -30V, a duration t2 of light emitted from the strobing device is shortened up to a maximum of about 1.6sec regardless of a light emission time t1 of the light source because a response speed t3 of the liquid crystal shutter 12 is about 0.8musec. Since a response speed gammaof the liquid crystal shutter is inversely proportional to the applied electric crystal and the liquid crystal shutter can be switched more quickly according as the applied electric field or the spontaneous polarization is increased, the duration of light emission can be <=1musec.

Title: Particle-dispersion composite electroplating method
Inventor: KURAHASHI MOTOFUMI
IPC: C25D15/02
Filed: 1988-03-04
Abstract: PURPOSE:To improve the quality of a particle-dispersion composite plating by moving a particle-contg. plating soln. and a material to be plated in the same direction, and adjusting the moving velocity of the plating soln. and/or the material to accurately control the dispersion of particles. CONSTITUTION:A cold-rolling roll 2 for band steel is arranged in a plating bath 1, and an anode 3 is provided in the bath 1. The particle-contg. plating soln. 4 is supplied into the bath 1 from a nozzle 5 through a chute plate 6. The plating soln. 4 is discharged from an outlet 7 at the bottom of the bath 1, circulated, and again supplied to the bath 1. The roll 2 is plated while being rotated. The roll 2 is rotated in the same direction as the flow direction of the plating soln. 4, and hence the particles are uniformly dispersed in the thickness direction of the plating layer. As a result, the quality of the particle- dispersion composite plating can be improved. A ceramic such as VC and SiC can be exemplified as the material for the particles to be dispersed in the plating layer (see Table I).

Title: Internal combustion engine ignition device
Inventor: HINO TOSHIYUKI
IPC: F02P3/00
Filed: 1981-04-01
Abstract: PURPOSE:To enable an ignition device composed of a current breaking type combined with a capacity discharging type to prevent knocking and the like by impressing capacity discharging type output on an ignition plug earlier than a spark discharge from a current breaking type. CONSTITUTION:When an interrupter device 3 is closed, an exciting coil 15 is not turned on, a contact point 14 is opened and both a condenser 12 and a diode 5 are in OFF state, being cut off from an ignition plug 6. When the device 3 is opened, the exciting coil 15 is supplied with power from a direct current power source 1 through a primary coil of an ignition coil 2, the contact point 14 is closed and both the condenser 12 and the ignition plug 6 are connected. Since the interrupter device 3 is closed at T0 in an exhaust stroke and opened at T21 right before the regular ignition time T22, charging voltage Vc of the condenser 12 is temporarily cut off from the ignition plug 6 at T0, impressed again at T21, and then discharged through the ignition plug 6 at T22. Thus there is no discharge through the ignition plug 6 even if a required voltage 42 drops below Vc in the intake stroke, therefore, a knocking phenomenon due to an erroneous ignition during intake stroke is not generated.

Title: Internal gear pump in trochoidal engagement
Inventor: KOBASHI HARUHIKO
IPC: F04C2/10
Filed: 1985-03-13
Abstract: PURPOSE:To reduce a radial clearance as well as to prevent any leakage between both suction and discharge ports from occurring, by setting an eccentric value between an axial center of a support hole for an outer rotor of a trochoidal pump and another axial center of a bearing hole for an inner rotor smaller than a theoretical eccentric value. CONSTITUTION:An eccentric value between an axial center C1 of a cylindrical body 1 supporting an outer rotor 3 of a trochoidal pump and another axial center C2 of a bearing hole for a shaft 6 supporting an inner rotor 4 is being set to be smaller than a theoretical eccentric value between the axial center of the outer rotor and the axial center of the inner rotor. Therefore, even if both rotor axial centers are slightly slipped, a radial clearance S of the inner rotor 4 is not so much increased so that a quantity of the fluid leaked from a discharge port to an suction port via the radial clearance S is reducible.
