Patent JP-H02218211-A (JP)
Title: Master flip flop circuit
Inventor: KUREIGU BII GURIINBAAGU
IPC: H03K3/013
Filed: 1989-12-20
Abstract: PURPOSE: To improve the reliability of a whole system by providing first and second cross-linked transistors which generate a desired output in response to an input signal, and a means connected with the outputs of the first and second transistors for preventing a semi-stable state present at the output from being propagated to a slave flip flop circuit. CONSTITUTION: Transistors 76 and 78 are added between the outputs of transistors 40 and 48 and resistance 100 and 102. The emitter of the transistor 76 is connected with the collector of the transistor 48 and the base of the transistor 78. The transistors 40 and 48 are both saturated, and the base is clamped to the same voltage level. The collectors of the transistors 40 and 48 are set in the same potential so that the generation of vibration at the both edges of the transistors 76 and 78 can be prevented, and the transistors 76 and 78 are held off. Thus, an output OUT1 and an output OUT2 can be maintained to be a constant value. When a noise is present in the bases of the transistors 40 and 48, the transistors 40 and 48 are clamped so that vibration can not be generated.

Title: Fm transmission device
Inventor: MIYAKE KIMITAKE
IPC: G11B20/06
Filed: 1989-12-19
Abstract: PURPOSE:To execute decision with few errors with simple constitution by deciding that there is a second carrier signal when the amplitude of a signal obtained by attenuating a prescribed frequency component from a demodulation output is equal to or under a prescribed value. CONSTITUTION:The demodulation output from an FM demodulator 20S is supplied to a nnad-pass filter 31 and a component in a demodulation frequency band and an unnecessary component related to the carrier signal are eliminated. Then, the output of the filter is converted into a DC voltage by a detector 32. When the voltage is equal to or under a reference voltage as the result that it is compared with the reference voltage by a comparator 33, it is decided that there is the second carrier signal. Then, the decision output is fetched to an output terminal 34. In such a way, it is decided that there is the second carrier signal by detecting the amplitude of the FM-modulated signal. Thus, by the simple constitution, the device does not receive an affect by the level change of a reproduced signal from a magnetic head 13. Besides, malfunction caused by the erroneous detection of an interferring wave is excellently prevented from occurring.

Title: Variable discharge high-pressure pump
Inventor: YAMAMOTO YOSHIHISA
IPC: F04B9/04
Filed: 1988-12-28
Abstract: PURPOSE:To enable the prompt discharge of accurate, stable and most appropriate common rail pressure with low driving energy even under hard conditions such as a low-speed driving time by controlling the pressure applying/force-feeding starting time and discharge of fuel by means of an outer-open type solenoid valve. CONSTITUTION:A variable discharge high-pressure pump, as its cam speed reaches its peak in the first half of the rising stroke of a plunger, reaches a certain extent of cam acceleration already at a control starting time as well as the rise of the plunger is accelerated to be high in speed. Accordingly, the pressure in a pump chamber can be made high enough, in the short initial rising time of the plunger, to maintain a closed outer-open type solenoid valve in the closed state. As a result, although a valve closing designating time T0 is set short in order to enable the sufficient operation of the variable discharge high-pressure pump even at a high speed driving time, the pump pressure enough to maintain the closed state of the valve within the short valve closing designating time T0 can be ensured, so that force-feeding can be continued until the plunger reaches its top dead center even after the valve opening is authorized in a short time, and thus high-volume discharge can be ensured even at a low speed driving time.

Title: Gravimeter
Inventor: HARADA MANABU
IPC: G01N9/18
Filed: 1994-12-07
Abstract: PURPOSE: To extend the service life of a gravimeter by utilizing current for returning a mobile piece to a zero-point position as the specific gravity value of a liquid and hence blocking a lower through-hole of the body of the gravimeter with a soft gas- penetration-preventing sheet and preventing internal fracture due to a corrosive gas. CONSTITUTION: When the specific gravity of a liquid 1 decreases, a bob 2 sinks, thus causing a permanent magnet 4 (4A and 4B) which is a mobile piece to descend from the zero point 7 against the elastic force of a leaf spring 5 and causing difference in the quantity of emitted light of photoelectric conversion elements 9A and 9B constituting a zero point detector 26. Therefore, by allowing current to flow to a coil 3 from a servo amplification circuit 17 according to the output signal, the magnet 4 and a light source 8 are returned to the zero point 7.  Since the current flowing to the coil 3 is proportional to the thrust by which the coil 3 returns the magnet 4 and the light source 8 and the forces are balanced at a point P at the time of equilibrium, the mass (specific gravity of the liquid 1) of the bob 2 in the liquid can be accurately detected even if a string is passed through a soft gas-penetration-preventing sheet 18. Also, since the through hole is closed by the sheet 18, a corrosive gas can be prevented from entering a gravimeter body 11-1.

Abstract: PROBLEM TO BE SOLVED: To improve performance and reduce working costs by reducing stress generated in a rim in the bottom of a flexible external gear and in an inner ring rolling surface of a wave generator, in a deflection meshing gear device. SOLUTION: The fundaments of the flexible external gear and a stiffness internal gear are a spur gear, and the number of gear of the flexible external gear is reduced smaller than that of the stiffness internal gear by 2n (n is a positive integer).

Title: Printed matter evaluation method and its device
Inventor: OTA TOSHIO
IPC: G01N21/88
Filed: 1990-11-30
Abstract: PURPOSE:To decide a defective location of a printer matter without causing evaluation error by lowering evaluation accuracy in the longitudinal direction when the movement of a paper in the circumferential direction is large by a method wherein a moving quantity of a printing paper in the cylinder circumferential direction is previously measured, and a suitable evaluation level is automatically set. CONSTITUTION:Image data is fetched for each printing paper, and each picture element of the image data between a sample paper and the printing paper is compared, and when NG data is found, a tape is inserted in the defective printing paper by a tape inserter. Then, a solid patch 31 is printed by a color with high concentration at a butt side 30b, which is outside of a pattern range, on a printing paper 30, and a distance from a gripper end 30a to the solid patch 31 on the printing paper 30 is compared. By comparing the distance from the gripper end 30a of the printing paper 30 for each printing paper, unevenness of printing paper movement in the vertical direction is obtained. When the obtained unevenness quantity is not lower than the length of 1 picture element, evaluation accuracy in the longitudinal direction is lowered, and decision is performed without causing evaluation error. Also, when the unevenness quantity is less than the length of 1 picture element, the evaluation accuracy is improved so that an appropriate evaluation level in response to the unevenness quantity is set.
