Filed: 1991-10-15
Abstract: PURPOSE:To shorten an inspection time, to reduce an inspection cost, to reduce a parts cost, and to eliminate danger such as the whole system becomes non- operative. CONSTITUTION:Between a control part 1 and a transmitting part 2, a continuous transmission preventing circuit 3 is provided. For instance, it is assumed that the control part 1 constituted of a CPU, etc., runs away, and a transmission control signal holds the active. When continuous signals of an H level are inputted to the continuous transmission preventing circuit 3, a voltage of a B point becomes an attenuating waveform by a differentiating circuit constituted of a capacitor C1 and a resistance R1. Until the voltage of this B point becomes less than a threshold voltage VH of a buffer 4, an output voltage of the buffer 4 is active. That is, even if an A point holds an H level, as for an input to the transmitting part 2, when it exceeds a time constant determined by the capacitor C1 and the resistance R and the time T1 determined by the threshold value VH of the buffer 41 the transmitting part 2 does not execute a transmitting operation. This time T1 is set to two folds or below of the maximum value of a regular transmission time.

Title: Phase locked loop clock pulse generator
Inventor: SUZUKI NORIO
IPC: H03L7/08
Filed: 1987-10-23
Abstract: PURPOSE:To improve the response of synchronization control of a clock pulse by holding a control signal just before when a phase difference between a horizontal synchronizing signal and a clock pulse is larger than a prescribed range. CONSTITUTION:The phase of a horizontal synchronizing signal HS of a TV signal and that of a reference signal (d) being the frequency-division of the clock pulse from the pulse generating circuit 7 are compared by a phase comparator 3 and its output controls the oscillating frequency of the voltage controlled oscillator 6. When the frequency of the clock pulse rises and the phase difference with the signal HS exceeds a prescribed range, an output is caused in a NAND gate 9, a FF circuit 10 is set and a holding circuit 4 holds the control signal just before. Then the oscillated frequency of the oscillator 6 is decreased by a negative control signal and when the frequency reaches a prescribed range, the gate 8 is outputted to release the holding state of the circuit 4. Thus, the response of the synchronizing control of the clock pulse is improved.

Abstract: PURPOSE:To make stable mass production with good reproducibility by successively effecting particle formation reaction in a specified direction to substantially prevent mingling of the reaction solns. in plural stages of batch wise medium volume reaction vessels disposed in series with each other. CONSTITUTION:The particle formation reaction is effected successively in the specified direction in such a manner that the reaction solns. in plural stages of the batch wise medium volume reaction vessels 2a, 2b, 2c disposed in series do not substantially mix with each other.

Title: Device for transmitting high differential pressure
Inventor: HOSHINO YUKIO
IPC: G01L13/06
Filed: 1993-10-26
Abstract: PURPOSE:To measure stably by enduring an excessively large differential pressure from the high pressure side with the withstanding pressure, restricting a displacement of a center diaphragm to the low pressure side with a casing, and shifting the center diaphragm only when a differential pressure from the low pressure side to the high pressure side is applied. CONSTITUTION:When a differential pressure of PH>PL is impressed, the differential pressure is transmitted to a pressure-sensitive element 1 via pressure-receiving diaphragms 3, 4 and sealed liquids 10, 11. At this time, although the differential pressure is impressed to a center diaphragm 2 as well, an excessively large differential pressure from the high pressure side is coped with by the element 1 showing a larger pressure resistance to the high pressure side. On the other hand, when a differential pressure of PL>PH is impressed, that is, a pressure is applied from the low-pressure side, the differential pressure is transmitted to the element 1 and diaphragm 2, but, to a too large differential pressure, the low-pressure side pressure- receiving diaphragm 4 is seated on a casing 5 at a pressure lower than the withstanding pressure of the low-pressure side of the element 1 to prevent the element 1 from receiving too large differential pressure of the withstanding pressure of the element 1 or higher. Accordingly, the transmitter is protected against an excessively large differential pressure resulting from a pressure change. Moreover, it is prevented that a bending stress of not smaller than at a yield point is applied to the diaphragm 2, too.
