Title: Heat ray type human body detector
Inventor: IKEGAWA TOSHIO
IPC: G01S7/48
Filed: 1990-08-28
Abstract: PURPOSE:To obtain a detector capable of reconciling the prevention of wrong information and rapid information by outputting an alarm at every one count capable of obtaining the comparison output based on the output of a sensor part after outputting an alarm at the point of time reaching a predetermined count value. CONSTITUTION:For example, in the case of a heat ray type human body detector of a three-count system, an alarm is outputted from a count circuit 18 at the point of time when the pulse output from a comparison circuit 16 based on the output of a sensor part 10 reaches three counts. On and after three counts, at each time when the pulse output from the comparison circuit 16 is obtained based on the output of the sensor part 10, that is, at every one count, an alarm is outputted and detection sensitivity can be raised apparently. Therefore, wrong information preventing function due to a three-count system functions effectively up to the first output of an alarm and, after an alarm is outputted at the point of time reaching three counts, an alarm is outputted at every one count to make rapid information possible and the state of the spot after information is once automatically performed can be easily grasped on the side of a monitor center.

Title: Ground-fault section detector
Inventor: KUMEGAWA HIROSHI
IPC: H02H7/26
Filed: 1992-08-25
Abstract: PURPOSE:To make it possible to detect a ground-fault section without using a voltage sensor, by forming a reference phase according to a synchronizing pulse signal transmitted from a key station to a terminal station, and comparing a phase of zero-phase current with the reference phase to judge a ground-fault section. CONSTITUTION:Each terminal station (7a1, 7a2,..., 7b1, 7b2,...) generates a reference phase according to a synchronous pulse signal transmitted from a key station 2 and judge a ground-fault direction by comparing a phase of zero-phase current with the reference phase. Then, the terminal station transmits the result to the key station 2. On the basis of the data about the ground-fault direction transmitted from these terminal stations, the key station judges a ground-fault section. In this way, the ground-fault section can be detected without measuring a zero-phase voltage, i.e., without using a voltage sensor.

Filed: 1990-08-27
Abstract: PURPOSE:To make construction easier by a method in which a coil spring turning circumferentially is provided to the periphery of a hollow drive shaft having an excavating blade and a liquid-discharging hole on its tip, and a stirring blade is projectionally provided to the tip of the coil spring. CONSTITUTION:While jetting cement milk from the tip hole 7 of a hollow drive shaft 3, the shaft 3 is turned with high torque at a low speed to excavate the ground by an excavating blade 6. The cement milk is mixed by a stirring blade 17 set on the tip of the coil spring 14, and when the pit reaches the hard ground, the shaft 3 and the spring 14 are operated while turning the blades 16 and 17 to form a solid column under the ground. By turning the spring 14 normally and oppositely, the spring 14 is displaced to the diameter-expanding or contracting direction to impinge on an adhered object 20 to separate it. The integration of the shaft 3 and the spring 14 can thus be prevented, making construction work easier.

Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To simplify the construction and the assembling method of an optical semiconductor device, to reduce the time required to assemble it, to improve the productivity and to reduce the cost by conducting the adjustment of the transmissive polarization plane direction of an optical isolator when fixing the isolator to a fixed member. SOLUTION: A lens 22 and an optical isolator 23 are beforehand fixed to a void section 33a of a fixed member 33 before it is assembled into the inside a housing 28. The adjustment of the polarization plane direction of the isolator 23 is conducted by placing a laser chip in the vicinity of the focusing position of the lens 22 and fixing the isolator 23 while operating the laser chip, for example. After rotating the isolator 23 to its optimum position, fix the member 33 to the isolator 23 by a YAG laser welding, for example. Thus, the transmissive polarization plane direction of the isolator 23 and the bottom surface of the member 33 are made parallel to each other. Thus, the workability is greatly improved because the work is conducted outside the housing 28 prior to the assembling of the parts into the housing 28.

Title: Test device for multiconductor cable
Inventor: MIMOTOSUGA KOUICHI
IPC: G01R31/02
Filed: 1988-09-12
Abstract: PURPOSE:To automatically confirm the twisted state of a twisted pair by inputting a signal to the twisted pair from a differential driver and monitoring the electric current induced in another twisted pair by means of a differential receiver. CONSTITUTION:An oscillator 1 outputs a signal to a twisted pair in a cable 7 to be tested through one differential driver 3 selected by a driver/receiver switching circuit 2 and another driver 3 is kept in a high-impedance state. When the twisted pair to which the signal is outputted is properly wired, the signal is only transmitted to the differential receiver 4 paired with the driver 3 outputting the signal, but, when the wiring is not proper, two or more receivers operate. Therefore, when a signal decision circuit 5 takes the AND of the OR of outputs of all receivers which are not connected with the driver and the output of the receiver paired with the driver, the propriety of the wiring or the twisted pair connected with the driver can be decided.
