Title: Assisting device for operating lever
Inventor: ARAKAWA HIDETOSHI
IPC: B62M25/04
Filed: 1988-06-30
Abstract: PURPOSE:To reduce the force necessary for a driver to operate an operating lever by providing a spring between a spot on the handle side near a rotation supporting axis of the operating lever and an end-part of the operating lever in order to connect the both in a freely rotatable manner, so that tension or compression is generated if the straight line, which connects both supporting points, deviates from the rotation supporting axis line. CONSTITUTION:A rotation supporting axis between an operation lever 3 and a bracket 4 of a handle part is provided to a base part of the operation lever 3, and an end of the bracket 4, which is located near this rotation supporting axis, is connected to an end of the operation lever 3 by a spring 7 in a freely rotatable manner. In this case, it is aimed that the compression generated becomes the largest when the center of rotation O is situated on a straight line T, which connects both supporting points R and S. When the amount of operation of the operation lever 3 is large, the supporting point R of the spring 7 on the operation lever 3 side moves. And, if a straight line T, which connects both supporting points of the spring 7, passes the rotation supporting axis, the rotating and pushing direction of the spring 7 is reversed. With this contrivance, only a difference between the reaction of the device itself and the spring load of the spring 7 is felt by a driver as the reaction from the device. In other words, the force necessary for the driver to operate the handle is reduced.

IPC: G01R31/26
Filed: 1985-07-24
Abstract: PURPOSE:To make it possible to more accurately obtain the boundary of the distribution region of good products within a semiconductor wafer by performing full number of inspections only for previously selected arrangement of the semiconductor elements vertically and horizontally arranged within the semiconductor wafer. CONSTITUTION:Arrangements of semiconductor elements l1-l4 equally separating the area of a semiconductor wafer 1 into 8 sections are selected, all the semiconductor elements on it are inspected, and the results of the inspection are recorded on each semiconductor element. According to the results of the inspection, for example, the boundary between the arrangement section on the arrangement l3 where good products continue and the arrangement section where defective products continue more than 5 pieces is evaluated as the boundary between the good products distribution region and the defective products distribution region, and a good semiconductor element P4 contacting with this boundary is selected. The boundary on each arrangement l1-l4 is obtained by this method to select the 8 good semiconductor elements P2-P9 positioned at the end of the good products distribution region. If the line connecting P2 to P7 and P8, P3 to P9 and P6, P4 to P7 and P9, and P5 to P8 and P6 each other is assumed to be the circumference of the good products distribution region within the wafer 1, the line indicated by a dotted line will be a boundary line, allowing the good products region to be obtained at the central section on the wafer surrounded by that line.

Title: Automatic pressure-regulating valve system
Inventor: UEDA YASUKIYO
IPC: F16K11/00
Filed: 1988-06-29
Abstract: PURPOSE:To dispense with any individual flow sensors by attaching a blade, rotating with both hot and cold water flows, to an automatic pressure-regulating valve for a combination device, while detecting the extent of rotation in the automatic pressure-regulating valve, and installing a flow detecting means for detecting both hot and cold water quantities. CONSTITUTION:A piston 21, operating with a secondary pressure differential after decompression, is locked to an intermediate position of a connecting shaft 8 for connecting a hot-water side valve body 4 and a cold-water side valve body 6 to each other, decompressing each primary pressure of a hot-water passage 1 and a cold-water passage 2, thereby constituting an automatic pressure-regulating valve. Two blades 10, 10, rotating with both hot and cold water flows, are attached to these valves 4, 6. An outer circumference of the piston 21 is magnetized, while a magnetoresistant element 24 is set up at the outside. With this formation, when hot water flows, the piston 21 rotates at rotational frequency conformed to the flow rate which is thus detected by a detector 25 via the magnetoresistant element 24.

Filed: 1981-10-14
Abstract: PURPOSE:To decrease a cycle time of measurement, by performing measuring action at a low speed only for a time, from when a contact piece is contacted to a work until the contact piece is separated from the work, and moving the contact piece at a high speed in the rest of a route of the contact piece.

An NC receives this skip signal 18 to stop an existing block and transfer to a low speed block from the next position 102 toward a position 103. During this time, the contact piece 12 is separated from the work 13, and a fall-down edge one-shot pulse generator circuit 21 outputs a pulse signal to again actively generate the skip signal 18 through the OR gate 22, then the existing block is switched to a high speed block from a stop position 104 to a position 105.

Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To attain a stable speed detection signal with a piece of magnet and cost reduction, by applying speed detection magnetization at the protruding end surface of the magnet, and forming a speed detection sensor facing a magnetized speed detection part. SOLUTION: A magnet 10 is disposed in the outer peripheral direction of an iron core 6 through an air-gap in a rotating shaft 9. In the magnet 10, a main pole magnetized part 10a and a speed detection magnetized part 10b are integrally formed, and a bonded and retained rotor frame 11 is fixed at the inner rings of bearings 2, 3 whose outer rings are retained at a housing 1. The magnet 10 is protruded farther than the end surface of the rotor frame 11, and speed detection magnetization is applied to its protruded part. A speed detection sensor 12 is formed at a position on a printed circuit board 5 facing the magnetized speed detection part 10b. As a result, it becomes difficult to receive the influence of the main pole magnetism against the magnetized speed detection, thus it is possible to obtain a stable speed detection signal easily, and attain high precision and cost reduction.
