Title: Device for measuring position of rotary steel shaft and manufacture of truck for said device
Inventor: MARUKU TEIBOU
IPC: G01P3/48
Filed: 1990-01-17
Abstract: PURPOSE: To make a signal larger and to protect the surface of a strip made of an insulating material coated with a nonferromagnetic material by sticking the strip to a shaft by using the non-ferromagnetic material-side surface. CONSTITUTION: A device for measuring the position of a steel shaft 1 is incorporated with a Foucault current sensor in such a way that a track 3 can move in front of the sensor 2. The track 3 is constituted of a strip 4 containing nonmagnetic materials, preferably, rectangular copper surfaces 5 regularly distributed around the shaft 1. The strip 4 is formed by depositing a copper layer on a substrate made of an epoxy piled material and partially removing the copper layer so that only the copper surfaces can be left by electric discharge machining. The strip 4 is stuck to the shaft 1 so that the copper surfaces 5 can be faced to the shaft 1. The adhesive 6 used for sticking the strip 4 to the shaft is selected so that the strip 4 cannot be removed even when the strip 4 is subjected to a strong tangential stress or centrifugal force.

Title: Semiconductor device case
Inventor: KAMIYA YUKIO
IPC: H01L23/36
Filed: 1992-01-21
Abstract: PURPOSE:To miniaturize a device and reduce a heat sink mounting work manufacturing cost and terms, by making a case surfaced with a spray deposit of a metal film serve as the principal part of a radiation function zone. CONSTITUTION:A ceramic-made pingrid array IC package is an application object. That is, in an IC package employing a normal ceramic case 1 completed by coupling a heat sink, one in a state just before the heat sink is coupled is surfaced with a spray deposit of a solder film 8. In other words, normally a heat sink is coupled on the top of a copper tungsten plate 2; but instead a solder film 8 is formed. This constitution makes heat generated in the IC chip 6 transmitted to the solder film 8 via the copper tungsten plate 2, but transmitted rapidly to the whole of the solder film 8 and released into air because the solder film 8 has a thermal conductivity much better than that of ceramics and others.

Title: Screw connecting mechanism
Inventor: SHIRAISHI WATARU
IPC: B29C45/17
Filed: 1990-01-19
Abstract: PURPOSE:To simplify the operation at the time of replacing a screw and prevent tension and compression strengths from getting lowered by forming a screw base section into a structure to be incorporated in a screw sleeve by a retainer and a retainer holder. CONSTITUTION:A retainer 5 is set in a recessed section 21 between a screw sleeve 6 and a retainer holder 9 is fixed to the screw sleeve 6. At that time, the position of a given inserting opening 20 of the retainer holder 9 and the position of a given channel 14 of the screw sleeve 6 are conformed with and fixed thereon. A base section of a screw 1 is fitted in from the front of the retainer holder 9 and a lever 15 is operated at the other end B side, and the rear surface of the retainer is brought into contact with a front end surface 11 of the key 10 by the rotation. The relative rotation of the base section of the screw 1 together with the screw sleeve 6 is prevented by said arrangement to prevent the base section from slipping out forward and is connected with the screw sleeve 6 by said arrangement. Thus, the tension and pressing force to the screw are transmitted by the key, and it is not necessary to form a ring channel on the base section of screw, which enhances the tension strength and compression strength of the screw.

Abstract: PURPOSE:To automatically control the pressure in a proportional counter tube at a constant variation by operating an exhaust or suction solenoid valve by way of an electric power discriminator by the voltage detecting the pressure in the proportional counter tube when said pressure rises or drops by exceeding a predetermined range. CONSTITUTION:When the internal pressure of a proportional counter tube 4 is wintin a normal pressure range, the detection voltage attenuating 7 the output of a pressure sensor 5 is between the respective discrimination voltages E1 and E2 of electric power discriminators 11, 12, and does not output the control signal from the discriminators 11, 12, hence solenoid valves 3, 6 are not operated. Next, when the internal pressure of the pipe 4 rises and exceeds a normal pressure range, the detection voltage rises higher than the discrimination voltage E1, and the discriminator 11 outputs a control signal, thereby ON controlling the exhaust solenoid valve 6. Similarly, when the internal pressure of the tube 4 drops, the suction solenoid valve 3 is ON controlled by the control signal from the discriminator 12. Thereby, the pressure in the tube 4 is automatically controlled at a fixed variation.

Title: Optical fiber-coloring device and coloring control for optical fiber
Inventor: YAMAGUCHI RIKA
IPC: G02B6/44
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To enable stable coloring of optical fiber without reduction of operation efficiency, even when the linear speed of optical fiber coloring changes during the radiation with ultraviolet rays. SOLUTION: A linear speed detector 8 detects the linear speed of an optical fiber 2 or bundles of optical fibers, while the fiber or the bundles are irradiated with ultraviolet rays. An exposure dose controller 9 varies the exposure dose of an ultraviolet radiation lamp 5 based on the relationship between a previously calculated linear speed and a required illuminance, and the detected linear speed. Thus, the optical fiber or the bundles can be irradiated with an optimal radiation for optical fiber coloration corresponding to the linear speed of the optical fiber or the bundles whereby the photosetting degree of an ultraviolet- setting resin to be colored can be kept constant to stabilize the coloring state and reduce the fluctuation of the product quality.  In addition, the carbonization caused by excessive radiation with ultraviolet rays can be avoided to decrease the occurrence of soot to reduce the staining of the ultraviolet lamp 5 and improve the operation efficiency.

Abstract: PURPOSE:To reduce the concentration of dissolved oxygen in pure water by providing a hermetically-sealed vessel which can accommodate a water washing bath whole and also to which a vacuum pump is connected by a vacuum piping, and by reducing a pressure in this hermetically-sealed vessel. CONSTITUTION:A wafer 1 for which treatment by an acid and others is ended is immersed, for each wafer carrier 2, in a water washing bath 3 filled up with pure water 4 so as to be washed by water. In this case, a hermetically- sealed vessel 5 which can accommodate the bath 3 whole, a vacuum pump 6 and a vacuum piping 7 connecting the vessel 5 with the pump 6 are provided. The pump 6 reduces a pressure in the vessel 5 to which it is connected by the piping 7, and thereby the concentration of dissolved oxygen in the pure water 4 in the vessel 5 can be reduced. Since the concentration of the dissolved oxygen in the pure water 4 can be reduced by reducing the pressure in a water washing part, in other words, formation of a low-rank oxide film, for instance, can be held down. As for other methods, a method of spraying the pure water 4 against the wafer 1 being transferred by a belt can be mentioned as well, and the same effect can be produced by providing the water washing part in the vessel 5 and by reducing the pressure therein.
