Inventor: ASAKINO KUNIHIRO
IPC: G01P3/36
Filed: 1987-07-29
Abstract: PURPOSE:To easily and accurately obtain the speed of a moving body by inputting the prescribed position of the moving body as a video signals and measuring the speed from the prescribed time quantity of the shifting of the moving body image on a CRT screen. CONSTITUTION:The prescribed position (e.g. the tip of rod steel whose length is measured) of the body which moves at a constant speed is detected by a position detector 2 which uses laser light, etc., and its signal is used as a trigger to input an image by an ITV camera 3. This signal is A/D-converted 4 and stored in a memory 5, and the image is displayed on a CRT 7 through a CPU 6. Then the image of the tip position of the rod steel 1 which is a constant time later is inputted similarly and stored in another memory base of the memory 5, and then it is processed and recognized similarly. At this time, when the position relation of the optical system including the camera 3 is constant and video signal scanning conditions are constant, the quantity and required time of shifting are recognized from the data in the memory 5 through image processing because the length of the rod steel is measured previously, thereby calculating the speed.

Title: Method of severing and treating wire material
Inventor: NOJIMA TORU
IPC: B23D36/00
Filed: 1984-09-06
Abstract: PURPOSE:To make it possible to manage the production control of fixed length wire materials and short fixed length wire materials, by retro-feeding ununiform length wire materials at the change-over point from the primary cutting of fixed length materials to the secondary cutting of short fixed length materials, and by lifting up short length materials to commonly sever the remaining short length materials after completion of cutting the other fixed length materials. CONSTITUTION:All wire materials are severed with a primary severing mode to a predetermined length, and since rolled materials 2, 6, 10 belong to a mode change-over point, these wire materials are retro-fed to a lifter device which lifts up short length materials 8b while the other wire materials are severed with the primary severing mode. At this position, since rolled materials 4, 8 also belong to the mode change-over point, the other materials are successively severed with the primary severing mode. With the repetition of these steps the first severing mode is completed. Then, of the short length materials which have been lifted up, those which have a common severing pattern and have the least number in the severing pattern of the primary severing mode just before, are lowered onto a table, and are severed to a fixed length in accordance with a secondary severing mode. When it reaches a point at which the severing pattern is altered, the severing is similarly repeated to complete the secondary severing which may be made under the control of production.

Title: Nuclear reactor for vessel
Inventor: YAMAMURA TOSHIO
IPC: B63H21/18
Filed: 1994-07-18
Abstract: PURPOSE:To enhance the passive safety unforeseen situation by providing a differential pressure regulator for regulating the inner pressure difference between a heat insulating layer and a container, and a pressure regulator for suppressing the inner pressure of the container below a design level. CONSTITUTION:When the inner pressure P of a container 5 begins to increase due to rupture of piping in a primary containment vessel 2, the pressure difference from the inner pressure P1 of a heat insulation layer 3 increases. A detector 15 detects the pressure difference and feeds an working gas from a compressor 21 through a converter 16 thus opening a pressure regulation valve 17. Consequently, high pressure gas flows from a gas cylinder 19 into the heat insulation layer 3 to suppress the differential pressure ¦P1-P2¦ lower than a design outer pressure of a watertight vessel 4 thus protecting the vessel 4 against destruction. When the inner pressure P1 of the heat insulation layer 3 increases furthermore and a relief valve 9 is opened to discharge the high pressure gas into the container 5, pressure in the container 5 is regulated through a pressure regulator 24 coupled with the outside of the container 5.

Title: Motive power transmission switch mechanism for magnetic recording tape driver
Inventor: SAITO SHINICHI
IPC: G11B15/26
Filed: 1984-09-07
Abstract: PURPOSE:To delete the noise produced when the transmission of motive power is switched and to prevent a time delay of the revolving power, by revolving a drive rotary member to move it to the 1st and 2nd position and having a contact between an oscillating lever and an oscillation regulating member to absorb the impact force to an absorbing member when the revolving power is transmitted to the 1st or 2nd rotary member. CONSTITUTION:An output shaft 74 of a motor 72 revolves counterclockwise with the recording start signal, and a mobile gear 78 is energized counterclockwise round the shaft 74 together with an oscillating lever 76. The gear 78 engages an idler gear for a capstan 22 and revolves the capstan 22 clockwise. In this case, an oscillating distance prescribing projection 86 of the lever 76 is detached from an oscillation prescribing member 84 at one side and has a contact with an oscillation prescribing member 84 at the other side. The impact force produced from the contact between the lever 76 and the member 84 is absorbed by an absorbing member 88 attached to the projection 86. Therefore the projection 86 has no jump over the member 84, and the gear 78 has no spring on a gear 70. This produces no delay to the transmission of the revolving power of the motor 72 to the gear 70. Furthermore no noise is produced.

Abstract: PURPOSE:To prevent the cooling irregularity of the outer peripheral surface of a cylindrical thermoplastic resin by bringing a hydrous strip material into contact with the outer peripheral surface of the cylindrical thermoplastic resin passing through the inlet of a cooling tank and closely bonding the same to the outer peripheral surface of the thermoplastic resin by a backup material and closing the gap between the inlet peripheral edge part of the cooling tank and the backup material by a packing. CONSTITUTION:An extruded cylindrical thermoplastic resin 2 enters a cooling tank 2 from an inlet 61 and a hydrous strip material 4 is brought into contact with the outer peripheral surface of the thermoplastic resin 2. A backup material 5 composed of a steel strip material is attached to the outside of the hydrous strip material 4 to be closely bonded thereto. As a result, water is not leaked from this bonded part. A rubber packing 7 is attached to the part between the backup material 5 and the peripheral edge of the inlet 61 and the leakage of water from this gap part is prevented. Since the surface of the thermoplastic resin advances while slides along the surface of the hydrous strip material, the entire peripheral surface of the thermoplastic resin 2 is uniformly cooled and no cooling irregularity is generated.

Title: Plasma processing method
Inventor: GODAIIN HIRONORI
IPC: H01L21/3065
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To enable plasma to be quickly stabilized in a process of etching an Si film layer with use of Cl2. SOLUTION: A wafer W is mounted on a lower electrode 106 disposed within a processing chamber 104 of an etching apparatus 100, and a predetermined rate of Cl2 is introduced into the chamber 104. A pressure in the chamber 104 is set at an initial level by adjusting the amount of Cl2 to be discharged. The initial pressure is found by processing the wafer W having a coverage ratio (of an area of an SiO2 divided by an area of an Si film layer) varying depending on the flow rate of Cl2, finding a difference between internal pressures of the chamber 104 before and after plasma generation, and adding a value obtained from the coverage ratio and pressure difference to a processing pressure value.  When a high frequency power is supplied to a lower electrode 104 for plasma generation after the internal pressure of the chamber 104 reaches the initial pressure, the pressure dropped after the plasma generation becomes substantially equal to the processing pressure, and thus stable plasma can be realized.
