Title: Method for stopping main engine at breakdown of deteriorated parts on water turbine or reversible pump turbine
Inventor: TAKAGI NOBUSUKE
IPC: F03B15/18
Filed: 1979-04-13
Abstract: PURPOSE: To prevent vibration of guide vanes of a reversible pump turbine by means that if a deteriorated guide vane is damaged and ready to turn in the closing direction, other normally operated guide vane may be kept opened.  
     CONSTITUTION: A guide vane and an inlet valve are simultaneously closed on the basis of instruction of a main engine stop caused by factors except a damage of a deteriorated parts. In operation, if a deteriorated parts are damaged, the closing action of the inlet valve is stopped and that opening of the valve at the point of the damage is kept. On the other hand, immediately after fully closing motion, another guide vane normally operated is opened, having the inlet valve fully closed from the rest of the closing motion. After current is shut off, the guide vane normally operated is fully closed. It is not until the revolutional speed of the main engine is low enough that a mechanical brake is used to stop the engine. As the flow rate of water leaking from the damaged guide vane is lower than that through another normally operated guide vane, water hummer is reduced and the guide vane can be prevented from vibration.

Abstract: PURPOSE:To prevent the winding destruction by setting the number of revolution of a traverse cam for the number of revolution of a package supporting shaft less than the number of revolution set for carrying out winding with a certain number of winding, in the short period at the start of winding. CONSTITUTION:In the short period at the start of winding, i.e., in a prescribed short period up to the formation of a package 1 having a diameter of 3-5mm on a bobbin 2, the number of revolution of a traverse cam 11 for the number of revolution of a package supporting shaft 4 is set less than the number of revolution set for carrying out winding with a certain number of winding. Afterwards, the ratio between the number of revolution of the package supporting shaft 4 and the number of revolution of the traverse cam 11 is synchronized with a ratio set for carrying out winding with the a certain number of winding. Therefore, the traverse width can be set constant from the start of winding up to the completion of formation of the package 1, and winding destruction is prevented.

Title: Aluminum made heat exchanger core
Inventor: ENOKIDO HIROAKI
IPC: B23K1/00
Filed: 1987-02-27
Abstract: PURPOSE:To improve the airtightness by an O ring and to secure the specific compressibility uniformly compressing over the whole body by leaving no residue of non-corrosive flux on the annular recessed groove of a seat plate. CONSTITUTION:Water is mistily sprayed from plural spray nozzles 41 on an Al made heat exchanger core 40 temporarily assembling a tube 31, fin 32 and seat plate 33 of Al materials respectively. In this case, since the tube 31 is press-fitted into the joining part of the tube 31 and seat plate 33, each joining part is small and not immersed to the annular recessed groove face side of the seat plate 33. The non-corrosive flux in powder body is then sprayed on the core 40 by a powder coating gun 42 but is not stuck to the place where no water is sprayed. It is thereafter dried and subjected to brazing treatment inside a heating furnace to obtain an Al made heat exchanger core 30. Since it is treated so as to be not stuck inside an annular recessed groove 34 no noncorrosive flux remains on the inner face of the recessed groove 34. The need for cleaning the groove 34 inner face is eliminated and yet the airtightness of the O ring and synthetic resin made tank which are engaged at the later stage is secured.

Title: Exchange module standby changeover system
Inventor: ONISHI KOICHI
IPC: H04Q11/04
Filed: 1992-03-02
Abstract: PURPOSE:To reduce the hardware quantity and the software processing quantity by providing an STM share device in the system. CONSTITUTION:When an exchange module 6 is faulty, an operation center 9 gives a command of switching a subscriber termination module 11 accommodated by the module 6 into a standby exchange module 7 to a control section 4 of an STM share device 3. The control section 4 switches the STM pulse and returns its reply signal to the center 9. Subscriber data are transferred from the module 6 to the module 7. After the changeover, when the module 6 is recovered, the center 9 gives a switch-back command from the module 7 to the module 6 to the control section 4. The interrupt of a call during talking is avoided by transferring the information relating to setup during connection from the module 7 to the module 6 before the switch-back. Since channels of plural calls are managed and controlled altogether, the hardware quantity and the software processing quantity are reduced.

Title: Bump forming device
Inventor: OKAMOTO KIMIO
IPC: H01L21/60
Filed: 1990-02-26
Abstract: PURPOSE:To improve reliability by press-forming electrodes heads formed on a wafer using a flat plane. CONSTITUTION:Electrode heads are pressed by a pressing plate 8 and are plastically deformed to be flat planes. A pressure sensitive element 9 detects pressure (50-80gr per one bump) at which the plate 8 deforms the heads. When the pressure reaches the prescribed pressure, the element 9 stops a pressurizing motor 12. The motor 12 reversely rotates after stopping for several minutes and the plate 8 is ascended by a vertical motion block 10 to return as before. Then, the X stage of a X-YZ stage 15 shifts the X size of a semiconductor element, a new element is positioned directly under the plate 8 and the motor 12 normally rotates so as to press-form the head. When the formation of one X line is completed, the Y stage of the stage 15 shifts only the Y size of the semiconductor element and the formation is shifted to a new X line. The recognition of the edge of the water 1 is carried out by a camera 16, a defective mark given at the time of probing test is recognized and the press-formation of a defective semiconductor element is skipped. Thus, the height of the bump electrode is fixed, contact area is increased and reliability is improved.

Title: Method for supplementing object connecting part
Inventor: TOMONO MASAHIRO
IPC: G06T13/00
Filed: 1988-02-26
Abstract: PURPOSE:To reduce the required quantity of information by providing a connector for connecting a partial object, defining the coordinate of the vertex of the partial object to be the face information of the connector and forming the form of the connector based on this face information. CONSTITUTION:The counter 3 covers a plane on the gap between the partial objects 1, 2, thereby supplementing the gap. For instance, as the plane, there are planes p1, p2, q2, q1, planes p2, p3, q3, q2 or the like. Since these faces use the vertexes of the partial objects 1, 2 as constituting vertexes, a supplementing plane is automatically deformed by following to the change of the positions of the partial objects 1, 2 to constantly supplement the gap between the partial objects 1, 2. In such a way, the vertex information of the objects 1, 2 is directly used as the constituting vertexes of the connector 3. Thereby, the quantity of the required information may be reduced.

Title: Information record medium, manufacture of its master disk and photodetector using it
Inventor: NAGATA TAKAYUKI
IPC: G11B7/26
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To perform multi-valued recording and no realize high data density and a high data transfer rate by forming a recording mark with ruggedness on a recording surface and making the sectional shape of the recording mark asymmetry related to a center of a track on which the recording mark is formed. SOLUTION: A pit 2 being the rugged recording mark having a certain phasic depth is formed along the track center 1 of an information record medium. When a light spot 3 scans on this record medium along the track center 1, a reflection light quantity is changed remarkably according to the presence of the pit 2 in the light spot 3. Then, by binarizing a sum signal S1 between photodetectors 4a, 4b with a prescribed threshold value, the presence of the pit 2 is discriminated. Further, reflection luminous flux causes deviation in a light quantity distribution by the pit 2. Then, the information is discriminated according to positive/negative of a difference signal S2 between the photodetectors 4a, 4b. Thus, the multi-valued recording is performed.
