Title: Method for taking out gate lead and auxiliary cathode lead of thyristor having flat package
Inventor: HONDA AKIRA
IPC: H01L29/74
Filed: 1985-02-20
Abstract: PURPOSE:To implement a high speed, by determining the taking-out positions of a gate lead and an auxiliary cathode lead so that the direction of the magnetic flux formed by a gate current flowing to the auxiliary cathode lead from the gate lead becomes reverse with respect to the direction of the magnetic flux formed by a cathode current flowing through a cathode electrode, thereby preventing the fall down of the gate current at the time of turn ON. CONSTITUTION:A node 4 and a cathode 3 of a GTO 1, which is enclosed in a flat package, are compressed by conductors 41 and 31, respectively, and connected to an external power source EG and an external circuit RG. From the GTO 1, a gate lead 5 and an auxiliary cathode lead 6 are taken out. A gate current iG is supplied. At this time, the taking-out positions of both leads are determined so that magnetic flux PHIG formed by the gate current iG flowing to the auxiliary cathode lead 6 from the gate lead 5 and magnetic flux PHIK formed by a cathode current iK have the reverse directions. Then, induced electromotive force ei due to the change in ik at the time of turn ON is generated in the direction increasing iG. Therefore, fall down of the gate current iG at the time of turn ON, is prevented, and the high speed turn ON is ensured.

Title: Cooling system for underground tunnel
Inventor: SHIMIZU TOSHIO
IPC: H02G9/08
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a cooling facility by a method wherein a water tank for rainwater storage is installed on the surface of the ground, a water tank for cooling-water storage is installed deep under the ground, both water tanks are connected with a pipe, and cooling water in the water tank for cooling-water storage is sent out to an underground tunnel by using a water supply pump. SOLUTION: Rainwater or groundwater which is stored in a water tank 1A for rainwater storage installed on the surface of the ground, or in a water tank 1B for groundwater storage installed in the ground is sent to a water tank 3 for cooling-water storage installed deep under the ground via a filtration filter 2 by a pipe 4A or 4B. In this manner, cooling water which is stored in the water tank 3 for cooling-water storage, and which is sent at an arbitrary flow rate absorbs a heat quantity generated by a power cable inside an underground cave road 6, and it is discharged to the outside from the end part of the underground cave rod 6.  Consequently, the cost of obtaining the cooling water can be reduced, the cost of lowering the cooling water to a water temperature suitable for cooling the cave road can be reduced, and the cost of collecting the cooling water can be reduced because the cooling water is not collected so as to be discharged to the natural world from the end part of the cave road.

IPC: H01L27/06
Filed: 1992-02-19
Abstract: PURPOSE:To prevent latch-up due to a parasitic thyristor of a P-N-P-N junction. CONSTITUTION:A Be-doped P-type layer 2 or a B-doped P-type layer 2a in which resistivity becomes 1/2-1/3 of that of a P-type silicon substrate 1 is formed on the substrate 1 by ion implanting.

Abstract: PURPOSE: To increase the number of parked bicycle by releasing the wedge of a handle fixing part, releasing meshing of a connecting rod with a fixing tool, making a handle turnable by 90deg. in parallel to the ground and by fixing the handle by a lift of the fixing tool by means of a spring inside of the handle fixing part. CONSTITUTION: Meshing of the top part 7a of a connecting rod 7 with a handle 6 is released and the handle makes horizontal turn clockwise or counterclockwise by being slightly pushed by releasing the fixing pin 5 of a handle fixing part A, demounting a wedge 4 and slightly pushing a handle fixing tool 6 slightly downward. Thereby, the handle becomes turnable by 90deg. in parallel to the ground. Furthermore, the handle is so constituted as becoming fixable as it is by a lift of the handle fixing tool 6 by means of a spring 8 mounted inside of the handle fixing part A. Namely, since the top part 7a of the connecting rod 7 and the handle part are placed in mutual rectangular fitting, mutual meshing may be achieved again by turning thereof by 90deg. Therefore, a bicycle parking place area can be reduced by making the handle capable of turning by 90deg. in parallel to the ground.

Title: Production of liquid crystal display device and liquid crystal charging device
Inventor: HIUGA SHOJI
IPC: G02F1/13
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a production method for liquid crystal display device and a liquid crystal charging device where the charging quantity of liquid crystal is prevented from being too much or too less by directly monitoring the charging state of liquid crystal to a gap. SOLUTION: In the process of liquid crystal charging to the gap between first and second transparent substrates 10 and 20 stuck to each other with a prescribed gap 31 between them out of production processes of a plastic film liquid crystal display panel, the light transmittance in the position which liquid crystal LC will reach last in the gap 31 is monitored by a light source 61 and a light reception element 62. When charging of liquid crystal LC advances to this position where the light transmittance is monitored, the light transmittance in this part is reduced. Consequently, the timing of the end of charging of liquid crystal LC can be accurately recognized based on the monitor result of the light transmittance, and the charging quantity of liquid crystal is prevented from being too much or too less.

Title: Cylindrical body feed device
Inventor: OUCHI MASATOSHI
IPC: B65G39/18
Filed: 1988-02-12
Abstract: PURPOSE:To enable the support of a cylindrical body at a point without any dislocation from a center point even if there is any bend in the body by applying the constitution wherein the cylindrical body is being held and supplied on three sets of rollers so energized as to contact the body. CONSTITUTION:The rollers 1a, 1b and 1c and each roller at an upstream side have the spherical surfaces in parallel to the feed direction of a log A and rotate in contact with the aforesaid surfaces, actuated with respective drive sources. The log A is thereby supplied and the bark thereof is peeled, using high pressure water from a nozzle. When the bent part of the log A reaches a roller group at a downstream side during the feed process, each of the rollers 1a, 1b and 1c is shifted in the radial direction of the log A depending upon the degree and direction of curvature at the bent part, as the rollers 1a, 1b and 1c are energized toward the log A with cylinders 2a, 2b and 2c. It follows, therefore, that the peeling of the bark can be properly carried out, as the high pressure water is always injected constantly.
