Patent JP-S58171862-A (JP)
Title: Manufacture of semiconductor device
Inventor: SATOU NORIAKI
IPC: H01L29/78
Filed: 1982-03-31
Abstract: PURPOSE:To form an element into a fine structure and of high withstand voltage by a method wherein one conductivity type impurity is introduced into the surface of a semiconductor substrate by an ion implantation method, deeper than the implantation depth of reverse conductifity type impurity which was already introduced. CONSTITUTION:The P type impurity is implanted into the surface of the Si substrate 1 by an ion implantation method with a gate electrode 12 as a mask. Thereat, the implanted energy is enhanced to approx. 140-180KeV more than the implanted energy (50KeV approx.) which is generally used, and then boron is implanted to the position deeper than the implantation depth of the N type impurity 13. As a result, since the end part 9 of a P<+> type region 17 is far away in the distance from a diffusion source, compared with one of a conventional DSA structure, the density decreases. The width thereof is formed thick, since the top end position of the diffusion source is stretched out further to the inside than that of an N type region 16. Therefore, a withstand voltage higher than conventional one can be obtained, and accordingly the element can be formed into a fine structure.

Abstract: PURPOSE:To facilitate bending of a trim product and to obtain the product having a stable shape without variance in a bending shape by providing projecting preliminary parts in the places to act as a fulcrum part when a trim is bent transversely. CONSTITUTION:A mandrel 6 for a trim is formed by providing transverse long holes 6a at a prescribed interval in the longitudinal direction of a belt-like metallic plate and cutting slits 6b for parting on both side parts opposite to the holes 6a. Two projecting preliminary parts 6C are provided near the center of the mandrel 6 along the longitudinal direction. The positions of the parts 6c are set in the positions where said parts act as a fulcrum part for bending when the mandrel part of a trim product for which the mandrel is used is bent in the transverse direction theeof. The parts 6c are formed in the prescribed positions when the mandrel 6 is passed continuously between upper and lower recess- and projection forming rollers.

Filed: 1987-03-10
Abstract: PURPOSE:To reduce the diameter of the insertion part of an endoscope by forming at least a part of the front end constituting part with a transparent member and burying a solid image device (SID) chip in this part. CONSTITUTION:An SID chip 9 arranged on an SID substrate of a first front end constituting part 1 by die bonding is buried in a second front end constituting part 2, which is formed by packing a light-transmissive transparent resin, between a third front end constituting part 3 and the first front end constituting part 1 so that the image pickup surface of the front of the chip 9 faces as objective optical system 4. The SID chip 9 buried in this manner is connected to an electric circuit board 12 arranged on the rear face of the first front end constituting part 1 through the first front end constituting part 1 consisting of the SID substrate by a bonding wire 11 consisting of platinum, gold, or the like. Since it is unnecessary to package and attach SID chips individually, the diameter of the front end part of an endoscope is narrowed.

Title: Magnet catch with attraction magnet at time of vibration
Inventor: HASHIZUME HIROKO
IPC: E05C19/16
Filed: 1995-02-05
Abstract: PURPOSE:To prevent opening of a hinged door when vibrations are generated by rotatably mounting a holder with an attraction magnet at the time of vibrations apart from a magnet catch used for normal opening and closing. CONSTITUTION:A magnet catch with an attraction magnet at the time of vibrations has a magnet 44 used for the normal opening and closing operation of a hinged door 62, and the magnet 44 is attracted onto an attraction plate 20 consisting of a magnetic substance on the hinged door 62 and the closed state is held. The attraction magnet 47 at the time of vibrations is mounted movably back and forth on a holder 82 rotated centering around a shaft 83 to a holding plate 42 apart from the magnet 44. The attraction magnet 47 at the time of vibrations is moved forward by shaking when vibrations are generated, and attracted onto the attraction plate 20 by magnetic force when the magnet 47 is shifted forward in a certain extent or more while a pawl body 63 is engaged into the hole 21 of the attraction plate 20. The revolution of the hinged door 62 is inhibited by an elastic means 64 such as a spring. The engagement of the pawl body 63 is released when the magnet 47 is drawn by force larger than magnetic force for opening the hinged door 62.

Title: Capacitive load driving circuit, driver for liquid crystal display device using driving circuit, liquid crystal device using driver, and capacitive load driving method
Inventor: KIMURA YUICHIRO
IPC: G09G3/36
Filed: 1989-03-09
Abstract: PURPOSE:To attain a speedy response with low power consumption by supplying a current to the source terminal of a transistor(TR) from a 2nd current source connected to a 1st current source in parallel only for a certain period in the falling of an input signal. CONSTITUTION:The 2nd current source 4 is connected to the source terminal of the TR3 in parallel to the 1st current source 5. The current of the 2nd current source 4 can be supplied or cut off by a switch circuit 6. Then the operation of the switch circuit 6 is controlled by a control circuit 10 so that the current of the 2nd current source 4 is supplied only for the temporary period in the falling (or rising) of the input signal. Consequently, only when a capacity with a capacitive load is discharged, a large bias current flows through the 1st and 2nd current sources 5 and 4. When the load capacity is charged and the input signal has no variation in other periods, the current of the current source 4 is cut off and a small bias current is supplied only through the current source 5. Consequently, the fast response can be attained with the low power consumption.

IPC: G05B19/4097
Filed: 1992-03-13
Abstract: PURPOSE: To accurately remove materials and to improve the productivity by using solid models and Boolean operation to generate an NC tool route. CONSTITUTION: In the example of a stock model 301 displayed on a CRT picture, a clamp 302 holds a stock 301 on a working table. A parts model 301 is subtracted from the stock model 301 with solid model ring Boolean operation to automatically generate delta volumes 501 to 503. At this time, the solid model of parts 201 is positioned on the inside of the stock 301, and parts 201 are subtracted from the stock 301 to define the delta volumes. For example, the delta volume 501 is the volume of the stock 301 which doesn't remain in parts 201. The delta volume 502 is a cylinder of materials to be removed for boring. Consequently, a machine tool is so programmed that materials defined by these delta volumes are removed, thereby producing parts 201.
