Patent JP-H03205877-A (JP)
Title: Insulated gate field effect transistor
Inventor: TAKAO NORIYUKI
IPC: H01L29/78
Filed: 1990-01-08
Abstract: PURPOSE:To enable suppression of parasitic transistor's actions and prevention of breakdown due to surge and others while suppressing leakage current upon application of reverse bias by introducing lifetime killers only into a base region at the zone where a depletion layer does not reach upon application of reverse bias. CONSTITUTION:The design is such that a region 2 that is reverse to a source region 7 and a drain region 1 in conductivity and includes the channel zone contains the lifetime killer and that a depletion layer 9 extending to the region 2 including the channel zone contains substantially no lifetime killer upon application of reverse bias onto the junction between the region 2 and the drain region 1. For example, a polycrystalline silicon film 4 serving as the gate electrode is used as a mask to diffuse boron into a silicon substrate serving as the N<->type drain region 1 to form a P type base region 2. A CVD silicon oxide film 10 is grown and patterned into a mask, which is in turn combined with the mask of polycrystalline silicon film 4 to form an N<+>type source region 7, and a lifetime killer such as platinum is diffused using the same mask.

Title: Method for testing wall thickness and withstand voltage of insulating tube and external electrode used therefor
Inventor: YAMANAKA KAORU
IPC: G01R31/12
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To test the wall thickness and withstand voltage of an insulator tube while the tube is put upon another tube on a pallet by providing at least one external electrode and internal electrode arranged on the internal surface of the tube and applying a voltage across the electrodes. SOLUTION: An external electrode 1 is formed so that the diameter of the part (winding part) put around the barrel section 12 of an insulating tube 10 in a free state is made a little smaller than that of the barrel section 12 so that the electrode 1 can be closely adhered to the section 13 by utilizing the spring property of the winding part at the time of mounting the electrode 1 on the tube 10. When the winding part holds the section 12 after the winding part is opened, the electrode 1 is closely adhered to the section 12 due to the spring property of the wire constituting the electrode 1.  The electrode 1 is constituted by electrically connecting a plurality of external electrodes to each other through a conductive chain, etc., and an internal electrode is constituted by fitting a metal sheet to the internal surface of the tube 1 so that the sheet can be brought into contact with the internal surface over the entire length. The wall thickness and withstand voltage of the tube 10 are measured by applying a prescribed voltage across the electrodes.

Title: Radio communication equipment
Inventor: SAITO KATSUO
IPC: H04B1/707
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To attain phase adjustment independently of precision and deviation in a phase shift means by controlling a phase of a recovered carrier so that a phase of a recovered carrier signal through inverse spread processing and a phase of a carrier signal extracted from a reception signal are in phase to each other. SOLUTION: An IF(intermediate frequency) signal 12 of a received multiplex signal is inversely spread by an inverse spread demodulator 13 based on an inverse spread signal PN0 and a recovered carrier component is given to a phase shifter 19 via a BPF 16 and an amplifier 18 and its output is fed to a base band demodulator 28. On the other hand, an IF carrier signal 23 is extracted from the reception IF signal 12 via a multiplexer 20 and a frequency divider 22 and a phase detector 24 is used to detect a phase difference with the phase of the recovered carrier 25. The phase difference is converted into a DC voltage by an LPF 26 and the phase shifter 19 is controlled so as to make the phase difference zero. Thus, the phase adjustment due to the precision or deviation of the phase shifter or dispersion in a narrow band filter is not required.

Filed: 1985-01-10
Abstract: PURPOSE:To obtain high inspection accuracy by coating further the surface of a metal which coats the surface of a conductive pattern with a metallic layer having high reflectivity to a laser beam. CONSTITUTION:The laser consisting of He-Ne having the reflectivity higher than the reflectivity of other metals when irradiated to copper is diffused with lapse of time by a reflecting mirror 2 which rotates the laser beam 1 to irradiate the beam 1 perpendicularly to a printed circuit board 4 by a lens 3.

Abstract: PURPOSE:To provide the slip data preparing device which can make slip data into a data base easily for a user or the like and can facilitate the use of the slip data by relaxing a limitation for the filed data structure of a data base file. CONSTITUTION:This device 10 is provided with an FC information storage part 11, buffer memory 13, display part 14, input part 15 and control part 16.

SOLUTION: The drawing regulating structure of a multistage cassette comprises a lock protrusion piece 90 protruded from the size in the direction of width of a feed paper cassette at each stage; and a lock plate 11 arranged on the inner wall surface of a duplicator body 1a in such a state to correspond to the lock protrusion piece 90 and co-rotating around a vertical axis.

Title: Copy controlling method
Inventor: KISHI HAJIME
IPC: B23Q35/121
Filed: 1984-01-10
Abstract: PURPOSE:To prevent a tracer head from malfunction due to vibration by moving the tracer head with respective speed signals in the direction of tangent and normal to a model according to the difference between composite displacement of each shaft generated from the tracer head and a reference displacement. CONSTITUTION:When an abnormal vibration occur in the forward and backward surface copying and a tracer head is included excessively in a model or largely spaced from the model, the difference DELTAepsilon between composite displacement and a reference one becomes large and tangential speed signal VT=0 is obtained. This is immediately detected by a speed signal monitoring circuit which generates switching signal CHS. Then, an input resistance change-over unit 104a of a speed signal calculating circuit 104 sends DELTAepsilon to the input of the resistance R2 side to lessen the gain of an amplifier 104b. Thus, normal speed signal VN is reduced according to the characteristics and vibration component is also reduced. and since VN is reduced, the effect of vibration is reduced, stable copying becomes possible and VT is generated so that the unit 104a sends DELTAepsilon to the input of the resistance R1 side to recover the gain of the amplifier 104b.
