Title: Electrostatic discharge circuit
Inventor: TAIRAA EI ROURII
IPC: H01L27/02
Filed: 1992-01-16
Abstract: PURPOSE: To protect a semiconductor integrated circuit against electrostatic discharge. CONSTITUTION: To shunt a surge voltage generated owing to electrostatic discharge a bipolar transistor(TR) 35 and a bipolar diode 36 are connected to an input pad 21 of the integrated circuit. They shunts an excessive current from an area which is easily damaged with a uniform current distribution that minimizes the damage. A diode clamp and a bipolar circuit 25 which has an optimum reverse bias yield voltage from a collector to a base are used. To improve immunity to the electrostatic discharge which is applied as a positive voltage to a source voltage VSS, reverse bias yield voltages of a diode and a transistor operating as a collector/base diode are reduced in areas 38 and 39 respectively. This circuit provides easy low-cost technology which achieves protection against electrostatic discharge in the most standard CMOS manufacture process without adding any other process.

Title: Acceleration detector
Inventor: NISHIZAWA YUKIO
IPC: G01P15/13
Filed: 1991-02-19
Abstract: PURPOSE:To downsize, simplify and reduce a cost of a servo-type acceleration detector wherein a displacement amount of a mass body which moves according to acceleration is detected by a displacement detection unit, an electric signal from the displacement detection unit is amplified and fed back to a torquer coil, the mass body is returned to a balanced point of zero displacement by electromagnetic force generated on the torquer unit and input acceleration is calculated from current flowing in the torquer coil at this time. CONSTITUTION:A differential transformer type displacement detection unit comprises a movable magnetic body 4 fixed on a plate spring 3, primary coils 5a, 5b and secondary coils 6a, 6b. A torquer unit which generates magnetic attraction force at both ends of the movable magnetic body to return the movable magnetic body to the balanced point comprises two torquer coils 7a, 7b, the movable magnetic body 4 and displacement stoppers 8a, 8b attached to a case 2 of the magnetic body. Thus the displacement detection unit and the torquer unit are integrated thereby simplifying, downsizing and reducing a cost of the structure. Since a differential transformer type displacement detection unit does not require airtightness, this is advantageous in cost also in this regard.

Abstract: PURPOSE:To improve COD level by arranging an optical waveguide layer between a first clad layer and an active layer, separating a light emitting region of laser rays from a current blocking layer, and stabilizing light mode. CONSTITUTION:On a substrate 1, the following are epitaxially grown; a first clad layer 2, an optical waveguide layer 3, a multi quantum well layer, a second clad layer 5, and a cap layer.

By repeating epitaxial growth and etching, a current blocking layer 6 and a contact layer 7 are formed; a P-side electrode is formed thereon; an N-side electrode is formed on the substrate 1. An optical waveguide layer 3 having intermediate refractive index is arranged between the active layer 4 and the first clad layer 2. Light distribution is shifted to the optical waveguide layer 3 side. Thereby, the oscillation region of laser rays is separated from the current blocking layer, the mode of laser rays is stabilized, and COD level is improved.

Title: Stabilization method for track bed ballast and its track construction
Inventor: NAGAFUJI TAKAHARU
IPC: E01B1/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To make the dismantling of track bed ballast easier by performing the stabilizer filling process separated into a spot-sticking filling process for combining the ballast together leaving the ballast gaps and a full filling process for completely filling the ballast gaps. SOLUTION: Leak stop layers 8, 8 are formed by spraying to the side surfaces of track bed ballast to be stabilized. Next, a stabilizer is filled, and a spot- sticking filling layer 14 connecting the ballast together at its contact portions and adjacent portions is formed. Next, a stabilizer 9c is filled by using filling devices 11, 13. Since the ballast gaps have been already become smaller by the spot-sticking filling process, the stabilizer 9c will flow down while fully filling the remaining ballast gaps, stop after a flow-down to a certain degree, and this portion becomes a boundary between a completely filled layer 15 and a spot-sticking filling layer 14. Thus, the ballast lower portion is in a spot- sticking state among the ballasts, so that the lower portion of the ballast can be ruptured with a relatively less effort during maintenance work such as the correction of deviated track or the replacement of the track bed.

Title: Ttl circuit
Inventor: TAMAMURA MASAYA
IPC: H03K19/088
Filed: 1986-02-07
Abstract: PURPOSE:To increase the fan-out number of a TTL circuit and to stabilize the input threshold voltage by providing a PNP transistor (TR) operated when a current flowing from an NPN TR of an input circuit section reaches a prescribed value and absorbing part of the current. CONSTITUTION:When the input IN is at a low level, a base current flows to the NPN TR T1 via the 2nd resistor R1. Thus, the NPN TR T1 is turned on and a collector current flows via the 1st resistor R2 and the 2nd resistor R1. When the collector current of the NPN TR T1 reaches a prescribed value or over, the base potential of a PNP TR T5 is lowered by the voltage drop by the 1st resistor R2, then the PNP TR T5 is turned on and part of the current flowing to the NPN TR T1 is absorbed. Thus, the unreasonable increase in the current flowing to the input via the NPN TR T1 is prevented.

Title: Storage circuit
Inventor: FURUYA KIYOHIRO
IPC: G11C14/00
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a storage circuit having a long durability. SOLUTION: Transistors MT, RT1, and ST0 are on, and a transistor PT0 is off. The potential of nodes STR and STC is (1/2) VCC, and the potential of bit lines BL, -BL, and -RBL is nearly VSS. VCC>VSS has been set, and electric fields toward nodes SNR and SNC are applied to ferroelectric thin films with capacitors RC and MC from the capacitors RC and MC, respectively. An electric charge is transferred in the capacitors RC and MC accordingly, and an unbalance occurs between the potential of the bit line BL and that of the bit lines -BL and -RBL. In this state, an amplifier SA is operated after the transistor ST0 is turned off. When 'L' has been stored in a cell M0, the potential of the bit line -BL becomes VCC, but the potential of the bit line -RBL does not become BCC due to a transistor ST0 being off and a polarization direction is not inverted in the capacitor RC.

The edge processing or the fill processing changes the number of times or is executed in row and column directions. Thus, characters or graphic forms can not be decoded. A data decoding part 3 decodes signals in the area stored by the private area storage part 1 by executing a processing reverse to the processing of coding.

Title: Method of forming magnetic multilayer film
Inventor: NAGAI YASUHIRO
IPC: G11B5/31
Filed: 1989-02-03
Abstract: PURPOSE:To bring a magnetostrictive constant to zero without lowering saturation magnetic flux density by using a mixed gas mainly comprising neon gas as a discharge gas for sputtering. CONSTITUTION:When argon is employed as a discharge gas for sputtering and the film thickness of a ferromagnetic layer is thinned in approximately 5nm in order to bring a magnetostrictive constant to zero, saturation magnetic flux density is lowered. When a mixed gas mainly comprising neon gas or neon gas is used as the discharge gas for sputtering, however, the magnetostrictive constant can be brought to zero even when the film thickness of the ferromagnetic layer is not thinned as seen conventional devices. Accordingly, the magnetostrictive constant can be brought to zero while minimizing the reduction of saturation magnetic flux density.
