Patent JP-H04130659-A (JP)
Title: Semiconductor integrated circuit
Inventor: KANEDA RYOHEI
IPC: H01L27/088
Filed: 1990-09-20
Abstract: PURPOSE:To restrain an increase of a GND potential by a method wherein the input time constant of a discharge transistor or the output time constant of a predetermined gate is made greater. CONSTITUTION:A unit 20 is located around a central portion of a substrate and contains a precharge circuit 23, and a unit 21 having an output function of data to a bus line 22 contains a discharge circuit 24. A NOR gate (for instance, G0) is connected to a discharge transistor Tn0 through a resistance element R0. The input time constant is determined by an input resistance component and a gate capacitance component of a transistor, and herein the input resistance component is increased by the resistance element R0. If the change rate of a gate potential is made small as described above, the change rate of the transient current of a discharge transistor can be restrained, an increase of the GND potential due to the inductance component of the GND system can be restrained.

Filed: 1994-09-12
Abstract: PURPOSE: To make it possible to install and fix a discharge outlet storage box to a hydrant valve without touching at the time of installation by putting both side faces of this box into an open state. CONSTITUTION: This discharge outlet storage box consists of three broken down parts; a right side face lid upper 2-2, a right side face lid lower 2-3 and a left side face lid 3 in order to put both side faces of the box into the open state. After the discharge outlet storage box is installed and fixed, the right side face lid upper 2-3 is installed from below an iron pipe and the right side face lid upper 2-2 is installed from above this ion pipe. Both are fixed to the main body by a rivet. The left side face lid 3 is fixed by the lever to the left side face of the main body. The discharge outlet storage box is used by turning over the box 180 deg. in the case of a left side face piping.  The procedures are diametrically opposite from the procedures in the example of the right side face piping: The right side face lid lower 2-3 is commonly used as the left side face lid lower, the right side face lid upper 2-2 as the right side face lid upper and the left side face lid as the right side face lid.

Title: Thread fastening device and thread fastening method
Inventor: HANAWA YASUHIRO
IPC: B25B23/14
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To prevent a position gap between a case and parts, by reversing the directions of rotation of a driver to which a power is transmitted from one output shaft of a differential gear mechanism and a driver to which a power is transmitted from the other output shaft. SOLUTION: Bevel gears 20, 23 are rotated through output shafts 11, 12 by rotation of bevel gears 18, 19, and bevel gears 22, 25 are rotated following the rotation to thereby rotate drivers 5, 6 and fasten threads 3, 4. In this case, even if the difference occurs between torques of the two drivers 5, 6, a larger power is transmitted to the driver having a smaller torque, and thread fastening is executed so that the difference between the torques of the two drivers 5, 6 will disappear. Additionally, as the drivers 5, 6 are rotated in the different directions respectively, frictional forces generated between the threads 3, 4 and an optical part 2 work with the same magnitude in the respectively compensating directions relative to the thread 3 and the thread 4 to thereby enable to reduce a position gap between a case 1 and the optical part 2.

Title: Microphone
Inventor: ISHIKURA AKIRA
IPC: H04M1/00
Filed: 1990-09-21
Abstract: PURPOSE:To improve S/N by common-mode rejecting voice signals outputted from a second microphone from the signals outputted from a first microphone, and outputting the obtained signals as transmitting signals. CONSTITUTION:Impulsive noise components included in the transmitting voice signals outputted from the first microphone 3 and the impulsive noise components outputted form the second microphone 4 are almost at the same level and phase, because the first microphone 3 and the second microphone 4 are provided almost at the same position towards a switch 6. Thus, the impulsive noise components included in the transmitting voice signals outputted from the first microphone 3 are canceled by the impulsive noise components outputted from the second microphone 4. As the result, the transmitting voice signals whose impulsive noise components are reduced can be outputted. Thus, the S/N can be improved.

Abstract: PROBLEM TO BE SOLVED: To efficiently use a system band without impairing the quality of a sound signal by converting digital information emitted from a mobile object communication network at a first data rate into a second data rate required in a position where an ATM exchange is connected to a public switched network for the first time. SOLUTION: A mobile terminal 10 calls a cable system telephone set S1 in the public switched network 200.
