Title: Dry etching device and dry etching method
Inventor: URA TADASHI
IPC: H01L21/302
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent the inferiority such as the peeling of a resist, the wire breaking, etc., caused by abnormal discharge, by suppressing the accumulation of charge on an insulating substrate by a dry etching device. SOLUTION: In a dry etching device which is equipped with an He cooling mechanism for cooling a glass board 1 and a frame-shaped clamp 2 for pressing and fixing the periphery of the glass board all around from it upper side, the clamp 2 is inclined to be thicker from the inside periphery to outside periphery so that the flow of processing gas may be performed smoothly. It is more effective, the gentler the inclination of the clamp 2 is, but it is made about 30-50 deg. because there is necessity to make it have strength so that it may not be transformed even at a temperature of about 150 deg..

Title: Antenna system
Inventor: TANIGUCHI YOSHIYUKI
IPC: H01Q3/26
Filed: 1985-09-24
Abstract: PURPOSE:To obtain an excellent reception state in a short time by swinging the beam direction of the synthesization orientation characteristic of the entire antenna by horizontally expanding an amplitude angle slowly when the reception state deteriorates. CONSTITUTION:When a receiver 42 selects a target program and detects an excellent reception state, monitoring continues. If said state is defective, the beam direction of the synthesized directivity is rotated to right by 45 deg. from an initial position 0 deg., and detects and decides the reception state. When the reception state is satisfactory, the pattern number is updated to keep monitoring the reception state. If the operation state again becomes defective, the beam of an active antenna is rotated to lelt by 45 deg. from 0 deg. in the reverse way of the former defective reception state. Then the reception state is detected and decided. When the reception state is excellent, the pattern number is updated to keep monitoring. If it is defective, such judgement is made that the incoming direction of a wave does not exist in a range of 45 deg. at both right and left sides, and an amplitude value is updated. The same action is repeated, and the beam direction of the synthesized directivity is horizontally amplified one by one, whereby the beam direction with the excellent reception state is detected.

Filed: 1991-07-26
Abstract: PURPOSE: To monitor the pressure of a gas in a cask accurately and to approach easily, for example, at the time of repairing by providing a specific gas barrier means and a gas pressure direct measuring device. CONSTITUTION: A device has a differential pressure sensor that is sealed and connected to a bore 41 through the wall of a cask that houses a potentially dangerous gas, directly monitors a gas, and at the same time becomes a first barrier between the gas and an ambient atmosphere. It has a sensor room 35 that surrounds the outer edge part of the bore 41 and a differential sensor and becomes a second barrier between gas and ambient temperature, and the sensor room 35 is evacuated partially, thus generating a pressure difference to ambient atmosphere. An absolute pressure sensor is connected to the wall through bore 41 in parallel state, thus judging whether the reduction in pressure detected by the differential pressure sensor is caused by leakage from the inside of the cask or leakage from the inside of the sensor room 35.
