Title: Monitoring device of enclosing state of gas in tank
Inventor: URASAKI YASUHIRO
IPC: G01L19/12
Filed: 1991-02-20
Abstract: PURPOSE:To enable gas-enclosing state in a tank to be monitored positively be detecting an amount of displacement due to gas pressure within the tank and then comparing amounts of displacement of the tank before and after enclosing gas. CONSTITUTION:Resistance strain gauges 18-22 measure displacement according to an amount of strain of tanks 11-15 which is generated at the time of evacuation or enclosing gas of the tanks 11-15. Wheatstone bridge circiuts 23-27 obtain an amount of strain at the time of initial state, evacuation, and enclosing gas and compare the amount of strain. Further, a measuring equipment 28 electrically amplifies a change in resistance which is generated due to contraction or elongation of the resistance strain gauges 18-22 when the strain reaches a preset reference value or exceeds the reference value due to evacuation of the tanks 11-15 or enclosure of gas into the tank and then displays the indication, thus enabling whether gas is enclosed exceeding a specified pressure within the tank or not to be measured and evacuation or gas enclosing state to be monitored positively.

Title: Dry etching method
Inventor: HAYAKAWA KIYOHARU
IPC: H01L21/3065
Filed: 1984-02-15
Abstract: PURPOSE:To obtain an accurate dry etching method capable of manufacturing an LSI in a high yield by performing a stable etching at a high speed by using as guide gas mixture gas of nitrogen and hydrogen gases. CONSTITUTION:A sample 15 is disposed on a quartz plate 16 on a lower electrode 13. Nitrogen and hydrogen gases are controlled at a flow rate by mass flow controllers 17, 17', and supplied via a gas guide tube 18 into an etching chamber. The etching velocity of a resist is remarkably accelerated as compared with the case of the sole nitrogen gas merely by mixing approx. 5% of the hydrogen gas with the nitrogen gas, and to approx. 2.2 times as compared with the case of the sole nitrogen gas in the mixture gas of approx. 60% of the hydrogen gas. Thus, the etching velocity is largely improved as compared with the case of the sole nitrogen gas, and an accurate anisotropic machining without sideetching can be performed.

Abstract: PURPOSE:To avoid malfunction due to a voice and noise by transmitting another frequency signal different from a multi-frequency signal at the same time when the multi-frequency signal is transmitted and allowing the reception side to recognize a correct multi-frequency signal based on the signals. CONSTITUTION:A signal of low group frequency, a signal of high frequency and a signal of 400Hz are transmitted from a telephone terminal device T. The signal of low group frequency is inputted to a detection circuit DET via a band pass filter BPF-L, limiter LIM(L) and band pass filters BPF(L1)-BPF (L4), converted into a DC component and the result is inputted to AND gates G1-G4. Similarly the signal of high group frequency is inputted to AND gates G5-G8. The frequency signal of 400Hz is inputted to the AND gates G1-G8 via a selection amplifier circuit 3F, a band pass filter BPF and a detection circuit DETa to open the AND gates G1-G8. Thus, only when the 400Hz signal exists, the multi-frequency signal is recognized.

Filed: 1993-02-15
Abstract: PURPOSE:To control an amplitude value as equal to a set value even when the data are asynchronized with a clock by integrating an error signal from an error signal output means and instructing an amplification gain in a variable gain part. CONSTITUTION:By the variable gain part VGA 11, the amplification gain of an input signal is changed according to the instruction of a control signal 201, and the value of the gain part 11 is extracted at a previously determined interval in an extraction part 13. Then, the amplification gain of the gain part 11 is instructed so that the amplitude of the input signal 102 becomes a previously determined amplitude by a control part 11 based on the extracted value. Further, by the control part 11, the value extracted by the extraction part 13 is squared, and the error signal is outputted from the error signal output means 15a based on the squared value and a squared value just before the squared value. The amplification gain so that the signal 102 becomes a previously determined amplitude is instructed and by an integration means 18, the error signal 207 from the output means 15a is integrated, and the amplification gain of the gain part 11 is instructed. Thus, the amplitude control as equal to setting is performed even when the data is asynchronized with the clock at the time of reading the data.

Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To make a voltage detecting electrode difficult to have temperature effect due to dust or the like attached to a sensor by covering the voltage detecting electrode with an insulating film. SOLUTION: A hook-like electrode 1 is formed of a U-shaped electrode 2 with approximately U-shaped cross section and the U-shaped electrode 2 is covered with an insulating coating 3. The insulating coating 3 is formed of the insulating coating of an insulator, preferably resin, almite or the like having a drainage property for example. Also, the insulating coating 3 is formed while the U-shaped electrode 2 is provided with a hole, so that the adhesion of both electrode and coating can be increased. An electric wire for measuring voltage is mounted on the inside of the insulating coating 3 as an electric wire wiring part 4. Since the electric wire is disposed thus on the electric wire wiring part 6, and voltage shared by the U-shaped electrode 2 is supplied to a sensor part, the voltage applied to the electric wire can be measured.  Then, the U-shaped electrode 2 is covered with the insulating coating 3, so that the insulating resistance due to the insulating coating 3 is equivalently connected in series to the insulating resistance of the sensor part. Thus, the sensor part can be made difficult to be affected by temperature effect due to dust or the like attached to the sensor part.

IPC: B60W40/08
Filed: 1986-02-10
Abstract: PURPOSE:To surely stop a vehicle even though the driver leaves a manual valve from being reset in a range P and neglects the operation of a parking brake, by interlocking the output shaft of a speed change gear when no driver is in the vehicle so that the output gear may be rotated. CONSTITUTION:When no driver sits on the drive seat, a no-presence detecting means 4 delivers a signal, causing an output shaft interlocking means 5 to actuate a certain friction element 1. At this time, the output shaft 2 of an automatic speed change gear 3 is held in an unrotatable condition by interlocking, to lock wheels which are drivingly coupled to the output shaft. Accordingly, even though the driver neglects the reset of the automatic speed change gear into the range P or the operation of a parking brake, the wheels are locked to surely stop the vehicle, thereby it is possible to enhance the safety of the vehicle.
