Title: Crystal oscillation circuit
Inventor: HONDA KAZUHIRO
IPC: H03B5/32
Filed: 1984-11-14
Abstract: PURPOSE:To prevent fluctuation of an oscillating frequency against the change in ambient temperature by connecting a capacitive element having a temperature characteristic cancelling temperature change of a capacitance between an emitter and a base of an oscillation transistor (TR) between the emitter and base. CONSTITUTION:The capacitive element C having an opposite temperature characteristic to that of the emitter-base capacitance of the oscillation TR Q against ambient temperature is connected between the base and emitter. The capacitive element C consists of the 1st capacitor C1, the 2nd capacitor C2, a variable capacitor V, a thermister T and a resistor R. When ambient temperature rises, the resistance value of the thermister T is decreased and a voltage impressed to the variable capacitor V is lowered, then the capacitance of the variable capacitor V is decreased, resulting that the capacitance in a series circuit comprising the 1st capacitor C1, the 2nd capacitor C2 and the variable capacitor V is reduced, and the capacitance change in the series circuit is cancelled together with the emitter-base capacitance of the oscillation TR Q.

Title: Brake control system
Inventor: ITOU TAKEHIRO
IPC: B60T8/24
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent any load from occurring in a pressure-charging pump by judging of whether there is a leakage in an inlet side gate valve or not. SOLUTION: In the case where a motor M is driven and a pressure-charging pump 8 is operated in keeping an inlet side gate valve 9 in a state of being closed intact, this pump 8 will not work at all unless there is a leakage in the valve 9 in the closed state so that no load is imposed on the motor M, whereby a motor current value becomes a lower value than the setting value after the elapse of the prescribed time from the drive starting time. In contrast with this, in the case where there is a leakage in this gate valve 9, the pump 8 will do its work so that load occurs in the motor M and the motor current value becomes a higher value than the setting value. Accordingly, the motor current value after the motor M is driven is compared with the setting value, through which a fact of whether there is a leakage in the gate valve 9 or not is judged in this way.

Abstract: PURPOSE:To suppress a change in an optical path which may be generated due to the inclination of crystal at its minimum by inclining or rotating non- linear optical crystal and matching the phases of a laser beam and the crystal to convert the wavelength of the laser beam. CONSTITUTION:When the non-linear optical crystal 1 is like a plate, the plate- like non-linear optical crystal 1 is held on an inclining device 4 set up inside a cell 3 having a laser beam incident window 2, and under the state that the cell 3 is filled with liquid 5 having a refractive index almost equal to that of the crystal 1 to be used, a laser beam 6 is made incident into the cell so that the phase of the beam 6 is matched with that of the crystal 1 to change the wavelength of the beam 6. Although the crystal in the cell 3 is inclined by the inclining device 4, the cell 3 itself is not moved. Consequently, the change in the optical path generated due to the inclination of the crystal 1 in accordance with the change in the wavelength of the laser beam can be suppressed at its minimum.

Title: Method for operating parallel plate plasma etching device
Inventor: HANADA KAORU
IPC: C23F4/00
Filed: 1994-09-08
Abstract: PURPOSE: To inhibit an increase in the temperature of a carbon electrode by stopping an introduction of a reaction gas and impression of an RF voltage, sucking an inert gas with comparatively lower temperature while introducing it to an etching chamber, and cooling the electrode. CONSTITUTION: An RF voltage is impressed on between electrodes 24 and 26, and while plasma is being generated, etching is applied to a SiO2 film on a wafer W. Next, after an introduction of a reaction gas and impression of an RF voltage are stopped and pressure is adjusted to about 2500mTorr, helium gas at a temperature of 15 deg.C is introduced to the etching chamber at a flow rate of 1.00sccm to cool the electrodes 24 and 26, and, 20 seconds later, the introduction of the helium gas is stopped. This enables the etching rate to drop at a small ratio to the number of wafers processed and each substrate to be uniformly etched even when etching is made on a multiplicity of substrates consecutively.
