Title: Piezoelectric oscillation circuit
Inventor: MATSUMOTO YOSHIAKI
IPC: H03B5/32
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric oscillation circuit where deterioration in a phase noise characteristic of an oscillated frequency can be prevented as the power supply voltage drops. SOLUTION: The piezoelectric oscillation circuit is configured to insert a coil L in series with a bias resistor (breeder resistor) to decide a base current flowing to a base of a transistor(TR). Even when the resistance of the bias resistor is designed lower as a lower voltage of a power supply is adopted, a coil L provides a high impedance to a bias resistor section in an oscillated frequency region. According to the operation above, a small circuit loss is attained and the effective Q of the oscillation circuit is not decreased, then the oscillator with excellent signal purity can be obtained.

Title: Trouble detecting device for solenoid valve
Inventor: MATSUMOTO TOKUICHI
IPC: F16K31/06
Filed: 1987-10-13
Abstract: PURPOSE:To easily detect a solenoid valve itself in its trouble by detecting a change in a riseup waveform of a solenoid valve driving current. CONSTITUTION:A waveform of driving current, applied to a solenoid 12, gradually rises once hesitating when a valve starts its opening, thereafter rises again reaching a saturation point. A hesitation phenomenon, thus generated in a riseup part of the driving current waveform, remarkably appears when a fuel injection valve 1 normally operates, but almost no hesitation phenomenon is generated when a needle valve unit 11 is disturbed in its movement by carbide or the like. In the time of trouble thus generated, the waveform of driving current smoothly rises. Accordingly, the fuel injection valve 1 can be detected in its trouble by a differentiated waveform of the driving current.

IPC: H01L21/683
Filed: 1986-10-29
Abstract: PURPOSE:To prevent a semiconductor substrate from being scattered at the time of high speed rotation thereby to make it possible to coat the substrate of undefined shape with photoresist without replacing a head of a spinner by providing a guide substrate for preventing the semiconductor substrate from being scattered around the head during rotation. CONSTITUTION:In a resist coating unit before rotation, a semiconductor substrate 1 is attracted onto a spinner head 3, a guide substrate 8 is raised simultaneously with a resist scatter preventing cover 6 to secure the substrate 1. After the substrate 1 secured with the head 3 and the substrate 8 is coated with photoresist, the substrate 1 is rotated by a driver 5 to uniformize the photoresist. After the completion of the rotation, the substrate 8 is moved down together with the cover 6, and the substrate 1 is removed. Thus, when the substrate 1 during rotation is removed from the attracting head 3, it can prevent the substrate from being scattered, and the substrate of undefined shape can be rotated at a high speed without replacing the head 3.

Title: Concentration preventive container
Inventor: TERAJIMA MASAAKI
IPC: A61J1/05
Filed: 1987-10-14
Abstract: PURPOSE:To prevent the evaporation of a solvent and the accompanying change in its concentration, by bringing the outer surface of a pipe near the upper end thereof into contact with the inner surface of the opening portion of a liquid container to such an extent as to substantially cause airtightness and by positioning the lower end of the pipe below a predetermined height of the interior of the container. CONSTITUTION:A pipe 5 in intimate contact with the inner wall of an opening portion which is sealable with a lid 2 and which is provided on the upper part of a liquid container 1 is inserted in a solution 4 of the container 1 with the lower end of the pipe 5 positioned below a predetermined height of the interior of the container. This height is smaller than that of the liquid initially accommodated in the container and selected appropriately from the amount of the liquid to be stored therein. The material of the pipe inserted into the liquid does not affect the liquid composition, preferably flexible to retain the airtightness of the container opening and, if the container is cylindrical, it is desired that the shape of the pipe be cylindrical for the intimate contact of its upper part or the adjoining portion with the container opening. This permits the area of direct contact of the solution with the external air to be reduced, so long as the pipe end reaches the liquid surface, extremely reducing the evaporation rate and accordingly preventing changes in the concentration.
