Title: Ultrasonic oscillator
Inventor: SAKAI MITSUGI
IPC: B06B1/06
Filed: 1981-10-16
Abstract: PURPOSE:To incerease the reciving sensitivity of an ultrasonic wave and to reduce the cost of an amplifier which amplifies the received signals as well as to improve the picture quality, by using a polymer piezoelectric material PVDF to a matching layer. CONSTITUTION:A damping layer 12 is formed on the rear side of a piezoelectric plate 11 made of a piezoelectric material and containing electrodes on both sides. Then a polymer piezoelectric material PVDF such as a PVDF film 13 which contains electrodes on both sides is provided at the front side of the plate 11 via an insulated layer 14. The pulses are applied between the electrodes of the plate 11 to oscillate an ultrasonic wave in a transmission mode. Thus the ultrasonic wave is transmitted into a subject of observation, e.g., an organism via the film 13. In this case, the film 13 functions as a matching layer to reduce the reflection occurring between the organism and the plate 11. As a result, the ultrasonic wave is transmitted with high efficiency into an organism.

Title: Pulse width modulator and pulse width modulation type switching power source
Inventor: SHIBATA KIMIO
IPC: H03K7/08
Filed: 1995-06-30
Abstract: PURPOSE: To provide a low-operation-voltage, low-current-consumption, low-noise and small-sized switching power source under fine pulse width control with specific circuit constitution. CONSTITUTION: When the output OSC CLK of an oscillator is Low, a PMOS transistor(TR) 21 short-circuits a capacitor 24 with low impedance and discharges it, so the voltage (1) of the capacitor 24 becomes VDD. The moment the CLK goes up to High in this state, the TR 21 turns OFF and a TR 22 turns ON; when the gate voltage of an NMOS TR 23 exceeds a threshold voltage, the drain current of the TR passes through the NMOS TR 22 to start charging the capacitor 24. When the capacitor 24 is charged until its voltage exceeds the threshold voltage of a PMOS TR 25, the TR 25 turns ON, its output (2) goes up to H, and the output (3) of an inverter 27 goes down to L. Then (2) and (39) are inputted and the output (3) of a NOR circuit 28 becomes the output of the modulator.

Title: Normal monitoring circuit for protective relay unit
Inventor: KAIKAWA YUKIO
IPC: H02H3/05
Filed: 1991-06-11
Abstract: PURPOSE:To eliminate inadvertent detection of defective VT, even in case of multiple fault spreading to the outside of protective section, by locking a circuit for detecting defective instrument transformer (VT) based on three-phase fault detecting conditions. CONSTITUTION:When a relay is tripped by single-phase fault of system and reclosed upon elapse of a reclose no-voltage time, it is reopened by a sustaining ground fault. A defective VT detecting/locking circuit having a route of an OR logic 9a, a NOT logic 5c and an AND logic 6d locks unnecessary response of a distance relay on condition that single open-phase prevails during no-voltage interval-and zero-phase voltage is 'present' while furthermore zero-phase current is 'not present' for no power flow. Consequently, trip lag due to unnecessary detection of defective VT caused by collapse of coordinated detection timing of zero-phase voltage and zero-phase current can be prevented when a transition takes place from unbalanced fault of internal and external successive faults to a balanced fault.

Title: Spin-coating method and spin-coating device
Inventor: FUJIWARA TAKAMASA
IPC: H01L21/316
Filed: 1990-06-25
Abstract: PURPOSE:To collect an SOG solution easily in the recessed part on a silicon substrate, and to make it possible to form an SOG film having excellent uniformity in film thickness and flatness by a method wherein a solution is dripped on a semiconductor substrate under pressure, and immediately after the dripping, a rotary coating and the like is conducted. CONSTITUTION:A solution 5a, prepared by dispersing or melting an inorganic or organic substance under pressure, is dripped on a semiconductor substrate 1, and the whole surface of the semiconductor substrate 1 is coated with the solution 5a by rotating the substrate 1. For example, an SOG solution 5a, which contains alcohol as a solvent, is dripped on the center of the silicon substrate 1 in a nitrogen gas atmosphere at the rate of 4cc per 5 seconds while the silicon substrate 1 is being rotated at 20rpm under pressure of 1.5 to 1.8 atmospheric pressure. Subsequently, the silicon substrate 1 is rotated at 2000rpm for 8 seconds, and an SOG film 5 is formed on the whole surface of the silicon substrate 1. Consequently, as the solution can be easily collected in the recessed part of the semiconductor substrate by controlling the viscosity which is determined by the speed of evaporation of the solvent in the solution, the uniformity of film thickness after the evaporation of solvent can be improved.
