Title: Semiconductor integrated circuit
Inventor: MITAKE KENJIROU
IPC: H01L21/822
Filed: 1984-11-01
Abstract: PURPOSE:To match the titled circuit with an external peripheral equipment in excellent way by adopting a low power supply voltage for a major section of the integrated circuit so as to prevent a fault due to deterioration in the dielectric strength of components and adopting a sufficiently boosted power supply voltage to a signal output section so as to obtain a sufficiently high output signal level. CONSTITUTION:MOS transistors TRQ3, Q4 are connected in series in a signal output section 8, an output signal of a main circuit section 9 is inputted in the differential system to gates 4, 5 and an output signal of the semiconductor integrated circuit is given from an output terminal 6. A voltage obtained by boosting the power supply voltage VDD of the semiconductor integrated circuit at a boosting circuit section 7, higher than the VDD is applied to the signal output section 8 as its power supply voltage. In selecting the VDD as a voltage lower than a conventional power voltage +5V, e.g., 3V, when it is boosted in the circuit to a voltage being >=+5V, the output signal level of the output terminal 6 of sufficiently over +2.5V is attained. Thus, the sufficiently high output signal level is obtained at the signal output section in this way and the circuit is matched with an external peripheral equipment.

Title: Flame spraying material
Inventor: KASAHARA HAJIME
IPC: C04B35/66
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To obtain a flame spraying material with basicity bearing a combination of adhesivity and corrosion resistance. SOLUTION: This flame spraying material is obtained by compounding 10-50 wt.% of slag with 50-90 wt.% of fused magnesia containing 1-5 wt.% of SiO2 based on chemical analysis. The SiO2 incorporation in the fused magnesia dramatically improves the adhesivity of this material in a combination of the fused magnesia with the slag, thereby fully exhibiting the effect of corrosion resistance inherent in the fused magnesia, resulting in affording this material with excellent serviceability. Furthermore, although the fused magnesia is a dense stock, the above SiO2 incorporation suppresses the texture of an object to be applied from getting excessively dense, therefore this flame spraying material is also excellent in spalling resistance.

Title: Turbomachinery and steam turbine
Inventor: GUREN YUUJIN DAIYAA
IPC: F01D21/02
Filed: 1993-09-17
Abstract: PURPOSE: To operate independently of mechanical and electrical overspeed trip systems by providing an actuator for actuating an overspeed trip system for preventing the speed of a rotor from exceeding a predetermined value. CONSTITUTION: A pressure switch 32 is installed at the discharge of an oil pump 9 that is driven by a rotor shaft 18 and that rotates at the same speed as the rotor. The discharge pressure of the oil pump 9 is proportional to the rotational speed of its impeller 12. When the pressure switch 32 senses that the discharge pressure of the oil pump 9 exceeds a predetermined value, thereby indicating that the rotor has reached an overspeed condition, it activates a trip valve 33 that causes oil to be dumped from the line supplying control oil pressure to a throttle valve actuator 6. The throttle valve 5 is spring loaded to close so that when the oil is dumped, the throttle valve 5 closes, thereby effecting a turbine trip. Thus, it is possible to operate independently of the mechanical and electrical overspeed trip systems used in the past.

Abstract: PURPOSE:To change the torsional rigidity of the whole body of a stabilizer continuously as desired by using a spring having a non--linear property for a connection rod of the stabilizer, and changing the initial flexibility given to the spring for changing the spring constant along the axis of the connection rod continuously. CONSTITUTION:For a stabilizer 21 for restricting changes A1, B1 of vertically inverse phases to each other for a wheel 22, and increasing a roll regidity R of a vehicle 23, the stabilizer 21 is connected with the wheel 22 side by a spring 24 having a non-linear property, and an initial flexibility delta of the spring 24 is set changeable. By changing the size of the initial flexibility delta given to the spring 24 continuously, the spring 24 changes its spring constant continuously corresponding to the size of the initial flexibility delta. As a result, a flexibility  x in the axial direction of the spring is changed continuously to a specified force F in the axial direction of the spring 24, and a torsion angle theta to a center part 21 of the stabilizer is changed continuously. The torsional rigidity of the whole body of the stabilizer 21 can therefore be changed continuously as desired.
