Title: Semiconductor integrated circuit
Inventor: MIYAMOTO HIROSHI
IPC: H01L29/78
Filed: 1987-08-07
Abstract: PURPOSE:To speed up operation and improve an operating margin, by using a first MOS transistor of a second conductivity type formed on a semiconductor substrate of a first conductivity type as a first type MOS transistor used in a circuit structure in which a source potential is increased. CONSTITUTION:First and second MOS transistors having different impurity concentrations on an effective semiconductor substrate 1 are used, as a first type MOS transistor Tb used in a circuit structure in which a source potential is raised and a second type MOS transistor Ta not existing in such a circuit structure. Therefore, by setting respective impurity concentrations at predetermined values, it becomes possible to reduce gates in the second MOS transistor and to prevent the decrease in a threshold voltage and the breakdown strength between source and gate and also prevent the increase in the threshold voltage due to the increase in an effective coefficient of the substrate in the first MOS transistor. As a result, operation can be speeded up and an operating margin can be improved.

Title: Molding of slip casting
Inventor: KOJIMA KOICHI
IPC: B28B1/26
Filed: 1989-07-31
Abstract: PURPOSE:To obtain a ceramic molding having thin and thick intricately shaped wall parts in a simple process under such control as to prevent generation of cracking by forming and drying a coating film on the thin wall part of a slip molding. CONSTITUTION:A coating is applied to the thin wall parts of a separated slip molding to form a coating film-covered molding. The thin wall part of the slip molding is covered with coating material such as rubber or resin solution by immersion, spraying or coating. Preferably, the thickness of the thin wall part to be coated is at most about 1/4 that of the thick wall part. Even if differences in thickness between the thin and thick wall parts are smaller than the aforesaid value, the coating film on the thin wall part is made possible by proportionally coating the thin wall part, thereby preventing the occurrence of cracking. As organic coating material for forming the coating film, resins such as polyacrylic acid, polyvinyl alcohol and polyvinyl butyrale, styrene- butadiene rubber, diene rubber, silicone rubber and urethane rubber are used.

Title: Amplitude control circuit
Inventor: SONODA YUTAKA
IPC: H04N5/52
Filed: 1989-07-31
Abstract: PURPOSE:To prevent a ringing from being generated in an output signal by suppressing an output signal level of a feedback loop when a signal level of a control signal is changed stepwise largely. CONSTITUTION:A response speed regulating circuit 31 of logarithmic transformation circuit configuration is interposed between a comparator circuit 23 and an integration circuit 25 in a feedback loop FB. When a change in the signal level of a control signal S2 is large, the circuit 31 decreases a rate of change in the signal level of an regulated output signal beta. As a result, the response speed of a coefficient signal SK obtained from the integration circuit 25 is decreased. Thus, even when a change in the signal level of the control signal S2 is excessively changed stepwise, no ringing is generated in an output signal S3.

Title: Facing milling cutter
Inventor: OOISHI SADAO
IPC: B23C5/06
Filed: 1981-12-10
Abstract: PURPOSE:To prevent the generation of cutting vibration and chattering by holding a work through a work pressing member to which the turning effort of a cutter body in a facing milling cutter is not transmitted.

Title: Hydraulic controller for belt type continuously variable transmission for vehicle
Inventor: KONO KATSUMI
IPC: B60W10/10
Filed: 1986-08-26
Abstract: PURPOSE:To obtain the simple device and reduce the power loss of a hydraulic pump by selectively outputting the higher cylinder oil pressure among the primary and secondary cylinder oil pressures by a selecting valve and allowing the first pressure adjusting valve to perform the pressure adjusting operation by the cylinder oil pressure and to output the first line oil pressure higher by a prescribed pressure. CONSTITUTION:The higher cylinder oil pressure among the primary and secondary hydraulic cylinders 26 and 28 is selectively outputted by a selecting valve 90. The first line hydraulic pressure higher by a prescribed pressure than the cylinder oil pressure is outputted by allowing the first pressure adjusting valve 48 to operate the cylinder oil pressure outputted from the selecting valve 90 and perform pressure adjusting operation. Therefore, the need of a microcomputer and electromagnetic pressure adjusting valve for pressure-adjusting the first line pressure is avoided, and the device is made simple. Further, since the first line hydraulic pressure is adjusted on the basis of the actual cylinder oil pressure, setting of the first line hydraulic pressure higher than the hydraulic pressure estimated from the propulsion force characteristic is eliminated, and the power loss of a hydraulic pump 42 can be reduced.
