Title: Piston with saved front surface area
Inventor: TAKAHASHI ISAO
IPC: F02F3/00
Filed: 1991-01-17
Abstract: PURPOSE: To improve combustion efficiency by extending top lands on both side parts of a piston upward. CONSTITUTION: A piston 3 in an engine is formed into a shape wherein top lands 1 on both sides of the piston project upward from a head gasket in the top dead center by extending the top lands 1 on the part upward in order to eliminate recessed parts on both sides of the piston. Moreover, a combustion chamber 4 is so formed as to match the shape of the piston 3. In the piston 3 including a cylinder, the front surface area on the combustion chamber is decreased, so as to improve combustion efficiency. Moreover, combustion pressure can be efficiently converted to axial output by decreasing gas leakage from the recessed parts on both sides of the piston.

Title: Semiconductor device and manufacture thereof
IPC: H01L21/336
Filed: 1992-03-30
Abstract: PURPOSE:To enable a semiconductor device to he lessened in capacitance between a gate electrode and a source electrode and enhanced in withstand voltage even if the lateral diffusion length of a source region is longer than the lateral length of a mask base. CONSTITUTION:As a source region 5 is made to diffuse in a lateral direction by doping starting from the outer end of the base of a mask 10, an overlap of the source region 5 with a gate electrode 7 is reduced in length by the material length of the base of mask 10. Furthermore, as a gate insulating film 8 is formed thick at the ends of the gate electrode 7, a vertical distance between the source region 5 creeping under the gate electrode 7 and the gate electrode 7 located above the region 5 increases. A semiconductor device of this design is enhanced both in operation speed by lessening it in capacitance between the source region 5 and the gate electrode 7 and in withstand voltage by protecting the gate insulating film 8 against damage caused by the concentration of an electrical field on the end of the film 8.

Title: High-speed data output system
Inventor: HIROSE OSAMU
IPC: G06F13/00
Filed: 1980-05-30
Abstract: PURPOSE: To shorten the overhead time of a CPU by writing data, which contains an added discrimination signal with a shorter period than a reference signal, in the memory buffer of a data output equipment and by retrieving it by a microcomputer.  
     CONSTITUTION: The CPU20 of a computer body 10 writes data with a discrimination number for a synchronizing signal in data tables DT12 and DT14 at the timing of a reference signal having a longer period than the synchronizing signal by costant times. A buffer memory BM26 in a data output equipment 24 is commanded by the CPU20 to read the DT12. The computer 10 accepts a reference signal as interruption one to generate a DT16 where the DT12 was. The equipment 24 retrieves the contents of the BM26 which corresponds to a synchronizing signal with a synchronizing signal from a microcomputer μCM30 triggered by the reference signal and, when the synchronizing signal and discrimination number coincide with each other, sends the data in the BM26 to read the data in the DT14 into a BM28 under the command of the CPU20. Consequently, the computer 10, only when inputting the reference signal, processes a batch of the data in the DTs in a short time and at a time.

Filed: 1990-03-23
Abstract: PURPOSE:To secure the vibrationproof effect with the simple structure by connecting the first and second supporting metal fittings by the rubber elasticity and charging the inside of the first chamber with low viscosity fluid and charging the second fluid chamber with the high viscosity fluid and installing a bevel member which spreads at right angle in the vibration input direction in the first fluid chamber and also installing an action part in the second fluid chamber. CONSTITUTION:When vibration is inputted into between the first and second supporting metal fittings 12 and 14, the interval of a thin gap part 60 in the second fluid chamber 40 varies, and high viscosity fluid 44 flows in reciprocation at right angle in the vibration input direction, and a shear stress proportional to the speed is generated, and a damping force is developed. Since the shearing stress is proportional to the area of the thin gap part 60 and inversely proportional to the interval, the damping effect for the low frequency vibration can be developed by adjusting the interval of the thin gap part 60. In the first fluid chamber 38, the low viscosity fluid 42 flows in reciprocation in the vibration input direction in a throttle passage 50 by the shift of a bevel member 42, and the low dynamic spring effect is developed on the basis of the resonance action of the low viscosity fluid 42. The low dynamic spring effect can be developed for the high frequency vibration such as confined sound by adjusting the ratio between the sectional area of the throttle passage 50 and the length.

Filed: 1981-05-19
Abstract: PURPOSE:To reduce processing manhours substantially and also improve anti- vibration and insulative properties, by forming an insulative resin layer within and around a bare rectangular conductor coil and thickening a side of coil axis direction. CONSTITUTION:A hetero-shaped insulative resin coating 7 of thermoplastic and thermohardening is formed around a bare flat conductor 6 sectionally rectangular. The hetero-shaped coating 7 has a thin film on the radial side (shorter side) between coil layers, and a thick film on the axisl side (longer side) in contact with coil attachment. A coil 4 is formed by winding wire 5 in approximate ring shape. The insulative coating 7 of thick film acts as buffer to fix the coil. It contacts between the inner circle of a yoke and a magnetic pole piece. This contacting force prevents each layr and terminal of the coil 4 from moving. This improves the anti-vibration and insulative properties, and reduces the processing manhours substantially.
