Patent JP-S5957417-A (JP)
Title: Manufacture of semiconductor device
Inventor: SERIGANO MAKOTO
IPC: H01L21/74
Filed: 1982-09-27
Abstract: PURPOSE:To prevent an epitaxial layer from heaping up around an edge of an oxide layer and obtain a flat surface without a bump by a method wherein a concave whose depth is the same as that of the epitaxial layer is provided and a positioning pattern is formed on the bottom of the concave. CONSTITUTION:After a reverse conductive type buried layer 12 is formed by diffusion, a resistor film 13 is formed on the whole surface and patterned to expose a positioning pattern forming region 14. A recess 14a for a positioning pattern is formed by etching the positioning pattern forming region 14 to the depth nearly the same as that of an epitaxial layer to be grown. With a positioning pattern 15 of an oxide film left in the recess 14a, the resistor film 13 is removed and an epitaxial layer 16 is formed by epitaxial growth. Then a crown 16a is formed on the bottom of the dug down recess 14a so that the top of the crown 16a is located below the surface 16b of the epitaxial layer 16. Thus when a masking is adhered to the substrate 11 the masking is in contact with the surface 16b and kept flat so that no inferiority of the pattern is expected to exist.

IPC: F16H61/08
Filed: 1984-08-11
Abstract: PURPOSE:To reduce any shock on frictional engagement elements in a speed change produced upon releasing them by setting oil pressure of a hydraulic servo to permit it to be less than that of an accumulator for a prescribed period of time upon releasing as described above the frictional engagement elements. CONSTITUTION:Discharge resistance of hydraulic fluid from an accumulator 980, that from a hydraulic servo 920, biassing force for restoring the accumulator 980, and that for the hydraulic servo 920 are adjusted. When the hydraulic servo 920 and the accumulator 980 are acommunicated with a drain hydraulic path for releasing frictional engagement elements M, oil pressure Ps in a cylinder of the hydraulic servo 920 is set to be less than that Pa in a cylinder of the accumulator 980 for a prescribed period t1 of time. Hereby, a release characteristic suitable for the smooth release of the frictional engagement elements such as reduction of any speed change shock can be assured even when releasing them.

Abstract: PURPOSE:To obtain an ultrasonic torque device, wherein the propagating time of an ultrasonic wave is changed in response to the displacement of a piezoelectric substrate, and an ultrasonic torque measuring apparatus, which measures the torque of a rotary shaft. CONSTITUTION:Delay-line oscillators are constituted between interdigital transducers 2 and 4 and 3 and 5. Ram waves are excited between the interdigital transducers 2 and 4 and 3 and 5. A power transmission body 6 is mounted between rotary shafts 7 and 8, and the rotary shafts 7 and 8 are rotated. Then, the torsion, which is proportional to the torque difference between the rotary shafts 7 and 8, is generated in a piezoelectric substrate 1, which is provided in the power transmission body 6. The displacement caused by the distorsion is correlated to the difference in oscillated frequencies of the respective delay-line oscillators. Therefore, the torque difference between the rotary shafts 7 and 8 can be computed based on the difference in oscillating frequencies. Thus, an ultrasonic torque measuring apparatus, which has high sensitivity and can measure the torque in the broad range from the minute value to the large value, and the device used therein can be constituted.

Title: Device for preventing turnover of special vehicle
Inventor: SUGATA ASASHI
IPC: B62D6/02
Filed: 1979-12-27
Abstract: PURPOSE: To increase resistance to quick rotation of a steering wheel to prevent the turnover of a vehicle such as a container truck, whose center of gravity is high, by decreasing the quantity of pressurized oil flowing into a power steering unit when other one of voltages proportional to the speed and steering angle has exceeded each prescribed level.  
     CONSTITUTION: A voltage V1 proportional to the running speed is amplified by the output of a tachometer generator 31. The output voltage V3 of a potentiometer 35 proportional to the angle of steering is amplified. Both the amplified voltages V2, V4 are added together and then amplified to produce a potential V5. When the potential V5 has exceeded a prescribed level, an output V6 is picked up from a control circuit 40. A flow control valve 24 regulated by the output V6, etc. are used to decrease the quantity of pressurized oil flowing into a power steering unit 25. As a result, resistance to the rotation of a steering wheel 26 over a prescribed angle is increased depending on the speed when the wheel 26 has been revolved during relatively rapid motion. This leads to the prevention of the quick rotation of the steering wheel 26, which will results in turnover.

Filed: 1979-12-25
Abstract: PURPOSE:To make possible continuous casting of molten steel by adding a scorification agent to molten iron, performing oxygen blowing, and performing deoxidation by the addition of Al after refining under stirring thereby regulating O, Al and Si contents. CONSTITUTION:The molten iron which has been subjected to preliminary treatment such as dephosphorization according to need is charged into a converter into which gas can be introduced from below the bath surface. Oxygen blowing is performed by adding <=20kg scorification agent for 1 ton of this molten iron. At a suitable time during oxygen blowing and after oxygen blowing, an inert gas is introduced from below the bath surface, whereby the refining under stirring is accomplished. After the refining under stirring, the steel is tapped from the converter into a ladle while the inclusion of converter slag is being suppressed. During and/or after the tapping, Al is added and deoxidation is carried out, whereby free oxygen is regulated to <=70ppm, total Al to <=0.020%, and Si to an unavoidable contant. Thereby, continuous casting is made possible and obtaining of an ingot corresponding to a rimmed steel free from any defect such as pinholes at high yields and high efficiency is made possible.

IPC: F16J15/40
Filed: 1990-06-29
Abstract: PURPOSE:To make it possible to effectively seal the liquid at the connection section of a fixed circular pipe with a rotary pipe by providing a ring-like groove at the face of the fixed circular pipe opposing to the rotary pipe and absorbing the leaked liquid through a suction passage. CONSTITUTION:A ring-like groove 16 is formed at the center section 10b in the longitudinal direction of the insertion section of a fixed circular pipe 10, and a suction passage 18 is formed in parallel with the fixed circular pipe 10 with the opening being at the groove 16. This constitution retains the liquid going into the ring-like gap between a rotary pipe 14 and the circular fixed pipe 10 in the ring-like groove 16 for a while. The liquid flowing into the groove 16 is sucked by the suction pump 20 connected to the suction passage 18. In the delivery of the liquid between the fixed circular pipe and rotary pipe, therefore, even at the high speed rotation of the rotary pipe, effective sealing without leakage is possible.
