Patent JP-S6213553-A (JP)
Title: Manufacture of magnetic material made of iron-silicon-aluminum alloy powder
Inventor: NAKAYAMA SHINKICHI
IPC: B22F3/15
Filed: 1985-07-09
Abstract: PURPOSE:To stabilize the magnetic characteristics of a magnetic material by classifying Fe-Si-Al alloy powder obtd. by a gas atomizing method and by subjecting powder whose particle size is within a specified range to HIP treatment so as to make the grains fine. CONSTITUTION:An Fe-Si-Al alloy is melted and atomized with a gas atomizer. The resulting powder is classified to prepare a powdery starting material of 30-10mum particle size. This starting material is subjected to HIP treatment under the conditions of 1,000-1,250 deg.C and 1,950atm to obtain a hyperfine-grained formed body of 20-10mum grain size as a magnetic material for a head or the like. The grain size may be further reduced to 20-5mum by extrusion. The effective width of the magnetic material is always occupied by plural grains because of the hyperfine grains, so the magnetic characteristics are stabilized.

Title: Speed change controller for transmission
Inventor: TAZAWA MITSUGI
IPC: B60K20/00
Filed: 1986-06-30
Abstract: PURPOSE:To reduce the gear noise being produced when the vehicle speed is brought to 1st speed during downshift, by employing a kickdown control solenoid for performing upshift and downshift. CONSTITUTION:When the speed is decelerated under a condition of higher than 2nd speed, a solenoid is turned off for a vehicle speed higher than second setting level through the function of a downshift control means. When the vehicle speed drops to the second setting level under this condition, the solenoid is turned on. Since a condition of lower than 2-1 speed change line has been achieved under on-condition of solenoid, 2-1 downshift speed change is performed at the time point when the solenoid is turned on. In other word, 1-2 speed change line has the vehicle speed of first setting level while 2-1(3-1) speed change line has the vehicle speed of second setting level. Since the second setting level is lower than the first setting level, shiftdown occurs immediately before stoppage of vehicle if the second setting level is set quite low, thereby the relative rotary speed of gear is low even under 1st speed condition.

Filed: 1989-06-15
Abstract: PURPOSE:To obtain a uniform film thickness stably when a semiconductor layer is grown by selectively removing an insulating film by etching so as to expose a substrate, etching the exposed surface of the substrate, and exposing the entire substrate in the atmosphere of oxygen radical or oxygen ions under the state wherein the insulating film is made to remain. CONSTITUTION:An insulating film 2 is selectively etched away by an anisotropic dry etching method, and a substrate 1 is exposed. At this time, a damaged layer 5 is formed on the exposed surface. The damaged layer 5 is removed by isotropic dry etching. A polymer layer 6 is formed on the exposed surface of the substrate 1. The polymer layer 6 is removed by exposing the entire substrate to the atmosphere of oxygen radical or oxygen ions. When the polymer layer 6 is removed, room temperature or higher is required for the temperature of the substrate in order to accelerate the effect of reaction. There is a limit for high temperature for maintaining the reliability of the substrate. In this way, the uniform film thickness can be obtained stably when the semiconductor layer is selectively grown on the substrate.
