Title: Liquid growth method for semiconductor material
Inventor: MAEDA SHIGEO
IPC: H01L21/208
Filed: 1992-01-29
Abstract: PURPOSE:To prevent the deep fiduciarity from being formed due to the contamination of Si dopant in the light emitting layer by depositing an epitaxial layer containing Si dopant on a substrate, and by depositing an epitaxial layer which does not contain any Si dopant after contacting the substrate with a solution for crystal growth containing no or almost no Si dopant. CONSTITUTION:A growth material is heated, and cooled gradually to a temperature to begin depositing an Si-doped GalnP layer 2. Then, a slider 13 is moved to allow a GaAsP substrate 1 to contact with a melt in a solution reservoir 11a. In the melt, the Si-doped GaInP layer 2 is grown. When this epitaxial layer is grown in an appropriate thickness, the slider 13 is moved to allow the GaAsP substrate 1 to pass the lower part of the solution reservoir 11b. At this time, a melt containing the Si dopant is diffused in the melt in the solution reservoir 11b, and at the same time, a cleaning layer containing no or almost no Si dopant is deposited in an amount of approximately 1mum or less. As a result, it is possible to prevent any deep fiduciarity from being formed due to the contamination of the Si.

Title: Spheroidizing treatment of hypereutectoid steel
Inventor: SETO KAZUHIRO
IPC: C21D8/02
Filed: 1989-02-22
Abstract: PURPOSE:To spheroidize a lamellar carbide in the structure of a hypereutectoid steel, to improve the workability and to prevent defective hardening and the deterioration of the toughness at the time of heat treatment by successively subjecting the steel to hot rolling under specified conditions, cooling, coiling, cold rolling and heat treating under specified conditions. CONSTITUTION:A hypereutectoid steel contg. >0.8wt.% C has pro-eutectoid cementite as a network carbide and pearlite consisting of lamellar cementite and ferrite. Since the structure of the steel brings inferior workability and causes defective hardening and the deterioration of the toughness at the time of heat treatment, spheroidizing is carried out as follows: the steel is hot rolled at >=720 deg.C finishing temp., cooled at >=30 deg.C/sec cooling rate in the temp. range of 720-600 deg.C, coiled at 600-450 deg.C, cold worked at >=30% working rate, heated to a temp. between the A1 transformation point + 50 deg.C and the Acm transformation point and held for 30-600sec. The network and lamellar carbides including hard brittle cementite are finely spheroidized and the toughness and workability of the steel are improved.

Title: Reduced speed sensor
Inventor: SUGIMOTO TOMIJI
IPC: B60R21/00
Filed: 1986-02-27
Abstract: PURPOSE:To generate a signal for a long period by forming an air intake with a nonreturn valve in the peripheral wall of a guide wall and admitting outside air in the space in the guide path behind a sensing mass when the sensing mass contacts an output contact. CONSTITUTION:A reduced speed sensor 1 is fitted to a vehicle body so that a cap 4 is in the running direction of the vehicle; and the sensing mass 9 is held by a magnet 10 during a normal run in contact with the rear end surface 8 of the guide path 6. If the car body is reduced greatly in speed owing to a collision, etc., the mass 9 moves forth with an inertial force in the running direction. At this time, the gap between the mass 9 and the inner peripheral surface 3a of the guide path 6 is small, so air is compress in the space in front of the mass 9 and negative pressure is produced in the space behind it, so that the forward movement of the mass 9 is attenuated. Then when the mass 9 contacts 14 and 15, the air intake 16 communicates with the space in the guide path 6 behind the mass 9 and the nonreturn valve 17 is opened to admit the outside air as shown by 16. Consequently, the mass 9 keeps on moving forward and the contact state of the mass with the contacts 14 and 15 is held sufficiently long, so that the signal is generated for a long period.

Title: Automatic transmission for vehicle
Inventor: TOMOMATSU HIDEO
IPC: F16H61/28
Filed: 1990-02-20
Abstract: PURPOSE:To miniaturize an automatic transmission by constituting a gear train so as to set a specified shift step with a combined pattern of plural sorts of engagement and release of a friction engaging means. CONSTITUTION:A control unit consisting of a hydraulic controller C and an electronic control unit E sets a shift step on the basis of running conditions, but as to the shift step where there are plural sorts of engagement and release patterns, it selects such a pattern that engages a friction engaging means (second clutch means K2) equipped with an accumulator 7 and executes a speed change, if possible. To be concrete, the first gear speed is set in advance after engaging clutches K1, K4, and K5 and a brake B1, by way of example, and when shift to the second gear speed is judged, the clutch k2 is engaged but the clutch K4 is disengaged. At this time, timing for engagement is optimized by the accumulator 7. Likewise, even when shifting from the third gear speed to the fourth one, the clutch K2 is operated. Therefore the number of accumulators becomes lessened.

When the address exists, a key data storage part 29 is accessed, and when no address exists, a main storage part is accessed, and the main storage key is stored 29, and is registered in the array 26. When either address extended bits 21 is (1) and the key access is performed with the address of more than 2GB, all (0)s are selected 24 as the low-order 4 bits by the output of an OR circuit 23, and thenceforth, the same operation as the one within 2GB is performed. By such operation, it is possible to perform buffer management with a single key address array in a system having two kinds of storage protection units simultaneously.
