Filed: 1990-09-13
Abstract: PURPOSE:To suppress blowing and suction of an engine at the time of transmission by providing a second control valve which increases a flow rate of operational oil discharged from an actuator of a releasing side frictional element when a hydraulic pressure in one hydraulic circuit exceeds a specified value. CONSTITUTION:A spool 31 of a drain valve 30B on a hydraulic circuit of a drain side is moved leftward against a spring 32 according to a difference between a hydraulic pressure in an oil passage 4A and a modulator pressure Pm, accompanying with increase of a hydraulic pressure of an applying side, since the hydraulic pressure in the oil passage 4A is applied to a hydraulic chamber 5 of an applying side actuator 1A as a pilot pressure through an oil passage 38A. When the applying side hydraulic pressure reaches a specified value, ports 34 and 35 of the drain valve 30B are communicates with each other. Operation oil in the hydraulic chamber 5 of a drain side actuator 1B is then discharged all at once through the drain port of the drain valve 30B. The hydraulic pressure on the drain side is abruptly decreased and frictional elements of the drain side are released.

Title: Heat treatment
Inventor: MATSUMOTO YOSHINARI
IPC: H01L21/324
Filed: 1987-09-25
Abstract: PURPOSE:To improve the reproducibility such as the activation rate of the implantation layer or the activated carrier concentration distribution by a method wherein the heat treatment of a III-V compound semiconductor wafer on which a film for preventing the thermal surface decomposition is deposited is performed in a plasma containing nitrogen atoms. CONSTITUTION:By performing a heat treatment within a plasma containing nitrogen atoms such as a NH3 plasma, a nitride of the constituent atom of a III-V compound semiconductor is produced on the coating film surface. Once the nitride is produced, the diffusion of the constituent atom of the III-V compound semiconductor into the coating film is suppressed and the activation process of ion implantation stabilizes. By applying this heat treatment, the variability of the element characteristics among wafers and within a wafer becomes small when MESFET's are fabricated. Further, also for the case that they are fabricated with the timing of the process being shifted, element characteristics are obtained the variability of which does not exceed the scatterings among wafers and within a wafer.

Title: Reference voltage generating circuit
Inventor: YOKOYAMA AKIO
IPC: G05F3/22
Filed: 1984-11-16
Abstract: PURPOSE:To secure a satisfactory transient responce by connecting the 5th transistor between the input part at a side of a differential pair and a circuit power supply, and supplying a transient current to said transistor when the circuit power supply is supplied. CONSTITUTION:The 1st and 2nd current sources I03 and I04 are connected to the emitters of the 1st and 2nd collector earthed transistors TR T2 and TR T3 using a reference DC potential 1 as a common base. While the bases of the 3rd and 4th TRT3 and TR T4 (differential pair) having the 3rd current source I03 connected to a common emitter are connected to each other. Then the 5th TR T5 is connected between the input part of one of the paires TR T3 and TR T4 and a circuit power supply. Thus a reference voltage generating circuit is obtained. The output voltage V0 does not reach its final level until a capacitor C0 is charged immediately after a power supply is switched on. Thus the base potential VB3 of the TR T3 is smaller than the base potential VB4 of the TR T4, and a current I03 of a constant current source 6 flows to the collector of the TR T4. Then no current flows to the TR T5 after the volt age V0 reaches its final level. Thus it is not required to increase the 1st current source I02.

Abstract: PURPOSE:To prevent interfering noise due to a coupling capacity and to perform high-speed operations of a large operating margin by fixing the two bit lines arranged adjacent to a bit line at precharging potential when the data of a memory cell are read out to the bit line. CONSTITUTION:When, for example, a memory cell M3 is read out, a word line WL0 and dummy word line DWL0 become 'H' levels. Accordingly, signal charges of the memory cell M3 and a dummy memory cell DM3 are respectively read out to a bit line BL2 and the inverse of BL2. The read-out signals are amplified by means of a sense amplifier SA2. During the period of the sense amplification, bit lines BL1, the inverse of BL1, BL3, and the inverse of BL3 adjacent to the selected bit lines BL2 and the inverse of BL2 are fixed at precharging potential. As a result, no interfering noise comes to the selected bit lines from the adjacent bit lines and high-speed operations of a large operating margin can be performed.
