Abstract: PURPOSE:To realize a GaAs MISFET, decrease the gate resistance, and increase the operating speed, by forming a safe nitride layer on a GaAs surface, and using CVD-W or WSiX for an electrode. CONSTITUTION:After a GaAs 1 surface is nitrided, W (tungusten) 4 or WSiX film is formed as high melting point metal gate material, thereby forming a self alignment type GaAs MISFET (Shottky gate field effect transistor).

Title: Brake circuit for actuator
Inventor: MURATA HIROSHI
IPC: F15B11/00
Filed: 1978-02-08
Abstract: PURPOSE: To greatly reduce the impact due to the stoppage of a hydraulic motor, by combining relief valves of different pressure override characteristics with each other so that a brake circuit is formed.  
     CONSTITUTION: If a change-over valve 12 is returned to a neutral state and the oil pressure in a passage 16 rises drastically, the relief valves R1, R2 open to discharge the oil pressure into a passage 15 to perform a braking action while the pressure in the passage 16 is maintained at about 140 kg/cm 2  or less. When the oil pressure has fallen below 140 kg/cm 2  due to the decrease in energy, the relief valve R1 closes first and the oil is drained into the passage 15 through only the relief valve R2. When the oil pressure has fallen further to a set level for the relief valve R2, the degree of opening of the valve R2 decreases gradually. When the oil pressure approaches 70 kg/cm 2  which is cracking pressure for the valve R2, the valve closes. Therefore, the braking action weakens gradually and then the hydraulic motor stops. Thus, the impact due to the stoppage of the motor is greatly reduced.
