Abstract: PURPOSE:To prevent a trap of hot carriers affecting a drain at the position of a spacer oxide film in a field effect transistor having a low concentration drain region structure (LDD structure) by forming a thermal oxide film having less trap level on the low concentration drain. CONSTITUTION:A polycrystalline silicon is grown on a gate oxide film 2 to form a gate electrode 1, and with them as masks for an ion implantation low concentration impurity phosphorus ions are implanted to form a low concentration diffused region 5. Further, the whole surface is oxidized to form a thermal oxide film 4 on a spacer. Then, a vapor growth oxide film 3 is formed on the film 4 to form a spacer oxide film. Then, it is so anisotropically etched as to completely etch the oxide film off the electrode 1 to form the spacer oxide film made of the films 3 and 4 on the sidewalls of the electrode 1 and the film 2. Thus, even if hot carriers are generated to be invaded underneath the spacer oxide film, the oxide film on the drain is formed of the thermal oxide having a less trap level and accordingly not trapped.

Abstract: PURPOSE:To prevent an overvoltage exceeding a rated voltage from being applied on a motor, by providing an output voltage regulating circuit which controls an inverter output voltage when the output of a solar battery exceeds a load capacitance. CONSTITUTION:Normally, a device is controlled so as to set the ratio of the inverter output voltage V to an inverter output frequency (f) constant (V/F constant control) invariably to maximize the output voltage of the solar battery by an inverter control circuit 6.

IPC: F15B9/09
Filed: 1988-11-28
Abstract: PURPOSE:To accurately perform flow control even under vibration by providing a guide valve to control communication between ports through its rotary drive inside a housing. CONSTITUTION:An input electric current is applied to coils 12, 13 to give magnetic polarity to an armature 11, and magnetic attracting force and repulsive force between the armature 11 and pole pieces 18 minutely rotate the armature 11 with a line D as an axis. Since the upper end of a pilot valve 31 is fixed to the armature 11, its rotating angle equals that of the pilot valve 31. When the pilot valve 31 rotates counterclockwise by the angle of theta, the edge parts 75a, 75b of the valve 31 decreases the opening area of nozzles 38a, 38b respectively, and its edge parts 76a, 76b conversely increase the opening area of nozzles 39a, 39b respectively. Pressure in pressure chambers 41a, 41b therefore increase, and that in pressure chambers 42a, 42b decrease to generate pressure difference between the pressure chambers 41a, 41b and those 42a, 42b. A rotary type guide valve 100 is thereby rotated counterclockwise to stand still at a position where the pressure difference disappears.
