Title: Speed detecting device of rotating body
Inventor: ISHIDA HIROSHI
IPC: G01P3/42
Filed: 1984-03-09
Abstract: PURPOSE:To reduce errors of a speed signal caused by a variation of a power supply voltage by feeding back an output of a specified photodetector to a light emitting element through an error amplifier. CONSTITUTION:A fixed slit plate 2 opposed to a code plate 1 provided with a slit on the whole periphery has slits 211, 221 and a window 23. the window 23 has a large width, and depending on a rotation of the code plate 1, the brightness of light from a passing light emitting element is not varied. Photodetectors 311, 321 and 33 are provided on a fixed photodetecting plate 3. In this state, elements 311, 321 which have photodetected light from the light emitting element through the slits 11, 211 and 221 in accordance with rotation of the code plate 1 generate a sine wave-shaped electric signal, and it becomes a speed signal proportional to a rotating speed. Also, an electric signal generated by the element 33 which has photodetected the light through the window 23 is not varied by the rotation, and affected only by a power supply voltage. Therefore, when this signal voltage is fed back to the light emitting element through an error amplifier, the brightness of the light emitting element becomes constant even if the power supply voltage is varied, and a current flowing to the light emitting element can be controlled so that an output of the element 33 becomes constant.

Title: Field effect transistor
Inventor: SAKAMOTO RYOJI
IPC: H01L21/338
Filed: 1994-03-15
Abstract: PURPOSE:To achieve a high drain withstand voltage by adding inactive impurities to the region between a gate electrode and a drain electrode on the surface of a semiconductor substrate thereby lowering the field in the vicinity of the drain electrode. CONSTITUTION:Si<+> ions are implanted into the surface of a GaAs semiconductor substrate 1 to form an n<-> layer 7. AuGe and Ni are then deposited and alloyed by lift-off method to form a source electrode 3 and a drain electrode 4 making ohmic contact with the substrate. Similarly, Al is deposited by lift-off method to form a gate electrode 2 making Schottky contact with the substrate. Subsequently, inactive impurity ions are implanted using the electrodes 2, 3, 4 as a mask in order to form a deep level. The inactive impurity includes oxygen ion, iron ion, and carbon ion. Since the distance between the gate electrode and the drain electrode can be lengthened substantially, the field is lowered in the vicinity of the drain electrode and thereby the drain withstand voltage can be increased.

Abstract: PURPOSE:To form a uniform pattern irrespective of time difference of laser radiation by setting a temperature state at the time of laser irradiation to a relatively low temperature state in which nuclei are generated without thin film growth, and then raising the temperature to glow a thin film. CONSTITUTION:After a semiconductor wafer 4 is placed in a vessel 1, the vessel 1 is evacuated, and simultaneously heated. The heating temperature is set to a lower temperature than that for growing a thin film by thermal decomposition and at which the wafer 4 itself becomes 180 deg.. Then, raw gas G is supplied into the vessel 1, laser light 6 is introduced into the vessel 1 through a window 8, and the laser light 6 is radiated on a plurality of places set on the wafer 4. Nuclei which become the base of forming the thin film are formed by this laser radiation. Thereafter, the wafer 4 itself is heated to the temperature for growing the thin film in a state that gas G is flowing, and the thin film is grown for a predetermined time. Thus, the temperature is enhanced, and the thin film is simultaneously grown on the laser radiated part in a step of growing the thin film, thereby eliminating an irregularity in the thin film forming state due to the time difference of the laser radiation.

IPC: F24F13/22
Filed: 1988-02-26
Abstract: PURPOSE:To prevent water drips from splashing out of a main body case by a method wherein dew receiving plates having upper portions more widely spaced apart from a rear suction port than that of lower portions are arranged between a heat exchanger within the main body case and the lower portions of a rear surface suction port, and lower ends of the dew receiving plates are arranged substantially at the same height as that of the lower end of the rear suction port. CONSTITUTION:Water drips of drain water dripped from a sub-drain pan 8 are blown off rearwardly by an air speed of an air flow passing below a heat exchanger 6 and carried to a rear surface panel 1a. The water drips strike against a dew receiving plates 12, drop onto the drain pan 9 positioned below it and then are discharged to a proper location out of the main body case 1. Thus, it is possible to prevent a floor surface on which the main body case 1 is mounted from being wetted and fully wetted with water. Since the dew receiving plates 12 are arranged such that their upper portions are spaced apart widely from a rear surface suction port 3 than their lower portions, the air stream struck against the dew receiving plates 12 is guided smoothly to the rear lower portion of the heat exchanger 6 and then the air sucked from both suction ports 2 and 3 is guided to the heat exchanger 6 without having any trouble.

IPC: F16B31/02
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a torque nut which can prevent damage of a screw thread by preventing excessive screwing-in of a nut and can be reused. SOLUTION: A receiving claw 18 is protrusively arranged on an outer peripheral surface of a nut 12 screw-fitted to a bolt. A sliding contact surface 18B obliquely rising in the screwing-in direction of the nut 12 from an outer peripheral surface of the nut 12, is formed on the receiving claw 18. A pushing claw 32 deflectable to the outside is protrusively arranged on an inner peripheral surface of a cover 22 rotatably installed on the nut 12. An inclined face 32B to come into contact with the sliding contact surface 18B is formed on the pushing claw 32. When the cover is rotated in the arrow A direction, the inclined face 32B pushes the sliding contact surface 18B, and torque is transmitted to the nut 12, and the nut 12 rotates. When the torque exceeds a prescribed value, the pushing claw 32 deflects, and gets over the receiving claw 18, and the cover 22 idly rotates, and prevents damage of a screw thread. Since the pushing claw 32 is elastically restored, a torque nut 10 can be reused.
