Title: Laser oscillator
Inventor: HAYASHI EIKICHI
IPC: H01S3/0975
Filed: 1984-02-24
Abstract: PURPOSE:To fascilitate matching between a supply unit and a laser oscillator, by connecting a circuit of variable constant impendance between the supply unit and the laser oscillator. CONSTITUTION:A power supply 20 supplies three-phase current to a rectifier 12. The three-phase current is rectified by the rectifier 12 and smoothed by a smoothing circuit 14, and further converted by an inverter 16 into high-frequency alternating current. This alternating current is transformed by a high-frequency transformer 18 to have a predetermined voltage and then supplied to a laser oscillator 30. A variable capacitance capacitor 102 is connected to the secondary side of th transformer 18. The capacitor 102 is regulated in correspondence with a circuit constant on the side of the oscillator 30. That is, the resonance frequency in the secondary-side circuit of the transformer 18 is cuased to correspond to the frequency of the high-frequency power from the supply unit 100. Matching between the electric charge and the load can be thereby realized in terms of a circuit, and the oscillator 30 is enabled to be supplied with electric power effectively.

Title: Thermal recorder
Inventor: KUMAZAWA YUKIYOSHI
IPC: B41J29/377
Filed: 1987-02-17
Abstract: PURPOSE:To reduce temperature variations in a printing unit and enhance recording quality, by controlling the rotating direction of a fan correspondingly to the temperature in the printing unit. CONSTITUTION:When the temperature in a printing unit 1 is low due to a low ambient temperature or at the time of starting an apparatus, a controller 3 supplied with an output from a temperature detector 2 controls the rotating direction of a fan 4 so that air flows from the side of the controller 3 toward the printing unit 1, namely, in the direction of an arrow A. When air flows in the direction of the arrow A, air sucked in from the exterior cools a controlling unit 5 first, the air warmed by the heat of the unit 5 is blown to the printing unit 1, and is discharged to the exterior. Conversely, when the temperature in the printing unit 1 is high, the controller 3 supplied with the output of the detector 2 controls the rotating direction of the fan 4 so that air flows in a direction opposite to the above, namely, in the direction of an arrow B. Air sucked in from the exterior cools the printing unit 1 first, is then blown to the controlling unit 5, and is discharged to the exterior. Thus, the temperature in the printing unit 1 is maintained at a constant value, variations in recorded density are reduced, and recording quality is enhanced.

Filed: 1992-02-20
Abstract: PURPOSE:To obtain a highly accurate distance signal which is not affected by a part where the reflectance, etc., is different from that at its surrounding area or a slope even when the part or slope exists on the surface of an object to be measured. CONSTITUTION:Light receiving elements 2A and 2B are arranged on a sensor substrate 1 at a prescribed interval. An optical reflecting plate 3 is erected between the elements 2A and 2B. A light emitting element 4 is provided in a titled state on the opposite side of the plate 3 with respect to the element 2A. The orientation of the element 4 is set so that the light from the element 4 can irradiate the reflecting surface of an object 5 to be measured and its vicinity intersecting a plane including the plate 3 when the object 5 is in the extent of measuring distances. A distance signal is formed by performing subtraction on the output signals of the elements 2A and 2B. Since reflected light rays from nearly same positions of the object 5 are made incident to the elements 2A and 2B, the light balance between the light rays made incident to the elements 2A and 2B is not lost and a highly accurate distance signal can be obtained even when a part where the reflectance is different from that at its surrounding area or a slope exists on the surface of the object 5.

IPC: H01L21/28
Filed: 1986-02-17
Abstract: PURPOSE:To reduce resistance between electrodes, and to improve high-frequency characteristics by forming a first insulating film shaped onto the side wall of a gate electrode for an FET and a second insulating film formed onto the side wall of the gate electrode and shaped onto the upper surface of the first insulating film. CONSTITUTION:Upper and lower two-layer insulating films 20, 23 are formed onto the main surface of a substrate 11 for a field-effect transistor, and each layer is etched in succession and the first and second insulating films 20, 23 are shaped onto the side wall of a gate electrode 13. Since the first insulating film 20 on the lower side protects the main surface of the substrate 11 during anisotropic etching for leaving the predetermined insulating films on the side wall of the gate electrode on manufacture, an operating layer 12 is not damaged electrically even through anisotropic etching, and the predetermined insulating films can be shaped onto the side wall of the gate electrode 12. Accordingly, resistance between gate-source electrodes and between gate-drain electrodes is reduced, thus acquiring the field-effect transistor having excellent high-frequency characteristics.
