Title: External resonator type semiconductor laser device
Inventor: WAKANA SHINICHI
IPC: H01S5/14
Filed: 1984-12-18
Abstract: PURPOSE:To stabilize oscillating frequency, and to narrow the band of oscillating spectra by constituting the titled device by a semiconductor laser element, a light-emitting surface thereof is roughened, and a mirror disposed on both sides of the semiconductor laser element. CONSTITUTION:In an external resonating semiconductor laser device, light- emitting surfaces 11 formed onto the end surfaces of a semiconductor laser element 1 are roughened through a means, such as plasma etching, reactive ion etching or the like. The reflection of beams on the end surfaces of the semiconductor laser element can be reduced through the roughening. Accordingly, the resonance of beams resulting from residual reflection on the end surfaces is eliminated, thus constituting a single resonator system only by resonating frequency by an external resonator, then stabilizing oscillating frequency and narrowing the band of oscillating spectra.

Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03G15/22
Filed: 1985-11-27
Abstract: PURPOSE:To execute a copying by an optical image from the device except an original platen by turning one side of V-shaped mirrors to change an optical path in parallel, and image-forming even the light image from a screen provided at a copying machine in the turning condition to a photosensitive drum. CONSTITUTION:By turning the mirror 92 of one side of mirrors 91 and 92 to change the optical path in parallel, an optical image from a screen 65 can be image-formed to a photosensitive drum 10. Consequently, not only the usual copying by the optical image from an original platen 2 but also the copying by the optical image from a screen part 61 can be executed approximately as well as the usual copying action, and are very convenient in case of using it at a conference or the like. By turning a mirror 92 to position in the optical path to combine mirrors 93 and 150, the optical path of the external part light is secured. For such a reason, in the internal part of a copying machine 1 with a mounting density, it is hardly necessary to modify the other part such as the developer and the mounting efficiency can be improved.

Title: Laser processing device
Inventor: YOSHINO YOICHI
IPC: B23K26/064
Filed: 1985-11-27
Abstract: PURPOSE:To realize a crystal growth with a large area by adding a beam separating means which separates a shaped laser beam and adjusts the separation width. CONSTITUTION:A laser beam emitted from a laser oscillator 1 is reflected by two pieces of optical axis adjusting mirrors of a beam shaping optical system 2 and thereafter, the beam shape is enlarged by a beam expander 20. This enlarged laser beam is separated by a beam separating mechanism 21, is converged by an objective 31 of a scanning optical system 3 and is irradiated on a sample 5. In such a way, when the beam separating mechanism 21 is provided just after the beam expander 20, an incident beam 24 is separated into two beams 25 and 26, the temperature distribution of the beam spot becomes lower at the central part and becomes higher at the central parts of the left and right semilunar patterns. Thereby, the crystal growth of a semiconductor wafer advances toward the highest-temperature places of the left and right semilunar patterns and the crystal growth with a large area can be manufactured.

Title: Power circuit
Inventor: YUASA YASUHIRO
IPC: H05B6/12
Filed: 1987-10-22
Abstract: PURPOSE:To prevent the flickering of an LED on a display unit by connecting a resistor in series between the power source input side of the display unit and the output side of a main power source. CONSTITUTION:A resistor R10 is connected in series between the input side of a power source 9 for a display unit and the output of a main power source 7. The charging current to the output side capacitor of the display unit power source 9 from the output of a main power source 7 when the power source is turned on is limited, thus the rising time of the output voltage of the display unit power source 9 is delayed more than the time that the output voltage of the power source 7 on the microcomputer 4 side reaches the operating voltage of the microcomputer 4. The turning-off signal to the LED of the display unit 6 of the microcomputer is outputted before the output voltage of the power source 7 of the display unit 6 rises, thus the flickering of the LED of the display unit can be prevented.

Abstract: PURPOSE: To prevent developer from leaking through the discharge port of a developer container, to prevent a stain inside and outside the device and to attain the miniaturization of a developer replenishing device by providing a pressure reducing member for reducing the drop pressure of the developer between a replenishing part and a supply part. CONSTITUTION: A toner hopper 201 for a toner replenishing device is provided with a stirring/carrying means 301 arranged in the lowermost part inside the hopper 201, and above the means 301, a pressure reducing member 320 is arranged in parallel with the means 301 along its longitudinal direction. Further, above the pressure reducing member 320, a wire-like stirring member 322 for preventing the toner from being heaped on the pressure reducing member 320 is arranged. The stirring/carrying means 301 is driven to be rotated by a driving source such as a motor, etc., and the rotational force is transmitted to another gear through a gear, then, the stirring member 322 is driven to be rotated.  In this case, a pressure applied by the dropping toner is prevented from being directly applied on a connection port by installing the plate 322 when the toner is replenished from a toner cartridge, so that the occurrence of the toner leakage is prevented.
