Title: Surface emission type semiconductor laser and its manufacture
Inventor: SHINODA KAZUNORI
IPC: H01S5/042
Filed: 1995-01-30
Abstract: PURPOSE: To provide a highly efficient surface emission type semiconductor laser which has a low threshold current by preventing the dropping of the reflectivity of a reflecting mirror composed of a dielectric multilayered film at a laser light emitting hole and the leakage of laser light from the port. CONSTITUTION: In a surface emission type semiconductor laser having a dielectric multilayered reflecting mirror 10 which simultaneously covers a laser light emitting hole 12 and part of the upper surface of an electrode 8, the hole 12 formed through the electrode 8 is formed in an inverted trapezoidal shape in which the area of the hole 12 on the surface of the electrode 8 which is in contact with the surface of a semiconductor is smaller than that on the surface of the electrode 8 which is not in contact with the semiconductor. Therefore, the threshold current of the laser can be reduced and the efficiency of the laser can be improved, because the reflecting mirror composed of a multilayered dielectric film and having high reflectivity can be provided.

Abstract: PURPOSE: To realize the control of polarization without being affected by environmental change and to apply it to a printer so as to obtain a very accurate printed image by adding output from a reference polarization signal generating means to a polarization control means thereby obtaining a polarized light beam for a reference polarization signal, detecting the deviation of the polarized light beam from a specified polarization state by a polarization state detecting means and correcting it. CONSTITUTION: A polarizing means 103 is arranged between a semiconductor laser light source 101 and a rotary polygon mirror 105 and set in an initial state so as to change the polarization direction of a laser beam being the nearly linearly polarized light beam. Namely, the polarized light beam 111 is generated under the control of a polarization and light quantity control circuit 110. By arranging a half mirror 601 used as a spectrally splitting means and then polarization films 602 and 603 arranged mutually in optical cross Nicol before two photoreceptor drums 108 and 109, one photoreceptor drum is irradiated only with unidirectional polarized light beams 112 and 113. A line synchronizing signal receiving part 115 takes write start timing for every surface of the polygon mirror 105.

Title: Film unit with lens provided with built-in stroboscope
Inventor: TAKABA TETSUSHI
IPC: G03B17/02
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent glass from being scattered and flying out from a hole bored on an armor member when a discharge tube bursts with an inexpensive means by providing a barrier between the end of the discharge tube and the charge display window of the armor member. SOLUTION: The discharge tube 2 emitting strobe light is attached to a reflection mirror 3 which reflects strobe light toward a subject. In this film unit with a lens having such constitution, the charge display window is made to pierce the armor member 5 so as to view a neon tube 4 in a transparent state. If the discharge tube 2 bursts, there is fear that the broken pieces of glass at the end 2a of the tube 2 are scattered backward and fly out from the charge display window. Therefore, the barriers 1a to 1c are formed of a unit main body between the end 2a of the tube 2 and the charge display window of the member 5. Even if the tube 2 bursts and the broken pieces of glass at the end 2a are scattered, the broken pieces of glass hit against the barriers 1a to 1c and are prevented from flying out from the charge display window.

IPC: H02M7/17
Filed: 1983-01-26
Abstract: PURPOSE:To reduce the capacity of a flywheel generator and to suppress the variance of the reactive power generated when the plus/minus switching is given to the coil current, by controlling the power supply of a circulating current control thyristor only when the plus/minus switching is given to the coil current. CONSTITUTION:For a poloidal current system for experimental equipment of nuclear fusion, the power is supplied to a thyristor power supply of circulating control system from a flywheel generator in order to supply the prescribed coil currents of both positive and negative directions to a poloidal coil. In this case, a current corresponding to the circulating current standard and the actual circulating current is added to the coil current via a lower priority circuit 42 and a circulating current suppressing circuit 43 in order to ensure the smooth switching between positive and negative directions of the coil current. In this case, a circulating current control loop is utilized by an application switch 46 before and after the plus/minus switching of the coil current. Thus it is possible to reduce the electric power when the coil current is set at its maximum level and also to reduce the variance width of the reactive power.

Title: Weight display device
Inventor: NISHI KENICHI
IPC: G01G23/36
Filed: 1982-01-29
Abstract: PURPOSE:To reduce a power consumption by digitally displaying a weight of an object to be measured by means of dots of a plurality of photoconductors. CONSTITUTION:A light producer 4 consists of a light source 5, and a reflecting body 6 reflecting light emitted from the light source 5, and other ends of photo conductors 3 are positioned to the focus of the reflecting body 6. Thus, if the light source 5 is lighted by a power from the light source 7, light thereof enters through the one end of the photo conductor 3 and reaches the other end. Dots 2 corresponding to light passing through the photoconductors 3 enter to display a weight by means of numerical figures. This reduces a power consumption as compared with a device in which lamps generally used are placed in a dot manner, and besides, facilitates maintenance since a light source is only one.
