Abstract: PURPOSE:To remove an unnecessary growth layer without increasing a process, such as a process for removing a protective layer, by a method wherein after a reflection film layer is provided on the emitting edge face of a laser, bars are dipped in an etchant. CONSTITUTION:High-resistance AlGaAs layers 30A, 30B and 30C are respectively grown on the front end face, rear end face and growth surface of a laser by an organometallic vapor growth method. Then, bars are erected in such a way as to face the front end face downward and are arranged in such a way that they are made to closely adhere to each other, an antireflection Al2O3 film 32 is vacuum-deposited on the front end face, subsequently the fronts and rears of the bars are made to invert and the bars are arranged in such a way that they are made to closely adhere to each other and a high-reflectivity reflecting Al2O3/Si/Al2O3/Si/Al2O3 film 34 is formed on the rear end face by a vacuum deposition method. These bars are dipped in an etchant mixed in the ratio of sulfuric acid : hydrogen peroxide : water=2:4:100. Thereby, the unnecessary AlGaAs growth layer 30C on the growth surface is removed. On the other hand, Al2O3 layers forming the outermost layers of the films 32 and 34 are hardly etched. After this, electrodes 40, 42, 44 and 46 are formed.

Abstract: PROBLEM TO BE SOLVED: To enable a ringing choke converter to be lessened in input power at a minimum loading by a method wherein a transformer provided with a core whose gap is irregular in width is used, and a spacer is inserted into the gap of the core of the transformer. SOLUTION: A ringing choke converter is equipped with output systems, where the on-time duty factor of an inverter 8 is narrowed at a minimum loading, a non-control system 21 is gradually increased in output voltage, lessened in power consumption, and decreased in input power. That is, a ringing choke converter is equipped with a transformer where a gap between a core and a lid is irregular, and an irregular gap is provided to the center core 22 of the transformer, and the transformer where a spacer 23 of tape or film is interposed in the gap is used. A stepped part is provided to the center core 22 of the transformer. By this setup, the transformer becomes small in inductance L, so that an oscillation frequency f becomes high, the on-time duty factor is reduced, and a non-control system 21 can be lessened in output.

Title: Device for removing curling of sheet-like material
Inventor: HARA TERUHACHI
IPC: G09F3/00
Filed: 1987-03-04
Abstract: PURPOSE:To make it possible to always obtain a constant effect of removing a curling of a sheet-like material by providing a first conveying member, a second conveying member on the downstream of the first conveying member and a delay means for transmitting a variation in the rotational speed of the first conveying member to a second conveying member after delay by a predeter mined time. CONSTITUTION:When a recording sheet 1 is slackened between a first conveying member (first roller) 7 and a second conveying member (second roller) 8, a curling of the sheet 1 can be removed. Further, when the rotational speed of the first roller 7 varies, the rotational speed of the second roller 8 follows the variation after delay by a predetermined time. Accordingly, when the rota tional speeds of the rollers 7, 8 vary so that the conveying speed of the sheet 1 becomes high, the amount of slack of the sheet 1 increases. On the contrary when the conveying speed becomes low, the amount of slack decreases. Thereby, it is possible to obtain a constant effect of removing a curling of the sheet irrespective of variations in the conveying speed.

Abstract: PROBLEM TO BE SOLVED: To increase the side width of a third insulation film that remains at a side wall without thickening a second insulation film by forming a second insulation film, with the same width, on the upper surface of a second conductive film that is formed with a narrow width on the upper surface of a first conductive film. SOLUTION: A polycrystalline silicon 104 and a tungsten silicide 105 are sequentially deposited on a first oxide film 103, a second oxide film 106 is formed on the upper surface, and a second oxide film 106 and a tungsten silicide 105 are simultaneously etched and machined. Then, a third oxide film is formed on the entire surface of a device and is etched back and is allowed to remain as a side wall oxide film 108 on a side wall part of the second oxide film 106 and the tungsten silicide 105. In this case, the side width of the side wall oxide film 108 becomes the total of the film thicknesses of a second oxide film 106 and the tungsten silicide 105, thus increasing its side width without increasing the film thickness of the second oxide film 106.

Title: Spherical cyclone
Inventor: YOSHIDA YASUNOBU
IPC: B04C5/081
Filed: 1991-03-13
Abstract: PURPOSE:To miniaturize a cyclone so as to lessen the pressure loss and permit the cyclone to perform its function with a small amt. of air from an air blower by forming into a spherical form the cyclone for separating the particles suspended in a gas therefrom. CONSTITUTION:A particle-containing gas introduced by a blower from a conduit pipe 2 into a cyclone body 1 becomes a spiral gas stream moving downwards while circling around the inner wall of the cyclone body 1. During this time, the particles are subjected to the centrifugal action, moved away to the wall of the cyclone body 1, separated from the gas stream and then carried out from a discharge pipe 4 through a valve 6 to the outside of the cyclone body 1. As the spiral stream moves downwards from the center of the cyclone body, its diameter becomes smaller, the flow velocity is increased, the ascending stream is created in the center thereof and the gas is carried out from the conduit pipe 3 to the outside. Since the spiral gas stream is thus produced according to the contour of the cyclone body 1, the pressure loss thereof is small and, since a high flow velocity can be obtained at both the upper and lower parts thereof, the particles failing to separate at the upper part can be separated at the lower part.
