Title: Image forming device
Inventor: TAYA YOICHI
IPC: G03G21/04
Filed: 1990-07-06
Abstract: PURPOSE:To improve operability by providing a detection means for detecting that a counting means is mounted in a device main body and a control means for initializing various functions based on the detection output of the detection means. CONSTITUTION:A key counter 55 functioning as the counting means for counting the times of forming images in an image forming part 11 is provided in the device main body 1 so that it can be attached/detached through a short connector part. The terminal of the device main body 1 is connected to a detection terminal P1 functioning as the detection means for detecting he mount state of the key counter 55 in the device main body 1. By mounting the key counter 55 in the device main body 1, various functions for setting the number of copied sheets, copying density and copying magnification, etc., are automatically initialized, and the device is in a state where copying can be performed. When it is demounted from the device main body 1, the device gets in a state where copying can not be performed. Thus, errors in copying actions in a state where the initializing operation is forgotten are prevented, and the new initializing operation is not needed, thereby improving the operability.

Title: Malodor prevention in petroleum vaporizing burner
Inventor: MIYAHARA KINGO
IPC: F23N5/24
Filed: 1984-08-27
Abstract: PURPOSE:To prevent the malodor at ignition and extinguishment by a method wherein a fuel is changed-over to a petroleum after the generating of alcohol vaporized burning at an igniting time, then the petroleum fuel is changed-over sequentially to a alcohol fuel at an extingushing time. CONSTITUTION:An alcohol is fed into the inner periphery of a vaporizing cylinder 8 from an alcohol fuel pipe 15. After keeping the steady burning condition of an alcohol vaporizing burning, the feeding quantity of the alcohol fuel is decreased sequentially, the petroleum fuel supplying quantity is increased sequentially instead of the alcohol fuel via a petroleum fuel pipe 14. When an extinguishment, is required the feeding quantity of the petroleum from a petroleum fuel pipe 14 is decreased sequentially, the alcohol fuel supplying quantity from the alcohol fuel pipe 15 is increased sequentially instead of the petroleum fuel, finally, changed-over to the alcohol fuel. Thereby, the malodor generated at the ignition and extinguishment can be prevented.

Title: Conveying method of crushed ice
Inventor: HAYASHI TAKESHI
IPC: F25C5/02
Filed: 1980-12-15
Abstract: PURPOSE: To reduce thawing loss of crushed ice, by conveying crushed ice using low-pressure-and-high-speed air flow by sucking air in a pipe from discharge side of a conveying pipe through an air-blowing step, and also by conveying the crushed ice using cooled air sucked in from a separate conveying pipe.  
     CONSTITUTION: Suction side of an air-blowing step 3 is connected through with discharge side of a conveying pipe 1, and air being lower in pressure than atmosphere is made to flow at a high speed in the conveying pipe 1 through this air- blowing step 3, and by this air flow the crushed ice sucked into the conveying pipe is air-conveyed, and at the same time, the air-blowing step 3 forcibly introduces cooled air from a discharge gate 6 into a separate conveying pipe for conveying the crushed ice further. As the crushed ice is conveyed by the low-pressure-and- high-speed air flow produced by insulation expansion of air taken into the conveying pipe from atmosphere, the air is cooled and a difference in temperature between the air in the conveying pipe 1 and surface of the crushed ice becomes reduced, and therefore, thawing loss of the crushed ice being conveyed can be minimized.

Title: Wiring board, manufacture of semiconductor device using it and mounting method thereof
Inventor: YAMAGUCHI EIJI
IPC: H01L23/12
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent the top of an opening from being covered with a solder electrode and improve the life of connection between the semiconductor electrode and an electrode pad by extracting a part of the opening circumference to the outer side of the outer periphery of the electrode pad. SOLUTION: A wiring board 1 has an electrode pad 2A whose surface is exposed from two openings 4A formed on a protection film 3A on a mounting face, and a spherical solder electrode 6 is connected to the surface of the electrode pad 2A. A part of the circumference of the opening 4A is extracted to the outer side of the outer periphery of the electrode pad 2A. Thus, when a solder electrode 6 is arranged on the surface of the electrode pad 2A, the circumference of the opening 4A extracted to the outer side of the outer periphery of the electrode pad 2A does not contact the solder electrode 6, and the top of the opening 4A is not covered with the solder electrode 6. Therefore, at the time of connecting the solder electrode 6 to the surface of the electrode pad 2A with activator, since the vaporized activator is discharged outside not to be left in the opening 4A, no void is generated in the solder electrode 6.

Title: Semiconductor laser
Inventor: IKUWA YOSHITO
IPC: H01S5/00
Filed: 1990-07-03
Abstract: PURPOSE:To obtain a semiconductor laser in which characteristics are not varied during energizing and a visible light is scarcely deteriorated by composing of a disordered active layer and a pair of clad layers in which forbidden band widths for holding the active layer are wider than that of the active layer and an impurity concentration is lower than that of the active layer. CONSTITUTION:A disordered active layer 3 and a pair of clad layers 2, 4 in which forbidden band widths for holding the layer 3 are wider than that of the layer 3 and an impurity concentration is lower than that of the layer 3 are provided. In this case, since the Ga0.5In0.5P active layer 3 is formed in a completely disordered state, the state is not varied during energizing. Since the layer 3 has p-type carrier concentration equivalent to threshold value carrier density necessary to generate a laser oscillation, recombination of electrons and holes occurs between a conduction band and an acceptor level. Since the state density of an acceptor order is smaller than the state density of a valance band, light absorption of the layer 3 is reduced, and scarcely deteriorated. Thus, a laser in which characteristics are not varied and scarcely deteriorated, is obtained.

Abstract: PURPOSE:To prevent cargo from colliding or from being damaged by providing the inside of a rubber-lined roller with ratchet claws so that the ratchet claws engage with a ratchet wheel when the roller speed exceeds the speed of the ratchet wheel driven at a constant speed. CONSTITUTION:A ratchet wheel 8 is driven with a sprocket 11 and a chain 18 at a constant speed. Cargo drops on a rubber-lined roller 5 of a roller conveyor. Here, when the cargo dropping speed exceeds the speed of the ratchet wheel 8, the ratchet wheel 8 engages with a ratchet claw 10 so that the roller 5 is braked. As a result, cargo is braked by the friction between the lining rubber of the roller 5 and collision is prevented.

Title: Light pickup device
Inventor: MATOSAKI TOSHIYA
IPC: G11B7/09
Filed: 1988-07-18
Abstract: PURPOSE:To relax acceleration received from an external part and to improve a tracking servo property by injecting a magnetic fluid into a magnetic circuit part between a magnetic void for control and a coil for control. CONSTITUTION:A magnetic fluid 10 is injected into a void between a focusing coil 7 fitted to the lower cylindrical part of a lens holder 5 and a permanent magnet 3. With a constitution, the magnetic fluid 10 can always stay at the void by the act of a magnetic field, and when strong acceleration is received from and external part, the most part of rapid motion due to the clearance of a holder 5 bearing part and a supporting shaft 4 is absorbed by the viscosity of the magnetic fluid 10. Moreover, since the flux of a magnetic circuit passes through within the magnetic fluid 10, flux density is increased. Consequently, the servo property of a device can be improved inexpensively.
