Title: Anti-earthquake device for elevator
Inventor: SAIMA TOORU
IPC: B66B7/04
Filed: 1978-05-30
Abstract: PURPOSE: To prevent a cage and a balance weight from derailment out of rails due to deformations of the guide-rails by hanging the balance weight having a longer period of vibration than a characteristic period of vibration of a housing and providing sliding pieces and the balance weight with springs and dampers.  
     CONSTITUTION: A balance weight 15 is provided with a damper 26 and a vibration is damped quickly. If vibrating force pushing a sliding piece 19 by a guide rail 17 was given, a frame 11 will move to right through springs 20, however, due to little variation of a position of gravity center because of the phase difference of the balance weight 15 by 180, the balance weight 15 will be only pivoted in clockwise upon movement of a pin 14 to right and distances between guide rails 16, 17 are somewhat spreaded despite the pushing force between the guide-rail 17 and the sliding piece 19 is not so big. Notwithstanding, because the balance weight is pivoted in clockwise, a sliding piece 18 will be moved to right compensating the amount of the deflections of the springs 20 and the elastic deformation of the rail 17 together with reinforcing members 17AW17C.

Abstract: PURPOSE:To measure the quantity of abrasion easily with high precision by fixing a nut which is engaged threadably with a screw shaft to the nearly center part of a leaf spring, and putting the clearance between the nut and screw shaft close in one direction and returning the leaf spring to a neutral point. CONSTITUTION:An instrument is equipped with a screw shaft supporting device 2, a screw shaft rotary driving mechanism 3, a screw shaft rotational angle detector 4, a base 5, etc. Then, the nut 34 is engaged threadably with the screw shaft 9 and then fixed to the nearly center part 6a of the leaf spring 6 whose both ends are fixed to the base 5. The shaft 9 is rotated in one direction to move the nut 34 in one direction and thus the spring 6 is inflected in one direction to make a pressing force operate on the shaft 9 from the nut 34; and the shaft 9 is rotated in the opposite direction to move the nut 34 in the other direction and the spring 6 is returned to the neutral state and then inflected in the other direction. Simultaneously, the angle of rotation of the shaft 9 and the extent of movement of the nut 34 are detected and recorded. The axial clearance of a ball screw 43 is measured from the length of a blind sector wherein the nut 34 stops moving against the rotation of the shaft 9 while the spring 6 is in the neutral state.

Abstract: PURPOSE:To engage an electromagnetic clutch with no mechanical shock, in an electromagnetic clutch control circuit, by applying an initial magnetically exerting signal and an initial holding current, optimumly for each occasion even if the length of a clutch gap varies. CONSTITUTION:An electromagnetic clutch engaging signal is delivered from a main magnetically energing signal generating circuit 13, and the averaged current value just after completion of magnetic energization by an initial magnetically energizing signal S3 is automatically set in accordance with the length of the gap between an electromagnet 3 and a magnetic pole plate at each occasion so that an optimum initial holding foce is always effected. Further, the timing at which the magnetic clutch gap becomes zero is detected to control the supply of the initial magnetically energizing signal. With this arrangement, upon disengagement of the magnetic clutch no shock is generated so that the life of the magnetic clutch may be prolonged.

Filed: 1989-03-16
Abstract: PURPOSE:To easily increase the vaporization capacity of the bottom surface in a vaporizing chamber, by a method wherein spark discharge treatment is applied to the bottom surface in the vaporizing chamber and hence an oxide film is formed. CONSTITUTION:Spark discharge treatment is applied to a bottom surface 3a in a vaporizing chamber 3 and is the following. When a tungsten rod 10 is put close to a base 2, electric discharge occurs when a direct current with high voltage is applied between both of them. As a result of it, an uneven surface is formed on a base material made of aluminum with a low melting point since a part of its surface is melted, and increases a surface area thereof. At the same time, an aluminum oxide film is formed on its surface by its being oxidized in a state of high temperature and heightens hydrophilicity. In practice, in order that the bottom surface 3a in the vaporizing chamber 3 is treated in a short time, a number of the tungsten rods 10 are arranged in parallel above the bottom surface 3a in the vaporizing chamber 3 and the electric discharge is performed while they are being shifted in the directions of before and behind, right and left.

The cleaning roller 103 is press-contacted to an upper heating roller by a spring, so as to be opposed to the upper heating roller. Therefore, the cleaning roller 103 rotates linked with the rotation of the upper heating roller.

Title: Color image forming device
Inventor: FUJII HARUO
IPC: G03G15/01
Filed: 1990-03-16
Abstract: PURPOSE:To prevent the temperature rise of an image carrier and to save power consumption by transferring a color powder image on the image carrier to an intermediate transfer body, heating it every time the image is transferred, heating the superposed image from a back side and transferring it to a transfer paper. CONSTITUTION:The color powder image, for example, by yellow toner on the image carrier 3A is transferred to the intermediate transfer body 12 and heated by a heating body 15. Then, the respective toner images of magenta, cyan and black are transferred in the same way and heated every time the image is transferred. The multicolor superposed image is brought into contact with the transfer paper 20 and heated from the back side of the toner image to be transferred by changing the heating pulse width of the heating body 15. Therefore, the powder image on the image carrier is not transferred after heating the transfer body 12, so that the temperature rise of the image carrier 3A is prevented and the stable image is obtained for a long time. Since the transfer paper is not directly heated in the case of transfer, the power consump tion is reduced.

IPC: F16C9/02
Filed: 1990-03-16
Abstract: PURPOSE:To maintain necessary rigidity of a bearing of a crankshaft as well as reduce weight of a whole engine by a method wherein both a cylinder block and a bridge member are made of light alloys which have no difference in thermal expansion coefficients while a bearing cap is made of an iron alloy. CONSTITUTION:A cylinder block B being a main part of an engine is constituted of light alloy together with a bridge member 17 while a bearing cap 11 is made of an iron alloy. Thus weight of the engine can be largely reduced as well as supporting rigidity of a crank shaft Sc can be largely improved. Since the cylinder block B and the bridge member 17 are made of light alloys having no difference in thermal expansion coefficients, the difference in thermal expansion along the shaft of the crank shaft Sc can be as small as possible so that occurrence of a slant or distortion caused by the above difference in thermal expansion coefficient in each bearing cap 11 made of an iron alloy integrally interposed between the block B and the member 17 along the shaft can be efficiently suppressed. In addition,without applying excessive tightening force only to the bridge member 17, only the bearing cap 11 can be clamped to a journal wall 7 by a first coupling bolt 15.
