Title: Optical fiber for light guide
Inventor: SAWADA HISASHI
IPC: G02B6/10
Filed: 1987-04-15
Abstract: PURPOSE:To improve light receiving and emitting characteristics of light at an end face and flexibility by using a transparent resin to form a clad enclosing the outside of a core for transmission of light and providing the core having the sectional shape formed of plural pieces of circles which are respectively partly superposed on each other. CONSTITUTION:Parts where the circles are not superposed on each other are supposed to exist in the first quadrant to the fourth quadrant respectively when the sectional shape of the core 1 forming an optical fiber for a light guide is formed of 4 pieces of the circles 11 which are respectively partly superposed on each other. Then, the diameter of the core 1 is maximized at the intermediate of the X-axis and the Y-axis and is minimized in the directions of the X-axis and the Y-axis. The max. diameter of the core 1 in this case is larger than the diameter of the circular core 1 having the same sectional area and the min. diameter of the core 1 is smaller than the diameter of the circular core 1 having the same sectional area. The core 1 having the sectional shape formed by superposing of part of 4 pieces of the circles 11 on each other is, therefore, more bendable in the X-axis direction and the Y-axis direction than the circular core 1 having the same sectional area. The light receiving and emitting characteristics of light at the end face and the flexibility of the optical fiber are thereby simultaneously improved.

Title: Electrophotographic device
Inventor: ASAI ATSUSHI
IPC: G03G15/02
Filed: 1984-05-09
Abstract: PURPOSE:To obtain an image having always stable quality by changing the bias voltage to be impressed on the grid of an electrifier in such a way that the potential of a photosensitive body after uniform electrification is maintained always constant. CONSTITUTION:A photosensitive member 1 is uniformly electrified by the electrifier 3 and is then subjected to image exposing 4, by which a latent image is formed. The latent image is visualized by the developer 6 in a developing device 5. Setting of the photosensitive body 1 is detected by a microswitch 12 and a counter 13 is reset when said body is set. An integration time signal is fed from a CPU14 to the counter 13 and the integrated value is fed back to the CPU14 upon starting of the uniform electrification. A memory 15 in which a grid vias value is preliminarily stored so as to correspond to the value from the counter 13 is provided. The CPU14 compares the integrated value fed back thereto and the memory value and feeds a signal to a bias power source 11 so as to generate the voltage stored in the memory 15. The initial potential of the photosensitive body is thus maintained constant and the formation of the image having always the stable quality is made possible.

Title: Brush for small size motor and method of manufacturing the brush
Inventor: YASUDA MITSUHIRO
IPC: H02K13/00
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To prevent for generation of cracks and assure maximum application rate of material by setting the rolling trace direction to be in a direction different from that of the coil material line. SOLUTION: The rolling trace direction d of a coil material 13 is set forming the right angle with the line direction of a coil material 13 with the use of a repeated cross rolling device. Moreover, a brush 4 is blanked at the right angle to the line direction of coil material 13. The blanked brush 4 is bent at a right angle for the straight line B1-B2 as a border. Therefore, the bending line B1-B2 of the brush 4 is formed at right angles to the rolling trace direction d. Therefore, at the bending corner, cracks will not be generated. Accordingly, maximum utilization factor of material can be obtained and the rolling trace d of the coil material 12 as the raw material can be set at a right angle to the bending line of brush 4 at a low cost, so that the brush 4 having the strength such that cracks in the bending area will not occur can be obtained.

IPC: B65H7/04
Filed: 1981-06-18
Abstract: PURPOSE: To surely detect existence of feed paper, in a device with its bottom plate both for normally kick type and feed time-only kick type, by arranging an existence detector of sheets on the bottom plate integrally with a bottom plate kick member in a cassette.  
     CONSTITUTION: A through hole 12 is opened to a paper of a bottom plate 5, and a light emitting element 13 and phototransistor 14, with their light emitting and receiving fields toward the through hole 12, are fixed to the edge of a kick member 9 corresponding to said through hole 12. Accordingly, when the bottom plate 5 is kicked by the kick member 9, recording paper X on the bottom plate 5 is irradiated by the light emitting element 13, and its reflected light is incident to the phototransistor 14, then existence of the recording paper can be confirmed. In this way, since the sheet existence detector is directly arranged to the kick member at high detection accuracy without causing a suspicious effect of a quantity of light in the surroundings to reception of reflected light from irradiation light, the detector can be applied to both devices of normally kick type and feed time-only kick type.

IPC: B66D1/36
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To wind a rope around a drum in an aligned condition and to suppress early wear of a roller or the rope. SOLUTION: A roller 43 is displaced between a rope pressing position where a main winding rope 8 is pressed against a main winding drum 11 and a rope release position where the main winding rope 8 is released by providing the roller 43 on a rod 41E of a hydraulic cylinder 41 and expanding and shrinking the rod 41E. Consequently, it is possible to wind the main winding rope 8 around the main winding drum 11 in an aligned condition by displacing the roller 43 to the rope pressing position, for example, when the main winding rope 8 is wound around the main winding drum 11. On the other hand, when the main winding rope 8 is reeled out from the main winding drum 11, the roller 43 is displaced to the rope release position to avoid friction generated between the main winding rope 8 to be reeled out and the roller 43 and prolong service life of the roller 43 or the main winding rope 8.

Title: Recorder having means for preventing scattering of developer
Inventor: HIROTA KAZUHIRO
IPC: G03G15/08
Filed: 1984-05-09
Abstract: PURPOSE:To prevent the decrease in the suction force of a blower for sucking scattering toner owing to the toner sticking thereto and to enable prevention of toner staining in a device for a long period of time by increasing said suction force for certain time after the end of development of a visible image. CONSTITUTION:An ordinary rotating circuit 20 and a high speed rotating circuit 21 are provided to the blower 23 for sucking scattering toner. The circuit 20 is connected thereto in an ordinary copying stage and the blower is run at about the speed at which the developed toner is not sucked. However, a change-over switch 25 is changed over to the high speed circuit 21 by the command from a control part 24 and the blower 23 is run at a high speed for the time set by a timer 22 when the copying stage ends. Therefore the toner sticks to the suction port and duct inside and decreases blower performance if the blower is run at the ordinary speed but such sticking is obviated if the blower is run at the high speed. The toner staining in the device is thus prevented for a long period of time.
