Title: Optical scanning device and copying device
Inventor: ITO KOJI
IPC: H04N1/04
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To enable sure reading, even when emitted light flux is not made incident directly to the eyes of user and a presser lid can not be closed by performing scanning control to a light source and a deflector for irradiating only the area, corresponding to an original size with light flux in main scanning and sub-scanning directions based on an original size detecting means. SOLUTION: A presser lid 4 for covering an original platen 3 is provided to be freely opened/closed by a hinge or the like, so that the light flux for reading can not be made incident on the eyes of a user through the original platen 3 during copy operation. Further, an original size sensor is provided as an original size detecting means and a detecting signal can be outputted for each original size (at the lower left corner of each original). Thus, control is performed, so as to irradiate only the area corresponding to the detected original size with the light flux. For the original size sensor, a light-emitting element and a light-receiving element are paired and light is emitted from the light-emitting element to the side of original platen 3 and outputted corresponding to the presence/absence of reflected light at the light-receiving element.  The light flux area is controlled by that output through a timing control circuit as scanning control means and light source control means.

Title: Clothing dryer
Inventor: NEMOTO HISAYASU
IPC: D06F58/08
Filed: 1989-11-29
Abstract: PURPOSE:To make the contact pressure between a drum belt and a motor pulley and a rotary drum uniform for preventing slippage of the drum belt by a method wherein belt ribs of the drum belt have such a middle-recessed profile that the ribs on both sides have a higher height than the ribs in the middle. CONSTITUTION:When a drum belt 4 is wound on a motor pulley 21, belt ribs 26 located inside codes 25 tend to expand in the horizontal direction (arrows C) as they receive a vertical compression strain. Therefore, the belt ribs 26 of the drum belt 4 is deformed into a middle-protruding shape, so that the contact pressure is high in the middle and low on both sides. To make such uneven contact pressure uniform, the belt ribs 26 of the drum belt 4 are made in such a middle-recessed profile 30 that the ribs on both sides have a higher height than the ribs in the middle. Thereby, uneven contact pressure becomes uniform, so that slippage can be prevented from occurring and generation of abnormal noise is diminished.

Abstract: PROBLEM TO BE SOLVED: To hold down the bending stress of a conductor bar low by forming grooves of an iron core body by stacking a plurality of electromagnetic steel plates having cutouts in the periphery and making the width of the bottom of each groove nearly the same as the width of the conductor bar to be inserted into the groove. SOLUTION: Grooves 11 of an iron core body are formed of cutouts formed at regular intervals in the peripheries of a plurality of stacked electromagnetic steel plates. The bottom of each groove 11 is formed narrow so that its width may be nearby the same as the width of a conductor bar 3 to be inserted into the groove. By a swaging method wherein after the conductor bar 3 is inserted into the groove 11 of the iron core body, the top of the conductor bar 3 is pressurized by a chisel 8, the swelling 9 is formed at the edge of the conductor bar 3 to restrict the transverse movement of the conductor bar 3 in an upper part of the groove 11. A gap 7 at the bottom of the groove 11 is small and so the transverse movement of the conductor bar 3 is also restricted at the bottom of the groove 11 as in the upper part.  As a result, the bending stress of the conductor bar 3 can be kept low and thereby the damage of the conductor bar can be reduced.

Abstract: PURPOSE:To prevent electric noises caused by fine discharging between a brush for transfer and attraction and an electrode from occurring by providing grade which gradually decreases in the moving direction of a transfer drum to the resistance value of a part of or all of the brush for transfer and attraction. CONSTITUTION:Since a part where the electrode 66a approaching to the 1st brush 78 for attraction, out of the electrodes 66, comes into contact with the 1st brush 78 first is the high resistance side 78-1 of the brush 78, electric field generated between the electrode 66a and the brush 78 is made equal to or below a discharging limit. Meanwhile, when the electrode 66a comes into contact with the brush 78 and starts sliding, charging and discharging is performed in response to the volume resistivity of the brush 78 in the sliding part and, finally, the sufficient electric field necessary for the attraction of paper is added on the low resistance side 78-2 of the brush. The grade which gradually decreases in the rotating direction of the transfer drum 42 is provided to the volume resistivity of the brush 78. Thus, the electric noises caused by the fine discharging between the brush 78 and the electrode 66 is prevented from occur ring.

Abstract: PURPOSE:To select exposure conditions intended by a photographer in flash photographing by selecting a second exposure value when the fact that it is an exposure value capable of obtaining a proper exposure is discriminated and a first exposure value when the fact that the second exposure value is not the exposure value capable of obtaining the proper exposure is discriminated. CONSTITUTION:This exposure controller for a camera is provided with a first exposure deciding means 105, a second exposure deciding means 107, a discriminating means 108, etc. Normally, the flash photographing is executed with the object luminance of the result of the photometry and the first exposure value set in advance. When the photographer shifts a program diagram to change the exposure value, the fact that the second exposure value decided based on the object luminance of the result of the photometry and the program diagram after being shifted is the exposure value capable of obtaining the proper exposure based on the guide number of a flashing device 103 and the object distance of the result of the measurement or not is discriminated. When the fact that the proper exposure can be obtained is discriminated, the second exposure value is selected and when the fact that the proper exposure not obtained is discriminated, the first exposure value is selected to execute the flash photographing.

Title: Semiconductor device
Inventor: SAITO TAKEHIRO
IPC: H05K3/30
Filed: 1986-12-27
Abstract: PURPOSE:To prevent the adhesion between a lead and resin from degrading by providing a stress absorbing section in the longitudinally intermediate part of a lead section projection from a resin package, said stress absorbing section consisting of a half etch or cutout. CONSTITUTION:In the longitudinally intermediate part of a lead part 2, a cutout part 6 or a half etch part is provided as a stress absorbing section. Even if a stress occurs in the lead part 2 when the insertion part 4 of the lead part 2 is inserted into a through-hole 22 of a print board 21 and soldered 23, the lead part 2 bends in the half etch part 5 on which the stress is concentrated, so no gap occurs between the resin package and the lead. For this, even if the angle theta of the lead part 2 is reduced and insertion is made to the print board 21, no degradation is recognized in the adhesion of the resin package 1 and the lead part 2. Also regarding the thermal expansion of the print board 21, since the stress is absorbed by the half etch part 5, the stress does not propagate to the resin package 1. Accordingly, the penetration of moisture, ionic impurities or the like from between the lead part and the resin package 1 can be prevented, whereby the moisture vapor resistance is improved and the reliability can be improved.
