Filed: 1990-02-10
Abstract: PURPOSE:To simply contract the diameter of a bush by press fitting a coupling base body having a flange provided with a plurality of wings into a bottomed annular housing having the inner diameter larger than the diameter of the extreme end of the wing and smaller then the diameter of the extreme end of the bush. CONSTITUTION:Holes 11 corresponding to the fitting holes 15 of bushes 3 of a coupling base body A are provided on the bottom 10 of a housing B. The inner diameter R0 of the housing B is formed larger then the diameter R1 of the wing 2 of the coupling base body A and smaller than the diameter R2 of the bush 3. By press fitting the coupling base body A into the housing B, the diameter R2 of the bush 3 is contracted to be R0, and elastic rubber 4 is contracted by the difference of diameters. Hereby, it can be used for a shaft coupling as it is without removing the housing, and workability for assembly of the shaft coupling can be facilitated.

Title: Overflow processing system for counter value and cell flow-in control system
Inventor: YOSHIDA KAZUHIRO
IPC: H04L47/21
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To execute the updating of an overflow flag without discrepancy in a parallel counting technique for plural counting objects (connections) such as a UPC(user parameter control) function and an NPC(network parameter control) function, etc. in an ATM(asynchronous transfer mode) exchange. SOLUTION: The updating timing of the overflow flag(OVF) to the connection Cn is indicated as a point SP in the figure. Then, a counter value tcd obtained by subtracting the value of a cell identification number (n) corresponding to the connection Cn from a global time counter value tc is defined as a local time counter value corresponding to the connection Cn . As a result, at the time tn when the counter value tc becomes the value (n) the updating processing of the overflow flag OVF is executed only for the connection Cn . Then, the cell flow-in time to the connection Cn is detected by using the local time counter value tcd obtained by subtracting the value of the cell identification number (n) corresponding to the connection Cn from the counter value tc at the point of time of the cell flow-in.

Abstract: PURPOSE:To prevent an original from dropping from an original feeding plate when an automatic original feeding device is not used, by holding the original feeding plate at a fixed position at all times without being interlocked with turning of the automatic original feeding device. CONSTITUTION:An original placed on an original feeding plate 13 is fed to an original placing plate 12 by a paper feed roll, starting with that of the lowest part. When an automatic original feeding device 10 is not used, it is held at an almost vertical position with a supporting shaft 17 set as its shaft. A side plate  18 of the original feeding plate 13 is supported by a supporting shaft 19, and a  detaining piece 25 screwed to the supporting shaft 19 becomes a state stuck to  the original feeding plate 13. A holding plate 16 and links 27, 28 constitute a  parallelogram by shafts 17, 18, 29 and 30, and an arm part 16-1 is fixed, therefore, when the automatic original feeding device 10 is turned clockwise, the  link 27 moves in parallel. The detaining piece 25 is detained by a bend part 27-1 of the link 27, therefore, the plate face angle of the original feeding plate is held as it is fixed, and there is no possibility that the original 14 drops from the original feeding plate 13.

Title: Sheet feeder
Inventor: ADACHI NOBUKAZU
IPC: B65H3/54
Filed: 1986-02-14
Abstract: PURPOSE:To prevent a sheet tip from being turned up and hitched on a device, by controlling both drive and positions of a semicircular rotor with a clutch mechanism. CONSTITUTION:When a semicircular roller 21 and a separation pad 25 are in a state of being separated, if a sheet is doubly fed as much as more than two sheets, an idler 23 and the pad 25 are frictionally contacted with each other so that the sheet at a lowermost position is separated from the sheet at an uppermost position, thus only the sheet in the uppermost position is conveyed. When the sheet is stacked on a loading block 27', since the semicircular roller 21 is stopped at a position where a straight line connecting a point (b) and a point (a) to a straight line in a sheet inserting direction (c) makes an elevation angle with the sheet inserting direction (c), the semicircular roller 21 keeps the stop position. And, if loading of the sheet is carried out in the state that the sheet loading block 27' is pressed down by a cam 30, space to be formed by the semicircular roller 21 and the sheet loading block 27' becomes widened, so that such a fear that a sheet tip is turned up and hitched on a device part will never happen.

Title: Focusing photodetector in light pickup
Inventor: INUZUKA HIDEO
IPC: G11B7/13
Filed: 1985-02-19
Abstract: PURPOSE:To obtain a focusing photodetector which has a small photodetecting area and can be attached with high accuracy, by dividing a photodetecting surface into equal four parts with an orthogonal reticle. CONSTITUTION:The optical axis of a condenser lens 20 is set in the Z direction together with axes (y) and (x) set in the vertical and orthogonal directions respectively. The (x) direction of a photodetector 240 is set in parallel with a knife edge 22, i.e., the linear edge of the photodetector 240. Here monitor signals [{A1+(-A1)}-{B1'+(-B1)}] is obtained from the outputs A1', -A1, B1' and -B1 given from elements A', -A, B' and -B respectively. In this case, it is supposed that a focused state is secured. Thus the photodetecting surface of the photodetector 240 is coincident with condensed point of the condensed luminous flux L of the lens 20. Then the photodetector 240 is displaced in the (y) direction to control said monitor signal to 0 and then in the (x) direction to control a monitor signal [{A1+B1}-{(-A1)+(-B1)}] to 0 respectively. Here the spot of the flux L is set accurately at the center of the photodetector 240. Under such conditions, the photodetector 240 is fixed and the width W and the height H of the photodetector 240 are decided by the edge 22 and the lens 20. In such a way, the photodetector 240 can be miniaturized and attached easily.
