Title: V-belt driven automatic speed changer
Inventor: KIMURA SUKEAKI
IPC: F16H9/12
Filed: 1983-12-22
Abstract: PURPOSE:To enable the reduction ratio in a low range to be set to a large value, by leaving the diameter of a V-pulley, which suspends a movable face approaching to a certain extent to a fixed face, as slightly spread even under the condition of centrifugal force not acting by a centrifugal weight. CONSTITUTION:A compression spring 12, being resiliently mounted between a movable face 7 and a ramp plate 10, can be compressed to a position where the maximum reduction ratio is provided by separating the movable face 7 to a maximum from a fixed face 6, and this spring in its free length L1 is set to a position approaching a little distance to the fixed face 6. Accordingly, the movable face 7, when it is stopped, is placed in a position such that a V-belt 8 provides the reduction ratio a little smaller than that in a low range.

Title: Method for shearing metal plate preventing sagging and step difference thereof
Inventor: IKUSHIMA KOICHI
IPC: B21D28/24
Filed: 1990-09-13
Abstract: PURPOSE:To prevent a metal plate from sagging or generating step difference by making the backup component in contact with the rear side of a metal plate to be worked, coining it by a prescribed amount with a punch having a knife like blade, next removing the backup component and continuously advancing the punch. CONSTITUTION:At first, a plate holder 18 is pressed to the rear side of a metal plate 16, the metal plate 16 is clamped between the plate holder 18 and a die 15. A punch 12 is pressed to the metal plate 16, the coining is executed by forcibly pressing the knife blade of the punch into the metal plate 16 by a prescribed amount. When the punch is forcibly pressed in the metal plate 16 by executing the prescribed coining, and the coining is finished, the plate holder 18 is removed, an other dies 15' of the shape corresponding to the dies 15 comes in contact with the rear side of metal plate 16, and the metal plate 16 is clamped. Next, the metal plate 16 is punched out by using the punch 12. Because of continuously punching with the same punch, the step difference is not generated at the shearing contour line of product surface. And because of coining, the punched hole circumferential edge part to be essentially sagged is replenished preliminarily with the material, so the sagging is not generated, very good shearing contour line without the sagging and the step difference can be obtained.

Title: El panel construction for light source
Inventor: MIMORI KENICHI
IPC: B41J2/44
Filed: 1987-09-25
Abstract: PURPOSE: To increase the signal-to-noise ratio and improve the reliability by forming a through hole in the center of a light-transmissive substrate and coating the flank of the substrate, the inside of the through hole, and a light emission body with a light shield film. CONSTITUTION: The light from the light emission body 12 is converged by the convex lens type light transmissive substrate 11 and reflected by a document surface A. The reflected light passes through the through hole 13 formed in the substrate 11, and is converged by a condenser lens 14 and sent to a light receiving element 15. The light from the document surface, on the other hand, only passes through the condenser lens, so scattering and absorption are small and the substrate 11 and light emission body 12 are covered with a black light shield film 17, so no scattered light is mixed with signal light. Consequently, the signal-to-noise ratio becomes large and the reliability is improved.

Title: Copying machine
Inventor: ITO MASAZUMI
IPC: G03G21/00
Filed: 1987-09-25
Abstract: PURPOSE:To shorten the waiting time and to save power consumption by modifying the reading sequence in a copying mode stored by memory, calling the copying mode that an operator has preferentially registered beforehand through one key operation and copying originals. CONSTITUTION:In registering preferential programs, when a preferential program registration key 97 is turned on, mode program currently selected and set in memory is registered as preferential program. When a key 95 is turned under a status that all LEDs 95a-95c are turned off, a flag F is set owing to the turning-off of the LEDs 95a-95c and the registration of preferential programs. Then said programs discriminate either of memories A-C, and the mode programs stored in the discriminated memory are set. Thus, preferential program is initially set by one key operation to attain a coping-enabled state, thereby the waiting time can be shortened and power consumption is saved.
