Title: Method and device for rolling gear while making backlash part
Inventor: GOU JIYUNICHI
IPC: B21H5/02
Filed: 1978-07-21
Abstract: PURPOSE:To roll a gear with high accuracy, by alternately and strongly pushing the intermediate parts of both strands of a chain extending from one master gear to another to perform rolling and burnishing simultaneously. CONSTITUTION:When a toothed workpiece W is thrusted between the master gears 4, 4', the workpiece keeps rotating between the master gears. Pushing the intermediate part of the forward strand of the chain 10 downward by a push roller  15, the surface A of a tooth 21 of the workpiece W is brought into pressural contact  with a tooth 22 of the master gear 4 so that a backlash part is provided on the surface A of the tooth 21. Pushing the intermediate part of the backward strand of  the chain 10 upward by a push roller 16, the tooth 22 of the master gear 4 is  brought into pressural contact with the surface B of the tooth 21 of the workpiece  W and a tooth 22' of the other master gear 4' is rotated in pressural contact with  the surface A of another tooth 21 of the workpiece so that the surfaces A, B of the  teeth are burnished. The gear W having the teeth 21 with the surfaces A, B well  balanced to each other is thus rolled.

Title: Noise-proof device for vehicle for vehicular chain transmission gear
Inventor: ISHIKAWA YOSHIMI
IPC: F16H55/30
Filed: 1994-04-27
Abstract: PURPOSE:To reduce noise caused by the collision of the teeth of a sprocket at the chain winding side with each roller of a chain in the vehicular chain transmission gear. CONSTITUTION:Both the side surfaces of the base section 3 of each tooth 2 of a sprocket 1 are made to be each flat surface 32, and many lateral holes 4 are provided for the base section. Paired elastic rings 7 brought into contact with both the side surfaces are integrally combined with each other so as to be held by the sprocket 1 at each joint section. When the chain 10 is wound in the sprocket 1, each link 12 is hit against each elastic ring 7 so as to allow shock to be absorbed, each roller is then meshed with each tooth 2 thereafter. Since each elastic ring 7 is not restricted at any place other than each joint section, strong material which is liable to be deflected and can withstand impact load, can favorably be used.

CONSTITUTION:As for a developing unit, a cam 26 rotates by a signal of development ON, a developing device body 25 is allowed to ascend to a developing position, and the developing surface 25A is opposed adjacently to the image holding surface 21A. Subsequently, a pump 28 operates and a circulation is started so that a liquid toner is sucked up from a toner tank 27, flows between the developing surface 25A and the image holding surface 21A, collected by a toner collecting part 25b, and returns again to the toner tank 27.

Title: Storage battery
Inventor: KITAMURA MASAKI
IPC: H01G11/56
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To aim at safety of a storage battery as well as setting its capacity to a high level by providing porous separators for holding electrolyte as well as determining intervals between positive and negative electrodes and decreasing the porosity of this separator from the positive electrode side to negative electrode side. SOLUTION: An irregularity state is provided on the pole surface of a negative electrode 1 and the porosity of a separator 2 is reduced as closer to the negative electrode 1. Namely, the inside diameter of an air hole 3 is reduced as approaching to the negative electrode 1. Therefore, the resistance near to the surface of the negative electrode 1 side of the separator 2 becomes larger than the resistance along the irregularity shaped interval between the separator 2 and the negative electrode 1. Thereby, owing to the movement of positive electric charge from the positive electrode toward the negative electrode 1 inside of the air hole, the surface on the negative electrode 1 side comes in a rate limiting step so that the electric current distribution is uniformalized without any local overcharging and the charging capacity can be increased safely. This device acts usefully as a part of a portable electronic apparatus.
