Title: Base body member for surface-worked electrophotographic sensitive body and production thereof
Inventor: KOIKE ATSUSHI
IPC: G03G5/10
Filed: 1987-12-23
Abstract: PURPOSE:To provide the title member having an effect of preventing interference fringes by dropping rigid balls having a specific surface shape by gravity or forcibly from a prescribed height to bring the balls into collision against the surface of the base body to be worked, thereby forming ball-shaped trace dents. CONSTITUTION:The rigid balls 15 are carried by plural ribs 16 projecting from the inside wall of a container 14 and are transported by rotation of the container 14 to the upper part of the container, from which the balls are dropped onto a cylinder 11. The rotating speed as well as the diameters of the cylinder 11 and the rotating vessel 14 which holds the rigid balls 15 are adequately determined and controlled by taking the density of the trace dents to be formed, the supply rate of the rigid balls, etc., into consideration. The rigid balls 15 transported while being stuck to the container wall drops to collide against the cylinder at the time of the adequate rotating speed when the rotary container 14 is rotated. The trace dents are then formed on the surface of said cylinder and ruggedness is generated. The member for the base body formed in such a manner has the extremely high image performance when an electrophotographic photoreceptive layer is formed thereon as an electrophotographic sensitive body, more particularly an electrophotographic sensitive body for lasers. The marked effect of preventing the interference fringes is thereby obtd.

Title: Square sealed battery
Inventor: HOSHINO KOICHI
IPC: H01M2/08
Filed: 1993-12-22
Abstract: PURPOSE:To protect a safety valve from heat produced by welding and surely weld a sealing body by making a gasket lover than the upper surface of a cover, making a rivet higher than the cover, and making a gas escape path higher than the cover. CONSTITUTION:A sealing body 3 is fit to an opening end of an outer jacket can 1 and laser-welded. Since the upper surface 11a of a gasket 11 is lower than the welding surface, when a long side surface 1a of the can 1 is welded, melt caused by radiation heat and reflected heat of laser beams can be prevented. Since the upper surface 12c of a rivet 12 is higher than the welding surface, entrance of heat of the laser beam from a cut-out part 8c of a cathode cap 8 is suppressed. Heat generation caused by melting of a gasket 11 does not occur. A safety valve incorporated in the cap 8 is protected when the sealing body 3 is welded, operating pressure is stabilized, and high reliability is provided. Since gas containing soot is not produced from the safety valve, laser beams are not blocked. Therefore, the sealing body 3 is surely welded to the whole circumference of the can 1.

Title: Continuously variable transmission
Inventor: BABE TOMOKI
IPC: F16H63/06
Filed: 1989-12-14
Abstract: PURPOSE:To make an automatic variable transmission possible and a speed change similarly possible, even when an input shaft is rotated in both normal and reverse directions, by displacing a speed change ring in a direction of the axial center by means of a cam, having a tilt surface on the end face, and by means of a spring for displacing the cam in accordance with a load of an output shaft. CONSTITUTION:When a load is applied to an output shaft 26, turning force in proportion to load torque is transmitted from a cone 32 to a speed change ring 38 so as to try to rotate a cam 39 in the circumferential direction with the ring 38. Then the cam 39 is rotated in the peripheral direction, so that a tilt surface 49 pushes aside a ball 41 against tension of a spring 45, and displaced in a direction of the axial center so as to separate from a fixed retainer 43 while compressing the spring 45. Consequently, a contact position of the ring 38 with the cone 32 is displaced to its skirt, and in a position where pressing force of the tilt surface 49 to the ball 41, based on the load torque, is balanced with force of the spring 45 increased by the displacement of the cam, speed change ratio in accordance with a load is obtained by stabilizing a mechanism. Also, because the tilt surface 49 is provided with tilt parts 50, 51 in mutually reverse directions, a similar automatic speed change can be performed even when an input shaft 21 is rotated in any of both normal and reverse directions.

Title: Portable massage device
Inventor: YOUNG JAMES V
IPC: A61H1/00
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a portable massage device which reduces vibration transmitted to user's hand. SOLUTION: The portable handy massage device for medical treatment 10 includes a vibrationless motor 20 which has an output axis 64 directly connected with a vibrator head assembled body 14. Rotating movement of the output axis 64 is converted into a vibration orbit movement around the shaft's center line in the vibrator head assembled body 14 by an offset cam formed as a part of an eccentric material with a balance weight. The balance weight provided with the eccentric material reduces vibration transmitted to a user's hand and insulates vibration of the vibrator head assembled body 14. The installing structure between vibrating adapter parts and the still part of the vibrator head assembled body 14 fixed with the motor 20 prevents the vibrator head assembled body 14 from rotating unnecessarily.

Title: Connecting method for bnc terminal
Inventor: KOIDE JINICHI
IPC: H01R43/00
Filed: 1989-12-15
Abstract: PURPOSE:To employ an automatic inserting machine so as to rationalize connecting processes for a BNC terminal, by soldering a short jumper, that is, a U-shaped wire lying across a square hole, to the printed circuit board and then soldering the cut jumper wires respectively to the BNC terminal. CONSTITUTION:A BNC terminal 2 is fastened onto a jack plate 1 with a nut 3, while a short jumper A is automatically inserted into a printed circuit board 4 to be soldered. The soldered jumper A is cut at its part corresponding to the central part of a square hole B in the board with a nipper, and then the cut jumper wires are positioned respectively at two terminal heads of the BNC terminal to give soldering 5 respectively to their intersecting points. The accurate installation of the BNC terminal is thus made unnecessary to make positioning of the BNC terminal unnecessary. Also because the insertion of the short jumper into the printed circuit board is simply carried out, the number of connecting processes for the BNC terminal can be rationalized.
