Title: High frequency fusing method of vinyl chloride sheet
Inventor: ENDO MAKOTO
IPC: H05B6/54
Filed: 1988-07-29
Abstract: PURPOSE:To strengthen the fused portion of a vinyl chloride sheet by arranging the vinyl chloride sheet to an upper electrode side and a vinyl chloride leather to a lower electrode side, disposing a Teflon tape and a high frequency cloth between the upper electrode and the vinyl chloride sheet to be fused each other at a high frequency. CONSTITUTION:A vinyl chloride sheet 1 and a vinyl chloride leather 2 to be fused eath other between upper and lower electrodes 3 and 4 are arranged and pressed to be fused by the electrodes 3 and 4 with applying a high frequency thereto. The vinyl chloride sheet 1 on the upper electrode 3 side is hardly melted, while the vinyl chloride leather 2 on the lower electrode 4 side only is melted. In this case, a Teflon tape 6 and a high frequency cloth 7 are arranged to be fused each other in order to improve the adiabathic efficiency of the upper electrode 3 to improve tensile strength of the vinyl chloride sheet 1. Proper strength of the fused portion of the the vinyl chloride sheet 1 is thus obtained.

Title: Swaging device
Inventor: UDAGAWA TEIICHI
IPC: B21J7/16
Filed: 1993-08-03
Abstract: PURPOSE:To provide a swaging device of easily working a long size bar or a wire and without requiring the heat treatment. CONSTITUTION:A roll holder 11 is haused freely rotatably on an internal wall 15 of a case 14. A spindle 16 champing a pair of dies 17 and a pair of backers 18 rotates in a speed more than a definite speed in order to generate a required centrifugal force, when rotation striking of a bar is started, the force of revolution in the same direction with the rotation direction of the spindle 16 is applied on rolls 13 inserted into roll inserting holes 12 of the roll holder 11. However, the frictional force of the rolls 13 and the internal wall 15 of the case 14 is generated, the rotation speed of the roll holder 11 is reduced than the rotation speed of the spindle 16. In other words, the action that the difference is generated on these rotation speeds is caused by rotating the roll holder 11 without rotating the material to be worked, so the damage caused on rotating the material to be worked can be reduced.

Title: Copying machine
Inventor: HANDA YASUSHI
IPC: G03B27/50
Filed: 1991-07-31
Abstract: PURPOSE:To make a smooth and accurate stop at a reference position without any time loss by correcting the speed reduction start position in scanner backward movement to an optimum position. CONSTITUTION:A control part 22 calculates the number of encoder pulses corresponding to the scanner movement distance in forward movement from paper size and copy magnifications. Then the value is set in a 1st memory as a storage area in a RAM 28 and the initial value of the speed reduction start position in the backward movement corresponding to the value is set in a 2nd memory. A motor 16 is rotated forward, then reversed on the forward movement by a necessary distance, and braked when a scanner reaches the speed reduction start position. When the scanner is reduced in speed below a target speed, a 2nd counter in the RAM 28 counts the movement time of the scanner. Then the value in the 2nd memory is corrected according to the value of the 2nd counter unless the value of the 2nd counter is within a specific range after the motor 16 is stopped so as to correct the speed reduction start position in next-time backward movement.

IPC: B29C65/64
Filed: 1986-08-18
Abstract: PURPOSE:To obtain a product, the operation of which is precise and which is excellent in durability, by a method wherein a rubber member vulcanizingly molded in advance so as to have a columnar shape, which coincides with the shape of the inner diametral part of a metal mantle, is immersed in warm surfactant and, after that, inserted in the interior of the metal mantle and finally rinsed and dried. CONSTITUTION:A rubber member having a columnar shape integrally consisting of both end portions which respectively fit to both the end opening parts of a metal mantle, and a core portion is vulcanizingly molded in advance. At the vulcanizingly molding of said rubber member, a guiding portion, which is slightly finer than the core portion and slightly longer than the metal mantle, is molded integrally in advance on the extension of the center line of the rubber member. After being immersed in surfactant, firstly, the guiding portion is inserted in the metal mantle so as to easily insert the rubber member in the metal case by grasping the end of the guiding portion in order to pull the rubber member in the metal case. After that, the unnecessary portion of the rubber member is cut off and finished. After the insertion of the rubber member in the metal case, a whole assembly is rinsed and finished. The rubber member and a metal portion closely contact with each other. In addition, the surfactant left in the contact part of both the rubber member and the metal portion has an effect to assist the bonding between the rubber member and the metal portion by heating, resulting in obtaining a product, the rubber member and the metal portion of which are more strongly bonded together with each other.

Title: Winding machine for conductor
Inventor: YOSHIOKA KENICHI
IPC: H01F41/06
Filed: 1986-08-20
Abstract: PURPOSE:To enable an adhesive to adhere uniformly on the surface of a conducter even at a high take-up speed, by providing a heating appratus for heating the adhesive within a container of an adhesive applying apparatus. CONSTITUTION:A heating apparatus 31 for heating an adhesive 5 is provided on the bottom of a container 25 through a partition 30. The container 25 receives water 32 as a heat medium in the lower portion thereof. A heater 33 is dipped in the water. The heater 33, when energized, heats the water 32 and the adhesive 5 is subjected to the heat of the water, Thereby, the temperature of the adhesive is increased, while its viscosity is decreased. When the temperature of the adhesive 5 becomes higher than a predetermined value, a temperature sensor 37 senses it and drives a take-up core driving device. A take-up core is thereby rotated so that a conductor having the adhesive thereon is wounded up on the take-up core. The adhesive 5, whose viscosity has been decreased, is thus enabled to adhere uniformly on the surface of the conductor even at a high take-up speed.
