Abstract: PURPOSE:To make an extremely strong bond, by abutting a fluorine-containing ion exchange membrane on a tetrafluoroethylene/perfluorovinyl ether copolymer membrane, placing strips of the polymer membrane on both sides of the bond portion and applying a heat sealer under a specified condition. CONSTITUTION:In the most suitable method for making a bond between a fluorine-containing ion exchange membrane and a tetrafluoroethylene/perfluorovinyl ether copolymer membrane, the ion exchange membrane to be bonded is abutted on said copolymer membrane, and thin strips, 0.05-0.2mm. thick, of the copolymer membrane are placed on both sides of the abutted portion. Then bonding is effected by a heat sealer under conditions: temperature of 200-350 deg.C, pressure of 3-20kg/cm<2> and time of 5-300sec. Even when there is a great difference between the thicknesses of the fluorine-containing ion exchange membrane and said copolymer membrane, the present process can provide a bond strength bearable to practice use.

IPC: F16H55/36
Filed: 1980-09-16
Abstract: PURPOSE: To enhance preventive effect for electrostatic charge by forming a small- sized pulley, used in a copying machine, a fascimle, etc. which utilizes electrostatic images, in porous material such as foaming plastics etc. and impregnating an electrostatic charge preventive agent in this pulley.  
     CONSTITUTION: An electrostatic charge preventive agent is impregnated in a pulley made in porous material. When polyglycol-ether (brown viscous substance with molecular value 720, specific gravity 112, solidifying point 1°C, and viscosity 675cp) is used, for example, as the electrostatic charge preventive agent, a pulley of sintered alloy with outside diameter 10mm, inside diameter 2mm, thickness 5mm, and weight 10g is placed in a depressurized room and, upon depressurization, the preventive agent is injected for impregnation. When impregnation is completed, the room shall be reinstated to normal temperature and the work taken out. According to this arrangement, a pulley impregnated with 0.01g polyglycolether can be obtained. Because this preventive agent moves gradually to the outside cirvcumference owing to the centrifugal force and then is attached to the belt, the effect of electrostatical prevention will last long.

Filed: 1989-05-24
Abstract: PURPOSE:To prevent unintentional change in the course of a car due to the braking torque difference between the left ad right wheels by sensing the braking torque difference, and controlling the aid steering angle so as to offset the yaw moment originating from the braking torque difference. CONSTITUTION:A car A is equipped with a device B for aid steering of either or both of the front and rear wheels independently from main steering on the front wheels. The braking torque difference between the left and right wheels is sensed by a means C. The aid steering device B is controlled by a means D so as to offset the yaw moment originating from the braking torque difference thus sensed. At this time, control is so made as to decrease the amount of the aid steering angle in the region where the amount of main steering is large. This prevents unintentional change in the course of the car A due to the braking torque difference, which should eliminate giving an anxious sense to the driver.
