Title: Winding method
Inventor: TAKADA KOUJI
IPC: H01F41/08
Filed: 1983-02-21
Abstract: PURPOSE:To reduce the cost of a die and suppress the noise and avoid the damage caused by a rotation trouble by a method wherein a separated bobbin is fitted to a magnetic body or a core which has no air gap in its magnetic path and the bobbin is coupled to be solid and the winding is performed by fixing one end of the winding wire and rotating the bobbin by mounting a belt on it. CONSTITUTION:A bobbin 2, separated beforehand, is fitted on a core 1 and the separated bobbin is made solid by adhering or coupling and one end of a wire wound on the bobbin is fixed to the bobbin. A belt 4 is put on the bobbin and a roller 5 which drives the belt and is connected at one point. This connection 6 can be disconnected. The wire is wound by driving the belt. The cost of a die can be reduced compared to the winding method using gears. Because of this belt-driing method, noise is suppressed even if many winding machines are driven in parallel. If the bobbin is not rotated smoothly during the winding, the bobbin is not damaged because the belt slips.

Abstract: PURPOSE:To correct the offset of the web and the flange of an asymmetric steel shape for the purpose of obtaining the product steel shape in the aimed size, by  specifying the roll size for the shape reforming mill to be installed successively to the universal mill. CONSTITUTION:In an asymmetric H-beam 40 on the run-out side of the universal mill, the leg length B1 of the upper thin-walled flange 40 is made longer than the leg length B2 of the lower thick-walled flange 50.

As a result, by adjusting the roll gap E to a range not to reduce the thickness of the web 46, the leg length B2 of the lower flange 50 is made nearly the size A2 and the leg length B1 of the upper flange 40 is made nearly the size A1 in order to equalize the leg lengths of upper and lower flanges.

Title: Rotational difference sensing joint
Inventor: NIIKURA YASUHIRO
IPC: F16D31/02
Filed: 1992-02-17
Abstract: PURPOSE:To prevent the lowering of torque by setting the sliding face hardness of a driving piston lower than the hardness of a cam face for making the driving piston perform its stroke. CONSTITUTION:When relative rotational difference is generated to a housing 4 and a rotor 2, the outflow of oil discharged to an accumulator chamber 90 from a cylinder chamber 60 in association with the reciprocating motion of an axial driving piston 50 is regulated by an orifice 8 so as to generate fluid pressure in the cylinder chamber 60. The driving piston 50 is pressed to a cam face 31 by the force of cylinder internal oil pressure so as to generate joint transmission torque corresponding to the relative rotational difference between the housing 4 and rotor 2. When the cam face 31 is worn, the piston stroke becomes small, the piston speed is reduced, and the joint transmission torque is reduced, but since the sliding face hardness of the driving piston 50 is set lower than the hardness of the cam face 31, the cam face 31 is hardly worn. The lowering of torque can be thereby prevented even with the wear of the driving piston 50.

At the same time, if a flaw detection pulse is transmitted through an excitation circuit 12, the transmitting vibrators of the transmitting-receiving vibrators 2 are excited, by which ultrasonic waves are transmitted. The reflected waves thereof are then received and are inputted to a receiving circuit 13, by which the presence or not any flaw is judged. Hence, the number of required cable cores of the signal transmission cable 7 is reduced to 4.
