Title: Electromagnetic spring clutch
Inventor: KANEHARA TOSHIHIKO
IPC: F16D27/105
Filed: 1981-07-14
Abstract: PURPOSE:To prevent an electromagnetic spring clutch from being damaged, by providing a rubber member between a flange section of an input side rotor and a part of a hub of the input side rotor on which a spring is wound. CONSTITUTION:When an electric current is passed, the input side rotor 1 magnetized to attract an armature 7. Then by the frictional force between the armature 7 and the rotor 1, the coil spring 6 is wound in the rotational direction of the rotor 1 onto the rotor hub 8 and the output side hub 5. At this time, although the rotational force of the rotor 1 is transmitted as an impact to the output side hub 5, since the rotor hub 8 is connected with the rotor flange section 1a through the cylindrical rubber member 10, the rotor hub 8 rotates together with the spring 6 wound on the rotor hub 8 circumferentially within the limit of the elastic deformation limit of the rubber member, and the rubber member 10 absorbs this impact.

Title: Switching power source
Inventor: KAWAGUCHI CHIHIRO
IPC: H02M3/28
Filed: 1981-07-14
Abstract: PURPOSE:To remove a high frequency noise generated at the switching time by providing a low pass filter between a spike voltage absorbing circuit and the primary coil of a transformer. CONSTITUTION:When an AC line side is seen from a transformer T, the impedance becomes inductance input type to high frequency noise by providing a low pass filter. Thus, since it does not advantageously produce ringing contrary to the conventional condenser input type, the high frequency noise is reduced as a whole. In this manner, since high frequency noise between the terminals a and b of a spike voltage absorbing circuit 4 is removed, noise component passing through a noise filter 1 is eliminated, thereby improving the effect of inserting the noise filter 1.

Abstract: PURPOSE:To attain a remarkably high processing speed by applying information at a changing point between a reference line and a coding line in parallel to a coding sequencer circuit and deciding the mode of coding and transiting the state in response to the mutual relation. CONSTITUTION:A coding line changing point detecting section 28 checks sequentially while shifting the coded line and when a change point is detected, a coded line changing point detecting signal 45 is generated.

Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a multi-layer clad stock capable of uniformly being heated in both a core and a skin even by the induction heating, and capable of excellently preventing generation of swelling during the extrusion. SOLUTION: An extruded billet 1 is provided with a core 3 having a cylindrical large diameter part 3a and a cylindrical small diameter part 3b. A plate of the thickness equal to the difference in radius of the large diameter part 3a and the small diameter part 3b is bent along the outer circumference of the small diameter part 3b to constitute a skin 5. The MIG welding is executed to each end of the skin 5 (a weld zone 6), and the metal to constitute the skin 5 is melted into the metal to constitute the core 3 to melt both metals to each other. No definite interface between the core 3 and the skin is present in the weld zone 6. When the induction heating is executed, not only the magnetic flux passing through the skin 5 and the magnetic flux passing through the core 3 is formed to uniformly heat the core 3 and the skin 5.  Because the skin 5 is cooled and shrunk after the welding and the clearance between the skin and the core 3 becomes small, generation of the swelling can be prevented.

Abstract: PURPOSE:To shorten the width of a bearing system by bearing the force functioning from a gear onto the input shaft by means of a bearing system where two face gears integrated on the back are journaled to the input shaft. CONSTITUTION:An inner ring 8 is secured to the folding section 6b of input shaft 6 while an annular triangular groove 8a having top angle of 90 deg. is made in the outercircumference.
