Title: Eccentric driving device
Inventor: IZUKI HARUICHI
IPC: F16H21/16
Filed: 1980-01-10
Abstract: PURPOSE: To enable performance of a specified motion of an operating unit arranged on the same circumference with a disc cnetering around the vertical main shaft by combining an eccentric ring given as a theoretical assumed point with a slider.  
     CONSTITUTION: The rotation of the main shaft 1 makes a vertical-type bearing 10 revolve which is fixed on the same circumference on the disc 2. The foot part 16 of the lower pin of the slider 6 forms a bearing, and since the pin foot bearing 16 is constituted so that the center line thereof is perpendicular to a circular-arc surface constituting the outer-peripheral surface of the slider 6, the center line of the pin foot bearing 16 is directed constantly to the center E of the eccentric ring when the slider 6 makes circular motion in the guide groove 4 of the eccentric ring. In addition, as a horizontal arm 20 revolves, the pin foot bearing 16 also rotates spinning around the arm. Accordingly, the slider 6 integral with the pin foot bearing 16 makes circular motion in the guide groove 4 of the eccentric ring 3, while the horizontal arm 20 moves slidingly in the pin foot bearing 16 in the direction of longitude.

Title: Inspecting method of cylinder characteristics
Inventor: OGAWA KAZUHIRO
IPC: G11B33/10
Filed: 1985-01-11
Abstract: PURPOSE:To improve the rationalization of cylinder assembling operation by inspecting electric characteristics in a cylinder in the middle of a lower cylinder assembling process in response to a signal from a false signal generating substrate. CONSTITUTION:A transmitted high-frequency signal is outputted to a connector 7 for output through the electromagnetic induction coupling of a lower rotary transformer 5a and observed through a measuring instrument such as an oscilloscope to detect electric characteristics of a defect in connection between lead wires 14 and 9 in cylinders 4 and 10. Namely, when the high-frequency signal having a specific voltage level is not outputted to the output connector 7, the breaking or short-circuiting of a coil wound around a magnetic head 15, a defect in connection of a lead wire 17, or the cracking of a relay substrate 13 many occur. Thus, characteristics of cylinders for VTR are inspected without using any video tape for testing, so the inspection is performed right before the end of the assembly of the upper and lower cylinders 4 and 10 without waiting for the final assembling operation. Consequently, the productivity is improved.

Abstract: PURPOSE: To economize fuel or electric power, by reducing and recovering the thermal energy radiated from the applied brake and regenerating the recovered energy at the time of starting or acceleration.  
     CONSTITUTION: When the vehicle is retarded, clutch plates of a clutch 5 are coupled to each other first.

A piston 11 is moved right in a pressure chamber 10 by the rotation of the pinion 8 through a rack 9, thereby compressing gas in the pressure chamber 10. When the vehicle is accelerated, the piston 11 is moved left by the increased pressure of the gas in the pressure chamber 10. The motion of the piston is transmitted to the driving shaft 1 in the opposite way to the retarding process, thereby promoting the acceleration of the vehielc.
