Title: Vibration preventing device
Inventor: NIIHORI TAKEYOSHI
IPC: F16F15/073
Filed: 1981-01-14
Abstract: PURPOSE:To prevent the generation and propagation of vibrations, shocks and the like by a method wherein the frictional force between leaves in a laminate leaf spring mechanism is controlled in accordance with the conditions of a body to be supported. CONSTITUTION:In the case where the body (a) to be supported is, for example, a machine which moves a hammer up and down, a controlling part 20 feeds a  control from a hammer position detecting part fitted to the body (a). For example, a cylinder device 17 is extended at the moment the hammer strikes a die  or the like, whereby an upper end part of a clamping member 12 is rotated  outwards and a pressure applied to the leaf springs 2 between an arm part 13  and a base 7 is reduced so that the clamping force becomes zero. As a result,  the leaf spring mechanism 1 is moderately bent to absorb the shock. Then, when the hammer is moved downwards together with the die or the like which it has  struck, he cylinder device 17 is drive controlled so as to gradually increase the  clamping force. Accordingly, excess displacement can be prevented by the gradual increase in the frictional force in the bending stage of the leaf spring  mechanism 1.

Title: Preparation of coil spring made of fiber reinforced plastic
Inventor: TSUMURA KOHEI
IPC: B29L31/00
Filed: 1987-01-12
Abstract: PURPOSE:To obtain a coil spring having a fiber orientation angle as designed, by cutting spirally a fiber reinforced plastic (FRP) pipe and preparing thereby a coil spring. CONSTITUTION:A coil spring is prepared by cutting spirally a FRP pipe prepared by winding a continuous filament in a defined orientation angle. As the reinforcing fiber, carbon fibers and glass fibers and so on can be used and the carbon fibers is the most suitable one for weight saving as it has high elastic modulus. Heat resistance is required to the resin used as the coil spring is used in various places, so that heat-setting resins such as epoxy resins, polyester resins and so on can be preferable. Among the molding methods of FRP, the filament winding process is suitable for molding the coil spring which requires high strength and elastic modulus as it can provide the orientation angle with good accuracy. It is most preferable that the fiber orientation angle of the FRP pipe should be + or -30-+ or -60 deg. against the axial direction of the coil spring after cutting.

Filed: 1986-01-13
Abstract: PURPOSE:To obtain a thermal printer capable of estimating a printing state without performing printing, by providing a temp. detection mechanism, which detects temp. necessary for printing by a thermal element, to the main body of a thermal printer. CONSTITUTION:In a thermal impact printer, a printing head 4 moves to the position of a temp. detection mechanism 1 immediately after a power source is closed or before printing operation is started and is allowed to generate heat by the supply of a current to a thermal element 6 and the temp. detection mechanism 1 changes an electrical signal corresponding to the temp. of said head 4. The temp. detection mechanism 1 detects the change in temp. from the outside as the change in the electrical signal but, because a signal level is weak, said signal level is amplified by an amplifying part 7 and the output thereof is converted to a digital signal by an A/D converting part 8 to be inputted to CPU9. CPU9 processes the input data to output the result thereof as alarm display or to perform printing control of two-pass printing or the control of the current made to flow to the thermal element 1. Therefore, trouble can be preliminarily discovered before printing operation.
