Patent JP-H0664468-A (JP)
Title: Rotating action damper
Inventor: SUZUKI KENICHI
IPC: B60R7/06
Filed: 1992-08-24
Abstract: PURPOSE:To simplify a structure, and thereby lower its cost by repeating both an action that a spring clutch is instantly rotated against a spring acting as a damper while being integrated with a shaft, and an action that the spring clutch is instantly rotated in the direction reverse to that of the shaft, and thereby attenuating the torque of the shaft. CONSTITUTION:When a shaft 2 is rotated to the direction X as indicated by an arrow head, both two kinds of actions are instantly repeated so that the torque of the shaft 2 is attenuated by the elastic contraction resistance of a compression spring 10 as follow: one action is that a spring clutch 3 is rotated in such a way that its diameter is reduced due to friction with the shaft 2 while the compression spring 10 is being elastically contracted integrally with the shaft 2, and the other action is that the spring clutch is rotated so as to be returned by the elastic force of the compression spring 10 to the direction of Y as indicated by an arrow head in such a way that its diameter is enlarged while being slid against the shaft 2. Since damping function is kept active at all times while the shaft is kept in its rotation, the range of damping function will never be limited as an oil damper is limited, it is thereby possible to exhibit damping function over a long stroke.

Title: Thermal transfer recorder and facsimile device using the recorder
Inventor: WADA SATOSHI
IPC: B41J17/04
Filed: 1988-10-04
Abstract: PURPOSE:To make it possible to control the ratio of feed velocity of an ink sheet to that of a recording medium in accordance with image data by determining the velocity of the ink sheet relative to the recording medium according to the characteristics of the image data, and controlling an ink sheet-feeding means based on the relative velocity. CONSTITUTION:When a recording paper-feeding motor 1 is excited by one step, a recording paper 11 is fed in a direction (a) by a length L. On the other hand, when an ink sheet-feeding motor is excited by one step, an ink sheet 14 is fed by L/n. When image data is received in a fine mode, the value of n is set at to be a2, whereas when the data is received in a standard mode, the value of n is set to be a3. Based on the determined value of n, a table for determining the number of exciting steps for the ink sheet-feeding motor, an exciting phase for the motor and the like is formed, thereby obtaining a rotating speed of the ink sheet-feeding motor according to the value of n. Because the relative velocity ratio, n, of the recording medium to the ink sheet can be controlled, wrinkling of the ink sheet or the like can be prevented, and recording quality of an original image or received image data can be enhanced.

Abstract: PURPOSE:To manufacture a plastic mirror high in light reflection factor at a low cost by forming a thin silver skin layer by means of silver plating after the surface of transparent plastic resin in a form of a plate or a film is activated so as to be coated with a surfactant. CONSTITUTION:A transparent polycarbonate resin in a plate form is immersed in a tin chloride aqueous solution for one minute, and next, it is immersed in a palladium chloride aqueous solution for one minute so as to be activated at its surface, so that it thereby adsorbs palladium having a catalytic function. Following which, a surfactant solution is thinly applied over the surface of the transparent resin plate, so that hydrophilic property is imparted thereto. A silver plating solution immediately after those such as an ammoniacal silver nitrate aqueous solution, a sodium hydroxide aqueous solution and a glucose aqueous solution are mixed by the ratio of 4:1:1 at ambient temperature equal to or more than 15 deg.C, is applied over the surface of the transparent resin plate as to be left as is. By this constitution, after a thin silver layer has been formed, a copper protective film is formed thereon by a copper sulphate aqueous solution and a reducing agent solution, and back coating is then applied thereto so as to be sealed.

Filed: 1986-10-20
Abstract: PURPOSE:To reduce the number of parts and to improve the reliability of an action by forming a cam groove in loading arms, movably fitting a drive pin that is displaced by a drive means and driving the loading arm due to the relative displacement of the drive pin. CONSTITUTION:At the time of loading, a reel structure gear 32 turns clockwise due to the turn of a motor 29 in a prescribed direction. In response to the turn, the drive pin 34 sequentially advances in groove parts 14a, 14b and 14c and relatively shifts in the cam groove 14. At that time, the drive pin 34 energizes the left edge of the cam groove 14, which energizing renders the loading arm 5 to start turning counterclockwise. Together with the turn the loading arm 6 starts turning clockwise with a supporting shaft 16 as a center. Pull-out poles 4 and 5 pull out a magnetic tape 15 toward a prescribed tape path in front of a standard tape cassette. In such a way the loading arm 6 can surely load, and simultaneously a structure in an adapter 1 can be simplified.
