Filed: 1981-08-21
Abstract: PURPOSE:To expedite the pattern recognition of a perforating position, by scanning a detector wherein photoelectric elements are arranged in the X and Y directions with respect to a dril hole detecting film. CONSTITUTION:The film having the dimensions X and Y, wherein detecting positions including a reference point are shown, is placed on a base table 3. The photoelectric elements, which detect the optical concentration of the opposing position on the film, are arranged in the Y direction at a specified interval in the detector 6, which has the detecting region of a specified dimension Y. Said detector 6 is relatively moved in the X/Y directions on the base table 3. The optical concentration of the film is detected every time the detector 6 is moved in the X direction at a specified distance. The pattern of the detected positions is recognized and the amount of the movement in the X direction at this time is memorized. When this value becomes zero, the detector 6 is moved in the Y direction by a specified amount, and the amount of the movement is memorized. By the repetition of this scanning, the distances in the X and Y directions to the detected position are detected based on the sum of the amount of the movement in the X and Y directions and the offset amount to the corresponding photoelectric element of the detector 6 after the pattern recognition.

Title: Damper device
Inventor: HOUJIYOU AKUJI
IPC: F16F9/52
Filed: 1990-05-21
Abstract: PURPOSE:To enable a proper control of damper gear torque value by fixing one end of shape memory alloy controlled in its energization by means of a temperature seneor while connecting the other end to a movable damper device main body, and moving the main body to the damper gear through deformation of the main body to the low and high temperature side of the shape memory alloy. CONSTITUTION:A damper device is normally monitored in its circumferential ambient temperature. At the time of low temperature at which the viscousity of grease oil 15 increases, a shape memory alloy 16 shrinks to separate a damper device main body from a damper gear 14 thereby reducing the contact resistance area between the body 11 and the gear 14. As a result, a damper gear torque value decreases as the viscousity of gease oil 15 increases. When a circumferential ambient temperature moves from the low temperature to the normal temperature, the sensor senses it to supply current to the alloy 16 for heat emission, and thereby the shape is resumed to the shape at the time of high temperature to increase the contact resistance area so as to increase the damper gear torque value as the viscousity of gease oil 15 is decreased thereby when the temperature is returned to the normal temperature.
