Title: Plate end working device
Inventor: SHIMIZU KAZUYA
IPC: B23C3/12
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a plate end working device in which the working accuracy is improved by securing an energizing force in the plate end face direction at the running front end side, and stabilizing the running of the device. SOLUTION: To a running roller 3 at the running front side abutting to the upper surface of a work P, a taper 9 in order to generate a torque to the inner side of the work P is formed. A driven roller at the running rear side is formed in a drum shape, and the driven roller 4 and the upper surface of the work P are abutted at a small area. As a result, a torque to the inner side of the work P is generated while the running roller 3 is being rotated and advanced. At the same time, since the driven roller 4 is abutted with the work p at a small area, the contact resistance to the work P is reduced. Consequently, the energizing force in the plate end face W direction is secured easily. Thus, the running against the reaction by the working is stabilized, and the working accuracy is improved.

IPC: G03B13/36
Filed: 1985-04-23
Abstract: PURPOSE:To return a photographic lens to an initial position securely with small motor power by supplying a motor with a signal which moves forth the lens temporarily when the photographic lens is returned. CONSTITUTION:The guide pin 5 of a photographic lens frame is supported while restrained by both a straight advance groove 27 in an optical-axis direction which is provided to a lens barrel fixation part and the cam groove 42 of a lens driving member 40 and the pin is moved in the direction of the optical axis by the rotation of a driving member 40. In this case, the slanting surface of the cam groove 42 is pressed strongly against the pin 51, so a large rotational force is required to return the lens to its initial position. For the purpose, the signal which moves the lens 50 in the forward direction temporarily is supplied to the lens 50 when the lens is returned. Consequently, the frictional resistance generated between the cam groove 42 and pin 51 is reduced and the lens 50 is returned to its initial position with the small power of a motor.

IPC: H04N3/20
Filed: 1983-05-18
Abstract: PURPOSE:To simplify constitution and provide versatility by cutting off a cathode-ray tube for a short time by the 1st grid and for a long time by a cathode circuit. CONSTITUTION:When a power switch is turned off, it takes several milliseconds to cut off a video output Tr2 because it operates with a class ''A'' bias, but the cathode 9 of the cathode-ray tube 8 is held at the charged voltage of a capacitor 7 for a long time after the Tr2 is cut off by using a large-capacity capacitor 7 for rectifying a video output voltage. The voltage of the 1st grid 10 is only held negative for a short time to erase a luminescent spot. Namely, a high voltage applied to the 2nd grid 11 is cut off by a capacitor 18 to hold the potential of the 1st grid 10 negative instantaneously, erasing the luminescent spot. This method is applicable to a system which varies the luminescence on a monochromatic display screen by varying the 1st grid.

Filed: 1990-04-02
Abstract: PURPOSE:To omit the undesired requests for change of a manipulated variable by obtaining the final answer value of a system set on the assumption that the manipulated variable obtained right after its change is maintained as it is and deciding the propriety of change of the manipulated variable already carried out based on the final answer value and the controlled variable actually measured at the present point. CONSTITUTION:The dynamic characteristic of a system is previously obtained, and a manipulated variable is carried out when a due changing request is received from a computer. Then the final answer value of the system is obtained based on the system dynamic characteristic and on the assumption that the manipulated variable obtained right after its change is maintained as it is. Then the influence of the change of the manipulated variable given to the output is quantitatively evaluated based on the final answer value and the controlled variable actually measured at the present time point. Thus it is judged whether the requests for the changes of the manipulated variable of the computer which are continuously received even after a change of the manipulated variable is carried out are necessary or not. Then it is possible to omit the undesired commands for change of the manipulated variable and to prevent the misoperation.
