Title: Method for transmitting driving power to ram in crank press
Inventor: YOSHIDA SHIGENOBU
IPC: B30B1/26
Filed: 1994-06-03
Abstract: PURPOSE:To attain speeding-up in the reciprocal linear movement of a ram and improvement in productivity by transmitting the driving power of an actuator to the ram through a crank shaft and oscillating the crank shaft of a crank press, which imparts a reciprocal linear movement to the ram, left and right at only a prescribed angle centering the moving direction of the ram. CONSTITUTION:A crank shaft 18 is oscillated left and right at a prescribed angle theta centering the moving direction (center line A) of a ram 20. This oscillating operation of the crank shaft 18 is performed by measuring the angular displacement of the crank shaft 18 by a detector and driving a motor forward and backward in accordance with the measurement. That is to say, a signal is given from a computer to the motor at the point of time when a set oscillating angle coincides with the detected value of the detector. Incidentally, it is effectively controlled if the detection is possible by the detector on the information immediately before the ram 20 reaches a bottom dead point and if the motor speed is reduced at such time.

Title: Dimming method of copying machine
Inventor: SHIBUSAWA MITSUO
IPC: G03G15/04
Filed: 1978-10-04
Abstract: PURPOSE:To achieve smaller-size of copying machine, lower cost, longer maintenance intervals, better operating characteristic, etc. by so constituting the copying machine that adjustment of the quantity of exposure light may be performed electrically from its control panel. CONSTITUTION:Variable resistances VR1 and VR2 are used in series to an automatic voltage regulator AVR 1 and are disposed on the control panel of the copying machine. If the maximum resistance value of the variable resistance VR1 is selected larger than the maximum resistance value of VR2 and VR2 is set maximum at the initial period of using the copying machine, then the distributing angle that may be changed with VR1 becomes, e.g., from t2 up to t4. When the copying machine is used for a long period of time, the insufficiency of the quantity of light results from the decreased quantity of light of the halogen lamp HL and stained optical system. If at this time VR2 is gradually approached to zero, the quantity of light may be gradually increased by shifting the distributing angle to the larger one such as from t1 up to t3 and therefore the maintenance intervals may be made longer and the smaller size and lower cost of the copying machine may be made possible.
