Patent JP-H0919179-A (JP)
Title: Speed controller for dc motor
Inventor: INAMURA JUNSHIRO
IPC: H02P7/29
Filed: 1995-06-29
Abstract: PURPOSE: To facilitate dealing with the load variation of a motor, etc., and to make stable control possible by frequency/voltageconverting a reference clock, and applying voltage controlled constant in accordance with the reference clock by this output voltage to the motor. CONSTITUTION: A motor driving power source VS is controlled to a constant voltage VR not being influenced by the variation of a driving voltage VS by a voltage adjusting circuit 8 wherein a reference clock CK is controlled by the output of a second frequency/voltage converter 7, and is applied to a motor. When it is used as one for driving a light source of a copying machine, the output of the motor is small and required power is small too since the number of revolution is small, at the time of scaunning, but large power is required since the number of revolution is large and quick movement is required, at the time of returns. Accordingly, power transistors perform PWM control by switching, and PWM frequency is set high so as to make it possible to make the diode, capacitor, and inductance of a smoothing circuit extremely small.  As the result, it becomes possible to deal with the load variation of the motor, etc., easily and to perform stable control.

Title: Method for controlling pouring quantity of molten metal for casting
Inventor: IWADATE HISASHI
IPC: B22D37/00
Filed: 1987-06-30
Abstract: PURPOSE:To prevent development of deteriorated product and to improve the yield by detecting changing ladle gross weight and outputting a signal when the pouring weight and received molten metal weight reaches to the prescribed range based on the gross weight. CONSTITUTION:A wireless suspension weigher 1, receiver 2, buzzers 41, 42 and pilot lamp 5 are arranged to the ladle 3 for pouring respectively. When the receiving work of the molten metal starts, the gross weight changing at every moment is measured with the suspension weigher 1 and received with the receiver 2. Then, when the receiving molten metal weight is more than the receiving molten metal setting weight minus running dropped weight from the ladle and less than the setting weight, the buzzer 41 or 42 is alarmed and when the receiving molten metal weight reaches to the setting weight, the pilot lamp 5 is switched on. At the time of pouring the molten metal, also the same operation is executed. By this method, as the receiving molten metal weight and the pouring weight always coincide with the setting weights, respectively, the development of the defective product is prevented and the product yield is improved.
