Title: Electric power amplifying circuit
Inventor: OOTAO KAZUMASA
IPC: H03F3/20
Filed: 1979-06-18
Abstract: PURPOSE:To prevent switching distortion by keeping all the transistors at ON state regardless of the polarity of input signal, by connecting the series circuit of a resistor and a capacitor between the common junctions with two sets of resistor and diode. CONSTITUTION:The series circuit of a resistor 13 and a capacitor 12 is connected between the common points of the resistor 3 and the diode 4, and the resistor 9 and the diode 10. Further, when the input signal of positive half cycle is input, the emitter current of transistors TR1, 2 is increased and power is fed to the load 6, but TR7 keeps ON-state. This is the same when the input signal of negative half cycle is fed. In this case, since forward voltage should be fed to the diodes 4, 10 at all times, the resistance value of the resistors 3, 9 is selected so that forward voltage is always fed to the diodes 4 and 10. Accordingly, TR1, 2, 7, 8 are always at ON state, resulting in preventing switching distortion.

IPC: G03G15/08
Filed: 1995-03-31
Abstract: PURPOSE: To generate an image of good quality always even before and after the refilling of a new developer to a developing device by changing the potential of a developer bearer and the potential of the developer attaching part of an electrostatic latent image while a specific relationship between them is maintained in the case where the residual quantity of the developer is going out. CONSTITUTION: A photoreceptor drum 1 is an OPC substance and charged negative, and an electrostatic latent is formed by a latent image forming means, and the surface of a developing roller 2 as a developer bearer which carries a toner 7 is moved in the direction of an arrow so that the obtained latent image is developed by the inverted development. When the toner in a toner hopper 6 lessens, the relation of the potential of a developing roller 2 to the potential of the developer attaching part of the latent image is changed so that the toner 7 can easily move from the roller 2 to the developer attaching part of the latent image.  Even in the case where the toner quantity in the hopper 6 is going out to cause poor toner existence on the roller 2, the electrostatical force of moving the toner 7 on the roller 2 toward the photoreceptor drum 1 will increase, and a stable development density is obtained.

Title: Method and device for die casting
Inventor: YAMAUCHI TOKUJI
IPC: B22D17/00
Filed: 1980-06-06
Abstract: PURPOSE: To prevent the formation of cavities, and the formation of burrs at the parting plane of molds and obtain die cast products of high quality by injecting the molten metal filled in an injection sleeve removed of air into the die space formed by a stationary die and a movable die.  
     CONSTITUTION: An injection sleeve 14 is closed by a core 45, and molten metal is filled in the sleeve 14 which has been expelled of air during die opening. Thence, the molten metal in the sleeve 14 is injected under high pressure into the die space 30 formed by bringing a stationary die 18 and a movable die 26 into close contact with each other, thereby producing a die cast product. This eliminates the inclusion of the air in the sleeve 14 together with the molten metal into the die space 30 at the injecting of the molten metal, makes the formation of the layers (cavities) of air in the die cast product difficult, and considerably improves the quality of the die cast product. Since the molten metal is injected after it is filled in the sleeve 14, the pressure and moving speed of a plunger 13 at the injecting are lowered, the formation of furrs is suppressed and the life of the dies is prolonged.

Title: Constant speed travel device
Inventor: KAWABATA WATARU
IPC: F02D41/14
Filed: 1990-03-27
Abstract: PURPOSE:To stabilize a car speed after acceleration ending by controlling a throttle return value at time of the acceleration ending so as to become a different value with on-off operation of OD, in a constant speed travel device using a vacuum driving type actuator. CONSTITUTION:A constant speed travel controller 1 stores a car speed at that time in a desired car speed memory when a set switch is pushed, thereby starting its constant speed travel control. Then, it controls a control valve CV of an actuator 2 so as to make a difference between desired car speed and travel car speed into zero. In addition, when a resume switch is pushed, the desired car speed in the memory is renewed upward at a constant ratio as long as this on-time. In a short time, if the resume switch comes off, off-control over a relief valve RV is performed. At this time, an OD on-off signal at the side of a shift controller 4 is judged, and if it is OD-ON, long off-time is used. If so, even if throttle opening TA is largely opened by the OD-ON, thereby coming to an end of acceleration, a return value of a throttle 3 grows larger than ever before so that a car speed overshoot can be held down to lowess.
