Title: Method and device for development of copying machine
Inventor: TODA AKITOSHI
IPC: G03G15/08
Filed: 1983-11-22
Abstract: PURPOSE:To obtain a sharp copy image with a little fogging by scattering a single-component developer by mechanical oscillations and performing contactless development. CONSTITUTION:When toner is supplied and a copying machine is put in operation, the toner 9 supplied onto an electrode 6 which serves as a toner carrier is scattered toward an electrostatic latent image holding member 1 by oscillations of a piezoelectric oscillator 4 applied with a high frequency voltage and stuck selectively on only image parts of the electrostatic latent image holding member 1 by the electrostatic attractive force of the image parts. Therefore, the advantages of a powder cloud system such as good gradations and the use of nonmagnetic toner are obtained. In general, when magnetic toner is used for a developer for color copying, a dark color is reproduced owing to a magnetic component, but the phenomenon is sliminated by using the nonmagnetic toner, so the use of the nonmagnetic toner is advantageous to the color copying.

Title: Controller for clothing drier
Inventor: KAWASAKI TAKERU
IPC: D06F58/28
Filed: 1990-08-20
Abstract: PURPOSE:To stabilize a heater load current at a level less than a constant value and to improve drying efficiency by controlling a fan rotating speed adjusting means for the adjustment of the rotational speed of a rotary fan corresponding to a load current that flows in a heater. CONSTITUTION:When a heater load current detecting means 8 detects the fact that the load current of the heater 7 exceeds a prescribed critical value, the rotation of the rotary fan 3 is decreased to a certain value by the fan rotating speed adjusting means 11. When the load current of the heater 7 goes down less than the prescribed critical value, the rotational speed of the rotary fan 3 is increased again, and such operation is repeated while driving is continued. Thereby, air quantity to be sent to the heater 7 can be decreased by decreasing the rotational speed of the rotary fan 3, and the ambient temperature of the heater 7 rises, and the heater load current is reduced. Also, the air quantity to be sent to the heater 7 is increased by increasing the rotational speed of the rotary fan 3, and the ambient temperature of the heater 7 goes down, and the heater load current is increased. Therefore, it is possible to stably control the heater load current less than the constant value by adjusting the rotational speed of the rotary fan 3.

Title: Pressure controlling method for casting machine
Inventor: OZEKI TOSHIYUKI
IPC: B22D18/08
Filed: 1985-10-02
Abstract: PURPOSE:To produce castings having the same quality by counting the number of pouring and correcting the pressure during the pressurization in accordance with the count value in the stage of exerting the pressure to the molten metal in a holding furnace and pouring the molten metal into a casting mold so that the pressure on the molten metal in the pouring port is made always the same in spite of a fall of the molten metal level in the holding furnace. CONSTITUTION:A pressurization curve generator 4 generates the signal at which the pressure in the holding furnace 9 is made optimum for initial casting. Said signal is determined as the set value of a pressure controller 6. The pressure controller 6 receives the signal for the inside pressure of the holding furnace measured by a pressure gage 7 as the measured value and makes the feedback control by the deviation of said value from the set value, then the controller controls the opening degree of a valve 8 in such a manner that the holding furnace is pressurized to conform to the pressurization curve. A counter 2 which counts the number of casting increases the count by each one time by a start command 1. The set value of the controller 6 is corrected by as much as the number of casting, i.e., the pressure component proportional to the count value of the counter 2 with respect to the set value from the generator 4.
