Title: Two-color image forming device
Inventor: EGAMI HIDEMI
IPC: G03G13/01
Filed: 1984-10-27
Abstract: PURPOSE:To speed up a process by forming positive and negative electric charge patterns on the surface of a solid dielectric material then developing the same by toners of different polarities thereby forming the toner images of two colors. CONSTITUTION:The electric charge pattern corresponding to the color signal of the 1st color is applied by the 1st digital electrostatic charger 4. The latent image of the charge pattern corresponding to the color signal off the 1st color is developed by a red toner of a negative polarity in a developing device 5 for the 1st color. The charge pattern corresponding to the color signal of the 2nd color (for example, black Bl) is applied by the 2nd digital electrostatic charger 6 and the surface of the dielectric drum is electrostatically charged. The latent image of the charge pattern corresponding to the color signal of the 2nd color is developed by the black toner of the positive polarity in a developing device 7 for the 2nd color. The toner images are charged to the negative polarity by an electrostatic charger 8 before transfer as the drum 1 rotates. The charge of the polarity reversed from the polarity of the toner is thereafter applied from the rear of the transfer material P by an electrostatic charger 9 for transfer and the toner images on the drum are transferred to the material P. The material P is conveyed in succession and is fixed by a fixing device 10.

Title: Image forming device
Inventor: KURAMOCHI YOSHIMI
IPC: G03G21/00
Filed: 1994-09-21
Abstract: PURPOSE: To deal with such a phenomenon that the load torque of a developing unit is increased, by using a motor having the property of decreasing torque in accordance with the increase of a rotational speed as the motor of a photoreceptor drum and making the rotational speed just after the power supply is started, lower than that at the time of forming an image. CONSTITUTION: Main motor 24 is a DC motor having the property of decreasing the torque in accordance with the increase of the rotational speed and a one chip microcomputer 15 transmits start/stop signals to a main driver 23. It dirvers/stops the main motor 24 based on the signals. A clock made by an oscillation circuit 100 is frequency-divided to make a reference clock. The main driver 23 determines the number of rotations of the motor based on the reference clock. The one chip microcomputer 15 drives the main motor 24 to rotate the photoreceptor drum for its initialization. At this time, the number of rotations is reduced and the torque is made large.

Title: Compensator of variation of time axis
Inventor: IMAMURA OSAMU
IPC: G11B5/027
Filed: 1982-12-27
Abstract: PURPOSE:To reduce satisfactorily the DC level variation of a video signal delivered from a delay element by connecting an adder to the output side of a variable delay element to detect the DC level variation and supplying the detected level variation to one side of the adder so as to reduce the DC level variation of the adder output. CONSTITUTION:A CCD1 serves as a variable delay element which controls the compensation of the time axis variation of an input signal (a) in response to the change of the clock frequency. The output of a voltage control oscillator VCO2 is impressed to the CCD1 in the form of a clock signal. The frequency of the clock signal is controlled by a control signal (b) for compensation of time axis variation. The DC level of the signal (a) varies as the clock frequency is changed. Therefore the reproduced video signal of the output signal of the CCD1 receives the variation of the DC level and is supplied to an input terminal of an adder 5. A signal which eliminates the DC level variation of the reproduced video signal is supplied to the other input terminal of the adder 5. Thus a negative feedback loop is formed to detect the DC level variation of the reproduced video signal including the remaining DC level variation, i.e. the output signal of the adder 5 through a DC level detector 3. Then the output signal is supplied to the other input terminal of the adder 5 through a phase compensator 4. Thus the DC level variation of the reproduced video signal is suppressed.

Abstract: PROBLEM TO BE SOLVED: To reduce the heat capacity of a plate material constituting an exhaust manifold and early activate a catalyst just after starting by connecting a plurality of plate materials to form the exhaust manifold, and setting the thickness of the plate material, of the both, which is located on the front side of the air flow within an engine room and satisfactorily cooled relatively small. SOLUTION: This exhaust manifold is formed by connecting at least two plates. For example, it is formed of a branch pipe 26 consisting of a cylindrical plate material, and an upper case part 28 and lower case part 30 formed of a bent plate material. The thickness t1 of the upper case part 28 located on the front side of the airflow in an engine room 4 is set relatively smaller than the thickness t2 of the lower case part 30 located on the rear side. According to this, the upper case part 28 is satisfactorily cooled with the airflow to increase the allowable stress, so that it can be thinned without deteriorating the strength. Accordingly, the heat capacity of the upper case part 28 can be reduced to prevent the reduction in exhaust air temperature, and the catalyst can be early activated just after starting.

Filed: 1989-09-01
Abstract: PURPOSE:To reduce the influence to the fluctuation of an input/output characteristic of a circuit when a process parameter fluctuates by constituting a load transistor and a driving transistor of the same enhancement type transistors. CONSTITUTION:A first field effect transistor T1 that functions as a load resistor is constituted of the enhancement type field effect transistor which is the same as a second field effect transistor T2 that functions as the driving transistor.

Abstract: PURPOSE:To prevent deterioration in the electric characteristic in the operation by giving a slit to both ends of an insulator of a coaxial cable for a cooling type terminator and spreading the slit. CONSTITUTION:The slit is applied to both ends A of the insulator 2e of the coaxial cable 2 of a waveguide-coaxial converter and the tip is spread.
