Title: Composite photoreceptor for electrophotography
Inventor: ODA TOORU
IPC: G03G5/04
Filed: 1979-04-12
Abstract: PURPOSE: To obtain a 2-color copy high quality of one imagewise exposure step, by forming a photoreceptor having 2 photoconductive layers different in sensitivity to a chromatic color, and providing a resin dispersion layer containing TiO 2  and a red- sensitizer as the second photoconductive layer.  
     CONSTITUTION: First photoconductive layer 12 of amorphous Se or the like is formed on electroconductive substrate 11, and layer 2 is made conductive by a chromatic color light, e.g., a nonred light transmitted through second photoconductive layer 14, and on layer 12 layer 14 consisting of TiO 2  and a red-sensitizer (bromophenolblue, or so) becoming sensitive to red light is formed to prepare photoreceptor 1. Photoreceptor 1 undergoes successively first corona charging as being irradiated by light through a red filter to render the surface potential negative, second charging in a somewhat smaller amount to render the surface potential positive, exposure to the light image of original 2 to give surface potentials corresponding to black BL, white W, and red R of original 2 different in polarity, and development with black toner Tb and red toner Ta different from each other in polarity, thus permitting a 2-color sharp copy to be obtained.

Title: Optical lens
Inventor: KAMIWAKI OSAMU
IPC: G02B3/12
Filed: 1980-04-03
Abstract: PURPOSE:To change focal length by the lens alone by forming the lens with light transmittable fluid material and light transmittable solid holding said fluid material. CONSTITUTION:Transparent fluid material 2 such as alcohol is filled in a lens outside shape part 1 which is formed of transparent plastics and has specified curvature, whereby a lens is formed. If the pressure P is applied to the lens inside through a deforming part 6 by operating a pressure varying device 6, the internal pressure (p) of the lens changes and the curvature of the part 1 changes. As a result, the  focal length of the lens is changed. Even without the pressure varying device, the  focal length is adjusted by changing the sealing pressure of the fluid material 2 to  be filled in the inside at the production of the lens.

Title: Signal transmission circuit by pulse transformer
Inventor: TSUDA MASANORI
IPC: H03K17/60
Filed: 1985-03-05
Abstract: PURPOSE:To obtain a practical circuit without signal propagation delay by constituting a short-circuit at the primary when a switch function is moved to the primary side to switch an output signal from high to low level so as to short-circuit an induced magnetic flux of a pulse transformer thereby rejecting it. CONSTITUTION:In turning alternately on, off switches S21, S22 with a switch S24 turned off and a switch S23 turned on at first, a high signal H is fed to a load. In switching a signal into the low signal L, when the switch S22 is turned off and the switch S21 is turned on, a high signal H with the same voltage E1 as that of power supply is fed to the load circuit. In turning off the switch S21, turning off the switch S23 and turning on the switch S24 to select the low signal L in this state, since an exciting current is going to flow, the current flows in the path of PT1(A)-S24-D22-PT1(A) and the residual magnetic flux is consumed through the path. Thus, the voltage fed to the load circuit is the low signal L at switching and no signal transmission delay is caused.

IPC: G03G21/10
Filed: 1992-03-02
Abstract: PURPOSE:To realize an electrostatic charging device capable of stably and uniformly electrostatically charging the surface of a photosensitive body which holds toner or paper powder and an image forming device in which the electrostatic charging device is applied. CONSTITUTION:The photosensitive body 2 holding the residual toner 22 or the paper powder 24 on its surface rotates to a contact part with an electrostatic charging contact 4. The contact 4 rubs the residual toner 22 and the paper powder 24 on the surface of the photosensitive body 2 and electrostatically charges the surface of the photosensitive body 2 while it is moving. In spite of the existence of the residual toner 22 and the paper powder 24, the contact 4 directly comes in contact with the surface of the photosensitive body 2 and a stable electrostatic charging state is realized. Furthermore, surface adhesive force with the photosensitive body 2 is reduced by moving the residual toner 22 and the paper powder 24.

Abstract: PURPOSE:To run a magnetic tape stably by varying the coefficient of friction of the surface of a tape guide which guides the run of the magnetic tape according to the tape width direction, and providing a groove in the guide surface or tapering a guide roller. CONSTITUTION:An upper tape guide surface 11 has a greater coefficient of friction than a tape guide surface 13.

For this purpose, pins are provided to hold the running  height of the tap constant. During the manufacture of the guide pins 14, the  guide surface 12 is made wider than the tape, facilitating the process. When the  guide surface 12 is lower, the coefficient of friction of the guide surface is increased toward the upper part. In another way, a groove 17 whose area increases toward the upper part or a tapered roller 18 whose diameter decreases  toward the lower part is provided to obtain the same effect.

IPC: H01G9/055
Filed: 1989-02-23
Abstract: PURPOSE:To increase the junction strength of the connection part between an electrode etching foil and a lead-out wire, to make it possible to merchandize a high capacitance etching foil by reducing contact resistance, and also to improve high frequency characteristics by a method wherein a lead-out wire is connected to the non-etching core metal layer which is exposed by removing the principal part of an etching layer after a dielectric oxide film has been formed. CONSTITUTION:An etching treatment is conducted on aluminum foil or aluminum alloy foil, and after an etching layer 1 has been formed on its outer surface side and a non-etching core metal layer 2 has been formed inside said foil, a dielectric oxide film is formed on the surface of the above-mentioned layers. Then, after the non-etching core metal layer has been exposed by removing the principal part of the etching layer 1, a lead-out wire is connected to the exposed non-etching core metal layer 2. For example, a stainless steel roughened roller 3, provided with BN coating, is brought into contact with the above-mentioned foil while the roller 3 is being rotated, and the non-etching core metal layer 2 is exposed by partially removing the etching layer 1. Subsequently, the tab 4 of the lead-out wire is junctioned to the exposed non-etching core metal layer 2 using a needle-aperture caulking method.

Title: Rotor fixing device
Inventor: TOKUNAGA KEISOKU
IPC: F16D1/06
Filed: 1990-02-26
Abstract: PURPOSE:To increase transmission power, and to prevent eccentricity and the loosening of a screw by making a press screw portion of a boss hollow, by providing a notch on the boundary of the boss and a rotor main body, and by providing a press pin on the reverse side of the press screw. CONSTITUTION:When a press screw is screwed in, a boss hollow part 1 receives a reaction outward by which a shaft is pushed. At the time, since the displacement of the boss part is easy due to the flexibility of a notch 2, the displacement is directed in the side of the press screw. Since a pin 3 placed on the lower part is moved upward, and gives the same force to the shaft, the shaft is fixed by the press screw as well as the pin 3. Since the boss and a rotor main body are linked with each other through the remainder of the notch 2, rotational force is transmitted therethrough. Transmission power is increased thereby, and eccentricity due to the effect of the power of the press screw does not occur. Also, the screw is not loosened due to the elastic effect generated by the notch 2. Advantages of a conventional compactness and the same handling operation can thus be obtained.
