IPC: G03G5/06
Filed: 1978-12-13
Abstract: PURPOSE: To improve dispersibility and dispersion stability of a fluid for forming a charge carrier generating layer in preparing a photoreceptor, by using a specified disazo pigment and a binder mixture of a specified mixing ratio of polyvinylbutyral- acrylic resin.  
     CONSTITUTION: The dispersion fluid to be used as a fluid for forming the charge carrier generating layer on a conductive substrate disperses in a polyvinylbutyral- acrylic resin mixture binder of 1:0.1W0.1:1 weight ratio, a disazo pigment represented by formula (X is an optionally substituted aromatic or heterocyclic ring; Ar 1  is same as X: Ar 2 , Ar 3  are each an optionally substituted aromatic ring; R 1 , R 3  are H, lower alkyl, carboxy, or its ester). This method permits a thin, smooth and uniform charge carrier generating layer free of coat fault, and a high sensitivity and low fatigue lamination type electrophotographic receptor to be obtained.

Title: Liquid crystal display device
Inventor: AOKI ISAMU
IPC: F21V8/00
Filed: 1989-06-19
Abstract: PURPOSE:To obtain a back light having a uniform luminance even when the back light type liquid crystal display device is used over a long period of time in an atmosphere of high humidity by forming the small projections to prevent tight adhesion on the opposite surfaces of a light transmission body and a reflecting plate of the above-mentioned display device. CONSTITUTION:The light radiated from a linear source 1 enters the light trans mission body 2 and repeats reflections and diffusions between this body and the reflecting plate 3 of the bottom plate. The rear surface of the liquid crystal display element is irradiated with this light through a diffusion plate 4. The small projections 5 of a prescribed height are provided at prescribed intervals on the reflecting plate 3. The contact of the reflecting plate 3 and the light transmission body 2 is obviated by providing the projections 5. Such an incident that the spacings are filled with water does not arise even if the water film of a very small thickness is generated on the surface of the reflecting plate 3 after the long-term use in the atmosphere of the high humidity. The back light having the uniform luminance is obtd. in this way.

Title: Signal transmitting circuit
Inventor: KISHI SHIGERU
IPC: H04L5/14
Filed: 1983-08-26
Abstract: PURPOSE:To use only one power source and to reduce parts in number by utilizing the fact that the voltage drop when a photoelectric element provided to a signal transmitting circuit conducts is smaller than the difference between the high-level threshold voltage at a signal reception terminal and a source voltage. CONSTITUTION:When a transmission terminal 2-c is at a high level, a transistor (TR) 3-c and a photocoupler 4-a turn on and a current flows to a resistor 6-e from a control circuit power source 1-b through a resistor 6-e to cause a voltage drop. For the purpose, the ratio of the resistors 6-b and 6-e is so selected that the voltage obtained by substrcting the voltage drop across the photocoupler 4-a from the voltage of the power source 1-b, i.e. the voltage drop across the resistor 6-b is within the high-level voltage range of the reception terminal 1-d of a control circuit 1-a. Consequently, a high-level signal is transmitted to a terminal 1-d only with the power source 1-b without requiring any dedicated power source.

Title: Power supply
Inventor: KAWABATA HARUO
IPC: H02M3/28
Filed: 1978-12-13
Abstract: PURPOSE: To prevent heating, deterioration and breakage of the transistor due to the voltage drop by differentially detecting the reduction of the input power voltage and then stopping the operation of the switching transistor.  
     CONSTITUTION: In normal operation, base potential of a transistor 21 is higher than that of a transistor 22, so all current from an output terminal 6 passing through a resistor 20 flows into the transistor 22 and a voltage drop across a resistor 25 becomes 0. when the voltage from an input power supply 1 is lowered gradually and becomes lower than the base potential of the transistor 22, the transistor 21 is turned to conduction. Therefore, all current that has passed through the transistor 22 up to that time starts to flow into the transistor 21 and produces the voltage drop across the resistor 25 so as to conduct a thyristor 31 of a protecting circuit 30. Through this conduction of the thyristor 31, a driving circuit 7 connected to the anode of the thyristor is short-circuited. This stops supply of the driving current to the base of a switching transistor 3 and thus the transistor 3 is turned off.

Title: El element
Inventor: YAMAMOTO YUJI
IPC: H05B33/22
Filed: 1990-06-13
Abstract: PURPOSE:To facilitate the manufacture of the EL element and suppress the expansion of a dielectric breakdown by interposing a buffer layer of silicon nitride between an EL illuminant layer and one or both of insulating layers. CONSTITUTION:By means of the plasma CVD method a buffer layer of silicon nitride, for example an SiNx layer, is formed at a lower temperature, for example 50 to 150 deg.C, than the usually adopted temperature condition of over 300 deg.C. Then, the temperature is raised to over 300 deg.C that is usually used, and subsequently to that a film of silicon nitride, or an SiNx film, is formed and a silicon oxide film is laminated so as to form a secondary insulating layer made of two layers. While an insulating layer and the secondary insulating layer are formed respectively at the order of a few 100nm in the film thickness, for example 300nm, less than 100nm, for example approximately 30 to 90nm, is enough for the film thickness of the buffer layer. However, a much thinner film than that can not utilize its function to suppress a dielectric breakdown, and a much thicker film can not be expected to extend the function.
