Title: Electrophotographic sensitive body
Inventor: FUJIMURA NAOTO
IPC: G03G5/14
Filed: 1984-04-14
Abstract: PURPOSE:To prevent fluctuation of electric resistivity due to change in humidity by incorporating polystyrene and an electron donor in an undercoat layer. CONSTITUTION:An electron donor, such as poly-N-vinyl-carbazole, poly-1-vinylpyrene, ethyl carbazole, fluorene, or pyrazoline, is incorporated in the underlayer formed between a substrate and a photosensitive layer and made of a solvent- soluble hardenable type polystyrene type resin, such as polystyrene, styrene- sulfonic resin, or styrene-acrylic resin, having an electric resistivity of <=10<15> OMEGA.cm. The electron donor is added, preferably, in an amt. of 1-50,000ppm. The figures illustrate the cases in which positive electrostatic charge is injected in the dark, and it is injected conventionally as shown in (1), but the underlayer hinders the injection, as shown in the case (2) of this invention.

For example, a first resistor 12 and a second resistor 13 of different kinds are buried in a discoid ceramic substrate 11 and the resistance R1 of the first resistor 12 at a room temperature is set so that it can become the optimum value in a temperature range from the room temperature to 300 deg.C. The resistance R2 of the second resistor 13 at the room temperature, on the other hand, is set lower than the R1 so that it can become optimum when the resistor 13 is heated to >=300 deg.C.

Abstract: PROBLEM TO BE SOLVED: To eliminate such a possibility that an incorrect information transmis sion takes place even when a display surface is irradiated with disturbance light by arranging display elements on a printed circuit board and arranging dummy display elements around the display elements. SOLUTION: In the display unit, which constitutes display patterns, such as characters, graphics and patterns, by arranging the display elements 2 on the printed circuit board 1 and drives the display elements 2 to emit light so as to display the display patterns by light emission, the dummy display elements 3 are arranged around the display elements 2.  Since the dummy display elements 3 are arranged around the display elements 2 according to this constitution, if the display elements 2 are driven to emit light, the transmission of the information contents is made possible, and on the other hand, even if a pseudo lighting phenomenon is caused by reflection of light at the dummy display elements 3 when the disturbance light (for example, the afternoon sunlight, etc.), shines in the display parts where the display elements 2 are held put out, the pseudo lighting patterns are merely recognized and the recognition of the character 'VACANT' in relief is avoided and a wrong information transmission may be prevented.

Title: Fixed quantity supplying method in tea leaves conveyor
Inventor: TERADA JIYUNICHI
IPC: B65G47/19
Filed: 1978-06-20
Abstract: PURPOSE: To stably supply a fixed quantity of tea leaves to a steamer, by detecting the presence or absence of tea leaves in a hopper and controlling the speed of a downstream conveyor.  
     CONSTITUTION: A measuring unit 8 receives the tea leaves from an upstream conveyor 14 and meansures a prescrived quantity of the tea leaves. The prescribed quantity of the tea leaves are then thrown into a hopper 2 at a time interval set by a timer 10. The moving speed of the downstream conveyor is set on the basis of such a level that the prescribed quantity of the tea leaves are thrown into the steamer at the time interval set by the timer 10. As soon as the measuring unit 8 starts throwing the tea leaves into the hopper 2, the presence or absence of the tea leaves in the hopper 2 is confirmed by a photoelectric tube 3. If even a small quantity of tea leaves remain in the hopper 2, the moving speed of the downstream conveyor is set high. If no tea leaves remain in the hopper 2, the speed of the downstream conveyor is set low. The conveyance speed of the tea leaves are thus controlled.

Title: Multiplex transmission system
Inventor: YAMADA ATSUSHI
IPC: H04J3/00
Filed: 1984-04-13
Abstract: PURPOSE:To attain the back-up of a transmission signal and to improve the reliability of a multiplex transmission system, by preparing plural transmission lines for transmission of signals to terminal devices from a master device to detect faults such as a short circuit or an open state of the transmission line, etc. and using other nondefective transmission lines to transmits signals to terminal devices. CONSTITUTION:A double system of transmission lines is prepared, and these two systems are different electrically from each other and use the information for the same purpose. A main function part 5 reads the address data on the transmission signals to judge whether or not the part 5 itself is called or to control the load by the control data. If a transmission line 1a disconnected or short-circuited, the other transmission line 1b is used instead of the line 1a. While the line 1a substitutes the line 1b if the line 1b is faulty. In the case of a disconnection, a suviving repeater terminal device 2 satisfies 1anot equal to 1b. This means clearly that the detection is possible. Then either one of both transmission line systems has breakdown in the case of a short circuit. This also means clearly that the detection is possible. In the case of a dual loop, a back-up action is possible despite the simultaneous disconnections of both lines 1a and 1b.
