Title: Paper feeder for image forming device
Inventor: NIBU TORU
IPC: G03G15/00
Filed: 1989-10-06
Abstract: PURPOSE:To surely prevent jamming by providing No. 2 sheet return means which drivingly rotates No.1 and No.2 rotary feed members in the direction opposite to the form carrying direction based on a specified sheet return signal, and thereby forwarding sheets back to a sheet housing section, which remain in the vicinity of a duplicate fed prevention section while being prevented from being piled up. CONSTITUTION:When a sheet return signal is sent, a sheet returning member 43 is moved to the sheet returning direction. No.1 and No.2 rotary feed members 26 and 28 are then concurrently rotated, and thus sheets remaining in the vicin ity of a duplicate feed prevention section 27 are returned back to a sheet hous ing section. In this case, the sheet return signal is sent based on, for example, a detecting signal which is issued upon completion of image forming operations, a sheet supply signal to a sheet housing section, a detecting signal for the descending action of the sheet housing section when the sheet housing section of a form resting plate in the aforesaid section is lowered so as to be moved in order that the sheets are supplied, or the like.

Title: Liquid crystal display device
Inventor: FUJII TATSUHISA
IPC: G09G3/36
Filed: 1992-09-07
Abstract: PURPOSE:To provide the liquid crystal display device which makes a display of high quality. CONSTITUTION:When a simple matrix type liquid crystal display panel which has picture elements constituted at the intersections of scanning line electrodes and signal line electrodes is used and driven by a line sequential system and a voltage averaging method, a scanning line nonselection bias voltage is made small when the number of turn-ON signals supplied to a currently selected scanning line is smaller than the number of turn-ON signals supplied to the last scanning line or made large when large, and when the both are equal, the bias voltage is maintained as it is by voltage adjustment. A correction voltage VD1-VD2 matching a crosstalk component is generated to generate nonselection voltages V6 and V5 for scanning line electrodes, and consequently the crosstalk can be canceled, so that high display quality which is not affected by the crosstalk can be obtained.

Title: Picture processor
Inventor: KATAYAMA AKIHIRO
IPC: G06T1/00
Filed: 1990-09-30
Abstract: PURPOSE:To separate a line picture part with high accuracy by devising the processor such that a 1st extraction means extracts a line picture part in a prescribed color of an input picture data, a 2nd extraction means extracts a part of a color close to a prescribed color and the input picture data of the part extracted by the 2nd extraction means is revised. CONSTITUTION:Picture element picture data r, g, b in 8-bit are inputted to a color detector 71, in which a picture element of an extracted color is detected. In this case, a color character circumferential part is detected. In this case, a threshold level of color detection is revised to detect a color in a range wider than the color detection section thereby extracting a color part close to a color character and eliminating an input picture data of the part. In this case, an averaging value arithmetic circuit 73 calculates the mean value of the r, g, b data in an 8X8 picture element block, a replacement section 74 replaces the mean value as a picture element picture from which the color is eliminated and outputs the result as data r', g', b'. Thus, the line picture part of the picture is separated with high accuracy.

Title: Thermal flowmeter
Inventor: KENMOCHI SHOGO
IPC: G01F1/696
Filed: 1990-10-01
Abstract: PURPOSE:To improve the accuracy and to reduce costs by using a single heat sensitive resistance element and switching the heat sensitive resistance element to be used as a heat source of higher temperatures than a fluid or to be used for detection of the temperature of the fluid. CONSTITUTION:A switch 1A is connected to the side of a bridge circuit 1 while the air is allowed to pass through a flow passage. A current is supplied to the circuit 1 by an operational amplifier 2. When the circuit 1 is in the balanced state, a formula I is held. The temperature t of a heat sensitive resistance element RT as a heat source is detected as a constant of the apparatus. Moreover, the power P supplied to the element Rt, namely, the quantity H of heat radiated into the air is detected from the resistance value of the element Rt and the voltage Et at both ends of the element Rt. Therefore, T and H are made clear from an equation II by connecting the switch 1A to the side of the circuit 1. These values T and H are stored in an inner memory of a CPU 6. The temperature Ta of the air is identified from the resistance-temperature characteristic of the element Rt. Since constants A, B of the apparatus in the equation II can be known beforehand by a separate calibrating device, the flow rate U of the air can be calculated based on the equation II in the CPU 6.
