Filed: 1991-08-01
Abstract: PURPOSE:To equalize display characteristics of adjacent picture elements and to suppress the generation of a longitudinal line at a division border so as to improve display characteristics by making signal line driving parts corresponding to mutually adjacent display areas opposite in specific scanning direction. CONSTITUTION:A display area is divided into plural parts and a source driving circuit 2 is also divided correspondingly into parts 2a and 2b, which are made opposite in scanning direction to scan the mutually adjacent display areas in opposite directions. In this case, there is the border of the display areas between a picture element array connected to a source bus line 11 connected to an analog switch 4an and a picture element array connected to a source bus line 11 connected to an analog switch 4b1, but the analog switches 4an and 4b1 are switches which are driven finally in one scan of the source driving circuit parts 2a and 2b and also driven substantially at the same time, so the adjacent picture elements on both sides of the border are driven substantially at the same time.

Inventor: KUME TSUNEO
IPC: H02P5/46
Filed: 1984-09-14
Abstract: PURPOSE:To drive a plurality of induction motors by an inverter by operating a main motor at no load when driving an auxiliary motor, and simultaneously operating it. CONSTITUTION:When a cutter such as a drill 13 is rotated to cut a work 7, a main shaft 4 is first stopped at the prescribed position, the shaft 4 is locked by a mechanical brake 5,and the shaft 4 and a main shaft motor 1 are disconnected by a clutch 3. When the motor 1 which becomes no load is operated,an induced voltage in response to the speed is generated. When a cutter rotating motor 12 is connected through a contactor 15 in parallel with the motor 1, the motor 12 is driven by the induced voltage. When the load is applied to the motor 12, the exciting current of the motor 1 decreases by the current, and the induced voltage drops, but if the motor 12 is sufficiently smaller than the motor 1, it does not become a problem inpractice. Thus, an inverter for driving the motor 12 can be omitted.

The soln. is again heated to form MoO3 which is then cleaned. Such operation is repeated until MoO3 having high purity is obtd. The high-purity MoO3 is dissolved with a small amt. of NH3 and a known amt. of Na, K, U, etc. is added thereto to prepare a standard sample. On the other hand, the sample liquid formed by dissolving the Mo material to be measured into a soln. mixture composed of refined nitric acid and hydrochloric acid is prepd. The absorptions of the emission line of alkali metals in both of the standard soln. and the sample soln. measured by using a flameless atomic absorption device are compared by using the calibration curve obtd. from the standard sample and the concn. in the sample to be analyzed is determined in the case of measuring the alkali metals. The fluorescent intensity, etc. of both solns. are measured and the concn. is determined by using the calibration curve in the case of measuring U. The analysis of ppb order is thus made possible.

Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To efficiently transfer data by outputting a signal to indicate that an idle cell is outputted, when the idle cell is outputted. SOLUTION: Inputted data are separated into packets with 48 bytes, one cell is generated by attaching a header by each packet and outputted to a FIFO control part 32 by an SAR part 31. The generated cell is outputted together with a signal to indicate whether the cell is the one which contains valid data or the idle cell containing invalid data by the SAR part 31. The inputted cell is judged by the FIFO control part 32, as to whether it is the valid cell or the idle cell from the inputted signal, and when it is a valid cell, it is outputted to the FIFO part 33 and is stored there. However, when it is an idle cell, it will not allow FIFO part 33 to store.

Filed: 1981-12-07
Abstract: PURPOSE:To decrease the number of memories and to improve the efficiency of memory usage, by dividing one set of memory areas into two at a read/write control circuit and using each area for access write protection information. CONSTITUTION:At write, depending that a discrimination bit in an address bit from a read/write control circuit 10 is 1, access protection data of the 1st register 14 are written in one area out of two divided areas of an S-RAM 16 and similarly, write protection data are written in the other area of the RAM16.
