摘要:
The present invention is directed to a method for production of alkylene oxide polymers comprising reacting an alkylene oxide in an inert hydrocarbon solvent in the presence of a catalyst. The method of the present invention offers alkylene oxide polymers with a great commercial value and a high degree of polymerization which can be produced industrially advantageously with high reproducibility by the use of a catalyst obtained by a simple procedure of applying heat treatment to the product obtained by reacting an organic zinc compound with particular aliphatic polyhydric alcohol and monohydric alcohol.

Rolling element bores are provided in the outer circumferential portion of a disk-like main body. Each rolling element bore has an arcuate outer rim. Rollers each have a groove formed on the peripheral edge and extending along the entire circumference of the roller. The outer rim of each rolling element bore engages with the groove of the associated roller so that the roller is loosely fitted in the rolling element bore. Shafts are respectively formed on both sides of each roller. The shafts project from the center of the roller. An elastic ring is mounted on each shaft. Annular guide plates are respectively mounted on both sides of the disk-like main body so that the shafts of the rollers are supported by the guide plates.

A liquid crystal display device includes a panel having pixel electrodes arranged at intersections of a plurality of signal lines via switching elements for transmitting display data and a plurality of scanning lines for transmitting control signals, and a control circuit for controlling the panel. The liquid crystal panel is divided into first pixel regions and second pixel regions adjacent to the first pixel regions. The control circuit carries out impulse driving in which the control signals transmitted to each of the scanning lines are activated two times in one frame period for displaying an image. The control circuit writes the display data in either one of the pixel regions and writes reset data in the other pixel regions when the control signals are activated once of the two times. By writing the reset data in the pixel regions, the display data written in an immediately preceding frame are reset. In consecutive frames, the display data written in the pixel regions are always reset in one frame period. Therefore, blurring in a moving image can be alleviated. Since writing the display data and the reset data is carried out separately in the first pixel regions and in the second pixel regions, flicker is prevented from occurring in a display screen.

A display apparatus and a control method capable of preventing its user from viewing an image in an improper viewing position. The display apparatus includes: an imaging unit that captures a moving image in a predetermined range with respect to an image display direction; an image analyzer that analyzes the moving image captured by the imaging unit, and calculates a position of a target that should be guided to a proper viewing position; and a display controller that causes a display unit to perform display to guide the target to the proper viewing position when the target position calculated by the image analyzer is at an improper viewing position.

An asynchronous branching module (102) outputs transfer data received in accordance with a handshake protocol to any of branch destinations. An asynchronous arbitration module (101) merges transfer paths of the transfer data. A congestion detection module (111) receives an arbitration result signal from the asynchronous arbitration module (101) and outputs congestion information indicating presence/absence of congestion to a merge source. A congestion avoiding path calculation module (112) receives the congestion information and exclusively performs a process of storing the congestion information into a congestion information storage memory, and a process of making the asynchronous branching module (102) preferentially select, as a transfer branch destination, a branch destination generating no congestion information indicative of the presence of congestion from branch destinations leading to a destination, on the basis of the congestion information and the destination information of the transfer data.

A gas turbine, in which compressed air that is compressed by a compressor (11) is mixed with fuel in a combustor (12), the mixture is burned to produce combustion gas, and the combustion gas is provided to a turbine (13) to produce rotative power, includes: a pressurizing unit (41) that pressurizes some of the compressed air that is compressed by the compressor (11); a combustor cooling unit (42) that cools the combustor (12) with the compressed air that is pressurized by the pressurizing unit (41); and a compressed air circulation line (46) that provides the compressed air to the casing of the combustor (12). In the gas turbine, the combustor can be cooled by minimizing pressure loss of the compressed air, and degradation of the power efficiency can be prevented.
摘要:
In a power supply system, a controller is electrically connected with a plurality of switching elements of a multiphase inverter. The controller switches the plurality of switching elements on and off during a multiphase motor being activated. This converts a voltage of a first power storage device into a multiphase AC voltage so as to supply the multiphase AC voltage to the multiphase motor. This also boosts a voltage of a second power storage device to charge the first power storage device by the boosted voltage via multiphase windings of the motor. The controller switches the plurality of switching elements on and off during the multiphase motor being inactivated to thereby boost the voltage of the second power storage device to charge the first power storage device by the boosted voltage.

To eliminate the unevenness of the remaining film thickness of the wafers, and increase the polishing efficiency, reduce the running cost and enhance the yield. A CMP apparatus 1 is equipped with a polishing recipe preparing means 3 that prepares polishing conditions so that the polishing conditions such as polishing speed, polishing pressure, abrasive and the like for the wafers become optimal, a remaining film thickness forecasting means 4 that forecasts the remaining film thickness of the wafer to be polished under the polishing conditions after polishing, a remaining film thickness measuring apparatus 4 that measures the remaining film thickness of the wafer after the polishing, and a computer 6 that controls the polishing conditions on the basis of the measurement results of the remaining film thickness. Further, the computer 6 includes a calculating unit 11 that calculate the difference between the measured value of the remaining film thickness and the forecasted value thereof, and a polishing condition correcting/changing unit 13 that corrects/changes the polishing conditions so that the calculated difference becomes minimal, and thereby, the correction/change of the polishing conditions is carried out in real time.
