摘要： In the process for preparing polyether glycol comprising (A) polymerizing tetrahydrofuran or a mixture of tetrahydrofuran and other copolymerizable cyclic ether(s) in the presence of a ring-opening polymerization catalyst comprising fuming sulfuric acid and/or fluorosulfuric acid as principal component, (B) adding water or an aqueous alkali solution to the polymerization product, and heating said reaction product under the strongly acidic condition to hydrolyze the same and (C) washing the hydrolysis product comprising polytetramethylene glycol and polyether glycol having oxytetramethylene groups as principal constituent, the polymerization of the tetrahydrofuran or the mixture of tetrahydrofuran and other copolymerizable cyclic ether(s) in the (A) step is carried out by (1) contacting the same with a ring-opening polymerization catalyst at a temperature within the range of -30.degree. C. to 10.degree. C. in the first stage, and (2) elevating the reaction temperature, when the conversion of said monomer into the polymer has reached 5% or more, to a temperature which falls within the range of 0.degree. C. to 40.degree. C. and is at least 10.degree. C. higher than the reaction temperature in the first stage and continuing the polymerization at this temperature. This process enables the effective and easy preparation of a highly functional polyether glycol having a relatively low molecular weight of about 500 to 5,000 and comprising oxytetramethylene groups as principal constituent, said polyether glycol being useful as a starting material for the preparation of polyurethanes, elastomeric polyesters, elastomeric polyamides and the like.

摘要： In a fuel injection device, a control body has a pressure control chamber, an inflow port and an outflow port. The inflow port and the outflow port are opened at an abutting surface exposed to the pressure control chamber. In the pressure control chamber is arranged a floating plate for pressing the abutting surface by a pressing surface with the pressure of the fuel to interrupt communication between the inflow port and the pressure control chamber. The abutting surface of the control body is provided with an outer opposite surface portion opposite to an outer edge of the pressing surface in a displacement axis direction of the floating plate, and the outer opposite surface portion has a special depressed portion that is depressed in the displacement axis direction and that extends along the shape of the outer edge of the pressing surface.

摘要： A method of operating a fuel cell including a fuel electrode, an oxidant electrode, and an electrolyte layer having hydrogen ion conductivity sandwiched between the fuel electrode and the oxidant electrode, so that the fuel cell generates electricity as a result of an electrochemical reaction between a fuel and an oxidant. Each time the fuel cell is started from a non-operating condition, the fuel is supplied to the fuel electrode with the fuel electrode and the oxidant electrode electrically interconnected to produce hydrogen at the oxidant electrode by provoking electrochemical reactions expressed by the chemical equations H2→2H++2e− and 2H++2e−→H2 at the fuel electrode and the oxidant electrode, respectively, reducing oxides on the oxidant electrode, using the hydrogen produced at the oxidant electrode. Then, the oxidant is supplied to the oxidant electrode to begin normal continuing operation of the fuel cell.

摘要： This invention aims to provide a method and apparatus for detecting a synchronization shift in which the synchronization shift between an original image and a reproduced image can be accurately detected even if noises are generated by a video codec or the like. An original image sent out from an image source 1 has a sine wave for synchronization overwritten thereon in a frame memory. The image on which the sine wave has been overwritten is decoded in a codec and stored in another frame memory. The two images srored. in two frame memories are simultaneously started to be read out. From the image from the other frame memory, only the sine wave is extracted in a notch filter, subjected to an offset correction in an adder, and inputted to asynchronization shift detecting unit. The synchronization shift detecting unit uses the sine wave to detect line, frame and horizontal pixel shifts. Since a sine wave is used as a synchronization marker and only the sine wave is extracted in the notch filter, the synchronization shift can be accurately detected.
摘要翻译：本发明的目的在于提供一种用于检测同步偏移的方法和装置，其中即使通过视频编解码器等产生噪声也能够准确地检测原始图像和再现图像之间的同步偏移。从图像源1发送的原始图像在帧存储器中具有用于同步的正弦波。已经覆盖了正弦波的图像以编码解码器解码并存储在另一个帧存储器中。这两个图像被扫描。同时开始在两帧存储器中读出。从另一个帧存储器的图像中，只有在陷波滤波器中提取正弦波，在加法器中进行偏移校正，并输入到异步移位检测单元。同步移位检测单元使用正弦波来检测线，帧和水平像素移位。由于使用正弦波作为同步标记，并且仅在陷波滤波器中提取正弦波，因此可以准确地检测同步偏移。

摘要： A corresponding MB2 for the left sequence is determined from the parallax vector of a coding-object MB1 of the frame Bi for the right sequence. The motion vector {circle around (2)} of the corresponding MB2 is used as an origin of the search area for finding the motion vector of the coding-object MB1. As an alternative, the motion vector {circle around (3)} of MB3 adjacent to the coding-object MB1 is used as an origin of the search area for finding a motion vector of the coding-object MB1. As another alternative, the motion vector {circle around (2)} or {circle around (3)}, whichever is higher in utility evaluation, is used as an origin. As a result, both the search area and the circuit size for detecting a motion vector can be reduced. This configuration provides a stereo video data motion vector coding apparatus small in circuit size and capable of detecting a motion vector with high accuracy.

摘要： An optical pickup includes a polarization component separation element which is formed as a unit or single piece of birefringence material. The separation element is not laminated obviating the need to carefully match the optical axes of the laminated pieces. Multiple reflections within the birefringent crystal which comprises the separation element improves the separation and resolution of the polarized components which are extracted from a laser beam reflected back off the media surface.
