    摘要： A decoupling device for decoupling a high-frequency noise wave in a digital circuit is formed as a line device including a portion of a semiconductor substrate, an insulator film formed thereon as a gate oxide film, and an interconnect line formed thereon as a gate electrode. The line capacitance between the interconnect line and the semiconductor substrate is 100 pF or above, whereby the decoupling device effectively decouples the electromagnetic noise wave generated by a switching device in a frequency range between 10 and 1000 GHz.

    摘要： An information-provision apparatus that is capable of easily changing the format of display data without the risk due to changes of the program since it is not necessary to change the program. A format-separation unit separates basic format data, to which part information is attached that indicates a starting position and ending position of each structural unit of the format, according to the part information, and stores the format of a format database in a format-memory unit. Next, a format-acquisition unit receives search conditions from an information terminal, and acquires each of the structural units corresponding to those search conditions from the format-memory unit. A display-data-generation unit inputs the data from the search results acquired from the database into the variables of the structural units acquired by the format-acquisition unit and generates display data, and a send unit sends the generated display data to the information terminal.

    摘要： A steam turbine includes a rotor which extends along a longitudinal axis and having at least two different pressure turbine portions disposed around and along the rotor. Each of the turbine portions has multiple stages. A casing encloses the rotor and has at least one steam inlet. A dummy ring is provided stationarily around the rotor to separate and seal between the two different pressure turbine portions. The dummy ring defines nozzle chamber for receiving the steam from the steam inlet port and a plurality of nozzles for directing the steam from the nozzle chamber toward the higher pressure turbine portion. The dummy ring and the casing define a space therebetween. The space is fluidly connected to the higher pressure turbine portion. A steam passage extends between the space and a steam passage downstream of the last stage of the higher pressure turbine portion. The steam passage allows the steam within the space to flow to the steam passage downstream of the last stage of the higher pressure turbine portion to cool the casing.

    摘要： Provided is an industrially useful process for producing an optically active 2-hydroxy-4-arylbutyric acid or its ester. An optically active acyloxysuccinic anhydride is reacted with an aromatic compound in the presence of a Lewis acid to produce an optically active 2-acyloxy-4-oxo-4-arylbutyric acid. The 2-acyloxy-4-oxo-4-arylbutyric acid is converted to an optically active 2-acyloxy-4-arylbutyric acid through catalytic reduction. The 2-acyloxy-4-arylbutyric acid is hydrolyzed in the presence of an acid or an alkali to produce an optically active 2-hydroxy-4-arylbutyric acid. The 2-hydroxy-4-arylbutyric acid is reacted with an alcohol in the presence of an acid to produce an optically active 2-hydroxy-4-arylbutyric acid ester.

    摘要： The present invention relates to a leak reducing structure in a steam turbine having high pressure, intermediate pressure, and low pressure turbine sections in a single casing, in which steam leaking from the high pressure side to the intermediate pressure side is recovered to be used effectively. The high pressure, intermediate pressure, and low pressure turbine sections are arranged along a rotor in an external casing. High-pressure steam from a high-pressure steam inlet port passes through a nozzle chamber formed integrally with a dummy ring, and flows into the high pressure turbine section to do work. On the other hand, some of high-pressure steam attempts to leak from a seal portion of the dummy ring to the intermediate pressure turbine section side. However, the leaking steam flows from point X of an external pipe to point Y on the high pressure side to be recovered. Point X is set so as to be a slightly higher pressure point than point Y, and the difference in pressure is regulated by a pressure regulating valve. Therefore, the leaking high-pressure steam is recovered and used effectively, thereby preventing the decrease in performance.

    摘要翻译： 本发明涉及一种具有高压，中压和低压涡轮机部分的蒸汽轮机中的从低压侧泄漏到中压侧的蒸汽的泄漏减少结构，其中单个壳体中的蒸汽被有效地利用 。 高压，中压和低压涡轮机部分沿外壳中的转子布置。 来自高压蒸汽入口的高压蒸汽通过与虚拟环一体形成的喷嘴室，并且流入高压涡轮部分以进行工作。 另一方面，一些高压蒸汽试图从虚拟环的密封部分泄漏到中间压力涡轮机部分侧。 然而，泄漏的蒸汽从外部管道的点X流向要回收的高压侧的点Y。 点X设定为比点Y稍高的压力点，压力差由压力调节阀调节。 因此，泄漏的高压蒸汽被有效地回收和使用，从而防止性能的降低。
