IPC: F28D20/00
Filed: 1982-11-16
Abstract: PURPOSE:To enable the titled tank of simple structure to withstand a thermal stress by a method wherein an inner storage tank provided with a heat insulating material is arranged concentrically within an outer storage tank provided with a heat insulating material. CONSTITUTION:A low temperature side heat medium SL is supplied into a heat exchanger 20 from a pipe 19 so as to exchange heat with excess steam supplied into the heat exchanger 20 from a steam plant through a steam pipe 27.

Title: Production of laminated sheet for liquid crystal display panel and production of liquid crystal display panel
Inventor: SUZUKI HIDEAKI
IPC: G02F1/1333
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To smoothly perform precision work in the production process of a liquid crystal display panel by laminating a light-transmitting plastic film while heating and pressurizing with an adhesive layer to an adhesive sheet prepared to be easily released from the light-transmitting plastic film. SOLUTION: A light-transmitting plastic film 15 is laminated while heating and pressurizing with an adhesive layer 14 by using a roll 18 to an adhesive sheet consisting of a base resin sheet 13 and an adhesive layer 14. Then a light-transmitting metal oxide electrode 16, alignment film 17 or the like are formed on the light-transmitting plastic film 15 to obtain a laminated body. When the alignment film 17 is formed, the layers are kept at 100 to 200 deg.C for 1 to 3 hours. However, since bubbles in the adhesive layer 14 are removed by the roll 18, the adhesive layer 14 and the light-transmitting plastic film 15 are firmly adhered to each other even at that high temperature. As a result, precision work in the production process can be smoothly performed.

Title: Microfilm reader
Inventor: HIDESHIMA TAKAHIRO
IPC: G03B21/11
Filed: 1993-07-20
Abstract: PURPOSE:To improve the S/N and the detecting accuracy of a photodetector for detecting a mark for detection even when microfilm is electrostatically charged by obtaining the difference of the outputs of two photodetectors, such as a photodetector and another photodetector which is optically shaded from light but not electromagnetically shaded, with respect to the microfilm. CONSTITUTION:The photodetector 54 has the same characteristic as the photodetector 52, is arranged adjacently to the photodetector 52 and shaded, from the light by a light shading plate 56 which optically shades the photodetecting part thereof from the light but does not electromagnetically shade it. Since the incidence of the light is only intercepted on the photodetector 54, only a noise component by the charge on the film 18 is detected. Therefore, a subtracter 58 subtracts an output signal (b) corresponding to the noise from an output signal (a), so that only the pulse signal (c) is obtained. In this microfilm reader, the presence or absence and the length of the mark for retrieval are discriminated based on the output (a-b)=c from the subtracter 58, whereby the S/N and the detecting accuracy are improved.

Title: Semiconductor device and manufacture thereof
Inventor: YAMAMORI AKIYOSHI
IPC: H01L21/822
Filed: 1988-08-11
Abstract: PURPOSE:To sparsely concentrate an electric field, and to prevent the breakdown strength of an insulating film from decreasing and a leakage current from increasing by employing polysilicon patterned in a shape for drawing a circular arc at the upper end of its section. CONSTITUTION:When a polysilicon stack capacity, for example, is employed, the shape of both upper ends of a lower polysilicon electrode draws a circular arc. A TaOx film having 80Angstrom  of thickness is employed as a capacity insulating film 5. With a structure of this shape, the leakage current of a square-shaped structure stack capacity (capacity film is of TaO film having 80Angstrom  of thickness) is 10<-7>A/cm<2> at the time of application of 3V, while it is remarkably reduced to 10<9>A/cm<2> at the time of application of 3V. Further, when an interlayer insulating film is formed on a polysilicon upper electrode 11, since a groove between the capacities is smooth, no void is generated. Thus, an electric field is sparsely concentrated, and it can prevent the breakdown strength of the insulating film from decreasing, and leakage current from increasing.

When the specified meteorological conditions are reached according to the measurement made by a meteorologic observing device 8, contacts 9a and 9b are opened and closed. respectively, and changing-over takes place from the load setting device 7a into the other 7b. Thereby a steam turbine 4 is controlled with the load setting signal which does not present any problem in terms of environment.
