Title: Constructing method of building subsurface structure
Inventor: OKIMOTO MASAYUKI
IPC: E21D13/00
Filed: 1991-03-15
Abstract: PURPOSE:To decrease the variation of the ground water levels of up-and-down streams positively, to realize safe efficient operation regardless of the depth of a ground, to reduce construction cost and to build the subsurface structure of a building economically when the subsurface structure is constructed. CONSTITUTION:Water-permeable continuous underground walls 14a, 14b are frozen and cut off through a muddy-water excavation method and a groundwater flow is interrupted temporarily, thus conducting desired ground excavation, then constructing a subsurface structure 13. The frozen water-permeable continuous underground warms 14a, 14b are thawed, and the groundwater flow is restored. The variation of the ground water levels of up-and-down streams with the construction of the subsurface structure 13 is reduced. Accordingly, the water-permeable continuous underground walls are frozen and cut off, the groundwater flow is interrupted temporarily and the ground can be excavated, thus safely carrying out excavation work efficiently without the possibility of spring water and the collapse of a wall surface.

Title: Full/reduced water alarm in priming tank
Inventor: YAGI KAORU
IPC: E03B11/16
Filed: 1994-05-09
Abstract: PURPOSE:To remove projected parts from the upper part of a priming tank and to reduce the whole height of the priming tank by fixing an electrode rod and a holder for a full/reduced water alarm in priming tank. CONSTITUTION:A mount (h) for fixing the holder (d) for holding the electrode rod (c) is arranged in the priming tank (f). The holder (d) with the rod (c) is mounted on the mount (h) and fixed to the mount (h) with a clamping nut (g). When the upper end face of the tank (f) is covered by a priming tank cover (a), the full/reduced water alarm (d) can be stored in the tank (f). Since the alarm (k) having a detecting function for checking the water level of the inside of the tank (f) is set up in the tank (f), a conventional steel-made box is made unnecessary and the height of the holder (d) exerts no influence upon the overall height of the tank (f), so that the overall height of the tank (f) and that of a fire pump unit can be suppressed to low levels.

Title: Convergence device
Inventor: YAMAMOTO KAZUYASU
IPC: H04N9/28
Filed: 1979-09-18
Abstract: PURPOSE:To lessen the deterioration of focusing by making the number of turns of a blue lateral coil less than that of a correcting coil and by fixing their winding directions so that magnetic forces of both the coils will oppose to each other in the diameter direction on the circumferential surface. CONSTITUTION:The number of turns of blue lateral coil 8 is made less than that of correcting coil 9. Then, red and green electron beams R and G are made to agree at point W through a radial static coil and blue electron beam B is made closer to point W by radial static coil. Next, as beam B is laterally moved by varying currents of blue lateral coil 8 and correcting coil 9 to agree with point W, beams R and G move toward beam B and focus on point W''. Therefore, since only the small correction extent of beam B is required, the deterioration of focusing is improved and its adjustment is facilitated.

Title: Semiconductor device
Inventor: YAMAZAKI SHIYUNPEI
IPC: H01L31/04
Filed: 1982-07-12
Abstract: PURPOSE:To reduce manufacturing cost of solar cells by producing a P-I-N junction on a substrate and by restricting crystal particle size of an intrinsic layer not more  than five mu. CONSTITUTION:Molybdenum 2 is deposited on a glass plate 1 and polycrystalline silicon layers 5,6 are produced on it by gas phase growth under reduced pressure or by glow discharge to produce comb-shaped opposed electrodes 7 and an outlet terminal 8. It is more advantageous to use the gas phase growth under reduced pressure  than to use the glow discharge for production of the layers 5,6 owing to smaller crystal grain boundaries and less recombination centers. When the gas phase growth is employed, it is easier for manufacturing process to use SiH4 than to use SiCl2 or SiCl4.  When polysilicon is formed by gas phase growth under reaction pressure of five torr  and at thermal decomposition temperature of 650 deg.C, produced particle diameter can be  0.1mu. No recombination centers can theoretically be produced in polycrystalline semiconductors, but practically only polycrystals having lower density of recombination centers  can be produced depending on types of manufacturing procedures employed. Thin  layers of uniform polycrystalline films having less pinholes can be formed by such processes and electric charge formed by the p-n junction or P-I-N junction can be diffused  rapidly to electrodes 2,7, i.e. solar cells of good quality can be produced at lower cost.
