Abstract: PURPOSE:To reduce the number of installed valves for adjusting the supply of hydraulic pressure to a shield jack, and provide a smooth and precise shield jack control method for a shield machine. CONSTITUTION:Shield jacks positioned near each other among shield jacks 9-1 to 9-18 are grouped and classified into an even number of blocks equal to four or more. The shield jacks within the same group are fitted with one of pressure control valves 30-1 to 30-8 at the rod side thereof. When a shield machine advances while turning, a target force point position is obtained from a target control angle formed out of the axial and advance directions of a shield machine body 1. Then, the thrust of the shield jack in the block where the target force point is positioned, is taken as a maximum value, and the thrust of the shield jack in the block at a point symmetrical position with the block where the target force point is positioned, is taken as a minimum value among all the blocks. Furthermore, the thrust of the shield jacks in remaining blocks are reduced in stages from the maximum thrust block to the minimum thrust block.

IPC: G09G3/28
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To improve discharge luminous efficiency and to suppress virtual contour by expanding a margin, by dividing one field into plural sub-fields and blocks, and maintaining a biggest weight sub-field in each block and discharging it at a different time during one field. SOLUTION: For instance, one field is composed of XGA (1024×768) divided into seven sub-field and seven blocks. A reset period is set to 100 μsec, and a priming pulse or a deletion pulse is arbitrarily impressed in this period. An address pulse width is set to 3 μsec. A maintaining frequency is 125 kHz, and a largest brightness information bit, namely, a bit of a long discharge maintaining period is set to 256 cycles and about 2 msec, and a smallest brightness information bit is set to 4 cycles. Thus, since each block displays different brightness information, respectively, in a specific sub-field, it is possible to spatially distribute the brightness gravity center.

Title: Circulation unit of ink jet recorder
Inventor: MINEGISHI TAKATOSHI
IPC: B41J2/175
Filed: 1982-11-17
Abstract: PURPOSE:To make the automatic supply of intensifier to a washing liquid feed system possible, by a method wherein intensifier is used instead of washing liquid, and the intensifier always pressurized in washing liquid supply system is sent back to an ink tank via a solenoid valve. CONSTITUTION:When an ink jet recorder operates, both an intensifier pressurizing pump 4 and an ink pressurizing pump 5 operate and the intensifier sucked by the intensifier pressurizing pump 4 from an intensifier tank 1 is always under a pressurized state in the intensifier feed system. When nozzles are washed, the pressurized intensifier is conducted to a nozzle 12 by operating a feed side three-way solenoid valve 11. When intensifier is fed, the pressurized intensifier is conducted to the ink tank 2 by operating a feed two-way solenoid valve 10. The feed amount of intensifier is settled according to the discharge pressure of intensifier pressurizing pump 4 and the operating time of feed two-way solenoid valve 10. Thus, the performance of intensifier feeder can be obtained by only adding a piece of two-way solenoid valve to the intensifier feed sytem.

Title: Boiled rich quality measuring apparatus
Inventor: MORI TAIICHI
IPC: G01N24/00
Filed: 1990-07-27
Abstract: PURPOSE:To make it possible to perform the objective, accurate, quick measurement by measuring the amount of water content based on a spin-lattice relaxation time and/or a spin-spin relaxation time, measuring the gelatinization degree based on the spin-spin relaxation time, and judging the quality based on correlation between both values. CONSTITUTION:A boiled rice sample is set in a nuclear magnetic resonance device, and a spin lattice relaxation time T1 and a spin-spin relaxation time T2 are measured. With respect to the amount of water content, the highly accurate value is obtained by compensating for both values to each other rather than measuring only one of the times T1 and T2. The gelatinization degree is measured for T2. Both values are ranked, and the ranks are displayed. Thus, the objective, accurate, quick measurement can be performed.

Filed: 1984-09-27
Abstract: PURPOSE:To prevent the upper-layer resist from being etched when etching the lower layer of a resist, by exposure to a light or x-ray through an exposure mask in the atmosphere of monomer vapor phase. CONSTITUTION:An Al film 2 is deposited on a Si wafer 1, and then the surface of the Al film 2 is coated with a lower-layer resist 3. Next, exposure to an x-ray 7 through an x-ray mask 6 is performed in a monomer gas. Then, the film 3 is etched by an oxygen ion 8 using a polymethylsiloxane film 5 as a mask. At this time, the film 5, the upper-layer resist, is highly resistant to the ion etching, so that there is almost no decrease in the film thickness. Then, the film 2 is etched using a patterned double-layer resist film 9 as a mask. Finally, the film 9 is removed to obtain a patterned Al film 2'. By this method, a resist can be formed which has high etching selectivity with the lower layer of a resist.

Abstract: PURPOSE:To improve the heat-insulation and reduce the loss of sensible heat while keeping the pressure resistance by forming a vacuum heat-insulation space between an outer tube and a thin-walled inner tube filled with a metal hydride and holding both tubes with a spacer. CONSTITUTION:A thin-walled inner tube 4 is inserted into an outer tube 2 having similar shape to obtain a double-tube structure. A metal hydride 5 is filled in the inner tube 4 and a filter tube 6 and a heat-exchanger 7 are placed in the inner tube in a state embedded in the metal hydride 5. The filter tube 6 is permeable to H2 and impermeable to the finely pulverized metal hydride 5 and is connected to an H2 gas inlet and outlet tube 8 extending through an end plate 3. The heat-exchanger 7 is an inlet and outlet tube of a heating or cooling medium furnished with fins 9 and is passed through the end plate 3. A ring-shaped heat-insulation spacer 11 is fitted to the outer circumference of the inner tube 4 to form a space 12 between the inner tube 4 and the outer tube 2. The space is maintained in vacuum. There is little loss of sensible heat from the container 1 because of the thin wall-thickness of the inner tube 4. High heat-insulation is attained by the presence of the space 12 and the pressure resistance of the inner tube 4 can be assured by the spacer 11.
