Abstract: PROBLEM TO BE SOLVED: To obtain a steel sheet excellent in low magnetic field characteristics, by adding S and Sb+Sn 12 respectively in specified ranges to steel containing specified weight % of P, Si, Mn, Al and Ti, and the balance substantial Fe. SOLUTION: This silicon steel sheet contains, by weight <=0.2% P, 1 to 4% Si, 0.05 to 1.5% Mn, 0.1 to 1.5% Al, <=0.0009% S, <=0.005% Ti and 0.001 to 0.05% Sb+Sn/2, and the balance substantial Fe. In accordance with the reduction of S, its magnetic flux density slowly improves. By adding an extremely trace amount of Sb to the extremely low S material, the magnetic flux density is moreover improved. The desirable amount of Sb to be added is 10 to 500 ppm. Moreover, in the case Sb and Sn are compoundly added, the magnetic flux density also improves. Its desirable amount to be added is 10 to 500 ppm by Sb+Sn/2. It is suitable as a silicon steel sheet used for the iron core material for a large-sized motor an a compressor.

Inventor: TACHIBANA SHINYA
IPC: B41M1/10
Filed: 1985-11-20
Abstract: PURPOSE:To prevent the variation of ink transfer property and surface deformation due to the swelling of a blanket cylinder, by drying the surface of transfer blanket rubber after ink is transferred to a material to be printed and subsequently transferring the ink on the surface of the cylinder to the material to be printed through a blanket to perform printing. CONSTITUTION:The ink 5 allowed to fill the ink cell 3a of intaglio printing plate 3 is transferred to a transfer body 2 equipped with a transfer blanket having a silicone rubber layer provided to the surface thereof and the surface of the transfer body is subsequently dried and the ink is transferred to a material 4 to be printed to perform printing. That is, the solvent remaining in the blanket is evaporated and dried by air blow, heated air blow, an infrared dryer or a far infrared dryer and the ink on a cylinder surface is transferred to the blanket to perform printing. Therefore, the transfer property of the ink from the cylinder surface to the blanket is enhanced and, in the transfer of the ink from the blanket to the material to be printed, the ink is transferred to the material to be printed before the blanket reaches a swollen state and, therefore, the transfer property to the material to be printed becomes better and a printing film thickness can be secured and printing dimension reproducing accuracy is also well kept without being deteriorated.

Abstract: PURPOSE:To obtain high contrast and excellent memory characteristics by forming an element by using a substrate where a silicon monoxide obliquely vapor-deposited film is formed as an orientation control layer, and an AC electric field whose voltage is higher than a normal driving voltage between both transparent electrodes after liquid crystal injection. CONSTITUTION:A couple of transparent substrates 17 where transparent electrodes 14, electric breakage preventive layers 15, and orientation control layers 16 consisting of silicon monoxide obliquely vapor-deposited films are formed in order are put positive each other with the orientation control layer 16 in. Then ferroelectric liquid crystal 18 is injected between the transparent substrates 17 and then the AC electric field whose voltage is higher than the liquid crystal element driving voltage is applied between both transparent electrodes 14. The applied AC electric fields has large energy enough to vary the inclination of the layers, so the self-polarization can be set in the direction of the electric field (substrate normal direction) and the inclination of the layers and the twist of liquid crystal molecules are eliminated to obtain monodomains and inversion between bistable states. Consequently, a high contrast ratio and excellent bistable memory effect are obtained.

When pressure in the pressure oil pipe 8 exceeds the set pressure, pressure oil is discharged from a constant pressure relief valve 8a into a relief pipe 11 to send oil into the oil tank 4.  When a sluice T is closed in an emergency, the sluice valve 10a is opened and then an operation valve V is operated to feed oil in the accumulator 6 into a hydraulic cylinder device M.

IPC: F16K31/42
Filed: 1989-10-09
Abstract: PURPOSE:To strengthen valve closing force and miniaturize a valve by providing a main valve urged in the closing direction by a spring, a rod operating in the direction to which the main valve is opened, a diaphragm to operate the rod, and a solenoid type pilot valve for controlling the fluid working to the diaphragm. CONSTITUTION:A plunger 7 is pushed downward by a spring 10 while electricity is not conducted to a magnet coil 1, and a pilot valve 8 is closed. The pressure of fluid passing through a capillary tube 11 from an inlet port 22 does not work to a diaphragm 14, and the main valve 20 is closed by the strong force of a main spring 26. While electricity is conducted, a suction apparatus 4 inhale the plunger 7 opposing to the spring 10 to open the pilot valve 8. The high pressured fluid in the inlet port 22 works to a diaphragm 14 to open the main valve 20 through the rod 17 opposing to the main spring 17. Therefore, even if the strong main spring 26 is used for improving the closing force of the main valve 20, valve opening operation becomes easy and certain.
