Title: Torque actuator
Inventor: SAWADA YASUO
IPC: F16H25/22
Filed: 1980-03-15
Abstract: PURPOSE: To simplify the manufacture of a torque actuator which converts linear motion to rotation for outputting by a method wherein there are provided spiral grooves on the outer circumferential surface of a rotary shaft and ball on the inner circumferential surface of a piston and they are connected with each other through balls.  
     CONSTITUTION: If pressure fluid is poured from a port 7 when the piston 3 is located on the side of the small diameter part 2c of a cylinder 2, the piston 3 is guided axially and moved straight leftward because it is inserted into a key groove 13 made on the cylinder 2 by a key 15 fixed on the 2nd cylinder part 10. Accordingly, the balls 19 also inserted into semi-spherical ball holes 18... protruded on the inner surface of the 2nd cylinder part 10 of the piston 3 make a straight motion and moves in the spiral grooves 17... formed on the large diameter shaft part 4d of the rotary shaft 4 and therefore the rotary shaft 4 is turned. If pressure fluid is poured from a port 6 after the piston 3 moves up to the left limit, the rotary shaft 4 is reversed.

Filed: 1985-02-22
Abstract: PURPOSE:To improve the profitability of a DRAM control circuit by using a DRAM control LSI of a smaller size with only a pair of normal access requests and then combining said LSIs with two pairs of normal access requests respectively. CONSTITUTION:When a refresh request signal RFR Q1 is supplied to an LSI1-1 at one side from the outside, a conflict occurs between the RFR Q1 and a normal access request signal AS 1.

Abstract: PURPOSE:To secure the maximum solar radiation amount with no mutual shadow produced among solar cells by turning the surface of each cell gradually to accept the rising sun in the first rising term and then to part from the setting sun in the second setting term respectively. CONSTITUTION:A rotary shaft 1 to which a solar 2 is fixed is turned to raise gradually the cell 2 to the east direction from the upright position in response to the rising sun in the first rising term of the sun. Thus the angle of the cell 2 is gradually increased and the surface of the cell 2 is turned gradually toward the sun. The cell 2 is turned in the opposite direction to that of the first rising term in the second rising term of the sun at and after a time point when the cell 2 rises up to a prescribed angle. Thus the cell 2 is gradually turned upward. Then the cell 2 is raised gradually in the west direction in the first setting term of the sun at and after a time point when the sun passes through the apex of its moving locus. Thus the angle of the cell 2 is increased and the surface of the cell 2 is gradually turned to the west in response to the shift of the sun. Then the cell 2 is turned in the opposite direction at and after the second setting term of the sun when the cell rises up to a prescribed angle. Thus the cell 2 is turned gradually in the direction where the surface of the cell 2 is turned upward with its angle reduced gradually.

Title: Method of forming semiconductor insulation film
Inventor: MATSUMOTO MICHIICHI
IPC: H01L27/04
Filed: 1990-02-14
Abstract: PURPOSE:To elevate the dielectric constant of an insulation film, and to increase capacitance by containing Al in the thermal oxide film of Si and forming the insulation film of alumina. CONSTITUTION:An Si substrate 1 is washed by using an acid on alkali solution. Consequently, particles and a heavy metal (such as Fe, Cu, Au, Cr, etc.) on the surface of the silicon substrate 1 are removed. The surface of the silicon substrate 1 is then washed by alkali solution, such as ammonia hydrogen peroxide, containing Al. Al in ammonia hydrogen peroxide water is taken into a natural oxide film formed on the surface of the Si water 1 during washing. The Si wafer 1 adsorbing Al 2 is oxidized in a dry oxygen atmosphere. Accordingly, Al remains in the oxide film of Si, and an alumina group insulation film 3 is formed.

Title: Dehydration accelerating method in vacuum filter

IPC: B01D33/06
Filed: 1980-03-18
Abstract: PURPOSE: To obtain the cake of less moisture than that in the usual method by beforehand adding a foaming agent and a capturing agent to the pulp to be filtered, in a dehydration accelerating method involving addition of a dehydration accelerator.  
     CONSTITUTION: In filtering the concentrate pulp of metallic sulfide, a foaming agent is added to the pulp, after which a dehydration accelerator is directly added in the form of liquid or mist to the filter cake surface of a vacuum filter. The addition of the foaming agent helps sticking of a coarse particles as possible on forth and increasing of coarse particle ratios in the parts to be first adsorbed to filter cloths. This results in about 1% decrease in the moisture content of the cake. In the case of hydrophilic concentrate pulp, a capturing agent is further added to make the pulp hydrophobic. This results in about 1% decrease in the moisture content of the cake in the case of, for example, lead concentrate pulp. The decreased moisture content makes handling of the pulp easy, and permits reduction in its transportation cost.
