Title: Liquid crystal display body
Inventor: TAKESHITA YUTAKA
IPC: G02F1/133
Filed: 1981-05-11
Abstract: PURPOSE:To increase the trailing speed of the liquid crystal, by forming a vertical magnetized film at least on one of two upper and lower substrates on which the electrodes are formed. CONSTITUTION:A vertical magnetized film 209 is formed on the surface of a substrate 206 so that the display area is set <=40%, and a transparent electrode 205 is provided on the film 209 via an insulated film 211. Then the substrate 206 and a substrate 202 containing a transparent electrode 203 are assembled together via a spacer 204 to form a cell. A nematic liquid crystal 210 having the negative magnetic anisotropy and the positive dielectric anisotropy is enclosed into the cell. Thus a liquid crystal body is obtained. The voltage is applied between the electrodes 203 and 205 to set the axis C of the crystal 210 vertical (210-b) to the electrode face. Thus the optical rotation properties is lost to obtain a dark viewfield. In case the voltage application is cut off, a magnetic field is applied to the liquid crystal by the magnetic force of the film 209. This magnetic field is used as the force that tries to turn a liquid cyrstal having the negative magnetic anisotropy toward the lateral side. Thus the liquid crystal is quickly reset to its original state.

Title: Production of vertical magnetic storage medium
Inventor: TANAKA HIDEO
IPC: C23C14/00
Filed: 1984-04-09
Abstract: PURPOSE:To maintain the specified magnetic permeability and envelope of reproduction output by providing a vertical magnetic recording film on a soft amorphous magnetic film on a substrate, blanking concentrically the substrate to form a floppy disk and annealing the disk in the magnetic field diverging radially from the center. CONSTITUTION:The resin substrate 14 delivered from a delivery roll 4 is formed with soft amorphous magnetic Co-Zr films 19, 20 on one surface thereof by an amorphous alloy target 17 in the position of a substrate holder 5 and is then formed with the vertical magnetic recording film 3 consisting of Co-Cr thereof through a shielding plate 6. A tape-shaped magnetic recording medium manufactured in such a way is blanked to a concentrical ring shape and thereafter the vertical magnetic storage medium is set between the magnets forming the magnetic field diverging radially from the center of the concentrical circle and is annealed for >=2-3hr. The direction of the axis of easy magnetization of the manufactured floppy disk is made radial from the center of the concentrical circle. The envelope of the reproduction output is thus made uniform and the magnetic permeability in the circumferential direction is maintained at the specified high value.

Title: Container of piezoelectric oscillator
Inventor: MAKUTA TOSHIKATSU
IPC: H03B5/32
Filed: 1988-03-24
Abstract: PURPOSE:To reduce the cost of parts materials and to save the man-hour by regulating the insertion position of a substrate on the internal side of an aperture edge in a metallic container, and generating a cut-up claw which is brought into contact with the earth pattern of the substrate and a bulged claw which permits the insertion of the substrate and which prevents the sneaking down. CONSTITUTION:When an oscillation circuit is integrated into the substrate 11 and it is inserted from the aperture of the metallic container 13, the bulged claw 16 permits the insertion of the substrate 11. Consequently, the substrate 11 is abutted on the cut-up claw 14 and stops. Since the substrate 11 exceeds the maximum bulge part of the bulge claw 16, the substrate 11 is prevented from sneaking down. At such a time, the cut-up claw 14 is abutted on the earth pattern of the substrate 11, and it is electrically conducted, whereby the earth potential of the substrate and that of the metallic container 13 are made equal. With pushing the substrate 11 from the aperture of the metallic container 13, it can securely be engaged and held and furthermore, electric conduction can be obtained. Thus, the cost of parts materials can be reduced and the working man-hour can be saved.

Abstract: PURPOSE:To obtain a heat exchanger with transverse fins which have inclination to make easy flowing of dew, by a method wherein the diameter of the first hair pin pipes and the second hair pin pipes are changed or the thickness of these pipes are made thin. CONSTITUTION:The diameter of the second hair pin pipes 5 are made smaller or the thickness of said pipes are made thinner comparing to the first hair pin pipes 4. Hereby, when the first and the second hair pin pipes are expanded and made in a body with transverse fins, the heat exchanger, in which fins are inclined to the rear surface B side, because of the pipe expansion rate, can be made. Namely, it is possible to make fins incline, and the flow of dew attached between fins, will be improved, and the increasement of the draft resistance of the heat exchanger due to dew collect is prevented, enabling the decreasing rate of air flow and the decrease of the faculty few.

IPC: G01N33/48
Filed: 1995-03-29
Abstract: PURPOSE: To measure the concentration of aluminum in blood accurately when blood serum is obtained from the blood by setting the content of aluminum in silica at a specified level or below. CONSTITUTION: When a coagulant is used in the measurement of aluminum in blood, content of aluminum in silica is limited within 1500ppm because the aluminum elutes into the blood to have effect on the inspection value when the content of aluminum in silica exceeds 1500ppm. Silica containing 1500ppm or less of aluminum is obtained, for example, by bringing silica into contact, for a specified time, with alkaline aqueous solution (e.g. water-soluble sodium) of specified concentration causing no corrosion of silica, removing silica by cleaning silica with water and then drying to produce powdery silica.
