Title: Sensing method for liquid boundary layers in tank
Inventor: NAKAMURA JIYUN
IPC: F17C13/02
Filed: 1981-06-28
Abstract: PURPOSE:To sense the boundary position of liquid layers by measuring the change of buoyancy applied to a weight in the depth direction of liquid. CONSTITUTION:In a tank 1 containing two liquid layers with different densities rho1, rho2, a weight 5 having a density rho3 which is a little larger than the density rho2 is hung by a thin wire or a tension rod 6. Then the weight is measured by a weight meter 7 while the wire 6 is pulled up gradually. When this weight 5 shifts from the lower 3 to upper layer 2, a change in buoyancy at the boundary 4 owing to difference of densities rho1<rho2, will change the indication of the weight  meter 7. This position is found from the length of wire 6 to detect the position of the interface of two liquids.

Abstract: PURPOSE:To obtain a material for constituting molten carbonate type battery material having excellent in resistance to molten carbonate, by a method wherein an Fe-Cr-Al alloy is heated at a limited temp. and an oxide layer comprising Al2O3 is preferentially formd on the surface thereof. CONSTITUTION:When an Fe-Cr-Al alloy is heated at 1,000-1,220 deg.C in the air to be preliminarily oxidized, three kinds of oxides are formed as shown by formula I but gradually replaced with Al2O3 by formulae II, III. The replacement reaction speed is dependent on a temp. and a time, and an oxide layer having >=50% ratio of Al2O3 relative to all oxides is formed on the surface of the alloy. Thus formed Al2O3 layer has excellent resistance to molten carbonate even in an oxidative or a reductive atmosphere.

Title: Liquid crystal display plate for projection device
Inventor: NISHIKAWA AKIRA
IPC: G02F1/133
Filed: 1986-04-30
Abstract: PURPOSE:To omit an independent reflecting plate by providing substrates where electrodes are formed to the front and rear surfaces of liquid crystal, and using a transparent electrode as the electrode on the front surface side and forming a reflecting surface on the substrate on the rear surface side. CONSTITUTION:When a light beam from a light source 11 is projected on a liquid crystal display plate 9 and electrodes 4 and 5 are selected and applied with a voltage, dots are formed on liquid crystal to display an image. At this time, a condenser lens 12 diverges the illumination light from the light source 11 almost to the contour of the liquid crystal display plate 9. This illumination light is converged by the converging Fresnel lens 7 without any waste and projected on the liquid crystal 1, and the light is reflected by the electrode 5 and transmitted through the liquid crystal 1 again; and the light is converged by the converging Fresnel lens 7 to illuminate almost to the overall diameter of an image forming lens 13, and then projected on a screen 7. The electrode 5 contacts the rear surface of the liquid crystal 1, so a reflected image never shifts in position and the electrode 5 is utilized as the reflecting surface, so the reflecting plate need not be provided independently and have its installation position adjusted.
