Title: Polarized light conversion body, liquid crystal device using it, electronic equipment and projection display device
Inventor: KUBOTA KANEMITSU
IPC: G02F1/1335
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To efficiently convert incident external light to unidirectional polarized light instead of a polarizing plate causing the loss of incident light quantity by converting the light having a second polarization direction to the light having a polarization direction almost coinciding with a first polarization direction. SOLUTION: The incident external light is passed through the lens part 11 and the light guiding part 13 of a condensing body 1 and mainly condensed at a condensing part 12. Besides, it arrives at a polarized light separation part 2a. Then, the X polarized light out of the incident external light is transmitted through a reflecting polarizer 4 and emitted downward. On the other hand, the Y polarized light is regularly reflected by the reflecting polarizer 4a and advanced in a right direction. Besides, it is regularly reflected again by the reflecting polarizer 4b being adjacent on the right and advanced downward. Then, it arrives at a double refraction plate 5a. Since the plate 5a is provided with the function of a λ/2 plate, the Y polarized light is converted to the X polarized light and emitted to the downside of a polarized light conversion body 50.  Besides, since the laminating surface of the polarizers 4a and 4b and a transparent plate 3 are arranged to be inclined with respect to the upper and the lower surfaces of the separation part 2a, the Y polarized light is converted to the X polarized light and efficiently emitted in a lower direction from the lower surface of the conversion body 50 thereafter.

Filed: 1984-11-09
Abstract: PURPOSE:To raise the etching magnification, and to increase the mechanical strength by using an AC current of a specified frequency, when making the AC current flow to a metallic foil and converting it to a roughened surface. CONSTITUTION:In an etching method for making an AC current flow to a metallic foil and converting the metallic foil to a roughened surface, an AC current whose frequency is <=2Hz is used. When the frequency of the AC current is low, an effect of the AC current and an effect as a DC current are joined together, a comparatively minute and tunnel-shaped etching pit does not pass through the metallic foil, and the metallic foil is etched in a state that the core is left. Therefore, even if this metallic foil is brought to a chemical conversion treatment and an oxide film is formed on its surface thereafter, the etching pit is not closed up and a sufficiently high electrostatic capacity is obtained, the mechanical strength can be increased, and a metallic foil which is suitable for an aluminum electrolytic capacitor, etc., is obtained.

IPC: B29K105/04
Filed: 1992-08-11
Abstract: PURPOSE:To provide a method for forming an interior component for a vehicle comprising a skin layer and a foamed layer in the uniform thickness. CONSTITUTION:A resin sheet 10a is formed by laminating a skin, a foam layer and a foamed layer. The resin sheet 10a is set in a projected mold 60 in the state of facing the foamed layer side of the resin sheet 10a to the projected mold 60. At that time, a thermoplastic resin film 18a is interposed between the foamed layer of the resin sheet 10a and the projected mold 60. As the thermoplastic resin film 18a has no rough surface unlike the foamed layer, the film slides on the projected mold 60 and works in a manner of stretching the resin sheet 10a in the uniform thickness when shaping is carried out on a molding face 62 by the projected mold 60 by the arrangement. Thus the resin sheet 10a is preshaped in uniform thickness manufactured into a product of uniform wall thickness by vacuum molding.

Title: Superconducting rotor
Inventor: MORI HIDEAKI
IPC: H02K55/04
Filed: 1990-09-06
Abstract: PURPOSE:To obtain a superconducting motor, which can operate stably without causing quenching, by forming a refrigerant path in a column separating insulator such that the exposing ratio of a superconductor to the refrigerant path is smaller for the axial groove than for the circumferential groove thereby making uniform the cooling capacity of the refrigerant at each part of a winding structure and suppressing temperature rise of the refrigerant. CONSTITUTION:Annular grooves 2 are formed in the outer surface of a winding supporting tube 1. A winding structure 3 comprising a superconductor 12 and an electric insulator provided with a refrigerant passage is contained in the groove 2. Thermal transmission of the refrigerant at the axial winding part, where the superconductor 12 extends in parallel with the center of rotation of the winding supporting tube 1, is lower than that at the circumferential winding part where the superconductor 12 extends in the circumferential direction. Exposure rate at the axial winding part is thereby set larger than that at the circumferential winding part by an amount corresponding to the difference of thermal transmission. According to the constitution, entire winding structure can be cooled uniformly and a superconducting rotor can operate stably without causing quenching.
