Title: Liquid crystal projector
Inventor: SAIKAI YOSHIKAZU
IPC: G02F1/1335
Filed: 1995-05-30
Abstract: PURPOSE: To improve the yield and color reproducibility of a liquid crystal projector by nearly equaling the liquid crystal layers in respective liquid crystal panels and providing these panels with solid-state anisotropic refractive index films to satisfy specific conditions. CONSTITUTION: White light is spectrally split into blue light of a wavelength of 0.436μm, green light of a wavelength of 0.546μm and red light of a wavelength of 0.700μm. Solid-state films having anisotropy Δn (S) of a positive refractive index are inserted between the separated three primary color light rays and three sheets of the active matrix type liquid crystal panels of a thickness (a) of liquid crystals which are the same in the anisotropy Δn (LC) of the refractive index. The thickness D of the solid-state films between the respective liquid crystal panels is set larger with the liquid crystal panels which allow the transmission of the light of longer wavelengths λ in such a manner that Δn(LC)*a/λ+Δn(S)*D/λ is kept constant.  For example, the red film 11, green film 12 and blue film 13 of the solid-state film having the anisotropy of the refractive index respectively allow the passage of red light, green light and blue light and the respective thicknesses are made smaller from the red film 11 toward the blue film 13.

Title: Incandescent lamp
Inventor: TSUKADA NAGAFUMI
IPC: H01K1/64
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To provide an incandescent lamp capable of suppressing a rash current into a filament by automatically controlling current flowing into the filament. SOLUTION: An incandescent lamp 10 comprises a resistor member 12 connected in series to a filament 60 and arranged within a bulb 54 and a temperature-sensitive switch 14 arranged in the bulb 54, connected in parallel to the resistor member 12, and having a contact 14b opened and closed by a bimetallic element 14a. The bimetallic element 14a begins to deform due to heating of the filament 60 in response to the start of supply of current, during which time the contact 14b is transferred to a closed condition to establish a short-circuit of the resister member 12 when the temperature of the bimetallic element 14b reaches a predetermined value. In this operation, a rash current into the filament 60 is suppressed, because the current is supplied to the filament 60 through the resistor member 12 in the beginning.  The incandescent bulb 10 is lighted bright after the short-circuit of the resister member 12, then this lighting state continues as long as the current is kept being supplied, because the temperature within the bulb 54 is avoided from being lowered.

Title: Pressure inspection method for vacuum heat insulation panel
Inventor: YAMASHITA HARUHISA
IPC: G01M3/36
Filed: 1992-05-25
Abstract: PURPOSE:To accurately inspect internal pressure in a vacuum heat insulation panel by inspecting the pressure inside the vacuum heat insulation panel based on whether or not the film of vacuum heat insulation panel has expanded at the part opposed to the recessed part of packing body. CONSTITUTION:When a vacuum heat insulation panel 1 is left in the air, a film 5 and inner bag 3 show a recessed shape along a recessed part 7 because the pressure is high outside a housing body 6 and low inside the body 6. When the pressure inside the panel 1 is subject to inspection, the panel 1 is housed in a vacuum container and the vacuum container is gradually evacuated. Then, the pressures inside and outside the housing body 6 of the panel 1 are balanced, so that the film 5 on the part opposed to the recessed part 7 will restore to flatened state. Thus, after it is detected that the pressure difference between inside and outside the body 6 has been eliminated and equalized, the pressure within the vacuum container is measured so that the pressure within the body 6 can be measured.

Title: Mold for forming
Inventor: TOGAWA SATORU
IPC: B21J13/02
Filed: 1983-07-22
Abstract: PURPOSE:To reduce the coating amount of mold releasing agent, releasing mold effectively by a simple structure, by keeping the air permeability only at the required place or range of porous air permeable material, while causing the other part of said porous air permeable material to be filled up. CONSTITUTION:Porous air permeable material 61 is applied to the one part of a mold. The place with the required air permeability on the mold backed up by casting, etc. is thinly coated with resin 64. After its curing, molten resin 65 is placed on the total surface of the porous air permeable material 61, and it is sucked through air holes 63 in an arrow direction from outside, whereby the porous material is impregnated with resin and is cured. Consequently, said material is caused to be filled up. As the resin 64 has been cured at suction stage, this place of porous material is not impregnated with resin, thereby keeping the air permeability of said place. Then the resin 64, 65 remained on the surface of the porous air permeable material 61 are removed. Thus, the mold is obtained. As the compressed air may be effectively blown out by keeping such air permeability at the limited place being in contact with a molded product, even the molded product having the shape with the tendency of air escape may be effectively mold released, and the coating number of the mold releasing agent may be reduced.
