Title: Liquid crystal display device
Inventor: NAKAMURA HIDETAKA
IPC: G02F1/1335
Filed: 1994-11-25
Abstract: PURPOSE: To greatly improve the utilization efficiency by preventing the light from a light source from being lost. CONSTITUTION: The light from the light source 1 is spectrally split by a polarization beam splitter 4 into a P and an S polarized light component and the light of the split S-polarized light component is matched with the axis of polarization of the light of the P-polarized light component by a 1/2 wavelength plate 5; and the two pieces of luminous flux are multiplexed one over the other on a hologram 7, thereby making the light of the P-polarized light component incident on the hologram 7 without any loss of the light from the light source 1 and further preventing the light from being lost by an incidence-side polarizing plate even if the incidence-side polarizing plate is interposed.  Further, the light made incident on the hologram 7 is spectrally diffused by the hologram 7 into respective wavelength components of red, green, and blue, which are converged on pixels R, G, and B of the corresponding colors of a liquid crystal cell 9, so that a color display can be made without any color filter. Even when a color filter is used, the light of a complementary color component is prevented from impinging on the color filter and a black matrix is prevented from being irradiated with light, thereby eliminating the loss of light due to the color filter and black matrix.

Title: Construction board
Inventor: WATANABE SEIICHI
IPC: E04C2/26
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To provide excellent moisture-proof performance by molding a layered product using an aluminum layer as a core layer and laminated with a paper layer to one face and a synthetic resin film to the other face, sticking the layered product to at least one face of a wooden substrate, and sticking a heat insulating material to the surface. SOLUTION: A paper layer 2, an aluminum layer 3, and a synthetic resin film layer 4 are laminated in sequence to mold a layered product S, and the paper layer 2 of the layered product S is stuck to one face of a wooden substrate 1. Since the paper layer 2 is stuck to the wooden substrate 1, an adhesive infiltrates into the paper layer 2 from the wooden substrate 1 side of the paper layer 2 and reaches an infiltration portion of the adhesive inside the paper layer 2 or a resin fused from a synthetic resin sheet when the aluminum layer 3 and the paper layer 2 are stuck together, and excellent adhesive strength is obtained.  A plate-like heat insulating material 5 made of a synthetic resin foam body such as foam polyethylene is stuck to the surface of the synthetic resin film 5 of the layered product S, thereby moisture-proof and airtight performance and heat insulating performance can be improved.

Title: Method and apparatus for regenerating hydrocarbon convertingcatalyst
Inventor: AASAA REIMONDO GURIINUTSUDO
IPC: C10G35/12
Filed: 1986-12-27
Abstract: Regeneration of a spent hydrocarbon conversion catalyst is accomplished by means of a moving bed of catalyst, where catalyst is passed through several treatment zones, in a unique regeneration vessel. The catalyst is first contacted with a hot oxygen-containing gas stream in a burning zone in order to remove coke. The catalyst is then passed into a drying zone for removal of water formed in the combustion zone by passing a hot dry air stream through the catalyst. This hot air stream is produced by exchange of heat with catalyst, thereby effecting cooling of the regenerated catalyst and by use of an air heating means located in the vessel. After passing through the drying zone, the air stream provides oxygen for combustion in the combustion zone.

Abstract: PURPOSE:To lengthen a serving life of a filter and surely remove unpleasant odor components, by setting a 2nd filter of zeolite carrying Cu ion by ion- exchange in a lower part of a 1st filter for capturing particulates. CONSTITUTION:An exhaust gas from a diesel engine 11 is led to a 1st branched pipe 21, turned to a widened diameter pipe 14, catalyst poisons e.g., tar, particulates, S, P, etc., in the exhaust gas are captured by a 1st filter carrying gamma-alumina, and at the same time unpleasant odor components with high b.p. are adsorbed, and aldehydes, etc., are adsorbed by a 2nd filter 16 of zeolite carrying Cu ion by ion-exchange. When the exhaust gas becomes high temp., desorbed unpleasant odor compositions are oxidized in the 2nd filter. Meanwhile, when particulate capturing amt. in the 1st filter reaches to a specified value, the particulates are fired by an electric heater 41 and the 1st filter 15 is reproduced.

Title: Shim
Inventor: TANIGUCHI MASAHITO
IPC: B23K1/19
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain a shim which is excellent in low abrasion property and abrasion resistance under securing durability. SOLUTION: In a shim 1 interposed between the cam 55 for the valve system device of an engine and a valve lifter 54, a ceramic member 2 and a metal member 3 are joined by brazing. Since the ceramic member 2 is arranged on the side of slide contact with the cam 55, and a metal member 3 is arranged on the side of pressure contact with the valve lifter 54, and therefore the slide contact with the cam 55 is carried out on contact with the ceramic, slide friction can be reduced. In addition, since the metal member 3 having rigidity can be arranged on the side of contact with the valve lifter 54 to receive a shock load due to a valve jump, a shim is also high in durability. Gap fitting accuracy to the top of the valve lifter can be corresponded to by the machining accuracy of the outer diameter of the metal member 3.
