Title: Vinyl leather
Inventor: OGAWA TAKESHI
IPC: B32B5/18
Filed: 1988-12-28
Abstract: PURPOSE:To provide a vinyl leather of favorable feel, embossable without destructing the expanded layer, made up of a surface layer, expanded layer and substrate layer with the expanded layer consisting of a specific crosslinkable flexible vinyl chloride resin. CONSTITUTION:A release carrier is coated with e. g. a nonexpandable type vinyl chloride resin paste followed by gelation to form a surface layer. The resultant layer is then coated with a second paste prepared by incorporating (A) a plasticizer such as dibutyl phthalate, a compound, as crosslinking agent, having in the molecule isocyanate or carboxyl group, and a foaming agent in (B) a crosslinkable vinyl chloride resin consisting of a copolymer of vinyl chloride and comonomer having in the molecule hydroxyl or carboxyl group, followed by gelation. Thence, the resulting product is laminated, through an adhesive, with a substrate layer of knit fabric comprising natural or synthetic fiber followed by heating and expansion and then releasing the release carrier to form a vinyl leather, whose surface is then embossed to form uneven pattern, thus obtaining the objective final vinyl leather with favorable feel.

Title: Method for removing tailings in punching fabrication
Inventor: OTA YOSHIHISA
IPC: B31B1/14
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To simplify and make highly efficient a method for removing tailings from a punched- out part by pressing a half-cutting blade into the base material layer of a laminate consisting of a separating paper laminated on the printing face after a peeling varnish is printed on the part other than the part to be punched out on the second surface of a base material to be punched out, from the first surface of the base material, and peeling the separating paper from the base material. SOLUTION: A peeling varnish 13 is printed on the part of a laminate other than the part 11a to be punched out on the second surface of the base material 11 and the second surface of the base material 11 is laminated to a separating paper 15 using an adhesive layer 14. The laminate is processed using a punching machine in such a manner that a half- cutting blade penetrates only the part 11a to be punched out of the base material 11 from the first surface side of the base material 11 to reach the adhesive layer 14 and the separating paper 15 remains as it is without being punched out.  After the punching-out process, a peeling varnish-printed part 13 is easily peeled and the part 11a to be punched out without the printed peeling varnish adheres to the separating paper 15 and at the same time, removes tailings resulting from the punching-out process, when the separating paper 15 is released from the base material 11. Thus it is possible to remove the tailings from the punched-out part 11a simply and efficiently.

Title: Projection type display device
Inventor: SHIKAMA SHINSUKE
IPC: G02B27/28
Filed: 1989-12-22
Abstract: PURPOSE:To multiply the quantity of light transmitted through the polarizing plate on the incident side of a liquid crystal light valve and to realize a high-brightness projected image by providing an optical means for converting non-polarized illuminating luminous flux which is emitted from a light source to linearly polarized light having a polarizing direction which should be made incident on the liquid crystal light valve. CONSTITUTION:The illuminating luminous flux 2 which is emitted from the light source 1 is in a non-polarized state and is separated to reflected S polarized light 30 and transmitted P polarized light 33a by the joint surface 20a of a polarizing and separating means. The reflected S polarized light is made incident on a polarizing and rotating means 21. The means 21 is constituted of mirrors 21a and 21b which are orthogonally crossed and emits the light after rotating the polarizing direction of the incident light by 90 deg.. Therefore, the S polarized light 30 made incident on the polarizing and rotating means is emitted as the P polarized light 31, which is transmitted through the polarizing and separating means 20 still as the P polarized light, reflected by an optical path conversion means 23 and made incident on the liquid crystal light valve 3 through a condenser lens 10 as the linearly polarized light 33b in the same polarizing and advancing directions as those of the transmitted P polarized light 33a. As a result, light energy about twice as much as in conventional practice is made incident on a liquid crystal layer and contributes to the display of an image.

Title: Method of detecting vehicle model and washing vehicle in car washing machine
Inventor: SUYAMA HIKARI
IPC: B60S3/06
Filed: 1994-12-15
Abstract: PURPOSE: To simply and precisely detect a model of a vehicle with no use of several photoelectric switches and a memory device having a large capacity and to wash a vehicle with little left unwashed, by calculating an inclined angle of the upper surface of a vehicle body from a detected vehicle height and a position on travelling so as to determine a vehicle model. CONSTITUTION: When a washing unit body 1 comes to a predetermined position during washing, a light path between a light emitter 14a and a light receiver 14b of a photoelectric switch for detecting the lower part of a vehicle body is shut off so as to detect a vehicle body. During the progress of washing, photoelectric switches 15a, 15b detect the vehicle body. At this time, an inclined angle θ1 exhibiting a shape of the front part of the vehicle body is calculated from differences ha between the heights h1 of the photoelectric switches 14a, 14b and the heights h2 of the photoelectric switches 15a, 15b and a distance La between a position Y1 and a position Y2 with the use of an expression. As a result, if thus obtained angle θ1 is, for example, greater than a predetermined angle, it is determined that the automobile A has a wagon type.  Thus, a washing brush 8 is raised to avoid making contact with the front part of the vehicle body while washing the same.
