Title: Method for separating indene from raw material flow containing indene mixed in other material
Inventor: HAAMAN EI JINEN
IPC: C07C13/465
Filed: 1989-05-02
Abstract: PURPOSE: To selectively adsorb and separate indene from a raw material mixture containing alkyl aromatex, unsaturated alkyl-substituted aromatex and indene by treating the mixture with X- or Y-zeolite exchanged by Na or K.  
     CONSTITUTION: A raw material mixture containing 30 to 80 wt.% of indene, alkyl aromatex and unsaturated alkyl-substituted aromatex is treated with X- or Y-zeolite exchanged by Na or K at 20 to 100°C for selectively adsorbing indene. Then, it is treated with a desorbing agent selected from the group consisting of benzene, halogen and/or alkyl-substituted single ring aromatex and a mixture thereof (such as toluene) for desorbing and separating indene. It is important to keep the water content in zeolite at 8 wt.% or less, preferably at 4 to 7%. By this process, highly pure indene can be obtained economically.

Abstract: PURPOSE:To prevent deterioration of the color development density of a cyan color image by reducing an amount of a high-boiling organic solvent in an emulsion containing a specified cyan coupler to <=0.3wt% of the total amount of the cyan coupler. CONSTITUTION:The cyan coupler is represented by the formula shown on the right in which R1 is -CONR5R6, -NHCOR5, -NHCO2R7, -NHSO2R7, -NHCONR5R6, or -NHSO2NR5R6; R2 is a group substitutable on a naphthalene ring; m is an integer of 0-3; R3 is a monovalent organic group; X is H or a group to be released by the coupling reaction with the oxidation product of the aromatic primary amine color developing agent; each of R5 and R6 is independently H, an aliphatic group, aromatic group, or heterocyclic group; and R7 is an aliphatic group, aromatic group, or heterocyclic group. The emulsion layer containing said cyan coupler contains the high-boiling solvent at most in an amount of <=0.3wt% of the total amount of the cyan coupler, thus permitting the cyan color development density not to be deteriorated, at the time of processing with a bleaching solution or bleach-fixing solution weak in oxidation capacity.

IPC: G02B17/00
Filed: 1979-09-07
Abstract: PURPOSE: To miniaturize a lens system by using a reflecting surface and to maintain F number at an ordinary extent and correct various aberrations by giving two numerical limitations to the optical specifications of the lens system, in a lens for copying used near unmagnification.  
     CONSTITUTION: The lens systeim is constituted by the three groups disposed with the positive meniscus 1st lens of which the convex face is directed to the object and image side, the biconcave and negative 2nd lens, and the biconvex and positive 3rd lens of which the back surface is a reflecting surface. If in this way the concave reflecting surface is used, Petzval sum may be decreased but the meridional image plane becomes extremely over; therefore the numerical limitation 5f<|r 6 |<8f is given to the 6th refractive surface r 6  to improve astigmatism. Further, the radius r 2  of curvature of the 2nd refractive face is made 0.5f<r 2 <2f in order to correct the astigmatism of higher order. In this way, the unmagnification copying lens of F5.6, 50°W60° angles of view, 0.1fW0.14f of overall length and corrected various aberrations may be obtained.

Abstract: PURPOSE: To obtain a decorative plate presenting an excellent cubic pattern and suitable as the surface of a wall, ceiling and the like by a method wherein a sheet prepared by printing the pattern on the surface of a colored substrate sheet and further printing thereon a transparent convex pattern is laid on and stuck to a base plate in layers.  
     CONSTITUTION: A pattern 3 is formed on the surface of a substrate sheet 1 of paper, a resin film or the like colored fittingly as occasion calls by a photogravure, an offset, etc. and thereon a transparent convex pattern 4 is formed by using transparent paints by a method of screen printing or photogravure. After the transparent convex pattern 4 is dried up or while it is not yet dried up, the whole surface thereof is finally coated with (half-)transparent coating, which is dried to form a (half-)transparent convex protection layer 5. Thus, a facing sheet P with the convex pattern on the surface thereof is obtained and this is laid on and stuck to the surface of a base plate 6, such as plywood and a metal plate. The pattern 3 can be seen through the coating film forming the transparent convex pattern 4 formed thereon, and since the pattern in the part looks embossed more than in the other part, giving deep feeling and the tone of color itself is displayed lightly, the effectiveness in design is increased.

Title: Washbowl
Inventor: AZUMA YOSHIHIKO
IPC: C08J5/00
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To improve a surface appearance and shock resistance by forming a resin composition of a thermoplastic polyester resin and a resin containing a crystalization accelerating agent and an epoxy group, made of specified parts by weight. SOLUTION: A resin composition made of a 100 pts.wt. thermoplastic polyester resin and a 0.5 to 5 pts.wt. crystalization accelerating agent or a resin composition made of a 100 pts.wt. thermoplastic polyester resin, a 0.05 to 5 pts.wt. crystalization acceleration agent, and a 1 to 30 pts.wt. epoxy group is molded. The polyester resin is chemical resistant and optionally colorable, so it has a good appearance design property. Then in mixing the crystalization accelerating agent, if its amount exceeds 5 pts.wt. in relation to 100 pts.wt. of the polyester resin, the polyester resin tends to degrade. If it is less than 0.05 pts.wt., the degree of crystalization is slightly lower and its surface appearance improvement effect against a rib shrink is lost. Then use of a resin composition containing a 1 to 30 pts.wt. epoxy group-containing resin provides a more shock resistant washbowl.
