Title: Epoxidation of olefin
Inventor: IWAHASHI SEIJI
IPC: B01J31/02
Filed: 1981-02-20
Abstract: PURPOSE: In obtaining an epoxy compound in high selectivity by reacting an olefin with hydrogen peroxide, to remove an activator of tetrahydrophthalic anhydride from raw reaction materials only through washing with water, by carrying out the epoxidation in the presence of tetrahydrophthalic anhydride which is reusable by recrystallizing it from washing water.  
     CONSTITUTION: In the presence of an acid anhydride shown by the formula (R 1 W R 4  is H, halogen, lower alkyl, alkenyl, or R 1  and R 4  may form methylene bond), an olefin is reacted with hydrogen peroxide in a liquid phase, to give an epoxy compound. 0.05W0.2mol acid hydride is preferably used based on 1g equivalent olefin, and when the acid anhydride is solid, it is heated and dissolved in the olefin or blended with it before adding hydrogen peroxide dropwise to the reaction system.  
     EFFECT: Since the equilibrium between the compound shown by the formula and a water-containing acid is extremely inclined to the side of the acid anhydride, the epoxidation can be carried out with a catalytic amount of the acid anhydride, and the hydrolysis of the formed epoxy compound is also suppressed.

Title: High-speed high-hardness iron-containing metal plating method of metallic material
Inventor: KAWAGUCHI JUN
IPC: C25D3/20
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To form an iron-contg. metallic film having high hardness on the surface of a metallic material by using a plating liquid having a specific compsn. and subjecting the metallic material, as a cathode, to plating at a specific current density. SOLUTION: The plating liquid includes ferrous ions, hardness imparting agents consisting of at least one kind selected from ascorbic acid and its salt and anions consisting of at least one kind selected from sulfamic acid ions, sulfuric acid ions and chlorine ions. The most important requirement for the plating liquid is to incorporate 0.001 to 0.03mol/l hardness imparting agents therein. Since the liquid has a reducing property, the ferric ions formed by oxidation of the ferrous ions in the plating treatment liquid are reduced, thereby the increase in the content of the ferrous ions is prevented. The pH of the plating liquid is adjusted to a range of 1 to 3 by the sulfamic acid, etc. The current density is specified to 10 to 80A/dm<2> . High-speed plating is not possible at the lower limit value or below and the films are liable to crack if the upper limit value is exceeded.

Title: Scroll compressor
Inventor: TAJIMA YOSHIHITO
IPC: F04C18/02
Filed: 1994-01-27
Abstract: PURPOSE:To increase speed of a compressor by providing an Oldham's joint in which a plurality of compression spaces are gradually decreased from outside to inside for compression while scrolls are rotated in the same directions for oscillations, and by reducing frictional resistance of a shaft of the scroll on the driving side for increasing peripheral speed. CONSTITUTION:When an electrically driven element 2 is rotated, its torque is transmitted to a first scroll 13. This torque is then transmitted to a second scroll 14 through an Oldham's joint 29. The second scroll 14 is relatively oscillated while being rotated in the same direction as the first scroll 13. A first shaft 17 on a driving side is fitted on an outside of a second shaft 24 for rotation. It is thus possible to form a large diameter of the first shaft which is driven by the electrically driven element 2. Frictional resistance of the first shaft is reduced to improve peripheral speed, and high speed operation of a compressor is promoted. It is possible not only to simplify a structure but also to reduce a size of the compressor.
