Inventor: KUSUDA MIKIO
IPC: B01J31/00
Filed: 1986-04-03
Abstract: PURPOSE:To advantageously obtain the titled substance useful as a raw material for heat-resistant polymers in a short time without forming water as a by- product, by subjecting 4,4'-(diphenoxycarbonyl)diphenyl ether to the Fries rearrangement under specific temperature condition using methanesulfonic acid as a reaction medium. CONSTITUTION:4,4'-(Diphenoxycarbonyl)diphenyl ether is reacted in the presence of a methanesulfonic acid at a temperature within the range of 60-160 deg.C to afford the aimed compound. The ratio of the amounts of the methanesulfonic acid to the raw material 4,4'-(diphenoxycarbonyl)diphenyl ether used is within the range of normally 1-200mol based on 1mol raw material. The above- mentioned raw material is synthesized by, e.g. reacting 4,4'-diiododiphenyl ether with carbon monoxide and phenol in the presence of a catalyst containing a transition metal compound.

Title: Manufacture of silicon carbide semiconductor device
Inventor: FURUKAWA MASAKI
IPC: H01L21/338
Filed: 1989-03-27
Abstract: PURPOSE:To obtain a silicon carbide semiconductor device without causing element characteristics to deteriorate up to a specified high temperature region by using the ion implantation method for forming an electrical insulating layer. CONSTITUTION:Boron ions are implanted into the surface region of a undoped SiC single-crystal layer 2 two times by using the ion-implantation device, thus forming a B ion-implantated layer 3. Then, thermal annealing treatment is performed in an Ar atmosphere to activate the B ion implantated layer 3, thus forming a high-resistance SiC single-crystal layer (electrical insulating layer) 4. In the high-resistance SiC single-crystal layer 4, any decrease in resistivity is hardly observed over a wide temperature range from room temperature to, for example, about 500 deg.C with a sufficient performance as an electrical insulating layer. Then, an undoped SiC single-crystal layer is allowed to grow on the electrical insulating layer 4 by the CVD method (vapor growth method) for forming a channel layer 5, thus improving rectification characteristics of the electrical insulating layer 4 and the channel region 5 from room temperature to about 500 deg.C.

Abstract: PROBLEM TO BE SOLVED: To decrease the amt. of dust produced when two kinds of solid processing agents are packaged in one packaging material by specifying the difference in the frictional coefft. in the package of two kinds of tablets which constitute the solid processing agents. SOLUTION: In the package of a solid processing agent for a silver halide photographic sensitive material, the solid processing agent is prepared by forming two kinds of tablets in 0.5 to 30g weight range and controlling the difference in the frictional coefft. in the package of the two kinds of tablets to 0 to 0.40. Namely, when two kinds of tablets are packaged in one packaging material, the amt. of dust produced in the packaging material due to vibration during transportation depends on the difference in the frictional coefft. in the package of tablets. Therefore, by specifying the difference in the static frictional coefft. of tablets with the packaging material, friction can be decreased. The two kinds of tablets may be directly packaged in the packaging material or a paper or plastic member may be housed in side the packaging material.
