Abstract: PROBLEM TO BE SOLVED: To improve the writing property, the erasing property and the antiglare property without requiring a treatment of the surface layer by laminating a white backing material layer on one surface of a fluorine resin film containing ETFE and a propylene-TFE based copolymer or a vinylidene fluoride- hexafluoropropylene based copolymer.

Title: Purification of tocopherol
Inventor: ISHII KIETSU
IPC: C07D311/72
Filed: 1983-05-19
Abstract: PURPOSE:To purify tocopherol in high purity, by dissolving a composition containing tocopherol in a solvent, and passing the solution through a non-polar polymeric adsorbent resin, thereby selectively adsorbing the pigments existing as impurities. CONSTITUTION:A tocopherol-containing composition is dissolved in a solvent (e.g. ethanol), and the solution is passed through a non-polar polymeric adsorbent resin (e.g. Duolite S-861) to effect the selective adsorption of the pigments existing in the composition as impurities and obtain purified tocopherol. The decolored tocopherol obtained as the unabsorbed fraction can be delivered as the final product only by distilling out the solvent. The product has higher color stability than the product obtained by conventional process, and the process for the removal of the adsorbent is unnecessary in the above process. The pigments can be removed without troubles even if the polar solvent contains an acid, and accordingly, the discoloration by the desorption of non-alpha-tocopherol fraction with an acid in a basic anion exchange resin, etc. can be carried out successively to the above purification process.

Title: Manufacture of semiconductor device
Inventor: IKEGAMI MASAMI
IPC: H01L21/316
Filed: 1988-04-12
Abstract: PURPOSE:To form a highly reliable oxide film of high quality on a diffusion layer, by forming the diffusion layer on a part of a semiconductor substrate with ion implantation and making an epitaxial layer grow on the above diffusion layer and then, by diffusing upwards the diffusion layer in the above epitaxial layer, thereby forming the oxide film on the surface of the epitaxial layer. CONSTITUTION:After forming an oxide film 12 for protection on the surface of a P-type silicon substrate 11, a resist pattern 13 is formed on the oxide film. An N-type diffusion layer 14 is formed on the part of the substrate by implanting As<+> ions into the substrate by using the resist pattern as a mask. Then, after removing the resist pattern and the oxide film for protection, a P-type epitaxial layer 15 is formed on the surface of the exposed substrate. In such a case, the N-type diffusion layer diffuses upwards up to the surface of the epitaxial layer. After the field oxide film 16 is formed by oxidizing the epitaxial layer selectively, a gate oxide film 17 is formed by thermal oxidation on the surface of the epitaxial layer comprising the N-type diffusion layer. In this way, the damage on the substrate is relieved by the thermal treatment in the case of the epitaxial growth and it eventually results in the decrease in defective crystals. As the defective crystals on the surface of the epitaxial layer are limited in number, reliable oxide films of high quality which are low in deterioration grow even on the diffusion layer.

Abstract: PURPOSE:To produce an amorphous soft magnetic material having excellent magnetic permeability in a wide frequency range by subjecting the amorphous soft magnetic material to two times of heat treatments in a static magnetic field under specific temp. conditions. CONSTITUTION:A sample 1 formed with an amorphous alloy film by a sputtering method, etc., on an alumina substrate is put into a vacuum heating furnace 3 and a yoke 5 mounted with a magnet 6 is freely rotatably disposed to the outside of the furnace. The magnetic field in the direction approximately orthogonal with the direction where the high high-frequency magnetic permeability is desired to be finally obtd. is then impressed by the magnet 6 to the sample 1 and the sample is heated in this static magnetic field by a heater 4 at the temp. lower than the crystallization temp. and curie temp. of this amorphous alloy. The yoke 5 is thereafter rotated by a pulse motor 8 to impress the static magnetic field in the direction where the high-frequency magnetic permeability is desired to be finally obtd. to the sample 1. The sample is then subjected to the heating treatment at the 1st heat treatment temp. or the temp. lower than said temp. The magnitude of the uniaxial magnetic anisotropy of the amorphous soft magnetic material is controlled by the temp. and time of the 2nd heat treatment. The amorphous soft magnetic material having the high magnetic permeability in the frequency range is thus produced.
