Title: Biaxially oriented polyethylene terephthalate film for magnetic disc
Inventor: YOSHII TOSHIYA
IPC: C08J5/18
Filed: 1986-05-12
Abstract: PURPOSE:To obtain a disc with little tracking miss and drop out by a structure wherein the title film consists of polyethylene terephthalate film, the content of COOK terminal group of which is the specified value or less and the refractive index in the direction of the thickness, the index of resistance to surface damage and the coefficient of humidity expansion in arbitrary direction within the plane of which are specified. CONSTITUTION:The content of COOH terminal group of polyethylene terephthalate in filmy state must be 30 equivalent per ton or less. The tracking miss of a magnetic disc made of a base material, the content of COOH terminal group of which must exceed 30 equivalent per ton, increases. The refractive index in the thickness of the film must be 1.492 or less. If said index is larger than 1.492, the number of drop outs tends to increase and also tracking misses increases. Next, the index of resistance to surface damage of the film must be 2% or less. The coefficient of humidity expansion of the film must mentioned above is larger than said range, tracking miss tends to occur during the reproduction of record in a magnetic disc having high recording density and consequently the correct reproduction of signals becomes difficult.

Title: Character pattern write controller
Inventor: TANOSHITA MASARU
IPC: G09G5/24
Filed: 1989-04-26
Abstract: PURPOSE:To shorten a drawing time greatly by storing color data in a shift register by plural pixels and storing color data of the plural pixels in an image memory by single-time access. CONSTITUTION:This write controller is equipped with a color data generating means 3 which generates the color data corresponding to a character pattern, the shift register 10 which is stored with the color data, and a writing means 11. Color data of one pixel which is generated by the color data generating means 3 are stored in the shift register 10 in order and the color data of plural pixels which are stored in the shift register 10 are stored in the image memory 1 by single-time access. The frequency of access to the image memory 1 can, therefore, be decreased and the shift processing of the shift register 10 can be speeded up. Consequently, the drawing time can be shortened.

IPC: H01L29/72
Filed: 1985-05-20
Abstract: PURPOSE:To reduce a pattern size without lowering hPE, by providing a first region of an N<+> type formed on the entire surface of an insular region 25. CONSTITUTION:An insular region 25 is a base, and the surface of the insular region 25 between an emitter region 26 and a collector region 27 operates substantially as the base and is led out by a base electrode 32 using a first region 35 as a base contact. The value rho of the epitaxial layer 22 is set to be the same with a conventional one, and the first region 35 is formed simultaneously in a process of diffusing the emitter region of an NPN transistor formed in another insular region. The first region 35 of an N<+> type is provided on the entire surface of the insular region 25 except for the emitter region 26, the collector region 27 and the region between these regions which operates substantially as the base. This structure enables the curbing of expansion of depletion layers on the surface of the insular region 25, and therefore a distance of separation between the collector region 127 and an isolating region 24 can be shortened by an amount of the curbed expansion. IN addition, the region operating substantially as the base is determined only by the epitaxial layer 22, and therefore the value hFE of a lateral transistor is not lowered.

Abstract: PURPOSE:To prevent a short circuit, etc., at the time of wire bonding to an electrode pad. and to enable response at high speed without generating trouble at the time of assembly by coating the surfaces of regions except a light-receiving section with a dielectric multilayer film having reflectivity close to 100%.

Since the surfaces except the light-receiving section are coated with the film 8, incident light to sections except the light-receiving section can be prevented while no trouble such as a short circuit is generated even at the time of wire bonding to an electrode pad, thus allowing response at high speed. The same effect can be acquired even when a P-type semiconductor substrate is used. That is, the surfaces except the light-receiving section are coated with the film 8 having high reflectivity, thus, obtaining a semiconductor photodetector displaying high-speed response characteristics without generating trouble such as the short circuit at the time of assembly.

Title: Recovery of catalyst for hydroformylation of olefins

Filed: 1977-09-09
Abstract: PURPOSE: To separate for reuse catalyst without causing insolubles to crystallize after distillation of the subject products from reaction products obtained in the synthesis of alcohols from olefins over the Rh-tertiary amine catalyst.  
     CONSTITUTION: An olefinic unsaturated compound (for example, 1-hexene), in the presence of the Rh-tertiary amine catalyst (for example, Rh(CO) 4 Cl 2 . N-methyl- pyrrolindine), is reacted with an oxo gas, consisting of H 2  and CO, charged by the addition of a solvent (for example, polyethylene glycol) of a higher boiling poing than that of the alcohol formed under the conditions of 20 to 300kg/cm 2  and 50 to 200°C. Subsequently, from the reaction products, the subject alcohol (for example, heptyl alcohol) and N-methylphyrrolidine are separated by means of evaporation, and then the residual liquor containing catalyst is further made to perform oxo- reaction by the addition of an olefinic unsaturated compound and a tertiary amine in the same manner as the previous process. Thus, the alcohol can be recovered in high yield as in the previous process.
