Title: Production of optically active pantolactone
Inventor: TAKEDA SHIGEO
IPC: C07B57/00
Filed: 1989-03-15
Abstract: PURPOSE:To easily obtain the subject compound useful as a raw material for calcium pantothenate in high optical purity with simple operation by carrying out optical resolution of DL-pantolactone with a specific optical resolution agent. CONSTITUTION:The objective compound is produced by the optical resolution of DL-pantolactone using optically active 2-benzylamino-1-phenylethanol as an optical resolution agent. The amount of the optical resolution agent is usually equimolar to DL-pantolactone used as a raw material, however, it can be decreased to about 0.5mol. The optical resolution agent may be used in isolated state when the raw material has the form of pantolactone or free pantoic acid. When the raw material is an alkali metal salt of pantoic acid, the optical resolution agent is used in the form of a mineral acid salt. The above resolution agent can be produced by carrying out asymmetric hydrogenation of N- benzylphenacylamine hydrochloride and recrystallizing the isolated product.

IPC: A61B6/02
Filed: 1978-05-22
Abstract: PURPOSE: To obtain a tomographic image with no error by positioning the member of a checked body to be observed at the center of a fault plane by correcting, by providing a correcting member, made of a material with X-ray absorptivity close to the mean absorptivity of this checked body, to the surface of this body.  
     CONSTITUTION: Inside of trestle 3 with hole 3a for inserting checked body 5, rotatable X-ray tube 1 and X-ray detector 2 are arranged with hole 3a between. After the CT device is constituted in this way, bed-ceiling drive table 4 with mounted body 5 is inserted into hole 3a and the body is irradiated with electron beams from X-ray tube 1, so that detector 2 will obtain X-ray absorption data from every direction of the fault plane. At this time, the part to be observed tends to deviate from the center of checked body 21 to position C as shown in the figure, which causes the error of absorption data. For the purpose, correcting member 31 made with wax with absorptivity close to the mean X-ray absorptivity of checked body 21 is arranged on the surface of checked body 21 with position C agreeing with the center of the fault plane, so that X-ray energy will be equalized in any direction.

Filed: 1990-03-12
Abstract: PURPOSE: To avoid a collision between a disk and a pickup by returning an objective lens to a first position and thereafter again driving the objective lens to a second position with inclined signals when the objective lens reaches the second position without the generation of control signals. CONSTITUTION: A inclined signal generating means 278 generating inclined signals gradually varying in level from a first level corresponding to the first position (position most away from the disk) to a second level corresponding to the second position (position nearest to the disk) in the optical axis direction of the objective lens and a focus achieving logic circuit 272 are provided with, the inclined signals are fed to the objective lens driving means to drive the objective lens to the second position in accordance with focus unachievable signals. Hear, when the objective lens position reaches the second position without the generation of control signals by the focus achieving logic dircuit 272, the objective lens position is returned to the first position, thereafter the objective lens is again driven toward the second position from the first position with inclined signals.  Since the pull in operation of the focus is retried like this, the collision between the disk and the pickup is avoided.

Title: Bump forming body and forming method of bump
Inventor: MITANI TSUTOMU
IPC: H01L21/321
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To reduce electric resistance, mostly prevent generation of gas after mounting, and improve reliability, by constituting a bump of at least one layer of a metal sprayed thick film. SOLUTION: A base layer 5a constituted of an aluminum sprayed thick film is formed on a pad electrode 2, in the state that the peripheral part of a passivation film 3 is covered. A surface layer 5b constituted of a copper sprayed thick film is formed on the base layer 5b, and a bump 6 of two-layered structure is formed. Since the purity of the bump 6 constituted of the metal sprayed thick film is high, electric resistance of the bump itself is small, and gas is hardly generated from the bump after mounting, so that reliability is improved. As a result, a bump forming body excellent in electric characteristics and connection reliability wherein an interlayer insulating film, an active layer, multilayered wiring can be arranged can be obtained.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject colorless transparent compound without change with time, as necessary by one single distillation, by adding an additive forming a complex with phosphorus trichloride to a reaction solution of an aliphatic carboxylic acid with phosphorus trichloride when the reaction solution is distilled. SOLUTION: When a reaction solution of an aliphatic carboxylic acid (e.g. methacrylic acid) with phosphorus trichloride is distilled, an additive (e.g. N,N- dimethylformamide) forming a complex with phosphorus trichloride is added to the reaction solution, and then, distillation of the reaction solution is carried out. A method for dropping phosphorus trichloride to an aliphatic carboxylic acid is preferable as the method for reacting the aliphatic carboxylic acid with phosphorus trichloride. The reaction is preferably carried out in the presence of a quinone as a polymerization inhibitor at 50-60 deg.C reaction time for 0.5-3 hr dropping time. It is preferable to distill an acid chloride after finishing dropping and then aging the solution for 1/4 to 2 hr.  It is preferable to start evacuation of the interior from 200 mmHg pressure, and finally distill the acid chloride at 30 mmHg pressure.
