Inventor: NONAKA YASUHIRO
IPC: C23C14/24
Filed: 1989-12-28
Abstract: PURPOSE:To avoid troubles at the time of melting, such as bumping, adhesion of metal, and hanging and to obtain an alloy minimal in contamination with oxygen and free from the remaining of shrinkage cavity by previously subjecting Ti as raw material to degassing treatment at the time of refining the alloy by using a calcia crucible. CONSTITUTION:A raw material consisting of, by atom, 48-70% Ti and 30-52% Al is melted in a calcia crucible and a TiAl-base intermetallic compound is refined. At this time, after hydrogen gas in Ti is sufficiently released by previously applying heating to Ti as raw material at about 700-1000 deg.C in a degree of vacuum higher than 10<-1>mmHg for several hours in the calcia crucible, the above Ti is melted together with Al as raw material in vacuum or in an Ar atmosphere.

Title: Lead-acid battery positive electrode plate
Inventor: MAEDA KAORU
IPC: H01M4/62
Filed: 1991-12-20
Abstract: PURPOSE:To improve the usage of active material and the life characteristics of a battery by providing carbon black with a liquid absorption of a specified value or less as determined by a di-n-butyl phthalate oil absorption, and generating tetrabasic sulphate in a positive electrode active material. CONSTITUTION:Lead powders prepared by the ball mill method is mixed with water and kneaded before being mixed with dilute sulfuric acid water and further kneaded. A specified amount of carbon black with a DBP oil absorption of 350ml/100g or more and then water is subsequently mixed with the paste so that it becomes as hard as its former state before the addition of carbon black. After being filled in a grid body comprising a lead-antimony series alloy, the paste is matured and dried in an atmosphere with a temperature of 80 deg.C and an RH of 95% to generate tetrabasic sulphate in a positive electrode active material. Thus, the presence of the carbon black with a liquid absorption of 350ml/100g or more improves formation efficiency and active material usage efficiency. In addition, the tetrabasic sulphate generated in the positive electrode active material improves the life characteristics.

Abstract: PURPOSE: To strongly fasten nuts for strongly temporary-locking building members and preventing their together rotation by forming irregularities to engage with both the outside of a rod-shaped member and the cavity inside a cylindrical washer in the direction of rotation centering around the axial center of the rod-shaped member. CONSTITUTION: In a temporary locking bolt 21, a rod-shaped member 18 is inserted into the overlapped holes 26, 27 of building members 24, 25 to be temporarily fixed to make a through hole 14 protrusive to an opposite side, and then a cylindrical washer 29 is rotated to turn an opening 13 having a small bore downward. A pin 19 charged in the through hole 14 therefore slipps down under empty weight, and its thin tip 20 protrudes downward out of the through hole 14. When a nut 17 is locked, the peripheries of the holes 26, 27 contract between the cylindrical washer 29 and the pin 19, and the building members 24, 25 are thereby mutually temporarily fixed.  In this case, irregularities 32, 35 to engage with both the outside of the rod-shaped member 18 and the cavity inside of the cylindrical washer 29 in the direction of rotation centering around the axial center 11 of the rod-shaped member 18 are formed.

The outgoing light is coverted from an s-polarized light into a p-polarized light and the luminous flux made incident on the splitter 7 again as the p-polarized light passes through it as it is to headed to an objective lens for high-density disk 3. A luminous flux emitted from a laser module for conventional disk 2 is made incident on the spilitter 7 as an s-polarized light and the advancing direction of it is changed to be guided to an objective lens for conventional disk 4.  Thus, a recording and/or a reproduction can be performed with respect to disks of one kind or more whose corresponding wavelengths and thicknesses are different.

Title: Fully double control system
Inventor: KAWANABE HIROYUKI
IPC: G06F15/00
Filed: 1990-11-30
Abstract: PURPOSE:To improve the development value, the reliability, the processing performance, and the maintain ability of a business program by using a queue when the business program is written and transferring the data to the partner business program via a circuit. CONSTITUTION:When a business program 1 is opened, an on-line monitor 2 registers a queue unique number, an output queue 5, an input queue 6 and a logical ID into a queue control table 3. Then the monitor 2 queues the data into the queue 5 of a unique number in response to the write/read state of the program 1 and transmits the data to the circuit together with the logical ID. Meanwhile the data having a logical ID which are received via the circuit are queued into the queue 6 of a unique number and then transferred to the program 1. Thus it is not required for the program 1 to be directly conscious of an address to a business program of the partner side of communication. As a result, the number of business programs and the number of production steps of business programs can be decreased together with improvement of the development value, the reliability, the processing performance, and the maintainability of the business programs.

IPC: H01C10/32
Filed: 1992-12-21
Abstract: PURPOSE:To provide a sensitivity adjuster of a photoelectric sensor that does not damage a series of speed change gears even if a speed change gear connected to a rotary section of a single rotation-type variable resistor is rotated.

When a rough adjustment is made, the speed change gear 14 which is rotated in linkage with the rotary section of the single rotation-type variable resistor 11 is rotated independently of the speed change gear 13. Therefore, even if the speed change gear 14 connected to the rotary section of the single rotation- type variable resistor 11 is rotated, a series of the speed change gears 13 and 14 are not damaged.

Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent impurities interfering the polymerization of distilled monomers or low-boiling dissociation products contaminating distillates by continuously distilling a thermolabile monomer under a reduced pressure in a column according to a specific method. SOLUTION: When (A) a thermolabile monomer is continuously distilled under a reduced pressure in a column, the component A in the form of a vapor or a liquid is initially fed to the column and (B) an inert distillation aid forming a heteroazeotrope with the component A is introduced into an evaporator at the bottom but separately from the monomer feed and evaporated in the evaporator. Otherwise, an emulsion comprising the components A and B is fed into the evaporator or the column. The azeotrope is then condensed at the top of the column and the resultant mixture is separated in a phase separator to remove the component A. The component B is returned to the column or, as desired, worked up thereafter. The component having a higher boiling point than that of the component A is removed from the bottom of the column.
