Title: Device for pulling up silicon single crystal
Inventor: KOJIMA MASAKATSU
IPC: C30B29/06
Filed: 1987-09-16
Abstract: PURPOSE:To obtain a single crystal by providing a vertically movable specific partition wall fixing jig into a chamber of a pulling up device so that silicon raw materials can be melted in a large volume, the deformation of the partition wall during melting is prevented, and the cost of forming the crucible is reduced. CONSTITUTION:The cylindrical wall 12 which is made of quartz and has a moving route 13 is hung by a partition wall hanging bar 16c to the partition wall fixing jig 16 and is held installed in the upper part in a chamber. The raw materials 5 in the crucible 11 are melted in this state to obtain the melt 4 of the silicon raw materials. The melt 4 is then kept at 1,420 deg.C and the fixing jig 16 is lowered to bring the cylindrical lower part 12b of the partition wall 12 into contact with the crucible 11a; thereafter, the hanging state is released to a detaining hook 12a of the wall 12 and the hook part 16b of the partition wall hanging bar and the fixing jig 16 is rise to the upper part in the chamber. This state is maintained for >=1hr to adhere, fix and integrate the crucible 11 and the partition wall 12, following which a desired phosphorus impurity is doped only in the melt 4b on the inner side of the wall 12.

Title: Manufacture of tervalent vanadium electrolytic solution
Inventor: SUZUKI TAKESHI
IPC: C01G31/00
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To industrially advantageously and easily prepare a vanadium electrolytic solution without installing a special device by adding a reductive catalyst in a quadrivalent vanadium solution and thereafter reducing the quadrivalent vanadium to tervalent vanadium while blowing hydrogen gas into the solution. SOLUTION: Preferably, the reductive catalyst to be used is of a type carrying a metal such as platinum. Whereas the addition quantity of the reductive catalyst to a solution should be an amount capable of reducing the whole quadrivalent vanadium solution to tervalent one, 0.1-3.0 wt.% of the reductive catalyst is desirably added in 3.0-8.0 wt.% of the vanadium solution. After the reductive catalyst is added, the solution is heated to room temperature through 100 deg.C, preferably to 60-95 deg.C. Then, the heated solution is reduced while blowing hydrogen gas into it. The blowing-in is preferably carried out while stirring the solution. The blown-in quantity and blowing-in period of the hydrogen gas are varied depending on reaction capacity, vanadium concentration or reduction temperature and can not specifically be defined.

Abstract: PURPOSE:To provide a panel heater which consumes less electricity and supplies the warm air by generating the gaseous fluid friction heat by means of a multistage rotary heat generator, and transferring the generated thermal energy to a thermal medium. CONSTITUTION:When respective fans 35 are rotated to the direction of arrow (a) by starting respective motors 33, the air in the outer area 32, when a gaseous fluid intake valve 20 is open, is directed from a gaseous fluid intake section 15b via a fan 35 of respective stages to a hot air outlet section 14c to be delivered to the outside from slits 16b. Because respective fans 35 have a gaseous fluid friction heat generating section 36 formed by a gap (g) in their rotating range (R), the heated air is delivered from the slits 16b. The hot air in the hot air outlet section 14c passes through an inlet port 6a to be drawn into a winding pipe 6 where it provides the thermal energy to a thermal medium 7. As the back of the thermal medium 7 is covered with an insulating panel 8, the heated thermal medium 7 radiates the heat from the front surface of a panel 5.

Title: Predicate control system
Inventor: SATO EMI
IPC: G06F9/44
Filed: 1986-09-29
Abstract: PURPOSE:To contrive to improve the predicate processing performance by con trolling intensively the predicate expression knowledges related to the same predicate in a single control unit. CONSTITUTION:The knowledges expressed in predicates are stored in a control unit 14 of an object frame, etc., that is set in response to the predicate equal to that shown in a name expressed in a predicate. Then an object frame control table 13 decides for control a specific predicate to which the control unit set for each predicate corresponds. Therefore the knowledges expressed in plural predicates and having the same predicate are controlled intensively in a single control unit. Thus it is possible to narrow a predicate range where the unification is carried out and therefore to improve the predicate processing performance. Furthermore it is possible to refer to the fragmentary knowledge expressed in a predicate in the form of a group of predicates.
