Abstract: PURPOSE:To form pulverous spherical particles having excellent quality by generating an arc between Ti metallic electrodes and injecting molten liquid drops onto a water-cooled copper collision member under high-speed rotation in the stage of grinding a Ti metal having strong activity. CONSTITUTION:Wires 6, 6 of metal such as Ti or Ti alloy having large activity are un-wound from reels 10, 11 and are disposed by guides 8, 9 to face each other in a cylindrical granulation chamber 1. The arc is generated by the voltage impressed to the wires from a DC power source 14, by which the wires are melted. The molten metal is injected in the form of the liquid drops 28 of the molten metal by the pressurized gaseous Ar blown from an injection pipe 17 provided in the upper part toward the water-cooled copper collision member 2 under rotation at several hundreds rpm. The powder 29 cooled and spheroidized by the collision is bombarded against a protective plate 26 by centrifugal force so as to deposit to the lower part of a granulation chamber 1. The powder is then taken out of a rotary valve 27. The gaseous Ar flows through an outlet 18 and a dust removing and pressurizing device 24 and is again cyclically used to the Ar injection pipe 17.

Title: Vehicel air conditioner
Inventor: SAKA KOICHI
IPC: B60H1/00
Filed: 1992-07-15
Abstract: PURPOSE:To provide a vehicle air conditioner by which a comfortable air conditioning feeling can be given to an occupant when only one occupant is seated in a vehicle room and an air conditioning load of a heat exchanging means such as an evaporator can be reduced to the possible minimum level. CONSTITUTION:When only a driver is seated and a mode is set in an inside air circulating mode as well as in a cooling mode, a blowoff mode on the front passenger seat side is set in a foot mode, and opening of a front passenger seat side air mix damper 15b is set at 0%. Thereby, since a cooling wind blown off from a blowoff port 11b under a front passenger seat is sucked in immediately from an inside air introducing port 25 opening at the foot of the front passenger seat, temperature in an air upstream part of an evaporator 23 can be lowered. Thereby, since a cooling load of the evaporator 23 can be reduced, motive power consumption of a compressor 27 can be reduced.

Title: Capstan driver of magnetic sound recording and reproducing device
Inventor: BAN ITSUKI
IPC: G11B15/28
Filed: 1982-10-28
Abstract: PURPOSE:To assure reproduced sounds of high quality with its wow and flutter reduced down to <=0.1%, by providing a capstan which is inserted and held so as to have a rub with the 1st and 2nd slide bearing members which contain two projected parts and an opening part, a rotary shaft having the 1st rotary wheel of a large diameter fixed the lower end of the rotary wheel and a flay motor which is fixed to the lower surface of a deck respectively. CONSTITUTION:A capstan 4 has two projected parts 9a and 9b of a slide bearing member 9 at its right side along with an opening part provided at the left side respectively. When a pressure is applied to the capstan 4 from the left side as shown by an arrow A, the capstan 4 is pressed to the member 9 via some thickness of an oil film and turned. Thus the deflection and vibration are minimized to eliminate the defect of an existing bearing containing oil. A motor 12 has a flat structure and therefore uses a type having a gap in the axial direction, and either a semiconductor type or a commutator type is available. A flat plate type armature 13 is fixed to a rotary shaft 14, and a columnar commutator 13a is fixed at the lower end of the armature 13. The accuracy of diameters of rotary wheels 11 and 17 affects the wow and flutter. Thus the accuracy of correspondence between the capstan 4 and the shaft 14 must have about 10<-4> ratio between the diameter R and its deviation DELTAR in order to secure 0.03% wow and flutter.

Inventor: INASAWA YOSHIO
IPC: H01Q21/06
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To reduce a time for calculation and to find desired directivity by including a step for expressing plural binary variables corresponding to the thinning state of an element by one multivalue variable in the gene expression of a genetic algorithm. SOLUTION: In order to find the adaptive value of some individual, it is necessary to find the directivity of an array antenna corresponding to thee individual. This method does not binary-display a gene having a value of 0 to 2k-1 once to investigate the thinning state of each element to add the contribution of not-thinned elements but previously calculates contribution directly corresponding to the value of 0 to 2k-1. For example, a complex electric field which is generated at an observing point (x) by an I-numbered element is set to be Ei (x) to find contribution at an observing point (x) by a gene '5' on the right end of an individual (Ci) having genetic information of '10 2 6...5'. In order to obtain it from Ei (x), '5' is binary-displayed to be '0101' to find numbers corresponding to an element (1) and an element (3).

Title: Stacking device
Inventor: KURAMOCHI TOSHIRO
IPC: B65G57/24
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To smoothly stack member without the member being decayed by resilience even if a box in a state in which a center is expanded is pushed out by arranging a sheet for covering a top face of a stepped load member fed out to a third carrying unit and mounting both ends thereof to an extruding unit. SOLUTION: When a first stacking member 1' is loaded on a third carrying unit 4, a sensor 8 detects it, and the stacking member 1' is sequentially pushed out by a cylinder 6. Since a sheet 13 pressurizes the top face of the stepped load member 1' by a predetermined pressure, even a box shaped member whose center is expanded is never decayed. When the stacking member 1' is loaded on the third carrying unit 4 in predetermined quantity, a pressure plate 11 of an extruding unit 10 presses and holds the top face of the stacking member 1' by means of a cylinder 12 in which state the plate is extruded horizontally and housed in an integrating box 18. Then, the pressure plate 11 returns to its original position. This operation is returned, and the stacking member 1' is integrated in the integrating box 18.

Title: Memory device
Inventor: HORIGUCHI TATEJI
IPC: G09G5/00
Filed: 1989-07-21
Abstract: PURPOSE:To set a word boundary at an optional bit position by using an address which is so far supplied in common to all memory elements and an address obtained by applying the increment to the former address and giving these addresses to a pair of memory elements set on the boundary on words. CONSTITUTION:In an example shown in the diagram, only an address A10 is equal to 0 owing to dAD = 10. As a result, an address AD is inputted to a memory element connected with D10 - D15 of a data bus 12. At the same time, an address AD + 1 stored in a register 5 is inputted to a memory element connected with D0 - D9 of the data bus. The write data DA is shifted to the right by only dAD equal to 10 bits by a data rotator 4. As a result, the 16-bit data DATA of the bus 12 are written to a 16-bit area covering the 11th bit of an address AD through the 10th bit of an address AD + 1. Thus the data are written into a memory as if a word boundary exists between the 10th and 11th bits of the bus 12.
