Title: Device for producing alloy powder
Inventor: ARAKAWA SHIYUNSUKE
IPC: B22F9/10
Filed: 1983-07-19
Abstract: PURPOSE:To provide an inexpensive titled device which produces efficiently and inexpensively alloy powder having a good grain size distribution by the constitution consisting of melting an alloy, ejecting the molten alloy from a nozzle so as to collide against a rotating impeller and to disintegrate the same, bringing the disintegrated alloy into contact with a metallic cooling plate and solidifying quickly the powder. CONSTITUTION:A molten alloy 2 in a crucible 1 is ejected from a nozzle 3 by a gaseous pressure and is brought into collision against an impeller 5 which is driven to rotate by a high frequency motor 4 with a device for producing alloy powder. The ground alloy grains are brought into contact with a metallic cooling plate 6 which is rotated by a roll 10 in proximity to the impeller 5 thereby solidifying quickly the molten alloy. The solidified alloy is stripped by a brush 17 rotated by a motor 7 and the alloy powder is thus obtd. Said impeller 5 is constituted preferably of a bottom plate and 8 sheets of vanes having about 50 deg.-120 deg. angle relative with the rotating direction. The impeller is formed of a metal, ceramics or composite material thereof and the circumferential speed in the position where the molten alloy 2 collides against the impeller is kept at >=5m/sec. A cooling means connected to a cooling water pipe 8 and a drain port 9 is provided to the plate 6.

Filed: 1977-10-31
Abstract: PURPOSE:To obtain the attenuation signal no change in waveform, by providing the detection circuit outputting the output when the voltage of capacitor charging and discharging with the switch is within a given range, and by performing charging or discharging other capacitor through gate switching with this output. CONSTITUTION:When the switch 1 is depressed, transistors TrT1 is turned on, constant current circuit 2 is operated, charging the capacitor C1. When the charging voltage exceeds Va, output is made from the comparator 3, turning on TrT3. When the charging voltage exceeds Vb, the comparator 4 makes output, turning of TrT2. Thus, TrT4, T5 are turned on and the capacitor C2 is charged up with the signal c in a short time. After the completion of charging, the attenuation signal d is outputted at the output terminal 8 through TrT6 and T7. When the modulation signal is fed from the terminal 9 via TrT8 connected to the base of TrT6, the signal e is outputted at the terminal 8. When the switch 1 is detouched, C1 is discharged and the signal c (B) is generated with the comparators 3 and 4, performing charge and discharge of C2.

Abstract: PURPOSE:To improve electric conductivity without spoiling the strength and heat resistance of an Al-Zr-Fe-Si alloy conductor utilizing a heat resisting property of precipitated Zr by combining a heat treatment and drawing to manufacture said conductor. CONSTITUTION:An Al alloy consisting, by weight, of 0.1-0.8% Zr, 0.05-0.8% Fe, 0.04-0.5% Si and the balance Al is subjected to forging and hot rolling by continuous or semi-continuous casting and rolling to form a roughly drawn wire in which Zr is subjected to solid heat treatment. The wire is heated for 10- 150hr at 300-450 deg.C to precipitate the Zr contained therein and is then subjected to cold drawing at <=50% reduction rate of area. The wire is further subjected to a heating treatment for 5-70hr at 350-450 deg.C to precipitate uniformly and finely Zr, then to cold drawing at <=50% reduction rate of area. The alloy conductor which has the electric conductivity equal to that of the conductor utilizing the heat resisting property of the precipitated Zr and exhibits much higher strength and heat resistance is thus obtd.

IPC: G03B3/06
Filed: 1995-05-30
Abstract: PURPOSE: To appropriately set the resolving power of focusing error compensation and the compensation range complying with applications. CONSTITUTION: A detected light beam from a point on an original arranged on a reference plane R is made to be parallel by a first lens L11, transmitted through a half mirror 2 and once converged by a second lens L12.
