Title: Apparatus for manufacturing gold particle
Inventor: KUTSUKAKE TOKUJI
IPC: B22D25/02
Filed: 1982-06-09
Abstract: PURPOSE:To obtain the gold particle-manufacturing apparatus which can manufacture approximately spherical gold particles made even in the distribution of particle size, in pouring gold melt into a gold-ejecting crucible, by adopting the constitution that its pouring amount can be controlled by a rotary means whose rotation speed is made variable. CONSTITUTION:Gold melted in a crucilbe 2 by a high-frequency coil 3 is poured into a gold-ejecting crucible 17 kept hot with an electric oven 16 by the operation of a rotary means 8. The gold melt poured into the crucible 17 is then ejected through a nozzle 18 into a tank 14 reserving water in it. The condition of spraying gold through the nozzle 18 into the tank 14 is made uniform by controlling the gear ratio of the gear box 12 of a means 8 to change the rotation speeds of a rotary vessel 5 and the crucible 2. Thereafter, gold ejected from the crucible 17 is made into a whirlpool by water previously ejected through the water-spray nozzle 27 of a hydraulic rotary means 25 and then dropped into the stream of water in the tank 14 being rotated. Thus, all of the gold particles solidified into an approximately spherical shape are let pass through the tapered part 19 of a hopper 19 and recovered in a recovering vessel 20.

IPC: H01M4/57
Filed: 1982-06-07
Abstract: PURPOSE:To suppress formation of an irreversible PbSO4 layer and improve the standing performance after overdischarge by constructing a positive plate with more than one positive active mass layers having different filling densities. CONSTITUTION:A positive plate 10 is constructed with more than one positive active mass layers 11 and 12 having different filling densities, and the filling density of the active layer 11 located in the vicinity of a current collector makes higher than that of the active mass layer 12. Pore volumes and pore diameters in the vicinity of the current collector 13 are reduced. As a result, fine pores are blocked and penetration of electrolyte is suppressed, and diffusion of electrolyte to the vicinity of the current collector is suppressed. When the diffusion of electrolyte to the vicinity of the current collector is prevented, the formation of PbSO4 layer (this layer becomes inactive while a battery is allowing to stand, that is, irreversible PbSO4 is formed) caused by reaction of PbO2 layer on the surface of the current collector with SO4<--> ion in the electrolyte is suppressed. Therefore, the standing performance after overdischarge is improved.

Filed: 1993-04-26
Abstract: PURPOSE:To simplify the pull in with a simple constitution by controlling a voltage control oscillator by a signal obtained by adding a hourly voltage varying offset voltage to the output signal of a loop filter at the time of the step-out of a phase locked loop circuit. CONSTITUTION:A phase locked loop circuit is formed of a path constituted of a voltage control oscillator 1, first frequency-dividing circuit 3, phase comparator 6, and loop filter 7. When the phase step-out is generated at the circuit, the phase comparator 6 detects it, and an offset voltage generating part 8 generates the offset voltage which is hourly and successively changed. This voltage is added to the output signal of the filter 7 by an adding circuit 9, and supplied to an oscillator 1. The output frequency of the oscillator 1 is swept by the offset voltage. Thus, even when the synchronous step-out is generated at an automatic frequency control circuit using the phase locked loop circuit, the pull-in can be operated in the simple constitution, and reliability can be improved.

IPC: G03G9/08
Filed: 1991-04-30
Abstract: PURPOSE:To enhance void resistance without deteriorating fixation and blocking resistance by using a fluorine based surface active agent (perfluoroalkylpolyether) in a binder resin as a reducing agent of surface tension. CONSTITUTION:In a toner for electrophotography using the binder resin, the fluorine based surface active agent expressed by the formula I is used as the reducing agent of the surface tension in the binder resin. In the formula I, R1 is H or F, R2 is H or F and R3 is H or alkyl group. That is, to prevent deterioration of fixation attendant upon increasing m.p. of the binder resin or to prevent deterioration of blocking resistance attendant upon decreasing glass transition point of the binder resin, even when using the binder resin relatively lower in melting viscosity, generation of void due to coagulation is prevented by using at least the reducing agent of surface tension, which decreases surface tension or intermolecular force working among molecules composing of the binder resin.
