Title: Vacuum space generating device
Inventor: ARAI YASUO
IPC: B22D11/06
Filed: 1979-11-07
Abstract: PURPOSE: To improve surface roughness of metal ribbons, by maintaining only a space in which molten metal is solidified quickly under vacuum state at quenched metal ribbon manufacturing device.  
     CONSTITUTION: Molten metal is supplied from nozzle 2 to cooling body 1 which is rotating in arrow direction 4. Nozzle 2 can be fitted to supporting board 3 with packing materials 5. An removing box 6 of cooling body surface and blown gas reservior box 7 are installed before and after the molten metal supplying section on cooling body 1, respectively, and they are fixed to the supporting board. Their both sides are interrupted with side boards 8. Vacuum pump 9 sucks air through (a) and (b) from air removing box 6 and interrupts vacuum space 11 from the outside. A high pressure gas is flowed to gas reservoir box 7 through (c) and (d) by blower 10, and thus adhering property of ribbons is improved. Hole 12 is used to blow a specified gas, if necessary. By this process, only the space where molten metal touches cooling body 1 and is solidified, is maintained under vacuum condition and adhesion between molten metal and cooling body 1 is increased, and thus surface roughness of metal ribbons is improved.

Abstract: PURPOSE:To restrict noise generated by parasitic capacity without making surge breakdown prevention ineffective by a method wherein a surge protection resistant circuit is provided in one or both of the intervals between an input terminal and a power supply terminal and between the input terminal and a grounding terminal through the intermediary of series resistors. CONSTITUTION:Diodes D1, D2 are provided in the intervals between an input terminal 3 and a power supply terminal 4 as well as between the input terminal 3 and a grounding terminal 5 through the intermediary of series resistors R1, R2.

IPC: H02J7/04
Filed: 1988-06-13
Abstract: PURPOSE:To prevent an overcharge by providing a timer circuit, and switching a trickle charging upon lapse of a predetermined period of time from the start of charging. CONSTITUTION:A timer IC 9 starts counting simultaneously upon start of charging, and the output of the IC 9, i.e., the output of a timer circuit 6 is varied from an OPEN state to 0V when a predetermined period of time determined by a time constant set by a resistor 10 and a capacitor 11 is elapsed. The IC 9 is so constructed that the output thereof ramains as it is if it is once varied to 0V. If the output of the timer 6 becomes 0V, the output of the N-P-N transistor 8 of a switching circuit 5 is turned OFF preferentially to the detected output of a voltage detector 4, and a charging circuit 3 is shifted to a trickle charging.

Filed: 1978-11-20
Abstract: PURPOSE: To make uniform the quality of spot welding by keeping constant the voltage and current, by combining the open loop control system and closed loop control system.  
     CONSTITUTION: The operation time t 1 -t 0  of time limit circuit 2 and reference voltage waveform of sawtooth shape are adjusted so that the intersection of output voltage of supply voltage detecting circuit 1 and sawtooth reference voltage E be θ when supply voltage is v, θ 1  when v 1 , and θ 2  when v 2 . In this adjustment, when the supply voltage decreases to v 1 , the conducting angle of a thyristor 8 increases to θ 1 , and the effective voltage applied to the primary side of a transformer 10 is always controlled at a constant value. In the compensation for making the welding currenc constant, the current is detected by a welding current detector 11, and the size of time limit t 1 -t 0  of the time limit circuit 2 is limited by the size of this detected current, and when the welding current decreases, the conducting angle of the thyristor 8 increases. The intersection of the output voltage of sawtooth wave generating circuit 3 and the output voltage of supply voltage detecting circuit 1 occurs in the direction to decrease the conducting angle of the thyristor 8. Therefore, the welding current is controlled always at a constant value.

Inventor: SUZUKI YASUO
IPC: G03G15/09
Filed: 1984-07-12
Abstract: PURPOSE:To improve the wear resistance and durability of the surface of a developer carrier and to obtain a sharp image by forming an Ni-Al alloy layer 1 on the surface of the developer carrier. CONSTITUTION:The Ni-Al alloy layer 1a is formed on the surface of the sleeve 1 by plasma thermal spraying. In this case, Ni-2-7wt% Al alloy containing 2-7wt% aluminum based on the total weight causes exothermic reaction named as thermit reaction, so the adhesive strength among Ni-Al alloy particles and adhesion to the sleeve surface increase, so that a high-hardness thermally sprayed layer is formed. Further, the Ni-Al alloy has low porosity and is hard to separate from the sleeve surface and tolerant to wear. Further, the sleeve surface is normally roughened for the triboelectric charge donation due to abrasion against toner, improvement of toner conveyance, prevention against the fusion of toner on the sleeve, etc., but the discharge amount of powder during the plasma thermal spraying and a current value are increased to reduce the surface roughness, thereby giving desired roughness to the sleeve surface without any roughening work.
