Title: Removing method for sodium in aluminum or aluminum alloy
Inventor: NARITA KIICHI
IPC: C25C3/24
Filed: 1978-05-22
Abstract: PURPOSE: To remove Na in molten Al by supplying a DC current between the Na- contg. molten Al as an anode and a molten metal, as a cathode, having a m.p. close to that of Al and separated from the anode by a Na ion conductive solid electrolyte partition wall to precipitate the Na on the cathode.  
     CONSTITUTION: Container 1 made of heat resistant material is divided into two chambers by partition wall 3 made of Na ion conductive β-alumina or β"-alumina. One chamber is filled with Na-contg. molten Al 2 as an anode, and the other chamber with molten pure Al or other molten metal 4, as a cathode, having a m.p. close to that of Al. In the chambers are dipped electrode rods 5, 6 made of Mo, W or the like with superior electrical conductivity and corrosion resistance to molten Al. A DC current is supplied between the electrodes, and molten Al 2 is stirred with an inert gas such as Ar or N 2  blown. Na ions in Al 2 pass through wall 3 and precipitates on cathode 6, thus removing the Na.

Title: Reverse copying method
Inventor: ANDOU ITSUROU
IPC: G03G15/06
Filed: 1980-05-12
Abstract: PURPOSE:To obtain a high-quality copied picture with no stain on the surface, by controlling a development bias voltage in accordance with the density of an original picture to be subjected to reverse copying. CONSTITUTION:In general, a electrostatic latent image potential VS is decided by the exposure value when a picture is exposured after uniformly electrify the photosensitive material for electrophotography up to a specified potential level. Here the surface potential VSB of a corresponding electrostatic latent image fluctuate if an original picture having an especially low or high density of background is used. Thus VB-VSB varies outside a range of V1-V2 as long as the development bias voltage VB is fixed, thus causing some stains on the surface of a copied picture. However, if the voltage VB is controlled based on the background density of various original pictures, V1<=VB-VSB<=V2 is always satisfied to obtain the copied picture with no stain on the surface.

Abstract: PURPOSE:To provide a defrosting controller, capable of ensuring the operation thereof, by a method wherein refrigerant gas temperature in overheating zone is detected in the inlet pipeline of an indoor side heat exchanger and refrigerant condensing temperature in two-phase zone of gas and liquid is detected at the center of an indoor side heat exchanger to know a temperature difference therebetween and effect defrosting operation. CONSTITUTION:When room heating operation is started, the timer count of a predetermined time T1 is counted by a micro-computer 9. When the time T1 has elapsed and it is decided, the second timer count of a predetermined time T2 is set. Pipeline temperature (t1) is read by a pipeline temperature detecting element 6 and heat exchanger temperature (t2) is read by a heat exchanger temperature detecting element 6'. A comparator 12 decides whether a difference between the temperatures (t1), (t2) is lower than a set temperature (t). When it is lower, the room heating operation is continued until the time T2 has elapsed. When the pipeline temperature difference (t1)-(t2) becomes higher than the set temperature (t) before the time T2 has elapsed, the second timer count is reset. When the conditions are satisfied, transistors TR1, TR2, TR3, TR4 are operated, a four-way changeover valve 2 is switched, an indoor fan 7 and an outdoor fan 8 are stopped and defrosting may be effected under room cooling cycle.
