Title: Granulated agent for adsorption
Inventor: NIIHORI KEISUKE
IPC: B01J2/28
Filed: 1978-12-27
Abstract: PURPOSE: To provide a granulated agent for adsorption consisting of alkali earth metal aluminate gel, magnesia cement and an additive and capable of improving the adsorption performance.  
     CONSTITUTION: Magnesia cement and an additive are added to alkali earth metal aluminate gel, mixed with water, kneaded, dried, and granulated. The cement and the additive are added in an amt. of 2W50wt% and 0.5W10wt%, respectively to the amt. of the granules. The additive includes fine crystals of cellulose such as carboxymethylcellulose and lignosulfonate in pulp waste liquor or the like. The diameter of the granules is most pref. about 0.5W0.8mm. A diameter more than 0.8mm remarkably deteriorates the adsorption performance of the granules, and a diameter less than 0.5mm brings about undesirable results with respect to mechanical strength, press. loss in a tower, etc.

Abstract: PURPOSE:To permit the outputting of a frosting confirmation signal and a defrosting confirmation signal with a correct timing by a method wherein one set of air capacitor is employed to discriminate the confirmation of frosting from the confirmation of defrosting utilizing different phenomena generated in the air capacitor. CONSTITUTION:When the adhering amount of frost 41 to the surface of a refrigerant circulation pipe 17 is increased, the electrostatic capacity of an air capacitor 27 is increased and the oscillating frequency of an oscillating circuit 29 is reduced. A judging circuit 30 responds oscillating frequency at that time and rises up outputting signals P1, P2 while outputting a frosting confirmation signal. Then, precooling is effected for a given period of time T1 and a compressor 1 as well as fan are stopped while conductions of a glass tube heater 15 and a vacuum heater 16 are started. When the melting of the frost 41 is advanced, a pool 42 contacts with an electrode plate 22 to short-circuit the refrigerant circulation pipe 17 and the electrode plate 22 electrically and the oscillating operation of an oscillating circuit 29 is stopped. As a result, outputting signals P1, P2 rise up and a defrosting confirmation signal is outputted.

Title: Production of liquid developer
Inventor: NOURA SHIYUUTA
IPC: G03G9/12
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid developer providing a stable characteristic from just after production, without any dispersion in grain diameters and electric characteristics due to the standing period of the liquid developer or between production lots by applying processing with heating to a toner composition after wet dispersion. SOLUTION: The production consists of the processes of melt-kneading and roughly pulverizing a toner raw material including at least binding resin and a colorant and wetly dispersing the toner raw material into a liquid having an insulating property. The toner composition after the wet dispersion is processed by heating at 40 deg.C<=60 deg.C preferably, for three or more hours, to produce the liquid developer. This developer is suitably used as a full color developer in particular. In other words, the execution of processing by heating has a special effect on the toner composition after the wet dispersion into the liquid having the insulating property. Then, a heating time for the toner composition is more preferably five or more hours. When this heating time is too short, the prevention of the dispersion between the lots is hardly made effective.

Title: Manufacture of superconducting magnet and superconducting magnet
Inventor: IGA ATSUSHI
IPC: H01F6/06
Filed: 1988-06-29
Abstract: PURPOSE:To facilitate manufacture and handling, and to simplify usage by forming a tubular superconductor and successively generating transition from normal conduction to superconduction from one end of the superconductor in a ferromagnetic field. CONSTITUTION:A samarium-cobalt magnet 13 and a zirconia bar 12 are brought into contact under the state of normal conduction. Magnetic flux emitted from the magnet 13 passes in the zirconia bar 12 and a tubular normal conductor 11' in the periphery of the zirconia bar 12 without being constrained, and magnetic flux 15 returns to magnetic flux 14. When the whole is cooled from the magnet 13 side while a superconductive region is increased gradually, magnetic flux 15 is constrained slowly, lastly restricted from the whole tubular superconductor 11, and confined into the tubular superconductor 11. When the magnet 13 and the zirconia bar 12 with the tubular superconductor 11 are separated under the state, magnetic flux restrained by the tubular superconductor 11 is confined in the tubular superconductor 11 as it is, thus forming a superconducting magnet.
