Title: Regenerating agent for water softening apparatus
Inventor: MATSUKAWA TAKESHI
IPC: B01J49/00
Filed: 1984-05-30
Abstract: PURPOSE:To regenerate a cation-exchange body in a water softening apparatus into a potassium-type body when the body is regenerated and to obtain potassium ion-contg. soft water by preparing the regenerating agent for the water softening apparatus from a potassium ion-releasing electrolyte such as potassium chloride. CONSTITUTION:The regenerating agent for the water softening apparatus is prepared from a potassium ion-releasing electrolyte such as potassium chloride, potassium sulfate, potassium nitrate, potassium phosphate, potassium carbonate, potassium acetate, and potassium tartrate. When the water softening apparatus is used for a long period, iron rust and scales are deposited on the cation-exchange body in the apparatus, and the iron rust and scales can be removed with a common regenerating agent. However, when a water-soluble oxidizing agent is incorporated into the regenerating agent, the iron rust and scales can be efficiently removed. An alkyl metallic salt of peracid such as potassium percarbonate and a halogen acid salt such as potassium hypochlorite are used as said water- soluble oxidizing agent.

Filed: 1986-05-16
Abstract: PURPOSE:To attain the change of priority in a simple constitution by producing an interruption according to the AND of a corresponding bit between an interruption mask register and an external interruption register. CONSTITUTION:A processor connected onto a common bus together with other processors, input/output devices, etc. contains two 32-bit registers, i.e., an external interruption register EIR121 and an external interruption mask register EIM122 having their corresponding bits serving as two inputs of AND gates 301-332.

Abstract: PURPOSE:To obtain uniform image density by detecting whether transfer paper is present at a transfer position or not, performing switching control so that transfer corona is cut off or weakened when there is no transfer paper, and eliminating the potential difference on the surface of a photosensitive body after transfer operation. CONSTITUTION:An electrostatic latent image formed on the photosensitive body 1 is developed by a developing device 4 and transferred by a transfer charger 6 to transfer paper P fed in from a paper feed base 5.

Title: Saturable reactor
Inventor: ARAI MOTOHIRO
IPC: H01F29/14
Filed: 1986-05-16
Abstract: PURPOSE:To obtain a saturable reactor having a compact and simplified reset circuit, by using a resistor and a capacitor to form a series closed circuit with a reset winding. CONSTITUTION:A series closed circuit composed of a reset winding 1, a resistor 3, and a capacitor 2 is used for a reset circuit in a saturable reactor. When current (i) flows through a forward winding 5 in this saturable reactor, electromotive force is generated in the reset winding 1, so that the capacitor 2 is charged. When the current (i) stops flowing, discharge current from the charged capacitor 2 flows into the series closed circuit in the direction inverse to the charge current, so that the saturable reactor is reset. Realization of such a compact and simplified reset circuit enables a magnetic pulse compression circuit or the like, in which the saturable reactor is used, to be miniaturized.
