Title: Household water softener
Inventor: NAKAZONO SHOJIRO
IPC: C02F5/00
Filed: 1994-02-23
Abstract: PURPOSE:To compactly install a household water softener in a narrow space of a kitchen by making the cross-sectional shape of a cartridge with built-in ion exchange resin long in the water softener provided with plural numbers of the cartridge with built-in ion exchange resin side by side in a main body case. CONSTITUTION:A raw water from water supply side passes through a cartridge 1 for purifying water 1 and is distributed to two cartridges with built-in ion exchange resin via a water passage changeover valve 2. The water passing through the cartridge 10 of one side enters the water passage changeover valve 2 again and is discharged from a discharging pipe 4 and the water passing through the cartridge 10 of the other side also enters the water passage changeover valve 2 and is discharged. In this case, the cartridge 10 of one side works to convert a hard water into the softened water and in the cartridge 10 of the other side, the built-in ion exchange resin is regenerated. And the cross-sectional shape of the cartridge 10 with built-in ion exchange resin is vertically long elliptical and total horizontal dimension is extremely smaller than the conventional one even if two cartridges are arranged side by side.

Abstract: PURPOSE:To enable high-temperature heating and rapid annealing with easy temperature control without contamination with impurities, by forming an oxide superconductor thin film on the base plate which is made of a conductor or dielectric material by heating by the high frequency dielectric heating. CONSTITUTION:A metallic material such as a nickel-based alloy, e.g., stainless steel or hastelloy is used as a base plate and the plate is coated with MgO or BaO. The coated plate is used as a base and heated up to a prescribed temperature by the high-frequency induction heating to form a thin film of an oxide superconductor such as Y-Ba-Cu-O system. The heating is stopped, the base plate is cooled down to give a thin film of superconductor. According to this process, the crystal structure of the superconductive thin film can be prepared and oxygen content in the crystals can be adjusted. Another method can attain the same object by heating the base plate with a radio-frequency heater after formation of superconductor.

Title: Controlling method of dc arc welding machine
Inventor: HAGIWARA SEIGO
IPC: B23K9/00
Filed: 1983-02-17
Abstract: PURPOSE:To decrease spatters without making the periods of a short circuiting and an arc longer and to improve high-speed weldability by making the feed speed of a consumable electrode constant, decreasing the current supply to a welding load gradually for a specified time after generation of the arc and decreasing gradually the increasing speed of the current in the stage of short circuiting. CONSTITUTION:A controlled vairable is decreased gradually to decrease gradually the increasing speed of a short circuiting current at the point of the time when a wire short-circuit with a base metal at the time t1. The current at the point t2 of time when an arc is regenerated is small and therefore the pinching force decreases and the generation of spatters decreases. The arc current is increased for the specified time t2-t3 to provide the period when the base metal is melted after the regeneration of the arc. The arc current is sharply decreased after the time t2-t3 to shorten the arc length for easier short circuiting. The short-circuiting and the arc are repeated in such a way. It is possible to control the number of short circuiting times even if the speed for decreasing the arc current is made higher than in the time t2-t3 after the specified time t3-t4 since the arc is generated.
