Title: Hot-water supplying system for internal-combustion engine
Inventor: JINBO KENSAKU
IPC: F01P3/20
Filed: 1981-09-01
Abstract: PURPOSE:To reduce the amount of remaining hot-water in the internal-combustion engine and prevent dripping of the same water onto a floor or the like by a method wherein hot-water in a vacuum tank is returned to a head tank when a predetermined test operation for the internal-combustion engine to be tested is  finished. CONSTITUTION:The hot-water, remained in said internal-combustion engine 3 in case the predetermined test for the internal-combustion engine 3 to be tested is finished and the engine is separated from the hot-water head tank 1, is sucked into the vacuum tank 7 through a discharging valve 13 and an one-way returning pipe 6, thereafter, is returned to the cooling water head tank 1 by a returning pump 9. According to this method, the remained hot water will never drip onto the floor surface at the outside thereof and the amount of the hot-water remaining in the internal-combustion engine may be reduced remarkably.

Title: Ion source
Inventor: HIKAWA KAZUNORI
IPC: H01J37/08
Filed: 1993-06-10
Abstract: PURPOSE:To prolong the lifetime of an ion source, and to stabilize the ion beam for a long time by insulating a part near an ion lead-out port of a plasma chamber from other parts, and providing a slit applying means (potential difference generating means). CONSTITUTION:Ion in the plasma is led out from an ion led-out port 1a of a plasma slit 1 of a plasma chamber 4 to form an ion beam. In this case, the slit 1 of the chamber 4 is insulated from other parts of the chamber 4 by an insulating spacer 11, and a potential difference VS is generated between the slit 1 and other parts of the chamber 4 by a slit applying power source 15. Adhered material, accumulated in the slit 1 during the operation of the ion source, is thereby sputtered by the positive ion in the plasma and eliminated to prolong the lifetime of the ion source. Furthermore, since the ion lead-out port 1a is not blocked due to accumulation of the adhered material, area of the port 1a is not changed, and a change of the quantity of the lead-out current with elapse of time is reduced to form the stabilized ion beam for a long time.
