Title: Anti-freezing device of cooling water channel
Inventor: SAKAGAMI MITSUHIRO
IPC: B23K9/32
Filed: 1978-07-28
Abstract: PURPOSE: To prevent water from freezing in the cooling water line and damaging apparatus by branching the cooling water line used for arc welders, etc. and expelling the water of the cooling water line, etc. with compressed air.  
     CONSTITUTION: A hose 11 connected to gas source 10 is connected to a gas source 19 on the way of the cooling water supply hose 5a of a welding torch 2. Solenoid valves 13, 14 are mounted to the gas line hose 11 and cooling water supply hose 5a, respectively. When the use of the welding torch 2 is finished, the solenoid valves 13, 14 are operated to send the compressed air from the gas source 10 to the supply hose 5a and torch 2. Since the water in the hose 5a and welding torch 2 is expelled by the compressed air, there is no possibility of damaging by freezing.

Title: Magnetic levitation type suspension apparatus
Inventor: TSUKAMOTO OSAMI
IPC: B60L13/06
Filed: 1989-04-13
Abstract: PURPOSE:To enable the stabilized control of a levitation gap and to eliminate electromagnetic noise by controlling the coil current of a levitation side coil unit. CONSTITUTION:A primary coil A on the supporting and fixing side is connected and linked in a guide rail manner to the under surface of the horizontal arm 2 of a support 1. A secondary coil B is provided on a levitation body 5 and a gap detection means for measuring a gap from the primary side coil A is provided moreover. When a three-phase symmetric AC current flows through the primary coil A, said three-phase symmetric AC current flows also through the secondary side coil so that an attraction force without three-phase AC component is generated and said electromagnetic noise disappears. The size of said gap is controlled by changing the current of the secondary side coil B through a feedback signal from said gap detection means. Thus, the regulation of gap can be made freely and automatic positioning characteristics on the levitation side are improved relative to the fixing side.

Title: Brake lining holder for split lining-disk brake
Inventor: ETSUKARUTO ZAUMUBUEEBAA
IPC: F16D65/02
Filed: 1984-05-10
Abstract: A brake lining carrier particularly for disk brakes having divided lining elements has a base plate on which is positioned an intermediate plate to support a carrier plate upon which is attached the friction lining. The intermediate plate has a number of indentations which form bulges. Bulges result in a certain degree of elasticity which provides a mobile elastic mounting support for the friction lining which may be made of sintered metal. The result is virtually noiseless braking with uniform surface application and without the generation of "hot spots".

Abstract: PROBLEM TO BE SOLVED: To take fluorescent photography of eyegrounds observing the circulation of fluorescence by infrared positioning. SOLUTION: When a photographing shutter 16 is depressed, fluorescent filters 5 and 8 are inserted into an optical path and a strobe light source 4 emits light to take a fluorescent image by a color video camera 12, which is stored once into a memory means 14.
