Title: Low pressure discharge lamp
Inventor: TOUHOU MAKOTO
IPC: H01J61/33
Filed: 1980-08-22
Abstract: PURPOSE:To simply manufacture a discharge lamp with high mechanical strength and high emission efficiency by providing a double tube structure consisting of a cylindrical outer tube and noncircular cross sectional inner tube, arranging the inner tube between electrodes without sealing process, and using the inside of the inner tube as a discharge passage. CONSTITUTION:Metal caps 2 and 2' adhere to both ends of a cylindrical outer tube 1 and electrodes 3 and 3' are provided on these metal caps. On the other hand, the cross section of an inner tube 4 is rectangular or elliptical and the inner tube adheres to the inside of the outer tube 1. Both of its ends are opened and form a discharge passage. Therefore, the inside and outside of the inner tube 4 are always at the same pressure and free from the stress caused by the atmospheric pressure difference. The tube 4 is not damaged even if it has an extremely noncircular corss section. Besides, since discharge mainly takes place in this noncircular cross section, emission efficiency can be fully improved.

Title: Superconductive magnet device
Inventor: SATO AKIO
IPC: H01L39/04
Filed: 1986-05-20
Abstract: PURPOSE:To lengthen the life of a superconductive magnet device by folding to wind a heat exchange pipe in an inductionless manner in two winding to set an electromagnetic force generated between the exchanger and a superconductive magnet body at the time of quenching to substantially zero. CONSTITUTION:A heat exchanger 21 disposed in a superfluidity helium tank 2 is composed by folding to wind a Cu heat exchange pipe in a coil shape so-called in two-winding structure. When thus formed in the two-winding structure, the inductance of a heat exchange pipe becomes zero. Accordingly, even if a superconductive magnet body 4 is quenched, an induction current does not flow through the exchanger 21. Therefore, it can prevent the exchanger 21 and the body 4 from damaging at the time of quenching.

IPC: B32B7/02
Filed: 1987-05-12
Abstract: PURPOSE:To make it possible to simply obtain an interior part which is highly qualitative on external view, by wrapping a fabric material made of thermo- shrinkable fibers on a base material such as an instrument panel or the like, and by heat-treating the sheet so as to coat the latter onto the base material. CONSTITUTION:A fabric sheet material in which heat-shrinkable fibers are woven in wrapped around a base material 2 such as an instrument panel, a door lining or the like. A fabric composed of foundation yarn of Double Russel and a polyester group heat-shrinkable material mixed with the former is used as the sheet material. When the sheet material is heated at a temperature of about 80 deg.C for 1-5min, the sheet material is shrunk so that the sheet is close- contact with the entire outer surface of the base material 2. In comparison with a sheet stretching method with the use of a conventional vacuum forming process, the sheet material can be thinned around the corner parts of the base material so as to prevent lowering of the qualitative appearance thereof, thereby it is possible to simply obtain an interior part having a highly qualitative appearance.
