Abstract: PURPOSE:To reduce the heat generation due to leakage magnetic flux in a rotary electric machine by forming a retainer for retaining a core of a rotary armature to fix it to a shaft of a coil end support made of a nonmagnetic material and a stationary section made of a magnetic material, to a shaft. CONSTITUTION:A retainer 5 for retaining a core 1 of a rotary armature from both sides to fix it to a shaft 2 is formed by shrink-fitting in combination of a cylindrical portion 5a made of a nonmagnetic material such as a stainless steel for fixedly placing a coil end 3b of an armature winding 3, and an annular plate portion 5b made of a magnetic material for fixing it to the shaft 2 via a key 6. Accordingly, an eddy current generated in the portion 5a due to the leakage magnetic flux of the coil end 3b can be almost eliminated to extremely reduce the heat generation due to the eddy current, thereby improving the reliability, and improving the yield of manufacturing the retainer 5 inexpensively.

Inventor: TAKAHARA HIROSHI
IPC: F16H19/04
Filed: 1988-09-01
Abstract: PURPOSE:To shift or revolve a thin film constitution body smoothly and reduce the frictional coefficient between a substrate and the thin film constitution body by arranging the thin film constitution body on a glass substrate and forming a superconductive thin film on the constitution body. CONSTITUTION:Since a thin film constitution body such as thin film gear has a superconductive thin film 6 on the surface, said constitution body repels the magnetic force lines of a magnet 8 because of the diamagnetic property, and the thin film constitution body is magnetically floated up. Then, the magnitude of the magnetic floating-up quantity is adjusted by varying the position of the magnet 8 or the magnitude of the magnetic force. Since no friction is generated between a substrate 7 and the thin film constitution body, the movement of a piezoelectric element, etc., can be transmitted to the revolution movement of the thin film gear 5 free from damping. Further, the thin film mechanical device has the substrate 7 formed from a glass substrate having the superor smothness and plainness, and when the friction is small, the need of forming the superconductive thin film 6 is obviated, and the need of the magnet 8 in the operation of the thin film mechaical device is obviated.

Title: Cooling device for energy dispersion type x-ray detector
Inventor: TAIRA MASAYUKI
IPC: H01L31/09
Filed: 1990-08-21
Abstract: PURPOSE:To reduce capacity of a cooling tank by filling the inside of the cooling tank connected to an energy dispersion type X-ray detector with a solid or a liquid metal having no phase change in a temperature range from a room temperature to a liquid nitrogen temperature, and cooling aforesaid metal under the liquid nitrogen temperature. CONSTITUTION:The inside of a cooling tank is filled with a metal 8, which becomes a solid in the range from a room temperature to a liquid nitrogen temperature (300K to 70K), for instance, lead, to directly cool aforesaid metal by a cooling device so as to overcool under a liquid nitrogen temperature. Specific heat of lead is 0.1 (J/g-K), however, its concentration in a solid is large as 11 (g/cm<2>). However, according to comparison with formerly used liquid nitrogen, a regenerating effect (product of specific heat and concentration) per unit mass is about the same. Accordingly, when lead having larger concentration than liquid nitrogen is used as a cooling medium, capacity of a cooling medium tank can be small constituted. Since a metal such as lead generates no phase change in a very low temperature, the cooling device can be made small-sized.
