Title: Rotor for superconducting rotary electric machine
Inventor: MATSUO YOSHIHIRO
IPC: H02K55/04
Filed: 1987-11-11
Abstract: PURPOSE:To make the second moment of area of a coil mounting shaft uniform and to enhance the cooling effect of a superconducting field coil by axially providing a plurality of rigidity compensating slits perpendicularly to the axis on the pole of the coil mounting shaft. CONSTITUTION:A plurality of rigidity compensating slots 19 formed perpendicularly to an axis are formed on the pole of a coil mounting shaft 2. Radial holes 20 for connecting the slits 19 to liquid helium reservoir 16 are formed. Since sections in which its second moment of area are reduced by the slits 19 and disposed axially in the number corresponding to that of the slits, the deflection in the direction of the pole of the shaft 2 due to gravity is increased, and equivalently second moment of area of the shaft 2 becomes uniform. The liquid helium is easily filled in the rigidity compensating slits 19 through the radial holes 20, moved circumferentially along the circumference of an outer cylinder 7 to a superconducting field coil.

Inventor: TAKESHITA TAKUO
IPC: B22F1/00
Filed: 1986-12-01
Abstract: PURPOSE:To enable RCo5-type rare earth alloy powder to be manufactured without a crushing process which would cause oxidation or stress, by using Co powder having a specific average particle size as a material as said alloy powder. CONSTITUTION:Powder of an oxide of a rare earth element (designated by R), Co powder and a reducing agent are blended and mixed in predetermined proportions. The powder mixture is heated and reduced within an atmosphere of an inactive gas and subsequently the residual reducing agent is removed. The Co powder used as a material should have an average particle size of 1-8 mum. In this manner, RCo5-type rare earth alloy powder having an optimum average particle size of 3-10 mum can be manufactured without using a crushing process which would cause oxidation, strain or cracks of the powder. Further, after washing the alloy powder with water to remove the residual reducing agent, the alloy powder can be directly coated with an anti-oxidation film without being subjected to drying or particle size regulating process.

Title: Method for controlling carbon content in metallic sintered body
Inventor: TOMITA SHOICHI
IPC: B22F3/10
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To control a metallic sintered body to a desired carbon content at high accuracy regardless of the history of a degreased body by removing the carbon content and oxygen content in a green compact before sintering as much as possible. SOLUTION: The degreased green compact contains carbon and oxygen mainly as a metallic oxide. The carbon can almost be removed by a hydrogen reduction below 1000 deg.C, but the oxygen remains considerably depending on a kind of the degreased body. A large part of the oxygen is removed in any degreased body by the hydrogen reduction in a prescribed time by slowly raising the temp. from 1000 deg.C to a sintered body producing temp. The sintered body producing temp. is desirable to be in the range of 1150-1250 deg.C and the temp. raising time is sufficient to about 2-4hr regardless of the kind of degreased body. Therefore, it is recommended to execute two steps of the hydrogen reduction process below 1000 deg.C and the hydrogen reduction process raising the temp. to the sintered body producing temp.  By this method, since the influence of the history of the degreased body and the material of metallic powder can almost perfectly be rejected, the carbon content in the sintered body can easily be controlled to the desired value in the high accuracy in the same operation.

IPC: G11B27/28
Filed: 1991-11-05
Abstract: PURPOSE:To make the device convenient by recording the absolute time later without erasing a start IDX end mark. CONSTITUTION:An FG counter is reset and then, counted while on-track reproducing. Based on a track number from a point A', the A-TIME of the point A is calculated and recorded. Then, an end mark B or a next start ID is detected by the scanning of an offtrack reproducing. The rough position of a point B is decided from a counted value, but a virtual point B' (the recording finishing end position of the A-TIME) right before a specified value is memorized. Then, the counted value is rewound to the point A' below 0, the A-TIME is read out by the on-track reproducing again and the recording of the A-TIME is started from the point A'. When it reaches the point A, the start ID is recorded, as well. The recording of the A-TIME is continued even after the recording of the start ID is finished and when it reaches the point B', the same processing is repeated considering the point B as the point A with the point B' as a new reference point A'.
