Title: Rotor of embedded structure and manufacture thereof
Inventor: SUMIYA NAOYUKI
IPC: H02K15/02
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent the damage to low permeability material when laminated members are inserted by embedding the laminated members, wherein the low permeability material is held between highly hardened materials in the inside of a rotor core for the rotor having the embedded structure. SOLUTION: A rotor 1 is constituted of a shaft 2, a rotor core 3 and laminated members 4 embedded inside the rotor core 3. The laminated member 4 comprises a high hardened material 5, which is as hard as the material of the rotor core 3, and a low permeability material 6, which is softer than the material of the rotor core 3. The laminated member 4 is laminated without a gap in the vertical direction in the axial direction of the rotor 1. The rotor 1 constituted in this way has the laminated members at four places. Magnetic flux is made to flow readily at the gap between the laminated member 4 and the laminated member 4. The magnetic flux is hard to flow in the axial direction, wherein the laminated member 4 is embedded. Iron is used for the highly hardened material 5, a permanent magnet is used for the low permeability material and iron is used for the material of the rotor core 3.  Thus, the damage to the low permeability material of a reluctance motor is prevented.

IPC: G01S13/50
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To provide an automatic door sensor that can discriminate an automatic door front passing person from an automatic door passing person.

Title: Excimer-laser oscillation apparatus
Inventor: KOSUGI SHINICHIRO
IPC: H01S3/03
Filed: 1992-11-18
Abstract: PURPOSE:To provide an excimer-laser oscillation apparatus which can be operated repeatedly at short-time intervals. CONSTITUTION:In an excimer-laser oscillation apparatus, one pair of upper and lower main discharging electrodes 1 and a plurality of pairs of auxiliary ionization electrodes 4 are installed at a discharge part. Positions of gaps G for the individual auxiliary ionization electrodes 4 are changed up and down alternately, and they are formed to be zigzag as a whole. Spherical impulse waves are generated by a discharge at the parts of the individual gaps G. The spherical impulse waves are changed to cylindrical impulse waves after they have been bumped againt the neighboring spherical impulse waves. When the cylindrical impulse waves are strong, an irregularity in the density of a laser gas becomes large, and a bad influence is caused on a next discharge and a laser oscillation. However, since the positions of the neighboring gaps G are displaced up and down, the neighboring spherical impulse waves are bumped after the spherical impulse waves have become weak. As a result, only the weak cylindrical impulse waves are generated and the title oscillation apparatus can be operated repeatedly at short-time intervals.
