Title: Armature winding of linear motor
Inventor: ENDO KENJI
IPC: H02K41/02
Filed: 1991-07-11
Abstract: PURPOSE:To lighten a load on a power supply and transmission path by reducing reactive power generated at the time of applying power to an armature winding. CONSTITUTION:Because an armature winding 3 is a full pitch winding and double-layer winding composed of an upper winding 3a and lower winding 3b and electric current with the same phase and same direction flows through the upper and lower windings and attraction is applied between both windings, it is sufficient to provide the upper part of a groove 10 with a thin non-metallic cover 11 so that the height of the groove 10 can be reduced and reactive power caused by a leakage flux in a groove head can be decreased and a load on a power supply can be lightened.

Title: Piezoelectric resonator and piezoelectric filter
Inventor: KAIDA HIROAKI
IPC: H03H9/205
Filed: 1993-08-09
Abstract: PURPOSE:To attain the application of a resonator at the kHz bands and to ensure the characteristic of a wider band by securing such a constitution where a resonance part resonates by receiving the vibrations of a piezoelectric resonance unit via a vibration transmission part. CONSTITUTION:A vibration transmission part 1b is connected to a piezoelectric resonance unit 1a, and a resonance part 1c is connected to the part 1b. One of both ends of a coupling bar 1d is connected to the part 1c and a holding part 1e is connected to the other end of the bar 1d. The part 1b transmits the vibrations of the unit 1a to the part 1c. Thus the part 1c resonates by the vibrations received via the part 1b. In such a constitution, the part 1c resonates in a proper vibration mode like a flection mode, etc., and then eliminates the receive vibrations by the resonance. Thus it is possible to effectively prevent the vibrations from leaking out to the parts 1d and 1e which are connected to the outside of the part 1c.
