Title: Discharge-excited short pulse laser device
Inventor: WAKATA HITOSHI
IPC: H01S3/038
Filed: 1985-02-18
Abstract: PURPOSE:To enable the obtaining of laser beams of good quality and high output, by a method wherein a current restriction element restricting the current to the second main discharge space is provided, and a good-quality laser beam resonated in this discharge space is amplified in the first main discharge space. CONSTITUTION:When the difference in potential between both ends of a capacitor 5 increases, first discharge is generated in the second main discharge space 19 of short discharge gap length. Since a coil 20 as the current restriction element is series-connected to this discharge space 19, the difference in potential between both ends of the capacitor 5 keeps on increasing, and finally discharge is started in the first main discharge space 12 of long discharge gap length. At this time, the laser beam is led to the discharge space 12 by a mirror 24; then, the enlargement in beam diameter is corrected by a convex mirror 25, and the dispersion angle by a concave mirror 26. Further, laser beams of uniform phase obtained by the discharge space 19 are amplified during reciprocation through the discharge space 12. This process can offer well-convergent laser beams of high output and uniform phase.

Title: Electric blower for electric cleaner, etc.
Inventor: MIMORI KIYOYASU
IPC: F04D25/06
Filed: 1978-03-17
Abstract: PURPOSE: To make the oscillatory amplitude of core itself smaller by giving damping by differentating each position in contact with housing by stacking stator core iron plates of different outward forms in the axial direction.  
     CONSTITUTION: The stator core housing 2 and the fan casing are integrally assembled alternately in the axial direction in such a way that the outsides of each iron plate come into contact with any one of the contacts a and b of the oscillating mode of the stator core 1. Thus, as the mode changes when the core 1 vibrates, the interface between the iron plates is shifted and thus damping by friction is given. By taking advantage of damping by the firction, the oscillation and noise of electric blower can be reduced by oscillatory effect without damaging to electrical characteristics.
