Title: Harmonic producer
Inventor: KUZUMOTO MASAKI
IPC: H01S3/109
Filed: 1989-01-24
Abstract: PURPOSE:To produce a high-output harmonic with high efficiency by confining light which has wavelength other than the finally required harmonic with >=2 reflecting surfaces and arranging a wavelength converting element between the reflecting surfaces. CONSTITUTION:A omega wave produced by a omega wave producer 1 is confined by the resonator consisting of mirrors 31, 33, and 34 and a 2omega wave produced by the wavelength converting element 2 is projected from the mirror 34 which has a transmission coating for the 2omega wave to a mirror 35. The 2omega wave is confined between the mirrors 35 and 33 and part of it is converted by the wavelength converting element into a 4omega wave. The mirror 34 is not provided with a reflection coating for the 4omega wave, so only the produced 4omega wave is guided out. Thus, the energy of the omega wave and 2omega wave is confined between the mirrors, so only the 4omega wave light can be guided out with high efficiency, and a large output is easily obtained without damaging the wavelength converting element.

Title: Printing line position adjustor
Inventor: NAKAMURA SHINYA
IPC: B41J11/24
Filed: 1984-01-31
Abstract: PURPOSE:To enable a printing line position to be accurately positioned with a simple construction, by a method wherein a motor frame is turned around the axis of a platen together with a platen motor by a position-adjusting motor, and the platen itself is arbitrarily rotated. CONSTITUTION:A switch 16 is turned ON, and rotation of the platen motor 10 is transmitted through gears 9, 8 to intermittently rotate the platen 6, thereby feeding a paper at as fixed pitch. In starting printing, when the printing line on the paper is staggered relatively to the tip of a printing head 3, the platen motor 10 is stopped, the back lash between the gears 8, 9 is fixed by meshing a detent 11 with the gear 8, and a switch 17 is turned ON to drive the position-adjusting motor 15, thereby turning the motor frame 7 a predetermined angle together with the platen 6. Thereafter, the printing line position can be accurately adjusted without need for manual operation. Accordingly, it is unnecessary to provide clutches in a power transmitting path for the platen and the motor frame, and the construction can be simplified.
