Title: Wavelength conversion of laser light
Inventor: SOMA HIROTOSHI
IPC: H01S3/108
Filed: 1986-08-26
Abstract: PURPOSE:To omit preparation of a plurality of nonlinear optical crystals and to perform wavelength conversion of laser light only by rotation, by inputting the laser light into the X-Z plane of a beta-BaB2O4 single crystal so that the polarizing direction of the laser light is in parallel with Y axis. CONSTITUTION:An incident plane 1 of laser light of a beta-BaB2O4 crystal has a spherical shape. The crystal 2 is mounted on a stage 3. The stage is rotated, and a phase matching angle theta is set at an arbitray value. The laser light is inputted into the X-Y plane of the single crystal so that the polarizing direction of the light is in parallel with the Y axis. The beta-BaB2O4 single crystal has high conversion efficiency from the laser beam to coherent ultraviolet rays and also has a very large birefrigence. The third harmonic can be generated from the sum of the second harmonic and the fundamental wave. In this constitution, the phase matching angle theta can be adjusted only by rotating the crystal when the laser light undergoes wavelength conversion. Therefore, the incident light is not screened, and operation can be simplified.

Title: Sewing machine for automatically embroidering
Inventor: TAKENOYA HIDEAKI
IPC: D05B21/00
Filed: 1988-08-12
Abstract: PURPOSE:To form a skillfully embroidered pattern by equalizing seam intervals between blocks adjoining each other by providing an arithmetic unit for a second needle location computing the needle-locating point on a uncommon side of the blocks through vertexes of the blocks belonging to a second group and a basic pitch possible to set stationarily or voluntarily.

Title: Diffusion joining method
Inventor: HIRANE TERUO
IPC: B23K20/16
Filed: 1982-11-17
Abstract: PURPOSE:To improve joint strength by interposing an insert material between joining members, applying heat energy and electromagnetic induction energy thereto in a vacuum to melt the insert material then solidifying the same thereby eliminating formation of oxide from the joining boundary. CONSTITUTION:A heat resistant alloy is used for a joining member, and more particularly a gamma' precipitation phase hardening type heat resistant alloy is effective.
