Title: Wavelength conversion element
Inventor: TAKAHATA KIYOTO
IPC: H01S5/10
Filed: 1991-06-17
Abstract: PURPOSE:To reduce reflectance of an element edge face, to restrain Fabry-Perot oscillation inside an element and to realize a wavelength conversion element wherein input light power which is required for element operation is independent of operation wavelength by providing a window structure near the edge face of the wavelength conversion element having a distribution reflector. CONSTITUTION:An active layer 13, a saturable absorption layer 14 and an optical guide layer 15 are formed to stripes on a substrate 11. Buried layers 16, 17 are epitaxially formed in a periphery of the stripe to bury the stripe and a clad layer 18 is epitaxially formed thereon. One end of the optical guide layer 15 does not attain an element edge face, and a proximity of an edge face is buried with InP similar to a stripe side to form a window region 42. Therefore, when light propagated through the optical guide layer 15 enters an InP layer, optical power distribution extends due to difference of equivalent refraction factor. In reflection light which is reflected in the element edge face, little light is combined with the optical guide layer 15 and reflectance is reduced.

Title: Ink-type wire dot printer
Inventor: HIRASHIMA YASUHITO
IPC: B41J11/057
Filed: 1982-08-20
Abstract: PURPOSE:To enable to constantly achieve clear printing free from scattering of ink, by constituting a platen of a plurality of surfaces differing in hardness. CONSTITUTION:The platen 13 is bisected into platens 13a, 13b, which differ in hardness. When a recording paper 4 is a single-sheet paper, it is printed by locating the platen 13a at a position faced to the platen 13a, and when the recording paper 4 is a copying paper constituted of two or more sheets, the platen 13b is used. When the hardness of a rubber constituting the platen is low, drformation of a recording paper when receiving a dot becomes large, whereby an instantaneous rise in pressure is relieved, and the ink is prevented from being scattered. In addition, the contact between a tip surface of a wire and the recording paper becomes uniform, the ink is wastelessly transferred onto the recording paper, and the dot becomes dense and clear. When the recording paper is the copying paper, the paper itself produces an effect similar to that of a low-hardness platen because of its large thickness, so that a high-hardness platen is used.

Abstract: PURPOSE: To reduce the interference on an optical system by the reflection light beams from a target by irradiating the target with incident laser beams through the small reflection mirror supported by a small radius diffusion lens at the center of a converging lens and a diffusion lens. CONSTITUTION: A laser luminous flux 32 emitted from a laser is reflected by a small reflection mirror 30 on an optical axis 16, goes through a diffusion lens part 34 which supports a reflection mirror 30, a converging lens part 36 of large diameter converging lenses 38 and 40 and emits as a converging luminous flux 48 and scans a target (such as a bar code) as a small diameter beam by the laser scanning device. The reflected light beams become diffused light beams 50, go through the entire surfaces of the lenses 38 and 40 excluding the part 36 and converged, go through an optical band filter 20 and are made incident on a photodetector 18. Since the diameters of the mirror 30 and part 34 are smaller than the diameters of the lenses 38 and 40, the interference caused by the reflection light beams from the target is reduced.
