Title: Semiconductor laser device and its manufacture
Inventor: KASAI SHUSUKE
IPC: H01S5/16
Filed: 1989-03-13
Abstract: PURPOSE:To prevent end face breakage by providing an inclined forbidden band width layer whose forbidden band width increases gradually with the distance from a cleavage plane, on at least one cleavage plane of a laminated construction. CONSTITUTION:A laminated construction 12 containing an active layer is formed on a board 11. After the formation of the laminated construction 12, a laser resonator 15 is obtained by cleaving it. Besides, an inclined forbidden band width layer whose forbidden band width increases gradually with the distance from a cleavage plane 101 is formed on at least one cleavage plane 101 by vapor growth. Accordingly, as the carriers existing in the vicinity of a light- emitting end face are driven away in a short time from the vicinity of the end face not only by normal diffusion but also drift, the probability of their contributing to the heat generation through the surface level is extremely small. And, this makes it possible to prevent the end face from breaking down efficient ly.

IPC: H04B7/204
Filed: 1991-03-25
Abstract: PURPOSE:To prevent the reception processing of an ACK signal at a transmission station from being increased even when the ACK signal representing that each reception station is normally received is returned from each reception station. CONSTITUTION:A transmission station 1 includes repeater station designation information to designate reception master stations 31,41 as repeater stations into a transmission data and sends the result to each of reception stations 31-33.

Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a small and low cost sensor for detecting a temperature and level of a liquid easy to handle by a constitution wherein a liquid temperature sensor and a liquid level sensor are integrally formed. SOLUTION: A liquid temperature sensor 2 is provided to an end section 1a in a protection case 1 and a liquid level sensor 3 is provided to a target liquid level position 1b of a liquid 11 in a tank 8.

Abstract: PURPOSE:To improve the quality of a screen image by preventing a color irregularity, etc., from being generated owing to a non-lens surface which is nearly perpendicular to a lens main surface R. CONSTITUTION:When a lens surface Lm which has a prism angle Am to a mold main surface Rm is cut, the sum of the inclined angles theta of the prism Am and a cutting tool 12 becomes nearly 90 deg. and the non-lens surface is cut at an angle exceeding Am+theta by a conventional method after a lens surface Lm is cut over a specific outward peripheral range from the position where the non-lens surface is cut with the back surface of the cutting tool to become a specular surface, thereby forming a non-lens surface Nm having a non-lens surface angle Bm. This mold is used to manufacture the Fresnel lens and the non-lens surface N of a corresponding prism part P is formed at a non-lens surface angle where far-axis light projected from the Fresnel lens is not reflected and stray light in the lens is hardly projected.
