Title: Semiconductor light emitting element
Inventor: FUKUZAWA TADASHI
IPC: H01S5/026
Filed: 1984-01-17
Abstract: PURPOSE:To modulate the intensity of light at voltage pulses by controlling the oscillation of a laser element by means of a control electrode by a method wherein semiconductor laminated regions oscillating laser having conductivity types reverse to each other and an insulation gate type FET whose laser element part is electrically connected are provided in integration. CONSTITUTION:Each layer of a clad layer 2, an active layer 3, a clad layer 4, and an impurity region 5 is successively formed on the upper surface of a semiconductor substrate 1. An SiO2 film of a fixed thickness is formed on this region 5, and this film is etched in stripe form. Next, after growing a high resistant layer 6 again by an epitaxial method to a fixed thickness, n<+> regions serving as the source and drain regions are formed by ion implantation. Further, a region 13 is formed by diffusing Zn to a part serving as the current path of the laser part. The source electrode 9, gate electrode 10, and drain electrode 11 are vapor-deposited, and the p-side electrode 14 is formed on the opposite side of the substrate 1. Then, the oscillation of the laser element is controlled by means of the gate electrode 10, and then the intensity of light is modulated at voltage pulses.

Title: Cable carrier structure
Inventor: SAMEJIMA TAKAYUKI
IPC: H02G11/00
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To give degrees of freedom to the allowable bending diameter and mounting condition of a cable by making the bending diameter of a cable carrier easily changeable by constituting the cable carrier in such a way that, when the carrier is bent around its connecting section, lids come into collision with each other and become a stopper. SOLUTION: When one cable guide 3a of a cable carrier 3 is rotated around a rotating shaft 8, the slopes 22 of lids 3d come into contact with each other and become a stopper and, accordingly, the bending diameter of the carrier 3 is decided. Since the lids 3b are removable, the bending diameter of the carrier 3 can be changed easily by attaching another lids 3b having different sizes to the carrier 3. In addition, the bending diameter of the carrier 3 can be fixed by adjusting the face-contacting angle between the slopes 22 at the interfering sections of the slopes 22. When, for example, the lids 3b are changed to long lids 3b, the bending diameter of the carrier 3 becomes larger.
