Title: Semiconductor laser
Inventor: UENO YOSHIYASU
IPC: H01S5/00
Filed: 1993-12-27
Abstract: PURPOSE:To lower the electric resistance for cutting down the Joule heat generated in ridge parts by forming striped ridges in (1, 1, 0) directions. CONSTITUTION:A multilayered epitaxial layer including at least the first conductivity type AlGaInP clad layer 7, an active layer 6 and the second conductivity type AlGaInP clad layer 5, striped ridges and a pair of laser ends are successively formed on the first conductivity type GaAs substrate 9. At this time, the active layer 6 is composed of AlGaInP in disordered state while striped ridges are former in (1, 1, 0) directions. The light emitting efficiency of this inverse mesa type disordered semiconductor laser is slightly lower than that of conventional normal mesa type ordered laser but electric resistance is also low. Accordingly, the Joule heat generation can be cut down less than conventional one when the optical output is higher thereby enabling the oscillation characteristics to be enhanced.

Title: Tape reel
Inventor: URAYAMA KIYOSHI
IPC: G11B23/037
Filed: 1988-12-28
Abstract: PURPOSE:To reduce builtup manhour and molding cost and thereby secure such a tape reel as in low cost by molding both upper and lower flanges solidly with an injection molding die with a slide core. CONSTITUTION:A tape reel 1, having a bladelike upper flange 3 and a disklike lower flange 4 solidly, is molded by means of a so-called one-shot process by an injection molding die unit 5 with slide cores 10a, 10b. Since this upper flange is enough to merely regulate a part of the winding surface of a magnetic tape T rolled by a reel hub 2 so as to prevent it from jumping out, it fully functions with a narrow blade form. Accordingly, resin material is economized so that material cost is thus reduced. In addition, since there is no process for joining these upper and lower flanges together, a manufacturing process is curtailed, and with these advantages, such a tape reel as in low cost is made manufacturable.
