Filed: 1986-11-25
Abstract: PURPOSE:To obtain excellent high speed modulation characteristics and excellent efficiency by providing a conductivity type block layer between a high resistance semiconductor layer and a conductivity type semiconductor substrate and by making the block layer of an opposite conductivity type to that of the substrate and to be a depletion layer. CONSTITUTION:After an active region is made into a mesa state of transverse width approx. 1 micron by chemically etching double hetero crystal obtained in a stripe state by a normal method, a conductivity type block layer 16 made of Zn doped InP is grown by a hidride vapor growth, and then, a high resistance semiconductor layer 15 made of Fe doped InP is formed. If a current is given to the p-side electrode 17 and the n-side electrode 18 of such a structure semiconductor laser, the current flows in a current path (a mesa stripe state double hetero structure consisting of a p-clad layer 12, the active region 11 and an n-buffer layer 13) but does not flow in a current block region (consisting of the high resistance semiconductor layer 15 and the conductivity type block layer 16). For this reason, oscillation is made with little leakage current to a high output In this structure, the capacitance of the current block region is also made very small, a time constant is made very short and high speed modulation is possible.

Title: Foamed cushioning material
Inventor: NAKANISHI MOTOYASU
IPC: F16F1/37
Filed: 1987-11-06
Abstract: PURPOSE:To obtain a composite foamed cushioning material which can be produced inexpensively, is relatively compact and excels in cushioning property, by dispersing small gel balls based on a silicone resin of a penetration in a specified range in the cells of a foam. CONSTITUTION:This foamed cushioning material is formed by dispersing the following small gel balls in the cells of a foam. A silicone resin stock solution is discharged dropwise from a nozzle into the depth of water, allowed to take a substantially spherical form by the ambient water pressure and allowed as such to gel in the water to form small gel balls based on the silicone resin and having a penetration of about 50-200. Since the gel-like substance based on the silicone resin is dispersed in the cells of a foam in the form of small gel balls, it can exhibit a cushioning property which cannot be attained by a simple foam and is relatively light and compact. Because the gel balls are contained in the foam in such a manner that they are enveloped in some of the cells, they need not be sealed in an outer packaging material in a separate step and can be handled in the same manner as that for a conventional foam.
