Abstract: PURPOSE: To obtain a cured article having well-balanced lightweight and cutting properties, surface and mechanical strengths, by hot-curing a blend of an epoxy resin, specific amounts of glass microballoons, and silas balloons, and a curing agent.  
     CONSTITUTION: An epoxy resin having one or more epoxy groups in the molecule is incorporated with (A) glass microballoons having a specific gravity of 0.2W0.4 and a particle size ≤200μ comprising borosilicate or silica glass and (B) 10W50% by wt. based on (A) of silas balloons having a specific gravity of 0.1W0.4 and a particle size ≤600μ to give the total content of (A) and (B) of 30W60% based on the whole composition. The composition is then kneaded with a polyamine or acid anhydride type curing agent, e.g. triethylene tetramine, filled in a mold of given shape, and hot-cured. The resulting article is suitable for synthetic wood, particularly a master model, and reusable because of high scratch resistance.

Title: Optoelectric signal converter
Inventor: MORI TOSHIHIKO
IPC: H01L31/10
Filed: 1991-03-26
Abstract: PURPOSE:To convert an optical signal to an electric signal at a high speed by preventing arrival of carriers of a first resonance level, to be allowed in a resonance tunneling emitter barrier region, to a collector region whereas allowing arrival of carries of a second resonance level. CONSTITUTION:Even of electrons of a first level E1 are passed through a barrier layer 16 by tunneling, the electrons are blocked by a collector barrier 14. The electrons blocked to be transported are dropped in a base region 15 to become a base current. A barrier height and a substantial barrier width of the barrier 14 are set to a level for forming a sufficient barrier for the electrons of the level E1 but not becoming a substantial barrier for the carrier of a second level. Thus, when the electrons having an energy of a second level E2 in an emitter barrier structure are passed through the layer 16 by tunneling, the electrons skip the barrier 14, and advance to collector regions 12, 13. Thus, an optoelectric signal converter having high performance and high reliability is obtained.
