Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a self-adhesive tape which is obtained by applying, onto a substrate surface, a solution of a rubber-based self-adhesive wherein natural rubber is dissolved in a mixed organic solvent composed of specified amounts of an aromatic organic solvent and aliphatic organic solvent, and drying to form a rubber-based adhesive layer thereon, and is improved especially in initial adhesive force under low temperature conditions. SOLUTION: 100 pts.wt. of natural rubber is dissolved in 200 to 350 pts.wt. of a mixed organic solvent composed of 20 to 60 wt.% of an aromatic organic solvent, preferably toluene, and 40 to 80 wt.% of an aliphatic organic solvent, preferably normal hexane, to obtain a rubber-based adhesive solution. The solution is applied onto at least one side of a substrate made preferably of a 40 to 100 μm thick Japanese paper, non-woven fabric or synthetic resin sheet and dried to form a rubber-based adhesive layer preferably having a thickness of 40 to 80 μm. More particularly, by using the aromatic and aliphatic organic solvents at a specified mixing ratio, an adhesive force can be controlled while keeping miscibility with natural rubber and preventing gelation of the adhesive surface layer.

Title: Method for growing semiconductor crystal
Inventor: HAMAO NOBORU
IPC: C30B23/08
Filed: 1987-03-13
Abstract: PURPOSE:To grow a semiconductor crystal with a surface flattened on an atomic level by growing an AlGaAs layer on a substrate by molecular beam epitaxy, then stopping an Al beam to grow a thin GaAs layer, and then stopping even a Ga beam to transiently interrupt the growth. CONSTITUTION:An Al0.7Ga0.3As layer 2 is grown on a GaAs substrate 1 by molecular beam epitaxy. Only the Al beam is then stopped to grow a GaAs layer 3 to the extent of 1-2 atomic layers or thinner. The Ga beam is then also stopped to interrupt the growth, and the state is kept for about 1X2min. At this time, the Ga atom in excess of the surface atomic layer is diffused on the surface and forms a mixed crystal with AlGaAs, hence the content of Al in the surface atomic layer 7 is relatively reduced, the surface diffusion of the Al atom is promoted, and the crystal surface is flattened. As a result, when the Ga beam is again projected to grow the GaAs layer, the hetero-junction interface of GaAs/AlGaAS flattened at an atomic layer unit is obtained.

A screw stopping controller 7 outputs a stop signal 19 at a point of time wherein the deviation signals 15, 16 become smaller than the previously prescribed values. A gate 10 adjusts the roll gap in accordance with a closing command 20 for the screw down device 1 and said stop signal 19; then, the screw device 1 actuates to open or close the roll gap in accordance with a closing command signal 11 through a roll gap controller 2.
