Filed: 1988-07-22
Abstract: PURPOSE:To improve the performance and integrity of a device substantially by a method wherein single crystal silicon having a conductivity type different from that of its lower layer is made to grow from column type apertures to fill the apertures and a flat single crystal silicon film is formed on insulating films. CONSTITUTION:After elements are formed on a P-type, which is a first conductivity type, single crystal silicon layer 3, insulating layers 4 are formed. N-type single crystal silicon 5 is made to grow from column type apertures by epitaxial selective growth to fill the apertures with the single crystal silicon 5. The surface is levelled by vapor phase etching and the growth is continued again and, finally, vapor phase etching is again performed to cover the surface of the insulating layers 4 with flat single crystal 6.

Title: Constant flow rate valve
Inventor: KATO OSAMI
IPC: B01D35/04
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To facilitate variation or a constant flow rate area and to reduce a size of a constant flow rate valve by a method wherein a resilient substance formed in a shape of a bag with a bottom is securely contained in a case, in such a manner that an opening end is situated in the water inflow direction of the case, by a support member arranged in the case, and a flow passage is formed between the resilient substance and the case. SOLUTION: Fluid is fed through a flow passage 3 running between a resilient substance 1 and a case 2. When a water pressure is increased, a flow rate of water is approximately linearly increased with increase in a water pressure but when the water pressure exceeds a critical pressure, the sides of the outer peripheral parts 14 and 14' of the resilient substance 1 fronting on the flow passage are resiliently deformed due to a pressure difference between the interior of the bag of the resilient substance 1 and the flow passage to start closing of the flow passage. The resilient deformation is increased with the increase of a water pressure and more strongly closes the flow passage, whereby increase in a flow rate at a pressure exceeds a critical value is prevented from occurring and a flow rate of fluid is kept constant.  Further, resilient deformation of the resilient substance 1 is restored to its original state when the feed of water is stopped.
