Title: Gan compound semiconductor device and manufacture thereof
Inventor: NISHIO JOSHI
IPC: H01S5/00
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the crystal property of a gallium-nitride-based compound semiconductor growing on a buffer layer at a high yield rate, by constituting a buffer layer on the side of a substrate in the two or more layers with GaAlN, and constituting the butter layer on the side of a GaN-based compound semiconductor layer by InGaN in the laminated structure. SOLUTION: On a substrate 11, GaXAl1-x (0<=x<=1) as a first buffer layer 12 and Iny Ga1-y N (0<=y<=1) as a second buffer layer 13 thereon are laminated. A gallium-nitride-based compound semiconductor crystal 14 is grown thereon. The structure of an epitaxial wafer is formed in this way. After the growing nucleus is formed of the first buffer layer 12 by introducing the second buffer layer 13, the crystal defect present in the first buffer layer 12 can be embedded without drawing the growing surface at the layer, wherein the growing speed vertical to the growing direction of the thin-film crystal is relatively high. Therefore, the defect density of the gallium-nitride compound semiconductor or growing thereon can be decreased.

Title: Compound-type water meter
Inventor: HANSU PEETAA DEBUARUTO
IPC: F16K1/06
Filed: 1994-03-08
Abstract: PURPOSE: To minimize force of a spring holding a valve head in the closing position and to shorten its length by using a very narrow main flow packing sheet, providing a pan-shaped edge in a shutting off mechanism, and narrowing a ring type chamber side face conically. CONSTITUTION: When a differential pressure is increased further in compliance with increase in quantity of water flowing through an auxiliary pipe, a shutting off mechanism 9 starts moving against the force of a compression spring 12, while an elastic lip packing 27 is still closed. However, a pan-shaped edge 17 of the mechanism 9 reaches the center of a slit zone 51 through a neutral zone 14. In this process, an auxiliary flow shifts the edge 17 into a conical weir stepped part, 52. In this case, a narrow width ring slit 20 between the edge 17 and a ring type chamber side face is continuously reduced. Therefore, the edge 17 moves to end part back side of the stepped part 52, the packing 27 is separated from a sealing edge 49, and the main flow water passes through a main water measurement device 1 and a main flow penetrating zone 22.  This opening process is carried out very quickly, so that no measurement error is generated.
