Title: Burner device
Inventor: KANEHARA NOBUYUKI
IPC: F23N3/00
Filed: 1984-02-22
Abstract: PURPOSE:To contrive to establish clean combustion by a structure wherein primary and a secondary burners and an oxygen concentration detecting sensor are provided. CONSTITUTION:A burner A1 has a flame port part 6 formed by wire mesh inside an external cylinder 5. A burner B8 also has a flame port part 12 formed by wire mesh. In addition, an oxygen concentration sensor 13 consisting of SnO2, TiO2, ZrO2 or the like is provided at the position, which is above the flame port part 12 of the burner B8 and at the same time near the lower end part of the flame port part 6 of the burner A1. In this case, because the primary excess air ratio of the burner A1 is set larger than that of the burner B8, the incomplete combustion state caused from the shortage of air due to oxygen deficiency and the like occurs earlier at the burner B8 than at the burner A1. The sensor 13 detects the combustion state of the burner B8 and stops the combustion, resulting in enabling to detect the combustion state more surely and more earlier. Furthermore, because the complete all primary surface combustion or combustion, which necessitates no secondary air, is performed, low NOx and low CO clean combustion can be established.

Title: Method of liquid-phase epitaxy
Inventor: MORIMOTO TAIJI
IPC: H01L21/208
Filed: 1986-02-13
Abstract: PURPOSE:To obtain a multi-layer construction having different thicknesses in some sections, by forming grooves on a growing face parallel with each other in a striped pattern and limiting the speed at which an epitaxy layer is grown in the region between these grooves for the purpose of controlling the thicknesses of the layer. CONSTITUTION:When a semiconductor substrate is subjected to liquid-phase epitaxy, the growth progresses more rapidly on a curved or recessed region than on a flat region of the substrate. Accordingly, on a semiconductor substrate 10, the epitaxy progresses more rapidly in parallel grooves 20 and 21 than on the other regions. The growth occurring in the grooves 20 and 21 consumes As contained in growing melt neighboring the grooves, whereby the growth is restrained in the regions surrounding the curved regions, namely in the grooves. Therefore, the growth on the central region 30 between the two grooves 20 and 21 is restrained substantially under the influence of the grooves 20 and 21. Consequently, an epitaxy layer 11 as shown in the drawing can be obtained.

Abstract: PURPOSE:To avoid the system breakdown at switch of systems by separating a fixed disk (HDD) which holds each system information from an HDD which holds various data. CONSTITUTION:An HDD 5 for system A holding the information on a system A is used together with an HDD 7 for system B holding the information on a system B, and a common HDD 6 holding various data respectively. For the HDD 5 the system information is read out by a central central unit CPU 1 of the system A while this system is working and all data are written into the HDD 6. When the system A is switched to the system B due to the trouble of the system A, the system information on the HDD 7 is read out by a CPU 2 of the system B. At the same time, the data stored in the HDD 6 are all read out and all data on the system B are written into the HDD 6. Thus, the danger of the system breakdown is eliminated and the continuance of data is secured after the switch of systems.
