Title: Manufacture of semiconductor device
Inventor: TOBE YOSHIKIYO
IPC: H01L21/336
Filed: 1989-07-20
Abstract: PURPOSE:To prevent the deterioration of characteristics of a device by performing the formation of a gate electrode and an opening part and the etching of a gate electrode material layer with the same resist pattern as a mask, and removing the gate electrode material layer and a silicon layer by utilizing the selecting ratio of the etching. CONSTITUTION:The formation of a gate electrode 16 and an opening 14a and the etching of a gate electrode material layer 14 other than the gate electrode 16 are performed by using the same resist pattern as a mask. The removal of the gate electrode material layer 14 for forming high/low concentration impurity regions 18-21 and the removal of a silicon layer 17 are performed by utilizing the selecting ratio of the etching. Therefore, etching steps for the entire surface for forming side wall as in a conventional method are omitted. Thus, the effects due to etching on ground elements such as a field oxide film 12 and a P-type silicon substrate 11 and the like are suppressed. The deterioration of the characteristics of the device is prevented. The reliability and the yield rate can be improved.

Abstract: PURPOSE:To surely and stably braze perforated tubes for a heat exchanger consisting of Al (alloy) by blowing and spraying a brazing filler metal in a molten state by gas of a prescribed pressure toward the surface of the perforated tubes and sticking the brazing filler metal to the surface of the perforated tubes, thereby forming brazed films. CONSTITUTION:The brazing filler metal for forming the brazed films is required to have the m. p. lower than the m. p. of the perforated tubes A and fins 11 made of the Al (alloy) to be brazed, such as Al-Si and Al-Si-Mg. The gas for blowing and spraying the brazing filler metal 5 in the molten state may be the air or the inert gas, such as Ar or N2. The oxidation of the brazing filler metal can be prevented if the inert gas is used. The pressure of the gas for blowing and spraying the brazing filler metal in the molten state is preferably >= 4 kgf/cm<2>. The perforated tubes in the state of the high temp. right after hot extrusion is more preferable as the adhesive strength of the films is higher with such tubes. The brazed films are formed on the surfaces of the perforated tubes in such a manner without requiring fluxes.

Filed: 1991-07-26
Abstract: PURPOSE: To provide a new 1,3-diphenyl-2-pyrazoline-derivative which shows the higher Stokes transition than the known substance as scintillator in the solution and solid polymer.  
     CONSTITUTION: The compound of formula I is obtained by allowing mesity vinyl ketone to react with the compound of formula II. In formula I, R 1  is electron donor substituent, in particularly N(CH 3 ) 2 , NH 2 , OH, OCH 3 , CH 3  or C(CH 3 ) 3 ; R 2  is CH 3 , OCH 3  or H. Because the wave length ranges of fluorescent radiation and absorption in this compound are more widerly separated each other than those of the known substance those overlap is generated only in case of high concentration of scintillator substance in solution. Besides, fluorescence-quantum yield and fluorescence decay time are within advantageous ranges of the known substance. Accordingly this compound is optimum to be used in chamber of large capacity having in particular aromatic solvent or in scintillator fiber of polymer as scintillator.

Inventor: OKUTSU TAKAHITO
IPC: F23N5/00
Filed: 1983-10-06
Abstract: PURPOSE:To enable reliable detection of ignition without being influenced by an ambient temperature, by a method wherein ignition is detected through detection of a change in an output voltage produced by oxygen concentration. CONSTITUTION:A sensor 1 is made of a material such as zirconia, and is an oxygen concentration battery type sensor which generates an electromotive force occasioned by a change in oxygen concentration, and detects ignition and incomplete combustion. A least minimum value detector part 24 of a microcomputer 23 in an ignition detecting circuit 21 inputs the output power voltage of a zirconia sensor, and decides whether the inputted voltage value is an extreme value. When it is minimum value, the detector part detects a least minimum value through comparison of a present minimum value Z (2) with a least minimum value Z (0) of preceding one and before. An ignition judging part 25 deducts the least minimum value Z (0) from a value Z (3) of a zirconia sensor, and when the result exceeds a predetermined ignition detecting voltage V, it is judged that ignition is made.
