IPC: B01D53/02
Filed: 1981-06-04
Abstract: PURPOSE: To reduce required driving power per unit product and to improve production efficiency by including waste gas contg. much of easy to adsorb component gases generated in a discharging state of an adsorbing and separating method for gaseous mixtures in gaseous raw material.  
     CONSTITUTION: The air past a filter 1 is compressed with a compressor 2, and is removed of impurities in a pretreating device 3 and is cooled down to a prescribed temp., after which it enters an adsorption tower 11, where it is adsorbed selectively of O 2  by adsorbents 17. The remaining N 2  is discharged as a non- adsorbed gas C. In the gas releasing stage of the adsorption stage, the waste gas E contg. a large amt. of O 2  is introduced from the tower 11 into a tank 6 by opening valves 41, 51, after which it is flowed through a compressor 8 and a cooler 9 and is included in a gaseous raw material B. In a desorption stage, valves 61, 71 are opened, and the O 2  adsorbed on the adsorbents 17 is desorbed through the gas C, whereby it is made into a gas D contg. much O 2 . This gas is discharged to the outside of the system. The towers 11, 12 repeat the stages of desorption, gas releasing and desorption alternately.

Abstract: PURPOSE:To control the production of a defect by reducing a heat treating step and to improve the reliability of an element by reducing the oxidizing step by introducing an impurity into a substrate through an oxidized film, and controlling the thickness of the film to provide the step of controlling the density of an impurity region. CONSTITUTION:Ion implanted layers 24, 25 becoming a base low resistance region 28 and a diffusion source of a base diffused layer 27 are formed by ion implantation of the prescribed conductive type impurity in a substrate through a thin oxidized film 22a and a window 23. The densities of the layer 27 and the region 28 are determined by controlling the thickness of thin oxidized film 22a. Then, a CVD-oxidized film 26, to which an impurity is not introduced, is formed on the surfaces of thermally oxidized films 22, 22a and the layer 24 exposed via a window 23. Subsequently, the prescribed diffused heat treatment is executed, and the layer 27 and the region 28 having the prescribed impurity density and diffusion depth are formed in the N<-> type layer 21. The surface impurity density of the layer 27 is determined by the data obtained by the characteristics and the product test.

IPC: H01G4/32
Filed: 1988-04-06
Abstract: PURPOSE:To improve a corona discharge characteristic by a method wherein a capaci tor element is housed in a container and treated by a vacuum, sulfur hexafluoride gas (SF6 gas) is filled into the container in a vacuum state, the circumference of the container is then molded by using a synthetic resin, and two or more pieces of this container-housed capacitor elements are assembled and molded collectively by using the synthetic resin. CONSTITUTION:A capacitor element is housed in a container; it is treated by a vacuum; SF6 gas is filled into the container; after that, the circumference of the capacitor element is molded by using a synthetic resin 20. Since SF6 gas can be filled at high density around an edge face of a metal thin film on both end faces of a winding of the capacitor element, a corona discharge firing voltage can be increased around the edge face of the metal thin film on both end faces of the winding of the capacitor element. Since an electrode can be formed and an extraction wire can be connected in the air, these operations can be executed easily; the corona discharge firing voltage can be increased also in parts where dielectric strength is weak, i.e. in a void part between metallized films 5, 6 to be wound and in a part around the edge face of the metal thin film on both end faces of the capacitor element; accordingly, a molded capacitor whose breakdown strength is high can be obtained.

Abstract: PURPOSE:To reduce the labor to decide a control constant and to improve the control performance with a process controller, by using a compensator to output a manipulated variable for offset of the process feedback value to a process having the self-feedback. CONSTITUTION:An I-PD controller 1 supplies a target value signal (r) and an output signal (y) and outputs an operation signal u1.

Title: Semiconductor laser and manufacture thereof
Inventor: HORIKAWA HIDEAKI
IPC: H01S5/00
Filed: 1992-04-08
Abstract: PURPOSE:To efficiently supply a current only to an active layer in a groove and to operate in high efficiency with a low threshold value by using a GaAs layer having high resistance and formed by low temperature growth as a current blocking layer. CONSTITUTION:An n-type GaAs buffer layer 32 is formed on an n-type GaAs substrate 30. A GaAs current blocking layer 36 is formed on the layer 32 through an AlAs etching stop layer 32. The layer 36 is not added with impurity, and formed of GaAs formed by lower temperature epitaxial growth than normal growing temperature. Thus, the layer 36 has higher resistance than of the GaAs layer formed by epitaxial growth at a normal growing temperature. When a voltage is applied to a semiconductor laser the high resistance GaAs layer is used as the layer 36, and hence a current efficiently flows only to an inner active layer 44 in a groove 38. Accordingly, this laser can be operated in high efficiency with a low threshold value.
