Title: Insolubilization treeatment of selenium contaminated soil
Inventor: KAWACHI TAKESHI
IPC: B09C1/02
Filed: 1995-03-16
Abstract: PURPOSE: To prevent or lessen the elution of selenium from soil contaminated with selenium by adjusting the pH of contaminated soil contg. the selenium to a specific value. CONSTITUTION: This insolubilization treatment method for the selenium contaminated soil comprises first putting a pH controller supplied from a tank 2 into a mixer 1 and stirring and mixing this controller. Controllers prepd. by properly diluting, for example, hydrochloric acid or sulfuric acid at need are used as the pH controller. Next, this soln. is put together with the contaminated soil contg. the selenium into the soil mixer 3 and is sufficiently stirred and mixed to adjust pH which is an index to indicate the concn. of the hydrogen ions in the soil to <=6, more preferably to <=5.5. As a result, the elution amt. of the selenium from the polluted soil is lessened to about 1/4 the elution rate from the original contaminated soil.  The elution rate of the selenium from the original contaminated soil is decreased to <=1/10 and is thus completely suppressed particularly if the pH is adjusted to <=6 by adding an iron oxide to the contaminated soil.

IPC: G01N29/04
Filed: 1995-04-11
Abstract: PURPOSE: To obtain an ultrasonic probe by which a flaws tilted at various angles can be detected surely with a simple and inexpensive constitution and by installing a switch by which a vibrator whose angle of beam spread of ultrasonic waves is at a specific angle or higher and an ordinary vibrator are changed over. CONSTITUTION: In an ultrasonic probe 1, a first vibrator 3 whose angle of beam spreas of ultrasonic waves is at 5 deg. or higher and second ordinary vibrators 4 on both sides of it are fixed, by an adhesive, to a slope 22 which is tilted with reference to the bottom face 4 of a wedge 2. An ultrasonic flaw detector 7 is connected via a switch 5 so as to change over the vibrators 3, 4. Since the angle of beam spread of the ultrasonic waves is wide at 5 deg. or higher by the vibrator 3, the ultrasonic waves are incident perpendicularly to a flaw even when the flaw is tilted, and reflected waves are returned to the ultrasonic probe 1. As a result, the flaw which is tilted at various angles can be detected by one probe 1.  After the flaw has been detected, the vibrators 4 are changed over by the switch 5, the directivity of the ultrasonic waves is made sharp so as to detect the flaw, and the flaw can be evaluated.

Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To generate an object program in a state in which capacity is small and processing is fast when a language processor converts a source program into the object program. SOLUTION: When a source program 1 is converted into an object program 4, a function detecting means 12 analyzes the program 1 and separately detects an array of plural functions, a call detecting means 15 detects the call relation of plural functions, an array changing means 16 generates an array of functions where number of calls for a short distance becomes a large number, and an array changing means 17 changes function orders to the array. Because the program 4 is generated in a state in which the number of calls for short distance becomes a large number through the change of a function array, it is generated in a state which capacity is small and processing is fast.

IPC: H01L29/737
Filed: 1992-04-07
Abstract: PURPOSE:To obtain a constant C concentration by using an Al compound for an Al source of a C doped p-type epitaxial Al epitaxial AlGaAs layer where Al and C are not joined with each other in the compound. CONSTITUTION:When manufacturing a C doped p type epitaxial layer based on a metal organic chemical vapor deposition (MOCVD) process, an Al compound where Al is not directly joined with C is used for an Al source. For such Al compounds, there are cited trimethyl amine alane (H3AlN (CH3) 3) and dimethyl amine alane (H3AlN (CH3) 2C2H5) and the like for example. Since these compounds with amine and alane are thermal decomposed with ease, they are thermally decomposed in an MOCVD device and alane (AlH3) is generated when they are supplied to the device as the Al source. This alane functions as the Al source in the MOCVD process. This construction makes it possible to form a p-type AlxGa1-xAs layer having a constant concentration, and an Al composition inclination.

Title: Semiconductor laser
Inventor: FURUSE TAKAO
IPC: H01S5/00
Filed: 1987-04-07
Abstract: PURPOSE:To provide semiconductor laser which is capable of providing multi- axis mode oscillation state with good repetition and excellent in its noise characteristic for returning beams, by forming a structure to make a current flow unevenly in the laser resonator direction of an active layer which serves as a luminous region. CONSTITUTION:An n-type GaAs layer 2 of about 1 mum in thickness is formed on a p-type GaAs substrate 1. Next, a photoresist process and a chemical etching process, which are normally used, are used to form a striped groove 12 of about 4mum in width and about 0.1mum in thickness of its bottom part. Thereupon, the n-type GaAs layer 2 is made to remain about 0.1mum in thickness on the bottom part of the striped groove which is formed on the n-type GaAs layer 2. Thus, pnp junction composed of the p-type GaAs substrate 1, the n-type GaAs layer 2, and a p-type Al0.4Ga0.6As layer 3 is formed on the bottom part of the groove. Since this method allows this bottom part of the groove to vary slightly in its thickness in the direction of a resonator axis, a current injected in an active layer 4 flows unevenly in the direction of the resonator axis, and a laser oscillation axis mode is formed into a multi-type, and a noise characteristic for returning beams can be improved accordingly.
