Abstract: PURPOSE:To improve mass productivity and reproducibility by using an ion implantation method in place of mesa-etching and buried epitaxial growth in order to form buried structure. CONSTITUTION:An N type Al0.45Ga0.55As clad layer 2 in 1mum thickness, a P type Al0.15Ga0.85As acstive layer 3 in 0.1mum and a P type Al0.35Ga0.65As guide layer 4 in 0.1mum are grown onto an N type GaAs substrate in an epitaxial manner in succession. An SiO2 thin-film is deposited onto the layer 4, a mask 5 is formed, Al ions are implanted in order to shape buried structure, and Zn ions are implanted in order to form internal current constriction structure. The active layer 3 and the guide layer 4 are formed to a striped shape along the mask 5 and sections except the layers 3 and 4 are changed into a P type Al0.45Ga0.55As clad layer 6 through a heat treatment process at approximately 800 deg.C. Zn can form the P type clad layer 6 at that time without approximately affecting the GaAs substrate 1 because a diffusion rate is accelerated in regions having higher Al composition rates.

Abstract: PROBLEM TO BE SOLVED: To drastically improve the decompositon efficiency of TOC(total organic carbon) by an ozone infection and UV irradiation and to produce a high quality treated water in which the TOC is remarkably reduced by executing an ozone oxidation treatment in a specified pH value. SOLUTION: Salts, an ionic and colloidal material and the TOC(total org. carbon) are removed at a RO membrane separating device 3 from the water removed a cation at a cation exchange resin column 1 and subjected to a decarboxylation treatment at a decarboxylation column 2.

Filed: 1981-11-24
Abstract: PURPOSE:To compensate the position of a reproducing head without using any extra track, by detecting the change of the phase of the reference clock signal produced from the digital signal data which is recorded by securing a difference between the width direction of the head gap and the width direction of a track. CONSTITUTION:The informations I1, I2, I3... are recorded on a magnetic track Tr which travels toward an arrow mark so that the same phase points are continuous obliquely and the reproduced by a reproducing head 1 having a gap 1a at the center. If the head 1 has a shift to the upper part as shown by the position 1', the output signal is identical with that obtained by reproducing the magnetized inverse information I3 which has a delay of phase. While the magnetized inverse information I1 having a gain of phase is reproduced if the head 1 shifts to the lower position 1''. As a result, it is possible to understand both the direction and the degree of the shift of the head 1 to a magnetic tape by detecting the phase of the output signal of the head 1. In such a way, the position can be compensated for the head 1.

Abstract: PURPOSE: To improve a yarn withdrawal apparatus and to use the same to be surely run in a wide range by setting the sine tangent of the tilting angle of a roller to be smaller than a minimum friction coefficient in the range of a yarn feeding part. CONSTITUTION: A yarn entrance route 14 and a suction device 24 are positioned almost in one common dividing line surface of a casing 5 or a tangent line surface. Compressed air is applied through air connecting parts 18 and 22 on an injector 17 and an injector nozzle 21.

CONSTITUTION:A claw 3 of a first member 1 is bended to a direction showed with an arrow, and the tips of the claw 3 and a rib 4 are engaged in a hole 5 of a second member 2. When the first member 1 is moved against the second member 2, the claw 3 is reset to the original condition with the elastic resetting force thereof at a point that a hook part 3a of the claw 3 and the tip of the rib 4 is passed through the hole 5, and the first member 1 and the second member 2 are bonded securely. Since a width (b) of the rib 4 becomes larger in order toward a root part of the rib 4, a coefficient of cross section thereof is larger than that of the claw 3, and a bending rigidity and a bending strenght are improved. Since a height h, of the rib 4 is equal to a height h2 of the claw 3 or higher than that, the clwa 3 is protected by the rib 4 to prevent damage of the claw 3.
