Title: Method for refining indium
Inventor: YUKINOBE MASAYA
IPC: C22B58/00
Filed: 1987-12-14
Abstract: PURPOSE:To manufacture a high-purity In of semiconductor grade by allowing metallic In to react with Cl gas, carrying out distillation refining, immersing the obtained refined InCl in pure water to carry out disproportioning, separating the resulting metallic In, and subjecting this metallic In to melting in a hydrogen air flow and then to solidification by cooling. CONSTITUTION:A Cl gas is blown into metallic In of about 99.99% purity at a temp. in the vicinity of the melting point (220 deg.C) of InCl to form InCl, and blowing is discontinued at the stage where metallic In remains. At this time, the initial distillate (about 5-30% of the whole distillate) is separated. Subsequently, the refined InCl is immersed in pure water and formed into metallic In and InCl3 by means of disproportionation at <=about 60 deg.C, and the metallic In is separated from the aqueous solution of InCl3. The separated spongy metallic In is sufficiently washed with pure water, melted in a hydrogen air flow or in vacuum, and solidified by cooling so as to be formed into an ingot. By this method, the high-purity metallic In of >=about 99.99999% purity can be obtained.

Abstract: PURPOSE: To obtain a semiconductor laser light sorce whose light axis and the like can be adjusted easily and whose optical characteristics are hardly varied by the variation of an external environment by a method wherein 1st and 2nd fixing tables to which a semiconductor laser and an uneven interval diffraction lattice are attached are provided and their linear expansion coefficients are selected properly to adjust the distance between the semiconductor laser and the uneven interval diffraction lattice automatically so as to have a certain relation with a varying focul distance.  
     CONSTITUTION: Fixing tables 3 and 4 are fixed to a stem 6. The fixing table 3 is composed of an attached part 31 fixed to the stem 6 and a horizontal part 32 to which a semiconductor laser 1 is fixed. The fixing table 4 is composed of a horizontal part 41 fixed to the stem 6 and, its tip part 42 to which a lens 2 is fixed. An optical system containing the semiconductor laser 1 and the lens 2 is housed in a cap 5 to reduce the influence of an external environment. At that time, the fluctuation of the focal distance of the lens caused by the variation of the oscillation wavelength of the laser created by the temperature variation and the fluctuation of the focal distance caused by the thermal expansion and contraction of the lens material cancel each other but not completely. Then, when the temperature rises, the horizontal part 32 is made to show a larger thermal expansion than the horizontal part 41 and the distance between the semiconductor laser 1 and the lens 2 is reduced to follow the focal distance varied by the temperature.

Abstract: PURPOSE:To obtain the high-quality joint of a thin pipe and pipe joint by inserting the front end of pipe joint bored with a lead hole of the diameter smaller than the diameter of the thin pipe into the thin pipe, executing welding to the both and working the bore of the pipe joint so as to be equal to the bore of the thin pipe. CONSTITUTION:The front end 2b of the pipe joint 2 which is bored with the lead hole 2a of the diameter smaller than the inside diameter of the thin pipe 1 and has the size to allow the insertion of the outside diameter of the front end 2b into the thin pipe 1 is inserted into the thin pipe 1. The front end of the pipe joint 2 is formed to the thickness larger than the thickness of the thin pipe 1. The pipe wall part at the front end of the pipe joint 2, therefore, acts like a backing strip at the time of welding the thin pipe 1 and the pipe joint 2. The generation of a hole by burn-through is thus prevented and the sure welding is executed. The hatched part shown in the figure is removed by machining, etc., with the lead hole 2a of the pipe joint 2 as a guide and the bore of the joint 2 is thereby equaled to the bore of the thin pipe 1, by which the welding is completed.

Abstract: PURPOSE:To grasp the constitution of a packed card by transmitting the code read address information, the card name rough sorting code information, and the multi-identification address information via a master card and at the same time returning the card name fine sorting code information and the multi-sheet code information via a slave card respectively. CONSTITUTION:A master card produces the code read address information, the card name rough sorting code information, and the multi-identification address information as the address signals so as to check the constitution of a slave card via a check address signal production/transmission means. These address signals are sent to the slave card via a bus line. Then an answer data signal reception/identification means receives the card name fine sorting code information and the multi-sheet code information sent back from the slave card as the data signals via a bus line based on a check address signal and then identifies the type and the name of the slave card as well as the present number of cards of the same type based on a data signal. Thus it is possible to grasp the constitution of a packed card without changing a standard bus.
