Title: Electrolyzing method for removing arsenic
Inventor: ABE TATSUICHIRO
IPC: C02F1/461
Filed: 1984-07-10
Abstract: PURPOSE:To remove efficiently impurities from a copper electrolytic soln. used in the electrolytic refining of copper by allowing SO2 to be absorbed in the electrolytic soln. and purifying the soln. by electrolysis in an electrolytic cell for removing arsenic. CONSTITUTION:When an electrolytic soln. drawn from an electrolytic cell for electrolytically refining copper is purified in an electrolytic cell for removing arsenic, SO2 is allowed to be absorbed in the electrolytic soln. to reduce most of quinquevlent impurities to tervalent ones before the soln. is introduced into the electrolytic cell for removing arsenic. The amount of SO2 absorbed is regulated to about 0.5-6.5g/l. Thus, electrolysis for removing arsenic is carried out rapidly and efficiently.

Title: Laser diode
Inventor: NAKAJIMA YASUO
IPC: H01S5/00
Filed: 1986-06-18
Abstract: PURPOSE:To implement a module readily, by sealing a semiconductor in an airtight manner, providing an optical isolator in a airtight sealing cap or in a window, and forming a unitary body of the semiconductor laser and the optical isolator. CONSTITUTION:Light, which is emitted from a semiconductor laser 6, is taken out of an optical isolator 5 of a cap 7. The polarization plane of the light emitted from the semiconductor laser 6 is rotated by 45 degrees when the light passes a polarizer 3 and a Faraday rotator 2, which can rotate the plane of polarization of the light by 45 degrees. The light is sent to the outside through an analyzer 4. Meanwhile, the polarization plane of the reflected returning light from other optical parts such as optical fiber is further rotated by 45 degrees, when the light passes the Faraday rotator 2. Therefore the reflected returning light is turned by 90 degrees with respect to the light emitted from the semiconductor laser 6. Thus the reflected returning light is blocked by the polarizer 3. The optical isolator 5 and the cap 7 form a unitary body. The semiconductor laser 6 is sealed in an airtight manner.
