Title: Method for removing impurity in copper or copper alloy scrap
IPC: C22B15/14
Filed: 1992-03-12
Abstract: PURPOSE:To reproduce Cu scrap contg. impurities, such as S and Pb to high- purity Cu by melting the Cu scrap and slagging the S as a compd. with Al and the Pb as a multi component oxide with Mn or Fe. CONSTITUTION:The Cu scrap contg. the S from press oil sticking to a press at the time of press forming of Cu and the Pb by the solder at the time of soldering is melted and thereafter, a deoxidizing agent, such as Si, is added thereto to deoxidize the Cu scrap and to decrease the concn. of the O2 in the melt to <=50ppm. Al of >=0.005wt.% is then added to the melt to convert the S in the melt to Al2O3. The Al2O3 is adsorbed to a flux consisting of charcoal or borax, cryolite and NaCl and is thereby slagged. The slag is floated and removed and thereafter the melt is subjected to a deoxidation treatment. If the scrap contains the Pb, the S is removed as Al2O3 and thereafter, MnO2 or Fe2O3 is added to the melt to adjust the concn. of the O2 in the melt to >=1000ppm and to adsorb the Pb as the multi component oxide with the Mn or Fe on an adsorbent, such as charcoal, by which the Pb is slagged and removed. The melt is then subjected to the deoxidation treatment, by which the Cu scrap is regenerated to the high-purity Cu.

Title: Delivery control compressor
Inventor: TAGUCHI TATSUHISA
IPC: F04C14/26
Filed: 1986-03-12
Abstract: PURPOSE:To make wide-range, continuous delivery change possible by controlling a bypass hole by making a spring work by using differential pressures between inside pressures of a high pressure introduction pipe arranged in a space on the side of a slider in the direction of the rotation of a rotor and inside pressures of a low pressure introduction pipe arranged in a space on the side of the slider opposite to the direction of the rotation of the rotor. CONSTITUTION:As discharge pressures increase and suction pressures decrease, a side plate 5 having a bypass hole 6 extending in an arc-shape in the direction of rotation of a rotor 2 is moved by relative relationship between a drive force due to pressure differential between pressures in a high pressure introduction pipe 11a for introducing high pressures in a compressor to a space 11 on the side of rotation of a rotor and pressures in a low pressure introduction pipe 12a for introducing low pressures to a space 12 on the side opposite to the direction of rotation of the rotor and a force of a spring 14 arranged in a space 12 on the side opposite to the direction of rotation of the rotor to make a span of a bypass hole 6 shorter and to make it possible to operate with a large discharge rate. Then in the case opposite to the above, it is made possible to move on continuously to a smaller discharge rate with longer span of the bypass hole 6. Thus, it is made possible to change the discharge rate continuously over a wide range and to reduce the size of an equipment.
