Title: Method for removing mercury from liquid hydrocarbon
Inventor: FURUTA AKIO
IPC: C10G29/10
Filed: 1990-11-21
Abstract: PURPOSE:To effectively reduce the content of mercury in liquid hydrocarbon for a long time by contacting a liquid hydrocarbon containing a sparingly reac tive mercury compound with metallic aluminum or metallic zinc to decompose it, and extracting the produced free mercury with a specific extractant. CONSTITUTION:0.1 to 20wt.% of an alkali polysulfide represented by the formu la, (wherein M and M' each represent Na, K or ammonium, x is an integer of 2 to 99), such as sodium polysulfide, is dissolved in water to obtain an extract ant essentially consisting of an aqueous solution of the alkali polysulfide. A sparingly reactive mercury compound is decomposed into free mercury by contacting a liquid hydrocarbon containing a sparingly reactive mercury com pound with metallic aluminum or metallic zinc at 200 deg.C or above, preferably, from 200 to 250 deg.C for 10 to 120 minutes. Then, the produced free mercury is extracted with the extractant and removed.

Title: Surface polishing method
Inventor: ITO YASUSHI
IPC: B24D3/00
Filed: 1992-11-25
Abstract: PURPOSE:To polish projections on a magnetic disc surface with a high economic efficiency by using an abrasive member having an abrasive grain layer containing at least two kinds of abrasive grains different in hardness. CONSTITUTION:By using an abrasive member having an abrasive grain layer containing at least two kinds of abrasive grains different in hardness, the surface of a material to be polished is polished. At this time, an abrasive grain 1 is formed of diamond 4 and a material lower in hardness than the diamond 4 (for example, Al2O3 or SiC). The base member of the abrasive member is formed into a film, and recessed parts are formed between the mutual abrasive grains 1 on the abrasive grain surface of the abrasive member. Thus, projections on a magnetic disc surface can be polished with a high economic efficiency, and the magnetic disc surface can be highly precisely machined.

CONSTITUTION:When an IC card 10 is set to the prescribed position of a power source supplying part 12, the high frequency power is supplied from the power source supplying part 12 to the IC card 10. In the power source supplying part 12, a high frequency oscillator 18 is operated, a power source switching driver circuit 20 is controlled due to its signal, the high frequency powers in the reverse phase are supplied to respective outgoing panels PL1 and PL2, and between the outgoing panels PL1 and PL2, the high frequency electric field is prepared. Since the distribution capacity at approximately several hundreds pF exists between the outgoing panels PL1 and PL2 and incoming panels PT1 and PT2, the high frequency power is transmitted on the side of the incoming panels PT1 and PT2 by the static electric coupling. The high frequency power is rectified by a rectifying circuit 14, and made into a constant voltage by a stabilizing power source circuit 16. Thus, under the severe circumstances with much soil and dirt, the card can be sufficiently used.
