Title: Substituted benzene dithiol metal complex and its production
Inventor: HIRAKO KAZUYOSHI
IPC: C07F1/08
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a novel substituted benzene thiol metal complex that is useful as a singlet oxygen quencher as well as can function as an optical information-recording medium. SOLUTION: This is a metal complex represented by formula I [R is a group of formula II or formula III (R1 is a 1-4C alkyl); M is a transition metal, preferably Cu, Co, Ni; A+ is quaternary ammonium or quaternary phosphonium group], typically 4-thiomorpholinosulfonyl-1,2-benzenedithiol nickel complex of formula IV. The metal complex of formula I is prepared, for example, by using a 1,2-dihalogenobenzene as a starting material to prepare a 3,4- dihalogenobenzenesulfonyl chloride, allowing thiomorpholine or a 4- alkylpiperidine to react with the resultant sulfonyl chloride to give a 4- substituted sulfonyl-1,2-dihalogenobenzene, substituting the halogen group with mercapto group, followed by reaction of the resultant mercaptan compound with a transition metal salt and a quaternary ammonium salt or quaternary phosphonium salt.

Abstract: PURPOSE:To provide a drain hole, which can surely release water infiltrated in an equipment further prevent infiltration of an insect to a minimum limit, in the lighting equipment without deteriorating appearance. CONSTITUTION:One end of a lower surface frame 21 is openably/closably mounted by a hinge 22 to a lower surface opening of a lamp unit 11 housed in a18. A latch receiver 23 is mounted to the other end of this lower surface frame 21 by a screw 24, and a latch 25 is provided in a side surface of the lamp unit 11 opposed to this latch receiver 23. A light permeating part 33 is left as mounted to an opening of the lower surface frame 21. A drain hole 42 for releasing water, advanced into an equipment, to the outside thereof is provided in a part which is a lower part of an edge plate part 41, vertically provided in a peripheral edge of the lower surface frame 21, and faced to a reverse side of the latch receiver 23. This drain hole 42 is not seen at all from the outside by the latch receiver 23 to prevent appearance from deteriorating. Since the latch receiver 23 serves as an obstruction for an insect to intend to advance into the drain hole 42 and also intercepting light, leaking to the outside from the drain hole 42 to induce infiltration of the insect, by the latch receiver 23, infiltration of the insect to the drain hole 42 can be prevented to a minimum limit.

Abstract: PROBLEM TO BE SOLVED: To prevent decrease of a flow flux of a separation membrane and to prevent reduction of a treated waste quantity by adding an inorganic flocculent to waste liquid containing abrasive particles to allow the abrasive particles in the waste water to flocculate, and separating the obtained aggregates through the membrane with a cross flow system, in the case that the abrasive particle-containing waste liquid discharged from a semiconductor plant, etc. is treated. SOLUTION: In a treatment of the abrasive particle-containing waste liquid, at first, the abrasive particle-containing waste liquid is introduced into a flocculating tank 1, and then an inorganic flocculent is fed into the flocculating tank 1 with an inorganic flocculent feed means 2, and is stirred and mixed with the waste liquid. The abrasive particles in the waste liquid become aggregates with a flocculating effect of the inorganic flocculent, and then the waste liquid containing the aggregates is subsequently introduced into a circulation tank 3, and is introduced into a membrane separation means 4 through a pipe 11 The waste liquid introduced into the membrane separation means 4 flows through a separation membrane 4b, and is circulated so as to return into the circulation tank 3 through a pipe 12.  In this circulation process, while the waste liquid flowing in the separation membrane 4b flows along the separation membrane 4b, a portion of it is transmitted through the separation membrane 4b and flows out outside the separation membrane 4b as transmitting liquid.
