An electrophotographic magenta toner which comprises a binder resin and a colorant comprising (a) 0.5 to 15 parts by weight of C.I. Pigment Red 57:1 and (b) 0.5 to 15 parts by weight of C.I. Pigment Red 81 or C.I. Pigment Red 122, per 100 parts by weight of the toner. A magenta developer comprising the magenta toner, and a full color image forming method using the magenta toner or developer are also disclosed.
摘要:
A switching power supply wherein an inductor device is connected to the center tap of a primary winding of a transformer with a switching device provided to apply high frequency signals to the transformer concurrently with a rectified smoothed input signal applied to the primary winding concurrently by another inductor device so that the secondary winding of the transformer produces a DC output signal which is free of harmonic current and whereby the switching power supply power factor is improved.

An electrostatic-image developer which comprises: (i) a toner comprising: (a) toner particles containing carbon black in an amount of from 6 to 8% by weight based on the weight of the toner particles and having a volume-average particle diameter of from 3 to 9 .mu.m; and (b) an external additive; and (ii) a resin-coated carrier having a volume resistivity of from 10.sup.7 to 10.sup.11 .OMEGA..multidot.cm in an electric field of 10.sup.3.8 V/cm and an average particle diameter of from 30 to 60 .mu.m. Also disclosed are a process for forming a black image and a process for forming a full-color image each using the electrostatic-image developer.
摘要:
A percutaneously absorbable preparation which contains norethisterone, estradiol or ester thereof, each of which is highly absorbable percutaneously, can readily be stuck to the skin, and is lowly skin irritating. It is prepared by applying a pressure-sentitive adhesive layer comprising a drug and a pressure-sensitive adhesive to one side of a support. The drug comprises at least one member selected from among norethisterone, estradiol and pharmacologically acceptable esters thereof, while the adhesive comprises a copolymer composed of 20-55 mol. % of vinylpyrrolidone and 80-45 mol. % of alkyl (C.sub.4 -C.sub.18) (meth)acrylate. The adhesive layer further contains a sorbifacient comprising 0.1-10 wt. % of at least one member selected from among dicarboxylic acids, hydroxy carboxylic acids, plyoxyethylene alkyl ethers and amide compounds and 5-40 wt. %, both based on the adhesive layer, of a higher fatty acid ester prepared from a C.sub.10 -C.sub.18 fatty acid and a C.sub.1 -C.sub.20 alcohol and also contains a cohesive force improver.
摘要:
A maleimide derivative having the formula (I): ##STR1## wherein R.sub.1 represents a lower alkyl group having 1 to 4 carbon atoms, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 independently represent a hydrogen atom, a lower alkyl group having 1 to 4 carbon atoms, a phenyl group which may be substituted, or an aralkyl group having 7 to 10 carbon atoms, and X.sub.1 and X.sub.2 independently represent a hydrogen atom or a halogen atom, and a production process thereof as well as a agricultural and horticultural fungicide containing, as an active ingredient, the maleimide derivative.
摘要:
The present invention constitutes a construction joint of a bicycle frame comprising a rear dropout body having projecting portions decreasing in taper as they extend away from the body, each projecting portion defining an elongated screw hole extending along a longitudinal axis of the projecting portion, the projecting portion defining a slit extending on both sides of the screw hole; chainstay and seat stay pipes, each surrounding a projecting portion, the chainstay and seat stay pipes having gradually decreasing diameters towards the base end of the projecting portions; a screw or wedge inserted into the screw hole to enlarge the outside circumference of the projecting portion until it fixedly contacts the interior of the chainstay and seat stay pipes; and an adhesive agent spread around the projecting portion of the rear dropout body and inside the chainstay and seat stay pipes.
摘要:
A bicycle frame of the present invention is formed as follows.First, the worker puts and bonds a pipe made by fibre reinforced plastics around a cylindrical projecting part of a lug made by thin wall thickness light alloy.Next, the worker covers a joining part of the said projecting part of a lug and pipe made by fibrer reinforced plastics by sheet molding compound, (hereinafter it is called "SMC").Last, the joining part of the projecting part of a lug and the pipe covered by said SMC is put in a molds for compression molding.As the SMC consists of required quantity of plastics and chopped fibre same as filament comprised in the pipe made by fibre reinforced plastics, bonding of the pipe made by fibre reinforced plastics and said SMC is very good. Consequently, the joining strength of the pipe and lug is very strong in the present invention.
