摘要:
A lighting apparatus with LED includes a metal-made main body 90; a plurality of LED chip units 1 each including an LED chip and a pair of lead terminals 42, 43 electrically connected to electrodes of the LED chip; and a dielectric layer 80 disposed between the main body 90 and each LED chip unit 1 for making electrical insulation therebetween as well as bond the same. The circuit board 20 is formed with a plurality of windows 23 through which the individual LED chip units 1 extend respectively with the lead terminals held in electrical contact with the circuit pattern of the circuit board at the circumference of the window, each of the LED chip units being thermally coupled at its bottom face with the main body 90 through the dielectric layer 80, and the heat generated in the LED chip is conducted to the main body through the dielectric layer without passing through the circuit board.
摘要:
Zinc pyrithione and copper pyrithione are highly evaluated in the market as an antidandruff agent for shampoo, or an antifouling agent for ship bottom paint and fish-farming net, or an antibacterial/antifungal agent or preservative/mildewcide for industrial products and household articles. For enhancing the market value thereof, there has been a demand for a product that not only attains an increase in conventional antibacterial/antifungal effects but also exhibits novel bioactive effects and that achieves improvement with respect to problems and drawbacks relating to properties, such as solubility in seawater, and stability, such as thermal stability and weather resistance, of polymer materials. There is provided a novel pyrithione complex compound obtained by converting the conventional pyrithione metal salt to a complex compound with an oxide or hydroxide of metal such as zinc, copper or aluminum. As compared with the conventional pyrithione metal salt, this complex compound exhibits superior antibacterial/antifungal effects, newly realizes a hair-regrowing effect and successfully attains improvement with respect to the solubility in seawater and thermal stability/weather resistance of polymer materials.

摘要:
A recording apparatus and a recording method that can record both moving picture data and still picture data in a form reproducible by various reproducing apparatus. The moving picture data is compressed by an MPEG system by an MPEG encoder (2), formed into data for recording corresponding to a predetermined recording format by a format forming unit (3), and then recorded on a DVD (100). The still picture data is compressed by a JPEG system by a JPEG encoder (6), and recorded on the DVD (100) separately from the moving picture data. In predetermined timing, the still picture data compressed by the JPEG system and recorded on the DVD (100) is read, the still picture data is converted into I-pictures of the MPEG system by a format converting unit (7), and then the I-pictures of the MPEG system are recorded onto the DVD (100) in the predetermined format via the format forming unit (3).
摘要:
The positively chargeable toner includes a binder resin and a coloring agent, the binder resin including (a) a resin (1) capable of forming a matrix in the toner, the resin (1) being a hybrid resin of a polyester resin and a vinyl resin; and (b) a resin (2) capable of forming a domain dispersed in the matrix formed by the resin (1), the resin (2) being a vinyl resin having a positive charge functional group. This positively chargeable toner has a good evenness of chargeability and a high charging-up speed with a small proportion of a reversely charged toner upon triboelectric charging. Moreover, in a heat roller fixing method, fixing at a low temperature can be performed without using an offset inhibiting liquid.
摘要:
The nonmagnetic one-component toner is usable in a developer device including a developer roller and a blade, the blade serving to regulate a toner layer formed on the developer roller into a uniform thickness and to supply electric charges to the toner by triboelectric charging, and the nonmagnetic one-component toner includes at least a binder resin, a colorant, and an iron compound. Here, the binder resin includes a polyester resin as a main component, and the iron compound has the general formula (I) and is contained in an amount of between 0.1 parts by weight or more and less than 1.0 part by weight, based on 100 parts by weight of the binder resin.
摘要:
An industrial microbicidal/microbistatic composition which comprises (1) 4,5-dichloro-1,2-dithiol-3-one and (2) N-dodecylguanidine hydrochloride or N-dodecylguanidine acetate and a method of killing or inhibiting the growth of microbe or controlling slime formation using said composition.
摘要:
The present invention provides carboxymethylcellulose or a salt thereof that can prevent defects such as streaks and pinholes from occurring in the obtained electrode when it is used as a binder for an electrode of a nonaqueous electrolyte secondary battery. The present invention provides carboxymethylcellulose or a salt thereof of which ratio of a dry mass A to a dry mass B is less than 50 ppm when 2 liters of a 0.3 mass % aqueous solution of the dry mass B of the carboxymethylcellulose or a salt thereof is prepared, the entire amount of the aqueous solution is filtrated through a 250-mesh filter under a reduced pressure of −200 mmHg, and the dry mass A of a residue on the filter is measured after filtration. The applications of the carboxymethylcellulose or a salt thereof are also provided.
