摘要:
An ink composition for ultraviolet curable ink-jet recording including carbon black, a photopolymerizable compound and a photopolymerization initiator, comprising at least one selected from the group consisting of non-metallic phthalocyanine sulfonic acids, metal phthalocyanine sulfonic acids in which the central metal is Cu, Fe, Ni, Co, or Ti, and metal salts thereof, and a polymer dispersant containing a basic functional group. The photopolymerizable compound may dissolve the polymer dispersant.

A light source device has a light shielding member having an aperture, a light source arranged on one side of the light shielding member, and a converging member arranged relatively with respect to the light source and the light source to thereby converge light emitted from the light source in the aperture or in a vicinity of the aperture. Another type of light source device has a single light source, and a converging member for converging light from the light source to thereby distribute the light to at least two points. Still another type of light source device has a light source, and a reflecting mirror arranged to enclose a side of a light emission direction of the light source, the reflecting mirror reflecting light emitted from the light source in a direction except the light source so that the light is radiated outside.

A bottle with a hanging tool detachably provided. The hanging tool comprises a flat and long connection portion extending sideways from the neck portion and having a length shorter than an outer diameter of the bottom of the bottle, and a separately molded wide annular handle portion. The connection portion is provided at its intermediate portion with a narrow portion crossing the connection portion transversely to reduce a thickness thereof, thereby making the connection portion vertically bendable at the narrow portion, a free end of the connection portion and the handle portion are formed at their predetermined locations with joint portions comprising a pair of engagement means, and the handle portion is detachable attached to the connection portion. Thereby an injection mold for molding a preform can be simple in structure and is suppressed from being enlarged.

A pyrrolo[2,3-d]pyrimidine derivative having the general formula [I] ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, Y and Z have the same definitions as those given in the description, a pharmaceutically acceptable acid addition salt thereof, and a pharmaceutical preparation comprising the same, are provided.
摘要:
Effective disinfection and washing of immobilized lactase from Aspergillus oryzae is carried out after a period of hydrolyzing lactose by treatment of the immobilized lactase with aqueous solutions of pH's 2 to 4 and 6 to 8.7, one or both of which contain a disinfectant. The solution having a pH of 6 to 8.7 may be a phosphate buffered solution. The lactase may be immobilized on a high polymer compound by covalent linkage. The immobilized lactase has outstanding resistance to chemicals and wide pH stability so that decrease of lactase activity is minimized.

A photo-catalyzer for deodorizing, cleaning, sterilizing, and water purifying operations includes a substrate, a titanium dioxide film disposed on the substrate and functioning as a photo-catalyst, and a light-emitting diode disposed adjacent to the titanium dioxide film and producing ultraviolet light having a wavelength from 360 to 400 nm onto the titanium dioxide film. The photo-catalyzer can be used in places where there is no sunlight because it is optionally provided with a light-emitting diode. The light-emitting diode does not require a large installation space because it is an extremely small light-emitting device. Hence, the photo-catalyzer has a compact structure and can be used easily anywhere, including small places. The substrate can be fabricated into a variety of useful appliances to take advantage of the strong oxidizing properties of the photo-catalyzer. Devices comprising a photo-catalyzer may be used for deodorizing, destroying or repelling micro-organisms, and including undertaking air or water purification.
