摘要:
The object of the present invention is to provide an active energy ray-curable ink-jet printing ink, including: a coloring agent; a compound having an ethylenic double bond; and a photo-polymerization initiator, wherein the photo-polymerization initiator includes a compound represented by general formula (1): (wherein A represents any one of —O—, —CH2—, —CH(CH3)—, and —C(CH3)2—; and each of R1 and R2 independently represents a hydrogen atom, a methyl group, or a trimethylsilyl group), and an α-aminoketone-based compound and/or an acyl phosphine oxide-based compound, and 40% by mass or more of the compound represented by general formula (1) is included with respect to the total photo-polymerization initiator.

摘要:
An ultraviolet-curable white ink composition for ink jet recording is provided which has good dispersibility and good redispersibility and has excellent ejection stability, and provides excellent visibility of printed matter having a base material which forms a black or dark background. In an ultraviolet-curable ink composition for ink jet recording comprising titanium oxide, a polymeric dispersant having a basic functional group, a photopolymerizable compound and a photopolymerization initiator, the titanium oxide is surface-treated with silica and alumina and the weight of the silica, which coexists with the titanium oxide, is larger than that of the alumina.
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.

Provided a vehicle exterior lamp capable of illuminating the ground surrounding a vehicle. When returning to a predetermined position of a parking lot, a road or the like where a vehicle has been parked, a switch of a transmitter is operated. By doing so, the vehicle is illuminated in a predetermined color and a selected mode, and the vicinity of a door of the vehicle is illuminated by this light, so that the condition of the ground can be confirmed. Particularly, the color of the light, emitted from a light-emitting source, can be arbitrarily set, and the setting can be made, taking the brightness and the saving of the energy into consideration. Even if discriminating information, such as a code, is not provided between the transmitter and a receiver, the color of the illumination of the vehicle can be discriminated from that of other vehicles.
摘要:
Sensitivity of an electromagnetic ultrasonic probe for transmission-reception or for reception is maintained at a fixed level by first obtaining the relationship between the resonance frequency and the transmission-reception sensitivity in the range between the maximum and the minimum lift-offs and then electrically creating a relationship therebetween having an inverse frequency-sensitivity characteristic to said frequency-sensitivity characteristic and electrically adding said two relationships together.

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.
