Abstract: A lighting device includes a main body including a belt-shaped portion mounted along a circumferential direction of a head of a wearer, a storage case provided in the main body and positioned in a forehead region of the wearer when the lighting device is mounted on the wearer, and a light source unit that is incorporated in the storage case and includes a light emitting diode (LED) substrate on which a plurality of LED light sources is mounted. The light source unit includes a condensing lens for condensing light emitted from the plurality of LED light sources, a reflecting mirror for deflecting light emitted from the condensing lens and reflecting the light toward an affected part of a patient, and a radiator plate that radiates heat generated from the LED substrate and extends from a forehead region toward a parietal region of the wearer.

Abstract: [Problem] To provide a novel antimicrobial agent that has excellent antimicrobial activity and which is prepared from an ester composed of propanediol and a ?-hydroxycarboxylic acid. [Solution] An antimicrobial agent which is prepared from a propanediol mono-?-hydroxycarboxylic acid ester expressed by the following formula (1) or formula (2) (wherein R1 and R2 are both branched or unbranched, and saturated or unsaturated alkyl groups having 5 to 9 carbon atoms).

Abstract: A novel antiseptic agent composition which has a wide antimicrobial spectrum and excellent antiseptic properties is provided. An antiseptic agent composition A contains a glycerin hydroxy fatty acid monoester that is an ester of glycerin and a hydroxy fatty acid having 8 to 18 carbon atoms, and a specific antiseptic agent such as an alkanediol. An antiseptic agent composition B contains the glycerin hydroxy fatty acid monoester and an aromatic antiseptic agent. An antiseptic agent composition C contains the glycerin hydroxy fatty acid monoester and a chelating agent.

Abstract: A novel antimicrobial agent which has a high degree of safety, an excellent compounding property and strong antimicrobial activity is provided. The antimicrobial agent is characterized by containing ricinoleic acid monoglyceride or diglycerine ricinoleic acid monoester as an active ingredient. The antimicrobial agent of the present invention is suitable as a compounding component of an antimicrobial object selected from a food product, a food packaging material, tableware, a perfume cosmetic, a cosmetic, an external preparation for skin, a skin washing agent, a disinfectant, a lotion for external use, an agent for hair, a wiping sterilization agent, a pharmaceutical, a quasi drug and a hygiene material for the oral cavity.

Abstract: A method and an apparatus for bending pipes by clamping one end of the pipe between a formed roll and a rotary base and by turning the rotary base so that the pipe may be bent along the outer periphery of the formed roll. A mandrel supported by a mandrel bar is arranged inside the pipe at a position corresponding to a position slightly behind where the pipe is clamped between the formed roll and the rotary base. The rear end of the mandrel bar is held in place by a pressurizing device so that the mandrel can be held fixed at said predetermined position inside the pipe. At the same time, a vibrating device attached to the mandrel bar causes the mandrel to continuously reciprocate in the axial direction of said mandrel bar, whereby flattening of the pipe which occurs when the pipe is bent along the outer periphery of the formed roll can be corrected by the reciprocation of the mandrel. As a result, the radius of curvature R of the pipe can be made smaller than R=3D, where D is the diameter of the pipe.

Abstract: An apparatus for manufacturing a multielement sintered material is provided, more particularly an appartus of the automated type which weighs and mixes predetermined amounts of powdery elements, molds the mixed elements and then sinters them.
