Abstract: The robot system including a 6-axis robot has a swingable arm for transferring a workpiece between first and second positions, a wrist on a distal end of the arm, that is driven to rotate around a predetermined axis, and a transfer device at the wrist. The transfer device has a link mechanism having first and second links and holding means attached to a distal end of the second link. A proximal end of the first link is attached to the wrist so as to rotate around the predetermined axis. A distal end of the first link and a proximal end of the second link are rotatably connected to each other. In accordance with a swinging motion of the arm, the first link rotates in a first rotational direction with respect to the arm and the second link rotates in a second rotational direction opposite to the first rotational direction with respect to the first link, so as to transfer the workpiece along a straight line linking the first and second positions.

Abstract: A method to substantially eliminate irritativeness caused by surface active agents contained in an aqueous composition is provided. The method employs, in the production of said composition, in combination one or more surface active agents having an anionic active group with one or more nonionic surface active agents, with a mutual ratio of said one or more surface active agents having an anionic active group to said one or more nonionic surface active agents being 1:1 to 1:6 in concentration by weight. Aqueous compositions with reduced irritativeness as well as a method of solubilization of an insoluble or scarcely soluble pharmaceutical ingredient in producing an external-use aqueous pharmaceutical preparation are also provided.

Abstract: An agent for contact lenses, comprising chloroacetamide. According to the present invention, chloroacetamide, which is the bacteriocidal component to be contained, is scarcely adsorbed not only to hard contact lenses and gas-permeable hard contact lenses, but also to soft contact lenses, and even if adsorbed, moreover, chloroacetamide is quickly released and is not accumulated on the contact lens to a greater extent. The inventive agent containing, in addition to chloroacetamide, sodium lauryl sulfate shows more superior bacteriocidal effect and cleaning effect. Therefore, the present invention provides an agent for contact lenses having superior bacteriocidal effect and cleaning effect, which can be used safely and with ease for various contact lenses inclusive of soft contact lenses.

Abstract: An electrophotographic device has a photosensitive element, an electrifier that forms a uniform electrostatic potential on the photosensitive element, and a light source for irradiating the photosensitive element to obtain an electrostatic latent image that has a reduced potential. A bias potential is applied to the photosensitive element after the latent image is formed, but before it is developed, so that the reduced potential of the latent image can be maintained at a constant level. With constant potentials existing on the photosensitive element, a printed image of high quality is obtained.
