Abstract: The present invention is a method for manufacturing an optical fiber which includes a resin coating step in which a resin is supplied to a resin coating section via piping, and a glass fiber is passed through the resin coating section such that the resin is coated on the outer circumference of the glass fiber. In the resin coating step, the temperature of the resin inside the piping is measured, and a heating unit provided on the outer circumference of at least some of the piping is controlled such that the temperature of the resin inside the piping reaches a set target temperature; and a viscometer is disposed in between the resin coating section and the piping on which the heating unit is provided, and the set value of the target temperature is adjusted such that the viscosity of the resin measured by the viscometer reaches a target viscosity.

Abstract: The present invention bonds a label to an adherend with a heat-sensitive adhesive layer disposed therebetween, by sufficiently activating the heat-sensitive adhesive layer. Prepared is a label which comprises a label base and a heat-sensitive adhesive layer disposed on the back surface of the label base, wherein an ultraviolet-absorbing heating agent is contained in an area of the label base which at least includes the disposed heat-sensitive adhesive layer and/or in the heat-sensitive adhesive layer. Before or after the label is applied to an adherend, irradiation with ultraviolet is conducted to activate the heat-sensitive adhesive layer.

Abstract: Providing a system which can exhibit a desired effect of improving hydrophilicity of a contact lens without causing adverse influences on sense of use of the contact lens and a cleaning effect, and which can effectively prevent adhesion of lipid stain. Also providing a packaging solution for the contact lens which can effectively suppress or prevent reduction of its viscosity with time even when the packaging solution is sterilized by heating. The contact lens is immersed in an aqueous solution which contains a low-molecular weight hyaluronic acid having a molecular weight of not higher than 80,000, or a salt or derivative thereof, and which has a pH of 6.0-8.0 and an osmotic pressure of 220-380 mOsm.

Abstract: A vehicle seat is provided with: a rotation lock mechanism for inhibiting or permitting rotation of the both support arms placed at a fixed position relative to base frames and a support arm operation mechanism for actuating the rotation lock mechanism by tilting of a backrest. In the vehicle seat, when the backrest is tilted forward beyond a maximum forward adjustment angle of a reclining angle range, the rotation of the both support arms from the fixed position is permitted. When the backrest is tilted further backward than the maximum forward adjustment angle, the rotation of the both support arms from the fixed position is inhibited.
