Abstract: Disclosed is a semiconductor device manufacturing method, including a preparation step of preparing a laminated body in which a supporting member, a temporary fixation material layer that generates heat upon absorbing light, and a semiconductor member are laminated in this order, and a separation step of irradiating the temporary fixation material layer in the laminated body with incoherent light and thereby separating the semiconductor member from the supporting member.

Abstract: An object is to provide a polarizing lens in which a polarizing function differs depending on the region of the surface of the lens. A polarizing lens that includes a polarizing layer on a lens base material and that includes a region in the surface of the lens in which the degree of polarization caused by the polarizing layer continuously differs or a region in the surface of the lens in which the film thickness of the polarizing layer continuously differs.

Abstract: Provided is a spectacle lens endowed with high luminous transmittance as well as adequate polarizing function. A method for manufacturing a spectacle lens, comprising forming a polarizing layer by applying a coating liquid containing 0.04% by mass to 1.5% by mass of a dichroic pigment by a spin coating method at a speed of 200 rpm to 600 rpm on a rubbing-treated surface.

Abstract: Provision of a spectacle lens provided with a satisfactory degree of polarization from the perspective of ability to suppress glare, as well as with high luminous transmittance, the spectacle lens having a high degree of freedom of frame selection relative to the prior art, and enabling the reduction of the turnaround time from order receipt to delivery; and spectacles. A spectacle lens having a lens substrate and a dichroic pigment coating layer directly on the lens substrate or on the lens substrate via another layer, the spectacle lens having a degree of polarization of 10% to 60% and a luminous transmittance of more than 75%, and spectacles having the spectacle lens and a frame to which the spectacle lens is mounted.

Abstract: To provide a dichroic dye-containing liquid that is capable of preventing haze without decrease of adhesiveness of a polarizing layer, and a polarizer. The dichroic dye-containing liquid contains (A) a dichroic dye and (B) a toughness-imparting agent, in which the dichroic dye (A) and the toughness-imparting agent (B) are dispersed or dissolved in an aqueous medium, and a solid content X (% by mass) of the toughness-imparting agent (B) based on the dichroic dye-containing liquid and a 100% modulus Y (MPa) of the toughness-imparting agent (B) satisfy relationships represented by the following expressions (1) and (2): 0.01?X?1.0??(1) Y?0.14X?1.5??(2) and the polarizer contains a substrate having provided sequentially thereon an orientation layer and a polarizing layer, in which the polarizing layer containing a dichroic dye that is oriented and accumulated by using the dichroic dye-containing liquid.

Abstract: An ultrasonic motor is provided having a first oscillating member and a second oscillating member. The first oscillating member vibrates with a given wavelength. The second oscillating member is separately provided to the first oscillating member, and vibrates with the given wavelength. An annulus is formed by the first oscillating member and the second oscillating member. Part of the first oscillating member overlaps with part of the second oscillating member in a radial direction of the annulus for one quarter of the given wavelength in a circumferential direction of the annulus.

Abstract: A decomposition inhibitor for hydrochlorofluorocarbons and hydrofluorocarbons (HCFCs/HFCs) which comprises at least one member of the class consisting of organic acid-amine mixtures, fluorine-free halogenated hydrocarbons, carboxylic acid esters, nitrile compounds, carbonyl compounds and halogenated nitro compounds. A method of inhibiting the decomposition of HCFCs/HFCs which comprises using the decomposition inhibitor mentioned above.In the field of polyurethane foam manufacture using HCFCs/HFCs as blowing agents, the effect of inhibiting the decomposition of HCFCs/HFCs can be produced over a long period of time covering the storage of raw materials, the foam manufacturing process and the use of foamed products.
