    摘要： A laser machining device 1 includes a laser light source 10, a spatial light modulator 20, a controller 22, a converging optical system 30, and a shielding member 40. The phase-modulating spatial light modulator 20 inputs a laser beam outputted from the laser light source 10, displays a hologram modulating a phase of the laser beam at each of a plurality of pixels arranged two-dimensionally, and outputs the phase-modulated laser beam. The controller 22 causes the spatial light modulator 20 to display a plurality of holograms sequentially, lets the converging optical system 30 converge the laser beam outputted from the spatial light modulator 20 at converging positions having a fixed number of M, selectively places N converging positions out of the M converging positions into a machining region 91, and machines an object to be machined 90.

    摘要： Bags having increased blocking resistance properties are formed of a film composed of a resin blend of a polyethylene (PE) resin and a polybutylene terephthalate (PBT) resin having an intrinsic viscosity or 0.7 of more. Preferably, the film is a multi-layer structure formed via coextrusion inflation molding techniques having inner and outer layers laminated to one another. The inner layer is a polyolefin, while the outer layer is composed of a PE/PBT blend, in which the PBT is present in an amount of between 5 to 30 wt. % based on the total weight of the resin composition and has a melt index of 0.7 or more. The thickness ratio of the internal layer to the external layer is preferably between 95/5 to 30/70.

    摘要： The present invention relates to a reflective spatial light modulator enabling improvement of light resistance and prevention of damaging of the liquid crystal layer. The reflective spatial light modulator controls phases of the incident light and a reflected light while reflecting light made incident from a front side, and comprises a liquid crystal layer, a dielectric multilayer film, and a phase shift layer. The liquid crystal layer is filled with a liquid crystal comprised of a light modulating material, and modulates the incident light. The dielectric multilayer film reflects the incident light. The phase shift layer is disposed between the liquid crystal layer and the dielectric multilayer film to shift phases of the incident light and the reflected light at an interface of the liquid crystal layer.

    摘要： A temperature sensitive fluid type fan coupling apparatus is provided which can prevent "an accompanying rotation" phenomenon from being generated so as to reduce fan sound and improve fuel consumption. The fan coupling apparatus comprises a sealing device box including a cover and a case which is separated into an oil reserving chamber and a torque transmission chamber by a partition plate. A drive disc is fixed to a rotary shaft body and is disposed inside the torque transmission chamber to support the sealing device box. A circulating flow passage delivers oil from the torque transmission chamber to the oil reserving chamber. A valve member for opening and closing a supply hole communicating between the torque transmission chamber and the oil reserving chamber is provided so as to increase and reduce an effective contact area for the oil in the drive disc and torque transmission gap portion, thereby controlling a torque transmission to the side of the sealing device box driven by the rotary shaft body. Barrages for holding the oil, in the oil reserving chamber and not the torque transmission chamber, are provided on both sides of the supply hole, thereby preventing the "accompanying rotation" phenomenon in the driven side of the sealing device box due to the excessive oil.
