Abstract: An information processing apparatus (1) included in a welding training system includes a transmittance adjuster (14) capable of adjusting a transmittance of a window of a welding helmet in virtual space in multiple grades, and a display controller (17) configured to cause a display of an HMD (2) to display a situation of a welding operation in the virtual space at an illuminance corresponding to the adjusted transmittance. The transmittance adjuster (14) adjusts the transmittance based on a skill level of a trainee determined by a skill level determination unit (13).

Abstract: Provided are a functional film capable of achieving adhesion between a hard coat layer and a functional layer as well as achieving desired optical properties, and a polarizing plate and an image display device, both of which include the above functional film. One aspect of the present invention provides a functional film including a hard coat layer containing a binder resin and plural inorganic particles, and a functional layer closely attached to the front surface of the hard coat layer, wherein the hard coat layer includes a first region including a layer zone, in which denseness of the inorganic particles is 60% or more, from the front surface to a depth of 100 nm in the hard coat layer, and a second region, in which denseness of the inorganic particles is 59% or less, below a depth of 100 nm from the front surface in the hard coat layer.

Abstract: According to one embodiment, a recording/reproducing apparatus including, a network controller configured to acquire a program or data via a network, a signal processing module configured to transmit and receive a program or data or a control signal using a bidirectional communication, and a determination module configured to determine that each of a connected apparatus and an external apparatus are an apparatus, which is capable of turning off the power according to a power-off instruction if the connected apparatus and the external apparatus accept the power-off instruction from the signal processing module when the signal processing module is connected to the external device via an apparatus connected by a bidirectional interface, and to notify the determination.
