Abstract: A power system supervisory control apparatus, a power system supervisory control system, and a power system supervisory control method for reducing social cost and improving resilience of a power system are provided. The power system supervisory control apparatus including multiple renewable energy power supplies includes: a system influence degree evaluation section that evaluates a system influence degree when a renewable energy fluctuation or an assumed fault has an influence on the power system by using, as computation conditions, system data for obtaining a state of the power system, renewable energy fluctuation data indicative of a fluctuation of a power generation output, and assumed fault data of an assumed fault in the power system, and calculates system influence degree evaluation result data; a computation condition selection index calculation section that calculates a selection index for the computation conditions; and a condition selection section that selects the computation conditions.

Abstract: A body information acquisition device includes: a skeleton point detection unit configured to detect a skeleton point of a person included in a captured image; a body information acquisition unit configured to acquire body information of the person based on detection of the skeleton point; and an imaging state determination unit configured to determine whether an imaging state of the person reflected in the captured image corresponds to a specific imaging state specified based on a predetermined evaluation index value, in which the body information acquisition unit does not acquire the body information based on the detection of the skeleton point when the imaging state corresponds to the specific imaging state.

Abstract: This method of manufacturing an optical laminate comprising a transparent substrate, an adhesion layer, an optical functional layer, and an antifouling layer laminated in this order, includes an adhesion layer forming step of forming the adhesion layer, an optical functional layer forming step of forming the optical functional layer, a surface treatment step of treating the surface of the optical functional layer so that the rate of change in surface roughness represented by formula (1) is 1˜25%, and an antifouling layer forming step of forming the antifouling layer on the surface-treated optical functional layer; Rate of change of surface roughness (%)=((Ra2/Ra1)?1)×100 (%) Formula (1) (Formula (1), where Ra1 represents the surface roughness (Ra) of the optical functional layer before the surface thereof is treated, and Ra2 represents the surface roughness (Ra) of the optical functional layer after the surface thereof is treated.).

Abstract: This method for producing an optical laminate is a method for producing an optical laminate including a plastic film, an adhesion layer, an optical function layer, and an antifouling layer which are laminated in this order. The method includes an adhesion layer forming step of forming an adhesion layer, an optical function layer forming step of forming an optical function layer, a surface treatment step of performing glow discharge treatment of a surface of the optical function layer, and an antifouling layer forming step of forming an antifouling layer on the optical function layer which has been subjected to surface treatment. An integrated output of the glow discharge treatment is 130 W·min/m2 to 2000 W·min/m2.

Abstract: Provided is a mechanism for facilitating a teacher to review an online class content and how to proceed with the class. A collection unit collects log information from a user terminal, a classification unit classifies a class content, based on the log information, an extraction unit extracts information indicating a used content from the log information of the user terminal, and a recording unit records the information indicating a classification of the class and the information regarding the contents.

Abstract: A container fastener, with the use of which members such as a pallet, roof, sleeve, etc. are firmly fastened and fastening between the sleeve and the pallet and that between the sleeve and the roof are not unfastened, and an easily assembled and disassembled knockdown container using the fastener. A fastener, assembled by screwing a shank of a key (20) into a fastener body (10), is mounted on a sleeve (60), and the sleeve (60) is mounted on a pallet (70) with a rotation stop position of a knob of the key (20) adjusted so that the knob can pass through a connecting hole formed in the pallet (70). After that, the knob is rotated to advance the shank in the direction of the fastener body (10), the key is tightened by screw action until there is no play between the sleeve (60) and the pallet (70), and the rotation stop position of the knob is adjusted so that the knob does not fall out of the connecting hole. Thus, the sleeve (60) and the pallet (70) can be firmly fastened.

Abstract: A vibrator includes a voice coil and a vibrating member supported by first and second suspensions so as to be vibratory in the axial direction of the coil. Each of the first and second suspensions has an inner ring portion fixed to the vibrating member and an outer ring portion fixed to a casing of the vibrator. The inner and outer ring portions are connected through arcuate portions. Each arcuate portion has a first end connected to the inner ring portion and a second end connected to the outer ring portion. The arcuate portions of the first and second suspensions extend from the first end to the second end, respectively, in the same circumferential direction as seen from one side of the axial direction.

Abstract: A thin electromagnetic exciter has a flat casing including a casing body (2) and a cover (3), a stator (10) including an electromagnet having a coil wound around a yoke, and an oscillator (20) including a bar-shaped permanent magnet and a weight integrally attached thereto. The stator and the oscillator are disposed adjacently over a bottom wall portion (2c) of the casing body. The stator is secured to the casing body. The oscillator is vibratably supported relative to the casing body through resilient support members.
