Abstract: The present invention enables shortening the time required for resuming communication in a protection method that uses a backup path in an optical communication system that includes a master station device and multiple slave station devices. The slave station devices are connected to a loop path in parallel. The communication paths between the master station device and the slave station devices include a normal path and a backup path. The master station device executes communication control processing with respect to the slave station devices based on the RTTs. A first slave station device is a slave station device that cannot perform communication via the normal path. If the first slave station device is detected, the master station device calculates a first backup path for the first slave station device based on a first RTT between the master station device and the loop path, a loop RTT required for one full lap on the loop path, and the first normal path RTT for the first slave station device.

Abstract: Provided is an estimation device that estimates a response at a position of a floating structure where a sensor detecting a structural response is not installed. The estimation device acquires a strain response spectrum at an installation position at which a strain sensor is installed on a floating structure, the strain response spectrum being calculated based on the strain sensor, a wave spectrum, and strain response functions at the installation position and at a non-installation position of the strain sensor, calculates a correction amount based on a predetermined formula expressing a relationship among the strain response spectrum, the wave spectrum, and the strain response functions, and adds the correction amount to a theoretical value of the strain response spectrum calculated from the strain response function and the wave spectrum at the non-installation position of the strain sensor to calculate the strain response spectrum at the non-installation position.

Abstract: In a method of manufacturing a front pillar, a resin layer is formed by discharging a transparent resin from first nozzles of a 3D printer and discharging a supporting material from second nozzles of the 3D printer, while moving the first nozzles and the second nozzles in a direction corresponding to a length direction of a front pillar. Afterwards, the first nozzles and the second nozzles are moved relatively in a direction corresponding to a transverse direction of the front pillar and in a direction of moving away from the resin layer. By repeating the forming of the resin layer and the relative moving of the first nozzles and the second nozzles, the resin layers are layered in the direction corresponding to the transverse direction of the front pillar such that the front pillar is manufactured.

Abstract: In a battery frame, an upper panel is made of carbon fiber reinforced plastic, and first reinforcements are made of sheet metal. Head portions of rivets are disposed at the upper panel side, and a diameter dimension of the head portions is set larger than that of caulking portions of the rivets. This enables a contact surface area between the rivets and the upper panel to be larger than in cases in which the caulking portions are disposed at the upper panel side. This enables peripheral edge portions of first joint holes in the upper panel to be supported by the head portions of the rivets over a large surface area. The peripheral edge portions of the first joint holes in the upper panel are thereby suppressed from breaking and the like.
