Abstract: The present embodiment is a tank having a liner and a first protective layer disposed on an outer peripheral surface of the liner and configured such that a resin-impregnated fiber bundle including a reinforcing fiber bundle and a first matrix resin is wound around the liner, wherein the resin-impregnated fiber bundle has a folded portion fixed in a bent state at a winding end portion of the resin-impregnated. fiber bundle.

Abstract: The present embodiment is a method of recycling reinforcing fibers, the method comprising: providing a tank having at least a first protective layer disposed on an outer peripheral surface of a liner and a liner, the first protective layer being configured such that a resin-impregnated fiber bundle including a reinforcing fiber bundle and a first matrix resin is wound around the liner; and a second protective layer formed of the first matrix resin on the first protective layer; removing a portion of the second protective layer to expose a winding end portion of the resin-impregnated fiber bundle; peeling the exposed winding end portion; and pulling the peeled winding end portion to draw out the resin-impregnated fiber bundle.

Abstract: Provided is a method of recycling carbon fibers that allows obtaining continuous carbon fibers. The present embodiment is a method of recycling carbon fibers that includes preparing a carbon fiber reinforced plastic molded product including carbon fiber reinforced plastic containing carbon fibers and a resin and drawing the carbon fiber reinforced plastic while performing a heating treatment on the carbon fiber reinforced plastic molded product. A temperature of the heating treatment is equal to or above a glass-transition temperature of the resin and below a thermal decomposition start temperature, and the temperature is below a thermal degradation temperature of the carbon fibers.

Abstract: A parking assistance apparatus includes a processor and a memory. The processor extracts a parking space from a surrounding image of a vehicle and generates an image in which a target parking position is in overlap with the parking space, the surrounding image being captured by an imaging apparatus provided in the vehicle. The memory stores history information associating a parking position of the vehicle with the parking space. The processor adjusts a position of the target parking position in the image on the basis of the history information.

Abstract: A lens unit includes an optical system for forming an optical image of a subject. The optical system includes an optical member. The optical member is disposed closest to the subject. The optical member includes a subject-side surface having at least one groove provided thereto. The optical member transmits the optical image of the subject.

Abstract: In a fastener chain, at least some warps constituting a woven fastener tape are provided with a flame retardant phosphorus-copolymerized polyester fiber and wefts constituting the same fastener tape are provided with a synthetic fiber that is not phosphorus-copolymerized and that has a higher degree of tensile strength than the flame retardant polyester fiber. With this configuration, superior flame retardancy can be stably obtained and there is no variance in the flame retardancy of the fastener chains. In the fastener chain, the heat contraction of the warp is used to improve the chain horizontal pull force, and by increasing the frictional resistance between the warp and the weft, shifting of the weave pattern of the fastener tape can be prevented. Further, the fastener chain can be provided at a low cost because of the small amount of flame retardant polyester fiber used.

Abstract: Provided is a vehicle driving assist device which can clearly display superimposing guide lines on an image captured from the surrounding area of a vehicle without increasing the areas of the superimposing lines. The vehicle driving assist device displays an image captured from the surrounding area of a vehicle on a vehicle monitor. The vehicle driving assist device comprises: an imaging unit mounted in a vehicle for capturing the image from the surrounding area of the vehicle; and an image processing unit for displaying superimposing guide lines on the image output from the imaging unit. The image processing unit displays the guide lines in a manner such that colors are periodically altered in the length directions thereof and displayed.

Abstract: Provided is a vehicle driving assist device, said device being capable of reliably and accurately warning any driver, regardless of the perception or skill thereof, to avoid collisions with obstacles. Said driving assist device, which uses a monitor in the vehicle to display images taken of the surroundings of the vehicle, has: an imaging unit that is mounted in the vehicle and takes the aforementioned images; an information-acquisition unit that acquires vehicle-speed information; and an image-processing unit that processes image signals configured by the images outputted from the imaging unit. Said image-processing unit contains an image-superimposition unit that superimposes, onto the taken images, images pertaining to the braking distance corresponding to the vehicle-speed information acquired by the information-acquisition unit.
