Abstract: An excavator includes: a swing motor driven by oil from a swing pump coupled to a power take-off and driven by an engine; a first main oil passage connecting a first discharge port of the swing pump and a first suction port of the swing motor; a second main oil passage connecting a second discharge port of the swing pump and a second suction port of the swing motor; a neutral retention valve disposed in the first main oil passage and the second main oil passage and controlling passage of oil; a regenerative energy absorbing device coupled to the power take-off and absorbs regenerative energy generated by oil from the swing motor to the swing pump via a meter-out opening of the neutral retention valve; and a valve control section controlling an area of the meter-out opening based on a state of the regenerative energy absorbing device.

Abstract: Provided is an apparatus for functional training of an ankle and toe, which can provide better service results. An apparatus for functional training of an ankle and toe includes a foot platform configured to receive a foot of a user and disposed to face a portion of the foot of the user from rearfoot to forefoot; and an artificial muscle configured to displace the foot platform when operated. The apparatus for functional training of an ankle and toe further includes a toe platform disposed to face a toe of the user when the foot of the user is placed on the foot platform. The toe platform is configured to be displaced with respect to the foot platform when the artificial muscle is operated to displace the foot platform.

Abstract: A light source device is configured to have a light source configured to emit white light, a rotatable turret provided with multiple kinds of predetermined light passing areas respectively extract light components having different wavelength ranges from the white light incident from the light source, the multiple kinds of predetermined light passing areas being arranged in a circumferential direction of the rotatable turret, and white light passing areas each allowing the white light to pass therethrough being arranged in the circumferential direction of the rotatable turret and between the predetermined wavelength light passing areas, and a driving means configured rotate the rotatable turret so that the multiple kinds of predetermined wavelength light passing areas and the white light passing areas are alternately inserted into a light path of the white light one by one at a timing which is synchronized with a predetermined photographing period.

Abstract: A scanning endoscope processor, comprising a signal generator, an extractor, a first memory, a second memory, a first connector, and a second connector, is provided. The signal generator generates a pixel signal at a constant cycle according to an amount of reflected light or fluorescence. The extractor extracts extracted pixel signals from the pixel signals that are generated by the signal generator. The first memory stores a first image signal. The second memory stores a second image signal. The first connector can be connected to a first apparatus. The first apparatus is able to receive the first image signal. The second connector can be connected to the monitor. The second image signal stored in the second memory is transmitted to the monitor via the second connector.

Abstract: A floor mat having an upper face layer and a base layer, which comprises a plane section and a marginal peripheral section surrounding the plane section, wherein at least a part of the marginal peripheral section contains a belt-like portion which is raised at the side of the upper face layer and extends continuously and substantially in parallel to a marginal peripheral edge thereof; the belt-like portion contains a channel extending longitudinally thereof at the side of the base layer; and the belt-like portion carries at least one convex-concave structure on a wall surface of the channel, with the proviso that, when the convex-concave structure extends transversely of the channel, the convex-concave structure is discontinued on at least a bottom surface of the channel, is disclosed. The floor mat according to the present invention has a sufficient peeling strength obtained by a compression process used for only a short period of time.
