Abstract:
Provided are an underwater propulsion aid and an underwater garment equipped with the same that enable a user to walk on land or get on or off a boat or the like while wearing them, that have high fashionability and safety, and that enable even a user with weak muscular strength and a user having no experience of using them to easily obtain a propulsive force in water. An underwater propulsion aid 1 includes a base portion 2 that is formed in accordance with a curved shape of a shank and that is fitted to a part from a knee to an ankle, and a pair of front fins 3 that are protruded to right and left outer sides from both right and left side surfaces of the base portion 2 while continuing to a curved surface of a shin.
Abstract:
Disclosed is a connecting structure that enables a lid body to be connected by the slight rotation thereof in either direction, and that is robust with respect to use in many environments including sandy or dusty environments. A connecting structure (1A) for connecting a first member (2A) and a second member (3A), wherein the first member (2A) comprises a connecting upright portion (21) and a plurality of locking flanges (22) provided to extend outwards along the circumferential direction of the outer face of the connecting upright portion (21), while the second member (3A) comprises a connecting side-wall portion (32) that overlies the connecting upright portion (21) and a plurality of locking projections (33) provided to extend inwards from the inner face of the connecting side-wall portion (32). The bottom faces of the locking flanges (22) distend downwards in a convex curved shape and, when the second member (3A) is overlaid on the first member (2A) and rotated, the upper faces of the locking projections (33) are guided with sliding contact along the convex curved bottom faces (23) of the locking flanges (22) and stopped at the lowermost position of the convex curved bottom faces (23).
Abstract:
A semiconductor integrated circuit is provided which includes: A signal input terminals which include control input pads, A being an integer greater than or equal to 2; an internal circuit; a clock signal input terminal to which a clock signal is input; and an input signal control block which, in a test mode, separates time-division multiplexed data having a multiplicity of X, the time-division multiplexed data being input from A/X signal input terminals among the A signal input terminals, into individual data in accordance with the clock signal, and outputs the separated individual data to the internal circuit, X being an integer greater than or equal to 2.
Abstract:
Provided is a buoyant aerial vehicle which can secure high safety by reducing the risk of crashing, and which can facilitate control of movement by suppressing the influence of wind and exhibit high mobility capability. The buoyant aerial vehicle is configured by including: a buoyant vehicle body in which gas having a specific gravity smaller than air is hermetically filled; a vertical propulsion propeller which provides vertical propulsive force to the buoyant vehicle body; and a horizontal propulsion propeller which provides horizontal propulsive force to the buoyant vehicle body, and is configured such that the buoyant vehicle body has horizontal wind passages formed in at least two directions, and has outer peripheral edges each formed into an acute angle in side view.
