Abstract:
Numerous fine projections (20) are formed interspersed on a plate-shape member (18), and the neutral plane (S) of each fine projection (20) is inclined at an inclination angle α to the normal line (O) such that the contact center (Q) does not overlap with the base part in the plane direction of the surface (22), so when a pressing load (F) is applied, the moment acting on the fine projections (20) is large, and the fine projections (20) easily deform to bend in the respective inclination direction. By this means, the tactile softness (cushion properties) are improved by preventing the fine projections (20) from undergoing simple compression deformation in the axial direction, and stick-slip due to friction between the fine projections (20) and the surface (22) is avoided, making it possible to obtain a smooth and stable tactile softness.
Abstract:
A laminated composite interior component, having cushioning property, including a first member having a predetermined mating surface, and a second member made of an elastically deformable resin material, having a plate portion on and parallel to the mating surface and multiple solid protrusions formed integrally with the plate portion and having tip ends that protrude toward and contact the mating surface, and flexural rigidity of each protrusion against a compressive load having anisotropy around an axis perpendicular to the plate portion. Each of the protrusions have a longitudinal shape in a transverse section parallel to the plate portion and have one or more stepped portions, with a smaller section at its tip end side, in one of a pair of sidewalls located in a lateral direction perpendicular to a longitudinal direction of the longitudinal shape. Each protrusion is tilted toward a sidewall opposite the stepped portion.

Abstract:
A test apparatus main body mounted in a single housing has a connection unit, a common bus, terminal control units, measurement units, and a total control unit. The connection unit can connect at least two terminals of identical or different type of communication systems. The terminal control units output test signals including signals that respectively control the terminals which can be connected to the connection unit based on predetermined test programs according to the type of communication systems, and measurement instructions, which are supplied via the common bus. The second measurement units perform measurements designated by the measurement instructions upon reception of response signals which are output from the terminals in response to the test signals from the terminal control units. The total control unit supplies, in advance, the predetermined test programs according to the type of communication systems and outputs the measurement instructions at predetermined timings to the terminal control units.

Abstract:
The present invention provides a pump by vessel oscillation including a vessel having an inlet for liquid and an outlet opening in a specific tangential direction of an outer peripheral portion thereof. The vessel is oscillated in a specific direction to outflow the liquid through the outlet opening. Accordingly, the liquid in the interior of the vessel undergoes a simple centrifugal motion and when the pump is used for a blood circulation device such as an artificial heart or assisted circulation device, the blood is completely shut off from outside and isolated from entry of various germs, air, foreign matter, etc. The pump is simple is construction and excellent in reliability and durability.
