摘要： A load sensor is formed of a block, at least one parallel plate structure composed of three or more thin-walled plates formed by two or more through-holes extending in the same direction through the block, and detection means provided with the thin-walled plates at prescribed locations thereof. The load sensor can detect greater forces without increasing its external dimensions at the portion in which its parallel plate structure is included, and can also show high rigidity against forces and moments in directions other than the intended direction.

摘要： A multi-axis load sensor comprises at least one radial plate structure adapted to detect a moment to be produced about its standard axis by a load, and at least one of a parallel plate structure adapted to detect a force to be produced in the direction of its standard axis by the load and another radial plate structure adapted to detect a moment to be produced about its standard axis by the load. The standard axis of the former radial plate structure is neither coincident with nor parallel to the standard axis of the at least one of the parallel plate structure and latter radial plate structure. The above sensor can reduce interactions of detected signals to extremely low levels, while showing good detection sensitivity and large strength and rigidity and making detection characteristic linear.

摘要： A load detector which includes a pin-like member arranged between force-transmitting members, a hole formed in the pin-like member along its neutral axis for bending deformations thereof, an insertion member inserted in the hole and having at both end parts thereof securement portions and at a central part thereof one or more deformation-sensing portions which are provided with their axis of symmetry coincident with the neutral axis of the pin-like member, are responsive to each load applied to the pin-like member, undergo deformations and hence enlarge the resulting strain, and a mechanism for converting the extent of deformation of the deformation-sensing portions into signals so as to obtain only portion of the resulting strain which portion has been produced by each shear deformation of the pin-like member. Owing to the position of the hole, the pin-like member has sufficient strength and rigidity and can thus be used as a connecting pin or bolt. The load detector can detect loads with high sensitivity even if the points of action of the loads change.

摘要： The present invention provides a suction and injection pump capable of transferring a sufficient amount of viscous liquid even with a very thin suction and injection pipe, thereby enabling suction or injection of a viscous liquid while minimizing invasion into a human body. A pump according to the present invention effectively sucks or injects a viscous liquid by housing a very thin rotor in a cylindrical needle and positively transferring the liquid based on the mechanical configuration of the rotor. The configuration of the present invention reduces the diameter of a pipe while minimizing invasion into a human body.
