Abstract: To provide a rotor drive mechanism which realizes that a rotor rotating at high speed can be used by reducing the amount of heat and vibrations generated when the rotor is rotated at high speed and lowering a contact pressure between an outer surface of the rotor and an inner surface of a stator inner hole or preventing the outer surface of the rotor and the inner surface of the stator inner hole from contacting each other. A rotor drive mechanism (53) is capable of causing an external screw type rotor (22) of an uniaxial eccentric screw pump (23) to rotate and carry out a revolution movement, the uniaxial eccentric screw pump (23) is configured such that the external screw type rotor (22) is attached to an inner hole (29a) of an internal screw type stator (29), and the external screw type rotor (22) is caused to rotate by a rotation speed control driving portion (26) and is caused to carry out a revolution movement by a revolution speed control driving portion (24).

Abstract: A double/triple-thread single-shaft eccentric screw pump is provided. The rotor of the pump overhangs little in comparison with the flange type connecting structure. The whole length of the pump is short, and the pump casing of the pump is short and small in diameter, so that the pump is small in size and light in weight. One end of a flexible rod is tapered and has a tapped hole formed at its axis. One end of the rotor has a tapered bore formed at its axis, into which the tapered end of the flexible rod is fitted. The rotor has a through bore formed at its axis, through which a tension bolt extends from the other end of the rotor. The tension bolt has a front threaded end, which is screwed into and fastened to the tapped hole of the flexible rod.

Abstract: A wheelchair scale is provided wherein triangular or trapezoidal box-shaped members are used for forming a support base having a truss structure. The box-shaped members are formed in advance by welding, and are then welded together. Since the welding processes can be performed separately, work efficiency is improved. In addition, since the support base has a truss structure, it supports a large amount of weight without deflection, even though its thickness is relatively small. In addition, the weight of the support base is reduced compared to a conventional base having a pipe structure. Furthermore, because the height of the support base from the floor is reduced compared to a typical conventional structure, a wheelchair can be easily moved onto the support base.

Abstract: In a multipoint scale for weighing a load applied to a placement section by a plurality of weight sensor units, the weight sensor unit includes a weight sensor having a strain-sensitive part; a first flexible elastic member for receiving the load applied to the placement section; a load transmission part for transmitting the load from the first flexible elastic member to a power point of the weight sensor; a load support part for supporting a fulcrum of the weight sensor; and a second flexible elastic member for receiving the load applied to the load support part and for maintaining a direction of the load applied to the strain-sensitive part of the weight sensor to be vertical in accordance with a deflection of the first flexible elastic member. Torsion of the weight sensor is avoided by reducing the effect of deflection of the placement section on transmission of the load to the weight sensor.

Abstract: In a load transfer mechanism which transfers load to a load cell that constitutes a Roberval mechanism, a load transfer member has at least an area right above a load cell mounting section in the top surface thereof as a concave surface area formed to be lower than the remaining area of the top surface thereof so that it does not contact a cover member. Thus, if the barycentric position of the load of an object to be weighed placed on the cover member, regardless of whether the load is concentrated load or divided load, the load transfer mechanism can reduce the difference of the influence of deflection of the load transfer member or moment imposed on the load, transfer given load to the load cell through the load transfer member and decrease a span error produced by the load position of an object to be weighed.

Abstract: Disclosed is an apparatus for autonomously compressing, phase-compensating and waveform-shaping an ultrashort light pulse that is fast and high in sensitivity in compensating for phase fluctuations and allows the use of a usual laser light source that is low in light intensity and has large temporal fluctuations in phase.
