摘要： A permanent magnet (17) of a meter portion (3) (FIG. 2A) has a disc shape having a hole formed in a center thereof, and is magnetized in an axial direction of a central shaft (18). In a bottom surface of the permanent magnet (17), magnetic domains are formed so that one side constitutes North pole and the other side constitutes South pole. Coils (15a, 15b) are wound on the same plane to form surfaces parallel to the bottom surface of the permanent magnet (17), and are arranged on one bottom surface side of the permanent magnet (17) at a predetermined distance from the permanent magnet (17). An outer spiral spring (11) and an inner spiral spring (12) are formed to be helical on the same plane. Each of those spiral springs is fixed to a bridge (42) at one end thereof and is fixed to a coil (15) at the other end thereof. The coil (15) is urged in a direction opposite to a direction in which an indicator needle (13) (which rotates about the central shaft (18) together with the coil (15)) swings.

摘要： A drive unit 20, comprising a moving body 24 and a friction drive member 26 fixedly attached at each end of a piezoelectric element 22 in the layer direction, is disposed between a pair of fixed friction members 14 having a plurality of divided contact parts 15 divided by notches 14s formed at equal spacing along the movement path of the friction drive member 26. The divided contact parts 15 are arrayed so as to be slightly inserted into the movement path of the friction drive member 26, and become elastically deformed when in contact with the friction drive member 26 so as to exert a force on friction drive member 26 in reaction thereto. This exerted force remains uniform regardless of the relative position of the friction drive member 26.

摘要： A driving apparatus using a transducer. The apparatus comprises an electromechanical transducer, a driving shaft, a moving member and a pushing member. The driving shaft is coupled with the electro-mechanical transducer; the moving member is pushed against the driving shaft for frictional coupling therewith, the pushing member being interposed between the driving shaft and the moving member. The moving member is connected with the target moving object such as a lens mechanism. In operation, the electromechanical transducer is fed with driving pulses of a frequency of at least 18 kHz so that the transducer and the driving shaft will be displaced slowly in one direction and rapidly in the opposite direction, whereby the moving member coupled frictionally with the driving shaft is driven axially in a reciprocating manner at two different velocities. Repeating these operations allows the moving member to move slowly in the same axial direction in which the driving shaft is driven, whereby the lens mechanism or the like connected to the moving member is moved up to the desired position.

摘要： A propulsive air stream deflecting apparatus for an air cushion vehicle is provided on the hull of the air cushion vehicle for arcuately deflecting the propulsive air stream from the open rear end of the air duct, mounted to the hull. The deflecting mechanism provides a steering thrust to the air cushion vehicle. The deflecting mechanism is pivotable about a vertical pivot mounted to the hull between a propulsive thrust producing position, where the deflecting mechanism is located away from the propulsive air stream issuing from the rear open end of the air duct, and a forward thrust producing position where the deflecting mechanism fully covers the rear open end of the air duct for deflecting the propulsive air stream to create the forward thrust to the hull. The deflecting mechanism is operatively connected to a controlling mechanism which controls the pivotal movement of the deflecting mechanism to locate the deflecting mechanism at a position between the propulsive thrust producing position and the forward thrust producing position.
