摘要： A pair of parallel rectangular windows are punched out in a thin sheet base material having the same thickness as that of a short hand part (13) including a weight part (13a) of a second hand (10) so as to form a hand forming part between the pair of windows and a part in the hand forming part forming a long hand part and a mounting part of a hand is pressed so as to form a thin wall part. Then, the second hand in a final shape is punched out from the base material so that a long hand part (11) and a mounting part (12) are formed with the thin wall part of the hand forming part and the short hand part (13) is formed with an original thickness part. Consequently, the second hand for an analog electronic timepiece in which the weight part (13a) is provided on the short hand part (13) can be easily and securely manufactured only by a press working.

摘要： An electrostatic actuator allows a movable electrode to move in response to the generation of electrostatic attraction between the movable electrode and the first stable electrode wall as well as between the movable electrode and the second stable electrode wall. An insulating solid piece is interposed between the first and second stable electrode walls so as to connect the first and second stable electrode walls to each other. The insulating solid piece serves to enhance the rigidity of the first and second stable electrode walls. A higher rigidity can be established in the first and second stable electrode walls of the electrostatic actuator even if the wall thickness of the first and second stable electrode walls is reduced. The reduced wall thickness of the first and second stable electrode walls enables arrangement of the first and second stable electrode walls as many as possible within a limited space. As the number of the stable electrode walls, opposed to the movable electrode, gets increased, a larger driving force can be generated to act on the movable electrode in the electrostatic actuator.

摘要： A head slider includes a front rail having an air bearing surface and a step surface lower than the air bearing surface, provided on a disk faced surface in the vicinity of an air inflow end, a transducer provided in the vicinity of an air outflow end, and a groove for generating a negative pressure by expanding air once compressed by the front rail. The head slider further includes a piezoelectric actuator mounted on a head slider back surface on the opposite side of the disk faced surface excluding the vicinity of the air outflow end. By the piezoelectric actuator, the front rail and the neighboring portion are deformed in the direction toward the recording medium or away from the recording medium, and the positive pressure generated at the air bearing surface is regulated, whereby the floating amount of the head slider can be regulated.

摘要： A pair of slits are defined in a slider body of a head slider so as to extend from a trailing end surface to the leading end on the slider body. A movable block is established in the slider body between the slits. The slits ensure the extent of movement for the movable block. Elongated plates enable a relative displacement between the movable block and a stationary block. A head element is mounted on a trailing end surface of the movable block. The thickness of a non-magnetic layer corresponds to the gap length of the head element. The gap length of the head element can easily be controlled based on deposition of the non-magnetic layer. The thickness of the non-magnetic layer can be reduced in a relatively facilitated manner, so that the gap length of the head element can easily be minimized.

摘要： In an analog electronic timepiece in which the rotation of a rotor (1a) step motor (1) is decelerated through train wheels before it is transmitted an hour hand (17) and a minute hand (15), the gravity center of a center wheel composed of a center wheel gear (9), a center wheel pinion (10), and a center wheel shaft (11) to which the minute hand (15) is mounted is displaced from the axis of the center wheel shaft (11) to within an angle range of less than ±90° with respect to the opposite direction to a direction in which a time indicating part (15a) of the minute hand (15) extends so as to reduce a moment on the center wheel shaft (11) caused by a combination of the minute hand (15) and the center wheel. This makes it possible to prevent a hand-skip due to disturbance even if the value of holding energy of the step motor (1) is reduced.
