摘要： A two-drive-system fluid pressure chuck including two sets of jaw members capable of chucking a workpiece from two directions X and Y. The chuck includes two cylinder apparatuses, a first rod, a second rod, and a cam member. The first rod being slidably disposed within the inside of the second rod. The cam member is formed at the tip of each rod and is used to convert the reciprocal operation of each rod into the opening and closing operations of the jaw members. A notch is formed in the side of the second rod, and the cam member of the first rod protrudes out from the second rod through this notch to connect to the jaw member.

摘要： A spring or springs are provided between driving-side members that operate together with an output shaft of a stepping motor, and driven-side members that operate together with a jaw member. Thereby, when the jaw members performs opening motion, the driving-side members and the driven-side member directly engage with each other, thereby allowing a driving force to be transmitted directly from the output shaft to the jaw members. When the jaw members performs workpiece-holding operation, the driving-side members and the driven-side member engage each other via the spring or springs, thereby allowing the driving force to be elastically transmitted from the output shaft to the jaw members via the spring or the springs. In this configuration, when the workpiece-holding operation is performed by the jaw members, the stepping motor is controlled so as to over-rotate in a buffered manner.

摘要： In a slide actuator, a central guide rail having V-shaped grooves defined therein and opened at 90 degree angles, is mounted on a cylinder body. A slide table is brought into engagement with the guide rail. Guide members having V-shaped grooves defined therein are provided inside the slide table so that they are opposed to the grooves defined in the guide rail. Cylindrical roller bearings are alternately fitted at inclinations of 90.degree. in their corresponding channels defined by the opposed grooves. Thus, when the roller bearings are rolled, the slide table is displaced with higher accuracy and a load supported by the slide table is transmitted to the guide rail from the roller bearings.

摘要： The fine barium titanate particles of the present invention have an average primary particle diameter of from 10 nm to less than 20 nm, a sphericity of 1.00 to 1.18, and a ratio of an average secondary particle diameter to the average primary particle diameter of 0.7 to 6.0. The fine barium titanate particles of the present invention can exhibit a small behavior particle diameter and can be readily monodispersed notwithstanding very fine particles, and as a result, can be suitably used as various dielectric materials because the particles are free from aggregation therebetween and have an excellent dispersibility.
