摘要： A linear electromagnetic driving apparatus includes a substantially rectangular tube-shaped magnetic yoke comprised of outer and inner frame plates spaced apart to form a gap with at least one magnet secured to an outer or inner frame plate to generate magnetic flux. A bobbin supporting a coil which extends in a direction parallel to the longitudinal axis of the magnetic yoke is positioned in the gap. A driven member is secured to and coaxial with the bobbin and has openings to receive the inner frame plates of the yoke such that when the coil is energized to move the bobbin in the gap, the inner frame plates extend into and through the bobbin and into and through the openings of the driven member. A fixed shaft extends parallel to the longitudinal axis of the yoke; and a bearing secured to the bobbin structure and extending outwardly therefrom receives and is slidable on the fixed shaft. At least one of the corners formed on the rectangular tube-shaped yoke is cut out to define an open portion through which the bearing passes so as to be unobstructed as the bobbin slides within the yoke.

摘要： Hydrophilic graphite-base powder is provided wherein hydrophilic small particles of such as silicon carbide or silica are mixed with a graphite powder and the small particles are attached to each surface of the graphite particles by performing a mechanical impact treatment in a high-speed gas flow. By combining the graphite-base powders with refractory compound powders of such as magnesia or alumina to be a powder mixture for monolithic refractories containing graphite, a formed body of the powder mixture having a large bulk density can be provided and a service life thereof is comparable to that of a shaped refractory, and labor and energy necessary for the production process and the operation are saved.

摘要： A novel lens barrel which includes a comparatively small number of parts, has a comparatively low weight and can be produced at a comparatively low cost. The lens barrel apparatus comprises an outer shell, a lens holding member holding a focusing lens thereon and mounted in the outer shell for movement in a direction of an optic axis of the focusing lens, and an actuator including an actuating coil secured to one of the lens holding member and the outer shell and wound around a coil bobbin. The actuator further includes a magnet secured to the other of the lens holding member and the outer shell in a coaxial relationship with the actuating coil around the optic axis, and a detecting coil is wound on the coil bobbin in an overlapping relationship with the actuating coil for detecting a speed of movement of the focusing lens.

摘要： A lens barrel for a camera wherein an outer profile thereof has a reduced dimension in a radial direction of a movable lens and with a lens holding member that can be moved smoothly in a direction of an optical axis of the movable lens held on the barrel. The lens barrel comprises an outer shell having a pair of guide portions provided therein and a lens holding member holding a movable lens thereon. The lens holding member has a pair of guide portions provided at the opposite locations thereof with respect to the optical axis and is supported at the guide portions thereof for sliding movement on the guide portions of the outer shell. The lens barrel further comprises an actuator including a coil securely mounted on the lens holding member and a magnet securely mounted on the outer shell. The coil and magnet are disposed coaxially to each other around the optical axis. Position detecting means is disposed in a spaced relationship by substantially equal distances from the guide portions of the lens holding member and detects a position of the lens holding member with respect to the outer shell.
