摘要： A magnetic recording head that includes a combined IN element and an MR element is heat treated under two types of magnetic fields. A rotating magnetic field, having a first magnetic field intensity, is applied for a time while the magnetic recording head is at an elevated temperature. Then, part-way during cooling of the magnetic head, the rotating magnetic field is replaced by a direct (non-rotating) magnetic field having a second magnetic field intensity. The second magnetic field intensity is lower than the first magnetic field intensity, whereby the properties of both the IN element and the MR element are maintained at high values.

摘要： A taking lens consists of first to third lens groups. The second lens group is held in a lens frame that is coupled through an arm to a supporting shaft, and is able to rotate about the supporting shaft, to move the second lens group in a circular direction in a plane perpendicular to an optical axis of the taking lens. As a movable lens barrel retreats into a camera body, the lens frame rotates to remove the second lens group from an inserted position inserted in an optical path of the taking lens to a removed position set out of the optical path. The arm is provided with an actuator that causes the lens frame to move in a lengthwise direction of the arm. Because the movement in the circular direction includes a component that is perpendicular to the lengthwise movement of the arm, it is possible to move the lens frame and thus the second lens group in any directions in the perpendicular plane to the optical axis, in order to cancel a deviation of an optical image that result from a camera shake.

摘要： A thin-film magnetic head is disclosed that includes a lower magnetic core and an upper magnet core formed on the surface of a substrate and connected together at a first end thereof, a magnetic gap is formed between the lower and upper magnetic cores at a second end thereof, and a coil-form electric conductive layer is located between the lower magnetic core and the upper magnet core. The lower and upper magnetic cores have a saturated magnetic flux density from 10,000 G to 18,000 G, while the magnetic permeability along the magnetic path of the magnetic head is 3,000 or higher at a frequency of 10 MHz. The unique characteristics of the magnetic head are obtained by heating an arrangement comprising the lower and upper magnetic cores, the magnetic gap layer, and the electric conductive layer to a temperature above 325.degree. C., and applying an external magnetic field greater than 0.01 kOe to the lower and upper magnetic cores to relax their magnetic anisotropy as the lower and upper magnetic cores are cooled during the manufacturing process.
