  • Publication number: 20080257716
    Abstract: A film is formed at a high rate on the surface of an iron-boron-rare-earth-metal magnet having a given shape, while effectively using dysprosium or terbium as a film-forming material. Thus, productivity is improved and a permanent magnet can be produced at low cost. A permanent magnet is produced through a film formation step in which a film of dysprosium is formed on the surface of an iron-boron-rare-earth-metal magnet of a given shape and a diffusion step in which the magnet coated is subjected to a heat treatment at a given temperature to cause the dysprosium deposited on the surface to diffuse into the grain boundary phase of the magnet.

  • Publication number: 20070245851
    Abstract: To improve the performance of a rare-earth magnet, it is effective to use a low-oxidized powder having a small grain size. One objective of the present invention is to provide a method for manufacturing a sintered rare-earth magnet having a magnetic anisotropy, in which a very active powder having a small grain size can be safely used in a low-oxidized state. Another objective is to provide a method capable of efficiently manufacturing products having various shapes. In a weighing and loading section 41 and a high-density loading section 42, a fine powder as a material of the sintered rare-earth magnet having a magnetic anisotropy is loaded into a mold until its density reaches a predetermined level. Then, in a magnetic orientation section 43, the fine powder is oriented by a pulsed magnetic field. Subsequently, the fine powder is not compressed but immediately sintered in a sintering furnace 44.

  • Publication number: 20070212056
    Abstract: A single-lens reflex camera has a first image pickup device as a main image pickup device, a second image pickup device for live-view observation, a reflection mirror which switches an optical path between an optical path directed toward the first image pickup device and an optical path directed toward the second image pickup device, and a control section. When the shooting operation is instructed with the second image pickup device driven and a live-view displayed, the control section starts driving the reflection mirror to retract the reflection mirror from the optical path, and stops the second image pickup device and starts driving the first image pickup device while the reflection mirror is driven in a retracting direction.

  • Publication number: 20060114346
    Abstract: A sensed image and shooting time information corresponding to the sensed image are stored on a memory card. A display unit comprises a plurality of display areas at specific consecutive shooting times and displays the shooting time in the display area. A CPU specifies a display area in which a sensed image corresponding to the shooting time as an image-existing area, and enables the display unit to visibly indicate the image-existing area of the display areas specified as the image-existing area, based on a prescribed condition by a cursor. In this case, when the movement of the display area is instructed, the CPU moves only the image-existing area and indicates the existence of an image, by controlling the movement of the cursor.

  • Publication number: 20060047264
    Abstract: A fluororesin tube body (10) of an endoscope flexible tube (1) is small in diameter and thin in wall thickness to such a degree that it is difficult to maintain its cross-sectional shape by itself when the flexible tube (1) is bent to the limit. A braid (20) woven from a plurality of flat bands (21) to form a tubular shape is disposed around the tube body (10). The mesh openings of the braid (20) are filled with filling adhesive (30), which bonds the tube body (10) and the braid (20) together. The filling adhesive (30) has enough elasticity to allow deformation of the braid (20) during the bending operation and enough adhesive strength to maintain the bond between the tube body (10) and the braid (20) even when the filling adhesive (30) is elastically deformed. Consequently, the braid (20) restricts the cross-sectional deformation of the tube body (10). Thus, the limit curvature of the flexible tube (1) can be increased.
