  • Patent number: 8104842
    Abstract: An upper cross beam 10 for supporting a rear side of a cab 19 from below is formed as a separate member from a base frame 7. This upper cross beam 10 is separably mounted on left and right column portions 7E of the base frame 7 by using bolts 12. Namely, when an engine 27 is mounted to the base frame 7, the upper cross beam 10 is separated in advance from the base frame 7. Consequently, at the time of the operation of carrying in the engine 27, it merely suffices to vertically hoist or lower the engine 27 by use of a crane. It is thereby possible to carry in the engine 27 between the column portions 7E of the base frame 7 without being hampered by the upper cross beam 10.

  • Patent number: 7525772
    Abstract: A magnetoresistive device includes a magnetoresistive film and a pair of electrodes for applying a sense current substantially perpendicularly to the magnetoresistive film. The magnetoresistive film includes a magnetization pinned film including a first ferromagnetic layer having a magnetization direction substantially pinned in one direction, a magnetization free film including a second ferromagnetic layer whose magnetization direction changes in accordance with an external magnetic field applied thereto, an intermediate layer formed between the magnetization pinned film and the magnetization free film and having an insulating film and a metal conduction portion extending in the film thickness direction of the insulating film, and a layer containing an electrovalent or covalent compound formed near the metal conduction portion.

  • Patent number: 5727105
    Abstract: An optical element-optical fiber composite structure having a high resistance of the optical fiber to breakage due to cyclical change in temperature, includes a package structure having a main container, side containers attached to the main container and sleeves through which a main chamber of the main container is connected to side chambers of the side containers; an optical element housed in the main chamber; and optical fibers introduced into the main chamber through the side chambers and the sleeves and connected to the optical element.
