  • Patent number: 8821104
    Abstract: A loader work machine is disclosed in which a base portion of each of right/left arms (77) is received by an arm support portion (164) of a first lift link (81) and pivotally supported by a first arm shaft (88), and a hydraulic pipe arrangement (167) connected to a hydraulic actuator (98) extend through an support frame (11) from inside to outside of its inner wall (12), and toward an arm (77). The base portion of the arm (77) is supported to the arm support portion (164) at a position adjacent a link outer wall (157) in a transverse direction so that a hose accommodation space (165) is formed between a link inner wall (156) and an internal side face of the base portion of the arm (77). The hydraulic pipe arrangement (167) runs frontward of the first arm shaft (88) and a first link shaft (85), and is disposed in the hose accommodation space (165).

  • Patent number: 6055263
    Abstract: A solid-state laser oscillating device which is inexpensive and capable of obtaining a high power. A plurality of laser crystals (YAG laser crystals, etc.) (1a, 1b, 1c) are arranged along the optical axis of an optical resonator so as to maintain optical contact with one another. Adjacent ones of the laser crystals have surfaces facing each other with an adhesive layer (10, 20) interposed therebetween, to form an array in a straight-line as a whole. An adhesive having a low light absorbance with respect to a laser beam of oscillation wavelength or an excitation light is used for forming the adhesive layers (10, 20). If the refractive index of the adhesive is substantially equal to that of the laser crystals, optical matching is achieved. The adhesive layers (10, 20) may be replaced by some other transparent material. The adjacent laser crystals may be arranged with a narrow gap therebetween or held in surface contact with each other.
