  • Patent number: 8419491
    Abstract: When a movable blade cuts a distal end portion of a ground electrode member and is pulled back along a cut surface formed at a distal end of the ground electrode member, the distal end portion may move in the pull-back direction of the movable blade due to friction generated between the movable blade and the cut surface. This movement could cause deflective deformation of the ground electrode member. In order to restrain such movement, a support part is provided on the movable blade via a spring located near the cut surface. During the pull back step, the support part presses and supports the portion of the cut ground electrode member near the distal end thereof. Therefore, even when friction is generated when the movable blade is pulled back, the ground electrode member does not undergo deflective deformation.

  • Publication number: 20130078068
    Abstract: A compact excavator includes an operator's cab with a door capable of opening and closing an opening surface forming a boarding port. The door includes one door piece, and has a flexing portion which is closer to a front pillar than the central portion of the door when the door is in a closed state. The flexing portion is shaped to have a first area so formed that when the door is in a closed state, the first area approaches the opening surface as the first area approaches the front pillar, and a second area arranged continuously with the first area and nearer the front pillar than the first area and being formed so that the second area draws away from the opening surface as the second area approaches the front pillar.

  • Publication number: 20130058747
    Abstract: [Problem] To provide a construction machine with a step arranged in an operator's cab, which makes it possible to enlarge the shape or dimensions of the step without increasing a swing radius. [Solution] In a compact excavator provided with a step that facilitates ingress to and egress from the operator's cab (6), the step is provided at a part thereof with an outwardly-extending edge portion (12a) that extends out beyond an opening plane (16) forming an ingress/egress opening (20), and a door (5) is provided at a part thereof with a convex part (5a) that covers the outwardly-extending edge portion (12a) of the step when the door (5) is in a closed position.

  • Publication number: 20130011232
    Abstract: An upper revolving structure is provided on a lower traveling structure, and a floor member and a cab box are provided on a revolving frame of the upper revolving structure. A rear side of the floor member serves as an operator's seat mounting section, and a front side thereof serves as a footrest section, a front side thereof being formed as a lever/pedal mounting section. The footrest section is constituted by a flat operator's seat front plate which is provided on a front side of the operator's seat, a downward plate which is set downward from a left side end portion of the operator's seat front plate on a left side of the cab box, and a flat footstep plate which extends toward a door on which the operator puts his or her foot when getting into or out of an operating room.

  • Patent number: 8264716
    Abstract: A method for ringtone, voice, and sound notification of printer status, comprising obtaining status information of a printer, converting it into an audible report, and delivering the audible report. The method is especially useful for visually-impaired users and for shared printers in crowded situations where it is difficult for each user to see the panel or monitor display. The methods also include detection by the events controller, UI manager instructing an audio manager, codec decoding an audio file in firmware and hardware organization; job owner identification information embedded into a print job with a unique tag; user identification sound data embedded in a print job; audible report for multiple jobs in a job queue, with positional information; text-to-speech conversion; unique ringtone melody for each user, comprising department prefix, higher pitch modulation for higher priority, and automatically converting an alphanumeric character into the corresponding note.
