Abstract: A medium transport device includes a first transporter configured to transport a medium by nipping the medium along with rotation, a second transporter configured to transport the medium and disposed on an upstream side of the first transporter in a transport direction of the medium, a first adjuster configured to adjust a position of the medium in a width direction by moving the first transporter and the second transporter in the width direction of the medium with the medium nipped by the first transporter and the second transporter, and a second adjuster configured to adjust a contact pressure of the first transporter for the medium and a contact pressure of the second transporter for the medium based on resistance caused when the medium is moved in the width direction.

Abstract: A sheet transporting device includes: a skew correcting component configured to correct any skew of a sheet by executing speed-gap driving in which first and second transporting components that are arranged at respective positions in a direction intersecting a direction of sheet transport are driven for a predetermined time period with a speed gap between the first and second transporting components; and a changing component configured to change, with reference to a characteristic relevant to sheet transport, a state of the speed-gap driving of the skew correcting component.

Abstract: A sheet transporting device includes first and second position correcting components provided at respective positions in a direction of sheet transport and each being configured to correct a position of a sheet in a direction intersecting the direction of sheet transport by being shifted in the direction intersecting the direction of sheet transport while holding the sheet, and a changing component capable of changing an amount of correction of the position of the sheet individually for the first and second position correcting components.

Abstract: An operation data recording device 11 mounted at a work machine detects and records operation data of the work machine. The operation data is collected by an external terminal 13 and transmitted from the external terminal 13 to a server 23 located in a remote place. When the operation data is collected by the external terminal 13, a program for the operation data recording device of the work machine is updated to the latest version by the external terminal 13. When transmitting the operation data from the external terminal 13 to the remote server 23, an external terminal program and a program for the operation data recording device stored in the external terminal 13 are updated to the latest versions.

Abstract: In an electronic control system for a construction machine, a governor control unit, an excavator body control unit, and an electric lever control unit are interconnected for transmission and reception of data. A universal communication line is connected to the governor control unit and is adapted for an interface in conformity with universal communication standards A dedicated communication line is connected to the excavator body control unit and the electric lever control unit and is adapted for an interface in conformity with dedicated communication standards different from the univeral communication standards. A communication relay control unit is used for, converting and transmitting communication data received from one of two systems of the communication lines to be in conformity with the communication standards of the other communication line.

Abstract: An intermediate server 6 or a main server 5 executes the steps of displaying a work site of a construction machine or a predetermined area regarding the work site on a subcontractor's personal computer 62, prompting an input for applying to an order for work of repair/replacement of parts belonging to a predetermined component section of the construction machine, extracting the predetermined qualification requirements, which have been stored in a database 6A beforehand, from the database based on received applying information, producing an examination sheet for determining whether a local subcontractor meets the extracted qualification requirements, transmitting the examination sheet produced in the producing step to the subcontractor's personal computer 62 via a communication network, and prompting an input in predetermined places of the examination sheet.

Abstract: An information providing system for a construction machine has a plurality of information terminals (4) provided on the side of users or owners of hydraulic excavators (1), a main server (5) provided on the side of a manufacturer of the hydraulic excavators, and an intermediate server (6) provided on the side of a dealer in charge of services presented to the users or the owners. The main server (5) obtains data regarding machine operation of each hydraulic excavator (1) via information communication and stores the obtained data in a database (5A ), and outputs the obtained data regarding the machine operations of the plurality of hydraulic excavators (1), as basic information for services presented to the users or the owners, to the intermediate server (6). The intermediate server (6) outputs, to the corresponding information terminal (4), the basic information directly or after optionally selecting the basic information.

Abstract: In an electronic control system for a construction machine, a governor control unit (17), an excavator body control unit (23), and an electric lever control unit (33) are interconnected for transmission and reception of data.

Abstract: An incandescent lamp assembly has a generally elliptical vitreous envelope including a cylindrical neck, stem mount with a pair of lead-in wires, and a screw-in base capped on the cylindrical portion of the envelope. The cylindrical neck of the envelope has a circular protruded ring along the entire periphery thereof and in the corresponding position of the screw-in base is provided a concave channel, for a push-in coupling. A flared rim is integrally formed with the concave channel and extends gradually outwardly to bear along the envelope, giving elastic deformation to the upper half of the screw-in base. The lead-in wire is interposed between the cylindrical neck and the screw-in base and fixedly positioned at the circular protruded ring. For prevention of relative rotational movement, heat resistant silicone rubber is applied on the circular protruded ring.
