A lift cylinder is attached to a center part of a vehicle body in a vehicle width direction. The lift cylinder causes a work implement to move up and down. A supporting member is attached to the center part of the vehicle body in the vehicle width direction and extends upward from the vehicle body. An imaging device is supported by the supporting member and captures images of a region in front of the vehicle body. A penetrating part is formed in the supporting member. The lift cylinder is disposed through the penetrating part.

A first capturing image unit mounted on a vehicle body captures an image of surroundings of a work vehicle. A second capturing image unit is disposed above the work implement and captures an image of an area in front of the work implement. A first image generation unit generates, from the image captured by the first capturing image unit, a surroundings composite image, which depicts the surroundings of the work vehicle in a bird's-eye view and is synthesized with a vehicle model depicting the work vehicle. A second image generation unit generates, from the image captured by the second image capturing unit, a work implement composite image, which depicts the area in front of the work implement and is synthesized with the vehicle model and the surroundings composite image. A display unit displays a display image including the vehicle model, the surroundings composite image, and the work implement composite image.

A migration-destination primary storage apparatus (MD-PDKC) comprises a second PVOL and a second journal storage area storing a journal corresponding to write data for the second PVOL, and executes a data copy to the second PVOL from a first PVOL, which is in a migration-source primary storage apparatus (MS-PDKC) and forms a copy pair with an SVOL in a secondary storage apparatus (SDKC). After the data copy has been completed, the MD-PDKC acquires the latest write sequence information from the MS-PDKC, and upon receiving a write request for the second PVOL, writes the write-request write data to the second PVOL, creates a journal by using journal data corresponding to the write data and also by using update information showing write sequence information based on the acquired latest write sequence information, and writes the journal to the second journal storage area.

A warm-up pilot pressure control unit adjusts pilot pressure inputted to a first flow channel open/close unit so that the flow channel open/close unit is switched to an open state when a warm-up start state is entered under the necessary condition that a first winch operation member is in a neutral position. When the first flow channel open/close unit is in the open state, a first pump displacement adjustment unit adjusts the displacement of a first hydraulic pump so that the differential pressure between a first pump hydraulic circuit and a first warm-up hydraulic circuit becomes constant at a predetermined set pressure.

A storage apparatus has a channel board; a drive board; a cache memory; a plurality of processor boardsthat transfer data; and a shared memory. The channel boardstores a frame transfer tablecontaining information indicative of correspondence between a LDEVand each of the processor boards, set in accordance with a right of ownership that is a right of access to the LDEV. The processor boardsstore LDEV control informationin a local memory, which is referred to by the processor board at the time of access.

Storage apparatus and method for controlling storage apparatus

A communication connecting device includes a terminal unit controller for temporarily storing data received from a sending terminal unit. A packetizer/depacketizer collectively codes the data sequentially read out in accordance with size information fed from a size information storage. The packetizer/depacketizer determines whether or not the current data is the last one of a continues sequence of data and delivers, if the answer of the decision is positive, a detection signal to a frequency-of-transmission monitor. A UDPTL controller feeds additional data read out of the buffer to the frequency-of-transmission monitor in accordance with ITU-T Recommendation T.38. In response to the detection signal, the monitor outputs a control signal such that the coded data not sent a preselected number of times are repeatedly read out of the buffer and retransmitted the preselected number of times.

Communication connecting device capable of reliably transmitting data to an IP network and a data transmission control method

In an Internet facsimile apparatus, a facsimile controller temporarily stores data received from a G3 (Group 3) facsimile apparatus or the other terminal unit to communicate with. A packetizer/depacketizer packetizes the data sequentially read out in accordance with size information fed from a size information storage and feeds the resulting packets to a UDPTL controller and a buffer. The packetizer/depacketizer determines whether data received from the other terminal unit and decoded is a response to data sent from the G3 facsimile apparatus or retransmitted data, and delivers a response detection signal representative of the result of decision to the UDPTL controller. In the UDPTL controller, a filtering circuit deletes stored past data in accordance with the response detection signal representative of a response. The apparatus reduces a load on an IP (Internet Protocol) network.

During G3FAX communication with an IP network, a FAX adaptercontrols a packet size data storagewith the use of a control signal, generated by a packet size controller, to adjust the packet size of FAX data sent from a G3FAXaccording to delay informationfrom the IP network. When sending data to the IP network, the adapterallows the size of a packet to be adjusted in response to the delay informationsent from the IP network, thus resolving a discrepancy in transfer speed.

A communication connecting device includes a terminal unit controller for temporarily storing data received from a sending terminal unit. A packetizer/depacketizer collectively codes the data sequentially read out in accordance with size information fed from a size information storage. The packetizer/depacketizer determines whether or not the data is control data and delivers, if the answer of the decision is positive, a notification control signal to a control data monitor. A UDPTL (facsimile User Datagram Protocol Transport Layer protocol) controller feeds a UDPTL packet input from the packetizer/depacketizer to the control data monitor in accordance with ITU-T (International Telecommunication Union-Telecommunication standardization sector) Recommendation T.38. The control data monitor repeatedly sends the UDPTL packet on the basis of the notification control signal.
