摘要:
A system for controlling the movement of carriages in a conveyor system is disclosed in which individually powered carriages are controlled so as to stop a carriage at a designated position on the conveyor rail. Electrical contact wires extend along the conveyor rail and are electrically connected to controller units on each of the carriages by electrical contacts sliding along the electrical contact wires. Certain ones of the electrical contact wires have electrical discontinuities which define boundaries of first and second zones. The electrical discontinuities form a normally open electrical circuit with the controller units of each of the carriages, thereby keeping such controller units in the inoperative or "off" position. In this position of the controller unit, the power unit of each of the individual carriages drives the carriage along the conveyor rail. When the electrical circuit of the electrical contact wires is completed in a first zone, such as by the presence of a stopped carriage or other obstruction, the controller unit of a carriage entering the adjacent second zone will be actuated by this completed electrical circuit and will stop the carriage before it encounters the stopped carriage or other obstruction.

Provided is a construction machine. The construction machine is provided with a lower propelling body and an upper slewing body. The upper slewing body has an upper frame, a cab disposed on a left portion or a right portion of the upper frame, and cab mounts. The cab mounts are disposed at lateral ends on each of front and rear portions of the cab respectively, including, on at least one of the front and rear portions, first and second outer-side cab mounts disposed at the outer side of lateral ends of the cab. The first and second outer-side cab mounts are juxtaposed with a small enough distance to receive a rollover load concurrently when the construction machine rolls over toward a side of the cab.

A construction machine has a locking mechanism for locking a lower end of a front part of a guard member onto a bracket while allowing a cab to be moved with elastic deformation of an anti-vibration mount. The locking mechanism has a shaft body across the bracket and the guard member vertically movably with the guard member. The shaft body has a stopper to be engaged to an upper frame side to restrict a moving amount of the shaft body to a stroke for shock absorbing. The bracket has a bolt insertion hole for a bolt to fix the bracket and a shaft body insertion hole for the shaft body. The bolt insertion hole is a lateral oblong hole extending in a direction inclined, with respect to the horizontal direction, toward a direction orthogonal to a load acting direction in the lateral rollover.

According to one embodiment, a controller for a storage apparatus is disclosed having interfaces connectable to a host system, a first storage apparatus and a second storage apparatus. A data in the first storage apparatus and a data in the second storage apparatus are duplicates. A status table stores the operating state regarding the first storage apparatus and the second storage apparatus, wherein the operating state indicates among writing, reading, or standing by. A monitor monitors the interfaces and set up the operating state into the status table. A buffer memory buffers the data for writing in the first storage apparatus and the second storage apparatus. A command response unit receives the data for writing and write-in request from a host system, and directs the writing of the data to the first storage apparatus and the second storage apparatus while making the buffer memory buffer the received data.

A controller is connectable to a host system and a plurality of storage devices. A monitor unit monitors operating status of a plurality of storage devices and sets the operating status of the storage devices in a status table. Upon receiving a write command from the host system, a command responding unit receives write data sent from the host system within a certain period of time after the write command, holds the write data received in a buffer memory, instructs a timer to start counting, sets a write destination for data in the status table, outputs a control signal that gives an instruction to write data to the storage device of the write destination, and returns a write completion response corresponding to the write command to the host system when receiving the deadline notification from the timer.

According to an embodiment of the present invention, a mobile communication system comprises a plurality of cellular stations configured to each form areas and a control device configured to connect the cellular stations to a network through communication resources. The control device comprises a construct processing module, a prediction processing module, a secure processing module and an establishment processing module. The construct processing module constructs a database storing hand-off records in time series of a plurality of the mobile terminals. The prediction processing module predicts one or more candidates of cellular stations of connection destinations next to the mobile terminals with reference to the time series of the database before hand-offs are requested. The secure processing module secures channels in the communication resources of the predicted candidates. The establishment processing module establishes communication links via the secured channels among the mobile terminals and the network when hand-off execution is requested.

According to this invention, there is provided a method applicable to the system which comprises a plurality of base stations each forming radio zones and storing a mobile terminal, and a gateway being connected to a packet communication network and relaying packet communication between the packet communication network and the mobile terminal. The method comprises buffering packets transmitted by a downlink to the mobile terminal in a packet buffer, requiring retransmission of unarrived packets in handover accompanied by movement among the radio zones, reading the packet required from the mobile terminal to retransmit the packet to the mobile terminal that is a request source, and assigning serial identification numbers to packets at least in a start to an end of the handover. When the identification numbers of the reached packets are discontinuous, the mobile terminal requires retransmission of packets needed to eliminate the discontinuity.

According to one embodiment, a mobile communication system includes base stations each forming a wireless zone for wirelessly accommodating mobile terminals, and a control device accommodating the base stations. The control device includes a construction module, a prediction module and an instruction module. The construction module constructs a database regarding a history of handovers by the mobile terminals. The prediction module predicts a base station of the next connection destination of a mobile terminal being in communication and timing of a handover to the base station of the next connection destination on the basis of the database. The instruction module instructs the handover to the predicted base station to the mobile terminal being in communication before the timing comes.

A travel mode setting device for a hybrid car capable of ensuring the security against car theft and convenience when the car is lent to the third party. The hybrid car has travel drive sources and selectively uses one of them and can travel in one of travel modes. Authenticating means separately authenticate the car user and creates authentication results. Limiting means limits the travel modes to the usable travel modes according to the results of the authentication by the authenticating means.
