A prediction device that predicts time for a reducing agent accommodated in a container mounted on a work vehicle to freeze includes a remaining amount information acquisition unit configured to acquire remaining amount information indicating a remaining amount of the reducing agent in the container, a wall surface temperature acquisition unit configured to acquire a detection result of a wall surface temperature of the container, a reducing agent temperature acquisition unit configured to acquire a detection result of a temperature of the reducing agent, and a time calculation unit configured to calculate the time for the reducing agent to freeze based on the wall surface temperature, the reducing agent temperature, and the remaining amount information.

Prediction device, prediction method, and work vehicle

A housing device for housing communication circuits and equipment which includes a frame which can receive a plurality of printed boards, each printed board comprising a communication circuit and circuit cables disposed along the frame. A test jack testing the circuit is disposed at the front end of each printed board, and a connector, which is connected to a connector mounted on the frame, disposed at the rear end of the printed board. The test jack includes further includes first and second leads within a molded body, the opening of each jack being disposed at the front side of the printed board so that the insertion direction is parallel with the printed board. The first and second loads are formed so that they contact each other in the neck of the jack, separate from each other at the rear side of the jack, and project out of said molded body. The first lead of the test jack is connected to a circuit formed on the printed board by a pattern printed thereon and the second lead of the test jack is directly connected to one of the circuit cables.

Device for housing communication circuits and equipment

A rack for mounting a communication apparatus. The rack comprises a pair of right and left vertical side frames and a plurality of block-mounting plates for mounting at least one block which houses at least one printed board. The block-mounting plates are rectangular and are longitudinally disposed between the right and left vertical side frames. The at least one block is mounted on the front face of the block-mounting plates. The upper and lower portions of the block-mounting plates are folded frontward so as to form an upper reinforcing rim and a lower reinforcing rim. The right and left vertical side frames have an L-shaped horizontal cross section. The folded edges of the L-shaped right and left vertical side frames are arranged inward so as to face each other. The block-mounting plates have securing members along the left edge and the right edge thereof. The securing members project backward and have an L-shaped horizontal cross section. The folded edges of the L-shaped securing members are arranged inward so as to face each other. The depth of the L-shaped securing members which project behind the block-mounting plates is determined in accordance with the depth of the at least one block to be mounted on the block-mounting plates. The folded edge of each L-shaped securing member is secured to the folded edges of each L-shaped vertical side frame.

Rack structure for mounting a communication apparatus

An electronic device comprising a printed circuit board unit contained in a protective cover, and which also serves as a guide member when the electronic device is inserted into a mounting chassis. The cover is constructed from a member formed in one piece, the member having cover portions and flexible hinge portions for permitting the cover portions to be pivotally moved with respect to each other between open and closed positions of the cover. The printed circuit board unit has a printed circuit board which is integrally formed at respective opposed ends with an electrical connector and a handle, which both project out of the cover. Such construction is simple and inexpensive to manufacture.
