Managing a vehicle body including computing an efficiency value of a monitoring target, the monitoring target being the power train or a part or a subsystem of the power train, on the basis of information about the vehicle body, the information being sensed by a sensor provided to the vehicle body. An output terminal that outputs the efficiency value of the monitoring target. Determining whether a load parameter is larger than a load determination value set in advance, and computing the efficiency value of the monitoring target on the basis of input energy and output energy of the monitoring target on condition that the load parameter be larger than the load determination value, and recording the computed efficiency value of the monitoring target.

Vehicle body management system

The present disclosure provides a work machine management system that can predict the maintenance timing of a work machine with higher accuracy than conventional techniques. A work machine management systemof the present disclosure includes an input/output unitand a processing unit. The input/output unitreceives from work machinespositional information PI and operation information OI on the work machines, and also receives from a geographical information system servergeological information GI on an area where the work machinesare to perform an operation, based on the positional information PI. The processing unitpredicts the maintenance timing of each work machinebased on the operation information OI and the geological information GI. In response to a request from an external portable terminal, the input/output unitoutputs to the portable terminaldata on an alert based on the maintenance timing of the work machinepredicted by the processing unit

Work machine management system and work machine management device

An injector diagnosis deviceincludes: an engine sound model generatorconfigured to generate a normal engine sound model and an abnormal engine sound model based on the number of cylinders of the engine and a combustion pattern of the engine; an operating sound obtainment unitconfigured to obtain the operating sound of the engine operating with the combustion pattern; a frequency characteristics calculation unitconfigured to calculate the frequency characteristics of the operating sound obtained by the operating sound obtainment unitand an injector diagnosis unitconfigured to diagnose whether or not the injectors have a failure based on the frequency characteristics of the operating sound which is calculated by the frequency characteristics calculation unitand the normal engine sound model and the abnormal engine sound model which is generated by the engine sound model generator

Injector diagnosis device and injector diagnosis method

An injector failure diagnostic devicediagnoses injector failures for a multi-cylinder internal combustion enginehaving injectorsto, each injector injects fuel to the corresponding cylinder. The injector failure diagnostic deviceincludes: an operating sound obtainment unitconfigured to obtain current operating sound that is operating sound when all of the injectors operate, and obtain pseudo-failure operating sound sequentially for each of the injectors, the pseudo-failure sound being operating sound generated by stopping the fuel injection from one injector while maintaining the operation of the remaining injectors; and a faulty injector identification unitconfigured to determine whether or not the pseudo-failure operating sound of each injector obtained by the operating sound obtainment unitis similar to the current operating sound to identify a faulty injector.

A printing apparatus includes a printing cylinder () that can hold sheets () and transfer them one by one continuously, first to fourth inkjet heads (-), and a feeder unit (). The printing apparatus includes a speed reducer () that switches the speed of the feeder unit () between single-sided printing and double-sided printing. In single-sided printing, the feeder unit () is driven at a first supply speed at which the sheets () are supplied to the printing cylinder () one by one continuously, and the printing cylinder () is driven at a transfer speed at which the sheets () supplied from the feeder unit () one by one continuously are transferred. In double-sided printing, the printing cylinder () is driven at the transfer speed, and the feeder unit () is driven at a second supply speed that is &#xbd; the first supply speed. The printing apparatus that operates stably in both single-sided printing and double-sided printing can be provided.

[Problem to be Solved] Provided is a computer system that can accurately evaluate data to be analyzed without adding training data. [Solution] The computer system forms, from a matrix based on a co-occurrence frequency of first data elements forming at least one piece of data out of a plurality of data and second data elements appearing in vicinity of the first data elements, vectors for a plurality of data elements as the first data elements, calculates similarities for the first data elements on the basis of the vectors, and sets evaluation values for the first data elements on the basis of evaluation values corrected in accordance with the similarities.

Computer system

A sheet-like member holding device includes a first holding unit disposed between a gripper receiving portion and a side wall of a gap, and configured to hold a base of a non-metal sheet. The first holding unit includes a space in which the base is inserted while the non-metal sheet extends inward in a radial direction from an outer surface side of a printing cylinder, and an abutment wall configured to restrict movement of the base to the outside in the radial direction. An end portion of the space in an axial direction of the printing cylinder is open to the outside. This makes it possible to attach and detach the non-metal sheet by a simple method without moving a gripper member or gripper pad.

Sheet-like member holding device of printing press

A multi-feed detection device includes: an arm member supported swingably and configured to come into contact with a traveling sheet; and detecting means for detecting whether a plurality of the traveling sheets are overlapped and fed, on the basis of swing of the arm member. The detecting means includes: a detection plate attached to an arm; and a non-contact sensor configured to measure, in a non-contact manner, the positional relation between the non-contact sensor and the detection plate, the positional relation being changed by swing of the arm.
