摘要:
A controlling device for a hydraulically operated cooling fan capable of obtaining optimum cooling efficiency by continuously controlling a rotational frequency of the cooling fan according to a cooling water temperature, a hydraulic oil temperature, and an engine speed is provided. To this end, the controlling device includes a hydraulic motor (16) for driving a cooling fan (13), a variable displacement hydraulic pump (14) capable of controlling the rotational frequency of the hydraulic motor (16), a cooling water temperature sensor (21) for detecting a cooling water temperature (TW), a hydraulic oil temperature sensor (22) for detecting a hydraulic oil temperature (To), an engine speed sensor (23) for detecting an engine speed (E), and a controller (20) which inputs detected signals from these sensors (21, 22, 23), computes and outputs a discharge capacity command value of the variable displacement hydraulic pump (14) according to the inputted cooling water temperature (Tw), hydraulic oil temperature (To), and engine speed (E), and continuously controls a rotational frequency (N) of the cooling fan (13) by means of the variable displacement hydraulic pump (14).

An engine cover 17 has a cover main body 19 and an engine hood 20 which is attached to an opening portion formed on an upper surface of the cover main body 19 and a plurality of reinforcing plates 24 are fixed to an inner surface of the engine hood 20. First to fourth reinforcing plates 24a to 24d of a plurality of reinforcing plates 24 define a space in an engine portion 14. An expansion chamber 26 which is communicated with an intake passage 23 reaching to an engine and resonant chambers 27, 28 which are communicated with the expansion chamber 26 via ports 29 are formed in the engine portion 14.

A printing system, including a plurality of printers, a print data generation section for generating print data printable by one or a plurality of the printers, and a decision section for deciding, based on information concerning printing functions of each of the plurality of printers, whether to generate shared print data printable by a plurality of printing functions or to generate dedicated print data printable by a single printing function, wherein the print data generation section generates the shared print data or the dedicated print data based on a result of the decision made by the decision section.
摘要:
A printing data generating unit designates a first section (page numbers, etc.) corresponding to a change target part of a before-being-changed document and a second section corresponding to printing data of a changed part. A printing unit includes a replacement processing portion. The replacement processing portion determines whether or not the section of the counted number of sheets of paper matches the first section, and when they match, instructs the printing unit to print the printing data of the changed part corresponding to the second section, and when they do not match, causes the before-being-changed document to be discharged directly from the printing unit, and thereby replacing just the first section of the before-being-changed document with a document of the changed part corresponding to the second section.

摘要:
When a request for acquiring image correction data is issued, as is periodically done by a communication terminal, a printing device transmits the image correction data, if the state of the printing device is in a normal mode or in a first energy saving mode. If the acquisition of the image correction data as is periodically done by the communication terminal fails, the printing device transmits the image correction data to the communication terminal at the time when the communication terminal creates print data.
