Abstract: To transfer slurry without a binder smoothly in each transition between a dewatering process, a water squeezing process, and a drying process during formation of the slurry into a sheet-like shape through these processes. A dewatering process unit P1 conveys slurry while removing moisture in the slurry. A water squeezing process unit P2 conveys the resultant slurry while squeezing water from the slurry by rolling the slurry. A drying process unit P3 conveys the resultant slurry while drying the slurry by heating the slurry. The conveyance speed of the slurry in the water squeezing process is lower than the conveyance speed of the slurry in the dewatering process. The conveyance speed of the slurry in the drying process is lower than the conveyance speed of the slurry in the water squeezing process.

Abstract: In the case of this control device (10) for controlling a machine on the basis of multiple machine data acquired from the machine, a monitoring data acquisition instruction unit (12) instructs a vibration collection unit (3) and a sound collection unit (7) to acquire data at arbitrarily settable times, and a storage instruction unit (14) causes the acquired data and/or feature amounts calculated from the data, multiple machine data acquired at the same time as the measurement unit data, and information about the acquisition date/time of the data to be stored into a database (30) in association with one another.

Abstract: Provided is a monitoring device capable of easily ascertaining an abnormality. A monitoring device comprises: an acquisition unit which acquires actual operation data (53a) from a control device which controls an actual machine; a storage unit which stores reference operation data indicating reference operation of the actual machine, first related information and second related information; a timing chart generation unit which generates an actual operation timing chart and a reference operation timing chart, and displays the timing charts on a display device; and a simulation data generation unit which generates simulation data of a reference image and a real image.

Abstract: A fuel cell metal separator is stacked on a membrane electrode assembly to form a power generation cell. The membrane electrode assembly includes an electrolyte membrane and electrodes provided on both sides of the electrolyte membrane, respectively. The fuel cell metal separator includes a bead seal for preventing leakage of a fuel gas, an oxygen-containing gas, or a coolant as fluid. A top of the bead seal is configured to become flat in cross section by application of a compression load to the power generation cell.

Abstract: A temperature control device comprises: an operation amount upper limit setting part that sets an upper limit of an operation amount of a heater; and a temperature change rate comparing part that determines, in every prescribed time period, whether an actual measured change rate of the temperature of a body-to-be-heated with respect to time is outside a prescribed range that includes a target rate of change. The operation amount upper limit setting part sets the upper limit to a preset initial value when operation of the heater is started toward the target temperature, and updates the upper limit, in a period until the temperature of the body-to-be-heated reaches the target temperature, such that the difference between an actual measured temperature and a temperature locus that is represented using the target rate of change becomes smaller when it is determined that the actual measured change rate is outside the prescribed range.
