Abstract: The bacteria detection device includes a reservoir which stores a bacterial solution containing bacteria, a sensor which is provided on a bottom of the reservoir and configured to detect the bacteria in the bacterial solution stored in the reservoir, and a filter which is placed on a liquid surface of the bacterial solution stored in the reservoir to permeate the bacterial solution. The filter increases the concentration of the bacteria in the bacterial solution present in a detection region of the sensor by permeating the bacterial solution.

Abstract: It is made possible to perform power reduction control during non-operation of control levers, and suppress power consumption of a power source when a control lever is moved by an erroneous operation, and thus reduce energy consumption. Accordingly, a controller 50 performs the power reduction control when a non-operation time exceeds a set time after a transition is made from a state in which at least one control lever is operated to a non-operation state in which none of the control levers is operated, and the controller 50 cancels the power reduction control when at least one control lever is operated in a state in which the power reduction control is performed.

Abstract: A controller calculates the ratio between the sum of estimated demanded powers of a plurality of first actuators and the sum of estimated demanded powers of a plurality of second actuators, and calculates, on the basis of the ratio, first and second command values for adjusting allocation between a first allowable torque of a first pump and a second allowable torque of a second pump, and first and second regulators adjust the first and second allowable torques, on the basis of first and second output pressures of first and second torque control valves, such that the first and second allowable torques become values to which a predetermined allowable torque is allocated according to the ratio described above, and control the delivery flow rates of the first and second pumps such that the respective consumed torques of the first and second pumps do not become larger than the first and second allowable torques.

Abstract: A microorganism test method includes: covering, with a hydrophobic capping solvent, a sample containing a specimen and a liquid culture medium, within a region in a vicinity of a sensor configured to detect a microorganism contained in the specimen; and calculating, based on an output from the sensor, information indicating a degree of growth of the microorganism contained in the specimen. For example, an analysis unit drives an array sensor in which many resonators are arranged in a matrix pattern, stores a resonance frequency of a resonator which is acquired at the time of starting the measurement as an initial frequency, and calculates a difference (frequency shift) between the initial frequency and a resonance frequency of the resonator which is measured at predetermined time intervals as information indicating a degree of growth of the microorganism contained in the specimen.

Abstract: It is made possible to perform power reduction control during non-operation of control levers, suppress a return to a normal power state when a control lever is accidentally moved, and make a smooth transition to an operation desired to be performed when a return is made to the normal power state. To this end, in a power reduction state, when a first cancellation condition in which two or more control levers are inclined simultaneously is satisfied or when a second cancellation condition in which one lever continues to be inclined is satisfied, a controller 50 determines that an operator “has an intention of canceling power reduction” and cancels power reduction control.

Abstract: In a hydraulic drive system used for an electrically driven hydraulic work machine that drives a hydraulic pump by an electric motor and supplies a hydraulic fluid to plural actuators to carry out work, the power consumption of the hydraulic pump is kept from exceeding a value decided in advance. For this purpose, a controller calculates target power to be consumed by the hydraulic pump on the basis of the capacity of the hydraulic pump, the delivery pressure of the hydraulic pump sensed by a pressure sensor, and a target revolution speed of the electric motor, and limits the target revolution speed of the electric motor in such a manner that the target power falls within a range of the maximum allowable power.
