Abstract: A posture recovery apparatus capable of automatically recovering a posture of a work machine is realized. The setting unit (11) sets a safe posture range based on a posture of the work machine before operation. The acquisition unit (12) acquires posture information on the work machine in operation. In a case where, by reference to the posture information, it has been detected that the posture of the work machine in operation has deviated from the safe posture range for a first period, the recovery unit (13) causes the work machine to carry out a recovery operation.

Abstract: An image forming apparatus includes an image forming unit, a fixer, first and second temperature sensors, and storage and control units. The fixer fixes an image formed on the sheet by pressing. The first temperature sensor is disposed away from the image forming unit and the fixer, and measures an ambient temperature. The second temperature sensor is disposed closer to the image forming unit than the first temperature sensor, and measures an ambient temperature. The storage unit stores one or more difference values between first and second temperatures measured by the first and second temperature sensors when a switching condition is satisfied. When a difference between the one or more difference values in the storage unit and a latest difference value is equal to or larger than a threshold, the control unit stores information indicating that a reference value for determining an abnormality is exceeded.

Abstract: According to one embodiment, an image forming apparatus includes an image forming unit, a first temperature sensor, a second temperature sensor, a cooling mechanism, and a controller. The first temperature sensor detects the internal temperature of a machine body where the image forming unit is arranged. The second temperature sensor detects the environmental temperature of the environment where the machine body is placed. The cooling mechanism cools the image forming unit. The controller adjusts the cooling capacity of the cooling mechanism based on the result of comparing the internal temperature detected by the first temperature sensor with a first threshold, and the result of comparing the environmental temperature detected by the second temperature sensor with a second threshold lower than the first threshold.

The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a valve member biasing component that biases the valve member in a valve-closing direction in which the open degree decreases.

The controller increases the pump discharge amount as a target radiator flow rate that is a target of an amount of coolant passing through the radiator increases.
