  • Patent number: 11642898
    Abstract: A printer control unit controls a fan, based on an acquired reference temperature and an output of a sensor, to cause a temperature of a platen drum or a temperature of a sheet supported by the platen drum to be the reference temperature. Specifically, at step S100, the printer control unit acquires a type of the printing medium to be used for printing, acquires the reference temperature at step S110, and at step S150, controls an operating state of the fan, based on the temperature of the platen drum output by the sensor, such that the temperature of the platen drum becomes the reference temperature acquired at step S110. As a result, a temperature increase of the platen drum becomes substantially saturated at the targeted reference temperature.

  • Patent number: 11534929
    Abstract: Emergency stop pressure sensors 17 are installed on both side surfaces of a movable link 11 of a robot arm 14 of an assembly robot. When a worker S unintentionally walks in a swing range Ra of the robot arm 14 and contacts the emergency stop pressure sensor 17, a detection signal is transmitted to a control unit 19, and the control unit 19 shuts power transmission to a driving source swinging the robot arm. The emergency stop pressure sensor 17 has a first electrode and a second electrode constituting a pair of electrodes and an intermediate layer formed of rubber or a rubber composition, which is disposed between the pair of electrodes, the intermediate layer generating power upon deformation caused by contact with a contacted body (the worker). A side of the intermediate layer in a laminate direction undergoes surface modification treatment and/or inactivation treatment.
