Abstract: A mobile terminal (10) of the present invention has a sensor (15) for detecting a pulse, in an upper end portion of a back surface of a main body of the mobile terminal (10). The sensor (15) is constituted by a light-emitting element and a light-receiving element. A position of the sensor is determined so that a force acting on the sensor falls within a range from 50 gf to 200 gf in a case where the mobile terminal is supported at its lower end portion and at the sensor by a fingertip. Thus, the present invention provides the mobile terminal (10) which can be always carried with a user and which realizes easy and stable pulse measurement.

Abstract: In a proportional solenoid valve control device, a mode selecting switch has an auto-mode position for sending a control signal from a level converting section to a driving signal amplifying section, a valve fully-closing manual position for supplying a valve fully-closing signal to the driving signal amplifying section, and a valve fully-opening manual position for supplying a valve fully-opening signal to the driving signal amplifying section. With the mode selecting switch set at the valve fully-closing manual position, a value of the valve fully-closing driving signal can be adjusted. With the mode selecting switch set at the valve fully-opening manual position, a value of the valve fully-opening driving signal can be adjusted. This makes it possible to easily perform an initial setting operation of the proportional solenoid valve by a valve controller.

Abstract: A mode selecting switch 53 sets at an auto-mode position for sending a control signal from a level converting section 39 to a driving signal amplifying section 39, a valve fully-closing manual position 53c for supplying a valve fully-closing signal corresponding to a valve fully-closing position of a proportional solenoid valve 10 to the driving signal amplifying section 39, and a valve fully-opening manual position 53b for supplying a valve fully-opening signal corresponding to a valve fully-opening position to the driving signal amplifying section 39. Under a state where the mode selecting switch 53 is switched to the valve fully-closing manual position 53c, a value of the driving signal obtained when the proportional solenoid valve 10 is fully closed is adjusted. Under the mode selecting switch 53 is switched to the valve fully-opening manual position 53b, a value of the driving signal obtained when the proportional solenoid valve 10 is fully opened is adjusted.
