A buried object scanning device includes a capacitance sensor, a search image conversion processing unit, a memory unit, a display unit, an operation input unit, and a display control unit. The capacitance sensor detects a buried object. The search image conversion processing unit converts the detection result of the capacitance sensor into a search image. The memory unit stores search images and a grid layer including grid lines corresponding to a specific scale. The display unit displays the search images and the grid layer. The display control unit controls the display unit to display the search image superimposed with the grid layer and to display the search image in a state of being movable relative to the grid layer, in response to input to the operation input unit.

Buried object scanning device, display control method for buried object scanning device, and display control program

A switch according to one or more embodiments may include a movable unit movable in response to an operation. A drive unit is drivable in response to movement of the movable unit. The switch may include an operation-linked unit movable in response to the movement of the movable unit and an operation follower unit spaced from the operation-linked unit to move in response to movement of the operation-linked unit with a magnetic force between the operation follower unit and the operation-linked unit. At least one of the operation-linked unit or the operation follower unit is magnetic. The drive unit is drivable in response to movement of the operation follower unit. The operation follower unit accommodated in a chamber is spaced from the operation-linked unit.

Switch

A trigger switch according to one or more embodiments may include a first conductive plate (movable electrode) movable in response to movement of a trigger receiving a depressing operation, and a second fixed electrode (fixed electrode) located adjacent to a movable range of the first conductive plate with a space in between. The second fixed electrode forms a capacitor together with the first conductive plate. The capacitor formed by the first conductive plate and the second fixed electrode has a capacitance that changes as the first conductive plate moves.

Trigger switch

A motor control device configured to control a motor, includes a first memory; a second memory different from the first memory; a communication interface circuit configured to receive a control command from an external device; a command parser configured to store control information in the first memory and in the second memory when the control command includes control information defining an operation of the motor, and to generate a response signal including the control information stored in the first memory when the control command includes a command for verifying a communication state and transmit the response signal to the external device via the communication interface circuit; a control unit configured to read the control information from the second memory; and a drive signal generator.

Motor control device and game machine

In a motor control device, a communication interface receives a control command defining a target rotation amount and a target rotation speed of a motor. A sensor interface receives a detection signal from a rotation angle sensor outputting a detection signal in every rotation of the motor at a predetermined angle. A controller decides a set value of a rotation speed of the motor. A drive signal generator generates and outputs a drive signal for rotating the motor. The controller calculates a difference between the target rotation amount and a total rotation amount of the motor from start of execution of the control command, based on the number of received detection signals, and determines whether an abnormality occurs in operation of the motor based on an update frequency of a minimum value of the difference or a non-update period when the minimum value of the difference is not updated.

A motor control device includes: a communication interface receiving from an external device a control command for defining a target rotation amount and a target rotation speed of the motor; a sensor interface connected with a first rotation angle sensor outputting a first detection signal in every rotation of the motor at a first angle or a second rotation angle sensor outputting a second detection signal in every rotation of the motor at a second angle larger than the first angle; a controller obtaining a measured value of a rotation speed of the motor based on a reception interval of the first or second detection signal, to decide a set value of the rotation speed to bring the measured value close to the target rotation speed; and a drive signal generator generating a drive signal for rotating the motor according to the set value, and outputting the drive signal.
