Abstract: An operation panel for operating a machine tool includes a first display unit for displaying information related to the machine tool, a keyboard, and a plurality of buttons. The button includes a second display unit and a transparent cover. The second display unit displays a first key image indicating a first function and is able to be switched to display a second key image indicating a second function depending on an application screen displayed on the first display unit.

Abstract: A physical quantity sensor includes a detector that outputs a detection signal in response to an input to a device, and a controller that outputs a signal corresponding to the input to the device based on the detection signal. A method for adjusting the physical quantity sensor is performed based on a value of the detection signal in a steady state and a fluctuation of a value of the detection signal within a predetermined duration. The physical quantity sensor has a first threshold for the value of the detection signal for determining presence or absence of the input, and a second threshold for the fluctuation of the value of the detection signal within a predetermined duration for determining presence or absence of the noise in the detection signal.

Abstract: An information apparatus includes a housing, first and second strain detectors, and first and second stress collectors that transmit distortion applied to a side surface of the housing to the first and the second strain detectors, respectively. Upon having the same amount of distortion is applied to the side surface of the housing, the first and strain detectors outputs different values a processing circuit. This information apparatus has a small size and can be accurately controlled.

Abstract: A receiving apparatus includes a receiving section for receiving a broadcast. The apparatus further includes a location detector for detecting the location of the receiving apparatus, a moving direction calculator for calculating a moving direction of the receiving apparatus based on the location detected by the location detector, and a controller for allowing a reproducing section to reproduce a part of or all of the broadcast received by the receiving section selectively based on the moving direction calculated by the moving direction calculator.
