Abstract: An operation system includes: an operation device manually operated by a user and inputting a command of an operation content to a command target apparatus selected from multiple apparatuses; a selection device selecting one apparatus as the command target apparatus according to multiple visual line regions individually set in relation to the apparatuses and a visual line direction of the user detected by a visual line detection sensor, the one device relating to one visual line region disposed in the visual line direction; and a selection maintaining device maintaining a selection state of the command target apparatus even when the visual line direction is changed to another direction pointing to none of the visual line regions while the command target apparatus is selected.

Abstract: An operation system includes: an operation device that is manually operated by a user and inputs a command of an action content to a command target apparatus selected from a plurality of apparatuses; a plurality of display units that are individually arranged on the plurality of apparatuses and display information corresponding to the action content; and a selection device that selects one of the plurality of apparatuses as the command target apparatus according to a visual line direction of a user detected by a visual line detection sensor, the one of the plurality of apparatuses corresponding to one of the display units disposed in the visual line direction.

Abstract: An operation system includes: an operation device manually operated by a user; a control device that controls actions of a plurality of apparatuses according to a visual line direction of the user detected by a visual line detection sensor and an operation content of the operation device; and a contact detection device that detects that the user touches the operation device. The control device enables the visual line direction detected by the visual line detection sensor and reflects the visual line direction in a control of the control device when the contact detection device detects that the user touches the operation device.

Abstract: A tubing pump for transferring a fluid in a detachably attached tube 30 by a pump mechanism 50, the tubing pump is equipped with: a pump body 10 having a base 11 to and from which the tube 30 can be attached and detached; a door 20 pivotally supported to be rotatable with respect to the pump body 10, so as to open or close the base 11; switching urging unit A for urging the door 20 in an opening direction in a first rotation range R1 on a completely opened side and switching an urging direction to a closing direction in a second rotation range R2 on a completely closed side; and closing suppression unit B for suppressing an urging force in the closing direction by the switching urging unit A in the second rotation range R2.

Abstract: An optical disk apparatus comprises a controller that outputs a rotation control signal to rotate an optical disk medium rotating motor in a predetermined direction to a drive section that drives the rotating motor; and a determining section that determines whether the rotation control signal has been continuously output for a first predetermined period of time based on information that has been read out from an optical disk medium when the optical disk medium is being rotated by the optical disk medium rotating motor, wherein when the determining section determines that the rotation control signal has been continuously output for the first predetermined period of time, the controller stops the rotation control signal from being output for a second predetermined period of time on the basis of the determining result of the determining section.

Abstract: A digital filter apparatus into which a digital input signal of plural bits is inputted in each predetermined period and which outputs a digital output signal that is a result of filter-processing the digital input signal in accordance with a predetermined filter coefficient and filter order. The digital filter apparatus comprises a delay processing unit to sequentially delay the digital input signal and/or the digital output signal in said each period in accordance with the filter order; a filter coefficient processing unit to shift down, by an equal number of bits to the absolute value of an exponent represented by a position of “1” in a decimal portion of the filter coefficient that becomes a finite decimal when expressed in binary notation, each of the digital input signal and delayed signals processed by the delay processing unit; and an addition processing unit that adds the signals processed by the filter coefficient processing unit and outputs the adding result as the digital output signal.

Abstract: An optical disk apparatus comprises a speed detector that detects the speed of an optical pickup when the optical pickup moves from a first track to a second track of an optical disk medium, a level variable unit that makes variable the level of an objective lens-use pulse in accordance with the detection result of the speed detector, a drive unit that changes the opposing position of the objective lens with respect to the radial direction of the optical disk medium in accordance with the level of the objective lens-use pulse.
