Abstract: A capacitance detection device includes at least one detection electrode, a shield electrode disposed in close vicinity of the detection electrode, an AC signal source that supplies an AC signal to the shield electrode, a detection circuit that detects capacitance between a physical object in close vicinity of the detection electrode and the detection electrode on the basis of a detection signal output from the detection electrode and the AC signal output from the AC signal source, and a phase adjustment circuit provided between the AC signal source and the shield electrode. The phase adjustment circuit advances the phase of the AC signal output from the AC signal source.

Abstract: A voice output from an i-th audio source apparatus is adjusted with a frequency transfer function Wii(f) set in an i-th noise reduction filter and is output from an i-th speaker. In the noise reduction filter, a frequency transfer function Wii(f) is set in which the sound is made smaller at frequencies where the gain of the frequency transfer function Cim(f) from the SPKi to a user tends to be relatively larger than the gain of the frequency transfer function Cii(f) from the SPKi to the user, and the sound is increased at frequencies where the gain of Cim(f) tends to be relatively smaller than the gain of Cii(f), where m is an integer excluding i from 1 to n.

Abstract: A connection structure includes first and second members disposed facing each other and an elastically deformable damper, where the first and second members are connected via the damper. The damper is made of an elastically deformable material, and includes a cylindrical portion, a flange, a first vibration absorber, and a second vibration absorber. The first member includes a convex support portion and a first contact portion in contact with a first contact surface. The second member includes a concave support portion and a second contact portion in contact with a second contact surface opposite the first contact surface. Each of ribs protrudes radially outward of the cylindrical portion and extends in an axial direction. The ribs are provided alternately on an inner periphery and outer periphery of the cylindrical portion such that positions of the ribs differ from one another in a circumferential direction of the cylindrical portion.

Abstract: When a screen to be displayed on a touch panel display includes no visual content for appreciation, such as a movie, the screen is displayed at a position closer to the user, at which the user can naturally manipulate the screen. When the screen includes a handwritten input acceptance box, the screen is placed at an upper position so that a handwriting input operation by the user is eased. When the screen includes visual content for appreciation, the screen is displayed at a position slightly distant from the user so as to be suitable for viewing the visual content for appreciation. The position suitable for appreciation is set according to the display size and resolution of the visual content, included in the screen, for appreciation.

Abstract: A lens holder driving device includes a first piezoelectric driver configured to move a first lens holder along an optical-axis direction based on the movement of a first piezoelectric element and a second piezoelectric driver configured to move a second lens holder along the optical-axis direction based on the movement of a second piezoelectric element. The first lens holder includes a portion (first left-bearing portion) near a first shaft member and a portion near a second shaft member. The first piezoelectric driver is provided in the first left-bearing portion and contacts the first shaft member. The second lens holder incudes a portion near the first shaft member and a portion (second right-bearing portion) near the second shaft member. The second piezoelectric driver is provided in the second right-bearing portion and contacts the second shaft member.

Abstract: A switch device includes an operation knob on which a sliding operation can be performed in a horizontal direction, a holder member that holds the operation knob and moves in the horizontal direction, a drive member that tilts as the holder member moves in the horizontal direction, a switch that is pressed down by the drive member as the drive member tilts, and a support member that supports the holder member such that the holder member can move in the horizontal direction. The holder member has a base at a center in the horizontal direction and a flange extending outward from the base in the horizontal direction. The support member has an upper wall that restricts a movement of the holder member in a vertical direction by contacting an upper surface of the flange, and a slit between the upper wall and a middle wall lower than the upper wall.
