Abstract: A signal processing device includes detection circuitry and correction circuitry. The detection circuitry includes a first detection unit and a second detection unit. The first detection unit generates at least one detection signal based on an associated one of output signals corresponding to each of at least two directions. The second detection unit has a broader detection range than the first detection unit and generates at least one correction signal based on the associated one of the output signals corresponding to each of the at least two directions. The correction circuitry corrects an associated one of the detection signals corresponding to each of the at least two directions with at least an associated one of the correction signals corresponding to at least one direction, other than one direction subjected to correction, out of the at least two directions.

Abstract: An electroencephalogram electrode includes: a bottom portion on which a connection member is placed, the connection member which is configured to supply a biological signal that is acquired from a subject through conductive gel, to an external apparatus; an annular wall which annularly extends from the bottom portion in a contact direction with respect to the subject; and a plurality of barb members which are disposed in a holding space for the conductive gel that is located inside the annular wall, and which elongate from the bottom portion in the contact direction with respect to the subject.

Abstract: A chain case structure of an engine, wherein, when a chain case is viewed in the crankshaft direction, both side portions of a mount bracket unit in the width direction extend to the left edge portion or the right edge portion of the chain case and the upper edge portion of the chain case, and a fastening portion to an engine main body is provided on the lower portion of the mount bracket portion. A cylinder portion of a hydraulic control valve of a variable valve mechanism is disposed below the fastening portion while the outer peripheral surface of the cylinder portion is mutually coupled to the mount bracket portion. Reinforcement ribs extend downward from the bottom of the mount bracket, across the cylinder portion.

Abstract: Based on the understanding that time-varying characteristics of a tone element, such as an amplitude and pitch, in waveform data acquired through a live performance of a musical instrument include a variation component intended or controllable by a human player and a variation component not intended or non-controllable by the human player, the present invention allows the two components to be adjusted/controlled separately and independently of each other, so as to achieve effective and high-quality control. Discrete variation value train is acquired for at least one particular tone element in original waveform data, and the acquired variation value train is separated, in accordance with a time constant factor, into a “swell” value train of a relatively great time constant and a “fluctuation” value train of a relatively small time constant. The “swell” value train and “fluctuation” value train are variably controlled independently of each other.

Abstract: Rendition style determining apparatus detects at least one of duration of a first note to be performed at a given time point and time interval between the first note and a second note to be performed following the first note, in order to automatically impart music piece data with an appropriate rendition style. Rendition style to be imparted to the music piece data in relation to the given time point is determined on the basis of the detected duration or time interval. Also, the apparatus can readily control the rendition style to be imparted to the music piece data, by appropriately setting/changing rendition style determination conditions, such as reference time lengths. Music piece data is supplied to a determination device, thereby causes the determination device to perform automatic rendition style determination based on the supplied music piece data and then displays the rendition style imparted to the music piece data.

Abstract: An optical recording/reproducing system for optically recording and reproducing an information signal on and from an optical disc (31) to be recorded with a plurality of track turns includes a light source (52); an optical head (45b) carrying an objective lens (62) for directing a light beam from the light source (52) to one of the track turns, and a tracking servo actuator for displacing the light beam within a movable range to perform both track feed and tracking servo operations for one of the track turns; the optical head (45b) being stationary with respect to the optical disc (31) while performing the track feed and tracking save operations by displacing the light beam in a radial direction of the optical disc; and a recording area on the optical disc having a radial distance equal to or smaller than the movable range of the tracking servo actuator.

Abstract: The invention relates to a system for detecting the height fluctuations of a surface on a recording medium in an optical recording or reproducing apparatus. A light source emits a main light beam for recording or reproducing. An optical system, including an objective lens, focuses the main light beam into a spot on the surface. A first reflecting mirror introduces a sublight beam into the peripheral part of the main light beam. The sub-light beam advances in a forward path through the objective lens to be projected onto the recording surface and reflected thereby. The sub-beam returns again through the objective lens along the peripheral part of the main light beam, but on the opposite side from said forward path.
