摘要： The invention provides an optical disc apparatus which restricts an operation sound generated from an objective lens driving portion of an optical pickup and has a reduce sound, in an optical disc apparatus, in particular, an optical disc apparatus installing a microphone for recording an external voice therein. Coils (107, 108), a magnet (109) and opposing surfaces of a yoke (110) are respectively arranged at substantially point symmetrical positions with respect to an optical axis (111) of an objective lens (103) in a state in which no electric current is applied, the yoke (110) and a unit base (117) are connected via a spring member (118), and the unit base (117) is mounted to a casing (120). In this case, the spring member (118) is connected at a position (121) forward apart from the objective lens (103) with respect to the yoke (110), and is formed so as to have at least a deformation freedom in a direction of the optical axis of the objective lens (103). The casing (120) is made in a closed structure surrounding a space in which the unit base (117), a lens holder (106), the yoke (110) and the magnet (109) are arranged, except a surface opposing to a disc-like recording medium (104).

摘要： A separation signal generation unit generates a plurality of separation signals which are independent from one another from the mixed signals for one frame which are converted into those in a frequency region. A mask processing unit judges a noise condition of a first separation signal for each frequency bin on the basis of the first separation signal and second separation signals. The mask processing unit further removes a first noise component obtained on the basis of a judgment result on the noise condition from the first separation signal. A noise amount measuring unit measures the amount of noise in the first separation signal. A noise signal selection unit selects a noise signal for each frequency bin on the basis of the amount of noise measured by the noise amount measuring unit. A noise removing unit removes a second noise component from a noise removal signal inputted from the mask processing unit. The noise removing unit outputs the noise removal signal obtained by removing the second noise component as a target signal.

摘要： In an information reproducing apparatus in which a liquid crystal lens element is used for the selection and switching of layers, the instability of servo control during the switching of the layers due to the overlapping of signals from two layers is eliminated and the focal point is shifted onto the correct switched layer. During the switching of the liquid crystal lens, a focus bias is added depending on the direction in which the layers are switched so as to stabilize servo control. Alternatively, the objective lens is held during the switching and after the switching of the liquid crystal lens element, the hold state is released in synchronization with the rotation of the disk.

摘要： There is disclosed a hot gas generator comprising a compressor for supplying compressed air to a combustion chamber, a gas turbine driven by hot gas flowing from the combustion chamber and operatively connected to the compressor by means of a common rotary shaft, a blower for starting the compressor, an air pressure sensor for detecting an inlet pressure of air supplied to the compressor, a flame monitoring sensor for confirming ignition, a valve for controlling fuel gas supply to the combustion chamber, and a control mechanism. The control mechanism is operable to open the valve to a certain extent and actuate an ignition device at the same time upon a predetermined time lapse after blower actuation, to stop the ignition device and open the valve at a predetermined speed at the same time in response to an ignition confirmation signal from the flame monitoring sensor, and to stop the blower in response to a signal from the air pressure sensor indicating that the generator is in self-sustaining operation.
