摘要： In the adaptive control apparatus, a computation unit computes weighting coefficients, using a first adaptive control method in a proportion α of a first computation amount, where the first adaptive control method has a first convergence rate and a first convergence error. Further, a computation unit computes weighting coefficients from initial values of the weighting coefficients computed by the computation unit, using a second adaptive control method in a proportion (1−α) of a second computation amount, where the second adaptive control method has a second convergence rate slower than the first convergence rate and a second convergence error smaller than the first convergence error. A controller controls determination of a ratio α/(1-α) based on a moving speed of a mobile unit, and controls the computation units to perform computing processes.

摘要： The invention aims to reduce the size of a disk clamp mechanism to be built into a disk player. The clamp mechanism comprises: a disk clamp portion formed integrally with a turntable; a clamper; and a clamper holder for holding the clamper via a clamper mounting shaft adapted to hold the clamper in rotatable fashion, wherein a flange portion provided at an end of the clamper mounting shaft is placed within a space formed inside the clamper. The clamper comprises a peripheral portion and a chamber portion in which the space is formed, and the disk clamp portion has a recessed groove portion engageable with the chamber portion, the structure being such that, when the disk is clamped, the end portion of the chamber portion is accommodated into the disk clamp portion, thus achieving a size reduction by reducing the height in a direction perpendicular to the disk.

摘要： An adaptive antenna apparatus includes two antenna elements and a parasitic element to which a variable reactance element is connected, and selects an adaptive control processing according to detected signal quality. A controller executes a first adaptive control processing for adaptively controlling respective received signals received by the respective antenna elements and outputting the respective received signals after the adaptive control as a combined received signal, and executes a second adaptive control processing for reactance controlling an element value of the variable reactance element. The controller executes the first adaptive control processing. The controller executes a communication processing when the detected signal quality is equal to or larger than a predetermined threshold. The controller executes the second adaptive control processing when the detected signal quality is not equal to or larger than the threshold.

摘要： A small-sized mobile radio has a built-in antenna is high enough to enhance the antenna characteristics. In the mobile radio, a base plate is structured by a section (antenna-housing section) including a supply portion and a short-circuiting portion, for example, of an antenna element which affect the antenna characteristics, and a section (circuit-housing section) which is the rest of the base plate. The antenna-housing section is so positioned so as to keep the built-in antenna high enough, that is, to keep the space between the base plate and the antenna element large enough. On the other hand, the circuit-housing section is positioned toward the back of the cabinet to provide room for a display and a key section.

摘要： An electromagnetic wave measuring apparatus includes a loop probe section having loop probes whose loop planes are placed so as to be perpendicular to each other, and each loop probe is placed so that its magnetic field detection space is not interfered with by other loop probes. If the loop probe section is placed at measurement position coordinates xi, yj, it detects a magnetic field component at the measurement position coordinates xi, yj, which is parallel to an XY plane, and a magnetic field component in a Z-axis direction at measurement position coordinates xi, yj−1, and repeats measurement by pitch p in a positive Y-axis direction. By calculating the root sum square of the detection results at each measurement position coordinate, a three-dimensional magnetic field level of an object to be measured can be obtained at each measurement position coordinate as electromagnetic field distribution with high-precision.
