Abstract: In one embodiment, a power converter system includes a switching circuitry having a plurality of switches operable to be turned on and off to cause current to flow to deliver power to a load. A driver circuitry is responsive to an oscillation signal and generates control signals for turning on and off the switches in the switching circuitry. A free-running oscillator circuitry provides the oscillation signal to the driver circuitry. The free-running oscillator circuitry has an operational amplifier. A frequency of the oscillation signal will be higher if the operational amplifier outputs a first value, and the frequency of the oscillation signal will be lower if the operational amplifier outputs a second value.

Abstract: An assembling apparatus (manufacturing apparatus) can assemble an actuator (product) in which a shape memory alloy (SMA) is stretched. In the assembly, the SMA is locked by a first holder, a guide is moved along predetermined movement directions while sending the SMA and, after that, the SMA is locked by a second holder. A switch is turned on to pass current from a current source to the SMA via an electrode. The SMA is fixed to two electrodes by caulking members and, after that, an unnecessary portion of the SMA is cut. In such a manner, the actuator is manufactured. Since the SMA is tensioned while current is passed to the SMA as described above, the stretch can be stably performed while suppressing elongation of the SMA. As a result, a product can be manufactured with high quality.

Abstract: A printer divides an input image into a plurality of blocks and extracts a block image corresponding to each of the blocks. The colors of the block image are reduced to, for example, four colors. Index numbers are given to pixels of the color-reduced image, and the four colors are assigned. To a color palette in which color information of the four colors is described in correspondence with the index numbers, object information indicative of the kinds of images (for example, a character, a chart, and a photographic image) is added. Consequently, the handling performance of object information for use in an image processing such as a color conversion process is improved.

Abstract: An image display apparatus capable of displaying an image on a plane of projection by beam raster scanning associated with resonant oscillation in a horizontal scanning direction (the main scanning direction), includes a resonance-point detector for detecting a mechanical resonant frequency in the horizontal scanning direction. Out of frequencies that are multiples of a vertical synchronizing frequency in image display, for example a frequency nearest to the mechanical resonant frequency detected in the resonance-point detector is determined as a horizontal scanning frequency of the raster scanning. The image display apparatus can thus provide a stable image display with ease.

The magnetic recording head has a reflecting converging element with a surface emitting laser incorporated therein, and a transparent plate serving as a slider. A laser beam emitted from the surface emitting laser is reflected by a mirror surface of the reflecting converging element and is converged on a plasmon probe formed on a bottom surface of the transparent plate. Thereby, near-field light effuses from the plasmon probe into a very small area and heats the magnetic bit of the magnetic disk.
