Abstract: An RF circuit (131–138) satisfies Pnoise+NF+G?Plim+sW (0?s?4) at an edge of a guard band with respect to a required transmission level PAll, an upper tolerance level of out-of-band noise Plim, a guard bandwidth W, and a noise level Pnoise, where NF is a noise figure and G is a gain. An IF circuit (121–123) satisfies PAll?Pin+G, where PIF is an output level of a BPF (123). Out-of-band noise levels are reduced to Pnoise by the steep BPF (123). The RF circuit (131–138) is structured so that noise from a local oscillator circuit (134) does not surpass noise from the IF circuit (121–123). Reductions in power consumption are thus realized in addition to guard bandwidth reductions, because of being able to eliminate out-of-band noise from an amplifier (138) using a low-loss filter (140) having an attenuation slope s.

Abstract: The folding communication terminal of the present invention is composed of a display device which is visible to the user when the folding communication terminal is in a folded state, and which is capable of multicolor display. The user knows by glancing at the illumination color, without reading characters displayed on the display device and without straining their eyes, whether a caller's telephone number is notified or not. Furthermore, the display is illuminated in a color which is specified and registered in advance in correspondence with the caller's telephone number. The user is thus able to know at a glance who a call is from. Furthermore, the display device is illuminated in a color distinguishing between whether there is notification information which is yet to be displayed or not. The user can judge whether it is necessary to check notification information with a glance at the illumination color.

Abstract: An image signal processing apparatus includes two JPEG codecs. A plurality of frames of image signals periodically input from a multiplexer are individually compressed by the two JPEG codecs, and the compressed image signals are recorded on a hard disk by an HDD. Furthermore, the plurality of frames of the compressed image signals reproduced from the hard disk are individually expanded by the two JPEG codecs, and the expanded image signals are output to a monitor. Herein, each of the JPEG codecs selectively executes individual compression of the plurality of frames of the image signals and individual expansion of the plurality of frames of the compressed image signals. A CPU makes the JPEG codecs perform the compression process prior to the expansion process.

Abstract: Image data of a target pixel and peripheral pixels are stored in a memory. Using a most significant bit extractor circuit, 4 most significant bits of data are extracted from each image data. A histogram circuit generates a histogram of the extracted 4-bit data. Referring to the histogram, a data processor circuit (17) replaces the image data of the target pixel with a maximum value of the numbers of pixels having the same level and outputs the processed data. Then, a digit-complementing circuit converts the data output from the data processor circuit to 8-bit data and outputs the converted data. In this manner, a regular image is converted into an image similar to a draft-design image.

Abstract: A double-side light receiving solar cell in a planer regular hexagon shape and having first electrodes on both surfaces are divided into four pieces by a line A-A? connecting two opposing apexes and by a line B-B? perpendicular to the line A-A? and connecting center points on two opposing sides. By matching oblique lines of two divided pieces without misalignment and with respective surfaces in an inversed state, the first electrodes on the same side of the two divided pieces align along the same single straight line. Then, the first electrodes that are on the same side are connected with a first inter connecter, thereby constructing a unit having a rectangular outline. Units thus constructed are arranged so that relevant sides match without misalignment. By handling on a unit basis as described above, it is possible to facilitate an arrangement of the cells and an electricity connection work.
