    摘要： To improve the data compression ratio in the data compression/decompression method utilizing the down-sampling process. Image data in a DS area division unit (130) is divided into a plenty of DS areas and DS areas which are not important are converted into contracted data of the block size by down-sampling in a down-sampling unit (131). A relocation unit (132) allocates two or more contracted data in one DS area, inserts file data into the other portion in the DS area, and removes the DS area where no contracted data is allocated, thereby reducing the entire image size. The image data thus contracted is inputted into a JPEG encoder (14) and subjected to a DCT process and a quantization process for each block. When performing restoration, decompression is performed by the JPEG decoder and the original location is restored. As for the contracted data, interpolation is performed to restore the image data.

    摘要： A speaker system may be desired to acquire a fixed directivity over a frequency range as wide as possible. However, a speaker system using a horn of a fixed directivity is frequently used in combination with a box speaker having a built-in woofer unit. This system is large-sized. Another desire is to acquire the fixed directivity in a lower frequency. The speaker system (10) is provided with an enclosure (20), a first speaker unit (30) for a low range, and a plurality of second speaker units (31, 32 and 33) for a high range. The enclosure (20) has a front plate unit (21) as a baffle plate and a rear plate unit (22). The length of the rear plate unit (22) along a first direction perpendicular to the longitudinal direction is shorter than that of the front plate unit (21) along the first direction. The first speaker unit (30) and the second speaker units (31, 32 and 33) are mounted on the front plate unit (21). The second speaker units (31, 32 and 33) are juxtaposed along the first direction. The second speaker units (31, 32 and 33) have their diaphragms positioned near the front plate unit (21) in the longitudinal direction.

    摘要： The resonance frequency of a magnified-sound space is determined based on a basic amplitude/frequency characteristic obtained by sound magnifying, from a speaker (13) located in the magnified-sound space (40), a predetermined measurement signal and then receiving the sound by use of a microphone (14) located in the magnified-sound space (40); also based on a first amplitude/frequency characteristic obtained by sound magnifying, from the speaker (13), the measurement signal and a first delayed signal, which is obtained by delaying an output signal from the microphone (14) by a first delay time of zero or more, and then receiving the sound by use of the microphone (14); further based on a second amplitude/frequency characteristic obtained by sound magnifying, from the speaker (13), the measurement signal and a second delayed signal, which is obtained by delaying an output signal from the microphone (14) by a second delay time of zero or more, and then receiving the sound by use of the microphone (14). The second delay time is different in value from the first delay time.

    摘要： [PROBLEMS] To downsize a photodetector-mounted apparatus. [MEANS OF SOLVING THE PROBLEMS] A photodiode (6) that generates an electric signal according to light reception onto a light receiving surface (6a) is attached to a small printed board (10). An electromagnetic shield cover (14) formed separately from the photodiode (6) is disposed in front of it, and is mounted on the small printed board (10). The electromagnetic shield cover (14) is provided integrally with a substrate fixing portion (14d) fixed to a substrate (2), and forms a specified angle with respect to the substrate fixing portion (14d). In addition, the substrate fixing portion (14d) is mounted to the substrate (2) while kept in contact with the substrate (2).
