A gas spring and a method for filling a gas chamber of a gas spring does not require the use of a gas filling valve. Gas spring (5) includes a rod member (20), a cylinder main body (21), a gas filling chamber (22), first and second sealing members (23, 24), a plurality of pin members (25), and a plurality of slots (26). A gas filling implement (30) makes it possible to fill the gas filling chamber (22) with compressed gas in a simple and reliable manner without providing the gas spring (5) with a gas filling valve having a nonreturn valve. Consequently, the entire gas spring (5) is configured symmetrically about the axial center of the rod member (20), and its center of gravity is aligned with the axial center of the rod member (20), making it possible to prevent the gas spring (5) from inducing vibrations in the main shaft.

A method and apparatus for constructing a filter bank designed to split the frequency spectrum of digital signals into plural bands. Specifically, a low-pass analysis filter unit (H0(z)), adapted to pass frequency components of an input signal not higher than a pre-set frequency, is determined by a high-pass analysis filter unit (H1(z)) passing frequency components of the input signal not less than the pre-set frequency and a phase-linear filter unit (f(z)) having phase-linear characteristics. This enables efficient wavelet splitting of the input signal.

A video signal processing method includes the steps of processing an input video signal and outputting an output video signal, detecting a temporal feature from the input video signal, smoothing the temporal feature by filtering and outputting the smoothed temporal feature, and controlling processing performed in the processing step in accordance with the temporal feature smoothed in the smoothing step. In this method, the smoothing step switches a characteristic of the filtering in accordance with the attribute of the input video signal.

An apparatus for suppressing noise of a video signal. The apparatus includes: a difference-signal generation section generating a difference signal being a field or frame difference between the input and the output video signals; a noise compensation-signal generation section generating a noise compensation signal; a noise-compensation signal subtraction section; and a feedback-ratio control section, wherein the feedback-ratio control section includes a signal-level determination section determining a signal level of the difference signal for each area and detecting an abrupt change in an input signal, a count section counting the number of input fields or frames from the time of an abrupt change in a signal level to the subsequent abrupt change, and a feedback-ratio setting section setting a feedback ratio for the area in accordance with a count value, wherein the feedback-ratio setting section sets the feedback ratio such that the ratio gradually increases as the count value increases.

JPEG-2000 data is formatted into RTP packets for transmission through the Internet. A priority field is provided in the format, and a value indicating the importance of a code stream included in a packet is stored therein. A type field indicates a payload type of a JPEG-2000 code stream. An mh_id field is provided as an identifier of a main header of the JPEG-2000 code stream and indicates a change in the main header. An mh_length field indicates the length of the main header and a fragment offset field stores the number of offset bytes from the start of an image of the packet.

The magnetic fixing device comprises a clamping plate having a fixing surface to which a clamping object is fixed and plural magnetic force generation mechanisms. The magnetic force generation mechanisms each comprise a magnetic material member facing the fixing surface, plural permanent magnets arranged around the outer periphery of the magnetic material member, a first Alnico magnet placed on the back of the magnetic material member, and a first coil for switching the polarity of the first Alnico magnet, and can be switched between the absorption state in which the clamping object is adsorbed and the non-absorption state in which the clamping object is not adsorbed. An operation state indication mechanism capable of presenting an indicator indicating that the plural magnetic force generation mechanisms are in the absorption state or in the non-absorption state is provided on the fixing surface or outer periphery of the clamping plate.
