    摘要: A centrifugal fan with a resonant silencer has a centrifugal impeller and an outer housing. The outer housing has an inlet, an outlet and a resonant silencer. An inlet is positioned along an axial direction of the centrifugal impeller. An outlet is positioned along a radial direction of the centrifugal impeller. The resonant silencer, extended from a cut-off, can reduce noise caused by a vortex. The resonant silencer can be I- or L-shaped. The cut-off can be covered by a net filter, which isolates the resonant silencer from the flow motivated by the centrifugal impeller.

    摘要: A heat dissipation device is described. The heat dissipation device is suitable for electrical equipment, and particularly for a notebook computer. The heat dissipation device has a cooling fan and a plurality of heat dissipation fins. The heat dissipation fins are disposed at an outlet of the cooling fan to exhaust heat on the heat dissipation fins with airflow generated by the cooling fan. Each of spaces between the adjacent heat dissipation fins is determined so as to make the airflow velocity uniform. A preferred predetermined space is about C1×1/(V2−1), where V is an original airflow velocity at the adjacent heat dissipation fins and C1 is a coefficient.

    摘要: Mesoporous hexagonal, cubic, lamellar, wormhole, or cellular foam aluminosilicates, gallosilicates and titanosilicates derived from protozeolitic seeds using an ionic structure directing agent are described. The silicon and aluminum, gallium or titanium centers in the structures are stable so that the framework of the structure does not collapse when heated in the presence of water or water vapor (steam). The steam stable compositions can be used as catalysts for hydrocarbon conversions, including the fluidized bed catalytic cracking and the hydrocracking of petroleum oils, and other reactions of organic compounds.

    摘要: A picture information conversion method and apparatus in which, if the compressed picture information with a variable or non-recognized information volume is input, optimum compression processing on the compressed picture information is performed to prevent underflow and/or overflow to suppress deterioration of the picture quality. A compressed information analysis device 3 analyzes the structure of the picture type of the GOP of the compressed picture information input to the FF buffer 2. A bit allocation device 5 generates a pseudo GOP of the input compressed picture information, based on N frames stored in the FF buffer 2 and on the analysis result information stored in the information buffer 4, and allocates a pre-set code volume to respective pictures of the generated GOP so that the output compressed picture information will be at a second bitrate.
