Abstract: A vacuum cleaner is disclosed, and this cleaner maintains sucking power at a high level while it resists lowering the suction force although it sucks dust. The vacuum cleaner includes a cylindrical dust collecting case which takes air in sucked by an electric air blower and including dust. The case includes a suction port through which the air including dust flows into the case along a tangent line, and a dust collector communicates with the port. A dust filter in the case is placed in an air-duct through which the case communicates with the electric air blower. This structure allows whirling airflow in the case to whirl continuously in the case, so that dust can be removed from the filter even if the dust attaches to the filter. As a result, sucking airflow can be always secured.

Abstract: An amplifier (10) comprises a digitally clocked automatic gain control loop (11, 12, 13, 14). A Pseudo random clock generator (14) generates the clock signals for the loop. The application introduces a scheme which reduces sidebands caused by digital gain control loops. The effect of gain control on a system can be seen as amplitude modulation on the signal whose amplitude is controlled. This amplitude modulation causes the same sidebands that are commonly seen with AM modulation. This invention introduces a novel method that alleviates AM sidebands for a digitally controlled gain control loop.

Abstract: Provided are a radio communication terminal and a radio communication base station device which are installed in a Multi-User MIMO system even if the ability to suppress interference is low. According to beam combination information fed back from NON-MIMO UE, and beam information and a CQI fed back from another MIMO UE, a scheduler section (102) allocates a space resource to the NON-MIMO UE and allocates the remaining resource to the another MIMO UE. According to the beam combination information, a beam weight generating section (104) generates weight. A transmission beam forming section (105) multiplies each stream outputted from modulation sections (103-1, 103-2) by the weight to form a transmission beam.

Abstract: In a method of driving an AC plasma display panel of the present invention, one field period is made of a plurality of sub-fields (SFs), each including an initializing period, writing period, and sustaining period, and a part of sustaining operation in the sustaining period in at least one of the plurality of SFs and a part of selective initializing operation in the initializing period in a SF following the at least one SF are performed at the same time. The method comprises making a pulse width of a top sustain pulse in one of the sustaining periods in the plurality of SFs different from that in another of the sustaining periods therein. This method limits the SFs in which any erroneous discharge occurs to lower order of SFs and can inhibit the brightness of the erroneous discharge.
