摘要： A frequency converter which is capable of rejecting unnecessary signals generated by image signals. The frequency converter has first and second local oscillation circuits which generate local oscillation signals whose frequencies are the same and whose phases are different by 90 degrees from each other. The converter further includes two mixer circuits, and a hybrid coupler. The mixer circuits generate two unnecessary signals whose phases are different by 90 degrees from each other. The hybrid coupler delays one unnecessary signal by a quarter of a wavelength to generate two unnecessary signals whose phases are different by 180 degrees from each other, so that they are cancelled by each other.

摘要： To make it possible to receive a modulated signal which is obtained by suppressing a carrier signal such as a high definition TV signal which is digitally demodulated such as QAM (quadrature amplitude modulation), a receiver of the double super-heterodyne system having the first and second mixers 9 and 13 is a basic constitution. A band pass filter having a flatness in pass band and a small deviation of group delay which will prevent the demodulation of a high definition TV signal from degradation is used a first intermediate frequency filter 11. An SAW filter is used as a second intermediate frequency filter 16. The third mixer 28 for converting a second intermediate frequency signal to a third intermediate frequency signal in frequency is installed and the frequency of the third intermediate frequency signal to be converted is set to a value lower than the frequency of the second intermediate frequency signal. The demodulator 33 for a high definition TV signal is installed so as to demodulate a high definition TV signal included in the third intermediate frequency signal.

摘要： The present invention has an object to provide a surface treatment apparatus, which can form a high-quality film at a high speed while preventing deterioration of the film due to collisions of charged particles. The surface treatment apparatus (1) of the present invention comprises a casing (2) partitioned to two chambers, that is, a plasma generating chamber (3) provided with plasma generating electrodes (5, 5′) and a substrate processing chamber (4) provided with a substrate supporting table (8). A plasma vent (6) is formed in the electrode (5′) that composes the partition between the chambers (3, 4). A conductive mesh-shaped sheet (9) is disposed in a direction across the plasma between the plasma vent (6) and a substrate (S) on the substrate supporting table (8). The sheet (9), to which a variable bias is applied, captures charged particles in the plasma so that the charged particles can be excluded from the plasma.

摘要： A shutter for a camera capable of opening a shutter sector in a reduced period of time includes a shutter opening formed in a shutter plate, shutter sectors for opening and closing the shutter opening, a drive lever having a drive pin for operating the shutter sectors, and an actuator for driving the drive lever. The drive pin penetrates through-holes formed in the shutter sectors. The through-holes have a size sufficiently large so that the drive lever is driven by the actuator substantially in a no-load state immediately after starting to drive the drive lever so that the shutter sectors are not moved until the drive pin has achieved sufficient acceleration.
