Abstract: The dynamic pressure bearing device is structured such that the pores of porous material as they are are disposed in the surfaces thereof forming the negative pressure cancel portions 15b and a lubricating fluid is supplied to the negative pressure generating areas thereof through the pores of the negative pressure cancel portions 15b, whereby, even if recess-shaped grooves forming the negative pressure cancel portions 15b are formed shallow in depth and wide in width, or even if such grooves themselves are not formed at all, the dynamic pressure bearing device is able to fulfill its negative pressure cancel function in a sufficient manner. This makes it possible to eliminate the need for provision of the conventional recess-shaped grooves which are formed deep and narrow, thereby eliminating the need to execute an expensive operation such as a cutting operation or the like, so that the negative pressure cancel portions 15b can be formed at a low cost by inexpensive means such as by molding or the like.

Abstract: A light beam scanning device 1 has: a laser unit 4 which is placed at a fixed position; a collimating lens 5 which is placed in front of the laser unit; and a swinging mechanism 6 of the magnetic driving type which laterally swings the collimating lens 5. The rotational angle position of the lens due to the swinging mechanism 6 is detected on the basis of an output of a Hall element 97 which detects the origin of the rotational position of a rotor 92 of the swinging mechanism 6. Based on the detection, the light emitting timing of the laser unit 4 is feedback controlled. The lens 5 is directly swung so as to laterally swing the laser beam. As compared with a device of a prior art which uses a reflector plate or a polygon mirror, the present device can be compactly configured in a miniature size.

Abstract: In a node (14) which is for use in an ATM (asynchronous transfer mode) network and which is supplied with user cells, the node includes a failure detecting section (11) for detecting a failure which is occurred in the ATM network such that no user cell is supplied to the node. The node further includes a band detecting section (12) for detecting, as a detected band, a transmission path band used in transferring the user cells immediately before occurrence of the failure. Connected to the failure detecting section and the band detecting section, a producing section (13) produces, when the failure detecting means detects the failure, OAM (Operation: Administration and Maintenance) cells at a production rate increased within a range such that the detected band is not exceeded. The OAM cells are for use in transferring information indicative of occurrence of the failure.

Abstract: A soldering iron (1) comprises a soldering head (4) connected to a handle (2). A cylindrical catalytic element (20) located in a combustion chamber (8) converts gas to heat for heating a soldering tip (15). An electrode (40) located within the catalytic element (20) initially ignites a fuel gas/air mixture to burn in a flame (42) within the catalytic element (20) for raising the temperature of a downstream portion (50) of the catalytic element (20) to its ignition temperature. Heat from the downstream portion (50) raises an upstream portion (51) of the catalytic element (20) upstream of the flame (42) to its ignition temperature, which then commences to convert the fuel gas/air mixture to heat. This starves the flame (42) of fuel gas/air mixture, thus extinguishing the flame (42) so that the catalytic element (20) continues to convert fuel gas/air mixture to heat in a catalytic reaction.

Abstract: A digital/analog TV common-use receiver having a single ghost canceler, and a ghost cancellation method are provided. The single ghost canceler includes a first filter coefficient generator for generating first filter coefficients using a first reference signal included in the analog TV signal, a second filter coefficient generator for generating second filter coefficients using a second reference signal included in the digital TV signal, and a digital filter for filtering the analog TV signal using the first filter coefficients if the analog TV signal is received, and the digital TV signal using the second filter coefficients if the digital TV signal is received. Since an equalizer used when receiving a terrestrial digital TV broadcast is also used upon receiving a terrestrial analog TV broadcast, the single equalizer can correspond to both digital and analog TV signals.
