Title: A pressure regulator
Inventor: KAY FRANCIS XAVIER
IPC: A62B9/02
Filed: 2002-05-14
Granted: 2005-11-03
Abstract: A pressure regulator suitable for use as a breathing demand valve in self-contained breathing equipment comprising a first chamber (31) incorporating an inlet port (29,30) having an inlet valve (36) therein, preferably in the form of a poppet valve and biased so as to seal of the inlet port, and separated from a second chamber by a diaphragm (6). The diaphragm co-operates with the end of a stem (3) extending from the poppet valve member (36) of the inlet valve such that, upon inhalation by the user, the diaphragm (6) is deflected towards the inlet valve and exerts a force on the poppet valve stem sufficient to open the poppet valve and, upon exhalation by the user, the diaphragm (6) is deflected away form the inlet valve so that the diaphragm no longer contacts the end of the poppet valve stem and the inlet valve closes. A baffle plate (9) is positioned in between the diaphragm and inlet valve so as to prevent, when the inlet valve is open, a portion of the pressurised fluid flow from impinging upon the underside of the diaphragm and tending to close the inlet valve. Optionally, the end of the diaphragm may incorporate an exhaust port to ambient, which, when the inlet valve is opened, is sealed by the end of the poppet valve stem sealably engaging with a valve seat around the exhaust port. <IMAGE>

Filed: 1996-01-30
Granted: 1998-07-30
Abstract: Encoded data is reversely reproduced by decoding each picture only once and using only as many frame memory sections as are needed in a normal playback operation. A picture header detector (34) detects a picture header from data read out from a video code buffer (10) to identify the type of picture. The picture type information controls a picture data selecting circuit (35) for selecting frames of I and P pictures equal in number to the number of frame memory sections in a frame memory bank (16). The selected frames are supplied to an inverse VLC circuit (11) to be decoded, starting at the head of a GOP with an I picture. The decoded I and P pictures are stored in the frame memory bank (16) and transmitted to a display unit (18), starting with the temporally most recent picture and reading backward.

Granted: 2003-04-10
Abstract: There is provided a high-pressure dome type compressor which comprises a motor using a rare earth magnet and has stable performance. There are provided a compression element 3 and a DC motor 5 for driving the compression element 3 in a casing 2. The motor 5 is disposed in a high pressure area 6, which obtains a high temperature and high pressure due to a discharged gas. The motor 5 includes a rare earth/iron/boron permanent magnet having an intrinsic coercive force of 1.7 MA/m<-1> or greater in a rotor and has a rated output or 1.9 kW or higher. An inverter 10 controls a current to be supplied to the motor 5 such that a temperature of the motor 5 becomes equal to a predetermined temperature or lower and that an opposing magnetic field generated in a stator of the motor 5 has a predetermined strength or less. Therefore, since the rare earth magnet of the motor 5 does not obtain a high temperature and is not exposed to a strong opposing magnetic field, the magnet is hardly demagnetized. Thus, performance of the motor 5 and further performance of the high-pressure dome type compressor 1 become stable. <IMAGE>

Abstract: A method of high efficiency generation of ions of desired polarity, which includes the steps of positioning a first electrode at a predetermined spacing from a second electrode having a closed shape configuration, applying to both electrodes a direct voltage of the same polarity, at the same time as applying the direct voltage, applying high voltage pulses to the first electrode only, thereby to cause ion generation in the vicinity of the first electrode and to set up a rapidly moving ion stream from the first to the second electrode along an electrical field therebetween, wherein the duration of the pulses is shorter than the time taken for the ion stream to reach the second electrode, and wherein ions in the ion stream have the same polarity as the second electrode, thereby to be repelled and concentrated as they flow through the second electrode. The method may also include the generation of a stream of ions, with reduced ozone content, which includes the additional step of applying a negative pressure gradient to the ion stream, thereby to deflect ozone generated by the corona discharge to a direction different from that of the flow of ions.
