Title: Condensate traps.
Inventor: RICKETTS ANTHONY GRAHAM
IPC: F16T1/48
Filed: 1991-06-03
Abstract: A condensate trap comprises a valve (10) disposed within a casing (4), and a sensor unit (18) for monitoring the performance of the valve. The sensor unit comprises a downwardly directed passage (16) having an inlet (14) at its upper end, and a sensor element (26) at its lower region. An upper region of the passage (16) has an outlet port (30) which communicates with the valve (10). There is a square tube (34) fitted coaxially within the passage. The corners of the tube contact the wall of the passage, leaving flow passageways between the faces of the tube and the wall of the passage. These flow passageways communicate with the interior of the tube at both ends of the tube. When the valve (10) is open, condensate in the passage (16) can flow to the outlet around the bottom of the tube (34) and up the passageways between the tube (34) and the wall of the passage (16). When the valve (10) is closed, the pressures at the inlet (14) and the outlet post (30) can be equalised by flow through gaps between the top end of the tube (34) and the wall of the passage. If the valve does not close properly and a large leakage occurs, condensate will be forced out through the valve and the level will fall to expose the sensor which will react to provide an alarm signal. <IMAGE>

Title: Anti-disaster monitoring system
Inventor: KIKUCHI MASAMICHI
IPC: G08B26/00
Filed: 1991-08-28
Abstract: An anti-disaster system in which terminals are called by the polling system and in which the response signals from the terminals are received and decoded by a receiver to issue an alarm. Each of the terminals transmits an interrupt signal at a predetermined time during the receivers transmission of the calling signal when an abnormality is detected. The receiver responds to the interrupt to perform group calling (followed by calling of sub-groups and/or individual terminals within the relevant group) to specify the terminal in which abnormality data is detected. The receiver transmits a calling signal for interrupt confirmation to the terminals when it receives the interrupt, to allow the terminal to transmit an interrupt response signal which indicates the cause of generation of the interrupt. The receiver transmits the calling signals in a voltage mode, and the terminals transmit the terminal response signals in a current mode. <IMAGE>

Title: Motion compensated digital video signal processing
Inventor: GILLARD CLIVE HENRY
IPC: H04N7/01
Filed: 1991-12-20
Abstract: An input digital video signal representing a series of input frames (IP1 to IP4) is processed to produce an output digital video signal representing a series of output frames (OP1 to OP4) with an increased motion blur effect. For each output frame at least one intermediate field or frame (e.g. IM2a) is produced by motion compensated temporal interpolation between a pair of the input frames (IP1, IP2). Each output frame (OP2) is then produced by combining the intermediate field or frame (IM2a) with at least one further intermediate field or frame (IM2) and/or with one of the respective input frames (IP2) so that the output frame has an increased motion blur characteristic compared with that of the input frames. Using motion compensated temporal interpolation, a change in frame rate can also be produced as between the input frames and the output frames. <IMAGE>

Title: Chemical vapor phase growth of silicides in the presence of water
Inventor: MIFUNE AKITO
IPC: C23C16/42
Filed: 1992-11-12
Abstract: A chemical vapor phase growth method for depositing a silicide, such as Wsi2 using a silicon source gas eg silane or disilane and a gaseous heat-resistant metal compound such as tungsten hex-fluoride (WF6) is characterised by supplying water vapor suitably at a partial pressure of 10< &cirf& 8> to 10< &cirf& 9> order of Torr in the process of successively depositing tungsten silicide films on semiconductor substrates of plural batches, whereby the sheet resistance of the tungsten silicide films can be made constant throughout the batches. It is thus possible to solve the problem of a conventional apparatus, i.e., the phenomenon that the sheet resistance of the silicide films increases as the batch number increases. This constant sheet resistance is attained by keeping the thickness of the tungsten silicide films uniform through the processing of all batches. Molybdenum and titanium silicides may also be prepared and the silicide may be deposited on SiO2 or Si3N4 insulating layer. An apparatus for carrying out this process comprises a container in which substrates are installed; source gas supply pipes for respectively supplying a gaseous silicon compound and a gaseous heat-resistant metal compound to said container; and a further supply pipe for supplying water vapour to said container. <IMAGE>
