Title: Method and apparatus for control of constant margin angle in thyristor ac-dc converter
Inventor: FUJII TOSHIYUKI
IPC: H02M7/155
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the failure of a commutation operation even when the frequency of an AC system is changed by a method in which a desired margin angle is changed by using a specific expression so as to be porportional to the frequency of the AC system. SOLUTION: An apparatus is composed of a cosine computing unit 1 which computes the cosine of a margin-angle instruction value γref , of a multiplier 2 in which a commutation reactor Xi is multiplied by a DC current Id, of a scale multiplier 3 in which the output of the multiplier 2 is multiplied by a factor and of a multiplier 8 in which the margin-angle instruction value γref is multiplied by the output of a scale multiplier 7 so as to output its result to the cosine computing unit 1. Then, by using an expression of cosγ-cosβ=(2<1/2> ).Xi.Id/Ei, a desired margin angle is changed so as to be proportional to the frequency of an AC system. In the expression, represents a commutation reactance for one phase portion, Id represents a DC current, and Ei represents a transformer-valve-winding voltage.  When the margin-angle instruction value γref is corrected in this manner, a constant-margin-angle control apparatus at an AC-DC converter does not generate the failure of a commutation operation even when the frequency (f) of the AC system is changed, and it continues a stable operation.

IPC: H04N5/08
Filed: 1981-01-26
Abstract: PURPOSE:To decrease jitter due to variance in video level and to increase the response speed at signal switching, by additionally providing a clamp circuit having comparatively small time constant with a clamp circuit having large time constant conventionally. CONSTITUTION:A composite video signal enters the 1st clamp circuit 4 and the 2nd clamp circuit 6 provided additionally, which constitute a synchronizing separation circuit as shown in the figure.

Thus, the jitter of the front edge of a synchronizing signal separated at a comparator from this signal is also less. On the other hand, the time constant of the 2nd clamp circuit 6 is comparatively small, clamp pulses are generated in a short time at a slice circuit 7, and clamp circuits 4 and 6 clamp signals after switching in a short time, even if switching is made to a signal with different average level. Thus, the synchronizing separation circuit  with less change in the front edge due to video level and quick response is put into prictice.

Abstract: A technique for printing postage and other value indicia at a user location. A user at a user computer acquires secure postage labels having one or more security features such as serrated edges, a microprint strip, a color fiber, taggants, a watermark, a hologram, or a fluorescent stripe. The labels have associated serial numbers, possibly at the sheet or individual label level. The user establishes communication with a postage vendor system (PVS), which may include one or more servers, and requests one or more indicia. The user also provides one or more serial numbers for the label(s) or label sheet(s) on which the one or more indicia are to be printed. The PVS determines if the one or more serial numbers are valid, and if so, generates information for printing the one or more indicia and then sends the information to the user computer. The information preferably includes a digital signature for each indicium, which may incorporate the serial number. The user computer receives the information and prints the one or more indicia on one or more postage labels.

Title: Power supply
Inventor: SCOTT MARK ALISTAIR
IPC: H05B41/292
Filed: 1988-05-10
Abstract: Arc discharge lamps driven at frequencies in excess of 20kHz may exhibit the phenomenon of 'acoustic resonance' in which longitudinal and lateral acoustic waves are supported in the arc tube. This is a problem because the acoustic wave may give rise to an instability in the discharge arc, causing it to stretch or gyrate and invariably to extinguish. In some cases damage may be caused to the arc tube. A power supply suitable for an arc discharge lamp (1) comprises a drive circuit (10) arranged to supply voltage to the lamp (1) and control means (20) for causing a characteristic of the voltage to vary, with time, in accordance with a pseudo random sequence in order to reduce, or eliminate, acoustic resonance in the lamp (1).
