IPC: H04N5/44
Filed: 1969-12-30
Abstract: 1289556 Electro-photographic apparatus ADDRESSOGRAPH-MULTIGRAPH CORP 30 Dec 1969 [21 Jan 1969] 63365/69 Heading G2H An electro-photographic apparatus has a photo-conductive member in the form of an endless belt 420 provided with marks 530, 539 which are sensed by means such as photo-cells 524B cooperating with a light source 524A to control the operation of the apparatus. A glass plate 404 receives an original to be copied for illumination by a flash source (not shown). An optical assembly for projecting an image of the original on to a planar position 424 of the belt 420 comprises mirrors 412, 414 and a lens 416 slidably mounted on rods 419 actuated by a linkage 421 for varying magnification. A corona discharge 432 charges the belt 420 uniformly, in advance of imagewise exposure. A paper feed assembly feeds copy sheets to a pressure transfer station 440 to receive a developed image from the belt 420. Copy sheets S are stacked on a vertically movable pile table 442 to bring the top sheet into contact with a feed wheel 446 controlled between a feeding and raised position by a solenoid 478 actuated for each sheet by a detector 588. Sensing devices 520B, 522B, 524B and 526B, such as photo-cells, sense the marks 538 and 539 to control the operation of the apparatus through a control circuit, Fig. 16 (not shown), which controls operation of corona discharge 432, feeding, the energization of the flash source, the drive to the developing apparatus and transfer of the developed image to a copy sheet. The control circuit includes a selector for the number of copies of each original required. In another embodiment, Figs. 2 and 11 (not shown), an assembly (58) carrying an endless photo-conductive belt is pivotally raised into an inoperative position. An exposure station (164) Fig.10 (not shown) includes a transparent cylinder (178) housing a tubular lamp (not shown) such that as an original passes between the photoconductive belt and the cylinder light is emitted through an elongated slot (188) to form a latent image on the belt. The sequence of operation is controlled by cam operated switches, Fig. 11 (not shown) in this embodiment. The photo-cells may be replaced magnetic detectors, or optical detectors sensitive to different types of radiation in conjunction with markers such as transparent materials or electromagnetic detectors sensitive to a charge carrying marker.

Title: Method of recording spin resonance spectra
IPC: G01R33/46
Filed: 1972-03-30
Abstract: 1334819 Spin resonance spectrometers SPECTROSPIN A G 30 March 1972 [28 May 1971] 15214/72 Heading G1N In a spin resonance spectrometer of the type in which interferograms are averaged and the resonance frequencies determined by Fourier Analysis, the sample spins are excited by two sets of R.F. pulses differing in phase by 180 degrees, at least approximately equal numbers of pulses from each set being used, and the averaged interferogram is obtained by adding the interferograms excited by the pulses of one set to those excited by the pulses of the other set with the sign reversed. Thus, interference signals caused by switching, cancel out. Pulses from the two sets may alternate, singly, in groups of equal number of pulses, or stochastically. The invention may be applied to spin echo spectroscopy and "deft" and "seft" cycles are explained with reference to Fig. 4 (not shown). In Fig.1, R.F. from R.F. generator 22 is modulated at 13 by a train of pulses (31) of alternate polarity from a pulse generator 23. Spin resonance signals from the sample 12 are amplified in a pre-amplifier 14 gated on by pulses (33) from generator 23 in the intervals between the R.F. pulses (32) applied to excite the spins. The output from amplifier 14 is heterodyned in a mixer 15 with the output of a local oscillator 24, amplified at 16 and phase detected at 17. The detected signals pass through a low pass filter 18 to a mean value converter 19 which receives pulses (34) from pulse generator 23 to determine the sign for each signal. 20 denotes a Fourier transformer.

Title: Multi-range regulated dc power supply
IPC: G05F1/573
Filed: 1972-05-11
Abstract: 1346559 Rectifying POWER DESIGNS Inc 11 May 1972 22217/72 Heading H2F [Also in Division G3] A D.C. power supply includes a number of unregulated sources, each capable of providing a different output range and connected through diodes to common output terminals. Each source is connected through a variable series resistance element, and the appropriate source is automatically switched to the output terminals to provide a regulated supply at a required voltage or current. In the system shown, four power sources are formed by capacitors 54-57, charged to successively higher voltages, but with reducing current supply capability. Each capacitor is connected to output terminals 84, 85 by way of a regulating transistor 87, 95, 97, 101. Transistor 87 is connected in parallel with a similar transistor 86. Each source also has an associated current sensing circuit. For the first source, this circuit comprises resistors 88, 89, 91, range setting switch 92, and transistor 148. The circuits for the other sources each include a current sensing resistor 96, 98, 102 and a transistor 153, 155, 157 respectively. If any one of these four circuits detects an excessive current, transistor 159 is biased on to reduce the current in driver transistor 109. The arrangement also includes circuitry for generating reference voltages, including RF filter circuit 21-23, constant current circuit CC, and a warning limit circuit including neon lamp 38. In operation, if a low voltage output is required, this is supplied from the first source comprising capacitor 54 through series regulating transistors 86, 87, with transistors 95, 97, 101 and 109 functioning as drivers. Voltage stabilization is achieved by comparison of the output voltage sensed by terminals 130, 137 with the Zener diode 34 at point V so as to adjust the transistor drive. If the required output voltage rises, or the supply falls, so that the first source is no longer capable of supplying the necessary output, diode 51 blocks, and the second source supplies current from capacitor 55 through regulating transistor 95, current sensing resistor 96, and the base-emitter paths of transistors 86, 87. Further increases in the desired voltage lead to diodes 52, 53 blocking, until the supply is derived solely from capacitor 57. If the required voltage cannot be provided by any of the sources, or if the system is operating in a current limiting mode, transistor 109 tends to saturation, and the current in a resistor 45 becomes large enough to cause Zener diode 46 to break down. Transistor 42 is cut off, and the supply from winding 35 is sufficient to cause the neon lamp 38 to flash as a warning indicator. Remote programming terminals 133, 134 are provided, together with coarse and fine output voltage adjusting resistors 135, 136. A meter 171 can be connected through a switch 172 to monitor the output voltage or current.

Title: Apparatus and method for providing a programmable delay
IPC: H03K5/13
Filed: 1997-03-28
Abstract: A printed circuit board tester that compensates for the different propagation length of each channel including a single-input delay cell, at least one multiple-input delay cell, and a multiplexor. The delay cells are connected to one another in a chain. Further, the single-input delay cell is the first delay cell in the chain, and each multiple-input delay cell has the ability to select one of its inputs. A timing signal is applied to each delay cell, and to the multiplexor. The inputs of the multiple-input delay cells are connected to the output of the single-input delay cell, and to the outputs of any preceding multiple-input delay cells in the chain. The single-input delay cell delays the timing signal. Each multiple-input delay cell is programmed by the tester to select one of its inputs; it then delays the selected input. Finally, the multiplexor is programmed by the tester to select either the timing signal or one of the outputs of the delay cells. The signal selected by the multiplexor is the timing signal delayed by an amount necessary to compensate for the propagation length of the channel.

Title: Balanced surface acoustic wave filter
Inventor: TAGUCHI YUTAKA
IPC: H03H9/64
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To provide the balanced surface acoustic wave filter which can obtain large attenuation over a wide band. SOLUTION: A symmetrical grating type 1st surface acoustic filter is manufactured by using two resonators 101 of a serial arm and two resonators of a parallel arm each. A symmetrical grating type 2nd surface acoustic wave filter is manufactured by using two resonators 103 of the serial arm and two resonators 104 of the parallel arm each. The 1st surface acoustic wave filter and 2nd surface acoustic wave filter are cascaded. The antiresonance frequency of the resonators 101 of the serial arm and the resonance frequency of the resonators 102 of the parallel arm are nearly equalized to each other and the antiresonance frequency of the resonators 103 of the serial arm and the resonance frequency of the resonators 104 of the parallel arm are nearly equalized to each other.  The equivalent parallel capacity ratio (equivalent parallel capacity of the resonators of the serial arm/equivalent parallel capacity of the resonators of the parallel arm) of the surface acoustic wave filter as a 1st stage is made different from that of a surface acoustic wave filter as a 2nd stage.
