Patent EP-0315336-A2 (EP)
Inventor: KOLECKI NORMAN S
IPC: H02M7/06
Filed: 1988-10-19
Abstract: A power supply line has two to four lead wires (12a-12d) which are selectively connectable with terminals (10a-10d) of a transformerless AC-to-DC converter (A). The lead wire interconnection scheme is selected (FIGURE 1C-1F) in accordance with whether the line signal is single phase or three phase and whether the line voltage is 220 or 440 volts. The AC-to-DC converter (A) produces a 620 volt DC signal across its outputs (26,28). A first inverter (B) converts this DC signal to a pulsed AC signal and applies it across opposite phased primary windings (46a,46b) of a step up transformer (C). Two pairs of alternately phased secondary windings (48a-48d) and rectifier bridges (50,52) provide a high voltage DC bias across a cathode (54) and an anode (56) of an x-ray tube (D). A summing junction (66) compares a voltage sensed across the x-ray tube (D) with a reference voltage and generates a voltage deviation signal. A deviation signal adjustment algorithm (68) adjusts the deviation signal in accordance with a ratio of the selected tube operating current and voltage. A pulse width modulator (82) controls the first inverter (B) to control the duty cycle of the pulsed AC signal in accordance with the adjusted deviation signal. A second summing junction (102) compares sensed tube current with a reference tube current to produce a tube current deviation signal in accordance with the deviation therebetween. A second pulse width modulator (106) and a second inverter (F) apply a pulsed AC signal, whose duty cycle varies in accordance with the deviation between the sensed and reference currents, through the filament (54a,b) of the cathode (54).

Abstract: A digital video tape recorder. A clock is extracted from the horizontal sync signal within the luminance signal, and used in processing the luminance portion of the video signal. A clock is also extracted from a color burst within the chrominance signal and is used for processing the chrominance portion. The chrominance portion of the video signal to be recorded is converted to a low frequency band before recording. During playback, the reverse of this operation is performed, thereby producing a signal with the original color frequency.

Abstract: A memory cell is provided comprising a bistable latch (I1, I2) having first and second nodes (NODE 1, NODE 2) and a nonvolatile transistor (NV1). 
     The control gate of the nonvolatile transistor is connected to the first node and either the source or drain is connected to the second node. Means are provided for maintaining the control gate and the substrate of the transistor at substantially the same potential during volatile operation of the latch, thereby to reduce voltage stress which would lead to charge tunnelling to or from the floating gate. In this way, disturbance of the floating gate charge is avoided during volatile operation. The cell is particularly suited to silicon gate fabrication technology.

Abstract: A cache memory is connected to the microprocessor via a MPU bus and to the main memory via a memory bus. The data transfer between the main memory and the data memory DTM of the cache memory is executed block by block via the buffer memory BM. The directory memory DLM holds, as address tags, the high-order bits of the main memory addresses of the data stored in the data memory DTM. A tag comparator TCP compares an address tag stored in the directory memory DLM with the address tag derived from the MPU-bus and produces a signal CH which indicates a coindicende (cache-hit) or a non-coincidence (mis-hit). In the case of a cache-hit, a data transfer is executed between the microprocessor and the data memory DTM instead of the main memory. 
     The cache memory has a function of monitoring any address change in the main memory due to a dynamic relocation or garbage collection e.g. The address change implies a data-°­transfer start address and a data-transfer end address. 
     In case of an address change in the main memory, the cache memory automatically updates the internal address tag in conformity with the data-transfer start and end address.

Built-in steam control valves (40) are provided to control the amount of steam applied to each section. Suction means (50) may also be provided upstream of the nozzles, with reference to the movement of the calenderable material, to remove excess steam and thus prevent undesirable condensation on adjacent structures.

Abstract: A dispensing gun for viscous materials comprises a stock (12) supporting a push rod (28) which is advanceable along a keep (13) in which is mounted a cartridge of the material. The rod is advanced by means of a catch plate (41) and trigger (43) arrangement which bites on the rod and is retreated by a return spring (42). A release plate (51) prevents the rod retreating with the catch plate. The release plate is frictionally engaged with the rod so that it acts as a lost motion brake once force is removed from the trigger. In this way the rod is allowed a limited retreat to take the dispensing force off the cartridge to prevent leakage when the trigger is not depressed.

Abstract: A bus interface between a data bus and data storage devices provides error protection for multi-byte data packets received from the bus and intended for storage on an associated storage device by checking the data symbols in a packet for errors using check sum and parity symbols included in the packet. The bus interface then (i) encodes a predetermined number of data symbols to generate error detection symbols, (ii) again checks the data symbols for errors using the parity bits, and (iii) stores the data and associated error detection symbols in one of a series of linked buffers. Each buffer holds enough the data and associated error detection symbols to fill one storage unit, or sector, on an associated storage medium. A storage interface later retrieves the buffered data and error detection symbols, combines them with the address of a designated storage sector, and encodes the symbols to generate error correction symbols. It then stores the encoded data, and error detection and correction symbols in the designated sector. When the storage interface later retrieves the symbols from the sector, it corrects errors in the data using the retrieved error correction symbols. It next removes the sector address from the error detection symbols and returns the data and error detection symbols to the bus interface. The bus interface (i) generates parity bits, (ii) checks for errors using the error detection symbols, (iii) generates check sum symbols and (iv) transmits the data, check sum and parity symbols over the bus. If the bus interface at any time detects an error, it stops the data transfer operation.
