Patent EP-0366882-A2 (EP)
Inventor: CHIN DAEJE
IPC: H01L27/108
Filed: 1989-08-02
Abstract: This invention relates generally to ultra dense dynamic random access semiconductor memory arrays. It also relates to a method of fabricating such arrays using a plurality of etch and refill steps which includes a differential etching step which is a key step in forming insulating conduits which themselves are adapted to hold a pair of field effect transistor gates (6) of the adjacent transfer devices of the one device memory cells. The differential etch step provides spaced apart device regions and an insulation region of reduced height between the trenches which space apart the memory cells. The resulting structure includes a plurality of rows of vertically arranged field effect transistors wherein the substrate (8, 11, 12) effectively acts as a counterelectrode surrounding the insulated drain regions (5) of each of the one device memory cells. A pair of gates (6) are disposed in insulating conduits (15) which run perpendicular to the rows of memory cells. Each gate (6) in a conduit is disposed in insulated spaced relationship with a memory cell channel region (4) which, in response to signals on the gate turns on a column of channel regions (4) so as to permit the entry of charge into a selected storage region when a bitline (16) associated with a particular cell (2) is energized. The resulting array shows rows of pairs of memory cells (2) wherein each cell of a pair is spaced from the other by a portion (12) of the substrate acting as a counter­electrode and each of the pairs of memory cells is similarly separated from an adjacent pair by regions (11) of conductive material acting as a counterelectrode.

Abstract: The invention generally relates to improvements in the process and storage of formatted voice, graphic and image data. A new editing process allows the same commands to be applied to a plurality of data files of varying resolution and formats. The technique employs an edit tracking file (120) to retain the edit commands applied to a file of a first format. The edit commands are then executed against a file of a second format to perform the identical editing steps to the second file. This process avoids the inaccuracies associated with converting information to a common format while providing the benefits of supporting multiple formats of file information.

Abstract: In a position closest to the mounting position of a microcomputer (5) in a casing (8) of a hybrid integrated circuit device (1) on which is mounted the microcomputer and its peripheral circuit elements, an insertion hole (7) is formed for a non-volatile memory (4) which feeds data to the microcomputer. A socket (15) for connecting the non-volatile memory is provided at the bottom of this insertion hole. Because of this configuration it is possible to connect the microcomputer and the non-volatile memory at an extremely short distance and the mounting efficiency of the integrated circuit device is increased. In addition, the non-volatile memory can detachably be mounted. 
     Furthermore, the external shape of the insertion hole for the non-volatile memory is essentially the same as the external shape of the non-volatile memory so that when the non-volatile memory is inserted, the entire surface of this hybrid integrated circuit device is almost flat, providing excellent handling characteristics.

Abstract: The present invention provides a signal delay circuit for substantially steplessly changing a delay interval. The signal delay circuit is composed essentially of a delay controller, a first delay circuit, and a second delay circuit. The delay controller generates and outputs control data consisting of a real number bearing control information for controlling the delay interval, the real number consists of an integral portion and a fractional portion. The first delay circuit receives an incidental signal, delays the incidental signal for creating a first intermediate signal, and outputs the first intermediate signal, the first intermediate signal being delayed with respect to the incidental signal by an interval which is a product of a predetermined cardinal interval and the integral portion of the real number. The second delay circuit receives the first intermediate signal, produces at least one second intermediate signal by delaying the first intermediate signal by at least one interval which is an integral multiple of the predetermined cardinal interval, interpolates the first intermediate signal and said at least one second intermediate signal for producing a delayed signal, and outputs the delayed signal, the delayed signal being delayed with respect to the first intermediate signal by an interval which is a product of the predetermined cardinal interval and the fractional portion of the real number. As a result, the delayed signal is delayed with respect to the incidental signal by a delay interval which is a product of the predetermined cardinal interval and the real number output by the delay control means.

Abstract: 1. A voice-controlled archival system with a scanning device for entering documents into a mass storage device. 2.1 In the past, the applications have been investigated for which the keyboard can be replaced by a voice input device. For the archival system application, it is found quite clearly that the use of a voice input device is only possible for inputting control commands. For inputting the information characterising the content of the document, the keyboard or corresponding devices generating text data must still be used. 2.2 The voice-controlled archival system according to the invention, also called Arc-Voice system, for the first time makes it possible to utilise a voice recognition system for inputting the information characterising the content of the document. The voice recognition system exhibits, among other things, a speech processor. The speech processor is connected to a control device which contains an access device and carries out a plausibility check by means of the available "prior knowledge" during the command and/or word recognition process.   2.3 The Arc-Voice system is preferably used for archiving bulk documentation. <IMAGE>

The second stage (A₂,  A ₂) includes a cross-coupled transistor quad with the bases of the first quad pair coupled to the collectors of the first stage transistors. The inter-stage coupling circuit includes a series string of diodes connected between the collectors of the first stage transistor pair. The input stage transistor pair is identical to the transistor pairs of the second stage quad, and all of those transistors carry identical DC currents. An output stage amplifier (A4) is driven by a signal from the collectors of the first transistor pair of the second stage quad (A₂,  A ₂). The second transistor pair of the quad is coupled to the output stage (A4) through current mirrors to augment the output signal.

Title: Circuit for regaining the chrominance signal
Inventor: REIME GERD
IPC: H04N9/87
Filed: 1990-11-10
Abstract: A circuit for recovering the chrominance signal from a read signal which is read from a tape with adjoining helical tracks exhibits in familiar manner a circuit arrangement (11) for separating a raw chrominance signal (S1) from the read signal, a 2H delay section (49) and an adding section (50) for adding a respective undelayed raw chrominance signal and a respective 2H-delayed raw chrominance signal, forming an addition signal (S2). In addition, there is a subtracting section (12), a threshold circuit (13) and a second adding section (14). The subtracting section subtracts the undelayed and the delayed raw chrominance signals from one another, forming a difference signal (S3). This signal, after passing through the threshold circuit where a noise-free signal (S4) is obtained, is added by the second adding section to form the addition signal (S2). The signal formed in this addition is a chrominance signal without crosstalk interference and without colour errors at vertical colour transitions. <IMAGE>

Abstract: A simple and economical method of mass analyzing a sample by means of a quadrupole ion trap mass spectrometer in an MS/MS mode comprises the steps of forming ions within a trap structure, changing the RF and/or DC voltages in such a way that the ions with mass-to-charge ratios within a desired range will be and remain trapped within the trap structure, dissociating such ions into fragments by collisions, and increasing the field intensity again so that the generated fragments will become unstable and exit the trap volume sequentially to be detected. A supplementary AC field may be applied additionally to provide various scan modes as well as dissociate the ions.
