Patent EP-0391584-A2 (EP)
Inventor: SIMPSON DAVID L
IPC: G06F5/12
Filed: 1990-03-23
Abstract: A FIFO memory system for buffering data between two data buses includes a RAM memory (12), write and read pointer registers (14, 16), an offset generator (16), a programmable offset register (20), and a comparator (22). The write pointer register (14) stores the address of the next data element to be written into the RAM memory (12), and the read pointer register stores (16) the address of the next data element to be read from the RAM memory (12). The offset generator (18) compares the contents of the registers (14, 16), and generates at an output thereof an offset signal representing the amount of memory space occupied. The programmable offset register (20) provides a programmed offset signal. The comparator (22) compares the offset signal and the programmed offset signal, and provides a ready signal when the offset signal is greater than or equal to the programmed offset signal. In one embodiment, the addresses stored in the write and read pointer registers (14, 16) are encoded in a minimum change code such as Gray code.

Abstract: A reduced calorie, high base content chewing gum composition is disclosed which possesses a greater, more intense initial flavour impact of increased duration. Its preparation utilizes highly fractionated or rectified flavour oils from which are removed some terpene components, e.g. the monoterpene and sesquiterpene components, resulting in an enhanced and sustained flavour release from the gum base. The "deterpenated" oils have a lesser affinity for the gum base allowing for the use of higher gum base levels for the reduction of calories without the flavour oils being trapped therein. The sustained flavour release is also improved by the complete or partial renewal of several bitter tasting components previously associated with the oils.

Abstract: Esters of monosaccharides and their lower alkyl glycosides are effective both as surfactants and as bleach activators (peracid precursors). The compounds are non-toxic and biodegradable. They act as nonionic surfactants and are effective in soil removal from textiles, e.g. of fatty soiling. In the presence of a hydrogen peroxide source, the sugar derivatives are perhydrolyzed during the washing process to form long-chain peracid. This enhances the bleaching effect, especially on hydrophobic stains.

Abstract: A three-phase motor (10) is operated by a controller having sets of thyristors (16,17,18) which when triggered switch electricity from each phase (A,B,C) of a supply to the motor. The motor (10) is started by triggering the thyristors (16,17,18) to be conductice during successively greater portions of each cycle of the AC power. In order to reduce the cooling requirements for the controller, a contactor (15) is connected in parallel with the thyristors (16,17,18) to provide apply power to the motor (10) once it reaches full speed. When the controller receives a signal to stop the motor (10), the contactor (15) is deactivated and the controller goes through a sequence to synchronize the thyristor triggering process to the phase of the AC power supply. The synchronizing process provides a smooth transition from contractor control back to the thyristors control of the electricity application to the motor (10). Once the thyristor control resumes, the controller executes a triggering routine which decreases the voltage applied to the motor.

Abstract: The stress applied to a gate insulation film can be reduced by raising the potentials of the source and drain terminals of input gate transistors (P1, N1) whose gate are applied with a high potential to a Vcc level or the like, when a programming high potential (V PP ) or a high potential for tri-state control is applied to an external input terminal (31) of an input-stage circuit of an EPROM. Therefore, occurrence of problems of the reliability such as TDDB can be prevented and thus a highly reliable nonvolatile semiconductor memory device can be provided. Further, the elements can be miniaturized to increase the capacity of the nonvolatile semiconductor memory device, without scaling the conventional programming high potential and the high potential for tri-state control.

Abstract: An apparatus for decoding a coded image into a pixel image and printing the pixel image at an essentially constant speed without using decoding means which decodes the coded image faster than a printing speed and pixel memory means for storing at least one page of pixel information. Decoding amount calculation means (10) for calculating the decoding amount of the code to be decoded is provided, and compare means (12) monitors whether the decoding amount exceeds the printing amount of the pixels to be printed and the code is converted to other code depending on the comparison result. The decoding means (60) needs only receive the converted code from the code memory means (30) and decode it to the pixel information. Thus, the constant speed printing apparatus is attained without high speed decoding means and one-page memory.

Abstract: In a method of forming an image in a form of pixels, the density distribution around the target pixel is obtained by processing image signals of pixels neighboring a target pixel. The target pixel is divided into plural sub-pixels in a form of matrix (n raws x m columns). The sub density distribution of the sub-pixels in the target pixel is assumed from the density distribution of the neighboring pixels. The density of each of sub-pixels is determined by multiplying the density of the target pixel, a constant P and a density ratio of the corresponding sub-pixels in the sub density distribution.

Abstract: An optoelectronic integrated circuit includes a light receiving element for converting an optical signal to an electric signal and an electronic circuit for processing the electric signal. The light receiving element is disposed on a first main surface of the substrate and includes p side electrodes and n side electrodes alternately arranged in parallel to each other. The electronic circuit is disposed on a second main surface of the substrate. The light receiving element is electrically connected to the electronic circuit by a via hole penetrating through the substrate. In this structure, light incident on the first main surface is almost absorbed by the substrate and hardly reaches the electronic circuit on the second main surface. Therefore, variations in operation of the electronic circuit, such as an increase in drain current, are reduced. In addition, since a degree of freedom in arranging these elements on the both surfaces of the substrate is increased, a high-density integration is achieved, resulting in a small-sized IC chip.
