IPC: G06F13/30
Filed: 1988-01-08
Abstract: A direct memory access (DMA) controlled system which performs DMA data transfer between a main memory (21), a cache memory (7), and disk memories (5,6) while exchanging DMA transfer requests and acknowledgements among disk control units (2,3), a memory-to-memory transfer control unit (13), and a common DMA control unit (12). The data transfer speed between the main memory (21) and cache memory (7) is variable according to the load condition of the DMA control unit (12) for the disk memories (5,6), enabling the transfer capability of the DMA control unit (12) to be kept at a fixed, continually high level.

Abstract: The testing device checks the coplanarity of the leads (14) of a surface mounted component (12) on a plane defined by the three longest leads of the component. The device comprises first and second conductive plates (20, 26) separated by a non-conductive spacer (24) and conductive spring means (24) having arms (28) providing electrical connections between the plates (20, 26). One of the plates (20) carries a plurality of non-conductive pins (16) associated with the arms (28). When the leads (14) of a component (12) are applied to the pins (16) the arms (28) associated with pins (16) contacted by leads (14) having coplanarity within the thickness of the spacer-means (24) break their connections between the plates (20, 26) while any connections remaining are indicated by an earthed indicator means (30).
Patent EP-0295908-A2 (EP)
Title: Flue gas desulfurization
Inventor: ABRAMS JACK Z
IPC: B01D53/77
Filed: 1988-06-16
Abstract: Efficient removal of sulfur dioxide from a flue gas stream is achieved in a scrubber using a recirculating aqueous stream containing magnesium hydroxide and magnesium sulfite which together act as a SO₂ absorbent. Magnesium sulfite is derived from magnesium hydroxide, which is the product of a reaction between soluble magnesium from the seawater and calcium hydroxide added to the scrubbing system. Magnesium sulfite and bisulfite are oxidized to magnesium sulfate by the introduction of air. Magnesium sulfate is converted back to magnesium hydroxide by reaction with additional calcium hydroxide, with gypsum as a by-product. Gypsum is soluble in large amounts of seawater and may be returned to the ocean without adverse environmental impact.

Abstract: Image data is composed from primitives (polygons) to attain data for displays with the removal of hidden surfaces and smooth-appearing edges. Defined polygons are tested for priority in a determined field of vision by scan conversion to specify individual picture elements (pixels). Polygon contention for pixels is resolved by determining the edge of intersection between the planes of such polygons and testing the signs of certain values in accordance with predetermined criteria. Subpixel priority is treated for similar resolution to provide improved antialiased images.

Abstract: An optical beam splitting method and optical beam splitting/modulating method for recording halftone plate images on a recording material through controlling a light exposing device by image signals obtained by photoelectric manipulation of an original image. Two light beam splitters (8 and 9) are used so that a single light beam can be split into a plurality of split light beams which are lined up in two rows and shifted by one-half pitch with respect to each other and then modulated in multi-­channel ultrasonic modulators (10 and 11), one row of the light beams being modulated with a delay without causing crosstalk. The number of split beams to be modulated is approximately doubled compared to a conventional system, and the size of the dots on the recording material can be decreased so that the image resolution is remarkably improved.

Abstract: The masking member (100) which is used to protect a part of an article from a surface treatment, consists of a thermoplastic resin in which an inorganic filler is mixed. Said masking member has a good mechanical strength and heat resistance so that said masking member can completely protect said part and can be reused. Further the thermoplastic resin as the material of the masking member can be saved and heat of combustion from the combustion treatment of the waste masking member can be also reduced since said inorganic filler is mixed in said thermoplastic resin as a non-­combustible material.

Abstract: The pixel clock of a system for receiving, sampling, and digitally storing the information contained in an analog sampled-data video signal is automatically synchronized and stabilized so that the received data is sampled by said system at or near the center of each successive received pixel period. A preset counter is employed to determine whether the receiving system clock is running at a predetermined number of pixel periods per horizontal sweep; any variation from the predetermined number is sensed and converted to a DC voltage level which is used to adjust the receiving system clock automatically to the correct number of periods per sweep. Synchronization of the receiving system clock is accomplished by triggering it with the sync pulse portions of the received video signal.
