Character generator with address memory and data storage unit for controlling dot matrix output unit
Patent number: 4740784Abstract: A character generator which converts character code words into data items, namely column code words (C code), for controlling a dot matrix output unit, is disclosed. The character code word is presented to an address memory circuit which generates a ten-bit-long column address (CAD) that identifies the locations of the column code words within a separate data storage unit. The address memory circuit includes two memory units (PROM 1, PROM 2) which store only the first eight bits of respective column data addresses, while an additional memory unit (PROM 3) stores the remaining two bits of the respective column data addresses. A multiplexer (15) is used to select the correct two bits of each respective column data address from an eight-bit word output by the additional memory unit (PROM 3) at the same time an eight-bit address is being output by one of the first two memory units (PROM 1, PROM 2).Type: GrantFiled: July 14, 1986Date of Patent: April 26, 1988Assignee: Nixdorf Computer AGInventor: Wolfgang Fick -

Patent number: 4738236Abstract: According to the invention, a combustion chamber for internal combustion engines is constructed by forming a combustion chamber recessed in the head portion of a piston, and disposing therein a fuel injection nozzle means that atomizes and supplies the fuel thereinto in such a manner that the plural number of fuel mists formed by the fuel injection nozzle means will strike the inner wall of the combustion chamber at intervals at the outside of the swirl generated in the combustion chamber but adhere to the combustion chamber inner wall flowing in the direction of the swirl. Therefore, the fuel so supplied does not cool the combustion chamber inner wall excessively, and itself is heated by the heat of the inner wall as well as by the heat of the compressed air so to vaporize easily, so that favorable dispersion and distribution of the mixture gas within the combustion chamber is ensured, developing stabilized power output and sustaining favorable combustion while suppressing the exhaust of HC and NOx.Type: GrantFiled: April 7, 1987Date of Patent: April 19, 1988Assignee: Isuzu Motors LimitedInventor: Hideo Kawamura

Patent number: 4736384Abstract: An electrode adding apparatus which adds a new electrode to an electrode held by the electrode holder of an electric furnace by screwing the lower end of the new electrode in the upper end of the electrode held by the electrode holder, when the electrode held by the electrode holder is consumed. In adding the new electrode to the consumed electrode, the new electrode is gripped by a clamping device rotatably held by a casing, then the casing is transported by a crane to bring the new electrode directly above the consumed electrode, and following which the casing is lowered to position the new electrode in alignment with the consumed electrode. Then, the clamping device is driven for rotation to screw the lower end of the new electrode in the upper end of the consumed electrode. In adding the new electrode to the consumed electrode, the rotative reaction force of the casing is received by the electrode holder so that the casing is restrained from rotation.Type: GrantFiled: December 4, 1986Date of Patent: April 5, 1988Assignees: Kyoei Steel Ltd., F.

Patent number: 4734003Abstract: A wood joint connector plate is formed of a thin, rigid metal sheet having numerous narrow, elongated, struck-out openings. The struck-out sheet material is bent perpendicularly at each end of each opening to form a pair of opposing reverse-oriented mirror-image teeth. Each tooth is bent about a lengthwise bend line that is offset relative to the central longitudinal axis of its opening to divide the tooth into a narrow portion and a wide portion along its length. The free end of each tooth is formed as an asymmetrical V-shaped tip, whose apex coincides with the bend line, to provide a short leg terminating the tooth narrow portion and a long leg terminating the tooth wide portion. Each tooth is twisted around its bend line so that its tip short leg extends approximately parallel to the axis of the opening and towards its opposing tooth. The tip long leg extends away from its opposing tooth and its opening at an acute angle relative to the longitudinal axis of the opening.Type: GrantFiled: December 22, 1986Date of Patent: March 29, 1988Inventors: Glenn C.

Patent number: 4733642Abstract: Described herein is a combustion chamber for internal combustion engine, including a protuberance extending radially inward from a peripheral wall surface of a combustion chamber which is formed by hollowing the top of a piston in the axial direction thereof. The protuberance induces rolling streams turning in the same direction as the fuel swirl thereby collecting air and atomized fuel in a region on the upstream side of the protuberance. The rolling stream serves to improve the ignition quality by enriching the concentration of fuel vapors in that locality. The flames generated in the vicinity of the protuberance are propagated to the atomized fuel which is supplied to other regions of the combustion chamber, thereby providing an internal combustion engine with improved ignition and combustion qualities.Type: GrantFiled: December 10, 1986Date of Patent: March 29, 1988Assignee: Isuzu Motors LimitedInventor: Shiro Ishida

Patent number: 4728887Abstract: A system for determining the current carrying capability of one or more overhead power transmission lines monitors one or more spans of each line on real-time basis and identifies the span having the lowest current carrying capacity which in turn establishes the maximum capacity of the entire line. The thermal state of each monitored line span is determined by measuring the conductor temperature, line current, solar radiation, ambient temperature, and in some cases wind speed and wind direction. These parameters are monitored by a sensor-transmitter unit that may be removably clamped on the line conductor which may range in size from one to several inches in diameter, and includes a radio transmitter for transmitting sensed data to a receiving substation.Type: GrantFiled: June 22, 1984Date of Patent: March 1, 1988Inventor: Murray W.
