Abstract: A frame thinning out system has been used as a display driving method for making a gradational display with several brightness levels on the screen of a liquid crystal display device (3) and the like. This is a display driving method making a gradational display by setting a plurality of frame time periods, during which each of pixels on the screen of the display device (3) is controlled for displaying an image, as one integration time period, and turning on pixels only for a number of specified frame time periods corresponding to a brightness level to be displayed out of all frame periods within the integration time period. In this driving method all pixels of the display device (3) are grouped into multiple groups each of which is composed of a plurality of pixels (A, B, C, D, E, F, G, and H) contiguous to each other, the number of pixels to be turned on in each frame time period within one integration time period is selected corresponding to the specified gradation data within the same group, so that the number of pixels to be turned on for one frame time period may be equal between subgroups in the scanning lines within the same group, and the frame time period during which the number of pixels turned on is kept constant is set to a period so short that a human being does not feel flicker. In this way, viewing a plurality of pixels all over one group as a unit image area,   a gradational display without noticeable flicker can be obtained. And since no delicate shades of brightness occur among pixels to the same gradation level, quality of the display is improved.

Abstract: A decoder circuit has a load unit (D1) connected between a high potential power supply line (4) and a decoded output terminal (X), and a plurality of decoder transistors (Q1-Q4) connected in series between the decoded output terminal (X) and a low potential power supply line (5). Gates of the decoder transistors (Q1-Q4) are supplied with input signals (a0-a3). A current supply unit (2) is connected to at least one of a plurality of connection points (P1-P3) of the decoder transistors (Q1-Q4), so that capacitors parasitically formed at the connection points (P1-P3) of the decoder transistors (Q1-Q4) are not only charged by a current from the load unit (D1), but also charged by a current from the current supply unit (2). Therefore an erroneous operation of the decoder circuit caused by the parasitic capacitors can be avoided without increasing its access time and power consumption.

Abstract: A self-synchronizing servo control system and its associated servo data code for use in a high-density disk memory is disclosed. The servo data is formatted into a sync/index zone and a data zone. Sync and index di-bits are written only in the sync/index zone, while only servo data position di-bits are written in the data zone. Elimination of the sync and code di-bits used in prior art methods removes all requirements for radial phase coherence during the writing process, and increases the servo sample frequency. The new servo data code also reduces the intersymbol interference seen by adjacent pulses. The associated configuration of the servo control system is also disclosed.

Abstract: A ring laser (30) is provided with only two reflecting surfaces (34, 36) to define the cavity. A gain medium (32) is located between the reflecting surfaces (34, 36). At least one optical interface (38, 40) is located within the cavity and is oriented such that the beam will be deflected by refraction to create a ring path. The angle of incidence of the beam with the interface (38, 40) should be less than Brewster's angle and the surface should have an antireflective coating. The interface can be located on the lasant material, on a non-linear optical material or on a passive optical element. To achieve unidirectional and single frequency operation, permanent magnets (70) and a quartz rotator plate (74) are provided. When the ring is used for intracavity second harmonic generation, the resultant output is amplitude stable because of the avoidance of mode beating. The second harmonic radiation is generated unidirectionally increasing useable output, by passing the laser beam through a non-linear material (42) within the cavity.

Abstract: A communications system (100) that is arranged to transport so-called connection oriented messages via respective virtual circuit connections is enhanced so that it also transports so-called connectionless messages via a predefined virtual circuit connection that is common among those data modules (110) which participate in the connectionless message service. In particular, each module which participates in the connectionless message service is assigned, in addition to a primary address that is used in conjunction with associated channel numbers to transport respective connection oriented messages, a common address and a channel number that is used solely for transporting connectionless messages. In this way, the communications system processes connectionless messages as though they were connection oriented messages.

Abstract: An ATM cell exchanging apparatus includes an ATM cell switch for a first system #1 and an ATM cell switch for a second system. These cell switches distribute input cells to appropriate output lines. The system also includes selectors for switching the ATM cell switches in accordance with a selection signal that is output from an external system. The ATM switches output an idle cell when there is no cell to be output. When the selector judges that it is necessary to switch the systems as indicated by the change-over signal, the selector switches the system after it confirms that an idle cell is output from both ATM cell switches. The idle cell that is output indicates that there is no cell stored in either system; thus, it is easy to switch the systems without causing the duplication or omission of a cell.

Abstract: A stabilized spray displacement tin plating process of copper printed circuit innerlayers is disclosed for the manufacture of multilayer printed circuit boards. During prolonged use of spray tin plating, the plating solution becomes saturated with cupurous thiourea complex which precipitates interfering with spray nozzles and other mechanical components. The tin plating solution is stabilized by removing portions from the reservoir before saturation is reached, selectively precipitating the thiourea complex, and returning the remaining solution back to the reservoir. The precipitated cupurous thiourea complex is redissolved in acid and either disposed of by conventional waste treatment or the acid solution can be electrowinned to reclaim copper and oxidize thiourea to form a more acceptable acid solution for waste treatment. Preferably,the thiourea is isolated from the anode during electrowinning, so that the acid thiourea solution formed may be used to partially replenish the tin plating solution in the reservoir. By such periodic removal of the complex, the plating bath is stabilized and its useful life is extended dramatically.

Abstract: A document processing system controls the printing of documents represented in page description language form. Documents are represented by a page description language which is structured so that definition and declaratory commands are positioned only at the beginning of each distinct document segment. Each document has prologue sections, which contain definition and declaratory commands, and content portions which contain the specific tokens or commands for defining specific images. The definition and declaratory commands in the prologue sections of the document are arranged in a hierarchical tree so that each definition and declaratory command has a scope corresponding to the portion of the hierarchical tree subtended by that command. A structure processor handles resource declaration and definitions, dictionary generation, context declarations and references to data external to the document. A content processor processes the tokens using the definitions and declarations set up by the structure processor, and an imaging driver module translates the document into commands suitable for any of several types of printers, as well as for communication by telephone line to a remote device. On feature of the document processing system is the ability to query a remote device to determine whether it has the resources required for processing a document transmitted in a high level encoded form. It then either transmits the document in rasterized bit map form if the required resources are not available, or transmits the document in a higher level encoded form if the required resources are available.
