Abstract: A refuse compression apparatus (RA) for reducing the volume of a thermal elastic refuse includes a telescopic refuse container (1) which is covered by a bag (4) and is housed in a cylindrical housing (2) as suspended on the top of the cylindrical housing (2). A top cover box (3) is coupled with the telescopic refuse container (1) and the cylindrical housing (2) so that the bag (4) divides the inner space of the cylindrical housing (2) into a free space (13f) inside the bag (4) and an airtight space (13t) outside the bag (4). An air pump (8) provided to connect the airtight space (13t) and the outside of the cylindrical housing (2) operates to pressurize the airtight space (13t), causing that the bag (4) presses the telescopic refuse container (61) to slide up. Thus, the refuse placed in the telescopic refuse container (1) is pressed against the lower surface (3a) of the top cover box (3) and is compressed.

Abstract: A method and apparatus for data collision detection and resolution in a multi-processor communication system. The system includes a plurality of processors (1, 2, 3, 4, 5, 6, 7, 8) coupled via a common bus (9). When it is required that one processor (1, 2, 3, 4, 5, 6, 7 or 8) communicate with another processor (1, 2, 3, 4, 5, 6, 7 or 8), the first processor (1, 2, 3, 4, 5, 6, 7 or 8) determines whether a data collision flag is set. The processor (1, 2, 3, 4, 5, 6, 7 or 8) then checks a number of indicators to determine whether the identity of the transmitting processor (1, 2, 3, 4, 5, 6, 7 or 8) is what it is expected to be. If a data collision is found, the processor (1, 2, 3, 4, 5, 6, 7 or 8) waits a selective time before transmitting a message (30). The processor (1, 2, 3, 4, 5, 6, 7 or 8) then repeats the data collision checking and transmitting the message (30) to the other processor (1, 2, 3, 4, 5, 6, 7 or 8) when no data collision is found. The time to wait is dependent upon the identity of the processor (1, 2, 3, 4, 5, 6, 7 or 8) and is table driven.

Abstract: The subject-matter of the invention is a plug connector for flat ribbon cable (3), having a housing upper part (1), consisting of insulating material, in which a number of parallel guide channels (4) for contact elements having insulation-piercing terminals (5), and a transverse groove (2), which passes through the guide channels, for the flat ribbon cable (3) are arranged, and having a housing lower part (10) which consists of insulating material and in which a number of parallel guide channels (11) for contact elements are likewise arranged. In order to create a plug connector which is easy to instal and in which as many contacts as possible can be accommodated and can reliably make contact with one another in a very confined space, it is proposed that the insulation-piercing terminals (5) of the contact elements in the housing upper part (1) be integrally connected to flat blades (6) located in the same plane, that the contact elements in the housing lower part (10) be constructed as fork-spring contacts (12) and be arranged at right angles to the flat blades (6), and that the flat blades (6) and fork-spring contacts (12) engage over one another and make contact with one another in a contact channel (14) which is formed by the housing upper and lower parts (1, 10). <IMAGE>

Abstract: Video images are encoded by transform coding, resulting in data blocks each including a DC-coefficient and a plurality of AC-coefficients. The coefficients of a number of said transform blocks are variable-length encoded and transmitted. In order to avoid a complete loss of datablocks in case of a transmission error, the most significant codewords of a group of blocks are transmitted first so as to achieve that at least the DC-level of the blocks is likely to be retained. 
     The coefficients may also be recorded on a videorecorder. The DC-coefficients and if desired predetermined AC-coefficients of selected ones of the transform blocks are packed together to form a DC-packet to be recorded on a selected part of the track. The DC-packet is chosen such that it can be read out as a unit at various search speeds, and can be read partially at higher search speeds.

Abstract: A synchronizing clock generating circuit for generating synchronizing clock signals (WCK) timed to synchronizing signals (SH) contained in input video signals is disclosed. A trapezoidal wave from a trapezoidal wave generator (19) and a reference pulse (RP) from a reference pulse generator (12) are compared as to phase in a phase comparator (21), while the trapezoidal wave and a pseudo reference pulse (rp) from a pseudo reference pulse generator (23) are compared as to phase in a phase comparator (22), and a difference between outputs of these phase comparisons is used in a dc detection circuit (24) for controlling the gradient of the trapezoidal wave. An output of a VCO (15), controlled by the results of phase comparison between the trapezoidal wave and the reference pulse (RP) is used as a synchronizing clock signal. In this manner, the synchronizing clock signal is stabilized in frequency, while frequency deviations produced by temporal changes in component parts or temperature variation may be corrected to prevent deterioration, such as bends or distortions, from being produced in a reproduced picture, thereby improving the picture quality.

Abstract: A control method and system when a flash memory is used as a semiconductor disk or a main memory in an information processing system. A semiconductor file system comprises a first nonvolatile memory electrically erasable, a second nonvolatile memory not electrically erasable, a volatile memory, a controller which controls the memories, and a control section which controls the controller wherein a physical address corresponding to a logical address specified from an external system is accessed. The first nonvolatile memory stores data for the external system to perform operations, first management information indicating the correspondence between physical addresses at which the data is stored and logical addresses, and second management information indicating a state of the first nonvolatile memory. The second nonvolatile memory previously stores interface information required for inputting and outputting the data from and to the external system and read-only data of the data. The controller comprises control means for determining a physical sector address forming predetermined high-order bits of the physical address when data is output from the first nonvolatile memory or when data is input to the volatile memory, means for storing the determined physical sector address, and means for consecutively generating addresses in a sector determined by the physical sector address. The control section is responsive to the interface information, the first management information, and the second management information for controlling input/output of data from/to the external system and for temporarily storing write data into the first nonvolatile memory from the external system in the volatile memory and then transferring the write data from the volatile memory to the first nonvolatile memory. The consecutive address generation means and the sector address storage means output the physical sector address and the consecutively generated addresses to the first nonvolatile memory and the volatile memory when data at the physical sector address is output from the first nonvolatile memory or when data at the physical sector address is input to the volatile memory.
