Abstract: An opening and closing mechanism 18 for photographic film cartridges 12 of the type having a film-receiving tray 20 with outwardly extending front and side lips 30 and a flexible cover 22 for the tray resealably engaged with the lips. The opening and closing mechanism 18 includes a cartridge-receiving base 16 with front and side lips 68 for supporting the front and side lips 30 of the tray 20. A carriage 90 is mounted for movement with respect to the base 16. An elongated roller 80 including cartridge cover-engaging fingers 88 is rotatably and movably mounted to the carriage 90. Springs 110 bias the roller toward engagement with the lips 68 of the base 16. A carriage drive assembly 92 includes a roller drive linkage 124, a track drive linkage 122, a motor 126 and a shuttle linkage 128. A rack 120 is mounted adjacent to the base 16 for engagement by the track drive linkage 122.

Abstract: A multichannel optical measuring system comprises an arrangement whereby light from a single light source (1) is directed through a condenser lens (8), and then through a multiple interference filter arrangement (4) in which filters can be selected to select light of prescribed wavelengths, and multiple bundles of quartz optical fibers (51) are used to project the light of the selected wavelengths at glass measurement cuvettes containing biological cell samples (9) that are the measurement targets. This multiple optical fiber arrangement makes it possible to irradiate a multiplicity of glass measurement cuvettes using just one light source and one related optical system, thereby achieving a measurement system that is smaller and more resource-efficient.

Abstract: A read only type optical disc, and disc drive apparatus for reading/additionally writing data into the disc. The disc has a recording material (7) formed in all of the tracks (6) by which data can be additionally recorded on the disc (1). This optical disc has a plurality of sectors (S₀ - S n ) forming a data read-only area (4) and a write/read area (3). Each area has track sectors (S₀ - S n ) each having a sector identifier portion (ID) in which address information is recorded and a data field portion (DF) to record data. Data-field identification flags (F₁, F₂) indicative of the read-only area (4) and the write/read area (3) are recorded in the respective identifier portions. On reading or writing this optical disc, the data field identification flag is detected to identify (16, 26, 28) the kind of related area i.e., read-only area or write/read area. Thus, it is possible to avoid (18 - 22; 28, 34) erroneous recording of data into the read-only area. Upon reading operation, waveform equalization and binary-clipping level of reproduction signals can be well controlled (26, 37, 39). The gain of the servo loop can be switched (53, 54). The track searching operation can be stably performed (58 - 63). The data reading and data writing into the data write/read area can be improved.

Abstract: A method for regulating the flow in a distant-heating transfer station is proposed, in which a pressure difference is produced by way of a defined cross-sectional narrowing provided in a bypass line to a main line, as a function of the regulated volume flow of the bypass line, and as a result of this pressure difference the flow through a main valve in the main line is regulated. An apparatus with a regulating member in a main line provides for a cross-sectional reducer and a regulator to be arranged in a bypass line and for the regulating member to be subjected to the pressure difference via the cross-sectional reducer.

Abstract: A signal light (101) and a clock light (102) which is generated by a clock light generator (11) are propagated through a non-linear optical medium (4) of, for instance, a silica-based single mode optical fiber, from which the signal and clock lights and a four-wave mixing light (103) are obtained. One light, for instance, the four-wave mixing light is extracted from the output lights of the non-linear optical medium, and a control signal which is dependent on a time-mean value in power of the extracted light is applied to a voltage controlled oscillator (VCO) (10) for driving the clock light generator (11). Thus, a clock light which is locked in phase to the signal light is obtained. In case where the signal light comprises N time-division sequential lights (N = 1, 2, 3, -----), and a clock frequency of the clock light is 1/N of a clock frequency of the signal light, each one of the N time-division sequential lights is shifted in phase or frequency by the non-linear optical medium, so that the phase or frequency shifted sequential light is switched to be demultiplexed by a switch device such as an optical coupler and a polarization beam splitter.

Abstract: The method decodes a stream of video data representing images. The video data stream (V1) is encoded with a transformation coding. The data in the data stream are decoded by means of a transformation decoding. The decoded video image data are temporarily stored in a memory device (15), with fewer image points or pixels relative to the images contained in the input end video data. Before the temporary storing, the video data stream is filtered with a low pass filter, in relation to the image information in the data stream. In the filtering, only those input data values to which low frequency components of the input image information are allocated, are fed to the decoding stage. The circuit arrangement for executing the method has an input buffer memory (11) to which the video data stream is fed. It also has a device (13) connected to the buffer (11) for calculating an inverse discrete cosine transformation . The images generated from the transformation are stored temporarily, in a memory device (15).
