Abstract: The apparatus and method is used for recording optical information on an optical disk and reproducing the optical information therefrom by the use of an optical beam. The system is especially adapted to eliminate crosstalk from nearby tracks even when the position of the beam spot fluctuates with respect to a desired track and even when the size of a beam spot incident to the desired track is varied. The apparatus particularly comprises a frequency characteristic converter which receives output signals from a photodetector array (11). The photodetector array (11), for example, comprises 3 photodetectors (100, 101, 102) receiving input beams (130, 131 and 132). The photodetector (100) is associated with a desired track for reproducing a signal, whereas photodetectors (101, 102) are associated with neighbouring tracks for reproducing a replica of crosstalk. The frequency characteristic convertor (12) further comprises transversal filter means (110, 111, 112), each capable of controlling a frequency characteristic, an adder (120), a reference signal generator (121), an error detector (122), a filter control circuit (123) for controlling the filters (110, 111, 112), a timing control circuit (124), a decision circuit (125), a switch (126) and an output terminal (133). The output of the photodetector (100) adapted to reproduce a signal is fed to the timing control circuit (124), which detects the beginning of a preamble signal written in the track beforehand and delivers a control signal to the reference signal generator (121) and switch (126). When the timing control circuit (124) detects the end of the preamble signal, it delivers a control signal to the reference signal generator (121) and switch (126). The characteristic control for the transversal filters (110, 111, 112) is sequentially performed on the basis of the preamble signal and the corresponding reference signal and on the basis of an input signal and an output signal of the decision circuit (125).

Abstract: To control the correct sequence of decisions in time and provide parameters, in order to avoid lost cycles the necessary control information items are respectively taken with sufficient lead time before the first elementary operation of each machine instruction from a control memory (PECM-N, PECM-C) selected in parallel with the actual microinstruction memory (ECM-A/B) and made available for the sequence control. This analogously applies to the provision of required memory addresses by the address processor (ADW), so that memory accesses for reading operands can be initiated in time without lost cycles occurring with a reduced cycle time for the elementary operations. The same applies to the treatment of operand conflicts. In the case of short instructions with conditional end, lost cycles are additionally saved by utilising the early control information for the earlier recognition of the actual machine instruction end by means of advance tests. <IMAGE>

Abstract: An apparatus for reading an image by using a CCD line sensor (18), including a half mirror (19) or the like dis­posed on an optical path extending from an input opti­cal system to the CCD line sensor, and a linear light source (22) disposed on an optical path branched out by the half mirror. The linear light source is located at a position equivalent to the CCD line sensor with re­spect to a document table (11), and is equal in length to an effective pixel region of the CCD line sensor. Light emitted from the light source is projected back to the document table. An effective image reading area is displayed on the document table by relatively moving the document table and linear projected image in a sub-scanning direction. 
     The linear light source is rotatable in accord­ance with a setting angle of an original. Consequent­ly, an inclined image is projected back to the docu­ment table to serve as a guideline for setting the original. 
     Where a spot light source is substituted for the linear light source, a spot image projected back to the document table is moved along a trimming area of an original. The trimming area is automatically determined by detecting distances of movement of the   spot image.

Abstract: The carriage assembly (22) of this invention includes an oval coil (34) whose shape is maintained by a rectangular bobbin (361 which is passed through the open sides of the rectangular carriage frame (24,26,28,30) and fastened inside the carriage frame so that the ends of the coil protrude from the carriage Frame and define symmetrical semi-cylindrical openings on either side of the carriage for cooperation with the magnetic pole pieces (50,52) of the voice coil motor. The transducers are mounted to arms (84) which fit into precision machined sIots (731 in a head mounting block (70) mounted on the front of the rectangular carriage. The connector cable to the transducers is a printed circuit cable (PCC) that passes directly through the hottom portion of the carriage and lies flat along the path of travel of the carriage between the voice coil motor segments which define the movement of the carriage. A support bracket (60) mounted to the rear of the path of travel of the carriage supports a portion (661 of the PCC and causes it to loop back upon itself as the carriage (22) moves toward the rear of the path of travel. The rear of the carriage is open (67), so that the upper portion of the folded PCC cable loop reaches into the carriage as the carriage reaches the rear of its path of travel, minimizing the space the carriage/PCC assembly will occupy.

Abstract: A single chip integrated data link control (IDLC) device (4) provides full duplex data throughput and versatile protocol adaptation between variably configured time channels on a high speed TDM digital link (3) (e.g. T-1 or T-3 line) and a host data processing system (6). The device handles multiple channels of mixed voice and data traffic concurrently, and thereby is suited for use in primary rate ISDN (Integrated Services Digital Network) applications. Synchronous and asynchronous sections in the device respectively interface with the network and host system. Special purpose autonomous logic elements in the synchronous section form plural stage receive and transmit processing pipelines between the network and host interfaces. Such pipelines perform OSI Layer 2 processing tasks on data in HDLC channels. Each autonomous element comprises one or more state machine circuits having functional autonomy and reduced time dependence relative to other elements. A "resource manager" element (RSM) and time swap (TS) RAM memory operate to dynamically swap states of pipeline elements in synchronism with channel time slots at the network interface, whereby the pipeline stages operate as data buffering stages which perform multiple tasks during any slot. The device contains integrated memory queues in which communication data and channel event status information are stacked for asynchronous transfer. Capacities and modes of operation of these queues are selected to minimize effects on chip size, throughput and cost, while minimizing critical time dependencies between the device and host system. Device elements provide first and second non-interfering information transfer paths between the device and host system; one for exchanges of control/status information between the device and host, and the other for direct memory access transfers of communication data between the device and an external memory associated with the host.
