Title: Clock pulse regenerating circuit
Inventor: KAGE GOUZOU
IPC: H04L7/027
Filed: 1978-02-01
Abstract: PURPOSE:To simplify the constitution of circuit by producing synchronous pulse from the changing point of filter output with high Q, controlling the clock pulse generating counter and regenerating the clock pulse from the received burst signal. CONSTITUTION:When the preamble signal from S is received, output x27 of filter 27 is gradually increased in the amplitude and when the instantaneous voltage reaches a value higher than comparative value vc, output x28 of comparative circuit 28 rises. Output x28 passes through gate 32 and clears counter 31 and when counter 31 is cleared, output x31 is reduced to a low level and gate 32 is closed. Output x27 of filter 27 with high Q is compared with comparator 33 and converted to the logical level. With the use of circuits 35 and 36 and elements R1 and C1, output x35 at the rise of x33 is obtained. At gate 36, x35 is subjected to opening-closing of gate by x31. Therefore, the phase of regenerated clock pulse CLK is synchronized with x35.

Abstract: PROBLEM TO BE SOLVED: To provide a diaphragm plate capable of effectively restraining the occurrence of a flare and a ghost without spoiling lightproof property and strength. SOLUTION: This diaphragm plate 2 is constituted of two resin sheets having different thickness. It is constituted by sticking two sheets so that the respective centers of three kinds of diaphragm apertures 3, 4 and 5 being large, middle and small ones of the 1st sheet 2a which is thinner coincide with those of three kinds of transmission ports 6, 7 and 8 being large, middle and small ones of the 2nd sheet 2b which is thicker. Since the strength necessary for the plate 2 is secured by the 2nd sheet 2b, the 1st sheet 2a is thinned and the areas of the inner peripheral surfaces 3a, 4a and 5a of the apertures 3, 4 and 5 are reduced to be able to restrain the occurrence of a flare and a ghost. By using the resin including a lightproof substance, post-processing for securing the lightproof property and reducing the reflectance is eliminated.

Filed: 1993-01-27
Abstract: PURPOSE:To secure a control order without discarding the control order even in a state where in the control order exceeds the throughput of an order controller by skipping processings in order from a low-priority control processing. CONSTITUTION:While the processings are skipped from a low-order controller among a series of control processings as to the currently read control order as temporary storage capacity on an order queue buffer 4 for control orders increases as a result of its monitoring, the control processing as to the control order is reduced. In this case, the temporary storage capacity for the control order on the order queue buffer 4 is speedily decreased as a result and more control orders from a host device 1 can temporarily be stored on the order queue buffer 4 by the decrement, so that the throughput of the whole system is improved.

Abstract: PURPOSE:To improve an address indicating accuracy by a light pen, by varying an amplification factor of a bright line detecting signal detected by the light pen, and limiting the number of binary-coded bright line signals to several pulses. CONSTITUTION:In case a luminance of a CRT1 is varied, sometimes the number of pulses of a binary-coded bright line signal (d) is varied from an initial set value, and sometimes an address indicating accuracy is deteriorated by a light pen 2.
