Filed: 1985-05-16
Abstract: PURPOSE:To moderate the accuracy of a fixed type reflecting mirror and to reduce the size of the title device by arranging three reflecting mirrors between an image formation lens and an exposing part, fixing one of them and moving other two in a prescribed direction to execute scanning exposure. CONSTITUTION:The 1st reflector 11 is fixed between the image formation lens 6 and a slit exposing plate 22 and the 2nd and 3rd reflecting mirrors 14, 15 are arranged so as to be unitedly reciprocated in the arrow A direction with 45 deg. angle formed by respective reflecting surfaces. At the time of printing under said constitution, the movable mirror 12 is receded to a position shown by a broken line and the 2nd and 3rd mirrors 14, 15 are moved to exposure starting positions in the arrow A direction and then moved in the reverse direction to execute scanning exposure on a photosensitive drum 21. Since the 1st reflecting mirror 11 is fixed, its high accuracy is not required and the size can be reduced. In addition, the size of the whole device can be reduced because of the use of the leading optical path.

Title: Auto-focus camera
Inventor: OGAWA YUKIO
IPC: G02B7/28
Filed: 1981-07-06
Abstract: PURPOSE:To shorten the time from release to opening and closing of a shutter in accordance with the distance to an object, by utilizing the fact that the time from the output of a range finding signal to the stop of running of a photographic lens at a prescribed position is different in accordance with the object distance and varying the time to the next sequence in accordance with the range finding signal. CONSTITUTION:A signal (h) which sets the time to the next sequence is applied to a decoder DC from a range finding operation circuit RF in accordance with a range finding signal (b) which is generated when the distance to an object is detected, and an output (i) is applied to a timer TM. Thus, the time from the start of running of a photographic lens to the start of the next sequence (for example, opening and closing of the shutter) is determined. The signal by which the timer TM starts counting is generated simultaneously with the signal, by which the photographic lens starts running, from a sequence controlling circuit SQ.

CONSTITUTION:Differential amplifier circuits 1 and 6 detect respective difference of the phase error control signals 101 and 102 of channels P and Q, and output a carrier control signal 103 and a phase error differential signal 107, respectively. The levels of the signal 107 are compared, and a high level and a low level detection signals are synthesized, and the asynchronism detection signal 105 of a carrier is outputted from a synthesis circuit 9, and is inputted to a synchronism controlling oscillation circuit 10. The circuit 10 performs an oscillation operation and an oscillation stop operation based on the signal 105. The output signal 103 of the circuit 1 and a synchronism controlling oscillation signal 104 that is the output of the circuit 10 are inputted to a carrier reproduction circuit 5, and the circuit 5 outputs a carrier signal 106 in which synchronization is controlled based on both signals 103 and 104. By such interaction, the detecting time of the asynchronous state can be shortened, and it is possible to set the optimum preset adjustment on the change of the modulation/ demodulation system.

Title: Error correction decoder and error correction decoding system
Inventor: NARA HIDEAKI
IPC: H03M13/23
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To improve the error correction decoding capability, without increasing calculation amount. SOLUTION: In this decoder, a demodulation means 1 demodulates reception data and a Viterbi decoding means 2A decodes the received data into a bit series by using the Viterbi algorithm, based on soft discrimination information generated at its demodulation and provides reliability information to each bit of the bit series at the same time. Then a CRC means 3 applies CRC to the decoded bit series to discriminate whether or not an error has been detected and provides an output of the bit series as decoded data when on error is detected, and conducts bit inversion in the order of decreasing total sum of the reliability information of the bits for bit inversion until no CRC is detected when an error is detected. Thus, the possibility of the case of misdetecting an error is reduced, and the calculation amount is also reduced.
