Title: Digital phase comparing apparatus
Inventor: NIITSUMA SUSUMU
IPC: G01S1/30
Filed: 1982-09-13
Abstract: PURPOSE:To automate phase matching notch control, by a method wherein an actually used 0.2f-pulse is selected in a Decca main station apparatus and the phase difference pulse amplitude with all 0.2f-pulses is counted by a high frequency signal to judge phase difference. CONSTITUTION:The controllers 9-1-9-3 of a signal generating part 9 are selected through an actually used 0.2f-pulse selecting circuit 21 responding to a change-over apparatus selecting part 27 and an actually used 0.2f-pulse is selectively outputted. This pulse is compared with the 0.2f-pulses from the controllers 9-1-9-3 through a compared pulse selecting circuit 22 and a phase difference detecting circuit 23 outputs a phase difference pulse. In this case, phase difference pulse amplitude is counted by a base-24 system counter 24 for counting a 24f- signal with high frequency while phase difference is judged by the comparison with the set value of a region judging circuit 25 and the controllers 9-1-9-3 are controlled corresponding to judge output to automatically perform phase matching notch control.

Title: Adjuster for high frequency gain
Inventor: OOHASHI YOSHIMI
IPC: H03G3/10
Filed: 1977-12-26
Abstract: PURPOSE: To increase the adjusting range for high frequency gain by making variable the input electrode voltage of the high frequency amplifying active element with a variable resistor, and by inserting a diode between the junction point and the input electrode of the post stage amplifying active element.  
     CONSTITUTION: When the voltage across the high frequency amplifying FETQ1 is decreased with the variable resistor R' 2 , the amplification factor Q1 is inwered. If it is lowered less than the base voltage of frequency mixing Q2, forward current flows to the diode D1 and the potential of Q2 is also decreased as the gate voltage of Q1. Accordingly, the amplification factor of Q2 is lowered and the operation can be close to the stop state.

Abstract: PURPOSE:To detect the extent of deformation of an object to be drafted with high precision by providing the object to be drafted with through-holes and providing a stage with fixed pins and moving pins engaged with through-holes. CONSTITUTION:A printed board 1 is raised by a piston 30 and through holes 2-5 are pierced by corresponding pins 6-9. If the positions of through-holes 3-5 other than the reference through hole 2 are shifted with respect to the position of the reference through-hole 2 because the printed board is deformed, the slopes of chambered parts of moving pins 7-9 are brought into contact with through-holes 3-5 and they are inserted there eccentrically. Positional deviations of them are detected by positional deviation detectors 40-43 and are given to a controller 44, and the controller 44 detects the deformation of the printed board 1 as expansion and contraction rates in (x) and (v) directions and corects the clock rate of drafted data IMDA in accordance with this deformation and gives the corrected clock rate to an optical beam modulating and scanning system 45 together with a rotating polygonal mirror driving signal PDR and corrects a stage driving signal SDR in accordance with the deformation and gives it to a stage driving circuit 46. Thus, a pattern corrected in accordance with the deformation of the printed board 1 is drafted by compensated raster scanning.

Title: Facsimile equipment
Inventor: KOIZUMI HIROZOU
IPC: H04N1/32
Filed: 1983-08-31
Abstract: PURPOSE:To make it possible to receive picture data even if original size information is not received yet, by outputting original size information corresponding to counted decoded picture signals if original size information is not received yet in a facsimile system. CONSTITUTION:If original size information Z is not received yet, a signal S is received by a receiving buffer 7, and a discrminating part 12 generates a control signal to start a counter 13 when a line end code EOL in the receiving buffer 7 is detected. The number of decoded picture signals decoded by a decoding part 14 is counted by the counter 13. A discriminating part 15 checks the counted value of the counter 13 and discriminates A4 size when this value is 1,728 bits and discriminates B4 size when it is 2,048 bits. An output part 9 outputs decoded picture signals G in a buffer 16 as signals of an A4 or B4-size original in accordance with this discrimination signal. Thus, even if information designating the original size does not reach the reception side, normal reception of FAX is possible.

Filed: 1986-07-09
Abstract: PURPOSE:To reduce the number for writing to an EAROM and to improve the reliability by rewriting the data of a RAM once when the data of the EAROM is rewritten and rewriting the data of the EAROM by the data of the RAM when a prescribed command is applied. CONSTITUTION:In the ROM (EAROM) capable of electrically rewriting which is disposed in an information processing equipment together with the random access memory (RAM), when the data of the EAROM14 is rewritten, the contents of the EAROM14 are not directly rewritten but the data on the RAM13 is once rewritten, thereafter, an EAROM writing command is applied from an operation computer 3 or a monitor CRT4 according to the necessity and written. Accordingly, the number of times for writing the data to the EAROM14 is remarkably reduced, thereby, the reliability of the EAROM14 can be maintained. Even when an error is produced immediately after the data is written, since a CPU refers to the data on the RAM, the normal operation of the equipment is assured.

Title: Recording and reproducing device for television broadcast
Inventor: FUJITA TAKASHI
IPC: H04N5/44
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To perform the CM(commercial) skip with no malfunction even when the BF(black frame) durations differ for every program by always measuring the BF duration between the CM of a program under reproduction and the program main part to record the measured least duration as the threshold and carrying on the CM skip until the BF duration longer than the threshold is detected. SOLUTION: A BF sampling circuit 7 and a silence part sampling circuit 8 sample both BF and silence parts from a reproducing signal PB and output the BF silent parts via an AND circuit 9. A CM-main part BF silent part decision circuit 12 decides the presence or absence of a CM-main part BF silent part based on the information on a BF-BF period measurement circuit 10 and a BF silent part period measurement circuit 11 and stores the shortest BF silent part period in a memory 13. The CM skip actions are carried on until the circuit 11 detects a BF silent part longer than the shortest BF silent part period of the memory 13. Thus, the accurate CM skip is possible even though a cassette is once taken out after the picture recording.

Filed: 1982-09-14
Abstract: PURPOSE:To reduce the switch noise without using a switch having a small amount of switch noise, by supplying the output of a buffer amplifier to a discriminating circuit only in a receiving period which is set for reception of a received burst signal. CONSTITUTION:A transmitted burst signal S is supplied to a receiving circuit 11; while a received burst signal R sent from a transmission line 8 is supplied to a receiving circuit 11 via a transformer 9. At the circuit 11 a buffer amplifier 13 amplifies and then delivers both signals S and R. A switch 12 conducts only in a receiving period of a high level of a control circuit 15 to delete the amplified signal S and supplies only the signal R to a discriminating circuit 14. In this case, the noise due to the switch 12 is supplied to the circuit 14. However, the noise is satisfactorily reduced compared with the level of the amplified signal R since the switch 12 is provided to an output stage of the amplifier 13.
