Title: Synchronizing sampling circuit
Inventor: NISHIGORI YOSHIHISA
IPC: H04N19/85
Filed: 1988-08-09
Abstract: PURPOSE:To attain sampling in synchronism with a burst signal of a composite video signal by generating a sampling value series from an address whose incremental value is varied in response to plural counter outputs counting a clock of 13.5MHz with a subcarrier generating circuit. CONSTITUTION:A composite video signal is inputted to a terminal 1 and sampled by a clock generated from a voltage controlled oscillation circuit (VCO)7 at an A/D converter 2. The frequency of the clock is 13.5MHz. The subcarrier generating circuit 8 counts the clock of 13.5MHz by counters 15, 16, 17 and the output of an address counter 9 varying the sum by a sum selection circuit 18 in response to count signals Sa, Sb, Sc is given to a ROM 10 and the sampling value series generated from the ROM 10 is sent to a multiplier 4. The multiplier 4 multiplies the result with a burst signal extracted from a burst gate 3 to obtain a phase error and the error is fed back to the VCO 7 via a D/A converter 5 and an LPF 6. Thus, the sampling is attained synchronously with the burst signal in this way.

Title: Detector for time when radio waves are irradiated
Inventor: KIJIMA TAKESHI
IPC: G01R29/08
Filed: 1981-12-04
Abstract: PURPOSE:To perform detection surely even when a receiving signal has attained a saturation level by detecting that the value obtained by multiplying the number of hits of the receiving signal in a specified time and the max. value of amplitude data attains the max. value. CONSTITUTION:The radio waves from a receiver 62 are subjected to threshold discrimination with a level discriminating circuit 63, and the video signal larger than the threshold level is applied to an analog-digital converting circuit 64 and a counter 65. A multiplier 68 multiplies the max. value of the amplitude of the video signal in a specified time detected with a peak holding circuit 66 and the number of hits in a specified time counted with a counter 65, and applies the multiplied value thereof to a detecting circuit 69 for the time when radio waves are irradiated. In a peak detecting circuit 692, the multiplied value in the central part of a storage area and the multiplied value at both ends of the central part are compared successively, and when the multiplied value of the central part is largest, the time when the radio waves are irradiated is detected and a trigger signal is led out.

Title: Communication device
Inventor: IKEGAMI NORIKO
IPC: H04B1/00
Filed: 1983-10-24
Abstract: PURPOSE:To understand accurately the reception state of a station at the remote side independently of the absence of an operator of the remote side station, by sending the reception contents back to the transmission station from the reception station, and comparing the received contents with the transmitted contents at the transmission station to confirm the coincidence. CONSTITUTION:A printed sentence is read by an optical character reader 1, and read- out character signals are recorded to a floppy disk device FD2 and at the same time sent to a reception station 20 via a transmission circuit 3 and a cable 14. The transmitted character signals are written to an FD23 via a reception circuit 22. The information on the FD23 is transferred directly to an FD24 and recorded there. A termination detecting circuit ED26 detects a transmission end signal sent from a transmission station. In this case, the contents of the FD24 are sent to a reception circuit 5 via a transmission circuit 24 and the cable 14. The circuit 5 sends the signal to a discriminating circuit 7 and at the same time starts a reproduction indicating circuit. Then the contents of the information transmitted from the FD2 are reproduced and sent to the circuit 7. The circuit 7 performs comparison every character and discriminates the coincidence or dissidence. Then only a discordant area if detected is transmitted again to obtain the coincidence finally.

Abstract: PROBLEM TO BE SOLVED: To suppress the spurious due to a thickness tilt of a piezoelectric element in the shape of a vibration electrode for a thickness vertical containment type piezoelectric resonator by adding a rectangular vibration electrode to a piezoelectric element that has a tilt in its thickness direction. SOLUTION: A piezoelectric resonator 8 consists of the rectangular vibration electrodes 2 and 3, the extraction electrodes 4 and 6 and the connection electrodes 5 and 7 which are formed on both opposite main surfaces of a piezoelectric element 1.
