Title: Clock pule transmission circuit
Inventor: SEKI SHINSUKE
IPC: H04L25/03
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To automatically correct errors in the duty ratio (DF) of a clock in a receiver output. SOLUTION: Front and back edges of a clock in the output of a buffer 3 are inclined and a trapezoidal wave is generated in an RC time constant circuit 20. It is compared with a threshold V11 by a driver 6 and a pair of positive signal and negative signal are transmitted to a receiver 12. The receiver 12 differentially amplifies both signals and outputs a pair of positive signal V3 and negative signal V4. An RC integration circuits 21 and 22 select the DC components of V3 and V4, and it is transmitted to a transmission circuit 1 from buffers 23 and 24 through control transmission lines 25 and 26. The signals are received in buffers 27 and 28 and are inputted to a differential amplifier 30. Voltage corresponding to the error in DF of receiver output is taken out and the error voltage is integrated in an integrator 36.  It is given to the driver 6 as the threshold through a buffer 40, DF of driver output is changed in accordance with the magnitude of the threshold and the error in DF of receiver output is corrected.

Title: Phase-locked loop circuit
Inventor: MURAYAMA YUKIO
IPC: H03L7/183
Filed: 1980-09-01
Abstract: PURPOSE:To keep the stability of a loop, by changing the loop gain through the change of the power supply voltage of a phase comparator of a phase-locked loop PLL circuit according to the frequency dividing ratio. CONSTITUTION:A voltage controlling circuit 6 is connected to a variable frequency divider 2 of a PLL circuit. The circuit 6 recevies a signal applied to program terminals P0-P3 of a frequency divider 2 to deliver the signal of voltage VDD' to a phase comparator 3. The voltage VDD' is proportional to the frequency dividing ratio N, the sensitivity of the comparator 3 is proportional to the voltage VDD' and the loop gain is proportional to a prescribed sensitivity of a voltage controlled oscillator 5, then the loop gain is constant independently of the frequency ratio. Thus, even if the change in the frequency dividing ratio N is made greater, the loop stability can not be lost, the high-speed operation request to components can be eliminated and the manufacturing cost of the PLL circuit as a frequency synthesizer can be decreased.

Title: Data collection system of optical transmission system
Inventor: IWAI AKIRA
IPC: H04B7/24
Filed: 1985-06-03
Abstract: PURPOSE:To improve the data collecting efficiency by providing a line using state discriminating function by other station and transmitting a data with a standby time set differently from each station. CONSTITUTION:In case of line idle state, after the closing of squelch is con firmed, a CPU 2 sends a press signal to a radio equipment 1 to switch the equipment 1 into the outgoing state for data transmission. When the squelch is opened while the transmission trigger is applied, the CPU 2 does not send the press signal to the radio equipment 1 and awaits the squelch closing. In mobile stations A, B applied with a transmission trigger, the station A sends a data after a standby time t1 elapses. Further, since the station A transmits during the initial count of t2 (>t1) and the squelch is opened again, the mobile station B is in standby until the sending of the station A is finished. Thus, the collision of outgoing data by the station A, B is prevented.

Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To detect severance of a wire in a trailer side lamp by providing a wire severance detecting circuit through a trailer side circuit and the second relay for interlocking the output circuit of the wire severance detecting circuit with the tractor side circuit. SOLUTION: This device is wired from a power source B to a flasher unit 2 through a tractor side fuse 1 and is wired from the flasher unit 2 to a tractor side lamp 3 through the second relay 8. On a trailer side, this device is branch- wired from between the power source B and the tractor fuse 1 through a trailer side fuse 5, and is wired to the first relay 4 through a wire severance detecting circuit 7. If a trailer side lamp has wire severance, the wire severance detecting circuit 7 detects it to generate output current from an output-terminal 7-OP, and the second relay 8 is operated by output current to open the circuit between the flasher unit 2 and the tractor side lamp 3. It is thus possible for a driver to recognize wire severance if the trailer side lamp has wire severance.
