Patent JP-H0454019-A (JP)
Title: Frequency synthesizer
Inventor: YAMAZAKI TOYOE
IPC: H03L7/18
Filed: 1990-06-21
Abstract: PURPOSE:To reduce a phase lock time at the time of changing a frequency by forming a phase locked loop with a voltage controlled oscillator, a programmable counter, a phase comparator, a loop amplifier and an adder and phase-locking the output of the voltage controlled oscillator with the output of a reference oscillator. CONSTITUTION:With an SW signal fed to a reset circuit 6, the reset circuit 6 outputs a reset signal R being a control signal synchronously with the output from a reference oscillator 3 to a programmable counter 2. The programmable counter 2 counts down the output frequency of a voltage controlled oscillator 1 and is controlled in phase with the reference oscillator 3 by the reset signal R, and outputs a signal with the same frequency and the signal is fed to the 2nd input section of a phase comparator 4. While the frequency setting state continues, the input of a loop amplifier 5 is opened. Thus, the time required for phase locking with an output of the reference oscillator 3 after the change in the frequency is decreased more than that of the conventional synthesizer.

Title: Charge pump circuit
Inventor: TAKAGI KOTARO
IPC: H03L7/107
Filed: 1989-06-27
Abstract: PURPOSE:To prevent C/N from being deteriorated and to prevent modulation distortion from being generated by composing a charge pump circuit of a constant current source and switching circuit, which switches the output current of the constant current source, and charging or discharging a loop filter with a constant current corresponding to phase difference. CONSTITUTION:An FET (Q3) is provided to charge a loop filter 6 by the constant current and an FET (Q6) is provided to discharge the loop filter by the constant current. The charge/discharge of these FETs (Q3, Q6) is controlled by phase comparing outputs U and D through FETs (Q4, Q5) for switching. Thus, a voltage E6 linearly proportional to phase difference DELTAtheta between signals R and V can be obtained from the filter 6. For example, the loop gain of a PLL can be adjusted by turning ON/OFF a transistor Q9 and changing intensity of a current i1 to be made flow to a terminal T1. Accordingly, by controlling this loop gain, the look-up time of the PLL can be shortened.

Title: Device and method for managing network
Inventor: HAMADA NOBORU
IPC: G06F13/14
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To reduce traffic for searching a network device. SOLUTION: In the case of searching a network device, a packet for search is executed once at the time of starting the search (S1301), the research of each device searched at the time of starting is repeated one by one at a prescribed interval (S1305). Consequently a situation where network traffic increases can be prevented by broadcasting the packet for search. Since the broadcast packet is periodically transmitted, the broadcast packet is successively transmitted to devices registered in a device table instead of updating the device table and only whether each device responds to the packet or not can be checked. Consequently the device table can be updated in a comparatively small network traffic.
