Title: Communication network system
Inventor: KADO YOICHI
IPC: H04W16/26
Filed: 2000-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a communication network system that can prevent deterioration in a radio wave environment and build up a network at a low cost. SOLUTION: Nodes used for transmission of a packet signal include a mobile node W and fixed nodes L-P. The mobile node W is a node moving on a route Rt1 and the fixed nodes L-P are nodes fixed along the route Rt1. A packet signal is transmitted to a destination node via the mobile node W and the fixed nodes L-P. That is, the packet communication among the fixed nodes L-P is conducted by way of the mobile node W. Thus, it is not required to make communication among the fixed nodes by utilizing a radio wave with a strong electric field so as to prevent the radio wave environment from being deteriorated. Since it is not required to install a cable among the fixed nodes, the communication network can be built up at a low cost.

Title: Capacitor microphone device and its repeating device
Inventor: IKEDA MASAHARU
IPC: H04R19/04
Filed: 2000-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce the noise output of a high-frequency signal over a wide carrier frequency range by connecting one end of a bypass capacitor to the signal output terminal of an amplifying means and the other end to the common output terminal of the amplifying means, and inserting series resistances between the signal output terminal of the amplifying means and a device output terminal, and the common output terminal of the amplifying means and a device common output terminal. SOLUTION: A capacitor microphone unit 10b has a series resistance 24 inserted between the drain of an FET 19 and a microphone signal output terminal 22. For example, the equivalent series resistance of the bypass capacitor 21 is <=1 Ω, so a resonance current between a microphone signal output power transmission line 31 and the bypass capacitor 21 is reducible to 1/10 to 1/100 by setting the series resistance to tens to hundreds of Ω and the high frequency voltage applied to the drain of the FET 19 is also reducible to 1/10 to 1/100. Consequently, noise generated with a high-frequency signal radiated or conducted from the transmission part of a radio device can be suppressed low.

Filed: 2000-07-07
Abstract: PROBLEM TO BE SOLVED: To obtain an optical filter having flat group delay in the effective band by forming two serial Bragg gratings such that each filter has linear chirp opposite to the other filter. SOLUTION: The light signal passes a light guide Gin to enter an optical circulator C3 through a port P1, is reflected by a first filter FBGA in the band of the filter, and returns with group delay added by the linear chirp of the FBGA filter to a port P2 through a guide Ga. Then the signal is sent through a port P3 and a guide Gb to a second Bragg filter FBGB having opposite linear chirp to the first filter FBGA. The light is reflected by the second filter FBGB to the port P3 of the circulator C3 through the guide Gb and supplied to a guide Gout from the circulator C3 through a port P4. Two gradients of the two filters offset each other to produce zero gradient in the output signal, and the group delay is flat in the band of the filters.
