Title: Sweep fsk receiver
Inventor: KAWAI KAZUO
IPC: H04L27/14
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a sweep frequency shift keying (FSK) receiver with which a residual central level error at the time of capturing a signal through the frequency sweep of a local oscillator can be almost set to zero even in the case of remarkably accelerating frequency sweeping when receiving a packet FSK signal having a section to send out a central frequency in the head through a receiver having a frequency sweeping function. SOLUTION: Concerning this receiver, a converting point detector 8 detects the time point when a demodulated base band signal at a central frequency outputted from a central frequency detector 4 crosses zero through a converter by frequency sweeping due to a variable frequency oscillator(VFO) 13. At that time point, a sweep voltage is held and the above weep voltage is corrected by a correction voltage from a correction signal generating circuit 9. Thus, over quantity corresponding to sweeping speed and the cyclic delay time of a system is corrected.

IPC: H04W60/04
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To reconnect to an opposite user with which a speech has been made after restoration of a fault in a radio channel. SOLUTION: In the case that a mobile communication exchange station C detects a fault in a radio channel for a communication call, the mobile communication exchange station C inquires of a location register V about whether or not reconnection is allowed or a wait time for reconnection and holds a speech channel with an opposite user X when the reconnection is allowed and releases a channel for a mobile set S only. The mobile set S that detects the fault of the radio channel during the communication conducts release processing and makes a position registration request to a mobile communication network M at the detection of restoration of the radio channel. Then the location register V sends a connection request to the mobile communication exchange station C by using the position registration processing for a radio channel restoration cause to the mobile set S. After receiving this reconnection request, the mobile communication exchange station C applies the processing equal to the call reception processing to the mobile set S from the call storing the speech channel with the opposite user X to restore again the speech channel with respect to the opposite user X by the mobile set S.

Title: Gas combustion apparatus
Inventor: YAMAZAWA NAOYUKI
IPC: F23D14/18
Filed: 1991-06-29
Abstract: PURPOSE:To easily ignite fuel-air mixed gas and automatically extinguish flame in flaming combustion. CONSTITUTION:Small holes 12 are provided on the circumferential face of a combustion cylinder 5. A cover 13 is attached around the periphery of the combustion cylinder 5 to form a narrow annular passage 16 between the circumferential face of the combustion cylinder 5 and the inner face of the cover 13. When mixed gas is burned forming a flame in the combustion cylinder 5, the greater part of gas in the combustion cylinder 5 is discharged through paths 20 of a low combustion catalyst 17 and an exhaust port 21, however, some part of gas is directly discharged outside through the small holes 12 and the passage 16. Therefore, the gas flow in the combustion chamber 5 becomes smooth, resulting in an easy ignition of mixed gas. When the combustion chamber 5 is heated by the heat of flaming combustion, the gas flow in the passage 16 becomes uneasy and conditions of flaming combustion in the combustion chamber 5 is destroyed, leading to automatic extinction of the flame.
