Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To perform highly accurate wavelength control without complicating the wavelength detection system of a communication node by informing the communication node of control information obtained from a first communication system wavelength through a second communication system by a control node and controlling a wavelength to be outputted to a first communication system based on it and the wavelength information of the first communication system. SOLUTION: A wavelength control system 301 controls the light emitting wavelength of the wavelength variable LD 302 of a wavelength multiplex communication system based on the detected result of a wavelength interval detection system and a wavelength interval correction packet from a packet communication system reception part. At the time of starting light emission, an optical switch 318 is turned to the side of an optical multiplexer 319, and in the state of not performing transmission to an optical fiber, the wavelength of the wavelength variable LD 302 is set so as to turn the wavelength of the other communication node within the wavelength variable range of the wavelength variable LD 302 to a prescribed wavelength interval. Thereafter, the wavelength interval of the wavelength variable LD 302 and the adjacent wavelength is definitely held.  Also, wavelength multiplex communication system reception wavelength control is performed as well.

Title: Contact detector
Inventor: SAKURAI KOJI
IPC: G01B7/00
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To enable a contact detector to be used in various environments and to constitute a fail-safe safety system in a simple structure. SOLUTION: A contact detector 1 uses a flexible strain sensor 11 as a transducer. The sensor 11 is connected to a detecting member 16 which is displaced when a man or object comes into contact with the member 16 through a slider 15. When the member 16 is displaced, the electric resistance value of the sensor 11 varies and the strain of the sensor 11 in the direction of elongation can be detected. Prescribed tension is applied to the sensor 11 in a non-displaced state and the strain of the sensor 11 is detected from the variation of the electric resistance value from this state. Since the tension is preapplied to the sensor 11 in the above-mentioned way, the failure or abnormality of the sensor itself resulting from disconnection, coming off, etc., can be detected from the output signal of the sensor 11.

Title: Channel assignment system
Inventor: KUNO YUTAKA
IPC: H04W72/08
Filed: 1995-02-22
Abstract: PURPOSE: To exclude inefficiency automonously and distributingly when a dead channel discrimination level is fixed by deciding a threshold level of a dead channel discrimination parameter based on a dead channel discrimination function calculated from an interference history and a channel operating state. CONSTITUTION: A radio base station 2-a measures a reception level of an interference wave from peripheral cells 2-b, 2-c at all times and calculates a dead channel discrimination level based on a rate of the number of channels whose reception level exceeds a fixed value to entire channel numbers. When a call is arisen, a channel with an interference wave level below the dead channel discrimination level is selected for communication. When traffic is increased, through the variation of the dead channel discrimination level, the channel operating condition is relaxed and when the traffic is decreased, the operating condition is made tighter. Thus, when the traffic of a peripheral cell is small, the dead channel discrimination level is tight and a channel with excellent quality is strictly assigned, then the channel with quality in response to the traffic is assigned.

Abstract: PROBLEM TO BE SOLVED: To lower the level of radiation noise by communicating a signal having no repeatability substantially in a period of intermitting the data communication, when a serial data communication is intermitted after establishing the synchronization of a clock between a transmitter side and a receiver side. SOLUTION: A synchronous signal is transmitted for a prescribed hour in starting the operation of a transmitter and a long transmission of a synchronous signal is continued for a time sufficient for a PLL circuit of surely phase locking. The transmitter reads out random numbers written thereon from a random number table TBL one by one, serially transmits it by a parallel serial converter PSC, and transmits the serial signal having the synchronous signal distributed and inserted in the random number data during no transmission data. After that, when an X-ray CT starts scanning, the data is transmitted. A receiver judges the presence/nonpresence of the synchronous signal, judges the presence/nonpresence of the data, and when it is judged to be the data, it is sent to a data collection buffer 5.
