Title: Processing system of light transmission data
Inventor: NISHIDA MITSUHIRO
IPC: H04B10/07
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent equivalent series data from being transmitted to a downstream transmission path irrespective of the scramble processing timing of a transmitting part by replacing the equivalent series data by fixed data and transmitting to the light transmitting part of the terminal of the downstream transmission path even if the light receiving part of the terminal of an upstream transmission path receives the equivalent series data. SOLUTION: When the equivalent series data dc of the receiving data d1 is transmitted to an optical communication equipment 6 in the case of causing the abnormal state of the upstream light transmission path 11 , a 0/1 series detecting part 341 detects the receiving data d1 , converts into the fixed data dF1 and transmits it to the light transmitting part 22 of the downstream light transmission path 12 . The transmitting part 22 performs the prescribed scramble processing and converting the fixed data into transmission data d3 , and transmits it to the downstream light transmission path 12 .  Thus, a clock extracting processing and the scramble processing are certainly executed by a light receiving part in a light receiving device, the signal is restored to the fixed data dF1 and transmitted to the receiving terminal, and the occurrence of abnormality in an optical transmission system is recognized. Thus, the influence of the abnormal state occurred in the upstream light transmission path 11 to the downstream light transmission path 12 is prevented.

Title: Burner equipped with supersonic atomizer
Inventor: NAKAYAMA KOJI
IPC: B05B17/06
Filed: 1989-11-30
Abstract: PURPOSE:To let both ignition characteristic and combustion characteristic to coexist by providing a clearance between a nozzle main body and an air flow swirling board and mounting the nozzle main body and a lighting bar to a combustion outer cylinder. CONSTITUTION:This combustion device is provided with a nozzle main body 12 and an oscillator horn 15 fitted into the nozzle main body where a clearance is provided between the nozzle main body and an air flow swirling board 10. The nozzle main body and a lighting bar are mounted with a combustion outer cylinder 2.

Since the fuel flows from the fuel vaporizing chamber B directed at a combustion chamber A by way of an air aperture 3e, reversing its flow through a long flow passage, the primary air is uniformly mixed with the fuel so that complete combustion may be available with blue flames inside the combustion chamber A. It is, therefore, possible to satisfy the coexistence between both ignition characteristic and combustion characteristic.
