Title: Optical reception circuit
Inventor: NAITO SEIGO
IPC: H04B10/40
Filed: 1986-11-21
Abstract: PURPOSE:To prevent the occurrence of a nose pulse by providing a histeresis width setting change circuit varying the hysteresis width of a comparator circuit in response to the amplitude of a current flowing to an avalanche photodiode (APD). CONSTITUTION:When an optical signal is inputted and a voltage drop of a resistor 1 is increased, after the APD bias voltage is amplified by an error amplifier 9, the voltage is inputted to a feedback loop of a hysteresis width setting circuit 6 via an input circuit 10. Thus, the hysteresis width set by the circuit 6 is subjected to change and the width is decreased. When no optical input comes conversely, since the voltage drop across the resistor 1 is decreased, the hysteresis is increased. When the bias voltage of APD is increased and a multiple factor is increased in this case, the hysteresis is increased and a comparison voltage is higher. Thus, even if noise included at no signal is increased, no noise pulse is generated in the output of the comparator circuit 7.

Abstract: PURPOSE:To prevent corrosion at a dust collector or a duct and a blower discharging gas processing system by a method wherein SO2 and H2O in the discharged gas of sinterring machine are measured, a rapid metal corrosion starting temperature is calculated in response to a result of measurement and a discharged gas temperature in the discharging gas processing system is controlled to be higher than this starting temperature. CONSTITUTION:A sinterring machine is comprised of a raw material feeding hopper 1, a sinterring machine pallet boggie 3, an air box 4, a boiler 5, dust collectors 6, 12, and discharged gas suction blowers 19, 20. Sensitive heat of the discharged gas at a rear half part of the sinterring machine is recovered by vapor at a boiler 5, resulting in that the temperature is lowered at the dust collector 6, sulfuric acid dew formation is produced within the dust collector 6 and so the dust collecting facility is apt to be corroded. In view of this fact, an SO2 meter 13, an H2O meter 14 and a thermometer 15 are mounted at an outlet side of the dust collector, a metal rapid corrosion starting temperature is calculated at 10 in reference to the SO2 value and H2O value.

Title: Water-droplet detector
Inventor: SUGIURA MASUO
IPC: G01N5/02
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect a water droplet even for opaque material by a constitution that a piezoelectric vibrator is attached to the rear recess surface of a thin part formed by providing a recess part on the rear surface, and that the water droplet is detected by utilizing a resonance phenomenon. SOLUTION: When a driving signal is intermittently outputted from an oscillating circuit 7, the signal is supplied to a piezoelectric vibrator 4 through a resonance circuit 8. A thin part 3 is vibrated at a natural resonance frequency f0 . Then, the vibration of the thin part 3 is transduced into the electric signal with the vibrator 4 during the stopped period of the supply of the driving signal, and the circuit 8 is operated. At this time, when the circuit 8 is resonated at the frequency f0 , the impedance of the circuit 8 becomes the minimum value, and the current flowing from a positive-side terminal 15 to the circuit 8 and the circuit 7 becomes the maximum value. In the meantime, when a water droplent W is attached on the thin part 3 and the mass of the vibrating system is increased, the vibrating frequency returning to the circuit 8 from the vibrator 4 is displaced.  As a result, the impedance of the circuit 8 becomes high, and current of a current detector 14 is decreased. The detected current is monitored by a control part 13. When the decreased amount is larger than a reference value, the attachment of the water droplet W is detected, and a water-droplet remover 16 is operated.

Title: Light wave length converting element
Inventor: SHINOKURA KIICHIRO
IPC: G02F1/35
Filed: 1990-10-18
Abstract: PURPOSE:To obtain the steady output of the second higher harmonic wave corresponding to the variation and dispersion of the input of the basic wave by making the matched wave length of an optical wave directing path type wave length converting element variable. CONSTITUTION:A light wave length converting element is formed of an optical wave directing path type wave length converting element 10 which is composed of a core 11 formed of non-linear optical crystal whose variation caused by temperature change of refractive index is above 1X10<-4>/ deg.C and a clad 12 coming into contact with the core, and converts the primary ray incident upon the core into the secondary higher harmonic wave having half-wave length, and a thermoelectric element element 20 being in contact with the element 10. A Peltier element used for the element 10 can minutely control its own heating and cooling corresponding to the direction of applied current. Since the potassium niobate of the element 10 has high temperature dependency in the variation of the refractive index, the temperature of the element 10 can be controlled using the Peltier element 20 for converting the matched wave length of the primary incident light. For example, in the case of the conversion of the wave length of the output ray of a semi-conductor laser utilized for an optical memory, the output fluctuation, which is caused by the wave length fluctuation of the laser ray in a wave length converter, of the second higher harmonic wave can be lessened.

Title: Carbonic heating element
Inventor: SUDA YOSHIHISA
IPC: H05B3/14
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To improve an aging deterioration characteristic or thermal stability by including hardly graphitinized carbon and one ore more than two kinds of metal or half-metal compounds and keeping the average distance between the facets of the hardly graphitized carbon not less than a specific length even after processing it at a certain temperature. SOLUTION: A composition that is transformed into hardly graphitized carbon after baking and a metal or half-metal compound are thoroughly mixed by using a kneading machine, the obtained mixture is formed into a designed shape by a forming technique such as a vacuum forming machine. Next, the formed body is heated to raise its temperature in the atmosphere of inert gas such as nitrogen or under vacuum and is thus carbonized. In this case, the hardly graphitized carbon keeps the average distance between its facets not more than 3.42 Åeven after processed at 3000 deg.C.  By performing a process to change the formed body into a carbon precursor by heating it under the presence of oxygen before baking it and thereby causing a crosslinking reaction, the hardly graphtized carbon can be provided by using, as the starting substance, a resin that is changed into easily graphitized carbon after baking, and thus, the heating value can easily be controlled by the application of set current and potential.
