Title: Deodorizing method of malodorous gas
Inventor: YAIDE NORIHIRO
IPC: B01D53/77
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To improve the removing rate of methyl sulfide and methyl disulfide by deodorizing a malodorous gas as a deodorization object by a packed tower type biodeodorizing method and thereafter, deodorizing the gas by a liquid dispersion type gas discharging method using an active sludge suspension. SOLUTION: In a packed tower 1 in a first process, a malodorous gas is brought into contact with a packed layer 3 making microorganisms which decompose the malodorous component in a wet state, stick and is deodorized. In this process, hydrogen sulfide in the malodorous gas is first biologically deodorized. As a result, a basic gas such as ammonia is absorbed and removed by the produced sulfuric acid at the same time. In a packed tower 1' in a second process, methyl sulfide or methyl disulfide remaining in the gas treated in the first process are removed by a scrubber method using an active sludge suspension kept neutral. In this process, methyl sulfide and methyl disulfide are decomposed by using the liquid which is prepared by suspending active sludge easily obtainable from a reaction tank of an aerobic biological treating facility for waste water.

Title: Communication control equipment
Inventor: HONDA TOYOTA
IPC: H04L5/16
Filed: 1986-09-19
Abstract: PURPOSE:To connect equipments to a bus as many as possible by closing a switching means only for a previously fixed period after transmitting/receiving a signal pulse on a transmission line to remove influence due to inductance of a transformer. CONSTITUTION:Current in a coil is made to flow into a resistor 206 in a reverse direction at the time of opening a switch 202 and the product of a current value and a resistance value at that time becomes a back swing voltage. Therefore, the back swing voltage is reduced by equivalently reducing the resistance value of the resistor 206 at the time of opening the switch 202. Namely, a switch 204 is connected in parallel with the resistor 206, and after opening the switch 202, the switch 204 is closed for a fixed period. Consequently, the reliability of communication is improved and equipments more than ordinary ones can be connected to the bus by using the same transformer.

Filed: 1985-10-04
Abstract: PURPOSE:To obtain a voltage variable oscillator whose oscillation output gain is stable within a wide variable frequency band by correcting the fluctuation of oscillation output gain with the amplitude frequency characteristic of a surface acoustic wave element. CONSTITUTION:Voltage controlled variable gain elements 2a, 2b are connected to two output terminals receiving different phases of a surface acoustic wave element SAW 1, the vector sum of the outputs is amplified by an amplifier 3 and the result is fed back to an input terminal of the element SAW 1. In controlling the gain of each variable gain element so a to make the sum of gains constant, when a signal of a prescribed amplitude is inputted to each variable gain element, the oscillation output has a characteristic that the output is minimized at the center frequency f0 (the gain of two variable gain elements is identical at this stage) of the variable frequency band and increased as the frequency is deviated from said center frequency. Thus, in selecting comb-line electrode pair number o the element SAW 1 using normal type electrodes where the amplitude is decreased as the frequency is deviated from the center frequency properly, the voltage variable oscillator whose amplitude frequency characteristic is made flat is obtained.

Title: Silicon nitride powder improved in its surface characteristics and production thereof
Inventor: URURIKE PITSUTSUAA
IPC: C01B21/068
Filed: 1989-08-29
Abstract: PURPOSE: To obtain a silicon nitride having a total oxygen content less than 1.8 wt.% without allowing undesirable fluorine ions to exist on its surface layer, by firing Si 3 N 4  powder having a low oxygen content under specific temp. and time conditions in an oxygen-contg. atmosphere.  
     CONSTITUTION: The Si 3 N 4  powder having the total oxygen content of ≤0.4 wt.% is annealed for 15 to 90 minutes at temperatures of 700 to 1200°C in the oxygen-cong. atmosphere. The Si 3 N 4  powder having the total oxygen content less then 1.8 wt.%, the ratio of the surface oxygen content to the total oxygen content of more than 65% and the fluorine content less than or equal to 35 ppm is thus obtd. The Si 3 N 4  power having the fluorine content on the surface of 0.1 atm.% or lower is more particularly adequate. The powder having the oxygen content less than or equal to 0.4 wt.% reacts extremely slowly in oxidation and hydrolysis reaction and, therefore, the increasing of the oxygen content of the surface up to a specified level is technologically simple.
