Title: Ozonizer
Inventor: MURATA AKIRA
IPC: C01B21/04
Filed: 1980-07-01
Abstract: PURPOSE: To improve the portability and to efficiently generate high density ozone by connecting the positive side of a high voltage transformer attached to the outside of a tightly sealed long cylindrical case to an electrode placed at a central part of the case and the negative side to a metallic band on the outside of an inner jacket tube.  
     CONSTITUTION: Dehumidified, dried and compressed air freed of unnecessary gases such as CO 2  and nitrogen by adsorption is fed into a tightly sealed long cylindrical case 1 with pressure resistance from the inlet 1a. The air flows into the space between an outer jacket tube 5 and an inner jacket tube 3, and it is introduced downward through a porous metallic band 4 wound around the tube 3 under discharge. During this time, the air takes a roundabout way and forms a turbulent flow by the resistance of the band 4 to increase opportunities for discharge contact. After passing through the band 4 the air generates high density ozone O 3  and is exhausted from the lower exhaust port 1b.

IPC: B01D53/72
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To rapidly and completely remove hydrocarbon consisting essentially of methane without the need for another catalyst, etc., by oxidation cracking the hydrocarbon in gas containing the hydrocarbon consisting essentially of the methane of high temperature by using ozone. SOLUTION: The previously formed ozone is added to the high-temperature gas in the case the hydrocarbon in the high-temperature gas >=37 deg.C containing the hydrocarbon consisting essentially of the methane is removed by oxidation cracking. At this time, the ozone is previously formed from air, oxygen-enriched air, oxygen as well as exhaust gases in which oxygen is included, etc. Such ozone is added to the gas containing the hydrocarbon consisting essentially of the methane. For example, the ozone is added to the gas exhausted from the cylinders of a gas engine to remove the hydrocarbon in the gases by oxidation cracking. The treated gases are supplied to a turbine to drive the turbine and are then discharged. The amount of the ozone to be added is most adequately regulated according to the temperature and velocity of the exhaust gases.

IPC: F02P5/155
Filed: 1982-05-28
Abstract: PURPOSE:To prevent excessive lowering of the engine speed at the time of applying abrupt braking, by advancing the ignition timing when the engine speed is lower than the idling speed. CONSTITUTION:When abrupt braking is applied by a driver depressing the accelerator pedal, the engine speed is lowered abruptly to a level lower than the idling speed. In this state, the level of the output of a comparator 85 becomes high, so that a transistor 82 is turned ON while a transistor 62 is turned OFF. Resultantly, a trigger signal is supplied to resistances 16, 17 and a thyristor 13 is turned ON, so that the engine is ignited through discharge of a capacitor 12. Therefore, the ignition timing is advanced. With such an arrangement, it is enabled to prevent excessive deceleration of the engine at the time of applying abrupt braking.

IPC: H04B5/02
Filed: 1994-04-28
Abstract: PURPOSE:To make a proximity radio data communication equipment small-sized and economical by using a double-current RZ pulse signal and transmitting and receiving it as a radio wave as it is without modulation/demodulation. CONSTITUTION:In a transmission/reception part S, a waveform conversion part 21 is provided between a signal processing part 3 and a power amplification part 5 instead of conventional carrier signal generation part and modulating part. The waveform conversion part 21 converts inputted binary data SD' into the double-current RZ pulse signal as a kind of a base band signal. A transmission antenna is directly excited by this base band signal to transmit a radio wave. In a reception part R, a waveform conversion part 22 which converts the double-current RZ pulse signal into a signal adapted to signal processing is provided between a waveform shaping part 11 and a signal processing part 12 instead of conventional demodulating part and carrier signal generation part. Thus, this equipment is made much more small-sized and economical as the whole than conventional because conventional carrier signal generation parts and relatively expensive modulation part and demodulation part are omitted and waveform conversion parts consist of small-sized and inexpensive IC logic circuits.
