Title: Device for controlling generation amount of ozone
Inventor: NAKANO YOSHINORI
IPC: C01B13/11
Filed: 1993-01-28
Abstract: PURPOSE:To reduce the loss of a transformer by installing a means between an AC electric source and the transformer, the means producing voltages having a constant integrated voltage value against variations in the frequencies of the electric source. CONSTITUTION:The voltage commands of a PWM inverter are formed so that a section containing zero voltage is placed in a cycle of each frequency such as 500Hz or 1000Hz in response to the voltage wave shape of the maximum frequency 2000Hz. Thereby, the total areas of the voltage wave shapes of the frequencies are equal to each other. Since the integration value of the voltages can be kept constant even when the frequency is changed by any method, the magnetic flux of the transformer is kept constant, and the transformer can easily be designed. The loss of the transformer can also be reduced. Further, even when the voltage wave shape is changed into any shape, the amount of produced ozone is not changed, and the transformer can sufficiently be controlled to the frequencies.

IPC: H04N9/84
Filed: 1981-01-30
Abstract: PURPOSE:To reproduce and deliver a color video signal of an SECAN system of a high  quality with a simple circuit constitution, by processing a synthetic color signal reproduced out of a recording medium with a jitter and accordingly reducing the phase  shift to completely eliminate the jitter. CONSTITUTION:A synthetic color video signal containing a jitter which is reproduced  out of a recording medium is supplied to an input terminal 1. This video signal is applied to a delaying circuit 10 and a frequency converter 11, and the frequency of the  signal is converted by the difference to a prescribed frequency. Thus the phase shift is  reduced for a carrier chrominance signal supplied from a subtracter circuit 13 forming  a comb-shaped filter. The output of the circuit 13 is supplied to an automatic phase  control circuit 24, a demodulating circuit 28, etc., and a demodulating color subcarrier which is synchronous with the color burst signal in the carrier chrominance signal with  elimination of the phase shift caused by the jitter is delivered from the circuit 24 to be  applied to a switch circuit 27. Then the subcarrier waves having the phases different  of each other by 90 deg. are applied to the circuit 28 with every 1H. Thus the fluctuation  of the hue due to the jitter can be completely eliminated. In such way, a color video  signal of an SECAN system is obtained with high quality through a simple constitution.
