Title: Ozone generator
Inventor: YAMAZAKI TAKESHI
IPC: C01B13/11
Filed: 1988-12-20
Abstract: PURPOSE:To obtain an ozone generator which is readily controlled in its dimensional precision and can efficiently generate ozone by arranging a plurality of stratiform pores through the ceramic body in parallel alternately for insertion of electrodes and discharge space to generate ozone. CONSTITUTION:In the above-stated ozone generator, an alternating voltage is loaded between the second electrode 6 and the first electrode 4 to cause silent discharge in the discharge space 5. The silent discharge converts the oxygen in the air into ozone in the space 5. In other words, air is sent in the spaces 5 with a blower 8 to generate a large volume of ozone and the ozone is sent into pipe 7. During the operation, the discharged power is converted into heat more than 90%, but ceramic tubes are used in the generator to keep the dimension of the pores 2 in high precision, because the ceramic tubes has excellent heat resistance, high thermal radiation efficiency and extremely reduced thermal expansion of the ceramic. Thus, the local discharge can be prevented and steady discharge is maintained to continue high-efficiency ozone generation.

Abstract: PURPOSE:To increase the efficiency of an information processing by attaining the coupling between modules by means of an arbitrary bit pattern at a short data length. CONSTITUTION:Data 2 exchanged between modules A and B are expressed by a high level data link HDLC format. When the module B is called from the module A and the information processing is carried out, the address of a bit pattern to indicate the module B on the module A side and a parameter to be delivered are added before and after flag patterns 1 and 2, and sent on the module B side. The module B side is activated by an address part 01, reads a parameter 64, and carries out the processing. Thus, since the exchange between the modules is attained at the short data length and with an arbitrary byte expression, the information processing can be made efficient.
