Abstract: PURPOSE:To stably operate an ozonizer while preventing release of coating film for a long period of time in the ozonizer wherein a coating film of metal sputtering is formed on the inner face of glass tube to make discharge tubes of high-voltage electrode by specifying thickness of coating film. CONSTITUTION:A coating film 11 of metal (e.g. coating film of stainless steel) is formed in 2,000-5,000Angstrom  thickness on the inner face of glass tube by sputtering technology to produce discharge tubes 10 of high-voltage electrode. Then the prepared discharge tubes 10 are placed in a stainless steel pipe 6 as an earth electrode while laying the opening of one electrode 10 against a flow of raw material gas and the end of the other electrode against the flow and continuous operation is carried out by using high frequency at >=600Hz wavenumber as an electric source to generate ozone. Consequently, the coating film 11 of metal having ozone resistance and nitric acid resistance is formed on the inner face of the discharge tubes 10, no problem will occur even if operation is done with laying the opening of the discharge tube 10 toward the side of ozonized gas and a large volume of ozone can be stably obtained for a long period of time.

Title: Variable displacement swash plate type compressor
Inventor: SANUKI MASAMI
IPC: F04B27/08
Filed: 1988-01-08
Abstract: PURPOSE:To cool a shaft seal device even when the decompression condition occurs in an operation chamber on the front side by providing a bypass passage for connecting an intake chamber to an intake passage. CONSTITUTION:A bypass passage 301 for connecting an intake chamber 114 to an intake passage 300 is provided in a cylinder-block 101. Because the pressure in the intake passage 300 is lower than that in the bypass passage 301 due to the flow of a refrigerant sucked from the intake passage 300 into a swash plate chamber 70, the flow of the refrigerant through a circulation path 302 exists even when the decompression condition occurs. The refrigerant continuously flows from the swash plate chamber 70 into the intake chamber 114 to cool a shaft seal device 107 mounted in the intake chamber 114, so that sezur does not occur in the shaft seal device 70.
