Title: Filter
Inventor: MATSUO HIDEYASU
IPC: B01D39/20
Filed: 1988-01-14
Abstract: PURPOSE:To provide a filter having an excellent durability, wherein collected dusts do not aggregate in filtering gases, by providing a SiO2 film with a thickness of 500Angstrom -50mum over most of the entire surface of a SiC particle excluding that of grain boundary portion. CONSTITUTION:The SiC particles constituting a filter form a matrix. Over most of the entire surfaces of the SiC particles excluding those of grain boundaries, films of SiO2 having a thickness of 500Angstrom -50mum are provided. When the thickness of the SiO2 film is smaller than 500Angstrom , the film loses the effect to trap the impurities moving from the SiC particles, whereas when the thickness is larger than 500mum, SiO2 films tends to separate from SiC particles due to the difference in thermal expansion. The SiC filter is obtained in the manner that all SiC particles throughout from the outer circumferential periphery to the inner periphery of the sinter of SiC are heat-treated in an oxidizing atmosphere, adjusting the period of the heat treatment.

Title: Dc power cable
Inventor: TAKAHASHI SUSUMU
IPC: H01B3/44
Filed: 1988-01-13
Abstract: PURPOSE:To enhance breakdown voltage by utilizing, as an insulator, an ethylene-acryl acid copolymer of a specific composition to suppress space charge from accumulating due to impression of high DC voltage. CONSTITUTION:As an insulator of a DC power cable, ethylene-acryl acid copolymer containing 0.5wt.%-10wt.% acryl acid is used. If the acryl acid content is less than 0.5wt.%, its effect on space charge leak is slight, and if it is 10wt.% and more, it lowers insulating resistance. After mixing and kneading given amounts of an oxidation inhibitor and crosslinking agent with the ethylene-acryl acid copolymer, the yield is subjected to thermopressforming to produce a crosslinking insulator. By crosslinking the insulator, its thermal deformation under high temperature is prevented. Moreover, maintaining the acryl acid content within the above range makes it possible to suppress accumulation of space charge due to impression of high DC voltage, and to enhance breakdown voltage of the DC power cable.
