Filed: 1991-07-17
Abstract: A noncontacting face seal has a stationary sealing ring (4) and a rotating sealing ring (3) with opposed radially extending sealing surfaces (3S,4S) for restricting a fluid flow from a high pressure fluid side (H) to a low pressure fluid side (L). The rotating sealing ring (3) is brought out of contact with the stationary sealing ring (4) under hydrostatic force from fluid. The noncontacting face seal comprises spiral grooves (33) formed in one of the sealing surfaces (3S,4S) and extending from a low pressure fluid side (L) to a high pressure fluid side (H) in a radial direction so as to pump fluid in the low pressure fluid side (L) towards the high pressure fluid side (H), and a spaced portion (31,38) formed in one of the sealing surfaces (3S,4S) and extending inwardly from one circumference of the sealing surface at the high pressure fluid side (H) so as to introduce fluid in the high pressure fluid side (H) between the sealing surfaces (3S,4S).

Abstract: A pigment, a production process therefor, a process for improving its weather resistance, and a metallic paint made therefrom. The pigment includes a transparent or semi-transparent scaly substrate (100), a TiO₂ layer (101) coated on an entire surface of the substrate, light absorbing portions (102) formed on a surface of the TiO₂ layer in a scattering manner and including low order oxides of titanium, and glossy portions (103) formed on a surface of the TiO₂ layer in a scattering manner and having a metallic glossy effect. The pigment produces a metallic glossy effect resulting from the glossy portions, strong interference colors resulting from the TiO₂ layer and substance colors resulting from the light absorbing portions, and it exhibits a great covering power. The pigment can be obtained by a sputtering process carried out onto a conventional pearl mica pigment, and its weather resistance can be improved by repeatedly coating chromium (III) hydroxide on a conventional pearl mica pigment before and after the sputtering. The metallic paint made using the pigment is suitable for an automobile top coat paint.

Inventor: AYANABA ABATENI
IPC: A01N63/20
Filed: 1991-12-18
Abstract: Biocontrol particles for treating plants infested with nematodes comprise granules consisting of spores of bacterial nematicides which are contained in a biodegradable gel matrix formulated for controlled spore release. The bacterial spores are obtained by growing bacteria in nematode hosts which are in turn infesting plant roots. The roots are comminuted and used to prepare either dried or fresh inocula, which are then encapsulated into gel beads. Included in the method is a heat-treatment which kills the nematodes while maintaining the viability of the bacterial spores. To kill or inhibit the reproduction of nematodes, the biocontrol granules are deposited near plants or sowed with seeds, after which spores are released gradually through the biodegradation of the gel matrix of the granules.
