Title: Medium and device for recording and reproduction
Inventor: KUWAMOTO MAKOTO
IPC: G11B7/257
Filed: 1992-10-23
Abstract: PURPOSE:To repeatedly perform recording/reproducing with the same laser light and to enable recording/reproducing a piece of information smaller than a spot size by utilizing a surface plasmon resonance phenomena excited on a heating layer. CONSTITUTION:A heating layer 3 is arranged on the surface of a substrate 1 and a recording/reproducing layer 5 is provided on the heating layer. The reproducing layer 5 is composed of either a phase transition material or a magneto-optical film. This medium is recorded/reproduced by using the surface plasmon resonance. A prism 13 is arranged over the reproducing layer 5 separated by a slight gap and a P polarization wave having the frequency omega is made incident on a prism with an angle theta larger than a crytical angle as a recording/ reproducing light 15. When the angle theta becomes a certain specified angle, the surface plasmon resonance is excited and the reflectivity is decreased. The characteristic of reflectivity for the angle theta is changed between the recording part 19 of the recording reproducing layer 5 and the non-recording part. Consequently, by fixing the angle theta and scanning the medium surface, the reflected light quantity is changed and the reproducing signal is detected.

Title: Scroll compressor
Inventor: SAKAI MANABU
IPC: F04C18/02
Filed: 1989-11-02
Abstract: PURPOSE:To make stable operation possible by installing a spring member in a space between a back pressure partition band and a link-form groove formed in a bearing member housing the partition band so as to press this band against the back of a turning end plate at all times. CONSTITUTION:A refrigerant taken out of an inlet port 27 of a compressive mechanism 2 is successively compressed in a compression working space 12 and discharged out of a discharge port 28. At this time, axial thrust force is added to a turning end plate 11 from the space 12, therefore the back of this end plate 11 is made so as to be pressed against an axial supporting part 24 of a bearing member 18. However, a minute clearance 19 of the back of the end plate 11 is partitioned off by a back pressure partition band 21, and discharge pressure acts on the center side, while pressure in a proper intermediate part between discharge pressure and inlet pressure works on the outside so that axial thrust force out of the side of the space 12 is relieved, thus sliding loss at the support part 24 of the member 18 is abated. Even in the case where lubricating oil of pressure acting on the center of the back of the end plate 11 immediately after starting or operational conditions and so on does not flow into a groove 22 and the partition band 21 fails to operate, this partition band 21 is stably pressed by a spring member 23.

Title: Device for dewatering of strip
Inventor: YABUKI TAKASHI
IPC: B08B7/00
Filed: 1987-11-16
Abstract: PURPOSE:To perform dewatering by a noncontact device by installing a feed roller and a collection roller in the travel direction of a strip and a pair of coils between both the rollers to sandwich the strip, and supplying the same directional electric currents between the coils. CONSTITUTION:An electric current loop is composed of an power unit 9, feed roller 6, strip 1, and collection roller 7 and electric currents are supplied to the strip 1. Coils 8 are put between both the rollers 6, 7 and a magnetic field in the vertical direction is generated by supplying the same directional electric currents to the coils 8. At the time when the strip 1 enters the magnetic field, electromagnetic forces act in both the horizontal direction and the orthogonal direction to the travel direction of the strip 1 to remove lubrication oil remained on the strip 1. Hence, transfer of the strip 1 is facilitated because water remaining on strip edge parts is removed and also a force to move the strip 1 in the width direction is canceled.
