Title: Water absorbing device from oil in equipment and submarine machine
Inventor: WASHIDA AKIRA
IPC: B01D17/04
Filed: 1979-03-22
Abstract: PURPOSE: To safely operate a submarine machine having a water absorber built-in oil room between motor chamber and machinery chamber by a method wherein conductive wire is installed within the absorber, and water absorption ratio of the body is detected by conductivity.  
     CONSTITUTION: Within the submarine machine 1, a motor chamber 12, an oil chamber 15, and a machinery chamber 3 are connected; the motor in the chamber 12 and a impeller 6 in the chamber 3 are connected with a shaft 11 via shaft-sealing supporters 18, 19; and the oil chamber 15 contains absorber 20 consisting of cellulose assembly. Two wires 22, 22 are installed within the absorber 20, and guided outside the submarine machine 1 via lid 21 installed outside the casing 4 of the machinery chamber 3. Water permeating the machinery chamber 3 is normally absorbed by the absorber 20 in the oil chamber 15 and is prevented from reaching the motor chamber 12. To ensure safety, water absorption ratio of the absorber 20 is detected by measuring conductivity across the wires 22 in the absorber 20.

Title: Agent which is corrosion-resistant and inhibits lowering of boiling point
Inventor: KATOU IKUHEI
IPC: C10N30/12
Filed: 1980-03-19
Abstract: PURPOSE: To provide an agent for inhibiting the lowering of a boiling point, which exhibits corrison resistance to metals, inhibits the lowering of a boiling point caused by water absorption, and is useful for inhibiting a lowering in performance of a lubricating oil, containing a compd. having an amino group and hydroxyl group in the molecule and a boron compd.  
     CONSTITUTION: There is provided an agent for inhibiting the lowering of boiling point, containing, as active components, a compd. having an amino group and hydroxyl group in the molecule and a boron compd. obtd. by dehydration-condensing boric acid with heating. It is presumed that said boron compd. has a strong hydration power, water is dissolved therein in a state in which water is difficultly evaporable, and thus, the boiling point of the dissolved water rises remarkably. As a result, water does not boil even when the temp. is not lower tnan the boiling point of water, and hence the boiling point of a base oil is difficultly lowered. An example of the compd. having an amino group and hydroxyl group in the molecule is a lower alkanolamine.

Title: Magnetooptical recording polarization optical system
Inventor: TANIGUCHI TADASHI
IPC: G11B7/135
Filed: 1992-01-24
Abstract: PURPOSE:To provide the magnetooptical recording polarization optical system capable of producing a small size and thin type magnetooptical recording pickup. CONSTITUTION:When light 28 is made incident upon a polarization film 15, where p-polarized light is transmitted to be made incident upon a photodiode 13, while s-polarized light is reflected to be made incident upon a 1/4 wavelength plate 17. This s-polarized light is reflected by a total reflection film 18 and is reciprocated in the 1/4 wavelength plate 17 to become the p-polarized light, which is, therefore, transmitted through the polarization film 15 to be made incident upon a photodiode 14. Consequently, when the light 28 inclined by 45 deg. in the polarizing direction to an incident surface of the polarization film 15 is used, a component of a polarization plane which is not rotated by a magnetooptical disk 29 is equally divided into the photodiodes 13 and 14. Consequently, the magnetooptical recording pickup can be produced, and moreover, this can be small-sized and thin structive.

Title: Two-dimensional flow velocity measuring instrument
Inventor: HAMANO YASUNORI
IPC: G01P5/20
Filed: 1995-01-31
Abstract: PURPOSE: To provide a two-dimensional flow velocity measuring instrument which can measure the flow velocity of a particle group with high accuracy and high contrast by easily discriminating the particle group even when strong visible background light exists in the measurement area. CONSTITUTION: Particles P are put in the flow F of the flame of a burner B and the particle group 16 is visualized by irradiating the particle group 16 with a sheet-like ultraviolet pulsed laser light 11 from an optical system 11. A camera 18 takes the picture of the visualized particle group 16 continuously or at very short time intervals and a computer 20 calculates the flow velocity vector of the group 16 by analyzing the positional variation of the group 16. Even when the flame itself exists as a visible light emitting source in the measurement area, the flow velocity of the group 16 can be found, because only the high-contrast picture of the group 16 can be obtained by irradiating the group 16 with the ultraviolet laser light and discriminating the group 16 through an ultraviolet-ray transmitting filter 19.  Therefore, the flow velocity of the particle group 16 can be measured with high accuracy by minimizing the influence of the background light as much as possible, because a high-contrast picture can be obtained from the group 16 even when the group 16 is not irradiated with high-power laser light.

Title: Multidirectional laser light sending-back device
Inventor: NAKAMURA TAICHI
IPC: H01S3/00
Filed: 1988-02-17
Abstract: PURPOSE:To continuously send back laser light within an angle range required for tracking by fitting reflectors as an assembly atop of an arm by installing it at one place on a spacecraft without limiting a visual field. CONSTITUTION:The reflector assembly 20 consists of four reflectors 13-16 and is fitted atop of the arm 18 so as to evade the limitation of the visual field by the aircraft. Here, the optical path l1 to one reflector is almost aligned with the optical path l2 of other reflectors, so the irradiation angles theta1 and theta2 of a chaser 11 are nearly equal. The sending-back angle of one reflector reaches its upper limit and when an object of irradiation is switched to a next reflector, the irradiation direction need not be set again. Consequently, the irradiation angle need not be set again on a laser irradiation side and the laser light is sent back continuously within the angle range required for tracking.

Inventor: AKAMATSU TAKESHI
IPC: C03B37/00
Filed: 1978-03-25
Abstract: PURPOSE: Optical fibers are passed through a vessel containing a liquid of a synthetic resin and another liquid with lower viscosity than the synthetic resin which  covers the surface of the resin from the top, thus forming the layer of covering the  optical fibers free from voids at a rapid speed.  
     CONSTITUTION: The coating layer on optical fibers is formed using applicator 8 in which liquid layer with lower viscosity 18 is provided on the surface of liquid silicone resin 6. Thus, the direct contact of the surface of the resin layer 6 with air is avoided and bubbles 7 accompanied by optical fibers 3 are taken out by making them rapidly ascending from liquid layer 18. The mixing of bubbles 7 into resin layer 6 is completely avoided, thus the void formation on the coating layer of the synthetic resin is prevented. The conventional techniques limitted the taking-up speed to 20 m/min; however, the present invention raised the speed to 100 m/min with high quality.
