Title: Formation of ultrafine particle of oxide
Inventor: FUCHIDA HIDETSUGU
IPC: C01B13/20
Filed: 1986-09-29
Abstract: PURPOSE:In producing ultrafine particles of metallic oxide by heating and evaporating a metallic material in an oxygen-containing atmosphere by arc discharge between electrodes, to obtain high-purity ultrafine particles of metallic oxide, by constituting at least the cathode of carbon. CONSTITUTION:An anode 2 and a cathode 3 consisting of carbon are arranged in a vacuum container 1 and a metallic material a (e.g. Ru or Al) is put on the top of the anode 2. Then the vacuum container 1 is evacuated by a vacuum pump 9, an oxygen-containing gas is introduced through a feed pipe 5 into the container and the container 1 is filled with an oxygen-containing atmosphere. Then DC voltage is impressed to the anode 2 and the cathode 3, arc discharge is generated, the metallic material a is heated, evaporated and brought into contact with the oxygen-containing atmosphere to form ultrafine particles of metallic oxide. Consequently, since the cathode consists of a carbon electrode, the ultrafine particles of metallic oxide are not admixed with oxides of cathode like the case of tungsten cathode.

Title: High resolving power x ray tomographic imaging apparatus
Inventor: HIRANO TATSUMI
IPC: A61B6/03
Filed: 1987-09-14
Abstract: PURPOSE:To measure a plurality of tomographic images with the optimum resolving power at every size of an object to be examined, by mounting an X-ray detector having function capable of changing position resolving power to the size of the object to be examined. CONSTITUTION:The X-rays emitted from a synchrotron emitting light source 16 pass through a slit 17 to be brought to monochromatic X-rays having an arbitrary wavelength and high parallelization by a spectroscope 18. X-rays (two-dimensional projection image) after transmitted through an object to be examined are detected by an X-ray imaging tube 3 to be taken in a computer 10 through an X-ray imaging tube control apparatus 8 and a sequencer 9 and subsequently passed through a mechanism 7 for supporting and rotating the object to be examined from the computer 10 to rotate the object to be examined at an equal angle interval to again detect the two-dimensional projection image of the object to be examined. This operation is repeated until the angle of rotation of the object to be examined becomes 180 deg. or 360 deg.. From the obtained two-dimensional projection image group, image reconstituting operational processing is performed at every XY plane and a plurality of tomographic images are displayed on an image display apparatus 11. As mentioned above, since two-dimensional projection image measurement can be performed within one exposure time by the X-ray imaging tube, a plurality of tomographic images due to X-rays can be obtained within a short time.

Title: Optical disk device
Inventor: FUTAGAWA MASAYASU
IPC: G11B7/09
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent the problem in the constitution of a device such as miniaturization, the increase in power consumption and the decrease in the life of a light source since the movable range of an objective lens is required to be designed larger by the falling amount in order to prevent the objective lens from falling by gravity in the tracking direction. SOLUTION: A gravity sensor 19 for perceiving gravity in the tracking direction 35 is provided in an optical disk device and an offset current is made to flow through a tracking coil so that a thrust so as to cancel the perceived gravity is generated in an objective lens driving device 14. Since the fall by gravity of the objective lens 1 is reduced and it is not necessary to incorporate the portion of falling by gravity into the movable range of the objective lens at the time of designing the objective lens driving device 14, the movable range of the objective lens is reduced and thus, the diameter of an incident beam on the objective lens is miniaturized. Consequently, the miniaturization of the device, the reduction of a necessary light emitting amount, etc. are realized.

Title: Ventilation device
Inventor: IKEDA KAZUTOSHI
IPC: B60H1/24
Filed: 1990-08-29
Abstract: PURPOSE:To prevent contaminated outside air from flowing backward from an internal air discharge outlet into a room by providing a frame structure including electromagnet means on a valve seat part thereof, and a one-way valve including permanent magnet means mutually magnetically attracting the electromagnet means at a constant part between the valve seat part and it. CONSTITUTION:A one-way valve 4 is mounted on the surface of a frame structure 2 outside a room, and is closed, securely sealing an internal air discharge outlet 24 by the aid of contact force acting on the valve seat part 20 by self weight thereof and of magnetic attraction force of a permanent magnet member 5 to an electromagnet member 3 excepting the time when internal air R is discharged to the outside C of the room. Accordingly, the internal air discharge outlet 24 is not opened because of the valve 4 springing up owing to vibration produced upon an automobile running, and hence contaminated outside air is prevented from flowing backward from the internal air discharge outlet 24 into the room 13. When a sensor 73 of a control circuit 7 does not sense any contamination in the outside air, a current flowing through a coil 32 of the electromagnet member 3 is shut off and demagnetized. As the pressure difference between the inside B and outside C of the room exceeds the self weight of the valve 4, the valve 4 is separated off from the valve seat part 20 to discharge the internal air R to the outside C of the room.
