Title: Magnetic bearing type turbo-molecular pump
Inventor: OZAKI JUNICHIRO
IPC: F04D19/04
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic bearing type turbo-molecular pump capable of reducing the following rotation of an inner ring of a protective bearing consequent to the rise of back pressure. SOLUTION: This magnetic bearing type turbo-molecular pump having protective bearings 27, 28 for supporting a rotor 1 in an emergency when normal support is not performed by magnetic bearings 24A-23C, is provided with a thread groove 61 with exhaust action from the protective bearing 27 side to the exhaust port 4 side. Gas pressure at the protective bearing 27 part is thereby lowered in comparison to a conventional constitution, and following rotation of an inner ring of the protective bearing 27 caused by the viscosity of gas is restrained. As a result, the available intake port pressure of the pump can be set higher.

In this case, the particles of platinum-group metal such as ruthenium, palladium, platinum, rhodium, iridium, osmium or the like is used as the metallic particles. The transparent conductive film containing 10 wt.% or more of the platinum metal is formed on the screen with the application of a coating, containing at least the platinum- group metallic particles having an average particle diameter of 50 nm or less. Inclusion of silica particles enhances the film strength. Lamination of one or more transparent conductive films, each having a different refractive index can yield low reflection.

Title: Device for dispensing liquid substance
Inventor: KURAUDEIO SOGURIANI
IPC: B67C3/26
Filed: 1990-07-06
Abstract: PURPOSE: To distribute a liquid substance without generating bubbles to enable separation of the bubbles by providing a deflector element having the middle part and forming a gap passing the liquid substance between the middle part and the inside face of a chamber, and making the width of the gap equal to the distance. CONSTITUTION: The middle part of a deflector element 22 abuts on the inside face of a chamber 20 and that is, the inside face of the chamber 20 is positioned at the side of the middle part with a nearly constant distance and a gap to pass the treating liquid is provided between the middle part and the inside face. The width is equal to the distance. During use, the liquid in a tank 7 flows through a duct 6 to the chamber 19 to always fill the chamber 19 with the liquid. The chamber 20 receives also the liquid through the hole 25 of a wall 17 and the hole 26 of a sleeve 21 to fill it with the liquid. The liquid which reaches the chamber 20 through the hole 25 before the liquid reaches a hole 13 flows along passages shown in arrow marks F in a nearly laminar motion and hits the deflector element 22.  Since the liquid brought into contact with the deflector element 22 moves in a laminar flow, generation of bubbles is prevented while the liquid passes through the lower chamber 20 and further the bubbles in the liquid in the upper chamber 19 are also removed.

Title: Superconductor quantum interference element
Inventor: OOKAWA KUNIO
IPC: G01R33/035
Filed: 1988-07-16
Abstract: PURPOSE:To enhance measuring accuracy by distorting a magnetic field to be measured by mounting a superconductor ring containing two Josephson elements and the wiring formed from a non-magnetic normally conductive substance connected to said superconductor ring. CONSTITUTION:A part of the second insulating layer 12 covering a main coil 3 is contracted to expose a part of the coil 3 and wiring 19 is connected to the coil 3. The whole of elements is immersed, for example, in liquid helium along with a substrate 2 to be cooled and a part formed of a superconductive material is transferred to a superconductive state. The magnitude of a superconductor current made possible to flow to a superconductor ring consisting of the coil 3, an upper electrode 5, a connection layer 11 and a connection electrode 22 as is convensional without generating potential becomes a function of interlinking magnetic flux and changes in a cycle of a magnetic flux quantism phi0. Corresponding to this, an I-V characteristic also changes in the cycle of the quantum phi0. The magnetic flux density in the vicinity of the coil 3, for example, when a uniform magnetic field (a) to be measured is incident to a diagonally downward direction from an X-axis direction can be accurately measured without distorting the magnetic field even when the elements are placed in the magnetic field to be measured, because wirings 18, 19 are formed from a non- conductive material.

Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To realize the rapid drying of ink without deteriorating the penetrability of the ink into a recording sheet by applying a resin having an anionic group and a cationic group to the recording sheet or impregnating the sheet with the resin. SOLUTION: A resin having an anionic group and a cationic group is applied to a recording sheet or the sheet is impregnated with the resin so that an aqueous ink rapidly penetrates the recording sheet to expedite the drying of the ink without causing an ink run called 'bleeding' or 'feathering' in the recording sheet, when printing is performed using the ink. A coloring material is fixed in the recording sheet to inhibit an ink run by making the cationic group or the anionic group of the coloring material react chemically with the anionic group or the cationic group of the resin which is applied to the recording sheet or with which the recording sheet is impregnated and thereby binding the groups together, when the ink using the coloring material having the cationic group or the anionic group, is supplied to the surface of the recording sheet.

IPC: H05K7/12
Filed: 1989-07-11
Abstract: PURPOSE:To fix electric apparatuses on a rail without having a play between each apparatus and the rail and allow the electric apparatuses to be installed by itself to a wall surface or to be installed after arranging them numerously by disposing a member which is equipped with each elastic protrusion protruding to the direction lower than a base in an unrestricted state at both sides of the base of the electric apparatus and is used for preventing each apparatus from shifting sideways. CONSTITUTION:When an electric apparatus 2 is installed to a general-purpose rail 1 for parallel installation, the pointed end face 95 of each elastic arm 94 of a plate 9 for preventing the apparatus from shifting sideways faces an upper face of each edge 11 of the rail 1. In such a case, a fixed claw 4 is hooked in the direction of an arrow A and after that, is pressed in the direction of an arrow B. Then, a movable claw 5 advances or retreats in the direction of an arrow C and both edges 11 of the rail 1 are held down and are sandwiched by fixed and movable claws 4 and 5. Further, each elastic arm 94 of the plate 9 for preventing the apparatus from shifting sideways is displaced elastically in the direction of an arrow E and its arm reaches the upper face of the edge 11 of the rail 1. The arrival of the elastic arms 94 to the upper faces of edges 11 of the rail 1 allows the electric apparatus 2 to be installed and fixed furthermore strongly without having a play between its apparatus 2 and the rail 1.

Title: Attenuation equalizer
Inventor: UCHIDA TAKASHI
IPC: H03H7/01
Filed: 1993-06-28
Abstract: PURPOSE:To exclude the difficulty of adjustment for providing desired characteristics and to miniaturize the device by serially connecting a variable capacitor and a dielectric resonator between the resistor of the parallel arm of a bridging T-shaped resistance attenuator and the ground. CONSTITUTION:Between a resistor Rb of the parallel arm of the bridging T-shaped resistance attenuator and the ground, a variable capacitor C and a dielectric resonator 1 are serially connected. A resonance frequency fr of the dielectric resonator 1 is almost matched with a central frequency fo of a BPF (band pass filter) defined as a correction target. Then, the electrostatic capacity of the variable capacitor C is changed. Thus, the sharpness cattenuation inclination) of a transmission characteristic (attenuation characteristic) (a) is adjusted so as to provide the desired characteristic by moving an anti-resonance frequency fa while changing the capacity ratio of the dielectric resonator 1 with braking capacity Co. In this case, a return loss is degraded rather than the conventional value by omitting a serial resonance circuit provided parallelly to a conventional serial arm but this value can be compensated by before and behind circuits to be mounted and does not become any problem for practical use.
