IPC: C01B21/04
Filed: 1989-03-24
Abstract: PURPOSE:To contrive the recovery of a difficultly adsorbable gas with a good degree of efficiency by providing a porous resistance plate perpendicularly to a gaseous stream on an adsorbent bed of an adsorptive separating tower filled with adsorbent. CONSTITUTION:A mixed gas (e.g. air) is separated into a difficultly adsorbable gas (e.g. oxygen) and an easily adsorbable gas (e.g. nitrogen) by pressure swing process using an adsorbent (e.g. zeolite) for effecting a selective adsorption of the gas of a specific component. A porous resistance plate 13 is provided perpendicularly to a gaseous stream on an adsorbent bed 11 of an disruptive separating tower 10 filled with the adsorbent. This reduces the amount of the easily adsorbable gas being carried off with the difficultly adsorbable gas in the process of recovering the difficultly adsorbable gas, which, therefore, can be efficiently recovered as a whole.

Title: Leakage sensor for low conductivity liquid
Inventor: KOBORI TAMOTSU
IPC: G01N27/04
Filed: 1995-03-29
Abstract: PURPOSE: To provide a leakage sensor for low conductivity liquid, e.g. isopropyl alcohol. CONSTITUTION: Two electrode wires 1a, 1b employ braided insulation 2a, 2b allowing the passage of liquid and one more electrode wire 1c employs plastic insulation 2c. Three electrode wires are then stranded and applied with a braided protective layer passing liquid thus forming a leakage sensor 4a. The braided insulators 2a, 2b are impregnated with a surfactant, e.g. alkylamine salt. When a leaked liquid intrudes into the sensor, the surfactant is dissolved and ionized. Consequently, even a low conductivity liquid produces an electrolytic solution which causes short circuit of the electrode wires 1a, 1b. Leakage can be detected based on the variation in the electric resistance. The electrode wire 1c is used, in conjunction with a known means, for locating the leakage and detecting disconnection.

Filed: 1985-04-04
Abstract: PURPOSE:To easily clean a photosensitive body for a long period by making one of two thickness-directional layers of a cleaning blade smaller in hardness than the other and using the low-hardness layer for the side of a photosensitive body. CONSTITUTION:The cleaning blade 1a is formed of two layers in its thickness direction; one layer 3 is formed of a material having smaller hardness than the other and the other layer 4 is formed of a material with larger hardness. Then, the layer 3 is used for the side of the photosensitive body 2 to remove toner from the surface of a photosensitive drum by the layer 3, so that the photosensitive body 2 is never damaged. The layer 4 adjoining to the layer 3 backs up the layer 3 and prevented the wear of the photosensitive body 2 from being accelerated. Consequently, the blade 1a neither curves nor deforms permanently and is pressed against the photosensitive body 2 with constant pressure, thereby cleaning the photosensitive body easily for a long period.

Filed: 1984-04-12
Abstract: PURPOSE:To provide a sealing device which is thin and has a longer service life by making one of magnetic pieces thinner than the other and filling magnetic fluid into the clearance of either the magnetic pieces or magnets. CONSTITUTION:A magnetic piece 3 is made thinner than a magnetic piece 4, and the inner diameter of the magnetic piece 3 is made larger than the inner diameter of the magnetic piece 4. Magnetic fluid 9 which has a suitable viscosity and respond to the magnetic flux density is filled and retained in the smallest clearance (c) formed between the surface of a shaft 1 and the inner circumferential surface of the magnetic piece 4. As the magnetic fluid 9 is filled only in the clearance (c), the heat dissipation capability is substantially increased, and the vaporization of the magnetic fluid is prevented. As a result, the thickness of a sealing device can be made smaller.
