IPC: D21H13/44
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a mineral fiberboard having a low specific gravity while having a practical strength as an internal finishing material for building. SOLUTION: When an amphoteric ionic polyacrylamide-based flocculant having 0.5-1.0 ratio of the numbers of cationic and anionic functional groups and 2,000,000 to 3,000,000 molecular weight as a flocculant is added together with a binder and a filler to mineral fibers and dispersed in water, the mineral fibers are adsorbed with functional groups having positive ions of the polyacrylamide-based flocculant at the time of producing a mineral fiberboard according to a conventional method by a wet sheet forming method. On the other hand, the functional groups having negative ions are adsorbed through an additive having positive ions on the mineral fibers to retain the strength of the resultant mineral fiberboard. Furthermore, the formation of flocs in water is moderately increased to afford the bulky mineral fiberboard having a low specific gravity.

Title: Gas laser oscillator
Inventor: MURATA TAKAAKI
IPC: H01S3/03
Filed: 1991-07-29
Abstract: PURPOSE:To increase collision of electrons in an electrode layer, to decrease a voltage of the layer, to reduce a loss in the layer, and to reduce a wasteful power loss which does not contribute to laser excitation by applying a magnetic field perpendicularly to a direction of an AC electric field to be applied between electrodes. CONSTITUTION:When an AC voltage is applied between discharge electrodes 4a and 4b by an AC power source 5, an AC discharge is generated through dielectric elements 3a, 3b, and gas is excited to generate a laser 8. In this case, a magnetic field is generated laterally to an electric field on a surface of the lower surface element 3a of the electrode 4a by permanent magnets 9a, 9b disposed near the electrode 4a. Further, a magnetic field is generated laterally to an electric field on the surface of the element 3b of the electrode 4b by permanent magnets 9c, 9d disposed near the electrode 4b. When a magnetic field is applied laterally to an electrode layer, collision of electrons is increased, and hence ionization is strengthened, and loss in the layer can be reduced.

Title: Delay circuit structure
Inventor: SATO NORIO
IPC: H01P9/02
Filed: 1988-07-29
Abstract: PURPOSE:To miniaturize the title delay circuit structure and to densify the structure by adhering two insulating substrates to each other so that respective ground patterns on the rears of the two insulating substrates can join with each other and mutually connecting the strip lines of both the two substrates through through holes provided for positions to avoid the ground patterns so as to penetrate both the two substrates. CONSTITUTION:Ground patterns 12 and 22 of substrates 10 and 20 are opposed to each other, further the substrates 10 and 20 are solder-joined and adhered to each other so that through holes 31 and 41 of both the substrates 10 and 20 can coincide with each other and unified, and at the same time, the through holes 31 and 41 are also joined with each other with internal solder 50. Since a longitudinal directional dimension l' of the second substrate 20 is smaller than a longitudinal directional dimension l of the first substrate 10 (l>l') here, the lower area of the first substrate 10 never overlaps with the second substrate 20. Consequently, two ground terminals 16 are linked to both the lower edges of the first substrate 10, which never overlaps with the second substrate 20, by caulking or soldering, etc. In the same manner, signal leads 14a and 14b are linked to conductor land parts 13 and 23 at the outer edges of spiral strip lines 11 and 21 of both the substrates 10 and 20 by caulking or soldering, etc. Thus, the structure can be miniaturized and densified.

Abstract: PURPOSE:To wash efficiently a gas by atomizing the spray liquid into extremely fine particles to increase the contact surface area between gas and liquid, and then separating surely gas from liquid. CONSTITUTION:A gas to be washed is sent into a gas and liquid mixing part 1 from an apparatus A through an introducing pipe 11, and washed by the atomized liquid spouted from a spray 17 while passing through passages 14, 15, and 16. The larger particles among the atomized liquid in the gas and liquid mixing part 1 are discharged to the outside of the apparatus from a liquid discharge port 18. Besides, the smaller liquid particles entering the gas flow are sucked into a centrifugal turboblower 22 in a compression part 2. The gas and liquid mixture from the blower 22 is spouted into the passage 35 of a cyclone 3. The gas separated from liquid is sucked into the lower compression part 4 through a passage 37, and again compressed by the operation of a centrifugal turboblower 41. Consequently, the remaining liquid particles are separated and removed, and the gas flows into the lower cyclone 5 and purified. The purified gas is sent into the apparatus A through a gas suction pipe A2.

Title: Trouble cause diagnostic device and its knowledge base preparing method
Inventor: KATO HIDEKAZU
IPC: G03G15/00
Filed: 1990-07-17
Abstract: PURPOSE:To shorten the joining time of an expert and to improve the productivity by defining a fact that the cause of a trouble was inferred based on the knowledge information stored in a knowledge base. CONSTITUTION:When the information that chooses a specific constitutional unit is inputted to a knowledge input part 2, a casual sequence chain tree production part 7 combines the structure knowledge stored in a knowledge memory store part 6 with the general knowledge to produce the trouble cause candidates and displays these candidates at a knowledge display part 4. An expert chooses these cause candidates and inputs the selected one to a knowledge editing part 3 to update the knowledge information stored in the part 6. In an expert system 1, the knowledge information stored in the part 6 is accordant with a actual trouble factor with repetition of the operations. Thus the part 7 combines the structure knowledge 8 stored in the part 6 with the general knowledge 9 to generate the information equivalent to the expert knowledge. Then the joining time of the expert can be shortened and the productivity is improved.

Title: Temperature and pressure measuring device in pressure-reduced atmosphere
Inventor: MATSUYA HISAMI
IPC: G01K1/14
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To precisely measure temperature and pressure in a pressure-reduced atmosphere by calculating the pressure from a preliminarily stored relation between saturated temperature and saturated steam pressure on the basis of the detected temperature of a temperature sensor having a thermosensitive part the circumference of which is filled with saturated steam. SOLUTION: A water absorbing member 4 sucks water from a vessel 1, and the thermosensitive part 3 of a temperature sensor 2 makes contact with both water and steam. Since the vessel 1 is set within a pressure reduced atmosphere, generation of steam from the level of the vessel 1 and the surface of the water absorbing member 4 is promoted, and the circumference of the thermosensitive part 3 is laid into the state filled with saturated steam. The temperature sensor 2 then detects the water temperature (steam temperature), and a pressure arithmetic means 5 calculates the pressure from a preliminarily stored relation between saturated temperature and saturated steam pressure on the basis of the detected temperature. The temperature and the pressure are displayed by a temperature display means 7 and a pressure display means 6.  Thus, the temperature and pressure in pressure-reduced atmosphere can be regularly measured with high precision.
