Abstract: PURPOSE:To facilitate the granulation and obtain a granular agrochemical excellent in binding properties and underwater disintegrability and spreadability by adding a specific copolymer thereto. CONSTITUTION:This binder for an granular agrochemical and underwater disintegrability and spreadability imparter is obtained by adding about 0.2-10wt.% copolymer of (A) an alpha, beta-unsaturated carboxylic acid (salt) with (B) an acrylate or a methacrylate of a 15-50mol adduct of a 6-30C monool, (C) a hydrophobic unsaturated monomer and, as necessary, (D) other copolymerizable monomers. The amounts of the components in the copolymer are usually 20-90wt.% component (A), 5-60wt.% component (B), 5-50wt.% component (C) and O-30wt.% component (D). The weight-average molecular weight of the copolymer is 1000-500000. Water is added to a mixture of an agrochemical technical product with an inorganic mineral carrier to provide a pasty form and the granulation is then carried out with a granulator.

Title: Purification of xanthane gum
Inventor: MORIKAWA MITSUO
IPC: A23B7/12
Filed: 1988-08-26
Abstract: PURPOSE:To accomplish the purification of xanthane gum improved in the clearness of its aqueous solution without impairing its characteristics by holding a crude aqueous solution of xanthane gum at a specified temperature to flocculate the impurities contained followed by cooling the system to a specified temperature, filtration and the dehydration to make a recovery. CONSTITUTION:A crude aqueous solution of xanthane gum produced by e.g., a culture method is warmed for 0.5min-3hr to 80-90 deg.C and kept in this state to effect flocculation of the impurities protein contained in the solution without causing viscosity drip-off due to thermal deterioration. Thence, the temperature of this solution is lowered to 55-65 deg.C, and the system is subjected to filtration to remove the insolubles such as protein flocculated. KCl is added to the resultant filtrate followed by adding 2-3vol. times the filtrate volume of a hot water- soluble solvent such as isopropyl alcohol to the system to separate a xanthane gum precipitate out. This precipitate is then squeezed, dried and ground, thus obtaining a purified product. Thereby the objective purified xanthane gum can be obtained. This purified xanthane gum is such that its aqueous solution is favirable in clearness with the viscosity also favorably, retained.

Title: High pressure sodium lamp
Inventor: OGATA YOSHIROU
IPC: H01J61/35
Filed: 1982-12-02
Abstract: PURPOSE:To enable a high pressure sodium lamp to be restarted in a short time and achieve a constant lighting state in a short time by forming an infrared reflecting film on the surface of an outer tube in which an emission tube is installed, and charging the outer tube with an inactive gas. CONSTITUTION:An emission tube 1 is incorporated in the center of an outer quartz tube 8. An infrared reflecting film 9 containing a titania-silica multiple interference film having a transmittance of over 95% in the visible range and a mean infrared reflectivity of over 75% in the wavelength range of 800-1,100nm, is formed over the outer surface of the outer tube 8. Besides in such a high pressure sodium lamp, the outer tube 8 is charged with argon gas 14. As a result, after the lighting of the lamp is suppressed, the lamp can be cooled rapidly due to the heat conducting effect of argon gas 14 and can be restarted within five seconds. In addition, after the lamp is restarted, spectrum radiated by sodium vapor contained in the emission tube 1 is efficiently reflected by the infrared reflecting film 9 enabling a constant lighting state to be achieved within 10-15sec.

Title: Endless conveyor belt
Inventor: TAKAMURA YOSHIYUKI
IPC: B65G15/42
Filed: 1986-09-09
Abstract: PURPOSE:To improve flexibility in an endless conveyor belt as well as to prevent moisture and dust from penetrating into an elastic body, by concealing both sides of the elastic body inside the storage space formed between both inner and outer circumferential flexible belts, with a bending part made up of bending both sides of the outer circumferential flexible belt inward. CONSTITUTION:In the state that both sides of an outer layer part 2 of an outer circumferential flexible belt 1 is bent inward and a bending part 3 is formed, this outer circumferential flexible belt 1 is sewed together with an inner circumferential flexible belt 4 with some puffs in parallel at regular intervals in the circumferential direction. With this operation, at intervals between each sewing part 5, a separate storage space 6 is formed between both these flexible belts 1 and 4. Sponge (an elastic body 1) is inserted into each storage space 6, the underside of sponge 11 is stuck to the inner circumferential flexible belt 4, and both sides 12 of this sponge 11 is concealed by a top part 9 of the bending part 3. Moisture and dust of an article being conveyed by the endless conveyor belt formed like this is not entered into the sponge 11 concealed by this bending part 3 and, what is more, no adhesive agent is used so that such a fear that flexibility inherent in the conveyor belt might be damaged is utterly nothing there.

Title: Coating film for detecting fuel gas leakage
Inventor: HASHIMOTO TSUTOMU
IPC: C09D7/12
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To change a color and stably detect the leakage of a gas at normal temperature to a temperature as high as about 500 deg.C by contact with the gas in relation to a coating film for detecting the leakage of a fuel gas. SOLUTION: This coating film for detecting the leakage of a fuel gas is capable of inserting an imitation tube 2 for the leakage of the fuel gas into a glass outer tube 1, coating the periphery with a coating film sample 5, hermetically sealing the interior of the glass outer tube 1 with flanges 6a, 6b, 7a and 7b, making a fuel imitation gas 14 flow through the interior, jetting the gas 14 from holes on the surface of the imitation tube 2 to the periphery, making air flow through the periphery, heating the tube with a spiral heater 3 from normal temperature to 500 deg.C, carrying out a test on detection of the gas leakage, thereby discoloring the coating film sample 5 and enabling the discrimination of the gas. A group 3A to 4B metal oxide powder of the 4th to the 6th period is used as a pigment in the coating film, which is stable to ultraviolet rays.  Since an alkoxysilane is used as a binder, the durability under high-temperature conditions is excellent and the detection of gas leakage with the stable discoloration can be performed even by applying the coating film to a boiler outer wall, etc., at a temperature within the range of normal temperature to 300 deg.C or 300 to 500 deg.C.

Title: Preventing system from setting number of copies for reproduction in copying machine
Inventor: YAMAGUCHI MORITOSHI
IPC: G03G15/00
Filed: 1983-11-14
Abstract: PURPOSE:To prevent setting of a copying sheet number during the detection of an abnormal state by detecting an abnormal state of a copying operation, and inhibiting the setting of a copying sheet number until its release is executed. CONSTITUTION:When an abnormal state of a copying operation such as a jam of copying paper, etc. is generated when copying is executed continuously, and it is detected by an abnormal state detecting circuit 1, an output signal of the abnormal state detecting circuit 1 is varied to ''0'' from ''1'', and the gate of an AND circuit 3 is closed, therefore, in this case, even if a ten key 2 is depressed, its signal is not supplied to a copying sheet number display controlling circuit 4. Accordingly, even if the ten key 2 is depressed by mistake in case when the abnormal state detecting circuit 1 detects the abnormal state, contents of a down-counter are not changed, and a copying sheet number display 5 displays the remaining copying sheet number. As a result, setting of the copying sheet number can be prevented.

At the time of correction in this state, a feed lever 5 is driven and the correction ribbon 4 rises to be moved to a correcting position. The feed gear 19 accurately fed by one correction character moves in the direction away from the take-up reel 24 along with a revolving lever 21 but the pawls 19a are in contact with the peripheral surface of the correction ribbon 4 under the tensile force of a spring 22. Therefore, the correction ribbon is alway taken up by one corrected character even if the winding diameter of the correction ribbon 4 increases and the wastefulness of the correction ribbon is not encountered.
