Title: Production of melamine resin
Inventor: YOSHIMITSU TOKIO
IPC: C08G12/34
Filed: 1982-04-15
Abstract: PURPOSE:To permit the viscosity reduction, pot life prolongation and water solubilization of a resin syrup and to produce a resin capable of providing decorative sheets having enduring water resistance and stain resistance, by adding a specified group-containing polyalcohol and an amide to a melamine resin. CONSTITUTION:Melamine is reacted with an aldehyde (e.g., formaldehyde). After adding a 4C or higher polyhydric alcohol containing one imino or amino group in the molecule (e.g., diisopropanolamine, monoaminobutylene glycol) and an amide (e.g., p-toluenesulfonamide, xylenesulfonamide), the reaction mixture is further reacted. Thus the viscosity reduction, pot life prolongation and water solubilization of a melamine resin syrup become possible in plasticizing a melamine resin, and at the same time, a melamine resin which can provide decorative sheets having enduring water resistance and stain resistance can be obtained.

Abstract: PURPOSE:To make it possible to judge the conditions of a converter exactly, by producing a sound, having a frequency zone different from that of the sound of blowing now in operation and that of environmental noise, at a prescribed position in the furnace, and by detecting the change in the sound strength caused by the propagation of the sound in the furnace. CONSTITUTION:An AC signal, which is produced by a sine wave generator 40 of a top-blown converter and which has constant amplitude and frequency of a frequency zone different from that of blowing sound and from that of the environmental noise, is amplified by an amplifier 42. Then the voice coil 44a of a speaker 44 is energized, and the AC signal is converted to a sound signal by a diaphragm 44c. The sound signal is sent to a prescribed position above very near the molten steel surface by a transmission tube 46 of the sound wave. The transmitted sound is collected through slag 12, a wave guide 20 by a microphone 22, then after passing through a one-third octave analyzer 26, it is converted to DC by a AC-DC change-over switch 28. The DC is recorded by a recorder 30, whereby the change in the strength of sound wave during blowing is detected.

IPC: H04L1/00
Filed: 1995-03-23
Abstract: PURPOSE: To select a proper system by a reception side by performing decoding by plural error correction ratios or error correction systems and judging data from which no error is detected as the one decoded by a correct decoding system. CONSTITUTION: Reception data obtained via a transmitter/receiver 3 and a data reception part 41 is decoded by plural error correction decoders 51-53 in accordance with the plural coding systems or coding ratios at every reception frame. Error correcting parts 54-56 detect the error for respective coding system or coding ratio. A reception information decision part 57 judges the data from which no error is detected as a correct reception result, and sends a reception frame to which decoding is applied correctly to a control information readout part 44. In such a case, coding ratio designation information, etc., is read out, and it is sent to a coding control 38. Decided coding ratio information is assembled in transmission data, and returned to a transmission opponent.  In this way, the coding system or coding ratio is changed corresponding to the state change of a transmission line without deteriorating transmission efficiency.

Title: Optical recording medium
Inventor: KOBAYASHI TADASHI
IPC: G11B7/243
Filed: 1986-03-24
Abstract: PURPOSE:To maintain a recording state stable for a long period of time and to improve reliability by using an atomic radius effect compd. having an m.p. within a prescribed temp. range to form a thin film on which information is recorded. CONSTITUTION:An optical recording medium 1 is formed to a disk shape by laminating a substrate 3, a protective film 5, a recording film 7, a protective film 9 and a film 11 of a UV-curing resin in this order. The film 7 is formed on the film 5 by selecting the material from atomic radius effect compds. such as AuPb2 having 300-800 deg.C m.p. and forming the film by a sputtering method, etc. The atomic radius effect compd. having the m.p. ranging 300-800 deg.C permits phase non-averaging by melting and quick cooling by the irradiation of a light beam and since the phase averaging temp. is above a room temp., the recording pits subjected to the phase non-averaging exist stably at the room temp. The stable recording state is thus maintained without erasing of the recording information by the deterioration with lapse of time, thereby reliability is improved.

Title: Falseness-discernible printed matter
Inventor: KANEKO EISHIN
IPC: B41M3/14
Filed: 1990-03-16
Abstract: PURPOSE:To obtain a falseness-discernible printed matter for which a printing plate can be easily prepared and to which a latent image is given using low-cost offset printing technique by printing printed matter monochromatically with one and other sides of a pattern printed using an ink with varying gloss and thereby making the printed matter appear as if it were printed in a single type of ink if viewed in front and allowing a latent image to appear, if the printed matter is tilted. CONSTITUTION:This printed matter is printed in two different inks but appears as if it were printed monochromatically. In addition, it shows a latent image, if viewed from above and the latent image can be confirmed by tilting the printed matter. A glossy ink and a non-glossy ink of the same color are used, and these inks are used for offset printing, one over the other. The glossy ink-applied surface of the printed matter reflects regularly, while the non-glossy ink-applied surface reflects irregularly. Therefore, the value of aberration due to reflection irregularity allows the appearance of a latent image. The glossy ink uses a fine, sufficiently wettable organic pigment. The glossy ink is prepared by blending the pigment with a large amount of varnish. On the other hand, the non-glossy ink is mainly composed of an insufficiently wettable inorganic pigment with a large particle diameter, and a small amount of varnish kneaded with the former.

Abstract: PURPOSE:To prevent destruction of IC due to input uncertainty at input terminal open state by connecting an input terminal of a 1st logic confirming circuit to an input terminal of a logic circuit using a C-MOS and connecting the output terminal to the input terminal of a 2nd logic confirming circuit. CONSTITUTION:In applying logic 0 to the input terminal 1, the potential of the input terminal of the 1st logic confirming circuit 20-1 and the potential of the output terminal 24 of the a 2nd logic confirming circuit 20-2 go to 0. In this case, the potential of the input terminal 23 of the 2nd logic confirming circuit 20-2 is still 0 and the P-MOS 7 is turned on. Thus, a fine current flows through a resistor 10 and the P-MOS 7, but the potential at an output terminal 24 of the 2nd logic confirming circuit 20-2 is held to 0 by the resistor 10. During that time, the P-MOS 5 is turned on and the N-MOS 6 is turned off and the output terminal 22 of the 1st logic confirming circuit 20-1 goes to 1, that is, the input terminal 23 of the 2nd logic confirming circuit 20-2 goes to 1, then the P-MOS 7 is turned off and the N-MOS 8 is turned on. As a result, the potential at the output terminal 24 is made stable at a 0 level.

Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To rapidly decompose CMPO (octyl(phenyl)-N,N- diisocutylcarbamoilmethylphsophine oxide) safely, surely and by a mild condition. SOLUTION: The CMPO-containing matter is emulsified in an electrolyte containing an oxidation accelerating agent (silver ion) by an emulsifying machine of an emulsifying tank 6, and the electrolyte is fed to an anode chamber, and an electrolytic oxidation reaction is executed by energizing. An electrolysis is accelerated since a surface area of the CMPO containing with the electrolyte is enlarged by emulsifying the CMPO-containing matter. Since a sufficient CMPO decomposition is not attained by passing only once the electrolyte through an electrolytic cell, a batch type oxidizing method is adopted, and the anode liq. is circulated between the anode chamber, a thermostatic bath 7a and the emulsifying tank 6 by using a circulating pump 3a, and the electrolysis is continued in a state in which the CMPO-containing matter is always emulsified in the electrolyte.  The cathode liq. is circuilaed between a cathode chamber and the thermostatic bath 7b by using the circulating pump 3b. And in the anode 4 and the cathode 5 is the electrical cell 1, a supplied current is controlled by a rectifier 8.
