Title: Preparation of terephthalic acid aqueous slurry
Inventor: IZUMISAWA YOSHIAKI
IPC: C07C63/26
Filed: 1994-11-15
Abstract: PURPOSE: To prepare a teraphthalic acid aqueous slurry by crystallizing a terephthalic acid slurry obtained by oxidizing p-xylene in an acetic acid solvent, separating the crystals, washing the crystals with p-xylene, and subsequently mixing the crystals with water to replace the dispersion medium with water. CONSTITUTION: p-Xylene is oxidized with O2 in the presence of a catalyst in an acetic acid solvent in a liquid phase to obtain the acetic acid slurry of the terephthalic acid. The produced terephthalic acid crystals are separated from the slurry. The acetic acid-containing terephthalic acid crystals are washed with p-xylene, and subsequently mixed with water. Thus, the p-xylene solvent is replaced with water to obtain the terephthalic acid aqueous slurry. The p- xylene left in the aqueous slurry is removed by a phase separation method or by a heating evaporation method. At least a part of the washing solution containing the p-xylene is preferably recycled into the substance system. The p-xylene is preferably washed by a replacing washing method or by a slurry- washing method. Further, the terephthalic acid aqueous slurry is preferably pressed and heated to dissolve the terephthalic acid, and the produced aqueous solution is subsequently reduction-purified in the presence of a platinum group metal catalyst at a high pressure and at a high temperature.

Title: Noise reducing device
Inventor: YUYAMA MASAMI
IPC: H04N5/21
Filed: 1984-12-26
Abstract: PURPOSE:To reduce the noise in a video signal certainly and to prevent the deterioration in a picture quality by detecting the noise level of a synchronizing signal portion and controlling the volume of a noise attenuation or the level of the noise slice according to the noise level. CONSTITUTION:A sampling circuit 19 samples a video signal A by a timing pulse C and outputs a noise component D to a level detecting circuit 20 after taking out if from the synchronizing signal part. The level detecting circuit 20 outputs a DC voltage corresponding to the level to a voltage control amplifier (VCA) 16. The VCA 16 amplifies an inversion output I of the inversion circuit 15 according to the output signal of the level detecting circuit 20 and outputs the amplified output to a registration circuit 11. In this case, the larger the noise of the video signal A, the larger the output of the VCA16 and the smaller the noise of the video signal A, the smaller the output of the VCA16. And the signal outputted from the VCA16 and the video signal A from a videohead are composed at the registration circuit 11 and as a result, the noise component is cancelled.

IPC: H05K1/11
Filed: 1989-10-27
Abstract: PURPOSE:To minimize the resistance of a via hole and enhance the reliability of conduction by forming a via hole which interconnects a pair of lands by way of an insulation layer at a position deviated form the via hole which penetrates the insulation layer directly below. CONSTITUTION:To each conductor layer which has formed a multi layer by way of an insulation layer are formed the same-shaped lands 11, 12, and 13 so that they may be piled up. A first layer via hole 31, a second layer via hole 32, and a third layer via hole 33, which are all designed to connect a pair of lands 11 to 12, a pair of lands 12 to 13, and pair of lands 13 to 14, which face each other by way of an insulation layer, are formed at a position at least deviated from a via hole which penetrates an insulation layer directly below. Therefore, the depth of the prepared via hole is substantially identical to the thickness of the insulation layer or shallow. Therefore, metal can be attached satisfactorily on the inner wall and the bottom of the prepared hole for the via hole for any of plating means, and vapor deposition means. In other words, there is no danger that the resistance value of the via hole section will be increased, thereby eliminating the potentiality of conduction failure.

IPC: G11B33/02
Filed: 1985-12-13
Abstract: PURPOSE:To observe a cassette loaded through the transparent door of a cassette insertion opening by composing the door of the transparent door and an index door and holding the index door forcibly at an opening position when the cassette is inserted. CONSTITUTION:The 2nd opening/closing lid 5 where a specific index is drawn and the 1st transparent opening/closing lid 8 on it are supported rotatably on a rotating shaft 7 and they are closed in the insertion opening normally by a spring, so that the specific index is displayed. Driving arms 14 and 15 abut on the lids 5 and 8. When a cassette is inserted, the lids 5 and 8 rotate and a cam plate 13 is driven to rotate arms 14 and 15 as shown by an arrow. Then, the arm 14 falls in the small-diameter part of the cam at a specific position and while the lid 8 is closed, only the lid 5 is held open. Consequently, the loaded cassette is observed because the insertion opening consists of the transparent lid 8, and foreign matter is prevented from entering the inside.

Filed: 1986-11-27
Abstract: PURPOSE:To prevent the entrainment of powder and to obtain a cast slab having excellent surface characteristic by working static magnetic field generator at the initial stage till pouring steel in a mold reaches the position of discharging hole in a submerged nozzle and promoting the melting of powder on the molten steel surface in the mold. CONSTITUTION:After starting molten steel pouring into the mold 10 in continuous casting, at the time, which the pouring molten steel into the mold is reached the lower end part of the submerged nozzle 8 under closing the bottom part of mold by a dummy bar head and at latest, reached the position of the discharging hole 8A in submerged nozzle 8, the work of electromagnetic brake 16 is started. And, by dispersing the molten steel discharging flow from the discharging hole 8A in the submerged nozzle 8, the temp. of mold powder 12, which is not yet melted and is floated as covering molten metal surface, is risen to about 20 deg.C. Thus, the powder 12 is melted at early time, and the surface defect caused by entrainment of the powder developing on the drawing cast slab at initial stage is scarcely eliminated.
