Title: Controller for dc brushless motor
Inventor: AIBA KENICHI
IPC: H02P6/06
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To make restrictive a rise in the terminal voltage of a motor even though the rotating speed of a motor increases, by providing field weakening means for corresponding a phase with an overvoltage of the motor and also a phase current of the motor, so as to restrict a terminal voltage of the motor when the rotating speed of the motor becomes high. SOLUTION: A rotating speed ω and a speed command ω* obtained from a position signal ϕ by speed arithmetic means 45 are inputted to a comparator 46, and its error is inputted to a PI controller 41. An output from the PI controller 41 is compared to a triangular wave by a comparator 42, and a duty output 47 is outputted. From a calculated rotating speed ω and a current of a DC bus, the position signal is corrected by a field function circuit 52. Based on this corrected position signal, switch patterns 48 are produced by a switch pattern generator 44, and among the switch patterns 48, signals for driving an upper arm and duty signal 47 are respectively inputted to AND circuits 49 to 51 and AND are taken as a gate signal 43 and sent to a drive circuit.

Title: Production of terephthalic acid
Inventor: UEDA TOSHIHIKO
IPC: C07C51/42
Filed: 1990-07-12
Abstract: PURPOSE:To simultaneously and efficiently remove organic substances and water accompanying waste gases with two or more kinds of adsorbents by cooling discharged oxidation waste gases and condensing condensable gases in oxidizing p-xylene with O2 in the liquid phase using acetic acid as a solvent and obtaining terephthalic acid. CONSTITUTION:p-Xylene is oxidized with molecular oxygen in the liquid phase in acetic acid solvent to produce terephthalic acid. In the process, discharged oxidation waste gases are cooled to condense condensable components. The resultant gases are then brought into contact with two or more different adsorbents to adsorb organic substances and water accompanying the waste gases. Thereby, the aforementioned substances and water are removed from the waste gases. The adsorbents are preferably filled in the form of layers as the adsorbents. Adsorbents prepared by filling active carbon as the adsorbent in the first layer, silica-based adsorbent or zeolite-based adsorbent as the adsorbent in the second layer and further active carbon as the adsorbent in the third layer are especially preferably used. The oxidation waste gases subjected to the aforementioned treatment are useful as a substitute for industrial nitrogen. On the other hand, the removed organic substances can be readily recovered and detoxified.

Title: Carbon jig for firing of si-sic
Inventor: HANZAWA SHIGERU
IPC: C04B35/64
Filed: 1992-07-14
Abstract: PURPOSE:To enable repeating by dozens of times the use of the same carbon jig for firing in the firing of Si-SiC sinter, in which the jig is used in contact with Si-SiC sinters and fusion products of a metal and Si, by specifying the bulk density of the carbon jig. CONSTITUTION:The bulk density of a carbon jig for the firing, used in contact with Si-SiC sinters and fusion products of a metal and Si, is fixed to a range of 1.75 to 1.90 g/cm<3>. It is desirable that the carbon consists of graphite and is a product of CIP molding or extrusion molding. For a bulk density of less than 1.75g/cm<3> cracking may occur in the jig through deterioration accompanying its use by one or two times; for a bulk density exceeding 1.90g/cm<3> a big jig is hard to make and cracking may develop from a difference in density between different locations. It is especially desirable to make the jig from graphite from the viewpoint of resistances to heat and corrosion, and ease of its processing. Consideration of the above enables obtaining a jig which is excellent in durability without the possibility of deterioration through reaction with Si.
