Title: Filter for filtration of particulate matters from hot gas flow
IPC: B01D46/24
Filed: 1991-04-05
Abstract: PURPOSE: To ensure simple and highly reliable sealing, thereby preventing a gas from flowing out by sealing a slot between apertures in a supporting part and/or a tube plate and a filter member extendedly existing in these apertures within the slot with a short interval by inserting the seal. CONSTITUTION: The apertures are provided into the supporting part and/or the tube plate 24. Then, around the filter tube 36 inserted into these apertures, a circumferential groove 50 is formed in the wall surface 44 thereof. Then, two or more seal rings 52, which are partially projected from the groove 50, are disposed into this groove 50, whereby the slot between the filter tube 36 and the apperture wall surface 44 is sealed. A chamber 56 is arranged at the inside of each tube plate 24 and a cooling gas is introduced thereinto to cool the seal. Then, the cooling gas is introduced into the slot 48 between the tube and the plate through the apertures 58. Thus, the sealing of the slot is ensured, thereby preventing the gas from escaping into another chamber.

Title: Variable-speed controller for induction motor
Inventor: TAJIMA KOICHI
IPC: H02P27/08
Filed: 1994-03-18
Abstract: PURPOSE:To stably and smoothly operate an induction motor by reducing the gain of the adjusting means of a primary angular frequency computing means in a weaker field region. CONSTITUTION:A magnetic flux adjusting device 4 generates a magnetizing current commanding value IM* from the difference between a commanded magnetic flux value phi2* and calculated magnetic flux value phi2 and a speed adjusting device 5 generates a torque commanding value IT* from the difference between a commanded speed value omegar* and estimated speed value omegar. A current adjusting device 6 calculates the primary voltage commanding value of a motor based on the commanded values IM* and IT* and actual values IM and IT and outputs the calculated commanding value. The estimated speed value omegar is obtained by subtracting a commanded slip frequency value omegas* from a commanded primary angular frequency value omega1*. Even in a low-speed operating region in which the induction voltage becomes lower, detection errors and calculation errors can be reduced and an induction motor can be operated stably and smoothly by correcting the commanded primary angular frequency value omega1* by using a torque current having a large value as compared with the voltage.
