Title: Roll
Inventor: OKA TSUTOMU
IPC: C25D7/06
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent cracking in a roll in the case a shaft is subjected to welding or the like by prescribing the elongation at the center part and both edge parts in the axial direction of an alloy layer formed around a core material. SOLUTION: An alloy layer 4 composed of an Ni-Cr-Mo series alloy is formed around a steel tube 1. This alloy layer 4 is composed of an alloy in which the elongation at the center part in the axial direction is regulated to 1% and an alloy in which the elongation at both edge parts in the axial direction is regulated to >=4%. These alloys can be obtd. by changing the compsn. of the raw material in powder compacting. In the production of a roll 8, a shaft 5 is shrinkage-fit to both edges of the steel tube 1, and the boundary part 6 between the steel tube 1 and the shaft 5 is welded to integrate both. At this time, even if heat in the welding transfers to the alloy layer 4 and thermal stress is generated in the alloy layer 4, the elongation in the vicinity of the edge parts of the alloy layer 4 is large, by which the edge parts of the alloy layer 4 elongate to relax the thermal stress.  As a result, the generation of cracking in the alloy layer 4 can be prevented.

Title: Method and apparatus for control of vector of induction motor
Inventor: ARANAKA SHINJI
IPC: H02P21/18
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus which do not require information on a speed by a method in which, on the basis of the product of a primary angular frequency multiplied by the magnetic-flux-estimated approximate value of a prescribed d-axis component in a primary magnetic flux and on the basis of other axial components in a primary voltage or of the estimated approximate value of the voltage, the primary angular frequency is decided by a computing and processing operation and a phase decision process is used. SOLUTION: The same direction as a secondary magnetic flux as a two-dimensional vector amount is set as a d-axis, and an axis at right angles to the direction is set as a q-gxis. A primary angular frequency which is generated by a new primary-angular-frequency generator 11 is integrated and processed by an integrator 9, it is input to a sine-signal generator 10, and a sine signal which corresponds to an integrated value is generated so as to be output to vector rotating devices 6a, 6b as phase information on a d-q coordinate system.  At this time, the new frequency-angular-freguency generator 11 generates a remaining voltage value which is obtained by subtracting a drop voltage, generated at a time when the q-axis component of a primary current is made to flow to a primary resistance and an overall primary leakage reactance, from the q-axis component instruction value of a primary voltage, and it generates the magnetic-flux-estimated approximate value of a d-axis component in a primary magnetic flux on the basis of the d-axis component in the primary current. Then, the primary angular frequency is decided in such a way that the remaining voltage value equals the product of the magnetic-flux-estimated approximate value and the primary angular frequency.

Abstract: PURPOSE:To allow water to flow by allowing an inflow port and an effluence port to communicate each other through manual operation even in power failure, by arranging a manually operating valve for the communication and cut-off between the inflow port and the effluence port, into a bypass passage for the communication to a passage. CONSTITUTION:An opening hole 33 is formed onto the peripheral wall of a cylinder body 15 and serves as a bypass passage for the communication between a flow passage on an inflow port 2 side and a flow passage on an effluence port 3 side. Said opening hole 33 is freely opened and closed by a valve 34, and the communication between the inflow port 2 and the effluence port 3 is cut-off by manually operating the valve 34 through a cock 36. Since electromagnetic coils 11 and 12 are not excited in power failure, a plunger 14 is pressed by a spring 30, and a valve 16 is kept in closed state. If the valve 34 is opened by operating the cock 36, the opening hole 33 is opened to form a bypass passage, and water flows in the direction of arrow D.
