Filed: 1981-07-01
Abstract: PURPOSE:To improve the response in the transient state of an induction motor by composing a control system with the differentiated secondary crossing magnetic flux as the component of the secondary crossing magnetic flux in a perpendicular direction. CONSTITUTION:A speed reference from a speed reference control resistor is inputted through a resistor 23 to a speed controlling operational amplifier 22, the speed feedback signal of the output of a speed detector 13 is further inputted to the amplifier 22, and the output becomes a torque signal T*. When the signal T* is inputted to a divider 26 and is divided by a secondary crossing magnetic flux reference phi2*, the output becomes an armature current signal I2*. A slip frequency Somegae* and the output (1-S)omegae of the detector 13 are added by an adder 29, which in turn outputs a primary frequency signal omegae*.

Title: Diamond saw for cutting stone of the like
Inventor: INOUE NIROU
IPC: B28D1/12
Filed: 1981-07-03
Abstract: PURPOSE:To prevent deviation in cutting direction in such a way that the outer peripheral part sectional shape is held to be in concave shape, by arranging the tip which provides a portion where diamond grinding grain is not contained at the intermediate part of the tip, on the outer periphery of its base plate. CONSTITUTION:The columnar space at the center part of the tip in which the content of diamond grinding grain is less than at both outer side parts is integrated by the material which is composed of mixture of lead, lead alloy, copper, copper alloy, aluminum, aluminum alloy, nickel, or graphite particle integrated by coating copper and copper or copper alloy particle, or a plastic material. Thus, since the inner face of the thin part which is situated at both side parts of the columnar space 8 which has been provided in the middle of the tip is not brought into direct contact with the partner material, the life of the tip can be extended. Besides, because the outer peripheral section of the tip is ground into concave shape as seen at 5 in the figure, horizontal force does not arise, and deviation phenomenon does no appear in the cutting direction.
