摘要： PROBLEM TO BE SOLVED: To reduce the unbalance of frictional force among each member, the shaft bending of a rotor and thermal deformation vibrations by making the length of a creepage block, one end of which is held to a retaining ring, longer than that of other creepage blocks. SOLUTION: A field winding 2 in a rotor drum section 9 is housed in a slot, and fixed by a wedge 3 through a creepage block 1A. That is, the field winding 2 and the wedge 3 and both ends in the axial direction of the creepage block 1A are held by a retaining ring 10. The length LCB of the creepage block 1A, one end of which is held to the retaining ring 10, is formed in size longer than the thermal extension range of the field winding 2 during rotating conduction and in size longer than the length of other creepage blocks 1B. Accordingly, the unbalance of frictional force among each member generated by the thermal extension of the field winding at end sections in the axial direction of a drum section in a rotor during starting operation can be reduced.

摘要： PURPOSE:To provide a delay time calculation method which can shorten the computer processing time needed for the delay analysis where the wiring resistance is taken into consideration. CONSTITUTION:A 1st delay time Tc where the output resistance of a primitive element is taken into consideration is calculated by a delay calculation expression which applies the output resistance Ron of the primitive element, the wiring parasitic capacities C1-C3 and the input capacities Cin1 and Cin2 of the primitive element of the next stage. Then a 2nd delay time TL where the wiring resistance is taken into consideration is calculated by the analysis of a circuit network which is equalized by an RC delay circuit network including the wiring resistances R1-R3, the capacities C1-C3 and the capacities Cin1 and Cin2. Then both delay times Tc and TL are added together so that the delay time is known between the primitive elements.

摘要： PURPOSE:To obtain a device for inspecting/evaluating wedge loosening of rotary electric machine to objectively evaluate the wedge loosening taking input data variation into account. CONSTITUTION:An electrical signal from a detecting means 12, which shows the behaviour of wedge when a striking means 11 gives a shock, is analysed by analysing means 13 and 16 with different parameters. The analysis information is evaluated in fuzzy inference mechanisms 15 and 18 respectively through the criteria 14 and 17 of skillful inspector. Therefore, the variation of input data due to individual differences and the positional relation between a slot and the rotating shaft can be evaluated, resulting in evaluating the wedge loosening objectively. When a membership function is set, the conventional creteria are taken into account to easily compare with the past inspection results for examination.

摘要： PURPOSE:To improve reliability, by forming a resist film covering a P-channel MISFET region into a pattern not transversing a gate electrode of an N-channel MISFET. CONSTITUTION:A resist film 11 covering a P-channel MISFET region is shaped into a pattern which does not overlap the gate electrode 101 of an N-channel MISFET. Thus, the resist film 11 covering the P-channel MISFET region is not in contact with the gate electrode 101 of the N-channel MISFET. As a result, it is possible to prevent deterioration or breakdown of a gate insulating film 8 caused by charges 14 flowing into the gate electrode 101 of the N-channel MISFET from the resist film 11 which has been charged up. Thus, reliability of an integrated circuit device can be improved.

CONSTITUTION:Insulating spacing pieces 4 are inserted along end coils 2a protruding from a stator core 1 and over the whole length between said end coils. Said insulating spacing pieces 4 are FRP obtained by combination of epoxy resin with reinforced fiber formed into semicircles having collar faces as base material, the radial dimension of each semicircle is larger than the half of the gap dimension between end coils 3, and said spacing pieces are inserted between end coils 3 in such manner that respective collar faces 4a are stuck together and respective pairs of said pieces 4 face each other. Also, the apex parts touching end coils 2a of said semicircles of the insulating spacing pieces 4 inserted between end coils 3 wind and fasten insulating tight binding materials 5 and are fixed to said end coils 2a. In this manner, said insulating spacing pieces do not directly rub the insulating layers of said end coils.

摘要： PURPOSE:To prevent a slot insulation from receiving a damping force, by providing an elastic member between a slot bottom member and said slot insulation. CONSTITUTION:After a slot cover 3 was inserted into a slot made in the barrel of a rotor, an elastic member 6 is applied to a slot cover 3 and slot side wall. The suitable quantity of said elastic member 6 is such that the upper end of a slot insulation 2 emerges slightly from the bottom face of a wedge 5 when said slot insulation 2 is gently placed on the elastic member 6. Then, the slot insulation 2 is arranged on said elastic member 6 and a field coil 1 is inserted therein. Further, a creepage block 4 for insulation is arranged on said field coil 1 and said wedge 5 is inserted thereon. In this case, the upper end of said slot insulation 2 is arranged to contact with the bottom face of said wedge.
