Title: High-performance rotating machine core and manufacturing method therefor
Inventor: KAIDO TSUTOMU
IPC: H02K1/18
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To maintain a core for a driving rotary shaft, and at the same time to control deterioration in the performance of the core by measuring clamp strain generated in the core when fixed to an outer-periphery frame in a clamped state, by adjusting the clamp conditions for the core based on the measurement and controlling the clamp strain within a specific range. SOLUTION: A measuring primary field coil is energized until the flux detected with the secondary coil for a flux route analysis becomes constant, and the coercive force of the yoke 5 of an outside core 1 is detected with the current waveform. By clamp the strain caused by an outer-periphery frame 3, compression is applied to the yoke 5 of the outside core 1 for generating the clamp strain, thus increasing the coercive force for increasing the iron loss in the outside core 1 and the excitation force, and hence measuring the clamp strain, at the same time the iron loss in the outside core 1, and the increase of the energizing by coercive force measurement. As the result of the coercive force measurement, when it is decided that the clamp strain is too large, the inner diameter of the outer-periphery frame 3 in a product and the shape of the outside core 1 are adjusted.

IPC: G01R33/12
Filed: 1984-08-20
Abstract: PURPOSE:To enable the measurement of coersive force of a ferromagnetic body simply and quickly with a small unit, by arranging a test piece and a sensor in a fine clearance between cores arranged in magnetizing the demagnetizing coils to rotate them relatively. CONSTITUTION:A test piece holder 42 is set in a fine clearance between cores 14 and DC excitation current is allowed to flow to a magnetizing coil 11 from a DC voltage varying circuit 21 to magnetically saturate a test piece 43 by magnetization. Then, a motor is made to run to turn the test piece holder 42 while excitation current from a DC voltage varying circuit 22 applied to a demagnetizing coil 12 is increased sequentially to generate a magnetic field in the direction opposite to that of a magnetic field of the magnetizing coil 11. Then, the difference in the electromotive forces between detection coil 52 and 53 is supplied to an X-Y recorder through the charging of a capacitor so that the residual magnetization of the test piece 43 is offset by the magnetic field of the demagnetization coil 12. Thus, the coersive force of the test piece 43 is calculated from the value of excitation current of the demagnetization coil 12 when the outputs of the detection coils 52 and 53 equal.

IPC: B26D1/14
Filed: 1991-06-17
Abstract: PURPOSE:To prevent an operator from being injured by an exposed moving blade, or prevent this blade from being damaged, during, for example, a jam disposal with the cover member being kept open. CONSTITUTION:In a main device body 1 of a laminate device, a lower frame 2b supports a top cover 2a in a freely openable manner. On the top-cover 2a side, a moving blade 33a of the sheet-material cutting device 33, and a protector 60 freely rotatable in the directions of arrows A1 and A2 are disposed. The protector 60 is formed in the form of a semi-cylinder and is connected to the lower frame 2b via a cover arm 80. By this cover arm 80, the protector 60 takes, at the time of opening the top cover 2a, a retreat position K2 permitting the moving blade 33a to be exposed and takes, at the time of closing the top cover 2a, a closure position K1 permitting it to cover the moving blade 33a. The movement of the protector from the retreat position K2 to the closure position K1 and vice versa is made in interlocking relation with the opening/ closing operation of the top cover 2a. When opening the top cover 2a, the protector 60 automatically covers the moving blade 33a. Therefore, the operator is prevented from touching on the moving blade 33a to get injured during, for example, his operation of jam elimination. Nor is the blade 33a damaged.
