Title: Induction machine for driving inverter
Inventor: ISHIBASHI AYANORI
IPC: H02K3/493
Filed: 1982-02-16
Abstract: PURPOSE:To reduce the noise and vibration even if non-sinusoidal wave power source such as an inverter is employed by inserting a wedge made of conductive material of magnetic property into a slot of a stator core. CONSTITUTION:A magnetic flux 9 is provided from a stator core 1 through an air gap 7 to a rotor core 8. When a wedge 6 made of a conductive material of magnetic property such as iron is inserted into the opening 5 of a slot 2, part of the magnetic flux does not flow toward the air gap 7, but passes through the wedge 6 as designated by magnetic flux 10 and does not flow toward the core 8. This flux 10 is leakage magnetic flux, thereby increasing the leakage magnetic flux. In this manner, ripple of harmonic component of the voltage and current waveform from non-sinusoidal wave power source such as an inverter to an induction machine is reduced, thereby largely decreasing the noise and vibration.

Abstract: PURPOSE:To enlarge a visual field angle by a simple method, by constituting the titled crystal display panel, so that an optical path difference of a liquid crystal is set to a range of 0.7-0.9, and also, a polarizing angle by a polarizing plate is adjusted to a range of 20-50 deg. from the rubbing angle. CONSTITUTION:A full line in the figure shows a rubbing direction 1 of an oriented film which is provided on the upper and lower substrates, and a crossing angle phi1 is a rubbing angle. Also, a broken line shows a polarizing direction 2 of a polarizing plate which is set onto the upper and lower substrates, a crossing angle phi2 shows a polarizing angle and the difference phi2-phi1 is a polarizing angle DELTAphi. In such a way, by adjusting the rubbing angle phi1 and the polarizing angle phi2, a distinct image is obtained. At the time of a value of the polarizing plate angle DELTAphi is fixed to -20 deg., and in such a state, a value of a visual field angle characteristic exponent beta is derived by varying a value of DELTAn.d in such a state, the value of beta approaches '1' within the range of 0.7-0.9. Therefore, a liquid crystal display panel whose visual angle dependency is small is formed by holding a value of the optical path difference DELTAn.d, and a value of DELTAphi, in 0.7-0.9, and an optimum value of a range of 20-50 deg..
