Title: Fully enclosed outer fan type induction motor
Inventor: OZEKI KOJI
IPC: H02K5/02
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To improve cooling performance by forming a frame of double-layer structure which comes into contact with the back surface of a stator and whose inside is a ferrous material and whose outside is a nonferrous material with high heat conductivity. SOLUTION: A double-layer integral frame 7a is constituted by integrating two layers whose inside is made of iron and whose outside is made of aluminum respectively. The heat generated from a stator 3 is transferred to the double- layer integral frame 7a, and heat is absorbed in an outer aluminum layer with high heat conductivity from an inner iron layer for radiation from the surface of the double-layer integral frame 7a with cooling air which a fan generates. It is thus possible to improve cooling performance with a simple structure.

Filed: 1986-07-15
Abstract: PURPOSE:To measure the refractive index of a transparent object directly, by providing a means for irradiating material to be tested with a short pulse light to measure the passage time thereof. CONSTITUTION:A pulse generator for generating an optical pulse with the known wavelength, for example, a device for driving a semiconductor laser with a pulse power source, is prepared and irradiates an object to be tested with a pulse light. To measure a time difference before and after the passage of the pulse light through the object being tested accurately, timing clocks are combined to be compared at each set time as optical clock pulse and pulses of the optical clock are counted in terms of the total of the time difference. To determine the very short time accurately, a streak camera is used to measure the time delay and attenuation in the travelling of light. This enables the measurement of the real and imaginary part of refractive index or those of dielectric constant simultaneously.
