Title: Receiving otical device
Inventor: ENDO TAISUKE
IPC: G01B11/00
Filed: 1991-06-13
Abstract: PURPOSE:To obtain an optical system with a short full length, which can confirm the optical axis at an optional wavelength, and with a high stability of optical axis, by dividing a relay lens into two parts, and setting an interference filter by forming the part of parallel light with the two convex lenses. CONSTITUTION:The light input to an objective lens 1 passes through a pin hole 5 focused by the objective lens 1. The receiving field is determined by the opening diameter of the pin hole 5 and the focal distance of the objective lens 1. The light which has passed through the pin hole 5 is made into the parallel light by the first convex lens 10, passes through an interference filter 3, and it is focused to a receiving element 7 by the second convex lens 11. Since a part of the parallel light is formed between the relay lenses, and an interference filter is set at the part of the parallel light in such a way, it is unnecessary to provide optical parts between the objective lens and the pin hole, and the full length of the optical system is made shorter. And since an interference filter is eliminated between the objective lens and the pin hole which determine the optical axis of the receiver optical system, the optical axis can be inspected by a light of the wavelength other than the permeating wavelength of the interference filter.

Title: Testing method for temperature-increase of rotating electric machine
Inventor: KANDA AKIO
IPC: H02K11/00
Filed: 1992-06-03
Abstract: PURPOSE:To shorten the time required for tests and to save power consumption by computing and outputting the final estimated temperature when the deviation between the actually measured value of the temperature and the computed temperature with a model is within the specified range. CONSTITUTION:The temperature-increase test is started, and the measurement of time is performed in a temperature-increase-testing-time measuring device 9. The actually measured temperature value thetac is acquired from a stator coil 2 through a stator-coil-temperature measuring device 5, and dtheta/dt is computed in a [d9/dt] operating device 10. The value of thermal resistance R is computed in a thermal-resistance operating device 12 based on thetac and dtheta/dt. The time change pattern of the thermal resistance R is made to be the numerical expression. The time change pattern of the thermal resistance R having the closest value of R in a thermal resistance memory device 14 is selected. In a temperature-increase-value operating device 11, the computed temperature theta with a model is computed by using the selected pattern. In an adder 7, the actually measured temperature value thetac is compared with the computed temperature theta. The fact that an adaptive algorithm 8 and the deviation epsilon thereof are in the specified range is judged. When the deviation epsilon is within the specified range, the final estimated temperature phin is computed by using the selected time change pattern of the thermal resistance R. When the deviation epsilon is outside the specified range, the time change pattern of the thermal resistance R is corrected.
