Title: Interference measuring instrument
Inventor: IWAMOTO YOJIRO
IPC: G01B9/02
Filed: 1987-12-24
Abstract: PURPOSE:To form clear interference fringes corresponding to a sample which differ in refractive index and to eliminate deterioration in measurement accuracy by arranging a 1/2lambda plate and a 1/4lambda plate in an optical path and adjusting the quantity of light by polarization, and eliminating the need for an attenuation plate. CONSTITUTION:A linear polarized laser beam from a coherent light source 10 has its optical axis slanted by the 1/2lambda plate and is split by a polarization beam splitter 36 to an optical path 40a to the sample 16 to be measured and an optical path 40b to a reference plane mirror 18 at a specific light quantity ratio. The 1/4lambda plates 42 and 44 provided on the optical paths 40a and 40b delay the phase of an optical-axis directional polarized component of the supplied light beam 1/4 wavelength behind that of a vertical polarized component. Consequently, an incident beam from the 1/4lambda plate 44 to the splitter 36 becomes perpendicular to the split surface and an incident beam from the 1/4lambda plate 42 to the splitter 36 becomes parallel to the split surface, so both beams are sent out to the optical path 40c. A polarizing plate 46 forms interference fringes between reference light and measurement light and the interference fringes are sent to a work camera 22.

Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a traffic monitoring system capable of transmitting images obtained before and after the occurrence of abnormality to a center at the occurrence of abnormality. SOLUTION: When earthquake occurs, an earthquake center 14 calculates an SI value and transmits the calculated SI value to the center 1. A disaster prevention controller 23 in the center 1 stops the image updating of an ITV camera device 11 in response to the reception of the SI value. Thereby the device 11 leaves images obtained before and after the occurrence of earthquake. The controller 23 transmits an image transmission request signal for transmitting the image data of Δt sec before and after earthquake occurrence time to the device 11. The device 11 transmits the image data of the time band to the center 1. Consequently the scale of damage caused by abnormality occurrence can be accurately grasped.

Heat from the resistor wire 21 is cooled by the coolant. A wire stopper material is coated on the surface of the outer pipe 31 for insulating and fixing the resistor wire. Cement material is used as the wire stopper material. The wire stopper material may be also mixture of the cement material with resin or fiber.  Thereby, cooling efficiency is improved since the cement material has large heat conductivity.
