Title: Ear drum thermometer
Inventor: TAKAKURA KEISHIRO
IPC: G01K7/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide an ear drum thermometer of simple structure which determines temperatures by capturing infrared light emitted from a small area. SOLUTION: It has a concave shaped elliptical reflecting mirror 1 in a frame body 5 of the ear thermometer and is set a pyroelectric infrared ray detector 2 at the F1 focus 6, and another F2 focus 7 is set at the front of an opening part 4 of a top of a cylinder 3. And the cylinder 3 of the thermometer is inserted into an acoustic meatus 10 search a peak of the amount of infrared light at the ear drum part. The infrared light 8 from the ear drum goes through the F2 focus 7, impinges on the elliptical reflecting mirror 1 and incidents on the pyroelectric infrared ray detector 2. Thus only the thin beam that pass through the F2 focus 7 incidents on the pyroelectric infrared ray detector 2. As the infrared light from the acoustic meatus 10 does not incidents on the pyroelectric infrared ray detector 2, it is possible to take a temperature of the ear drum with the high accuracy.

IPC: H01S3/109
Filed: 1992-12-25
Abstract: PURPOSE:To provide a resonator built-in type optical second higher-harmonic wave laser system wherein the temperature of a crystal can be controlled by an easy and less expensive structure by keeping the non-linear optical crystal at a temperature higher than the room temperature by means of a heater. CONSTITUTION:The entire body of a KTP of crystal length 5mm is coated with a copper cover except for an optical path area. A space between the KTP and the copper cover is filled with thermal conductive silicon rubber and a coated manganin wire is wound round the copper cover to make the copper cover serve as a heater. In order to increase a thermal contact between the manganin wire and the copper cover, thermal conductive silicon rubber is applied to the area where the manganin wire is to be wound and then the wire is wound and fixed before the silicon rubber is dried. After that, heat insulating silicon rubber is applied in the uniform thickness into the wound manganin wire and then the manganin wire is covered with a Teflon protective cover. Thus, the second higher-harmonic wave output can be stabilized by a very simple method, the heating of the non-linear optical crystal.
