Title: Range finder
Inventor: DAIMON TERUYUKI
IPC: G02B7/32
Filed: 1995-02-02
Abstract: PURPOSE: To increase the freedom of the design of a range finder and to make it possible to perform multiple-point distance measurement without enlarging the area of the entire sensor. CONSTITUTION: With respect to at least one sensor of a plurality of sensors 11-13, the opposite side with regard to the side of a light projecting means is deviated at a specified interval in the direction perpendicular to the base line. Furthermore, sensor areas 11a, 12a and 13a are expanded into the opposite direction with respect to the side of the light projecting means. Without any change of the respective arrangements of a plurality of the neighboring sensors, the received reflected light image of an object for distance measurement located at the side of the short distance is received at the expanded sensor area part. Thus, the highly accurate distance measurement on the side of the short distance is maintained.

Abstract: PURPOSE:To calibrate the temperature of a thermal gravity measuring apparatus by utilizing the melting point of a material which is used as a temperature reference material. CONSTITUTION:A rod body 11 pushes the upper part of a reference material contained in a sample receiving pan 4 which is suspended with a suspending wire 6 from a beam 1. A means 13 fixes the rod body 11 to a base stage 12 and pushes the rod body 11 at a constant load. A means 8 detects the change in load. These parts are provided. At the time of temperature calibration, a reference material whose melting point is known is contained in the sample receiving pan 4. The surface of the material is pushed with the rod body 11. The rod body 11 is fixed to the base stage 12 with the means 13 under the state wherein a constant load is added. The reference material releases the load from the rod body 11 at the stage when the temperature of the material reaches the melting point. Therefore, the load from the rod body 11 disappears, and the load of the sample receiving pan 4 is changed. The output of a temperature detecting device 9 when the load change occurs is compared with the melting point of the reference material. Thus, the error in the temperature detecting device can be detected.
