Title: Rotation strength testing apparatus
Inventor: YAMAGISHI YOSHIKATSU
IPC: G01M13/00
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To separate influence by a vibration from that by a thermal expansion by detecting by two optical position detectors a position change in a radial direction of a concentric light-shade pattern of an outer circumferential part of a sample impeller, obtaining a difference of the position changes and measuring the temperature in a noncontact manner. SOLUTION: A concentric light-shade pattern is plotted on a surface of a core plate of a sample impeller 7, and the change in a boundary position between the light and shade is detected by optical detectors 4, 5 set symmetrically with respect to the center of a rotary shaft. A difference of detected amounts by the optical detectors 4, 5 becomes a change amount of a diameter from which influences of a vibration are offset. A temperature change ΔT of the sample impeller 7 is measured by a noncontact thermometer 6, and a change amount ΔT×α×d because of the temperature change is calculated with the use of a diameter (d) of the boundary position of the light and shade and a coefficient of linear expansion α, so that the change amount is offset.  Accordingly the change in an outer shape of the sample impeller 7 can be measured in real time during a rotation test, and a rotational frequency when a plastic deformation is brought about can be easily detected.

Filed: 1994-12-19
Abstract: PURPOSE: To prevent the unexpected manual selection of the vehicular travel direction, regarding a device for a vehicular travel speed control formed so as to control a travel speed in both forward and backward directions on the basis of a target speed established and inputted via an operation member. CONSTITUTION: An operation member 12 can be selectively shifted from a reference position P into a 'forward travel zone' and a 'backward travel zone' at both sides of the position P through a manual operation. During the travel of a vehicle in a forward direction, a travel restriction member 60 is projected into a space between the reference position P and the 'backward travel zone' within the travel locus of the pin 32 of the member 12, thereby preventing the member 12 from being shifted into the 'backward travel zone'.  Also, when the vehicle is traveling in a backward direction, the member 50 is projected into a space between the reference position P and the 'forward travel zone' within the locus, thereby preventing the member 12 from being shifted into the 'forward travel zone.' In addition, when the vehicle is at rest, the member 50 is caused to retreat to an area outside the locus, thereby releasing the prohibition of shift.
