IPC: G01B11/02
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a dimension inspection machine which can inspect a work for external size with high accuracy in a short time. SOLUTION: A work inspection table on which a work W is fixed is transferred from a first position to a second position. When the table is transferred, the external size of the work W in the X-direction is optically detected by means of an X-direction size detecting sensor 51 in which a light projecting section 51B and a light receiving section 51A are positioned on both sides of the transferring route of the table. When the blade main body W2 (light transmissive section) of the work W is inspected, a shielding member (54A) controls the light receiving section 51A so that the section 51A may not receive excessive light. Similarly, the size of the work W in the Y-direction is optically detected by means of a Y-direction size detecting sensor which is positionally deviated from the sensor 51 in the transferring direction of a work transferring means.

Inventor: KAWAKITA TADAHIRO
IPC: G01C9/06
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized and high-accuracy inclination angle sensor by measuring the frequency of a pulse wave output from a high resolution current/frequency converting circuit to measure a very small change of the converging position. SOLUTION: Even if a measuring machine where a device is installed is inclined, only the free liquid level 3' keeps a vertical surface in the direction of gravity, so that the angle of incidence and the reflecting angle in the free liquid level 3' of light from a light emitting element 1 change. Accordingly, the converging position 4 on each light receiving surface of 4-split photodetectors changes depending on the inclination angle. The output of a photoelectric converter of each light receiving surface is input to a signal select circuit 6, and a signal of sum of four outputs selected to be combined according to the control of a inclination angle calculating part 8 is input to a current/frequency converting circuit 7.  In the converting circuit 7, four input currents are converted to pulse waves respectively having frequencies respectively corresponding to the input currents, output to a pulse counter 8' in time series, and during fixed time, pulses are counted to measure the frequency corresponding to each input current from the count value. The inclination angle calculating part 8 finds the converging position according to the above frequency information to calculate the inclination angle.

IPC: G06F21/10
Filed: 1989-07-12
Abstract: PURPOSE:To prevent an illegal copying action of a program by securing such a constitution where the editing of a message is possible only when an exclusive editing tool is used. CONSTITUTION:A message file element 10 is edited by means of an exclusive editing tool 1 and released as a well-defined message file 20. Therefore an execution type module 30 does not work without the message file 10, and the file 10 is not visible and cannot be edited if the tool 1 is not used. As a result, the file 10 is protected by means of the tool 1 and kept at the release side. Then an access is always given to the file 10 at start. As a result, the release program itself can be protected from the illegal copying actions as long as the program contains the file 10 serving as a protection key.
