Abstract: An earthquake disaster prevention system having: an estimation section to estimate a size of an earthquake from a P-wave of the earthquake detected by the earthquake detector; a stopping control section to control to stop the motion of the operation device when the size of the earthquake estimated by the estimation section exceeds a stopping reference value; a calculation section to calculate at any time the size of the earthquake from the S-wave of the earthquake detected by the earthquake detector; a convergence judgment section to judge convergence of the earthquake by judging whether a predetermined earthquake convergence condition is satisfied from the size of the earthquake calculated by the calculation section; and a resumption control section to resume a predetermined motion of the operation device stopped by the stopping control section when the earthquake is judged to have converged by the convergence judgment section.

Abstract: Operating information of a measuring device is extracted through analysis of at least a part program to execute measurement or output of measurements. Information facilitating maintenance and control of the measuring device is automatically generated from the operating information history.

Abstract: In coordinate and surface texture measurement in which measurement control is performed by a part program, a part program is analyzed to extract measurement information or measurement condition. The measurement condition is rewritably stored such that optimal measurement conditions of an actual measurement can be reflected in a part program, and such that the actual measurement conditions can be added to subsequent measurement control.

Abstract: A gage inspecting apparatus includes a jog dial 56A for controlling an amount of displacement of a measuring spindle 22 at a time when the position of the measuring spindle 22 is finely adjusted, and a shuttle ring 56B for controlling the driving direction and driving speed of the measuring spindle 22 at a time when the position of the measuring spindle 22 is roughly adjusted. The relationship between the amount of rotation of the jog dial 56A and the amount of displacement of the measuring spindle 22 can be set in correspondence with a scale interval of the gage.

Abstract: A linear measuring machine is provided, the linear measuring machine having a base (11), a column (12) disposed on the base, a slider (14) elevatable along the column and an elevation driving mechanism (44) including a motor for lifting and lowering the slider. The linear measuring machine further includes a touch-and-back mechanism for driving the elevation driving mechanism in a direction for a probe (13) to move away from a measurement surface of the workpiece after fetching a detection value of a displacement sensor (45) when the probe touches the measurement surface of the workpiece and for stopping the elevation driving mechanism.

Abstract: A height gauge capable of being moved while confining a positional relationship between a probe and a workpiece with an easy posture is provided. A handle (21) is provided on a side of a column (12) having a probe (13) adjacent to a base (11). An air-floatation control switch (31) for controlling supply and cut-off of air to an air-floatation mechanism (19), a repeat switch (32), a cancel switch (33) are provided to the handle (21).

Abstract: A focus detection unit including an optical system employing an image sandwiching method is disclosed. In the focus detection unit, a double slit mask (12) forming double sight lines is disposed on the optical axis of a lamp 10 while a single slit mask (16) forming an single sight line is disposed on the optical axis of a lamp (14). A triangular pole prism 18 is provided, consisting of first and second side surfaces, which together constitutes an edge, and a plane opposing the edge. The prism (18) is disposed such that the double and single sight line are able to irradiate the first and second side surfaces. The prism reflects the incoming lines toward a plane before the right-angle edge. Before the edge of the prism (18), a projection lens (20) is provided for forming images of the double and single sight lines which have been reflected by the prism (18) and separated by a mask (22), at a both aiming line imaging position 100. The images are projected onto a workpiece.
