Patent JP-H02180407-A (JP)
Title: Cassegrain antenna
Inventor: SHIRAISHI AKIRA
IPC: H01Q19/19
Filed: 1988-12-29
Abstract: PURPOSE:To improve a VSWR characteristic in each frequency band by arranging an apex matching plate, which prossesses a two-layer reflecting surface consisting of polarization selective plate and a metal reflecting plate, and respectively reflects different two frequency bands whose polarization is orthogonal to each other, at the apex of a sub-reflecting mirror. CONSTITUTION:An apex matching plate 5 is provided at the apex of a sub-reflecting mirror 2, and it is composed of the two-layer structure of a polarization selective plate 6 and a metal reflecting plate 7. For example, when the high frequency band is the horizontal polarization and the low frequency band is the vertical polarization, the electromagnetic wave of the horizontally polarized wave in the high frequency band radiated from a primary radiator 3 is reflected by the apex matching plate 5, and there is a reflected wave returning to the primary radiator 3. For the wave reflected by the apex matching plate 5, since the direction of the grid of the polarization selective plate 6 and the polarized direction of the incoming wave is in a relation forming an angle 90 deg., the wave is transmitted through the polarization selective plate 6, and brought by the metal reflecting plate 7. By determining the size and a set position d2 of the metal reflecting plate 7 to apply the condition so that the polarized waves may be mutually canceled, the excellent VSWR characteristic can be obtained.

Title: Tool length measuring device for nc machine tool and tool length measuring method using the same
Inventor: IWAMA MASATOSHI
IPC: B23Q17/22
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a high-accuracy tool length measuring device for use with a novel NC machine tool capable of determining the tool tip position without damaging the tool and a tool length measuring method using the same. SOLUTION: This tool length measuring device has a detector rod 51 fixed immovable to an NC machine tool. The detector rod 51 is characterized in that, when seen from above, its central part has a cross section which is so shaped as to be the nearest to the start position of an end mill 84. Only when a tip of the end mill 84 comes into contact with the central part of the detector rod 51, the end mill 84 is temporarily withdrawn. The, there will be no contact between the end mill 84 and the detector rod 51 when the end mill 84 is moved in the direction squarely crossing the direction of the withdrawal, which enables the recognition that the center of the detector rod 51 now overlaps the center of the end mill 84. A device designed as such improves on the accuracy of tool length measurement, thereby enabling a higher-accuracy cutting process.

Title: Probe mechanism and coordinate measuring device using the same
Inventor: SHIOZAWA HISASHI
IPC: G01B21/20
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a vertical displacement type probe mechanism designed so that the pressure to a subject to be measured by the probe is made very small by a simple mechanism without decreasing measuring accuracy and to provide a coordinate measuring device using the same. SOLUTION: The weight of a probe 21 is supported against the structure of a probe case 22 via a tension coil spring 27, whereby the pressure to a subject M for measurement can be made very small, so that a frictional force can be reduced in the measuring direction. Also, because the tension coil spring 27 is disposed so that the line of application of its force passes the center C of support when an air bearing 23 supports the probe 21, the spring force of the tension coil spring 27 does not produce moments whereby the axis of the probe 21 is tilted from the vertical axis. The air bearing 23 supports the probe 2 with sufficient rigidity to prevent measuring accuracy from decreasing.
