Filed: 1985-02-21
Abstract: PURPOSE:To determine automatically and correctly whether the remaining amount to be ground reaches an allowable range with ease without interrupting grinding operation by mounting a sensor in the vicinity of a dressor. CONSTITUTION:To perform numerical-controllingly grinding operation for an initial grinding allowance assuming that a grinding wheel 15 is not worn and then the grinding wheel 15 is dressed in accordance with a prescribed amount of cutting which is set in advance by an in-process system. At this instance, a sensor 25 detects a reaction which a dressor 27 receives from the grinding wheel 15. If the detected reaction is greater than a prescribed threshold value, it is determined automatically that the amount of wear of the grinding wheel 15 in the preceding grinding cycle is so small that a grinding of a workpiece which is proportional to the amount of wear of the grinding wheel 15 has proportional to the amount of wear of the grinding wheel 15 has been reached an allowable range. On the contrary, if the detected reaction is less than the prescribed threshold value, it is determined automatically that the workpiece has not been sufficiently ground in the preceding grinding cycle and the grinding cycle must be repeated furthermore.

Title: High frequency trap circuit
Inventor: OGINO HITOSHI
IPC: H01P1/201
Filed: 1991-01-30
Abstract: PURPOSE:To narrow 3dB drop band width and to increase an attenuation value even in a compact circuit by connecting a capacitor to a TEM resonator is series. CONSTITUTION:This high frequency trap circuit is constituted of a serial circuit consisting of the capacitor 10 and the TEM (transverse electro magnetic wave) resonator 20 connected between a signal transmission line 40 and a ground point. Since the TEM resonator 20 is used instead of a herical coil, a high Q value can be obtained as a trap circuit and only an unnecessary component can be attenuated in a narrow band. The shape of the circuit can be comparatively compacted as compared with a case for obtaining equivalent performance by the herical coil and non-adjustment can almost be attained by using parts worked by trimming or the like.
