Abstract: PURPOSE: To identify a chip which is not conformable definitely to a required speed regulation without requiring any special test equipment by coupling a speed measuring circuit with an external clock and a control processor so that the output from a counter will be a function of the speed of an integrated circuit chip. CONSTITUTION: A time reference counter 50 for incrementing the count with each device clock pulse delivers a count A (N bits) to an end count detector 52. The detector 52 compares the output from the counter 50 with a predetermined value and generates a stop signal 54 upon matching. The stop signal 54 is delivered to a control logic circuit 23 and oscillation of a ring oscillator 21 is interrupted by returning a countable signal to a high value thus stopping the count operation of a counter 22. Count of the counter 22 is delivered on a data line 38 to a processor 40. The processor 40 calculates the speed of a specific chip under test by determining the count of a speed circuit during a time reference interval.

Abstract: PURPOSE: To increase the uniformity of etching by holding plasma in a three-pole reaction chamber and using a plasma confining multipole magnetic field generated from a large number of bar magnets arranged on the side face and upper surface of the reaction chamber. CONSTITUTION: Bar magnets 30 are stationarily fixed along the outer periphery of an electrode 12 and another bar magnets 32 are buried in an upper electrode 10, with the electrode 10 being left by a prescribed thickness for separating the magnets 32 from a reactive volume 20.

Filed: 1989-03-31
Abstract: PURPOSE:To make a measurement accurately with high reproducibility by holding a turbine rotor obliquely in the manner of changing the height of one of a pair of open type bearings connected to vibration pickups. CONSTITUTION:The heights from a pedestal for a pair of the open type bearings 3-1, 3-2 which are connected with the vibration pickups 2-1, 2-2 provided on the pedestal and also furnished with receiving parts of V-shaped cross section, are positioned so as to be high for the end surface of thickness side of the inner bearing ring 7 for an angular ball bearing and low for the end surface of thinner side. For example, an angle theta for a revolving shaft 6 of the turbine rotor 8 to a horizontal line is made to be 0.3 deg.<=theta<=3 deg. when center positions of both end surfaces for the inner ring 7 are positioned at the same height. With such a constitution, a shift to the right direction at the R part of inner ring 7 is restricted and also the shift to the left direction can be restricted by a force apt to slide down to the right direction. Consequently, the measurement can be made at the position where the bearings 3-1, 3-2 are always positioned at the substantially constant position to the rotor 8.
