Abstract: PURPOSE: To ensure the protection of a guide vane and its control mechanism by holding a link (connecting a guide ring and a guide vane) between a pair of friction plates through which a pin pierces.  
     CONSTITUTION: A pair of friction plates 14A and 14B through which the middle portion 16 of a connection pin 10 pierces are placed on the face and back of a link 6, and a nut 12 engaged with the screw portion 17 of the pin 10 is tightened so as to hold the link 6 between the friction plates 14A and 14B. The force transmission between the link 6 and a lever 7 is effected through the frictional force by which the plates 14A and 14B hold the link 6. The tightening force is determined by the stress generated in the middle portion 16 of the pin 10. Initial stress control is most reliable as the tightening force control.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To eliminate a skew and to perform an accurate measurement that depends on a timing by providing a skew correction element in units of each IC (DUT) to be measured in an evaluation board. SOLUTION: Input and output to DUT 1-1 to DUT N-n are performed via a skew correction element D. A skew is generated in a drive signal that is supplied from the INPUT until the DUT 1-1 to DUT N-n are reached due to the routing of a pattern. At the same time, a skew is also generated in the output of the DUT 1-1 to DUT N-n. It is corrected and each skew is set to 0 at input pins a-d of the DUT 1-1 to DUT N-n in the case of a drive signal and at output pins (e)-(h) for an evaluation board for output. In that case, an area with the largest delay is used as a reference with correction 0 and an area with the least delay is used as reference with the largest correction for correction. For example, a delay line is used as a correction element D.
