Filed: 1993-06-16
Abstract: PURPOSE:To enable fast response even if a disturbance is applied by supplying a control signal for dividing an actuator to a current supplying means. CONSTITUTION:A detecting means 16 detects a deviation between a focus position of a light spot and the prescribed reference focus position, and sends an follow-up deviation signal to a follow-up deviation change rate estimating means 20 and a control signal generating means 22. The means 20 supplies a signal being an estimate value of a time change rate of a deviation to the means 22 based on a follow-up deviation signal. Thereby, the means 22 outputs a control signal for driving an actuator 11 in the direction of canceling a deviation with a larger time change rate than that of an estimated deviation to a current supplying means 18, the means 18 supplies a driving current to the actuator 11 based on a control signal. And the actuator 11 moves a focus position of a light spot in the direction of canceling a deviation with a larger value than a time change rate of an estimated deviation by driving at least one part of a light spot generating means 8 in accordance with a driving current.

Title: Ic test equipment
Inventor: HAMA HIROYUKI
IPC: G01R31/26
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To prevent warm air from directly colliding against a main frame and restrain the inner temperature from increasing, by changing the direction of warm air discharged from a test head upward, downward, etc., with an air direction changing means. SOLUTION: The air direction changing means 40 is fixed on a panel surface of a main frame 10. The changing means 40 is constituted of a box member which acts as a duct and a ventilation fan and makes warm air 23 discharged from a test head 20 flow into a suction port of the box member. The ventilation fan changes the direction of the warm air 23 flowing from the suction port upward or downward, or sideways and discharges the warm air 23. Thereby, the warm air 23 is prevented from directly colliding against the main frame 10. Thermal insulating material is used as a closed surface which faces the suction port of the box member, and heat of the warm air 23 is not transmitted to the main frame 10. Hence, by installing an air direction changing means 40, the main frame 10 is not directly heated by the warm air 23 and the temperature rise of the main frame 10 can be restrained.
