Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a stable constant current output without being affected by the dispersion of the DC current amplification factor of a transistor by making a circuit have a constitution that the voltages of the inversion input terminal and the non-inversion input terminal of an operational amplifier are set so as to be equal and a constant current output is obtained from the base side of an output transistor. SOLUTION: Because the state between the inversion input terminal and the non-inversion input terminal of an operational amplifier 10 is a so-called imaginal short state, the relation of an expression VBE4 +R1.I1/hFE=VBE5 +E1 is formed between the voltages in respective terminals, wherein the VBF4 , the R1, the hFE, the VBE5 and the E1 are the voltage between the base emitters of a transistor 4, the resistance value of a base resister 8, the DC current amplification factor of the transistor 4, the voltage between base and emitter of a transistor 5 and the voltage value of a DC constant voltage source 7, respectively. Therefore, also the output current as the base current of an output transistor 9 becomes I0=E1/R1 and the current is not affected by the DC current amplification factor.

Title: Polishing head
Inventor: KAGAYA MASANAO
IPC: B24B49/00
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain stable polishing load by obtaining inertial force generated to a rotary shaft at the time of a rotary shaft moving with acceleration in the axial direction, and controlling load applied to the rotary shaft by a pressurizer. SOLUTION: In the position of a load detector 117 showing the specified value, depression of a rotary shaft 89 is stopped, and the rotary shaft 89 and a polishing tool 87 are rotated to start polishing. A controller 111 obtains an inertial force generated to the rotary shaft 89 at the time of the rotary shaft 89 moving with acceleration in the axial direction, and a magnetic attracting force acting upon the axial direction of the rotary shaft 89 from the relative position relation in the axial direction between a rotor 107 and a stator 109 of a motor 105, and controls load applied to the rotary shaft 89 by a pressurizer 123, to the specified value. Stable polishing load can thus be obtained even with the grade change of magnetic attracting force and inertial force of the rotary shaft 89 caused by the movement of the rotary shaft 89 in the axial direction.

Abstract: PURPOSE:To well perform confirmation even if the position of a camera changes, by using a reference article to calculate a converting parameter converting a picked up image of a TV camera into a reference coordinates system. CONSTITUTION:The image of parts on a table 10 is picked by TV cameras 1, 2, and the arm 11A grasping the parts and a robot main body 11 are controlled by a robot control apparatus 12 and an image processing unit 3 is connected to the cameras 1, 2 and the apparatus 12. A parameter for converting a scale into a reference coordinates system determined by the kind of a reference article and the relative distance between the cameras 2, 2 is preliminarily calculated. On the basis of this parameter, the scale correction of the picked-up image of the parts to be taught and confirmed is performed. The image after this correction is one under the reference coordinates system and comes to one from a reference position having no relation to the actual positions of the cameras 1, 2. Therefore, regardless of the positions of the cameras 1, 2, the pattern comparison and confirmation of the measured data from the parts to be confirmed and the reference teaching data from the parts to be taught can be performed.
