Abstract: PURPOSE:To ensure the lifting speed of an electrode and surely get rid of an electrolytic product in a gap in an electro-chemical machine for finishing a three-dimensional machining face by carrying out the vertical movement of the electrode by combining motor driving and air driving. CONSTITUTION:At the time of carrying out the diesinking electric discharge machining of a workpiece 4, a using electrode 2 is fixed while fixing the workpiece 4 to a workpiece fixing device 5 and the power source of an electrolytic finishing machine 1 is thrown in, operating an air feeding device 12. The parameter of a machining condition, etc. is inputted by an input device 10 and the electrode 2 is lowered and brought into contact with the workpiece 4, and this position is stored by a control device 9 as a machining original point A. An electrolyte is fed into a machining vessel 13, the electrode 2 is lifted up and set, and a pulse current is fed from a power source device. As the pulse current is cut off, a control signal is outputted from the control device 9 to a pulse motor 6 while simultaneously outputting a control signal to a solenoid value. Due to these signals, the lifting up of the electrode 2 is simultaneously carried out by means of the motor and air driving.

Title: Projection aligner
Inventor: FUJITA ITARU
IPC: H01L21/30
Filed: 1987-03-02
Abstract: PURPOSE:To enable high precision correction and maintenance of optical characteristics such as image focusing positions and multiplying factors, by forming an enclosed space between optical elements in a projection optical system and detecting volume variations of gases in the air. CONSTITUTION:One of detection pipes 16 of an optical system temperature sensor S is tied with an air hole 13 and the other of their pipes is tied with an atmosphere around a projection optical system 3. Inner pressures of optical element air gaps G1 to G4 are kept equal to a pressure of the atmosphere around the projection optical system 3 through a magnetic fluid 17 in the pipe 16. Inductance of the detection coil 18 is uniquely defined in accordance with a position of a magnetic fluid 17, and positional variations inside the magnetic fluid 17, which depend on volume variations of the air in the projection optical system 3, can be detected from the output value of the voltage 19. Detection of minute temperature variations is thus enabled, and results of this detection is reflected in the projection optical system or the like, so that optical characteristics such as projection multiplying factors and image focusing positions can be corrected and maintained with high precision.

Title: Electromagnetic induction type coordinate detecting device
Inventor: HAMANAKA YOICHI
IPC: G06F3/03
Filed: 1986-03-04
Abstract: PURPOSE:To reduce power consumption without lowering the accuracy of detection by selecting rectangular wave having waveform so as to reduce tertiary harmonic that becomes the cause of lowering of the accuracy of detection due to rectangular wave driving. CONSTITUTION:As an input coil 3 is excited and driven by the rectangular wave, electric power efficiency is nearly 100%. Further, an outside capacitor 30 and a resistor 31 of a monostable multivibrator 24 are adjusted to make the width T of pulses outputted by the monostable multivibrator 24 (2pi)/3. Consequently, a signal F becomes the rectangular wave current of positive direction and negative direction while sandwiching the period of cessation of pi/3, and does not contain tertiary harmonic component that deteriorates the accuracy of detection. Accordingly, high power efficiency can be obtained without lowering the accuracy of detection. By selecting the value of a capacitor 22 to make the capacitor 22 and the input coil 3 cause series resonance to basic frequency, the harmonic component of higher order is further lowered and the accuracy is improved.
