Title: Contact detecting method for arc furnace facility
Inventor: KASUGA TOSHIAKI
IPC: F27D21/00
Filed: 1990-06-12
Abstract: PURPOSE:To prevent switching on in a short circuit state in a furnace so as to protect a furnace transformer by supplying an electric current by means of another power supply connected to the secondary side of the furnace transformer in order not to turn it into the exciting voltage of the transformer so that it can be detected that an electrode is in contact with scrap based on the intensity of the current flowing then in an electric circuit. CONSTITUTION:When an electrode is in contact with scrap, an electric current flows from a current-limiting resistor 8 to an electrode 4 and scrap through a water-cooled cable 3. The impedance of the water-cooled cable 3 and the contact resistance between the electrode and the scrap are extremely small as compared with impedance Z of a surge absorber 7. Therefore, the intensity of the flowing current depends on impressed voltage and a current-limiting resistance value. When the electrode is not in contact with the scrap, the electric current flows from the current-limiting resistor 8 through the surge absorber 7 grounded on the secondary side of a furnace transformer. In this case, the intensity of the flowing current depends on the impressed voltage and the impedance Z of the surge absorber 7.

Abstract: PURPOSE:To prevent erroneous action by providing a waveform shaping circuit to arrange, the signal from the second changing-over circuit changing-over corresponding to a light emitting element to emit the light signal from a photodetecting element to a constant voltage value based upon the driving signal. CONSTITUTION:The optical pulse signal outputted from light emitting diodes L1-Ln is detected by phototransistors PT1-PTn to photodetect respectively the signal, and inputted through the second changing-over circuit 7 to a waveform shaping circuit 2. For the signal from the second changing-over circuit 7, the switching noise of the signal at the quiescent time of the optical pulse and the waveform due to the disturbance light are deleted based upon a driving signal (a) and the peak value at the time of inputting the optical signal is arranged to the voltage of the constant level. The output signal of the waveform shaping circuit 2 is correctly converted to a coordinate signal at a CPU 5 through an amplifier circuit 3. Thus, since the electric current supplying quantity to the light-emitting diodes L1-Ln can be also decreased and the calorific value in the device is made smaller, the device is not influenced by the strong disturbance light such as the solar light, and the action can be stably executed.

Abstract: PROBLEM TO BE SOLVED: To form a thin film in an extremely uniform thickness on a semiconductor wafer. SOLUTION: An ultrasonic vibration generator is excited in a direction of an arrow C with respect to a rail 14 and transmits the vibration of the rail 14 via a roller 12 in contact with the rail 14 and a strut 10 to a table 8.

Filed: 1990-06-11
Abstract: PURPOSE:To make it possible to cut a profile by constituting a ridgeline angle of a rear mirror so that it may be controlled to make rotation to a desired polarization angle where said rear mirror is a right angle roof type reflecting mirror. CONSTITUTION:An oscillator comprises a rear mirror, which is a right angle roof type reflecting mirror 10 and an output coupling mirror 4. In the roof reflecting mirror 10, light enters each reflected plane at an incident angle of 45 degree. In this case, a linear polarization light parallel to a ridgelin 10a provides the maximum reflectance. Since laser oscillation is a kind of positive feedback phenomenon, laser light is oscillated under this linear polarization condition. When it is arranged to make the roof reflecting mirror 10 rotatable around an axis which crosses the ridgeline 10a, it is possible to rotate the direc tion E of the field vector. When profile cutting processing is carried out, if the angle of the ridgeline 10a of the roof reflecting mirror 10 is rotated under control so that the direction E of the field vector of a laser beam 13 may con form to the direction of a processing passage, it will be possible to cut and process at the maximum absorption rate all the time.

Abstract: PURPOSE:To relax centralization of a stress to two directions and to improve durability of a piston by a method wherein a force exerted in the longitudinal direction of a piston pin and in a direction extending vertically to the longitudinal direction of the piston pin is exerted on an intermediate part between the two directions. CONSTITUTION:Notches 7 are formed in the peripheral edge of the opening part of a cavity 3 only in a direction of an approximately 45 deg. in the longitudinal direction of a piston pin 6 based on a piston axis 8. The rigidity of a notch 7 part is reduced to a value lower than that of the peripheral edge of the opening part of other cavity. Thus, a part of a force exerted in the longitudinal direction of the piston pin 6 and a direction extending vertically to the longitudinal direction of the piston pin 6 is exerted on the notch part, being a position on which an inertia force owing to reciprocating movement of a piston 1 and the pressure of combustion gas are most apt to exert, and the notch part is deformed. A force exerted in the longitudinal direction of the piston pin 6 and in a direction extending vertically to the longitudinal direction of the piston pin 6 is decreased to improve durability of the piston 1.
