Abstract: An electronic component includes: a first internal electrode which is provided inside an element body and is drawn on a first main surface corresponding to a mounting surface; a second internal electrode which is provided inside the element body, is provided at a position different from the first internal electrode when viewed from a third direction, and is drawn on the first main surface; a third internal electrode which is provided inside the element body, is provided at a position facing the first internal electrode and the second internal electrode in the third direction, and is drawn on the first main surface; wherein the first internal electrode and the third internal electrode face each other in the third direction to form a first capacitor portion, and wherein the second internal electrode and the third internal electrode face each other in the third direction to form a second capacitor portion.

Abstract: A plastic lens manufacturing device includes a preparation tank in which a lens material is prepared; a suction unit which exhausts a gas in the preparation tank; a thermometer which measures a temperature of the lens material that is prepared; a revolution indicator which measures the number of revolutions of a stirrer for stirring the lens material when the lens material is prepared; a control unit which determines abnormality of a preparation state based on data obtained from the thermometer and revolution indicator; a temperature regulation unit which regulates a temperature inside the preparation tank; an inhibitor introduction unit which introduces a reaction inhibitor into the preparation tank; and a programmable logic controller which is connected to the control unit and controls operations of the temperature regulation unit and the inhibitor introduction unit based on determination made by the control unit.

Abstract: A laser beam reflector for reflecting a laser beam from a laser oscillator in a direction away from said laser oscillator includes a mirror holder, a mirror retainer removably coupled to the mirror holder, a bend mirror coupled to the mirror retainer for reflecting the laser beam, and a detecting device for detecting a positional relationship between the mirror holder and the mirror retainer. A laser beam cutting machine utilizes the laser beam reflector. When the mirror holder and mirror retainer are coupled properly, laser oscillation is performed. When the mirror retainer and holder are coupled improperly, laser oscillation is terminated immediately by a control device of the laser beam cutting machine.

Abstract: An automatic welding machine which welds two materials separated by a groove that may be of varying cross-section along its length. Cross-sections at the two ends of the welding line are input by a variety of means. The machine then calculates an oscillating welding pattern along the groove so as to deposit a constant density of weld material.

Abstract: An automatic welding apparatus for performing welding along the circumference of abutted pipe ends, wherein the apparatus can be taught and operate in accordance with data related to reference positions and welding paths along semicircumferences of the abutted ends. A welding head is driven along a guide attached to one of the two pipes. The welding head is first positioned to reference points and then moved along the guide in two upward directions to the ends of welding lines, thereby to teach the apparatus the welding operations to be performed. Subsequently, the apparatus is operated to carry out welding in accordance with the instructed operations.

Abstract: A method for performing automatic circumferential welding around the circumference of a butt joint of a fixed pipe or the like. First, an initial set-up operation is performed wherein a welding head is moved around the welding circumference while producing pulses indicative of the amount of movement of the welding head. The number of pulses required to move the welding head one complete revolution is counted. Next, angles at which the welding conditions are to be changed are specified. These angles are converted to the form of pulses from a start point using the number of pulses previously counted. For the actual welding operation, pulses are again counted while moving the welding head. Each time the pulse count reaches one of the specified angles, a controller instructs a new set of welding conditions to the welding head.
