摘要： An ejector apparatus moves a lift core extending through a core of a component of a resin molding mold to form an undercut portion in a molded piece and is installed so as to be capable of moving obliquely with respect to the core surface in a longitudinal direction. An ejector plate is arranged between the core and a base plate below the core, so as to be capable of moving up and down. A slide path is formed in the ejector plate extending in a direction in which a lower end of the lift core makes relative horizontal movement during ascent and descent of the lift core. A slide base is movably arranged in the slide path and coupled to the lower end of the lift core. A guide rod imparts a moving force within the slide path to the lower end of the lift core during ascent and descent of the ejector plate.

摘要： A position-sensorless motor control device has a superposer that superposes, on the drive current with which the motor is driven, a superposed current having a different frequency than the drive current, a superposed component extractor that extracts, from the motor current fed to the motor, the γ-axis and δ-axis components of the superposed current, and a controller that controls the motor so that the direct-current component of the arithmetic product of the extracted γ-axis and δ-axis components of the superposed current converges to zero.

摘要： A device comprising an oxygen-sensitive element to be disposed in a combustion gas exhausted from a combustor to detect deviation of actual air/fuel ratio from a stoichiometric ratio. The element is a combination of two oxygen concentration cells each having a solid electrolyte layer, a measurement electrode layer formed on one side of the electrolyte layer, a reference electrode layer formed on the opposite side and covered with a shield layer. Either measurement electrode layers or reference electrode layers of the two cells are connected to each other, and a constant DC voltage is applied to the element to force a current to flow through solid electrolyte layers of both cells to cause migration of oxygen ions therethrough, from the measurement electrode to the reference electrode in one cell and reversely in the other. The device has a circuit to make a comparison between a fixed reference voltage and an output voltage developed between the measurement and reference electrodes of one cell of the element to produce a high-or-low level control signal according to the result of the comparison. The output voltage is independent of the internal resistance of the element and is scarcely affected by the temperature of the element.

摘要： An apparatus comprising a probe having an oxygen ion conductive solid electrolyte layer, a potentiometer and a DC power source connected to the probe. The probe comprises a porous and electronically conductive reference electrode layer on one side of the solid electrolyte layer, a similar measurement electrode layer on the other side of the electrolyte layer and a separation layer of an inactive material on the outer side of the reference electrode layer. The separation layer or the solid electrolyte layer, or both, has a porous structure and is formed such that the reference electrode communicates with an exterior atmosphere only through this porous structure, while either the separation layer or the electrolyte layer serves as a substrate of the probe. During measurement, the DC power source keeps a current flowing through the electrolyte layer between the two electrode layers to maintain a reference oxygen partial pressure at the interface between the electrolyte layer and the reference electrode layer.
