摘要： A gas sensor using oxygen-ion-conductive solid electrolyte layers measures a concentration of a constituent gas such as NOx in a gas mixture such as an exhaust gas mixture of an internal combustion engine. The gas sensor includes a pair of oxygen pumping cells and a sensor cell. Before the constituent gas concentration is measured by the sensor cell, oxygen gas contained in the gas mixture has to be purged because the oxygen gas adversely affects the measurement of the constituent gas concentration. Two pumping cells disposed to face a chamber, into which the gas mixture is introduced, pump out the oxygen gas contained in the gas mixture so that the oxygen concentration is reduced substantially zero. Then, the gas mixture is diffused to the sensor cell where the constituent gas concentration is measured without the adverse influence of the oxygen gas. A marginal ion current which is proportional to the constituent gas concentration is measured by the sensor cell with a high accuracy and sensitivity.

摘要： A drive apparatus supplies electric power to a solenoid of an inductive load from a battery and a capacitor to improve response of the load. The drive apparatus comprises switches for switching between a first state where a negative side of the battery is connected to a positive side of the battery, and a second state where the negative side of the capacitor is connected to the negative side of the battery. When the load is in operation, the voltage applied to the solenoid is raised by the voltage of the battery as the first state, so that the current flowing into the solenoid rises sharply to improve response of the load. When the operation of the load is to be stopped, the electric power to the solenoid is interrupted, and the energy accumulated in the solenoid is recovered by the capacitor as the second state.

摘要： A magnetism property of an armature is increased by including a moving core of sintered metal of 1LSS to 3LSS, and a shaft of a ferromagnetic material. By contrast, a stator core contains 0.005 to 0.1 weight % resin powder, whose particle diameter is set to 50 μm or less, in particular, 25 μm or less, so as to decrease a core loss and increase a magnetism property. The stator core thereby becomes approximately equivalent to the armature in a direct current magnetism property, so that an electromagnetic actuator and a fuel injection valve that are excel in suction force and response are provided.

摘要： A fuel injector is provided which has an improved structure capable of adjusting fuel jet characteristics such as the quantity of fuel to be injected to an engine and a fuel injection time lag after the fuel injector is assembled. The fuel injector includes an air gap adjusting screw and a spring pressure adjusting screw. The air gap adjusting screw serves to change an air gap between a stator and an armature of a solenoid valve to adjust the quantity of fuel to a target one. The spring pressure adjusting screw serves to change a spring pressure urging a valve in a spray hole-closing direction to regulate a spray hole open duration, thereby adjusting the fuel injection time lag or the quantity of fuel.

摘要： In a metal catalyst converter configured of the metal catalyst carrier that holds the catalyst into the honeycomb body created by alternately winding flat sheet and corrugated sheet, a plurality of slit matrix that extend in the direction perpendicular to the exhaust gas direction were arranged on at least one part of the upstream side of the exhaust gas passage. By that a low heat capacity and high heat transfer area in regard to the downstream side of the exhaust gas passage was formed. The upstream portion of the metal catalyst converter on which slit matrix was formed was configured to be covered by outer casing having an air insulation layer. The upstream side of this outer casing was held and fixed to the exhaust gas passage.
