摘要： There is disclosed an electrostatic holding apparatus in which a voltage is applied to an conductive electrode covered with an insulating dielectric layer in order to cause the insulating dielectric layer to electrostatically attract an object. The main component of the insulating dielectric layer is ceramic containing 0.1-30 wt. % of an atomic metal, and the volume resistivity of the metal-containing ceramic at 20° C. is 108-1013 &OHgr;·cm. The metallic element is Mo or W. In the electrostatic holding apparatus, since the volume resistivity of an insulating dielectric layer of an electrostatic attraction portion is decreased, a strong electrostatic force can be generated. Also, there can be maintained the capability of allowing removal of an object at the time of stopping application of voltage. Further, since neither fine cracks nor pores remain in the insulating dielectric layer after sintering, the withstand voltage is high.
摘要翻译：公开了一种静电保持装置，其中电压施加到被绝缘电介质层覆盖的导电电极，以使绝缘介电层静电吸引物体。绝缘介电层的主要成分是含有0.1-30wt。原子金属的％，并且含金属陶瓷在20℃下的体积电阻率为108-1013欧米加。金属元素是Mo或W.在静电保持装置中，由于静电吸引部分的绝缘电介质层的体积电阻率降低，所以可以产生强的静电力。此外，在停止施加电压时可以保持允许物体移除的能力。此外，由于在烧结之后绝缘介电层中既没有微细的裂缝也没有孔，所以耐电压高。

摘要： A stitch balancing thread tension device for a sewing machine, the body of which is inserted into the opening portion of the sewing machine body, wherein the thread tension device body for supporting a stem on which a pair of tension discs are fit, comprises a projecting portion which contacts the outer side surface of the sewing machine body and pawls which are retained at the circumferential edge of the opening portion by the inner side surface of the sewing machine body for clamping the sewing machine body therebetween. The pawls are elastically invaginable into the thread tension device body to release the sewing machine body from clamping. Since the thread tension device can be attached to or detached from the sewing machine body in one-shot operation, the operability is remarkably improved in efficiency.
摘要翻译：一种用于缝纫机的线圈平衡线张力装置，其主体插入到缝纫机主体的开口部分中，其中用于支撑杆的一个张紧装置本体用于装配一对张紧盘，与缝纫机主体的外侧面接触的部分，以及通过缝纫机主体的内侧面保持在开口部的周缘的爪部，用于将缝纫机主体夹持在其间。棘爪弹性地不能进入线张力装置主体以使缝纫机主体不被夹紧。由于可以在一次性操作中将线张力装置安装到缝纫机主体上或从缝纫机主体拆卸，所以效率显着提高了可操作性。

摘要： An improvement is proposed in an electrostatic chuck having a chuck head comprising an electrode layer sandwiched between a backing insulating layer and a frontal insulating layer, which comes into contact with a work piece when the electrostatic chuck is working, by which the electrostatic chuck can exhibit a large electrostatic attractive force by increasing the voltage applied between the electrodes without the problem of dielectric breakdown in the insulating layer and a leak current occurring on the surface of the work piece. The improvement can be obtained by forming the frontal insulating layer in a two-layered structure consisting of a high-dielectric layer made from a material having a dielectric constant of at least 50 at a temperature of 20.degree. C. and a frequency of 1 MHz and a high-resistivity layer made from a material having a volume resistivity of at least 1.times.10.sup.12 ohm.cm at 20.degree. C., the high-dielectric layer being interposed between the electrode layer and the high-resistivity layer.

摘要： An air-fuel ratio control system for internal combustion engines has an air-fuel ratio sensor mounted in an exhaust pipe of an internal combustion engine and is adapted to produce an output indicative of the air-fuel ratio of a mixture supplied to the engine, on the basis of the composition of exhaust gases in the exhaust pipe. The air-fuel ratio sensor is provided with an electric heater for heating the air-fuel ratio sensor. The system further has an engine operation sensor adapted to sense, through detection of the state of the ignition switch, whether the engine has been stopped. When the engine operation sensor has sensed that the engine has been stopped, the electric heater is supplied with power for a predetermined time after the stop of the engine so as to evaporate any water content clinging to the air-fuel ratio sensor.
