Abstract: A gas sensor has a porous protective layer disposed on a surface of a sensor element. In this gas sensor, the porous protective layer includes ceramic particles and ceramic fibers. Further, the ceramic fibers are present in the porous protective layer over a range from a front surface to a back surface thereof.

Abstract: A sensor element comprises an element body and a porous protective layer covering a surface of the element body. In this sensor element, the porous protective layer comprises a first layer exposed on a surface of the sensor element and a second layer disposed between the element body and the first layer. The first layer contains ceramic particles and anisotropic ceramics having an aspect ratio of 5 or more and 100 or less, and a part of the first layer is in contact with the element body. Further, a porosity of the second layer is 95 vol % or more.

Abstract: A sensor element of a gas sensor includes: an element base which is a ceramic structured body including a detection part of detecting a target measurement gas component; and a protective layer which is a porous layer provided in at least a part of an outermost peripheral portion of the element base, wherein in the protective layer, numerous convex parts each having a size of 1.0 ?m or less and made up of ceramic microparticles with diameters of 10 nm to 1.0 ?m are discretely formed around numerous ceramic coarse grains having diameters of 5.0 ?m to 40 ?m, the respective ceramic coarse grains are connected to each other directly or via the ceramic microparticle, and a degree of porosity of the protective layer is 5% to 50%.

Abstract: A sensor element of a gas sensor includes: an element base which is a ceramic structured body including a detection part of detecting a target measurement gas component; an outer protective layer which is a porous layer provided in at least a part of an outermost peripheral portion of the element base; and an inner protective layer which is a porous layer having a degree of porosity of 30% to 85%, which is larger than a degree of porosity of the outer protective layer, inside the outer protective layer, wherein an average fine pore diameter of the inner protective layer is equal to or larger than 0.5 ?m and equal to or smaller than 5.0 ?m.

Abstract: The present invention provides a bottom garment that effectively prevents the hem part from losing its shape. The bottom garment of the present invention includes a front part (101), a back part (102), and an intervening fabric member (103). The intervening fabric member (103) includes a crotch part (103A) and a back hemline-forming part (103B) extending laterally from a back end of the crotch part. A front end of the crotch part (103A) is connected to the front part (101). Both outer peripheries (a) at the back side of the front part in the width direction, both outer peripheries (b) of the crotch part in the width direction, and front side right and left peripheries (c) of the back hemline-forming part form hemlines at the time of wearing the bottom garment. In the back hemline-forming part (103B), the shapes of the front side right and left peripheries (c) forming the hemlines at the time of wearing the bottom garment are concave curves or straight lines.

Abstract: The present invention relates to a technology regarding an intelligent network. When an originating subscriber accesses an information offer service by inputting service access information, a service switching point accesses a service control point. The service control point further implements a desired service process corresponding to the service access information, in response to the above step. When the service switching point is informed of the process result, the service switching point is connected to a destination station which accommodates a destination subscriber providing an information offer service, using a method of discriminating an intelligent network call, based on the result processed by the service control point, so that an incoming call to the destination subscriber is established. The object is to regulate certainly a bypass call in a information offer service.

Abstract: A telecommunication system comprises a network for carrying a traffic of information, terminals connected to the network, a transfer unit provided in the network for transferring a call coming in from a calling terminal to a first destination terminal and from the first destination terminal to a second destination terminal. An accumulation unit is provided in the network for accumulating information indicative of occurrence of a transfer of an incoming call each time the transfer of the call occurs from the first destination terminal to another destination terminal. The network further includes a transfer notification unit for notifying the first destination terminal of the occurrence of the transfer by transmitting a control signal from the network to the first destination terminal. A transfer reporting unit is provided in the network for receiving a request signal from the first terminal and for transmitting the call transfer information from the accumulation unit to the first destination terminal.
