    • A gas sensor is disclosed as having a gas sensor element, supported with a cylindrical housing, which is covered with an atmosphere-side cover fixedly secured to the cylindrical housing. The atmosphere-side cover fixedly supports a seal member having a ventilation bore and a plurality of lead wire inserting bores formed around the ventilation bore. A filter member is fusion bonded to the seal member in a fusion-bonded area at temperatures above 300° C. The fusion-bonded area is formed in an entire circumference in gastight effect at an area outside an outer periphery of the ventilation bore and has no clearance, wherein suppose that the ventilation bore has an opening surface area A at the end face of the seal member and a region surrounded with the fusion-bonded area has a surface area B, the relationship is established as A

    • The disclosed device generates a plurality of pixel data in an XY coordinate system. The pixel data includes first pixel data generated on a first sweep line, according to a distance from a transmitting source, based on an echo of a detection signal from the source toward a first direction, and second pixel data generated on a second sweep line, according to a distance from the source, based on an echo of a detection signal from the source toward a second direction different from the first direction. The device includes a module for converting the first and second pixel data into data in the XY coordinate system, a module for generating pixel data of an interpolation target pixel located between a first pixel as an observing pixel on an interpolation axis parallel to X-axis or Y-axis and a second pixel as a corresponding pixel on the same interpolation axis, based on the pixel data on the first and second sweep lines.

    • An improved structure of a gas sensor is provided which is designed to minimize thermal damage to a water-repellent filter installed in a base end portion of the gas sensor. The gas sensor has an elastic seal installed in an opening of the base end portion of the gas sensor and an air cover assembly made up of a main cover and a filter cover. The filter cover is crimped to form at least two necks which establish joints of the filter cover to the main cover through the water-repellent filter. At least one of the necks is used to retain the elastic seal within the main cover. This structure locates the water-repellent filter farther away from the top of the gas sensor exposed to intense heat, thereby minimizing the thermal deformation or deterioration of the water-repellent filter.
    • 提供了一种改进的气体传感器的结构,其被设计成最小化对安装在气体传感器的基端部分中的防水过滤器的热损伤。 气体传感器具有安装在气体传感器的基端部的开口中的弹性密封件和由主盖和过滤器盖构成的空气盖组件。 过滤器盖被压接以形成至少两个颈部,其通过防水过滤器将过滤器盖的关节建立到主盖上。 颈部中的至少一个用于将弹性密封件保持在主盖内。 该结构将防水过滤器远离暴露于强热的气体传感器的顶部远离,从而最小化防水过滤器的热变形或劣化。
