    摘要: An angular velocity sensor for detecting angular velocity by converting deflection caused by the coriolis force into an electrical signal. The sensor includes a vibratory member having at least three main surfaces including a first main surface having a driving transducer provided thereon, and second and third surfaces substantially perpendicular to the first main surface respectively, and being parallel to each other, the second and third main surfaces having detecting piezoelectric transducers, respectively. Additionally, support members are connected to the second and third main surfaces to respectively support vibration-steady points of the vibratory member. At least one longitudinal end portion of the vibratory member has a cross-section in such a manner that a length between the second and third main surfaces is shorter than a length of the first main surface. In this manner, the sensitivity of the angular velocity sensor is improved.

    摘要: To increase the stability and sensitivity of a vibrational angular velocity sensor, the vibrator is airtightly housed within a glass vacuum casing whose inside surface is coated with a metallic film. Further, conductive lead pins electrically connected between vibrator signal terminals and a printed circuit board for a signal processing circuit and fixing pins mechanically fixed to the printed circuit board are arranged with a constant length outside the casing in parallel to each other. Further, two vibrator support pins are fixed to the glass casing by glass material. To obtain a high vacuum within the glass casing, a subcasing including a getter is connected to the casing through a connecting tube cut off or sealed after evacuation.

    摘要: The headlight moving apparatus comprises a yaw rate sensor, a headlight position sensor, a vehicle speed sensor, a CPU, and a headlight actuator. The CPU calculates an appropriate headlight turning position on the basis of these three sensor signals. Since the yaw rate sensor can directly detect the vehicle turning motion and direction, it is possible to move the headlights right and left more reliably. Therefore, the adjusted headlights can brighten remote forward road surface when the vehicle runs along a curved road.

    摘要: This invention is directed to form a homogeneous film in a via hole formed in a semiconductor device using Bosch process. The via hole that penetrates through a predetermined region in a semiconductor substrate is formed by etching the semiconductor substrate from one of its surface to the other by the Bosch process using a mask layer as a mask. Next, the mask layer is removed. Then, scallops are removed by dry etching to flatten a sidewall of the via hole. Following the above, an insulation film, a barrier layer and the like are formed homogeneously in the via hole.

    摘要: A monitoring method for moving vehicles allows the presence of danger to be determined from the magnitude of an optical flow vector. The optical flow vector is detected as a movement of a single point on an object taken over two images, with one image taken at a preceding time and the other image taken at succeeding time in a series of images. A long and narrow window set in a radial direction from a focus of expansion (FOE) of the earlier image is moved in the same direction on the latter image. An optical flow vector of a target point is defined by a vector connecting the midpoint of a location of a subsequent window and the midpoint of a location at which the long and narrow window is set in the earlier image. The location of the subsequent window is determined by minimizing the sum of absolute values of differences in luminance between the long and narrow window and an area of the latter image overlapping such long and narrow window. The optical flow calculation area is limited to areas in which a difference in luminance between the earlier and latter images exceeds a predetermined threshold, and any influence from scenes outside the road boundaries and from lane-dividing lines or other symbols drawn on the road surface is removed in calculating the optical flow.

    摘要: Disclosure is a luminous pointer made of a light emission element of the inorganic substance dispersion type, high in accuracy of reading, and low in cost. The light emission element of the inorganic substance dispersion type is shaped as a rod, and includes a linear metal core, an electrically-insulating reflective layer made of an enamel and disposed on the core, a fluorescent light emission layer which is made of an enamel and a fluorescent substance dispersed therein and is disposed on the reflective layer, an electroconductive film disposed on the light emission layer and capable of being electrically connected to the core, and an outer electrically-insulating layer disposed on the film. The film has at least one slit which has a width smaller than the diameter of the luminous pointer and extends as a luminously visible portion in the longitudinal direction of the film. An intermediate electrically-insulating layer made of an enamel may be provided between the light emission layer and the film. The film is manufactured by applying an electroconductive paste or plating with a metal. In the light emission layer, the dispersed fluorescent substance may be provided only near the slit of the film.
