Abstract: According to an embodiment, a driving assistance device includes a recognizer configured to recognize a surrounding situation of a mobile object, a decider configured to decide whether or not to prompt a driver of the mobile object to perform acceleration or deceleration on the basis of the surrounding situation, and a notification controller configured to cause a speaker to output a notification sound for prompting the driver of the mobile object to perform the acceleration or deceleration on the basis of a decision result. The notification sound is a notification sound obtained by continuously changing a structure of a sound.

Abstract: The method includes: determine a first integrated value by integrating measured values of widths of reference patterns (210A) belonging to a first group; determine a second integrated value by integrating measured values of widths of reference patterns (210B) belonging to a second group; performing second matching between patterns on an image of a second region and corresponding CAD patterns; determining a third integrated value by integrating measured values of widths of patterns (220A) belonging to a first group; determining a fourth integrated value by integrating measured values of widths of patterns (220B) belonging to a second group; and determining that the second matching has been performed correctly when the magnitude relationship between the third integrated value and the fourth integrated value coincides with the magnitude relationship between the first integrated value and the second integrated value.

Abstract: A substrate inspection jig for use in inspection of an electrical property of a printed board to be inspected on which an electronic component is mounted includes a spacer which is mounted on the printed board to be inspected, a conductive plate which is connected to the spacer, and is disposed along an arrangement direction of electrode terminals of the electronic component to be inspected, and a fastener which fastens the spacer on the printed board to be inspected, wherein the plate is disposed above the printed board to be inspected so as to avoid contact with the printed board to be inspected, and a predetermined potential of the printed board to be inspected is set to the plate through the spacer or/and the fastener.

Abstract: A vulcanizable rubber composition comprising a blend which is prepared by micro-dispersing a polyolefin resin (B) in an ethylene-.alpha.-olefin-nonconjugated polyene copolymer rubber (A) comprising ethylene, a C.sub.3 -C.sub.20 .alpha.-olefin and a nonconjugated polyene in a molten state and in which the mean diameter of dispersed particles of the polyolefin resin (B) is 2 .mu.m or below and the (B) to (A) weight ratio ranges from 5/95 to 50/50. The micro-dispersion of a polyolefin resin (B) can easily be attained by kneading the components (A) and (B) together with compounding ingredients (such as reinforcement, filler, softener, vulcanization accelerator, vulcanizing agent and so on) in a rubber kneader, through the resin (B) is essentially difficult of micro-dispersion. Further, the composition enables the provision of rubber articles having a high and constant quality at a low cost, because the resin (B) can well be dispersed by conventional rubber kneaders in a short time without fail.
