    • The time and trouble of a mismatch cause analysis after logical equivalence verification can be reduced, and design and verification TAT can be shortened. A logical equivalence verifying device performs logical equivalence verification between two circuits, and displays the result of the logical equivalence verification. A preprocessing section 7 performs structural matching so as to determine whether there are portions corresponding in circuit structure to each other in corresponding logic cones of the two circuits. An internal DB 5 records the results of the structural matching as an identifier for each element. A subcone extracting section 8 extracts, as a subcone, a collection of elements, which are mutually to one another and have the same identifier, from each logic cone. A verifying section 9 performs logical equivalence verification between the two circuits for each of the extracted subcones. A display control section 10 displays only those subcones for which the logical equivalence verification has resulted in mismatch.
    • 可以减少逻辑等价验证后不匹配原因分析的时间和麻烦,可以缩短设计和验证TAT。 逻辑等价验证装置在两个电路之间执行逻辑等价验证,并显示逻辑等效验证的结果。 预处理部7执行结构匹配,以便确定在两个电路的相应逻辑锥中是否存在与电路结构相对应的部分。 内部DB 5将结构匹配的结果记录为每个元素的标识符。 子提取部分8从每个逻辑锥体中提取彼此相互并且具有相同标识符的元素集合作为子单元。 验证部分9对于每个提取的子晶体执行两个电路之间的逻辑等价性验证。 显示控制部10仅显示逻辑等同性验证导致不匹配的那些子会话。

    • A rotary connector, which is generally used for the steering device of an automobile, for establishing electrical connections via a flexible flat cable between an electric circuit fixed to the steering column and an electric circuit attached to the steering wheel. The rotary connector of the present invention has guiding means for the flat cable for smooth winding. Guide piece 13 is formed at recess 12C on inner cylinder 12B, with one end formed in one piece with the bottom surface of lid 12A of inner case 12. A proximity to the inside end of flat cable 5 is inserted into gap 14 between the inner wall of guide piece 13 and the periphery of recess 12C disposed on inner cylinder 12B of inner case 12. Flat cable 5 is then guided out from the edge surface of edge portion 13A formed so as to tilt the tip of guide piece 13 in the periphery direction. It is thus possible to provide an easy to assemble and economical rotary connector with the number of parts minimized.

    • A turning direction indicator device includes an actuator that rotates by an operation of an operating lever so as to be positioned at neutral and operational positions, a cover that has a lower surface having a guide groove therein extending in a rearward direction toward the cancel cam, a cam body that has an upper surface sliding with respect to the lower surface of the cover, an urging spring that urges the cam body in the rearward direction, a release element that rotates together with the actuator, and a grease provided between the upper surface of the cam body and the lower surface of the cover. The cam body includes ridges projecting from the upper surface of the cam body. The turning direction indicator device suppresses a hitting noise produced by the cam body and the release element with such a simple structure, and operates reliably.
