Title: Flip flop circuit
Inventor: TAKAHASHI TOORU
IPC: H03K3/2885
Filed: 1984-04-23
Abstract: PURPOSE:To make sure set and reset operations possible by inserting a resistance between the common emitter point of data holding transistors TRs and that of TRs for set signal input and reset signal input. CONSTITUTION:When a high level is impressed to a reset input R, a bias voltage is impressed to the base-emitter junction of a reset input TRQ1 extra by the potential difference of a resistance R5. Therefore, the TRQ1 is turned on more easily than a data holding TRQ3, and sure reset is possible. Frequency characteristics are not degraded because a resistance is not inserted to the feedback route of the signal. Further, the output logical level is not shifted neither reduced because level shift is not performed in the VCC side. Consequently, sure set and reset operations are attained.

Abstract: PURPOSE:To prevent a tread belt reliably from running off a tire base body in a tire by which the tread belt can be mounted on/ demounted from the tire base body. CONSTITUTION:Wedge shape recessed parts 6 are formed on the outer peripheral surface of a tire base body 1.
