    摘要: This invention relates to a bi-directional digital amplifier for use in cellular switching circuits and in cellular computers and which is capable of propagating a signal in respectively opposite directions without degrading the signal and which is capable of delimiting such propagation in either or both directions. The amplifier requires no clock signals for operation, will not latch up in response to noise and is well suited for construction in the form of an integrated circuit chip.

    摘要: A clamping instrument for use for occluding blood vessels and other fluid ducts in an animal or a human body has a slender tubular shaft provided at one end with a lateral clamping jaw and at its other end with a hand piece. A thin wire is slidably disposed in the shaft and has a lateral clamping jaw at one end disposed in confronting clamping relation with the fixed jaw on the shaft. The wire is slidable through the hand piece and extends rearwardly therefrom with such extension being mounted or attached to the hand piece to prevent turning movement thereof and spring means biasing the movable jaw on the wire into clamping relation with the fixed jaw.
