Abstract: A semiconductor device package includes a plurality of input leads and an output lead, a plurality of transistor amplifier dies having inputs respectively coupled to the plurality of input leads, and a combination circuit configured to combine output signals received from the plurality of transistor amplifier dies and output a combined signal to the output lead.

Abstract: A slogging wrench (10) comprising: a ring socket (36) for receiving a nut or a bolt head (NBH, NBH?); an elongate body (20) for receiving blows from a mass to transmit torque to the ring socket; and a tool-free locking mechanism (22,24,26,26?,28,30) for retaining a nut or a bolt head in the ring socket. The locking mechanism comprises a slider (22) operable to engage a nut or a bolt head in the ring socket; a channel (24) for guiding movement of the slider towards and away from the ring socket; and an actuator (30,74) manually operable to move the slider with respect to the ring socket. The channel (24) opens into the ring socket (36) via an internal periphery (40) of the ring socket. The locking mechanism comprises a resilient member (34) biasing the slider (22) towards a nut or a bolt head (NBH, NBH?) in the ring socket (36).

Abstract: A hand tool or plier including a plurality of lever arms, a number of jaws, a cam assembly and a cam follower. The plier tool provides efficient and comfortable transfer of energy from the human hand to the plier tool by utilizing an lever arm and at least part of the cam to generate a transformational increase in mechanical advantage and allow maximum amount of power to be derived from a hand squeezing action, and to do so with a minimum discomfort and strain to the hand because the strongest part of the hand squeezes the handles portions with the greatest travel.
