Abstract: A release device may include a lifting and pre-stopping element having an upper sliding surface, the part coupled to a drive such that the sliding surface is movable over the sliding plane into an enabled position and at the level of the sliding plane into a blocked position, the part having a stop which in the enabled position protrudes beyond the sliding plane. A blocking element, behind the part in the sliding direction, has an upper blocking element sliding surface, a blocking edge protruding beyond the sliding plane, and an extendable/retractable block coupled to the drive such that the block is movable below the blocking element sliding surface into an enabled position and above the blocking element sliding surface into a blocked position. The blocking edge may be in front of the block in the sliding direction, preventing contact between the piece good and the block in the blocked position.

Abstract: A product delivery device includes a receiving tray. The receiving tray includes a bottom plate, a pushing plate, and a shielding plate. The pushing plate is toward the shielding plate, and the shielding plate is rotatably attached to the bottom plate. A product exit is defined in the bottom plate and is covered by the shielding plate. The pushing plate pushes a product onto the shielding plate. The shielding plate rotates to allow the product to drop out of the receiving tray via the product exit.

Abstract: A semiconductor device includes a nitride semiconductor stack having at least two hetero junction bodies where a first nitride semiconductor layer and a second nitride semiconductor layer having a band gap wider than that of the first nitride semiconductor layer are disposed, and includes a drain electrode and, a source electrode disposed to the nitride semiconductor stack, and gate electrodes at a position put between the drain electrode and the source electrode and disposed so as to oppose them respectively in which the drain electrode and the source electrode are disposed over the surface or on the lateral side of the nitride semiconductor stack, and the gate electrode has a first gate electrode disposed in the direction of the depth of the nitride semiconductor stack and a second gate electrode disposed in the direction of the depth of the nitride semiconductor at a depth different from the first gate electrode.

Abstract: A coin drop mechanism comprises a support member movably connected to a channel member. A contoured channel configured to receive at least one coin is formed on at least one of the members and defines a coin slot when the members are in contact with each other. The channel is configured to guide the at least one coin to a desired location aligned with an actuator opening on the members. The mechanism further comprises an actuator. The actuator comprises a actuation member configured to travel through the actuator opening, engage the at least one coin against a surface of the channel member, and displace the channel member relative to the support member causing a selected product to be dispensed from a product receptacle.
