An ammunition cartridge assembled from (1) a substantially cylindrical polymeric cartridge casing body defining a casing headspace with an open projectile-end and an end opposing the projectile-end, wherein the casing body has (A) a substantially cylindrical injection molded polymeric bullet-end component with opposing first and second ends, the first end of which is the projectile-end of the casing body and the second end has a male or female coupling element; and (B) a cylindrical polymeric middle body component with opposing first and second ends, wherein the first end has a coupling element that is a mate for the projectile-end coupling element and joins the first end of the middle body component to the second end of the bullet-end component, and the second end is the end of the casing body opposite the projectile end and has a male or female coupling element; and (2) a cylindrical cartridge casing head-end component with an essentially closed base end with a primer hole opposite an open end with a coupling element that is a mate for the coupling element on the second end of the middle body and joins the second end of the middle body component to the open end of the head-end component; wherein the middle body component is formed from a material more ductile than the material head-end component is formed from but equal or less ductile than the material the bullet-end component is formed from. Methods for assembling ammunition cartridges and ammunition cartridges having the headspace length larger than the corresponding headspace length of the chamber of the intended weapon measured at the same basic diameter for the cartridge casing without being so large as to jam the weapon or otherwise interfere with its action are also disclosed.

A clot retrieval device comprises an elongate shaft 104 and an expandable clot retrieval element 2101 on the shaft, the clot retrieval element comprising a framework formed from a substrate material such as Nitinol and having a plurality of struts 2105 and crowns 2102, at least some of the struts 2105 comprises at least one widened portion 2104 of the substrate material to provide enhanced radiopacity. The framework is coated with a radiopaque material such as gold. The device is rendered radiopaque with reduced damping effects.

Disclosed herein is a piezoelectric type vibrator included in an implantable hearing device. The piezoelectric type vibrator comprises: a housing; a piezoelectric element portion formed at one end thereof with a free end and at the other end thereof with a non-free end, the piezoelectric element portion being at least partially disposed at the inside of the housing and including at least one piezoelectric element and terminals connected to both ends of the piezoelectric element; and a connection portion attached at one end thereof to one side of the inner wall of the housing and at the other end thereof to a non-free end of the piezoelectric element portion.

An energy conditioner structure comprising a first electrode (120), a second electrode (80), and a shield structure (70, 110, 150) provides improved energy conditioning in electrical circuits. The structures may exist as discrete components or part of an integrated circuit. The shield structure in the energy conditioner structure does not electrically connect to any circuit element.

A lid operation arrangement of a container includes an automatic operated unit for automatically operating a lid panel, a foot operated unit for manually operating the lid panel, and a motorized unit operatively linked with the automatic operated unit and the foot operated unit. When the motorized unit is activated by the automatic operated unit, the motorized unit is arranged for generating a torque enhancing force to move the lid panel from the opened position to the closed position and for generating a decelerating force to move the lid panel back to the closed position from the opened position in a hydraulic manner. After the lid panel is lifted up to the opened position by the foot operated unit, the motorized unit only generates the decelerating force to move the lid panel back to the closed position from the opened position in a hydraulic manner.

Semiconductor devices including a plurality of gate structures disposed on a semiconductor substrate are provided. Each of the gate structures includes a tunnel dielectric layer, a floating gate, an inter-gate dielectric layer, a control gate, and a mask layer. Liners cover opposing sidewalls of adjacent floating gates. Spacers are disposed on the liners, the spacers protruding from opposing sidewalls of adjacent ones of the gate structures, and a top of each of the spacers is disposed below a top of a corresponding one of the gate structures. The liners define sidewalls of respective air gaps and the spacers define tops of the respective air gaps.

A side sill garnish at the outside of a side sill of a vehicle has a garnish main body as an outer surface of the side sill garnish; and a sound absorbing member provided on the inside of the garnish main body, and has a rigid member at an outer periphery of the sound absorbing member. The rigid member is attached to the garnish main body. Preferably, the sound absorbing member is made of a foam material, and the rigid member is formed by compressing the foam material. For example, the sound absorbing member, made of a foam material, has portions for fastening the sound absorbing member to the main body using clips; and these portions are formed by compressing the foam material. In another example, the sound absorbing member has rigid members on opposite sides in the outer periphery, and the rigid members are attached to the main body.
