An ambidextrously operated bolt catch assembly for a firearm facilitates ease of use by either right handed or left handed shooters. The ambidextrous bolt catch assembly includes two levers, one on each side of the firearm, that interact with each other. Each lever has a primary contact surface and a secondary contact surface. By depressing the primary contact surface of either lever, both levers rotate to move the bolt catch assembly from a displaced position to a static position. Conversely, by depressing the secondary contact surface of either lever, both levers rotate to move the bolt catch assembly from a static position to a displaced position.

A structure comprises a high thermally conductive case with a receiver space for a power module, a thermally conductive part being provided on the case to contact a heating component of the power module in the power supply to induct the heat by the heating component to the case and contact the exterior air through the outside surface of case to dissipate the heat; and a housing the inner surface of which directly contact and cover the outside of high thermally conductive case, a grid-formed structure being formed at most of the region of housing to prevent the heat from scalding the person who touches or takes the power supply. With the large heat dissipation area, the heat is transferred through the external air to increase the efficiency of heat dissipation, and further all power parts may operate in a lower temperature to increase the work efficiency of power supply.

A piezoelectric device is manufactured in which the material of a supporting substrate can be selected from various alternative materials. Ions are implanted into a piezoelectric substrate to form an ion-implanted portion. A temporary supporting substrate is formed on the ion-implanted surface of the piezoelectric substrate. The temporary supporting substrate includes a layer to be etched and a temporary substrate. The piezoelectric substrate is then heated to be divided at the ion-implanted portion to form a piezoelectric thin film. A supporting substrate is then formed on the piezoelectric thin film. The supporting substrate includes a dielectric film and a base substrate. The temporary supporting substrate is made of a material that produces a thermal stress at the interface between the temporary supporting substrate and the piezoelectric thin film less than the thermal stress at the interface between the supporting substrate and the piezoelectric thin film.

The anode includes an anode current collector foil and anode materials, where both edges do not have an anode mixture.

The invention is a novel compact robotic manipulator with a special configuration that supports a remote center-of-motion attribute, so it has the ability to accurately and conveniently manipulate and re-orient in 2 degrees of freedom, and to firmly “lock” in place, special purpose surgical tools necessary for minimally invasive therapy. The new features include a sophisticated joint-link structure and configuration that comprises two arcuate links that enable comfortable maneuverability of the end effector or the tool about a pivot point, typically the port of entry of the tool to the patient's body, while preventing the enlargement of the key hole, in the constrained and limited workspace of surgical environments. Also the configuration of the joints provides an open structure that keeps the robots' main parts out of the surgeon's field of view and out of the work area, providing sufficient space in the vicinity of the operative field, or the entry port of the tool to the patient's internal organs. The manipulator can be used in manual, autonomous or remote-control modes.
