Abstract:
A hinge used for being installed on a door and window leaf and a door and window frame (7). The hinge comprises a gear and rack unit and an inclined draw bar (1). The gear and rack unit is installed on the door and window frame (7). A gear (5) is rotatably installed on the door and window frame (7). A rack is located on one side of the gear (5). The gear (5) is meshed with the rack. A gear installation portion (51) is arranged on one side of the gear (5). The two ends of the inclined draw bar (1) are installed on the door and window leaf and the door and window frame (7) respectively. The door and window leaf can be smoothly opened and closed on the door and window frame by means of the gear and rack unit on the premise that the number of hinge parts is reduced, and the gear and rack unit can form a force arm outside the gear installation portion. The weight of the door and window is partially borne by the gear installation portion, most of the gravity of the door and window can be counteracted by the force arm formed by the gear and rack unit, and therefore the weight of the door and window can be largely shared; in this manner, the problem that the existing hinge is unreasonably stressed and prone to damage is effectively solved.

A hinge used for being installed between a door leaf and a door frame or between a sash and a window frame, (7). The hinge comprises a gear and rack unit and an inclined draw bar (1). The gear and rack unit is installed on the door frame or window frame (7). A gear (5) is rotatably installed on the door frame or window frame (7). A rack is located on one side of the gear (5). The gear (5) is meshed with the rack. A gear installation portion (51) is arranged on one side of the gear (5). Both ends of the inclined draw bar (1) are installed on the door leaf and door frame or the sash and window frame (7) respectively. The gear and rack unit not only can achieve the smooth opening and closing of sash or door leaf on the door frame or window frame on the premise that the number of hinge parts is reduced, but the gear and rack unit can also form a force arm outside the gear installation portion. In addition to the fact that the weight of the door or window is partially borne by the gear installation portion, most of the gravity of the door or window can be counteracted by the force arm formed by the gear and rack unit, and therefore the weight of the door or window can be largely shared; in this manner, the problem that the existing hinge is unreasonably stressed and prone to damage is effectively solved.

Abstract:
UNA BISAGRA QUE SE UTILIZA PARA SER INSTALADA ENTRE UNA HOJA DE PUERTA Y UN MARCO DE PUERTA O ENTRE UNA HOJA DE VENTANA Y UN MARCO DE VENTANA (7). LA BISAGRA COMPRENDE UNA UNIDAD DE ENGRANAJE Y CREMALLERA Y UNA BARRA DE TRACCIÓN INCLINADA (1). LA UNIDAD DE ENGRANAJE Y CREMALLERA ESTÁ INSTALADA EN EL MARCO DE LA PUERTA O EN EL MARCO DE LA VENTANA (7). UN ENGRANAJE (5) ESTÁ INSTALADO DE FORMA GIRATORIA EN EL MARCO DE PUERTA O MARCO DE VENTANA (7). UNA CREMALLERA ESTÁ SITUADA EN UN LADO DEL ENGRANAJE (5). EL ENGRANAJE (5) ESTÁ ENGRANADO CON LA CREMALLERA. UNA PORCIÓN DE LA INSTALACIÓN DEL ENGRANAJE (51) SE DISPONE EN UN LADO DEL ENGRANAJE (5). AMBOS EXTREMOS DE LA BARRA DE TRACCIÓN INCLINADA (1) ESTÁN INSTALADOS EN LA HOJA DE PUERTA Y EN EL MARCO DE PUERTA O EN LA HOJA DE VENTANA Y EL MARCO DE VENTANA (7) RESPECTIVAMENTE. LA UNIDAD DE ENGRANAJE Y CREMALLERA NO SOLO PUEDE LOGRAR LA SUAVE APERTURA Y CIERRE DE LA HOJA DE VENTANA A LA HOJA DE PUERTA, EN EL MARCO DE LA PUERTA A EN EL MARCO DE LA VENTANA, SOBRE LA PREMISA DE QUE EL NUMERO DE PARTES DE LA BISAGRA SE REDUCE, PERO LA UNIDAD DE ENGRANAJE Y CREMALLERA TAMBIÉN PUEDE FORMAR UN BRAZO DE FUERZA, FUERA DE LA PORCIÓN DE LA INSTALACIÓN DEL ENGRANAJE. ADEMÁS DEL HECHO DE QUE EL PESO DE LA PUERTA O LA VENTANA ESTÁ PARCIALMENTE SOPORTADO POR PORCIÓN DE LA INSTALACIÓN DEL ENGRANAJE, LA MAYOR PARTE DE LA GRAVEDAD DE LA PUERTA O LA VENTANA PUEDE SER CONTRARRESTADA POR EL BRAZO DE FUERZA, FORMADO POR LA UNIDAD DE ENGRANAJE Y CREMALLERA, Y, POR LO TANTO, EL PESO DE LA PUERTA O LA VENTANA PUEDE SER AMPLIAMENTE COMPARTIDO: DE ESTA MANERA, SE RESUELVE EFICAZMENTE EL PROBLEMA DE QUE LA BISAGRA EXISTENTE SE VEA EXCESIVAMENTE PRESIONADA Y PROPENSA AL DAÑO.

Abstract:
A semiconductor device mountable to a substrate is provided. The device includes a semiconductor die and an electrically conductive attachment region having a first attachment surface and a second attachment surface. The first attachment surface is arranged for electrical communication with the semiconductor die. An interlayer material is formed on the second attachment surface of the electrically conductive attachment region. The interlayer material is a thermally conductive, dielectric material. A housing at least in part encloses the semiconductor die and the interlayer material.
Abstract:
A semiconductor device mountable to a substrate includes a semiconductor die and an electrically conductive lead frame having first and second end portions and a first attachment surface and a second attachment surface. The die electrically contacts the first end portion of the lead frame on the first attachment surface. An externally exposed housing encloses the semiconductor die and the first end portion of the lead frame, said housing including a metallic plate facing the second attachment surface of the lead frame.
