Abstract: The present invention relates to an agent which slows down the heart rate which has an excellent controlling ability in diagnostic imaging comprising a short-acting ?-blocker (e.g. landiolol hydrochloride or esmolol hydrochloride). The short-acting ?-blocker has a property of slowing down the heart rate and it can temporarily suppress the tachycardia at diagnosis. According to the dose and the method of administration, it can control the period for the heart rate adjustment. Also, the present invention relates to a diagnostic imaging auxiliary comprising a short-acting ?-blocker as active ingredient.

Abstract: A burn-in socket assembly for receiving an IC package has a base defining a cavity for receiving the IC package and a loading member retained in the cavity. The loading board has a bottom plate for loading the IC package, a plurality of positioning clumps and a plurality of positioning tabs. The bottom plate defines a plurality of passageways. The positioning clumps are assembled upon the bottom plate, and the positioning tabs detachably insert into corresponding passageways of the bottom plate from the bottom to the top to retain the positioning clump to the bottom plate. The positioning clumps cooperatively define a rectangular opening for positioning the IC package.

Abstract: A socket assembly has a socket and a heat sink module detachably mounted on the socket. The socket has a base, a sliding board mounted on the base, a lid disposed upon the base and an actuator disposed between the base and the cover. The heat sink module has a fastening frame surrounding the base, a cover pivotally assembled to an end of the fastening frame and a heat sink mounted on the cover. The cover has a latching portion which latches with a top wall of the lid when the cover rotates to a closed position. The heat sink is brought by the cover to pass an open defined on the lid and to abut against an IC package seating on the sliding board.

Abstract: An IC socket for testing an IC package is provided including a socket body (10), a press cover (14) preferably pivotally mounted to a first longitudinal end (101) of the socket body so as to be rotatable with respect to the socket body, and a press member (12) disposed between the socket body and the press cover to have an end thereof (121) essentially pivotally mounted to the press cover at a position adjacent the first longitudinal end of the socket body. Thus, by providing the mounting of the press member to the press cover at such a position, a latching member (141) detachably attached to the press cover will be less damaged in comparison with the conventional IC socket.

Abstract: The present invention relates to preventive and/or therapeutic agents for Meniere's disease, which comprise a leukotriene antagonist (such as pranlukast hydrate) as an active ingredient. Leukotriene antagonists (such as pranlukast hydrate) are effective in ameliorating various symptoms, such as hearing impairment, tinnitus, a feeling of fullness in the ear and vertigo, thus being useful as a preventive and/or therapeutic agent for Meniere's disease.

Abstract: An electrical connector electrically connecting an IC package to a printed circuited board comprises a base member (1), a cover member (2) moveably assembled over the base member, an actuator (3) driving the cover member to move over the base member and a plurality of terminals. The base member defines a plurality of receiving cavities (100) therethrough receiving terminals therein. The cover member defines pin mounting holes (200) corresponding to the receiving cavities of the base member. The base member comprises a head portion (13) and a main portion (14) and the cover member correspondingly comprises a side portion (23) and a leading portion (24) respectively. Latching devices, which are formed on the main portion and the leading portion of the base member and the cover member, each comprises a latching hole (5) and a hook (6) mating with the latching hole. Latching holes and hooks are formed on different ones of the base and the cover members.
