  • Publication number: 20150099346
    Abstract: In a wafer processing method, the back side of the wafer is ground to reduce the thickness of the wafer to a predetermined thickness. A modified layer is formed by applying a laser beam to the wafer from the back side of the wafer along each division line with the focal point of the laser beam set inside the wafer. The wafer is mounted on a reinforcing sheet having an insulating function on the back side of the wafer and a dicing tape is attached to the reinforcing sheet. The peripheral portion of the dicing tape is supported by an annular frame. The wafer is heated, which also heats the reinforcing sheet, thereby hardening the reinforcing sheet. An external force is applied to the wafer to divide the wafer into individual devices along each division line and to also break the reinforcing sheet along the individual devices.

Provided in a spacing to the plug board are a first type of contact mounts for receiving plug pins of the first standard, and a second type of contact mounts for receiving plug pins of the second standard. Provided between the contact mounts and the plug board are protection elements which are movable out of a closed position in which the first and second plug-in openings are blocked, into an open position in which the plug-in openings are open. The protection elements are pretensioned into their respective closed positions by spring elements. The first and second protection elements are pretensioned into their respective end positions in different directions of movement by the spring elements.

    Abstract: A plug structure for connecting sockets comprises at least one jack formed at a side of a first socket; and a plug rod disposed on a second socket corresponding to the at least one jack and configured to plug in the at least one jack. The plug rod is electrically contacted with a spring piece in the jack so as to electrify the second socket. A slidable baffle plate is disposed on an inner side of the at least one jack and is configured to cover the jack. A through hole corresponding to the jack is formed in the baffle plate. A slope configured to push the baffle plate is disposed at a position on the baffle plate corresponding to the jack, and is disposed at an edge of the through hole and fitted with the plug rod to push the baffle plate to be inserted into the through hole. The plug structure for connecting sockets according to the present disclosure provides an improvement for a security protection of combined interfaces of the sockets, thus ensuring a security of the combined sockets.

    Abstract: A grounding member (20) is formed with a receiving hole (23), and a ground terminal fitting (10) is formed with a cantilevered lock (13) including a step (13B). The lock (13) is locked to the receiving hole (23) with the step (13B) contact with a stopper (24) of the receiving hole (23). In tightening a first bolt (51) at a first mounting hole (151) and a first female screw hole (51), a rotational force in a direction to bring the step (13B) into contact with the stopper (24) is applied to a terminal main body (11). Butting portions (14) protrude from side edges (13D) of the lock (13) and prevent following rotation of the terminal main body (11) by contacting receiving surfaces (25) when the first bolt (51) is tightened.
