    摘要: A controller IC adjusts the on time and cycle time of current flowing through the primary inductor of a flyback converter to generate a constant output current and constant output voltage. A desired output current limit is achieved even with an inductor whose inductance varies from the stated magnitude. A transconductance current is generated from a voltage across an emitter resistor and is then integrated to generate an integrated-current voltage. An inductor switch is turned on by an oscillator signal and turned off at the earlier of when the integrated-current voltage reaches a charge limit voltage during constant current mode or when the emitter resistor voltage reaches an error voltage during constant voltage mode. Current is output independently of the primary inductance by varying the current limit voltage inversely proportionally to the input voltage and by adjusting the cycle time so that it varies inversely proportionally to the output voltage.

    摘要: A disk drive head stack assembly includes an actuator arm tip that includes a swaging hole centered about a swaging axis. A first suspension assembly has a first swage boss that protrudes into the swaging hole. A second suspension assembly has a second swage boss that protrudes into the swaging hole and does not contact the first swage boss. Each of the first and second swage bosses includes an inner lip that extends radially closer to the swaging axis than any other part of that swage boss. The inner lip thickness of the first swage boss, measured parallel to the swaging axis, increases more greatly with increasing radial distance from the swaging axis than does the inner lip thickness of the second swage boss.

    摘要: In one embodiment, a code server and edit server are provided. The code server stores the source code. Users do not access the code server directly. Rather, an edit server is used where users can log in to the edit server and send requests to edit portions of the source code. The edit server then sends requests to the code server for requested portions of the source code. Different users may have different access-rights to portions of the code. When the request is received from the edit server, if the code server determines the user requesting the portion of the source code does not have access rights to it, then the code server does not allow the portion of code to be accessed. However, if the user does have access rights, then the portion of the source code is retrieved and sent to the edit server. The user can then edit the source code on the edit server.

    摘要: A protective device (10) for protecting thermal interface material (30) spread on a central surface (512) of a bottom of a base (51) of a heat sink (50). The device includes a case (12) and a tab (18) extending from an edge of the case. The heat sink (50) has air channels (552) extending vertically therethrough and around the base. The case comprises an annular frame (120) and a cap (15) protruding downwardly from inside edges of the frame. The cap covers the thermal interface material. The frame is attached to the heat sink around the thermal interface material. The frame blocks portions of the air channels adjacent to the base, thereby to prevent dust or foreign particles from contaminating the thermal interface material through the air channels.
