A fixture attached to the rear of the base plate of a semi-automatic screen printer includes an element holder having a vertical recess or pocket for receiving an assembly, such as a substrate, of LTCC laminate material lengthwise therein so as to expose only one side surface to the printing head which would otherwise be prevented because of the height restrictions imposed by the printer head.

A PCI to SCSI host adapter circuit is provided for use with different types of host platforms. The host adapter includes logic and controller circuits, and a memory having multiple drivers and a bank switching instruction set stored therein. During initialization, the first driver is loaded into the host's memory if the host's processor is of a compatible type. Otherwise, the bank switching instruction set is loaded into the host's memory and interpreted by the host's processor. During interpretation, the bank switching instruction set causes the host's processor to signal the logic circuit to request that the controller circuit re-map another driver to the location of the first driver in the memory. After this bank switching has occurred, the selected driver is loaded into the host's memory, provided of course that the host's processor is of a compatible type. This process may be repeated until the appropriate code type is found or the host processor is not supported.

An apparatus for jumping and charging a remote battery. The apparatus includes a charger, positive and negative charge connectors operable to be connected to the remote battery, an auxiliary battery having positive and negative terminals, and positive and negative jumper connectors separate from the positive and negative charge connectors. The positive and negative jumper connectors are connected to the positive and negative terminals of the auxiliary battery and are operable to be connected to the remote battery. The apparatus further includes a selector responsive to connecting the positive and negative charge connectors to the remote battery and operable to connect the charger to the auxiliary battery when the charge connectors are not connected to the remote battery and to connect the charger to the positive and negative charge connectors to charge the remote battery when the positive and negative charge connectors are connected to the remote battery.

A rotary switch for an electrical appliance includes a housing adapted to receive a plurality of conductive wires, a plurality of conductive terminals fixedly mounted onto the housing, an actuation shaft rotatably mounted onto the housing, and a movable contact mounted onto the actuation shaft for selectively connecting two of the conductive terminals. The housing includes a base and a cover mounted onto the base. The cover includes a top surface, a bottom surface and a plurality of inwardly tapered guide walls. Each guide wall is shaped to define a slot into which an associated conductive wire can be securely retained in electrical isolation from the remainder of conductive wires. Each guide wall has a funnel-type configuration and includes a closed end and an open end, the slot being narrower at the closed end than at the open end.
