Abstract: A locking assembly for releasably securing an electronic module within a host instrument comprising a body portion, aligning elements for aligning the body portion relative to the host instrument and a fastening member associated with the body portion for mounting the body portion to the host instrument. The fastening member is operable to gradually urge the body portion in a direction for electrical engagement between the module and the host instrument. A latch member is mounted to the fastening member and a frictional element is disposed between the fastening member and the latch member. The frictional element frictionally engages the fastening member and the latch member is operable to cause the latch member to move with the fastening member as a result of the frictional engagement therebetween.

Abstract: In a high-voltage output buffer, a self-adjusting bias generator is provided which is capable of automatically adjusting the applied bias voltages in the output buffer so as to enhance the output buffer performance. Under normal or high supply voltage conditions, the bias generator provides a first set of bias voltages to the series-connected transistors in the output buffer. Under low supply voltage conditions, the bias generator provides a second set of bias voltages to the various series-connected transistors.

Abstract: Copper conductive foil for use in preparing printed circuit boards is electrodeposited from an electrolyte solution containing copper ions, sulphate ions and thiourea.

An IPC Class 2 foil is prepared without annealing.

Abstract: A highly stable high-voltage output buffer is provided which may be manufactured using standard CMOS technology. As part of the invention, the effects of voltage drift at one or more of the nodes formed between series connected P or N-channel MOSFET devices are generally reduced or eliminated. The present invention includes compensation circuitry which reduces the effects of parasitic coupling within the MOSFET devices, and which serves to compensate for any voltage drift which may occur at the nodes between series connected devices. In addition, the present invention provides a method and apparatus for increasing the current sourcing capability of a CMOS high-voltage output buffer, even under low supply V.sub.vf conditions, without necessarily increasing the size of the output device. Furthermore, the present invention provides a method and apparatus for reducing the effects of coupling along a shared bias line between a plurality of high-voltage output buffers in accordance with the present invention.

Abstract: A conductive copper foil for use in preparing printed circuit boards is protected from damage during storage, shipment and further processing by covering at least one side of the foil with a sheet of plastic film. The film is removably joined with the foil as a result of the essential absence of gaseous material between the film and the foil. Thus, the film conforms intimately to the contours and shape of the foil surface and clings tightly thereto to permit movement and further processing of the foil with the film adhering tightly thereto. The absence of air between the film and the foil is produced by oppositely statically electrically charging the film and the foil such that they are forced together sufficiently to squeeze the air out from therebetween.

Abstract: A conductive copper foil for use in preparing printed circuit boards is protected from damage during storage, shipment and further processing by covering one side of the foil with a sheet of polyethylene film. The film is removably joined with the foil by an adhesive material placed between the film and the foil in a marginal area of the latter. The film is selected to be sufficiently resistant to laminating temperature and pressure conditions so as to remain in its covering, protecting relationship to the foil and avoid sticking to the laminating press plate and retain its removability from the foil after lamination.

Each compartment in the tank is substantially closed at its lower end, and open at its upper end. The belt travels in and out of each of the tank compartments in sequence, being subjected to a liquid cleaning treatment in each by contacting sprays and/or bath immersion before being returned to the filter tray for reuse. A wringer is provided at the top of each compartment through which the belt passes before proceeding to the next compartment in order to isolate the treatment liquids from each other.
