Abstract: ABSTRACT:          A semiconductor device having a semiconductor layer of a first conductivity type which is situated on a substrate region of the second opposite type.  Present within an island-shaped region of the layer are a surface-adjoining active zone of the second conductivity type, for example the base zone of a bipolar transistor or the chan-nel region of a field effect transistor, and a juxtaposed highly doped contact zone of the first conductivity type. The thickness and the doping concentration of the layer are so small that the layer is depleted up to the surface at a reverse voltage across the p-n junction of the layer and the substrate region which is lower than the breakdown voltage.  According to the invention, a highly doped buried layer is present between the layer and the sub-strate region and extends at least below at a least a por-tion of the active zone, the shortest distance between the edge of the buried layer and the edge of the contact zones being at least equal to   where VB is the breakdown voltage of the p-n junction, and Ec is the critical field strength above which avalanche multiplication occurs.  As a result of this the effect of lateral current concentrations (Kirk effect) is avoided, while a high breakdown voltage is maintained.

Abstract: A LEADFRAME FOR LEADED SEMICONDUCTOR CHIP CARRIERS          Abstract of the Disclosure A leadframe with parallel side members and parallel transverse members defining chip receiving areas along the frame, has a chip pad at each area.  A support lead extends from each corner of the chip pad to corresponding conjunctions of side and transverse members.  A U-shaped support bar extends between each adjacent pair of support leads, each support bar including spaced parallel leg portions connected at inner ends to the support leads and at the outer ends by a lead support portion. Leads extend from each lead support portion towards the chip pad.  By this means the chip can be assembled to the pad and wire bonding between chip and leads carried out and the leads can be preformed or not, as desired, prior to encapsulation.  After encapsulation, the lead support portions can be trimmed off but the encapsulated device is still held in the lead frame but the leads are electrically isolated from each other.  Testing can be carried out while devices are still in the leadframe.

Abstract: ROLLER MOTION SENSING ACCUMULATOR                 ABSTRACT OF THE DISCLOSURE           This invention relates to accumulator conveyors. Druing the past two decades many types of accumulator conveyors have been developed.  These utilize a variety of different operating mechanisms and principles.  This invention is in the field of accumulator conveyors which rely upon shifting the primary propelling member vertically between a raised position in which the propelling member is in driving contact with the lower faces of the article supporting and propelling rollers and a lowered position in which it is disengaged from these rollers.  The invention is further directed to the type of accumulator in which the shift of the conveyor from conveying to accumulation mole and return to conveying mole is automatically controlled in response to the presence of the motion or lack of motion of an article on the conveyor.  Heretofore  all conveyors of this type have had some type of sensor in the form of a roller  lever wheel or pneumatic valve which is moved or triggered by an article near or over it.  It is a common characteristic of these accumulators that most of them will not close-pack the articles as they are accumulated and they have the character-istic of significantly spacing or singulating the articles as they are released from accumulation.  While these are desirable characteristics under certain circumstances  there are many applications in which the efficiency of the conveyor could be improved if these characteristics were eliminated because it would increase the throughput of the conveyor for a given length and belt speed.

Abstract: 49,224 ABSTRACT OF THE DISCLOSURE          Unitary light source comprises compact HID lamp and starting and operating circuit therefor operable from household AC energizing potential.  The HID lamp is bal-lasted by incandescent filament means which also provides the major portion of developed light during HID warm up and after power interruption.  The ballast filament and input terminals of a full-wave rectifier connect in series across the light source input terminals and the HID lamp connects  across  the  rectifier  output.   A  low-impedance path means and high-voltage pulse generator, which includes a high-voltage electrode operatively associated with the HID lamp, connect across the rectifier input.  Initially, the voltage developed across the rectifier input is rela-tively high and the pulse generator and low-impedance path means  are  responsive  thereto  to  develop  high  voltage pulses and also provide a low impedance path in series with the ballast filament to cause it to incandesce bright-ly.  The developed high voltage pulses applied to the high voltage electrode ionize the atmosphere within the HID envelope.  After the HID lamp starts,  the voltage devel-oped across the rectifier input is insufficient to ener-gize  the  low-impedance path means and pulse generating means.  As the HID lamp warms up, the brightness of the incandescent  ballast  filament means  decreases.  A  lamp keep-alive comprising a DC source is connected across the rectifier means output terminals to provide lamp operating energy during periods of rectifier conduction minima and, if necessary, to provide DC energy as a lamp starting aid.
