Assignee:

Sandia Corporation - Albuquerque NM

International Classification:

H01L 23/62

US Classification:

Abstract:

A composite transistor is disclosed for use in radiation hardening a CMOS IC formed on an SOI or bulk semiconductor substrate. The composite transistor has a circuit transistor and a blocking transistor connected in series with a common gate connection. A body terminal of the blocking transistor is connected only to a source terminal thereof, and to no other connection point. The blocking transistor acts to prevent a single-event transient (SET) occurring in the circuit transistor from being coupled outside the composite transistor. Similarly, when a SET occurs in the blocking transistor, the circuit transistor prevents the SET from being coupled outside the composite transistor. N-type and P-type composite transistors can be used for each and every transistor in the CMOS IC to radiation harden the IC, and can be used to form inverters and transmission gates which are the building blocks of CMOS ICs.

Abstract:

An apparatus for automatically making egg rolls comprises an intermittently moving transmitting device and a plurality of forming assemblies on the transmitting device. Each forming assembly includes folding devices for folding three side portions of an egg roll dough and a mold device for receiving a part of the egg roll dough and an egg roll stuffing therein. The apparatus further comprises a device for feeding the egg roll dough successively on each forming assembly, a device for supplying the egg roll stuffing on the egg roll dough, a device for actuating the folding means of the forming assembly to fold three side portions of the egg roll dough over the stuffing in the mold device to thereby form a partially folded egg roll, and a device for wrapping the partially folded egg roll to form a cylindrical egg roll product. In the supplying device, the necessary amount of the stuffing to be disposed in one egg roll product is prepared, and the stuffing is put into the mold device to deposit the stuffing and a part of the egg roll dough therein. In the wrapping device, the stuffing portion in the mold device is pushed up therefrom and is turned for wrapping the remaining side portion of the egg roll dough.

Abstract:

Fortune cookie making apparatus includes a plurality of pivotally connected carriers arranged in an endless closed loop. Each of the carriers has at least one mold for receiving dough which is fed to molds in the carriers by feeding means fixedly disposed adjacent the closed loop. Paper feeding means fixedly disposed adjacent the closed loop deposits a length of paper on the cookie in the mold, and actuating wheel means disposed along the path of travel of the carriers receives the cookie and folds the latter along two parallel fold lines. An operating wheel means is operable to receive the cookie from the actuating wheel means and effect a second fold on the cookie to thereby form a fortune cookie.
