Abstract: 1350840 Semiconductor devices TEXAS INSTRUMENTS Inc 6 July 1971 [6 July 1970] 31620/71 Heading HlK A semiconductor slice to be subdivided into individual wafers 40 is mounted, via leads attached to bonding pads, on an array of wafer receiving members 32 so that, after subdivision, e.g. by etching, each wafer 40 is attached to a corresponding member 32. The members 32 are subsequently detached from each other and from a support body 26 to produce a plurality of separate units. As disclosed each unit is a thermal print head containing, in the upper surface of the wafer 40, an array of mesa heater elements. The lower surface of each wafer 40 is provided, before bonding to the members 32, with bonding pads and attached Au leads 22, The members 32 are formed by sawing an alumina sheet stuck to a glass support body 26, and wax 34 is used to fill the slots made by the sawing process. Wax is also used as the adhesive layer 28 between the members 32 and the support body 26 to facilitate detachment of the print head units from the support body 26 after subdivision of the slice. The adhesive 36 between the slice and the members 32 may be epoxy resin. The alumina member 32 of each print head unit is mounted on an Al heat sink.

Title: Improvements in or relating to Doppler Radar Devices
Inventor: JORGENSEN TAGE
IPC: G01S13/58
Filed: 1966-07-15
Abstract: 1,198,794. Doppler radar. TERMA ELEKTRONISK INDUSTRI A/S. 5 Oct., 1967 [15 July, 1966], No. 31818/66. Heading H4D. The Specification describes a C.W. Doppler radar system for determining the speed of a missile 6 in at least two sections along its trajectory. Basically the Doppler frequency is determined, either as a known number of Doppler oscillations divided by the measured time for said number to occur (illustrated embodiment) or as the measured number of Doppler oscillations divided by the known time of said measurement. The Doppler frequency is converted into pulse form by generator 14, and the pulses fed via gate 18 (only opened, when said pulses are present, by means of detector 16), to a pulse counter 20 which has the capacity to count over all of the missiles trajectory under investigation. The count in counter 20 is proportional to the distance flown by the missile. Thus to determine the missile's speed during a first, rear, section of the trajectory, AND gates 22 and 24 are provided to respectively give an "open" pulse and a "close" pulse when the missile is at the beginning and end, respectively, of said section. The "open" and "close" pulses operate a gate 30 passing 1 Mg/s. pulses from generator 34 to counter 36. The count of counter 36 thus indicates the time for the missile to pass through said trajectory section. Gates 26 and 28 are similarly connected to later stages of the counter 20 for measurement of the missile's speed during a later section of its trajectory. "Close" gates 24, 28 may be dispensed with if the "open" pulses each start a further counter counting the Doppler pulses and said further counters produce the "close" pulses when their counts indicate the passage of the missile through the respective section. Alternatively the "open" pulses may each start a timing device and open the respective gate 30 or 32 which now counts the Doppler pulses. The timing devices produce the "close" pulses after said known time.
