Title: Converting digital RGB signals to luminance and colour difference signals
Inventor: NAKATA AKIRA
IPC: G09G1/28
Filed: 1988-08-30
Abstract: A video signal processor converts digital RGB colour data into digital composite video data. The processor comprises a semi-conductor memory 231, digital-to-analog converters 235, 236, 237 and 242, balanced modulators 238 and 239, and a colour burst signal generator 240 which are adapted for construction as an MOS digital integrated circuit. 3 bit RGB colour values from a data latch 227 are converted in the memory 231 into 5 bit signals, a luminance Y signal and two colour difference signals, R - Y and B - Y. The latter are modulated in the modulators 238 and 239 by phase offset sub-carrier signals from synchronisation logic 233, also used to modulate the colour burst generator 240. Digital modulated Y, R - Y and B - Y signals and burst signals are converted in converters 235, 236, 237 and 242 to analog values which are compounded in a composite circuit 241B to form a composite video signal. <IMAGE>

Title: Security fittings
Inventor: BROOKES GARY
IPC: E05B63/12
Filed: 1989-10-10
Abstract: The security fitting for a window has a fastening assembly 1 and a keep plate 2, respectively mounted on the fixed frame 3 and moving frame 7. The assembly 1 comprises a body 6 bearing a rotatable shaft 11 with a cross-pin 13 at one end. An actuating button 15 borne slidably in the body 6 surrounds the shaft 11 and is pressed by a spring 19 against the pin 13. The spring 19 also applies a torsional bias to the shaft 11 but the shaft is held against the bias in the unfastened condition (Fig. 2), by the pin 13 lying in a slot 17 in the button 15. When the window is closed the keep plate 2 comes up against the button 15 and presses the latter into a well 16 in the body 6, thereby releasing the shaft 13 to turn under the bias of the spring 19 into a position in which the pin 13 lies in a recess 25 and cannot be withdrawn from the keep plate (Fig. 3). Unfastening is achieved by a key (29, Figure 7) engaging the head 12 of the shaft to turn back the pin 13, the compressed spring 19 acting through the button 15 to assist opening of the window. <IMAGE>

Title: Telephone answering machine has button operated playback of recorded messages
Inventor: KASHIMOTO KAZUO
IPC: H04M1/65
Filed: 1989-11-24
Abstract: Dozens of incoming messages received from calling parties are recorded on an incoming message tape and the device is then returned to a standby mode. If a user wants to play back the incoming messages properly, he can play back the desired message from its starting position by operating a predetermined button. For example, the second-to-last message is played back by operating the button twice, or the third-to-last message is played back by operating the button three times. The conventional troublesome operations of rewinding the tape each time to its beginning position or to a reasonably guessed position can thereby be eliminated. <IMAGE>

Title: Process for reducing program disturbance in EEPROM arrays
Inventor: TZENG JYH-CHERNG J
IPC: G11C16/04
Filed: 1990-05-29
Abstract: A method by which the gate oxide in an EEPROM device is selectively thickened 31 over the channel region nearest to the drain 37 so as to penalize erase-type behavior during programming of a selected cell. First the lattice structure in a portion of the channel near said drain region is intentionally damaged to enhance subsequent thermal oxidation therein and then the channel is thermally oxidized to form the tunnel oxide for the device. Due to the damage inflicted in the portion of the channel near the drain, the tunnel oxide 31 over the damaged region is thicker relative to the other portion of the channel. Alternatively oxide (41, Fig 7) is formed near the drain and then the structure is oxidized to produce oxide layer 30, 31. The thicker gate oxide near the drain thwarts drain disturbance in adjacent memory cells while speeding up source erase performance. The device is programmed by hot-electron injection near the drain and erased by Fowler-Nordheim tunnelling near the source. <IMAGE>

Title: Electrical interconnection substrate with both wire bond and solder contacts, and fabrication method.
Inventor: TRASK PHILIP A
IPC: B23K1/00
Filed: 1993-06-22
Abstract: An electrical interconnection substrate (20) is prepared to receive both wire bonded and soldered connections (60, 64, 66) by forming a dielectric solder mask (30) over the substrate (20), with openings in the mask to expose the contact pads (22) for which soldered connections are desired. The substrate (20) is exposed to a molten solder alloy in a wave soldering process that dissolves the wire bonding material (28) (preferably gold) from the exposed pads (22) and deposits solder bonding pads (52) in its place. Excess solder is then removed from the substrate, and openings are formed through the solder mask (30) to expose the wire bond contact pads (22'). The selective dissolving of gold bonding layers (29) and their replacement by solder pads (52) prevents the establishment of brittle gold-solder intermetallics, and the deposited solder (52) requires no further heat treatment for correct alloy formation. <IMAGE>
