Title: Accessing data from first and second DRAMs
Inventor: TILLEMAN RUSSELL
IPC: G11C11/408
Filed: 1993-08-13
Abstract: A memory control circuit is constructed so that first, second and third addresses are provided to first and second DRAMs during respective cycles 100A, 100B, 100C. A row address strobe signal is provided to both DRAMs during the first cycle, a column address strobe signal CAS-A is provided to the first DRAM during the second cycle, and a column address strobe signal CAS-B is provided to the second DRAM during the third cycle. The first address functions as a row address for both DRAMs, the second address functions as a column address for the first DRAM, and the third address functions as a column address for the second DRAM. Alternatively (Fig 5), a row address strobe signal is provided to the first DRAM during the first cycle, signal CAS-A is provided to the first DRAM during the second cycle, a row address strobe signal is provided to the second DRAM during the second cycle, and signal CAS-B is provided to the second DRAM during the third cycle. In that case the first address functions as a row address for the first DRAM, the second address functions as a column address for the first DRAM and a row address for the second DRAM, and the third address functions as a column address for the second DRAM. In either case, data can be accessed from both DRAMs in only three clock cycles. <IMAGE>

Abstract: PCT No. PCT/IB94/00259 Sec. 371 Date Feb. 20, 1996 Sec. 102(e) Date Feb. 20, 1996 PCT Filed Aug. 17, 1994 PCT Pub. No. WO95/05200 PCT Pub. Date Feb. 23, 1995A conjugate of a carrier polymer and aziridine ring containing mitomycin (MMC) drug molecules is prepared by coupling the MMC molecules via their aziridine imino groups to spacer groups that terminate in protected amino groups, deprotecting said amino groups, recovering and purifying the spacer-MMC derivatives, and then coupling these derivatives via said deprotected amino groups to the carrier polymer. Alternatively, the MMC may first be treated with an activating agent, e.g. carbodiimidazole, to form an activated MMC derivative which is then coupled directly to spacer groups linked to the carrier polymer.

Patent GB-933676-A (GB)
Abstract: 933,676. Stereophonic systems. PHILCO CORPORATION. March 13, 1962 [March 13, 1961], No. 9649/62. Class 40 (4). In a stereophonic reproducing system, Fig. 1, the two normal channel signals A and B are applied to a matrix 16 where the channel signals are summed and differenced, the sum signal is applied via an amplifier 26 to a reproducer 28 and the difference signal is amplified and applied to reproducers 36 and 38, 36 working in antiphase to reproducer 38. The resultant signal at the listener at O is shown to produce the normal two - channel stereophonic effect. Amplifier 30 however, since it is handling only the difference signal which at low frequencies is negligible, may be of a lower power handling capacity and restricted frequency range compared with the amplifier 26. In an alternative system, Fig. 3, the antiphase difference signals are produced by one double side electrostatic transducer 52 the apparent separation of the sources being achieved by reflection from the walls 62 and 64. A further alternative using two oppositelydirected electrodynamic speakers in place of the electrostatic speaker is described, Fig. 3A (not shown), and an enclosure for the speaker arrangement utilized in Fig. 3 is shown in Fig. 4, the walls of the room being replaced by baffles 86 and 88.

Title: Optical waveguide with a pig tail optical fiber
Inventor: IMOTO KATSUYUKI
IPC: G02B6/42
Filed: 1994-05-24
Abstract: An optical waveguide with a specific refractive index difference DELTA 1 has a core 63 with a rectangular cross-section in a cladding layer 3 with a lower refractive index than the core formed on a substrate. A pig tail optical fiber comprising a first fiber 2 serially connected to a second fiber 1 is connected to an input terminal of the optical waveguide. The second fiber 1 with a specific refractive index difference  DELTA 2 (< DELTA 1) is connected to a terminal of the first fiber 2 with a specific refractive index difference nearly equal to  DELTA 1. A diffusion region 4 at the neighborhood of the connection of the fibers 1, 2 is formed by diffusing dopant for refractive index control in the core of the first fiber 2 by heat. By the diffusion region, the mode field diameters of the first and second fibers are adjusted so as to have nearly equal diameter at their connection. <IMAGE>

Title: Capacitive touch detection
Inventor: FRINDLE PAUL
IPC: H03K17/96
Filed: 1994-09-15
Abstract: A capacitive touch detection system, which can be used to inhibit motorised faders in an audio mixing system, includes touch detection circuits 141 to 14n each having a respective conductive area 161 to 16n for touch determination by detection of increased capacitance at the conductive area. The touch detection circuits 141 to 14n are operable during predetermined active periods initiated by a clock generator 10 which activates a pulse generator 121 to produce an enable pulse EP1 for the detection circuit 141. The trailing edge of that enable pulse EP1 generates a non-overlapping enable pulse EP2 for the next detection circuit 142, and the process continues so that no more than one detection circuit is active at any time. This minimises interaction between detection circuits if more than one conductive area should be touched simultaneously. A touch detection circuit suitable for such a system (Figure 3) and a method of assigning the controls of a multi-channel signal mixing console to a particular channel in response to a touch sensor output are also disclosed. <IMAGE>

Title: Digital decoding of biphase-mark encoded serial digital signals
Inventor: RAINBOLT JOE L
IPC: H03M5/12
Filed: 1995-01-12
Abstract: A digital decoder for a biphase-mark encoded serial digital signal detects edges in the encoded serial digital signal by sampling with a sample clock to produce a blivet signal. The blivet signal is filtered by a one-bit digital lowpass filter (16) to recover a decoded clock signal and to generate a transition window signal. The blivet and window signals are used to detect whether there is a transition within each bit interval defined by the decoded clock signal. A decoded serial digital signal has a logical one for each bit interval in which a transition occurs, and a logical zero otherwise. <IMAGE>

Title: Low profile communications outlet
Inventor: ELISEI DAVIDE
IPC: H01R24/64
Filed: 1996-10-02
Abstract: A communications outlet (2) comprises a face-plate (4) and a connection assembly module (6). The assembly module (6) comprises an outlet connector (8) and a cable connector (10) mounted on a printed circuit board (PCB) (12). Different outlet connectors (8) and PCBs (12) can be provided whilst the design of the cable connector (10) remains unchanged. The positioning of the outlet connector and cable connector directly on the PCB (12) which is substantially parallel to the outer wall (74) of the face-plate (4) provides a low profile communications outlet. Stuffer members (56) provide rapid tool-less connection of cable conductors to insulation displacement contacts (26) of the cable connector (10). An advantageous feature is the provision of secondary locking extensions (78) on the face-plate that engage behind the resilient latches (44) of the connection assembly module for mounting of the module to a wall plate. The secondary locking extensions (78) ensure secure retention of the connection assembly to the wall plate.
