Patent EP-0329570-A2 (EP)
Inventor: BLASER MARTIN J
IPC: C07K14/205
Filed: 1989-02-17
Abstract: Antigenic compositions are disclosed for use in diagnostic kits and the like for detecting the presence of antibodies specific for Campylobacter pylori, bacteria often associated with the occurrence of Type B gastritis and peptic ulcer disease. Samples of bodily fluids, for instance, may be contacted with immobilized antigen which is then washed and tested for the occurrence of significant levels of antigen/antibody complex. Levels exceeding a predetermined positive threshold are indicative of antibodies to Campylobacter pylori in the sample tested. Kits employing the antigenic compositions of the invention preferably include means for detecting the antigen/antibody complex such as materials and reagents for conducting an enzyme-linked immunosorbent assay, Western blot technique, liposome-based assay or other known detection tests.

Abstract: In an information recording and reproducing apparatus for recording or reproducing information to/from tracks by irradiating a light spot (3a) to an optical disk (100) in which N sectors are included per track and the number of necessary alternating sectors per track is set to M, the apparatus has a track format such that when a desired moving time of the light spot between the adjacent tracks is k (k > 1) times as long as a desired sector passing time of the light spot, M or more alterating sectors are arranged subsequent to the (N - M - k) ordinary sectors to record user's data. The light spot jumps between the tracks for a period of time corresponding to k sectors. Thus, the recording of information to a certain track and the subsequent reading check (Read After Write) can be effectively executed at a high speed.

IPC: H03K17/567

Abstract: An adaptive gate discharge circuit for discharging the gate of a power FET transistor. The adaptive gate discharge circuit includes discharge driver circuitry which responds to the control signal by discharging the power FET gate from the initial "on" potential of the power FET to below a selected potential at which the power FET is turned off. During gate discharge, but prior to the potential of the power FET gate dropping below the selected potential, adaptive bias circuitry continues to operate to provide biasing current both to the discharge driver circuitry as well as to any other circuitry it may be biasing. However, when the potential of the power FET gate drops below the selected potential, low current biasing circuitry reduces the operating voltage of the adaptive biasing circuitry thereby turning off the adaptive biasing circuitry and any other circuitry it may be biasing.

Abstract: The disengagement of the off-going clutch C1-C5 is monitored to determine as early as possible if there is a clutch tie-up due to failure to disengage. Beginning at the initial clutch release command, the turbine speed Nt and output speed No are used to determine if clutch slip has occurred and a pass signal is given if slip occurs in several consecutive control loops. Beginning a preset time after the command to exhaust fully the clutch C1-C5, the number of no-slip conditions are counted. A fail signal is given when a set number of no-slip conditions are counted.

Abstract: A digital signal recording/reproducing system specifically has an adaptive automatic equalizer (11, 12) for performing automatic waveform equalization disposed in a reproducing circuit of an RF system. In order to provide a run-up pattern which enables stable operation settlement of the adaptive automatic equalizer (11, 12) and a clock reproducing PLL (16) at the time of reproduction, the digital signal recording/reproducing system comprises a run-up code generator (3) for producing a run-up pattern composed of a combination of at least two digital value series of different inversion intervals. Thus, since an optimum run-up pattern for the reproducing circuit of the RF system is produced and recorded on a recording medium (7) within a fixed period at the time recording, stable settlement of the operation of the clock reproducing PLL (16) and the adaptive automatic equalizer (11, 12) is attained within a run-up period at the time of reproduction, thereby making it possible to suppress occurrence of a code error to a minimum.

Abstract: An apparatus for determining cacheable address and write-protect memory address regions in a computer system which includes a programmable single-ended limit register and a single comparator to determine each such region. A programmable limit register associated with each respective memory address region defines a boundary limit for each of the respective memory regions. A single address comparator associated with each respective limit register determines whether a memory address developed by the computer system resides between the respective boundaries provided by the value stored in the respective programmable limit register and a predefined address. The use of a single limit register and a single address comparator for each memory address region reduces the gate count and decreases the input buffer loading in the logic circuitry.
