Patent EP-0281229-A2 (EP)
Inventor: MUMFORD RONALD WALTER JOHN
IPC: H04N3/36
Filed: 1988-01-21
Abstract: In a method of converting on optical signal into an electronic video signal by means of cathode ray tube ('CRT') scanning means (42), each image is scanned in a plurality of scanning operations with each scanning operation using a different area (32,34) of the screen of the CRT scanning means and the signals resulting from the plurality of scanning operations are combined to provide the electronic video signal. Light from the CRT scanning means is passed through deflection means (48) operable to deflect light from respective ones of the plurality of different areas (32,34) of the screen of the CRT scanning means (42) along the same path into an objective lens so that the same area of a film gate positioned in the optical path beyond the objective lens is scanned in each scanning operation. The output of the CRT scanning means (42) is monitored by means of a photoelectric device operable to provide an output signal when a blemish is detected on the screen of the CRT scanning means. The output signal is applied to an analogue-to-digital converter used to process the electronic video signal to cause the video signal level immediately prior to detection of the blemish to be maintained while the blemish persists.

Abstract: A process for the production of a physiologically active peptide (a target peptide) containing cysteine residue, comprising the steps of:
     (1) culturing  Escherichia   coli  transformed with a plasmid capable of expressing a fusion protein under control of a promoter of  E.   coli  origin or a promoter of a phage origin, wherein the fusion protein is represented by the following formula: 
      A - L - B 
wherein B represents a target peptide containing cysteine residue; A represents a partner polypeptide consisting of 90 to 220 amino acid residue but not containing cysteine residue; and L represents a linker amino acid residue positioned between C-terminal of the partner polypeptide and N-terminal of the target peptide wherein the same amino acid as the linker amino acid is not present in the target peptide, and the linker amino acid is selected so that the peptide bond between the C-terminal of the linker amino acid and the N-terminal of the target peptide is claimed by a protease or the linker amino acid is selectively degraded by a chemical substance;   (2) disrupting the cultured cells and obtain­ing an insoluble fraction containing the fusion protein;   (3) solubilizing the fusion protein with a solubilizing agent, and treating the solubilized fusion protein with the protease or the chemical substance to liberate the target peptide, and isolating the target peptide.

Abstract: In a data processing system, an instruction is disclosed that generates a fault when a predetermined register position (e.g., the low or least significant bit position) has a predetermined logic signal (e.g., a logic '0' signal). This instruction provides a mechanism to determine when a Boolean value indicates a presence of a fault condition and provides a mechanism to generate the fault when present. For example, in arrays of memory locations that can be addressed by a program, this instruction can respond to the presence of an array address (or reference) that is outside the prescribed bounds of the array. When an invalid address is identified, a signal is entered in the low (i.e., least significant) bit position of a processor scalar register. The instruction repertoire includes a Fault on Low Bit Clear instruction that tests the contents of the scalar register low bit position, and when a logic '0' signal is found therein, an exception signal is generated and applied to the control program of the data processing system.

Abstract: A suspended element (12) etched in a silicon substrate (28) which is deflected in linear proportion to an applied force. A pair of flexing means (16,18,20,22,­24,26) symmetrically positioned around the suspended element (12) provides rectilinear movement of the suspended element in response to the applied force. In one embodiment of the invention, the flexing means is formed in a single etchant step by concurrently etching nearly identical recesses (66,68,74,76) into opposing planar surfaces of the silicon substrate (28). In this embodiment, the portions of silicon remaining between the recesses and planar surfaces define the flexing means.

Abstract: The invention relates to a combined safety helmet and breathing apparatus and recognises the inherent problem with all such prior art combinations, that the wearer is totally dependent on the breathing apparatus for breathable air for the whole of the time the helmet is in use. 
     The present invention proposes overcoming this problem by providing an air passage (29, or 48) which, when open, connects the breathable volume in the helmet with the surrounding atmosphere and which air passage (29, or 48)is closeable by a valve member (30, or 49) to prevent contamination of the breathable volume by the surrounding atmosphere via the said air passage (29, or 48) when the breathing apparatus is in use. 
     The air passage (29, or 48) and its associated valve member (30, or 49) may be independent of, or incorporated into, the exhalation valve (41 to 47) for venting spent air to the surrounding atmosphere when the breathing apparatus is in use.

Abstract: A synchronous output pulse of defined length is to be provided for an asynchronous digital signal of arbitrary length, maintaining high noise immunity with respect to metastable states. The asynchronous digital signal (IN) controls an alerting flip-flop (KO) which is connected to two series-connected synchronising flip-flops (K1, K2) which are controlled by clocks (CK1, CK2) which are phase-shifted with respect to one another in such a manner that a noise-free synchronous output pulse (OUT) of defined length is emitted within a predetermined time window. A special field of application is the synchronous transfer of asynchronously occurring data signals in processing units. <IMAGE>

Abstract: An output controller in a repeater node for controlling data transfers in a data communication system in which each node is operated by an independent local clock. Nodes will occasionally delete idle bytes from a preamble to recenter an elasticity buffer. The output controller performs a process that requires the elasticity buffer to be progressively more full before deleting another idle byte from the preamble. Tranmission of the start of a subsequent frame is delayed and additional idle bytes are transmitted when the number of idle bytes being transmitted is at or below a certain threshold. Multiple thresholds are uti­lized so that the amount of the delay can be adjusted.

Abstract: The mask(3) and the wafer (4) are closely disposed, and predetermined exposure energy is applied to the respective shot areas of the wafer(4) through the mask (3). The exposure energy is soft-X-ray source, for example. The pattern of the mask (3) is transferred onto the respective shot areas in a step-and-repeat manner. In the apparatus (fig 1), a temperature control medium liquid is supplied into the wafer chuck (5) for supporting the wafer (4) at the exposure position. The flow rate is different during the exposure operation than during the non-­exposure-operation. The flow control (10) is determined in consideration of the wafer chuck vibration attributable to the supply of the liquid medium and also to the heat generation in the wafer(4) by the exposure energy, so that the vibration of the wafer chuck (5) during the exposure operation is suppressed, and simultaneously, the temperature rise of the wafer (4) can be also suppressed. The pattern transfer from the mask (3) to the wafer (4) can be precisely performed.

This arrangement overcomes problems of incorrect focusing or tracking servo operation arising from the astigmatic difference effect characteristic of the semiconductor laser unit (3).
