Abstract: A method of developing an article with enhanced reliability without unnecessarily reducing performance or increasing costs. A reliability value is allocated to each failure mode. For at least one of the failure modes, an estimated third population is derived from the estimated perforamnce and capability populations from which the number of tests required to verify the allocated reliability value is determined. If the required number of tests is greater than feasible, the design is re-estimated for the failure mode and the process repeated until the required number of tests is satisfactory. The articles are then built and tested and actual reliability values are obtained which are compared with the allocated reliability values. A decision is made to accept the design or to increase the number of tests to obtain an actual reliability value which is equal to the allocated reliability value or to re-allocate a different reliability value to the failure mode in accordance with the actual reliability value or to re-estimate the design for the failure mode and repeat the process.

Abstract: The copying apparatus has a copy-glass (2) for supporting the document to be copied, which is arranged freely accessible at a side surface to form a bearing edge (12). The page surface is arranged perpendicular to the support surface. The thickness of the copy-glass (2) is chosen such that a stage for bearing the fold region of a bound copy is formed in the region of the bearing edge (12). The copy-glass (2) is secured by two retaining and guiding rails (13), which simultaneously form the guide for a slide (17) by means of which, in particular when copying from bound copies, the region of the copy-glass (2) not covered by the copy is covered. The free region then still remaining between the bearing edge (12), the slide (17) and the copy can be put out of operation at a control panel (21) via which discharge lamps can be driven. <IMAGE>

Abstract: A power DMOST driver employs a diff-amp gate driver (14) that operates at a relatively low quiescent current when the DMOST (13) is on. Means are included for switching the DMOST (13) off and on in response to a control signal. When the DMOST (13) is to be switched from off to on the diff-amp tail current (I₁) is briefly raised to a substantially higher value so that the DMOST parasitic gate capacitance (21,22) can quickly be driven to the on level. The tail current differential is large and determined by geometrically controlled IC quantities.

Abstract: Method and apparatus which utilize an LCD modulator array for printing and/or enlarging an image recorded in a color film negative, a positive transparency or a color print, which LCD modulator array has pixels whose "closing time" (the time it takes to convert a pixel from a condition wherein it transmits radiation to a condition wherein it blocks radiation) is substantially longer than their "opening time" (the time it takes to convert a pixel from a condition wherein it blocks radiation to a condition wherein it transmits radiation). In accordance with the present invention, each pixel of the LCD modulator array is opened and closed in a rapid sequence, one after the other, at intervals which are much shorter than the closing time of the pixels of the LCD modulator array. The amount of radiation transmitted by each rapidly opened pixel is determined by detecting a spike of radiation which is transmitted through the rapidly opened pixel and by detecting and subtracting a background amount produced by radiation which is transmitted through other, slowly closing pixels.

Abstract: A method is specified for the continuous marking of electrical wires, by means of which method annular features, limited in the axial direction, are applied to the surface of the wires by means of ink jets. The ink jets emerge under pressure from at least one nozzle driven by an electrical oscillating system, whose frequency is controlled in proportion to the withdrawal rate of the wire. In order simply to change the axial distance between the features, square wave pulses are supplied to the oscillating system from a converter which converts an electrical DC voltage into a frequency, by means of which the frequency of the oscillating system is predetermined. A DC voltage, proportional to the withdrawal rate of the wire, is passed to the converter as the nominal value.

Abstract: In an MRI system, an RF field and slicing, phase encoding, and read-out gradient fields are applied to an object to be examined which is placed in a homogeneous static field in a predetermined sequence. An MR signal from a region of interest in the object is received through a probe, and is detected by a detection circuit using a predetermined reference wave. A detection output from the synchronous detection circuit is sampled to acquire MR signal data and to obtain diagnostic data. The system includes a reference wave control section (29, 30, 31, 32, 33) for shifting the frequency and phase of the reference wave, by predetermined amounts, from the frequency and phase of an MR signal when the phase encoding and read-out gradient fields are zero. The reference wave control section (29, 30, 31, 32, 33) changes a frequency shift value of the reference wave to positive and negative phases in synchronism with switching of the gradient fields, and changes a phase shift value of the reference wave stepwise.

The communications package appears to the IMS transaction manager to be an associated resource manager, and it participates in 2-phase commit procedures involving both the IMS transaction manager and the DB2 database manager. The communications package receives copies of update statements applied to the DB2 database manager, and transmits them off-site before the updates are committed to the database. 
     The communications package 25 may be used in a contingency arrangement in which a second IMS transaction manager 49 and a second DB2 database manager 51 maintain copies at a back-up site 13 of the databases at the main site 11. The update statements are transmitted by the communications package 25 to a tracking program 29, which logs them in a log 37. The logged update statements are used by an apply program 45 to update the copy databases.

Abstract: In a nonvolatile semiconductor memory apparatus of a reference type comprising a memory circuit (1), reference circuit (4) and differential amplifier (3), a drain current of a reference cell transistor (41) is formed such that it becomes almost half a drain current of a memory cell transistor (15), thereby enabling the memory circuit (1) to be in symmetric relation with the reference circuit (4). Therefore, a parastic capacitance in the memory circuit is made to be almost the same as that of the reference circuit, and thus a difference in noise level between a noise input to one input (+) of the differential amplifier (3) and a noise input to the other input (-) of the differential amplifier is made to be almost zero, thereby speeding up the data read-out operation of the semiconductor memory apparatus.

Abstract: In a mobile radio system with a central station and with fixed stations, in which the fixed stations (FS1 to FSn) transmit radio signals to and receive radio signals from mobile subscribers (MS), according to the invention, the radio signals are not generated or processed in the usual manner in the fixed stations, but rather in the central station (1). The central station (1) therefore contains a microwave transceiver (SE1 to SEn) for each fixed station (FS1 to FSn), which converts the signals to be transmitted to the fixed stations into radio signals and converts the radio signals received from the fixed stations to the baseband level. This offers the advantage that carrier frequency devices can be used collectively for a multiplicity of fixed stations, thus reducing the cost of the system. <IMAGE>

Abstract: A mirror-following imaging method is for reflecting against a rotary mirror lights from an object to be inspected being carried by conveying means to be incident on imaging means so as to make an image of the object in a frame. The mirror-following imaging method comprises the steps of detecting a positional deflection amount of the image of the object in the frame by the imaging means, anticipating a position for the object to be next imaged at, based on the detected positional deflection amount and a conveying speed of the conveying means, and rotating the mirror corresponding to the anticipated position. The mirror-following imaging method enables the object to be inspected to be correctly followed by the mirror.
