Abstract: Test apparatus (10) performs non-destructive testing of an object (O) to determine if it has flaws or defects. An ultrasonic wave (W) is generated and directed at the object. A return wave (R) reflected by the object is received and analyzed to determine if a flaw or defect. The return wave is converted to digital data which is stored for purposes of later analysis. For this purpose, digital signals containing the data are routed over a quiet bus (24). Digital signals are routed over the bus prior to generation of an ultrasonic wave to establish test parameters. Digital noise may occur during the transmission. A controller (22) controls routing of digital signals over the bus. The controller inhibits the flow of digital signals over the bus during that portion of an operational cycle of the apparatus during which the ultrasonic waves are produced and return waves evaluated. The controller allows transmission of digital signals over the bus at other times. As a result, the ultrasonic portion of the apparatus is effectively isolated from the bus so any digital noise thereon cannot effect the ultrasonic portion of the apparatus and the test results produced thereby.

Abstract: A connecting rod as a shaft clamping member includes a rod member and cap, each of which has mating faces at circumferentially opposite ends of a semi-circular recess and which are fastened to each other by bolts by matching the opposed mating faces to each other to define a crank pin hole by the two semi-circular recesses. The rod member and the cap are forgings formed from an aluminum alloy and simultaneously produced by forging powder preforms of the rod member and cap in a cavity having the desired shape of the connecting rod. After forging, the opposed mating faces have an infinite number of recesses and projections which are formed from the flow of the material during the forging and which are in a matched and fitted relation to each other. Thus, any misalignment between and in a direction parallel to the mating faces can be prevented to avoid the generation of a situation that only the rod member receives a stress. This achieves a prolongation in the life of the connecting rod of the aluminum alloy. The composition of the most desirable aluminum alloy include, by weight, 7 % ≦ Fe 15 %, 1 % Si 4 % and between 1 % and 3 % of a metal selected from Ti, Zr, Mn, Ni, Cr, V, Mg and Mm (Misch metal) with the balance Al. The preferred forging temperature is between about 550°C and 650°C.

Abstract: A sorting device with a transport device (5) for displacing objects such as, for example, postal items (99) from an input station (1) to an output position (3a, 3b) selected from among a plurality of output positions (3). The transport device (5) comprises a field (101) of individual transport units (23, 105) arranged in a hexagonal grid shape and each provided with a transport mechanism (27) arranged on a rotatable support (25). The output positions (3) are positioned alongside the field (101), while the field (101) is accessible through at least two separate input positions (9, 11, 109, 119). Alternative routes can be selected by means of an electronic control unit (15) and microprocessors (127) in the field (101) between an input position (9, 11, 109, 119) and a selected output position (3) by joining together the individual transport units (23, 105). 
     The use of at least two separate input positions (9, 11, 109, 119) and of the grid-shaped field (101) renders it possible to move several postal items simultaneously and in parallel through the field (101), so that the sorting device has a great handling capacity. 
     The sorting device is suitable for sorting of postal items which are provided with address codes corresponding to destinations of the items. During sorting of comparatively light postal items such as letters, a great capacity is provided, while a satisfactory capacity is provided during sorting of comparatively heavy postal items which are moved at comparatively low speeds through the sorting device, for example, postal parcels.

Abstract: The object of the invention is to achieve, in the case of a luminous or display unit of the generic type, over the attenuation curve of a light-guiding layer, a uniform intensity distribution of the light which emerges, through the surface, towards the front, and to show, as a result thereof, new arrangements of the light-guiding layer and novel applications. This object is essentially achieved in that a surface of at least one light-guide body is formed by the random arrangement of geometric figures as a diffusely reflecting surface, the expectation value of the ratio of reflecting surface to overall surface of a small, selected region corresponding to the attenuation curve or approximately to the attenuation curve for constant light emission and the continuous attenuation curve being approximated by a discontinuous curve, and in that, in the case of a display unit, the display symbol is arranged in a known manner. <IMAGE>

IPC: G06F15/16
Filed: 1994-09-15
Abstract: An interrupt packet protocol for both interrupt requests and interrupt resets. Address bus packets are used to signal and transfer information. When an interrupt source has an interrupt request, it requests use of the address bus. When granted the bus, the interrupt source sends out an interrupt request packet. The interrupt controller processes the information and signals an interrupt to the processor. In a multiprocessing system, the interrupt controller may route the interrupt information to an appropriate processor. When the processor is done processing the interrupt, it will alert the interrupt controller to send a reset packet to the interrupt source. 
     By sending interrupt information over the address bus, it allows for use of an underutilized resource, the address bus, and not use the busier data bus. The interrupt packets going over the address bus use the address lines already in the system at a cost of zero pins and zero wires. This is in contrast to prior methods, which used several interrupt lines. Since interrupts are transferred over the address bus, they are sequenced with other interrupts and with other system operations. This is helpful during debug because it makes interrupts more observable at a system level and less asynchronous to the system. Since interrupt information is defined in various fields in the interrupt packet instead of being hard-wired on the planar, this interrupt system is very programmable.

Abstract: A displacement converter in which a pressure difference is determined by detecting capacitances C1 and C2 between fixed electrodes (3, 4) and a diaphragm (1), which receives pressure differences on both of its sides and can be displaced. The pressure difference is output as a process-unified signal via a V/I converter (209). This eliminates the need for tedious adjustments involving hardware such as a compensation capacitor in order to compensate the floating capacitance in capacitances (C1, C2), which is unrelated to diaphragm displacement. Instead, adjustment (calibration) is simplified without decreasing measurement precision, in that a microprocessor (205), in an initial calibration mode, takes a plurality of known pressure differences and measures capacitances (C1, C2) using time constant measuring unit (202), A/D converter (203) and timer counter (206). This data, which is needed to determine the constants needed to perform correction on floating capacitance and detection of pressure, is stored in memory (204). In measurement mode, pressure difference is calculated by using the measured capacitances (C1, C2) and the constants stored in memory (204). The results are output by the converter via D/A converter (207) and V/I converter (209).

Abstract: The drain-to-source voltage and current for programming a selected nonvolatile memory cell  10  are achieved efficiently by pumping the source  11  of a selected cell  11  to a voltage less than the voltage  VSS  at the reference-voltage terminal of the memory cell array while, at the same time, pumping the drain  12  of the selected cell  10  to a voltage greater than the voltage  VCC , which may be 3V, at the supply-voltage terminal of the memory cell array. The cell substrate  W2  is pumped to a voltage close to the voltage of the source  11  and, optionally, below the voltage of the source  11 . One or more simple charge-pump circuits convert the output of the voltage supply  VCC  to a source-drain voltage and current capable of programming the selected nonvolatile cell  10  by hot carrier injection.
