Patent EP-0202962-B1 (EP)
IPC: H03K17/14
Filed: 1986-03-28
Granted: 1991-06-05
Abstract: The invention concerns a process for control of the opening of a power interrupter, especially a transistor, at a determined instant, regardless of the particular characteristics of the interrupter. According to the invention, the emission of the normal closing command (A) of the interrupter is terminated at a determined time interval before the said determined instant, and in its place is emitted an additional closing command (G) with a duration equal to the difference between the said interval and the actual time required by the interrupter to pass from the closed state to the open state. Preferably, the actual time required by the interrupter to change state is determined during its preceding passages from the closed state to the open state.

Title: Test method for detecting faulty memory cells in a programmable semiconductor device
IPC: G11C17/00
Filed: 1986-09-09
Granted: 1991-12-04
Abstract: For testing unwritten-in field programmable memory cells, some specified written-in cells have been previously provided in the semiconductor device. In the first method, while a readout circuit, which reads datum written in the memory cell, is enabled, addressing-signals selecting the memory cell are switched from the written-in cell to a unwritten-in cell to be tested. Then, the voltage of the bit line operatively connected to the selected unwritten-in cell starts to rise gradually to that of the unwritten-in cell. The delay of this rising voltage, after the moment of the address-switching, is detected by the voltage level at a predetermined time, or by the time when this rising voltage reaches a predetermined threshold level. This delay corresponds to the degradation of the cell by leakage. In the second method, while the readout circuit is disabled, the addressing signals are switched from selecting written-in cell to selecting an unwritten-in cell to be tested, and then the readout circuit is enabled. The delay of the rising bit voltage is detected in the same way as those of the first method, but the time is measured from the moment at which the "enable" signal is applied. These delays can be also detected at the output terminal of the readout circuit.

Abstract: A tool chuck for securing a tool bit in a drilling and cutting device includes a guide tube into which the tool bit is inserted and an adjusting sleeve displaceable relative to the guide tube. The guide tube has spaced first and second apertures with the first apertures holding locking members and the second apertures holding entrainment strips. The adjusting sleeve has alternating first and second pockets in its inside surface for receiving the locking members and the entrainment strips. With a tool bit having slots for both the locking members and the entrainment strip, both the locking members and entrainment strips can be displaced radially inwardly by the adjusting sleeve. If the tool bit has only slots for the locking members, the locking action can be effected with the entrainment strips maintained radially outwardly from the tool bit.

Abstract: The fixing element is comprised of a plane support, for example a network, and of hooks (1) (2) projecting from different parts of the support and connected by spring clamps (10), having a fine structure or a micro structure. The fixing element adheres to all flat material wherein the hooks may grip, such as skin, leather, rubber, soft synthetic material, cloth. It retains its adhesion properties even if the surface is greasy, dirty, wet, dusty or covered with hair or even immersed in water. An important application of the fixing element is the toupet. In the medical field, it may be used for example for fixing the electrodes in an ECG, the electric conductivity properties of the hooks providing an additional possibility.

Abstract: Packing machines which manufacture packing containers of the so-called gable-top type from flexible packing laminate frequently handle prefabricated, tubular packing container blanks which are provided with a bottom through folding in and sealing of a number of bottom wall panels. The bottom is pressed down and sealed whilst the blank is supported by a mandrel on a mandrel wheel. In order to avoid the transmission of the pressing-down and selaing forces to, and stressing of, the axle and bearing of the mandrel wheel an arrangement is proposed in accordance with the invention which is designed so that the compressive forces generated by means of the pressure devices (5) are absorbed by a tie rod (30) which connects the pressure application arrangement (14) with the axle (19) of the mandrel wheel (3), so that the forces are absorbed internally without stressing the mandrel wheel axle (19) or other surrounding elements.

Title: Method and apparatus for measuring and controlling indentation in resistance welding
IPC: B23K11/25
Filed: 1987-06-04
Granted: 1992-05-06
Abstract: Apparatus and accompanying methods for use therein for measuring and controlling weld indentation during resistance welding operations are disclosed. During a welding operation, the apparatus measures changes in a distance separating a reference point located on an electrode assembly and a region situated on the surface of the workpiece being welded wherein the region is not substantially indented by the electrode. Specifically, a distance measuring system first establishes the location of the surface relative to the electrode before any welding current is passed through the weld area. The indentation is repeatedly measured by detection of ultrasonic echoes from the surface of the material being welded. Such measurements are taken at frequent intervals during the current flow period during which the weld is being formed in order to determine on a continuous basis the indentation of the electrode into the surface. The welding power may be terminated when the measured indentation reaches the desired value. In order to obtain more precise control of the indentation, the rate at which indentation occurs can be measured and the welding power can be changed on a half cycle by half cycle basis to increase or decrease the indentation rate according to a desired indentation program.

Abstract: An electronic circuit breaker having a trip solenoid assembly. The trip solenoid assembly includes a permanent magnet (20), plunger (14), trip coil (26) and assist coil (28) and is positioned adjacent to a phase conductor. At high current levels the phase conductor generates a flux that may cause the circuit breaker to nuisance trip. An assist coil (28) is wound adjacent the trip coil (26). The assist coil (28) is energized only when the current through the circuit breaker is of such a level so as to cause nuisance tripping. The assist coil (28) is not energized during the time period when the trip coil (26) is energized.

Abstract: The hollow tack button shank (21) was connected, in particular, to a shank end (24) which widens out in a bowl shape and has to cut a hole (19) in the web (10) of carrier material during the tacking process. However, said end must be compressed on the outlet side of the web of carrier material in a deformation chamber (15) of a counter-holding part (14) during the tacking process. In this case, there was always a tendency to use one type of tack button for webs of carrier material of different thicknesses, for which reason there was a long shank. This led to difficulties during tacking and tack button shanks breaking off. The wall of the tack button shank is provided with axially extending longitudinal zones which have a different strength relative to one another in relation to the dimensional changes occurring during the tacking process. This requires crinkling. <IMAGE>

Abstract: In an eccentric disc grinder, the grinding disc unit (7), during the machining of the workpiece, preforms a movement revolving around the eccentric shaft (4) driving the grinding disc (8). In order to prevent the rotary speed of the grinding disc unit (7) from being able to increase up to the rotary speed of the eccentric shaft (4) during idling as a result of the friction occurring at the bearing (6) carrying the grinding disc unit (7), a magnetic or electro-magnetic coupling device with a coupling part (20) fixed to the housing and a coupling part (21) fixed to the grinding disc is arranged between the grinding disc unit (7) and the housing (3). The two coupling parts (20, 21) face one another in the axial direction. One of the coupling parts is a magnet part with a magnetic field extending to the other coupling part. This interacts with the other coupling part in such a way that a holding force is exerted on the coupling part (21) fixed to the grinding disc and is thus exerted on the grinding disc unit (7), which holding force is effective in the peripheral direction of the grinding disc unit (7). <IMAGE>
