Title: Semiconductor testing system for semiconductor integrated circuits logically linked with CAD data from CAD computer
Inventor: KOMOTO YOSHIO
IPC: G01R31/28
Filed: 1997-01-09
Abstract: The system applies test signals at the semiconducting system e.g. an IC system for each reference period and compares the resulting output signal from the system under test with the expected data. It includes a unit, to extract from the CAD design data, information across predetermined connections of the system to be tested, also waveform alterations in a test vector, which is applied at the system under test. The data are obtained indicating the connections, indicating the waveform alteration, and the time of the waveform alteration. An event store (42) stores event data indicating the presence of waveform alterations. A delay data storage (44), indicates the time, when the waveform alteration occurs, which is expressed as a time difference compared to the reference period. A waveform store (40) indicates a waveform change. A time delay circuit (44) adds the delay time to produce an output signal, which based on the delay data, read out from the delay data storage, is read out from the event storage with the reference period.
Patent DE-19704155-A1 (DE)
Inventor: KILZER JOHANN
IPC: H01R4/24
Filed: 1997-02-04
Abstract: The invention relates to a housing for an electrical connector and to an electrical connector with a housing. The housing (1) consists of an insulating material. It is suitable for receiving a metallic contact element (16). The contact element (16) has a crimping contact region for the contact-making of a first cable end and an insulation-piercing terminal contact region for the contact-making of a second cable. The intention is to avoid cables penetrating inadvertently into the insulation-piercing terminal contact region. This may be effected, for example, by a cover, the installation of which can usually be performed, however, either manually or only with a very complicated tool. The problem is solved by a housing (1) with a top wall (6) which is divided into two parts by a slit (7). The slit (7) is in this case advantageously not of a straight design, but has portions staggered with respect to one another. The side walls (5, 11) are designed in such a way that they can be bent open and then a cable (30) can be introduced through the widened slit (7) of the top wall (6) into the insulation-piercing terminal contact region (18).

Title: Connecting process for two containers one behind other
Inventor: NEUFINGERL HORST
IPC: B60P7/13
Filed: 1997-03-10
Abstract: The connecting process links two containers (10, 12) on a mobile platform. The containers have hollow corner fittings (14), the lower of which are fixed to the platform by locking elements (24). The process involves removing the locking elements from the facing ends of the containers. The rear movable part (26) of the platform is then moved to the rear. This part is locked to the rear corner fittings of the rear container. The spacing between the containers is thus increased. Spacers (50) on threaded rods (48) are inserted between two facing corner fittings and the rods are screwed up by hammerhead pieces (56) in the corner fittings.

IPC: A61M5/158
Filed: 1997-07-08
Abstract: The invention relates to a two lumen cannula (1) comprising an external cannula (2) designed as a perforation and incision cannula, and an internal cannula (3) which can slide in the external cannula and which, in a forward position, sticks out of the latter. These two cannulas (2, 3) are both bound to a respective blood hose (4, 5).

Title: Electronic timer, especially for differential pressure sensors
Inventor: KUDO TAKAHIRO
IPC: G01R23/02
Filed: 1997-09-03
Abstract: The circuit consists of a clock and a number of gates to measure the duration of the input pulse. The first gate switches at the start of the input signal and is latched until the end of the clock pulse when a first output signal is produced. The second gate switches on at the rising edge of the clock pulse and generates the second output signal. The second output is latched on the leading edge of the first signal and a third output is produced. A fourth output is produced at the falling edge of the second signal. The clock pulses are passed between the first and second output signals and are counted. A correction is made by half a counter value, on the basis of the third and fourth output signals.
