Patent EP-0307503-A1 (EP)
Inventor: GHEEWALA TUSHAR RAMESH
IPC: G01R1/073
Filed: 1987-09-18
Abstract: A test structure for integrated circuits allows full testing of highly complex integrated circuits. The test structure consists of a grid of externally as well as individually accessible probe-­lines and sense-lines with electronic switches at the crossings of said probe and the sense-lines. One end of the switches is tied to an array of test-points on the IC that are to be either monitored or controlled during the testing, and the other end of the switches is tied to a sense-line . The ON and the OFF states of the switches are controlled by probe-lines. The probe and sense lines are connected to test electronics, thus permitting the test electronics to control the electrical signals on the probe-lines and to measure or apply signals on the sense-lines. Thus, by the excitation of an appropriate probe-line and the monitoring of an appropriate sense-line, the test signals present at any one of the test-points can be measured. Conversely, by the excitation of an appropriate probe-line and application of a test signal on another appropriate sense-line the electrical signal on any of the test-points can be externally controlled for the purpose of testing.

Inventor: BELL ANTHONY JOSEPH
IPC: C08F36/06
Filed: 1987-01-23
Abstract: Short fibers of syndiotactic 1,2-polybutadiene are utilized in making tires that have improved resistance against heat build-up and improved wear characteristics. The preparation of syndiotactic 1,2-polybutadiene in fibrous form has traditionally involved an extrusion and stretching step. However, the technique of the present invention circumvents the necessity of hot mill flexing and/or extrusion in making fibrous syndiotactic 1,2-polybutadiene. The present invention more specifically involves a process for preparing syndiotactic 1,2- polybutadiene fibers directly comprising polymerizing 1,3-butadiene monomer in the presence of (1) a catalyst composition which is comprised of (a) a cobalt compound and (b) an organoaluminum compound; (2) carbon disulfide; and (3) at least one member selected from the group consisting of liquid polymers and naphthenic oils.

Title: Apparatus for simultaneous determination of ophthalmic artery blood pressure and flow.
Inventor: STRAUSS ANDREAS LADISLAUS
IPC: A61B3/16
Filed: 1987-01-09
Abstract: The apparatus comprises a chamber (1) enclosed on all sides except for an opening (3) on one side to permit hermetical contact with the orbital borders. The chamber is equipped with a device (4) for increasing the pressure within the chamber, coupled to a manometer (6) and has a doppler probe (5) that may be connected to a doppler flowmeter. Applying an increasing positive pressure in the chamber, and thus upon the contents of the orbit, the doppler probe detects the moment of disappearance and reappearance of the blood flow signal, respectively. The point at which the signal ceases or first reappears corresponds to the systolic blood pressure in the ophthalmic artery.
