Patent EP-0459054-A1 (EP)
Inventor: ZOELLICK RAYMOND D
IPC: H01R9/22
Filed: 1990-09-20
Abstract: An isothermal block (70) has a multi-layer thermal conductor (76a-76f) interleaved with different layers (86a-86d,88a-88c) of a printed circuit board to provide improved thermal coupling of input terminals and a local temperature sensor mounted on the isothermal block (70). Each of the layers (76a-76f) of the thermal conductor is substantially thinner than substrate layers of the printed circuit board. The layers (76a-76f) of the thermal conductor are spaced apart from the terminals so as to be electrically isolated from the terminals. Embedded layers (76b-76e) of the thermal conductor are spaced closer to the terminals than are external layers (76a,76f) of the thermal conductor.

Abstract: The invention relates to integrated circuits, and more particularly those whose operation necessitates a clock. This is the case especially for microprocessors, microcomputers and many other integrated circuits. According to the invention it is proposed that the circuit comprises a means (level detector DET and frequency divider DIV) for reducing the clock frequency (CLK) of the integrated circuit when the supply voltage Vcc of the circuit falls below a defined threshold for which the operation at normal frequency risks no longer being correct. Thus the management of transient phases of starting and stopping of the circuit are simplified. <IMAGE>

Abstract: A coating is now disclosed which is especially serviceable as an improved electrocatalytic coating for an electrode. The coating is a crystalline coating of mixed oxides. The oxides are of iridium, ruthenium and titanium, in very specially defined proportions. When the coating is present on an electrically conductive metal substrate that can serve as an electrode, such electrode has, in combination, the characteristics of reduced oxygen evolution in a membrane cell, low chlorine electrode potentials, plus reduced coating weight loss in a caustic environment.

Abstract: A locking clamp is known, with which a wall trunking covering part can be held in a wall trunking lower part. At the same time, this locking clamp has a contact tip, constructed as a cutter, in order to scratch insulating varnish layers and thus facilitate an electrical connection between the covering and lower part. Fault-free scratching cannot reliably be achieved using this clamp for thick and/or hard insulating layers. In the new locking clamp (10) a contact lug (11) is provided which has a plurality of contact cutters (13, 14, 15) arranged one behind the other in the insertion direction (A) of the covering part (30). The subsequent contact cutters (14, 15), which move along in the same scratching track during pushing-in, thus ensure an electrical connection in every case, even in the case where the front contact tip (13) is blocked with material which has been lifted off or has not completely scratched through the insulating layer. A locking clamp for wall trunking holding electrical installation devices, for the retention and electrical connection of a covering part to a lower part. <IMAGE>

Abstract: A method of manufacture of, and apparatus for, a torque converter assembly having an improved reactor assembly (200). A torque converter is disclosed having a stator which has improved and simplified casting and machining requirements. A stator hub (214) is provided having a cylindrical bore (216) substantially coaxial with the axis of the transmission shaft to which the torque converter is mounted. An overrunning clutch and thrust bearing cartridge assembly (250) is provided to be fitted into the stator hub bore (216). The overrunning clutch provides improved lubrication on both sides of the clutch engaging element (262) surfaces, either rollers or sprags, between the inner (254) and outer rings (252) which form the clutch races. Wear surfaces (266,282,284) within the clutch assembly are stamped steel instead of aluminum. Clutch load is increased by increasing the roller or sprag (262) dimensions in the direction of the stator axis, while maintaining the same stator hub width. Thrust bearings (240,242) are mounted to the outside of the overrunning clutch.

Abstract: An X-ray image pick-up method causes X-rays from an X-ray source to be irradiated on an object for picking up its image as passed through a filter capable of restricting any fluctuation in effective X-ray energy within ±10%, and then the X-rays thus penetrated through the object to be picked up by an image pick-up means. Radiation dose with respect to patients as the object and eventually to doctors or X-ray operators is thereby minimized, while the image pick-up can be realized with a high resolution.

Abstract: An ECG system is disclosed having amplification circuitry which, while effectively blocking electrical transients resulting from undesirable low frequency electrical artifacts, nevertheless maximizes the continuity of receipt of desirable heart activity indicating information. The ECG system employees a DC coupled amplifier (138) including an integrating circuit (134) for effectively reducing the DC gain of the amplifier to substantially zero and for providing a pass band gain of about 1,000 at frequencies above about 0.05 Hz. A fast acting saturation sensing circuit (152,154) is also incorporated. The saturation sensing circuit resets the integrating circuit to offset any artifact produced signal and to thereby minimize loss of the desired ECG hear activity indicating information.
