Title: High-frequency voltage and current measurement device for conductor
Inventor: WILKEN LUDGER
IPC: G01R19/28
Filed: 1995-09-07
Abstract: The device measures voltages and currents of any amplitude on a line of any wave impedance by means of a voltage pick-up and current transformer respectively.

Title: Semiconductor device with contact hole manufacturing method for e.g. MOS transistor of memory
Inventor: KIMURA HIROSHI
IPC: H01L21/768
Filed: 1996-03-15
Abstract: The initially involves depositing a conduction region (3) in the upper surface of a semiconductor substrate (1) and depositing three insulating layers (11,13,15) on one another on the upper surface of the substrate, the intermediate layer being deposited at a different etching rate then the other two. The upper of the three insulating layers has an opening over the conduction region. A sidewall layer (17) is deposited on the sidewall of the opening and the intermediate insulating layer is subsequently etched using the sidewall and the upper insulation layer as a mask until the lower insulation layer is exposed, forming a second opening (25).  A fourth insulation layer (19), acting as a planarisation layer, is deposited on the upper layer and also fills the opening, and a resist (33) with a hole pattern of diameter grater than that of the opening is provided over the opening. The four insulation layer and the side wall are then etched under such conditions that three insulation layers (11,15,19) are extracted and the etching of the intermediate layer (13) is impeded due to the resist mask. This provides a hole via which the conductive region is reached and a conductive layer is provided in the hole to the conductive region.

Title: Vehicle wheel hub bearing seal
Inventor: EISENKOLB ROLAND
IPC: F16J15/3232
Filed: 1997-04-19
Abstract: The bearing has a seal with two lips (4) which are directed away from each other in which the transition zone (5) to the support zone (2) is more flexible than the two sealing lips.
