Inventor: IHLEFELD KARL-HELMUT
IPC: C04B28/22
Filed: 1980-03-03
Abstract: The concrete contains Portland cement as binder, and the mineral fibres consist of a puzzolan which forms calcium aluminate hydrate on reaction with the free lime of the Portland cement, and the concrete also contains lime-binding substances which promote this reaction in a controlled fashion. At the same time the reaction to form the calcium aluminate hydrate takes place only at the surface of the fibre, so that, provided the fibre is of adequate thickness, it will perform its reinforcing function for a long time. Suitable puzzolans from which such fibres can be made have a softening point of above 1000 DEG C. They are therefore suitable for reinforcing fire-resistant components. The fibre reinforcement can be introduced into the concrete in the form of mixtures of loose fibre sections, as a laid fibre web or as a laid woven fabric.

IPC: G11B23/18
Filed: 1980-07-02
Abstract: A blank disc (12) for a home video player/recorder has two or more reference tracks (41, 42) that are formed with the precision of a factory record and under the controlled environmental conditions of disc replication in a factory. When the disc is loaded into the player/recorder for a write operation, the player/recorder reads the reference tracks and simultaneously samples the track error signal and stores the error signal values in the data store of a processor. During the actual write operation, the processor operates on the stored values to generate a control signal to position the write head to define a track that follows the shape of the two adjacent reference tracks in proportion to the spacing of the track (40) between the reference tracks. Thus the player/recorder follows the precision factory reference tracks in spite of track distortion that usually occurs in a home redorder and in a home recording environment, and the track distortion of the home recorded disc is limited to about the track distortion of a factory recording.

The connector comprises a tricuspid fiber-receiving channel defined by three convex walls (12) connected along three longitudinal edges. The three convex walls are sufficiently rigid and uniform so that upon application of forces at the edges and directed toward the center of the channel defined by the convex walls, each of the three convex walls inwardly flexes in a uniform manner. As a result, abutting ends of optical fibers disposed within the channel defined by such convex walls will be tangentially engaged by each of the walls and the fibers will be aligned along a common longitudinal axis.

Abstract: A Deep Level Transient Spectroscopy (DLTS) method and apparatus, in which a high frequency measuring signal (10) is applied continuously on a semiconductor junction (13), and exciting pulses are generated which are coupled through fast semiconductor switching elements (15) to the junction to alternately bias the junction in reverse and forward (or slightly reverse) directions. The high frequency measuring signal passed through the junction is evaluated by means of a lock-in amplifier (24). 
     The evaluation circuits of the apparatus including the lock-in amplifier are controlled by switching elements driven by control signals generated by a control unit (32). The measuring time of the lock-in amplifier is controlled to start after a dead time after the beginning of the reverse bias pulse, which dead time is a fixed portion of the period of the exciting pulses.
