Abstract: In an apparatus for reproducing, from a record medium, a recorded video signal including an FM-modulated luminance signal and a chroma signal which is down-converted from an original frequency band; the FM-modulated luminance signal reproduced from the record medium T is demodulated (14) and than the time-­base of the demodulated luminance signal is corrected (20Y, 20Y′), whereas, the time base of the down-converted chroma signal reproduced from the record medium T is corrected (20C,20C′) and then the reproduced chroma signal is up-converted (32) to its original frequency band. A servo circuit (7), for example, for controlling the rotary drum motor and/or the capstan motor of a video tape recording/reproducing apparatus (VTR) during a reproducing operation, is controlled in response to a phase difference between write and read addresses applied to a memory (20) of the time base corrector so that such memory (20) can be provided with a relatively small capacity.

Abstract: The distance between two objects, such as aircraft, helicopters and other vehicles, can be determined by transmitting from a first object through atmosphere a first frequency which is absorbed by atmosphere and a second frequency which is not absorbed by atmosphere, receiving at a second distant object the first and second frequencies, and determining from the received first and second frequencies the distance between the first and second objects. In preferred methods and apparatus, the first frequency is a frequency characteristic of atmospheric oxygen absorption (e.g., 760nm wavelength), and the frequency transmission comprises emitting a laser light beam while modulating its frequency through a frequency range which is greater than a frequency range characteristic of atmospheric oxygen absorption (e.g., 750nm-770nm wavelength) and includes a second frequency which is not absorbed by atmosphere.

Abstract: Cable deployment in a fluid filled pipeline under pressure is monitored by use of a strain gauge device (31) coupled between the leading end of the cable and a drogue. The strain gauge (31) measures the pull of the drogue on the leading end of the cable and the strain gauge signal is transmitted back to the other end of the cable via the cable conductors. 
     Changes in fluid flow rate, features of the pipeline, and failure of the drogue to inflate can be detected quickly by monitoring the strain gauge signal, so that the cable feed rate can be changed accordingly in order to maintain satisfactory deployment.

Abstract: In a TDMA cellular system, there is provided a mechanism for splitting the allocation of time slots within a TDM frame between adjacent coverage areas. There is provided a method of and apparatus for time-allocation of TDMA channels. It is characterized by: periodically allocating some portion of a carrier (19A-24A) of radio traffic to one coverage area during one time interval and periodically allocating some other portion of that same carrier (19B-24B) to another coverage area during a substantially non-overlapping time interval, all in time synchronism with any proximal reuse of that carrier. The distribution of channels in adjacent coverage areas thereby approaches parity (8+8+5 ≈ 8+8+3+3) and the minimum channel capacity per coverage area is enhanced (8+8 ⇒ 8+8+3+3; 16 ⇒ 22).

Abstract: A wireless telecommunication system includes a microwave link between a main base station (100) and a remote reception and radiation site (106) capable of communicating with a plurality of telephone subscriber stations (107, 108). At the main base station (100), radio frequency signals intended for the telephone subscriber stations are modulated on a microwave frequency carrier signal prior their transmission, via a microwave antenna (112), to the remote site. At the remote site (106), the frequencies of the microwave signals, received at a microwave antenna (114), are reduced prior to modulating such frequency-reduced signals on a radio frequency carrier signal and radiating, via a radio frequency antenna (115), the modulated radio signals out of the site. All radio signals received at the remote site from telephone subscriber stations are modulated on a microwave carrier signal prior to their transmission, via a microwave antenna (114), to the main base station (100). At the main base station (100), the frequencies of the incoming microwave signals are reduced prior to modulating such frequency-reduced signals on a radio frequency carrier signal and coupling the modulated radio signals to a receiver.

Abstract: An oriented silicon steel sheet having a very high magnetic flux density is produced from an oriented silicon steel containing AlN as the main inhibitor and also containing Sb by a method adapted to prevent the loss of the inhibiting ability of the surface layer of the steel, and to improve cooling conditions in annealing before the final cold rolling. The steel is hot rolled, subjected to at least one time the combination of annealing and cold rolling wherein the final cold rolling is performed with a rolling reduction of about 80 to 95 %, subjected to decarburization and primary recrystallization annealing, and subjected to, after coating an annealing separation agent, final finish annealing. Before annealing is performed before the final cold rolling, a nitriding promoter is applied to the surface of the steel sheet, and the partial-pressure ratio of N₂ in the atmosphere for that annealing is adjusted to a value of not less than about 20 %. In this way, it is possible to stably produce an oriented silicon steel sheet that exhibits a high magnetic flux density even with a small sheet thickness.

Abstract: The key-in-ignition warning switch (10) is integrally mounted within an ignition switch (11). The warning switch (10), positioned along the rotational axis (17) of the ignition switch (10), comprises an inner plunger (15), an outer plunger (16), a plunger spring (28), and a housing spring (31). As the ignition key (26) is inserted into the key cylinder (12), a linkage (14) between the key cylinder (12) and the warning switch (10) pushes against the inner plunger (15), which in turn pushes against the outer plunger (16). As the key (26) is inserted completely into the key cylinder (12), contacts (24,25) attached to the plungers (15,16) make contact with terminals (34,36) located within a terminal block (35) attached to the ignition switch (11). When both plunger contacts (24,25) and mating terminals (34,36) are in contact, the key-in-ignition warning circuit is completed, thereby enabling the associated warning devices.
