摘要:
In a video signal transmission/reception system based on interlace scanning, video signals picked up by the sequential scanning are limited in vertical frequency band by filters (3a), (3b) and (3c) and transmitted as an interlace scanning video signal. Then, a signal of a predetermined vertical frequency band is extracted from the signal thus transmitted and a motion detection is carried out on the basis of the thus extracted signal.

There is provided a new glow plug that can be easily determined as to whether or not it is a new article.An additional circuit 12 formed by connecting a diode 13, a fuse 14, and an adjusting resistor 15 in series in this order is connected in parallel to a heating element 11 of a glow plug 1. The diode 13 is provided so as to have an anode located on the positive electrode side of the heating element 11 and a cathode located on the fuse 14 side. In the case of a unit inspection, by applying a positive voltage for test to a heating element negative electrode connecting portion 3a, it is possible to determine whether or not the glow plug 1 is normal without blowing the fuse 14 before the glow plug 1 is used in a vehicle.

A packet recording/reproducing system is provided which records or reproduces packets on or from tracks formed in time sequence on a magnetic tape. In a recording operation, the packet recording/reproducing system adds to input packets time stamps whose values are synchronous with packet arrival time control clocks produced by the system. The timing with which the packets are recorded on the magnetic tape is controlled by the arrival time control clocks so that a given number of the packets inputted at high data rate are recorded within a one-track area, a two-track area, or a one-track over area defined across at least two of the tracks, thereby minimizing the loss of capacity of the magnetic tape.
