Filed: 1988-12-14
Abstract: PURPOSE:To detect the abrasion of a brake lining automatically by detecting the current flowing when applied in low voltage AC to brake coils of a motor equipped with a brake which is supplied to the motor when brake coils are demagnetized. CONSTITUTION:A three-phase induction motor 14 rotates when three-phase power R to T are supplied at contactors 13, while a changeover switch 15 is connected on the contact (a) side and each brake coil 1a to 1c is excited to put off an electromagnetic brake. The changeover switch 15 is then connected on the contact (b) side and a weak current which is insufficient to put on the brake is caused to flow to coils 1a and 1b from an AC power source 16. The voltage across a resistance 17 for detection is applied to a detection circuit 18, which is compared with the output of a setter 19 to detect whether or not a brake shoe is beyond the limit gap. When the brake shoe exceeds the limit, then an alarm lamp 21 is turned ON and a contact 20a is closed to output a signal. The time to exchange the lining of the electromagnetic brake and the time to adjust the gap can thereby be detected easily.

IPC: H04N9/896
Filed: 1993-12-16
Abstract: PURPOSE:To reduce the cost by reducing a storage capacity of a memory in the digital time base corrector. CONSTITUTION:Absolute value data of an amplitude and polarity data of a bust signal in a color video signal are written to a memory 11 for each one- horizontal scanning period, and a signal excluding a signal for a synchronizing signal period, a pedestal level period and a burst signal period in the color video signal is written in the memory 11 as image data. Absolute value data, polarity data and image data are read from the memory 11, the burst signal data are reproduced based on the absolute value data and the polarity data, and the color video signal is reproduced by inserting the burst signal data, the synchronizing signal data and the pedestal level data to the image data. Since it is not required to write the burst signal in the color video signal processed into digital data as they are to the memory, the storage capacity of the memory is largely reduced than that of a conventional memory and the cost of the corrector is reduced.
