Title: Magnetic recording and reproducing device
Inventor: KOTABE HIROSHI
IPC: G11B5/008
Filed: 1985-08-30
Abstract: PURPOSE:To reduce sufficiently adjacent crosstalk of a B-Y signal whose carrier frequency is low, by making the azimuth angle of a head, which records and reproduces a luminance signal, larger than that of a head which records are reproduces color signals. CONSTITUTION:A magnetic tape 1 is divided into two approximately in the breadthwise direction, and color signals are recorded on the upper half, and the luminance signal is recorded on the lower half. Since heads 5 and 5' for luminance signal are provided with 6-10 deg. small azimuth angle, the variance of the time base is very little even if tracking is deviated for reproducing, and sufficient outputs are obtained because the effective relative speed of heads are not reduced.

Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To immediately stop an engine and a motor in case of emergency by providing a path for absorbing the residual rotational energy of the generator on the upstream side of a circuit breaker for generator while branching. SOLUTION: An electric absorber, e.g., a resistor 15 or a power storage unit, for absorbing generated power is provided through a circuit breaker 14 in a path 25 branched from a power generating path 24 extending from a generator 2 to a circuit breaker therefore. Energy generated from the generator 2 is introduced to the absorber by turning a power generation circuit breaker 4 off and turning and absorption circuit breaker 14 on. Consequently, the residual rotational energy of the generator 2 can be absorbed to the absorber side regardless of a transmission path 21 on the downstream side of the power generation circuit breaker 4 at the time of stopping operation. Since the residual rotational energy of the generator 2 can be absorbed smoothly without having any adverse effect on the transmission path 21, the engine 1 and the motor 2 can be stopped quickly in case of emergency.
