A pulse signal generator using a magnetic device that can cause a large Barkhausen effect, comprises means having a number of pits and projections and generates pulses according to the behavior of these, the means being capable of moving the pits and projections in a first or second direction, the pits and projections being disposed in the moving direction with some of the projections missing or some of the pits filled. The value of the ratio between the time interval of pulses generated by portions other than a projection-missing portion and the time interval of pulses generated by the projection-missing portion or the value of the ratio between the time interval of pulses generated by portions other than a pit-filled portion and the time interval of pulses generated by the pit-filled portion differs between when the pits and projections move in the first or second direction.

Pulse signal generator

A pulse signal generator comprising a magnetic element able ( ) to cause a large Barkhausen jump; a detection member ( ) for detecting a magnetic change in the magnetic element to generate a pulse signal; and a pair of magnetic field sources ( and ) provided in parallel to each other on both sides of the magnetic element such that their poles ( A, A) are opposed to each other so that when an object ( A) advances from one of opposite poles to the other of the magnetic field sources, a magnetic field applied to the magnetic element changes, causing a large Barkhausen jump in the magnetic element, thus causing the detection member to generate a pulse signal.

Apparatus for and method of generating a pulse signal

A pulse signal generator comprises a magnetic element ( ) capable of producing large Barkhausen jumps; a generating unit for generating a magnetic field, which is changed by the object to be detected ( ) to cause the magnetic element to produce the large Barkhausen jumps; the generating unit consists of a pair of elongated magnet/yoke combinations ( and ) provided on opposite sides of the magnetic element ( ) such that their poles are oriented in opposite directions, forming a detecting area at an end thereof ( A, A); a detecting unit ( ) for detecting the large Barkhausen jumps to produce a corresponding pulse signal; the magnetic element ( ) having a first length between a second length of the magnet/yoke combinations and a half of the second length and provided toward the detecting area; and an adjusting yoke ( ) movable along one of the elongated magnet/yoke combinations ( ).

Adjustment is made of the position of a marine transportation system including a boat having a drive, a trimmable port tab and a trimmable starboard tab. The operation of the marine transportation system is monitored to provide an output distinguishing boat operation in an on-plane condition and boat operation in an off-plane condition, to provide an output distinguishing boat travel in a straight forward condition and boat travel in a turning condition and to provide an output distinguishing boat operation in a first heel condition in which the boat tilts to port and boat operation in a second heel condition in which the boat tilts to starboard. The port and starboard tabs are positioned at desired positions in response to the outputs. According to the embodiment, a heel adjustment operation of the boat is carried out during boat operation in an on-plane straight forward travel condition, only.
