摘要： A marine autopilot apparatus having a microcomputer for controlling a rudder control loop formed of at least a rudder servo amplifier, and a power unit, for detecting an abnormality concerning the steering of a rudder and for indicating an alarm concerning the detected abnormality and the like. A representing alarm indicator lamp classifying the abnormalities into a single or plurality of groups and for collectively indicating the abnormalities in the form of the single or plurality of groups. A general-purpose indicator for indicating various data at least concerning the steering, set values and respective contents of the abnormalities detected and a rudder control collective alarm circuit for indicating the occurrence of the abnormality in the rudder control loop. The rudder control collective alarm circuit is driven when at least one of a plurality of alarm points within the rudder control loop, and the power unit exhibits an abnormal condition.

摘要： A proportional electromagnetic valve includes a valve main body having a valve member, a solenoid to drive the valve member, and an amplifier unit to control the solenoid. The solenoid is attached to one or both side portions of the valve main body. The amplifier unit has a size which is almost equal to a size on the unit attaching surface side of the valve main body and solenoids. The casing of the amplifier unit has an enclosing space large enough such that single printed board having all of drive amplifiers attached there to placed in the casing of the amplifier unit.
摘要翻译：比例电磁阀包括具有阀构件的阀主体，用于驱动阀构件的螺线管和用于控制螺线管的放大器单元。螺线管安装在阀主体的一侧或两侧。放大器单元的尺寸几乎等于阀主体和螺线管的单元安装表面侧上的尺寸。放大器单元的壳体具有足够大的封闭空间，使得具有附接到其上的所有驱动放大器的单个印刷电路板放置在放大器单元的壳体中。
