摘要:
In an agitating type washing machine a washing drive motor is run reciprocally in opposite directions to rotate an agitating wheel within a washing tank alternately in one and the other directions to perform intended washing, the washing machine comprises a rotational angle detector for detecting an angle of rotation of the agitating wheel, and a control for controlling the motor in response to a detection signal from the rotational angle detector. The control interrupts energization of the motor when the angle of actual rotation of said agitating wheel or the number of rotations of the motor reaches a predetermined value, the control means controlling the motor to run in a reverse direction when rotation of the agitating wheel by inertia in one direction is almost stopped.

In an agitating type washing machine a washing drive motor is run reciprocally in opposite directions to rotate an agitating wheel within a washing tank alternately in one and the other directions to perform intended washing. The washing machine comprises a rotational angle detector for detecting an angle of rotation of the agitating wheel, and a control for controlling the motor in response to a detection signal from the rotational angle detector. The control controls such that an angle of rotation of said agitating wheel by energization of the motor during running under a load is made smaller than that during no load running and that changing over between running under a load and no load running is automatically effected in response to a detection signal from the rotational angle detector, and controls rotation of said agitating wheel to an angle equal to or less than 360 degrees including rotation by energization of the motor and rotation by inertia whether during running under a load or no load.

Proposed is a box container suitable for holding and transporting a plural number of sheet-like bodies such as lead frames for semiconductor devices such as ICs. The box container consists of three parts including (a) an inner box member to hold the sheet bodies, (b) a box tray member into which the inner box member is inserted and (c) a covering member to be engaged with the box tray member. The inner box member is an integral plastic body consisting of a generally rectangular base plate and side plates each connected, independently from the others, at the bottom line to one of the four sides of the base plate while each of the side plates is jointed to the base plate not perpendicularly but with outward inclination from the bottom to the upper periphery in such a resiliently bendable fashion that, when the inner box member is inserted into the box tray member, each side plate is contacted with the side wall of the box tray member with resilience to take a perpendicular disposition to ensure little play between the side plates and the sheet bodies therein while good working efficiency is ensured in putting and taking sheet bodies into and out of the inner box member.
