Abstract: A starter motor electromagnetic switch which includes a single kind of electromagnetic switch that is capable of performing its necessary function even when two kinds of terminals are used in external connecting wires, thereby improving productivity and, when one of the two kinds of terminal in the connecting wires is a tightening type terminal, is also capable of surely preventing the terminal from turning. An L-shaped switch terminal is provided in such a manner that the bottom side portion thereof is fixed to an insulating cap and is connected by soldering to a lead conductor of an exciting coil. A screw terminal is received in the insulating cap such that it is prevented from turning. The threaded portion of the screw terminal is extended through and drawn out from the bottom side portion of the L-shaped switch terminal and is then fixed by a nut. In this manner, there is provided a single kind of electromagnetic switch which includes a switch terminal device consisting of two kinds of switch terminals.

Abstract: A vacuum boiler evaporator includes a sealed vacuum boiler vessel, a sealed vacuum condenser vessel which contains a partition that divides it into a first chamber and a second chamber that functions as a noncondensible gas collector, a conduit which connects the vacuum boiler vessel with the first chamber of the vacuum condenser vessel, a plurality of heat transfer tubes which extend through the first chamber and into the second chamber, and a return pipe which extends from the second chamber to the vacuum boiler vessel.

Abstract: A solenoid-operated switch for a starter comprises a movable contact driven by the action of a solenoid and a stationary contact facing the movable contact. An iron plate covers an area where the movable and stationary contacts are mutually brought to contact.
