    摘要： A numerical control device comprises a box structure, a board unit housed inside the box structure, a wire distribution board disposed on the rear surface of the box structure, and a fan unit detachably mounted to the top surface of the box structure. The fan unit has a fan motor inside. A first connector wired from a power supply terminal is secured to the box structure while a second connector wired from a fan motor is secured to the fan unit at a position opposite the first connector secured to the box structure. Thus, the second connector can be connected to and removed from the first connector.

    摘要： A heat radiating type liquid level sensor comprises a liquid level measuring resistor having a first temperature coefficient and an inverting amplifier gain of which is dependent on the change in resistance of an input resistor thereof. The input resistor has a second temperature coefficient. The liquid level measuring resistor and the input resistor are placed side by side so that the input resistor can experience the same ambient temperature as the liquid level measuring resistor. The first temperature coefficient is set to a greater value than that the second temperature coefficient taking into consideration the temperature dependency of the resistor-to-air thermal resistance Rth of the liquid level measuring assembly, the temperature coefficient of the liquid level measuring resistor Ro, changes in liquid level due to thermal expansion of the liquid, and the maximum liquid level of the liquid tank, so that the liquid level sensor can provide an output indicative of the total weight of the liquid in the liquid tank. The desired value of the second temperature coefficient may be achieved by combining, in series connection or parallel connection, a resistor Ri of the same lot as the liquid level measuring resistor Ro is manufactured and a resistor Rs that has a negligibly small temperature coefficient as compared to that of Ri.

    摘要： A fan motor is mounted on the upper wall of the casing. The lower surface of this upper wall is formed into an inclined surface in which inclination is formed from the front wall side of the casing toward a back wall across from the front wall. When the fan motor is driven, oil mist or moisture contained in the air are condensed into water droplets or oil droplets. These water droplets or oil droplets fall and flow to the inner wall surface of the upper wall of the casing along the inner peripheral wall of a vent hole. Then the water droplets or oil droplets flow along the profile line of a vent hole smoothly (without stopping) and roll down the side wall of the casing.

    摘要： A casing structure for a numerical control unit in which a cooling fan mounted on a fan cover is electrically connected with a control board attached to a main cover without using cables. A terminal unit connected with wiring of a fan motor is fixed to a fan cover, and a power supply terminal to be directly connected with the terminal unit is fixed to an upper end portion of a main control board The terminal unit is connected with or disconnected from the power supply terminal by attaching or detaching the fan cover to or from a casing body. Since cables are not needed for connection, a casing can be assembled and disassembled easily. Further, since an assembling error due to interference of cables is eliminated, automation of the assembling work can be easily achieved.
