    摘要： Problems of a dead-time due to a make-contact delay time until the closure of the regeneration contactor and a drop of torque occurring in the prior art controller for an electric vehicle are solved by the invention, thereby providing an improved drive feeling during transition from its regenerating braking to plugging braking. Specifically, a regeneration contactor's contact voltage is entered to the arithmetic unit, upon set-up of a condition for stopping the regenerating braking, the control for closing the regeneration contactor is executed, and immediately upon detection of the actual closure thereof, the switching operation is cut off at a timing faster than the switching cycle thereby allowing for the transition to the plugging braking to be enabled.

    摘要： Accumulation of heat in the electronic appliance is prevented, and the electronic appliance is cooled efficiently. Not requiring extra molded part as duct, the cost is saved. The noise level is lowered. This is a cooling structure for an electronic appliance having heat generating parts. The cooling structure includes a housing having a top panel, side panels, and a bottom panel, a case disposed in the housing, a circuit board disposed in the case, and a frame disposed in the space between the top panel and case. The circuit board has the heat generating parts. The space enclosed by the top panel, case and frame forms a wind tunnel. The heat generated in the heat generating parts is exhausted outside of the housing by the air passing through the wind tunnel. The case and the circuit board have the circuit board disposed in the housing, and a shield case disposed to cover the circuit board.

    摘要： The invention relates to a process and apparatus for separating mixed gas by adsorption in which adsorption and desorption steps are repeatedly carried out in a plurality of adsorption towers in staggered timings.The invention is characterized in that upon commencement of the desorption step, mixed gas having a low adsorbate constituent gas concentration which is delivered in the initial part of a pressure-reducing period (a primary pressure-reducing period) in an adsorption tower which has completed adsorption, is fed into an adsorption tower which has finished pressure-reduction to scavenge and desorb the adsorbate constituent gas adsorbed by an adsorbent, whereby enhancement of a yield of an unadsorbate gas can be achieved as compared to scavenging desorption making use of a part of an unadsorbate gas delivered during an adsorption step.
