A magnetic-drive coupling pump configuration including an attachment/detachment mechanism allowing simple and reliable positioning and fixation is provided. Thrust-direction positioning and radial-direction positioning are achieved, respectively, by surface contact of a convex portion of a pump unit () inserted up to a predetermined position in a concave portion () of a drive motor unit (), and contact between an outer circumferential surface of the convex portion () and an inner circumferential surface of the concave portion (). A claw () protruding on the outer circumferential surface of the pump unit (), an engaging portion () protruding upward from an upper outer circumferential portion of the drive motor unit () to restrict, by engagement, claw upward movement when the pump unit () is rotated with the convex portion () inserted up to the predetermined position in the concave portion (), and a locking mechanism () holding the pump unit () at an engagement position of the claw () and the engaging portion () are included.

Pump configuration

A drive unit of a magnet coupling pump, in which leakage of the magnetic flux to the outside and the effect of the external magnetic field are suppressed. The drive unit includes: a driving magnet () positioned at an outside of the driven magnet () of the magnetic coupling pump () with respect to a rotation axis (A) of the magnetic coupling pump () to face the driven magnet () with a gap; a cup tube portion () made of a ferromagnetic material and in a tubular shape centered on the rotation axis (A); a case main body () including a cup () in which the driving magnet is fixed inside of the cup tube portion; a motor () rotating the cup around the rotation axis, and a tube portion (), which is tubular in shape. The cup is provided in the tube portion () with a gap.

A control apparatus of an internal combustion engine, for preventing a throttle valve from freezing when the internal combustion engine is stopped. A control unit is constructed to receive power from a battery ancillary to an internal combustion engine when the internal combustion engine is stopped and perform a probability determination of whether or not the probability of a throttle valve freezing is high. When this probability is high, the control unit controls the throttle valve to execute a freeze protection operation, including a valve opening and closing operation of the throttle valve, before the throttle valve freezes. The probability determination is carried out using environmental temperature detecting means, engine temperature detecting means, date/time information outputting means, location information detecting means, and a drive level of an exhaust recirculating device.

A vehicle safety device designed to reliably prevent uncontrolled travel or runaway of a vehicle when a collision accident occurs. A breaker is connected in a current path between a battery and a controller. In a processing section of a distance measuring unit, a time difference between the moment at which a laser light emitting section emits light and the moment at which a laser light receiving section receives light is detected and the distance and the relative speed between the vehicle and an object against which the vehicle may collide are calculated. When the distance between the vehicle and the object becomes zero while the relative speed between the vehicle and the object is larger than a predetermined value, the processing section determines that a collision has occurred, and supplies a control signal to the breaker to open the same.
