The invention provides an apparatus, program, and method for controlling the automatic spraying of an antifreezing agent that can reduce the cost of the antifreezing agent and the impact of salt damages caused by the antifreezing agent. This is accomplished by reducing the amount of antifreezing agent to be sprayed automatically according to road surface condition and reducing the amount of the antifreezing agent left unused on completion of the spray operation by grasping in advance the total spray amount of the antifreezing agent. Thus, the antifreezing agent automatic spray control apparatus comprises a spray section setting unit for setting a spray section, a road surface condition data acquiring unit for acquiring road surface condition data, a spay condition data acquiring unit for acquiring spray condition data, a spray condition determining unit for determining the spay conditions for each of unit sections, a total spray amount advance calculating unit for calculating in advance the total spray amount of antifreezing agent to be sprayed for the spray section, a current position data acquiring unit for acquiring current position data, a unit section identifying unit for identifying a unit section corresponding to the current position, and a spray condition outputting unit for outputting the spray conditions for each of the unit sections to an antifreezing agent spraying unit.

The present invention provides a tire internal pressure warning system, comprising: an internal pressure data acquisition apparatus for obtaining data of internal pressure of each tireof a vehicle(a TPMS sensor transmitterand a TPMS receiver); and an information terminal devicefor determining whether there is a puncture-based failure or a failure resulting from a natural pressure drop, based on a change in the internal pressure of each tire received from the TPMS receiver, and displaying a warning in accordance with the failure condition.

To reliably supply a predetermined amount of sealing agent into a pneumatic tire even if the device is inclined and after the predetermined amount of sealing agent is supplied, to automatically start feeding compressed air into the pneumatic tire. In pumping device, when compressed air is supplied to air chamber, internal pressure of air chamberincreases, and as the internal pressure of air chamberrises, a contained volume of air chamberincreases while a contained volume of liquid containerdecreases. Thus, sealing agentin an amount corresponding to the amount corresponding to the reduction in the contained volume of liquid container, is forcibly discharged from discharge outletand the discharged sealing agentis injected into tire. In pumping device, when the air chamberexpands enough to have a predetermined amount of sealing agent to be discharged from the liquid container, the air discharge openingopens toward the air chamberto allow the air chamberto communicate with the inside of tire. Thus, compressed air in the air chambercan be supplied into tirevia the air discharge outlet, bypass hoseand joint hose

A magnetic powder for bonded magnets is obtained by subjecting starting magnetic particles to agitation in a high speed air stream whereby individual particles are mechanically impacted with one another by the action of the stream. A magnetic composition comprising the magnetic powder and a resin binder is also described wherein the magnetic powder can be highly packed in the resin binder to ensure good fluidity of the composition. The magnetic composition can be prepared by mixing magnetic particles and a resin binder powder, subjecting the mixture to agitation in a high speed air stream for impactness of the particles and heading the mixture or by subjecting magnetic particles to agitation in a high speed air stream, mixing the agitated particles with a powder of a resin binder and heading the resultant mixture.
