Abstract: Thermal spraying may be readily carried out using fine particles which were difficult to be handled in the conventional art by using particles of a resin containing the fine particles of a ceramic or a metal as a material for thermal spraying. To produce a material for thermal spraying, the fine particles are dispersed in a liquid resin, and a cured material obtained by curing the mixture is pulverized to obtain a material for thermal spraying which contains particles having a particle diameter within a target particle diameter range, and these operations are repeated. In the second or later time production of a material for thermal spraying, over-pulverized particles which were obtained in a completed pulverization step of a cured material and have a particle diameter below the target particle diameter range are also added to a liquid resin and are disperse in the step for dispersing fine particles in a liquid resin.

Abstract: A vehicle heating system comprising: a coolant circuit that circulates coolant between an engine and a heater core; heating device that heats coolant, which is interposed in the coolant circuit; a pump for coolant circulation, which is interposed in the coolant circuit; and a switching valve that switches the coolant flowing through the coolant circuit between a heater-core-side circuit that circuits the coolant among the heater core, the pump and the heating device and an engine-side circuit that circulates the coolant into the engine, wherein the switching valve has a thermo valve that switches channels so that the coolant coming from the engine-side circuit enters either one of the heater-core-side circuit and the engine-side circuit according to temperature of the coolant, and a bypass that delivers the coolant, which comes from the heater-core-side circuit, to the heater-core-side circuit.
