A thermal-conductive silicone composition containing (A) 0.5 to 2.5 mass % of a crosslinked silicone gel containing (a) an organopolysiloxane having at least two aliphatic unsaturated hydrocarbon groups per molecule, and having a kinematic viscosity at 25° C. of 10,000,000 mm/s or more, and (b) an organohydrogenpolysiloxane having two or more silicon-bonded hydrogen atoms per molecule; (B) 12.5 to 19.5 mass % of a hydrolysable organopolysiloxane compound; and (C) 80 to 85 mass % of aluminum nitride particles having an average particle size of 0.5 pm or more and 1.5 pm or less. A content of coarse particles in the aluminum nitride particles is 1.0 volume % or less relative to the whole. The coarse particles are 10 pm or more in a particle size distribution by laser diffraction. A thermal-conductive silicone composition has excellent coating workability and favorable pumping-out resistance, and is capable of attaining low thermal resistance by being thinly compressed.

An opening-closing member controller includes a control unit that executes an initialization process to store at least a fully closed position of an opening-closing member. In the initialization process, the control unit closes the opening-closing member, executes entrapment reversing control one or more times when entrapment is detected to open the opening-closing member, and closes the opening-closing member after the entrapment reversing control to store a position where the opening-closing member locks as the fully closed position.

Opening-closing member control device and initialization method

A cooler may include: a housing including a coolant space in which coolant flows; partition walls partitioning the coolant space into a plurality of flow channels; and a plurality of cooling fins located in each of the flow channels. The partition walls may be curved tortuously such that each of the flow channels comprises wide portions and narrow portions. The wide portions and the narrow portions may be arranged alternately in each of the flow channels in a direction along which the coolant flows. A number of the cooling fins located in each of the wide portions may be greater than a number of the cooling fins located in each of the narrow portions.
