Abstract: A cooling unit has a member-to-be-cooled, a duct, and a cushioning material. The member-to-be-cooled has a plurality of cooling fins. The duct is fixed to the member-to-be-cooled, has a partition wall facing the plurality of cooling fins, and conveys a fluid to around the plurality of cooling fins. The cushioning material is disposed between the partition wall and the plurality of cooling fins and fixed to the partition wall.

Abstract: A cooling unit includes a member-to-be-cooled and a duct. The member-to-be-cooled includes a plurality of cooling fins. The duct is fixed to the member-to-be-cooled and has an outlet. The duct and the member-to-be-cooled define a cooling passage that conveys a gas to around the cooling fins and discharges the gas having passed the cooling fins through the outlet. The cooling passage includes a bend between the cooling fins and the outlet. The duct includes an outer corner that constitutes a partition wall on an outer peripheral side of the bend and the duct has a drain hole that is bored through the outer corner.

Abstract: A horizontal deflection circuit is provided which is useful in a television receiver and a video apparatus using a cathode ray tube, and which generates a deflection current for horizontally deflecting electron beams by changing a magnetic field applied to the cathode ray tube, and in which a resonance circuit using LC parts is not employed, and the vertical line distortion correction and the control of the horizontal deflection current in the multiscan are conducted by changing the duty ratios of switch elements, thereby simplifying the circuit configuration, and reducing the cost and the loss.
