Abstract: A coil component includes a drum-shaped core including a core portion that extends in a length direction of the coil component and a first flange portion provided on a first end portion of the core portion, and first and second terminal electrodes provided on the first flange portion. The first and second terminal electrodes each include a base electrode formed on a surface of the first flange portion and a plating layer that covers the base electrode. The base electrode includes a bottom-surface base electrode portion on a bottom surface, an end-surface base electrode portion on an end surface, and a side-surface base electrode portion on a first side surface. The end-surface base electrode portion has a height greater than that of the first crotch portion. The side-surface base electrode portion has a height less than that of the first crotch portion.

Abstract: To secure enough of an amount of intake air and an increase in a flow rate in a balanced manner to improve a filling efficiency for increasing power in an internal combustion engine. A combustion chamber is formed between a cylinder block and a cylinder head opposite to a top portion of a piston slidably fitted in the cylinder block. An intake path extends from an inlet pipe, separately or integrally, connected to the cylinder head to the cylinder head and is in communication with an intake valve port that opens to the top surface of the combustion chamber to be opened/closed with the intake valve. Intake paths are provided with a pair of throttle portions arranged with an interval in an air flow direction of the intake paths and an expanding portion positioned between the throttle portions.

Abstract: A process for removing an anthraquinone type scale comprises condensing a steam evaporated from a black liquor obtained by separating pulp from a digested mixture of lignocelluloses containing an anthraquinone type digesting assistant; and contacting a heated aqueous solution of a base in the presence or absence of a reducing agent or an alkali resistant surfactant with a wall of a condenser of an evaporator on which said anthraquinone type scale is adhered.
