Abstract: A cutting insert includes first and second polygonal surfaces and a plurality of side surfaces. A corner edge that has a corner rake surface on the first polygonal surface is formed at a first corner portion, and a main cutting edge is formed from the corner edge to a second corner portion. The main cutting edge includes, at least on a corner edge side, a rake angle gradual increase region where a rake angle of a main rake surface gradually increases to a positive angle side as going from a first end portion of the corner edge toward a second corner portion side.

Abstract: A cutting insert includes an insert body; a pair of first surfaces; a through hole extending in a direction of a first axis; a second surface which connects the first surfaces and faces a direction of a second axis orthogonal to the first axis; a third surface which is disposed on the circumferential surface and is connected to the first surfaces and the second surface and faces a direction of a third axis; and cutting edges located at an intersection ridge line between the first surface and the second surface and at an intersection ridge line between the second surface and the third surface. The second surface has a projection part protruding in the direction of the second axis, and as viewed from the direction of the second axis, the through hole and the projection part are disposed to overlap each other.

Abstract: In order to heat and warm only the amount of water required in immediate future and to reduce a power consumption by avoiding warming of unnecessary water, a main body provided with a water storage container and a water heating container can be attached and detached and a water heating amount or a water warming amount to be heated at one time is reduced and divided, thus, power consumption during warming is reduced. Furthermore, since the water storage container is provided independently, water supply can be carried out conveniently regardless of the state of the water-heating container. Water supply to the water-heating container is carried out automatically using a water amount sensor, hence no operation by a user is required.

Abstract: A coffee maker is provided in which remaining water can be taken out easily, hot water is delivered intermittently to brew nice coffee. A hot water reservoir in the coffee maker has a tube provided on a bottom thereof for delivering the hot water to a coffee brewing chamber and a cap arranged with a space from the tube by a distance which is not greater than the maximum inner diameter of the tube.

Abstract: An automatic bread producing apparatus has a baking chamber. A temperature sensor is operative for detecting a temperature within the baking chamber. A first device is operative for detecting a room temperature. A second device is operative for determining a corrective value in response to the room temperature detected by the first device. A third device is operative for correcting a first control temperature into a second control temperature in response to the corrective value determined by the second device. A fourth device is operative for controlling a bread producing process in response to the temperature detected by the temperature sensor and the second control temperature provided by the third device.
