摘要： An insulator is mounted in an armature core. Coils are wound around teeth of the armature core by way of concentrated winding. A power feeding member, which supplies a current to the coils, includes a connecting portion. A separating portion, which is provided in the insulator, is located in the teeth. The separating portion separates each of the coils to a first portion and a second portion. The connecting portion is electrically connected to the first portion. Accordingly, while preventing damage to the coils, the coils are easily connected to the power feeding member.

摘要： A mixture containing a magnetic powder, a binder, and an organic solvent is kneaded by passing it through a twin-shaft continuous kneader while the shearing force applied to the mixture is varied by changing the set angle of paddles used. The temperature of the mixture is controlled to be higher than Tg and lower than the boiling point of the organic solvent when it passes through the maximum shearing force zone, and to be lower than the temperature of the mixture upon its passage through the maximum shearing force zone, preferably lower than Tg when it passes through zones other than the maximum shearing force zone. There is obtained a magnetic recording medium which has improved dispersion of magnetic powder and excellent electromagnetic properties as well as a low coefficient of friction and improved transport stability.

摘要： A desk-top type computer with a built-in LCD includes a chassis, a planar display attached to the chassis, a mother board attached to the chassis, heat generating portions including a CPU mounted on the mother board, and a memory device electrically connected to the mother board. A heat receiving head is fixed to at least one of the heat generating portions including the CPU, and the head is connected a tube filled with a cooling liquid. The tube is arranged in a serpentine or zigzag shape in a clearance between the chassis and the planar display facing the chassis. The cooling medium liquid circulating in the tube serves as a heat transferring medium to absorb the heat at the heat generating portion, and radiate the heat through the tube disposed in the clearance between the LCD and the chassis.
