Abstract: PURPOSE: To prevent frictional force from increasing by providing a cage holding a ball disposed between an inner race and an outer race of a bearing to be used for mounting a carriage supporting a head on a base within a prescribed range with a hole for supplying grease which extends toward the ball. CONSTITUTION: An upper bearing part 1U is provided with an outer race 8U which is disposed coaxially with an inner race 6U so as to be opposed to the inner race 6U and a cage 12U constituted of a hollow cylindrical member in which a plurality of recessed part 11U storing a plurality of balls 10U disposed between the inner race 6U and the outer race 8U one by one are formed on a lower surface. Because cages 12U, 12D are provided with holes 18U, 18D for supplying grease which extend toward each of balls 10U, 10D, grease is supplied to only balls 10U, 10D which actually require lubrication. Therefore, extra grease does not enter a gap between a shaft 2 and the cages 12U, 12D, and frictional force between the shaft 2 and the bearing 1 is not increased.

Abstract: PROBLEM TO BE SOLVED: To prevent overcharge of a unit battery having a minimum capacity independent of the dispersion of capacities of unit batteries and lengthen the life of an assembled battery by discharging a plurality of unit batteries constituting the assembled battery by the same capacity from the full charge state, and assembling the unit batteries in a rechargeable capacity state. SOLUTION: The unit battery of a secondary battery manufactured in the specified process is charged at the specified current, charged at constant current for specified time to maintain voltage, then discharged at the same current until reaching the specified voltage. This charge/discharge is repeated and when the discharge capacity dropped to 70% or less of the initial capacity is defined as the life of the unit battery, after the upper limit voltage in charging reached the critical voltage, the number of the charge/discharge cycles by the life is sharply decreased. When the state charged to the critical voltage is defined as a full charge state, the unit battery charged to the full charge state is discharged to 75% of the standard capacity, and these unit batteries are assembled to constitute an assembled battery.  Thereby, overdischarge caused by the dispersion of capacities of the unit batteries can be prevented.

Title: High frequency heating apparatus
Inventor: IKEDA YOSHITAKA
IPC: H05H1/18
Filed: 1988-12-07
Abstract: PURPOSE:To efficiently cool a microwave oven, lessen high-frequency loss thereof and obtain mechanical strength thereof endurable against electromagnetic force by employing a material with low electric conductivity as a short edge side-member forming a waveguide and a material with high electric conductivity as a long edge side-member forming thereof and joining the members to each other. CONSTITUTION:A material with high electric conductivity is employed as a long edge side-member 10 of a rectangular waveguide. And also a material with low electric conductivity is employed as a short edge side-member 11 thereof. A joining portion 12 where the members are to be joined to each other is diffused in solid phase to form the waveguide. Since the material with high electric conductivity is employed as the long edge side-member 10 of the rectangular waveguide, thermal conductivity is improved, quantity of heat passing through the waveguide becomes large and cooling effect is improved. Moreover, high-frequency loss and Joule loss are lessened. This leads to less heat generation. On the other hand, because of employing the material with low electric conductivity as the short edge side-member 11, an eddy current, which is to be induced when plasm is disappeared, is lessened and electromagnetic force operating by magnetic field is also lessened. Therefore, such as supporting configuration of the waveguide is simplified.
