摘要:
A method for obtaining grain-oriented silicon steel sheet with a very high magnetic flux density and a very low core loss by setting specific conditions for the decarburization and primary recrystallization annealing step within the series of steps performed for the manufacture of the grain-oriented silicon steel sheet. This method consists of setting the rate of temperature rise in the decarburization and primary recrystallization annealing step at no less than 10.degree. C./sec, dividing the decarburization and primary recrystallization annealing step into a first half and a second half, and restricting the temperature, time, and ratio P.sub.H.sbsb.2.sub.O /P.sub.H.sbsb.2 of the partial pressure of H.sub.2 O to the partial pressure of H.sub.2 of the atmosphere for each of these two halves within certain predefined ranges.

The life of a lead acid storage battery is extended by changing an over-frequency equalized charge interval performed on a lead acid storage battery, in accordance with a transition situation of a state of charge (SOC) of the lead acid storage battery. The lead acid storage battery is also made to be advantageous in terms of cost by reducing the equalized charge with a low degree of urgency to reduce the power and cost for equalized charge, and by reducing the number of stops of a natural energy storage system. A lead acid storage battery and a lead acid storage battery system whose operational management can be easily performed are achieved by a method in which the future timing when the equalized charge is performed can be grasped by people operating the lead acid storage battery.

A noise removing filter removes noise from an input image and an edge component extracting unit extracts edge components. The edge components are extracted by calculating a difference between the input image and a smoothed image, which is obtained by smoothing the input image in a smoothed image generating portion. An edge component comparing unit compares the extracted edge components with a threshold value and a sum calculating unit calculates the sum of the edge components greater than the threshold value. A control circuit determines, the enhancement degree of the edges based on the sum and averaged luminance of the input image calculated by an average luminance calculating unit. An enhancement degree adjustment unit adjusts the determined enhancement degree, and an edge component enhancement unit enhances the edge components based on this enhancement degree and adds it to the input image to perform edge enhancement processing.

A method for docking/undocking a portable computer to/from an expansion unit is disclosed. The portable computer includes a main battery, and the expansion unit includes a second battery. In response to an eject event, the condition of the second battery is determined. If the second battery is in a discharging condition, a power supply route is switched from the second battery of the expansion unit to the main battery of the portable computer. If the second battery is in a charging condition, the charging condition is suspended. At this point, a hot undocking of the portable computer from the expansion unit can be performed.
