Abstract: An image processing apparatus obtains a plurality of pieces of image data with different exposure amounts and then performs a level-conversion of the image data by applying input/output characteristics thereto. The apparatus encodes the image data whose level has been converted and decodes the encoded image data. The apparatus further applies inverse characteristics of the input/output characteristics to the decoded image data and then generates combined image data. In generating the combined image, the input/output characteristics are set in accordance with a combining ratio of each of the image data.

Abstract: An information processing apparatus includes: a body having a top configured to allow a touch panel to be disposed thereon; and an input auxiliary device. The input auxiliary device includes: a frame including a first holding piece and a second holding piece configured to hold one side and another side of the body, respectively, to mount the frame on the top; and a key unit attachable to a backside of the frame. The one side includes: a card slot; and a second underside extending along the top toward the another side between the top and the card slot. The first holding piece is configured to be locked to the second underside.

Abstract: According to an aspect of the present invention, there is provided a DC-DC converter including a high-side transistor, a low-side transistor, a first current detector, a second current detector and a driver. The first current detector monitors a first current flowing through the high-side transistor and outputs a first control signal when the first current becomes smaller than a first reference value. The second current detector monitors a second current flowing through the low-side transistor and outputs a second control signal when the second current becomes smaller than a second reference value. The driver turns on the low-side transistor based on the first control signal and turns on the high-side transistor based on the second control signal.

Abstract: In a method of cleaning a fluorine-containing waste gas evolved frm a furnace, by contacting said gas with a fluorine-reactive powder and filtering the fluorine-reactive powder by a filter, an improvement comprising cooling the waste gas to 150.degree.-400.degree. C; feeding a fluorine-reactive powder into the cooled waste gas; passing the cooled waste gas through a filter on which the fluorine-reactive powder is deposited so as to react with the fluorine component of the waste gas; and removing the deposited powder layer from the filter.
