Abstract: An information collecting unit reads encoded moving image data from an information storing unit, decodes part of the moving image data, extracts the number and the magnitudes of motion vectors, the square measure of a region having a low correlation with a preceding/succeeding frame, etc. for each frame, and outputs these items of scene change information to an evaluation function calculating unit. The evaluation function calculating unit calculates the value of a predetermined evaluation function based on the scene change information, and outputs the calculated value to a scene change determining unit. The scene change determining unit determines a frame of a scene change by making a comparison between the calculated value and a threshold value. A scene change information storing unit stores the scene change information used for the determination.

Abstract: A slide mechanism of a portable device and a portable telephone comprising such a slide mechanism is provided for a semi-automatic opening and closing with a simpler structure, as well as for an opening and closing with an improved operability.

Abstract: In a data erasing method of a nonvolatile semiconductor memory device, cells are subjected to the processings of executing programming by applying a voltage to the cells to set their threshold values at a given level or more, erasing the cells to set their threshold values at a lower level or less, executing weak programming once on a cell whose threshold value is lower than a further lower level, by applying a lower voltage to the cell, repeating the weak programming on the cell when its threshold value is still lower than the further lower level, until the value reaches the further lower level or more, verifying whether a cell is present whose threshold value is higher than the lower level, and returning the processing to the processing of setting the threshold values of the cells at the lower level or less, when verifying that the above cell is present.

Abstract: A fuel injection valve has: a tubular body, a valve seat member, a valve body, a core tube, a bias spring, and an electromagnetic actuator. The core tube is press fitted into the tubular body. The core tube has a first end side opposing an absorption section of the valve body in such a manner as to form an axial gap interposed between the first end side of the core tube and the absorption section. The core tube has a second end side axially extending in the tubular body to a certain position on a way to the second end side of the tubular body. The axially extending second end side of the core tube has an outer periphery which is formed with a reduced diameter section for increasing an accuracy in positioning the core tube when the core tube is press fitted into the tubular body.

Abstract: The time required for the program verify and erase verify operations can be shortened. The change of threshold values of memory cells can be suppressed even if the write and erase operations are executed repetitively. After the program and erase operations, whether the operations were properly executed can be judged simultaneously for all bit lines basing upon a change, after the pre-charge, of the potential at each bit line, without changing the column address. In the data rewrite operation, the rewrite operation is not effected for a memory cell with the data once properly written, by changing the data in the data register.
