摘要： An automatic control type electronic flash apparatus comprises means for emitting flashlight and flashlight emission stopping means. The stopping means receives the flashlight emitted by the flashlight emitting means and reflected by an object to be photographed and stops the emission of the flashlight by the flashlight emitting means when a quantity of the flashlight received reaches a predetermined value. The flash unit includes integrating means for integrating a current corresponding to the flashlight emitted by the flashlight emitting means in place of the flashlight reflected by the object and comparing means. The comparing means compares an integrated value from the integrating means with a reference value and generates a first output when the integrated value is smaller than the reference value and a second output when the integrated value is greater than the reference value. The flash unit includes indicating means for showing an over-exposure in response to the first output.

摘要： In a memory array MCA which includes memory cells MC each having a variable-resistance-based memory device RQ and a select transistor MQ, an object is to receive a fixed quantity of storage data for a short time, and to realize writing operation to the memory cell, with suppressed peak current. In order to achieve the object, the data bus occupation time in rewriting operation is shortened by using plural sense amplifiers and storing storage data temporarily, and plural programming circuits are provided and activated using the control signals with different phases. By the above, the phase change memory system with low current consumption can be realized, without causing degradation of the utilization ratio of the data bus.

The body includes a prime mover, a fan volute chamber, a fan housed in the fan volute chamber and attached to one end of an output shaft of the prime mover, and an air inlet of the fan volute chamber formed in front of the fan. A main guard member is so mounted as to cover one side surface of the fan volute chamber on which the air inlet is formed, and a gap for radially introducing external air into the air inlet is formed between a rear side of the main guard member and the one side surface. The gap is in open communication with atmosphere at a top portion of the body. A bottom guard member connected to the main guard member and the fan volute chamber covers bottom portions of the fan volute chamber and the prime mover, and a sub-guard member connected to the bottom guard member and the fan volute chamber covers sides of the prime mover which oppose the main guard member and the bottom guard member, respectively.
