Abstract: An information processing apparatus, including circuitry configured to transmit a start instruction to a first camera apparatus and a second camera apparatus. The start instruction causes the first camera apparatus to start incrementing a first counter and the second camera apparatus to start incrementing a second counter for a video recording time period. The circuitry receives, from the first camera apparatus, a first recording-start frame identifier that indicates a value of the first counter and a second recording-end frame identifier that indicates the value of the second counter. The circuitry receives, from the second camera apparatus, a first recording-start frame identifier that identifies a value of the second counter and a second recording-end frame identifier that identifies the value of the second counter.

Abstract: A method for producing a steel tube of high strength and toughness for air bag subjects a steel tube to high-frequency induction heating such that the outer surface temperature T1 (° C.) of the tube measured at the end of high-frequency induction heating is within the range defined by TAc3+40° C.?T1?1100° C., TAc3 is the temperature (° C.) of Ac3 transformation point. Using the measured outer surface temperature of the tube, time x (second) elapsed from when the outer surface temperature of steel tube reaches the temperature of Ac3 transformation point by high-frequency induction heating is calculated. Based on the calculated time x, time t (second) required from measurement of the outer surface temperature of steel tube to the start of rapid cooling is controlled so that the time t is within the range defined by 0 (sec)<t?10 (sec)?x.

Abstract: There is provided a method for straightening a steel product, comprising using hard alloy straightening rolls each made of a tungsten carbide-cobalt (WC—Co) based sintered material (hard metal), wherein the hardness of each roll is HRA85 to 87. According to this straightening method, when bends of steel product are straightened, roll wear is suppressed, defective roll mark(s) caused by the roll wear is prevented from being formed on the surface of the product being straightened, and time for changeover and/or setup of rolls is shortened to enhance the operation rate of the straightening machine, whereby the efficiency of a finishing process and, in turn, the productivity can be improved. Therefore, this method is especially effective in the case where a product to be straightened is a high-strength product such as a steel pipe for a motor vehicle air bag.
