摘要： A leakage inspection method and apparatus having a pressure wave generating means, including an air supply source, a regulator, and a solenoid valve. A pressure wave of a fluid is applied to a normal flow path of an measurement object by the pressure wave generating means to detect internal leakage by measuring, by means of a microphone, a difference between the transfer time during which the pressure wave passes through the normal flow path and the transfer time during which the pressure wave passes through the leakage flow path. Accordingly, the internal leakage of the fluid, flowing in the leakage flow path bypassing the normal flow path of an equipment having a partition and the normal flow path separated by the partition, is detected, if any.

摘要： A continuously-fed flat tube is cut into sub tubes each having a given length. The flat tube has multiple ports therein. A pair of roller cutters are enabled to follow the flat tube at a zero relative speed between the roller cutters and the flat tube. The roller cutters are moved across portions of the flat tube respectively to cut the flat tube while the roller cutters are enabled to follow the flat tube at the zero relative speed. At least one of the roller cutters enters the flat tube by a depth equal to or greater than a half of a distance between outer flat surfaces of the flat tube while the roller cutters are moved across the portions of the flat tube.

摘要： According to the present invention, a brake unit is disposed at a side of the forward direction of the fin material from a reforming unit. The brake unit contracts the fin material so that the adjacent folded portions contact with each other while being reformed. Thus, the contracted fin material is in a stable state not to be deformed easily. In this way, even if moment tilting flat portions of corrugated fin is given by the reforming unit, the flat portions are prevented from tilting. A concave or convex deformation of the folded portions can be reformed satisfactorily.
摘要翻译：根据本发明，制动单元从重整单元设置在翅片材料的向前方的一侧。制动单元使翅片材料收缩，使得相邻的折叠部分在重新变形时彼此接触。因此，收缩的翅片材料处于不易变形的稳定状态。以这种方式，即使由重整单元给出波纹状翅片的平坦部分倾斜的力矩，防止平坦部分倾斜。可以令人满意地改变折叠部分的凹凸变形。
