摘要： PURPOSE:To manufacture the parallelly joined alloy having high cleanliness by forming a stock by joining two kinds of different metals, cutting a prescribed range containing a joined part on the surface of the stock extending over prescribed depth, and rolling the stock to a prescribed specification. CONSTITUTION:In order to operate more largely and exactly a bimetal function of a parallelly joined alloy, it is necessary to make a weld fusion cross sectional area small, and high energy heat source welding is executed as its means. As for a bimetal stock which is brought to parallelly joining welding 21, skin pass rolling 22 of the next process is executed, and by applying light pressure, deformation of a weld zone and unevenness of a molten part are eliminated. By surface grinding 23, a residual spatter, an adhesion spatter, etc., at the time of welding are eliminated, and cleanliness of the surface is improved. As for the means for surface grinding, surface grinding is selected, and a part in which an adhesion foreign matter exists is brought to local grinding whose specific depth is the upper limit. Finish rolling 24 is cold rolling for enhancing the rigidity of a product of the bimetal stock. In such a way, the adhesion spatter is eliminated, and a parallelly joined alloy being free from foreign matter adhesion can be manufactured easily.

摘要： PURPOSE:To prevent the increase of a damage due to an accident by detecting the presence or absence of an AC ripple component of a zone during power supplying, thereby identifying whether it is during the power supplying or not and controlling regenerative brake. CONSTITUTION:When an electric rolling stock is regeneratively braked, a regenerative current (i) flows through a current collector 6 to a trolley wire 3. An AC current transformer 7 for detecting the AC component of the current (i) is arranged at the suitable position of a trolley line circuit at the side of the rolling stock. A frequency component detector 8 identifies whether the component of the frequency generated by the power supply of a substation exists or not in the AC current detected by the transformer 7, and when such frequency component does not exist, an output corresponding to it is immediately fed to a controller 11, which stops the regenerative brake operation. In this manner, the regenerative brake of the rolling stock can be automatically stopped in a no power supply zone.

摘要： PURPOSE:To enhance the regeneration effective rate by detecting a trolley voltage and a travelling ground point and suitably switching operation modes. CONSTITUTION:A deceleration characteristic curve reader 4 and an operation mode switching ground point characteristic curve reader 5 input signals from a travel station discriminator 2 and an integrated mean trolley voltage detector 6, and read deceleration beta1, power notch-off point P1 in the station and a brake starting ground point B1. An operation mode switching command generator 3 applies a notch-off command to a vehicle controller 9 when the travelling ground point from a train travelling ground point detector 1 coincides with the power notch-off signal, and applies a brake start command and the deceleration B1 to the controller 9 when the travelling ground point coincides with the brake start ground point signal B1. In this manner, the best regeneration effective rate can be obtained.
