In order to evaluate the welding current for the resistance seam welding of an overlap seam of container bodies, a welding with changing welding current intensity is carried out for a container body of the production series, resulting in a changing welding of the seam, ranging from the welding with a too high temperature to the welding with a too low temperature. The electric energy for this welding is determined several times during this welding and / or the temperature of the weld seam is determined several times and the welding current intensity is determined at which the welding of the individual container body is too cold and the welding current intensity at which the welding is too hot. This determination is based on the determined electric energy values and / or on the determined temperature values and based on this determination a preferred range for the welding current intensity within these limits of too hot and too cold is determined. By this, an evaluation if the welding current intensity is correct may take place in a simple way during the production. After the welding of the individual container bodies a changed welding current intensity lying between the welding current intensity of the too hot and of the too cold welding may optionally be set and used for the following series of container bodies of the production series.

Alternation processes reduce the recording and reproducing speed of a hard disk apparatus.A hard disk apparatus comprising: an HDD 10 for recording AV data onto a hard disk; and stream controlling means 8 which is connected to the HDD 10 and thereby processes the signal of AV data transmitted from an IEEE1394 I / F 7 or the signal of AV data transmitted to the IEEE1394 I / F 7; whereby the hard disk apparatus can record and / or reproduce the AV data, wherein when AV data transfer is not normally completed for a disk access unit which is a minimum continuous unit in the access to the hard disk, an alternation process on a disk access unit basis is carried out so that another disk access unit is used hereafter in place of that disk access unit.

The invention relates to a boat-type semi-continuous method for preparing boron nitride nanotubes and a method for using the same. The set of equipment includes an electric temperature control heating device A, a furnace body B, a furnace head C and a furnace tail D. The electric temperature control heating device A is used to adjust and control the temperature of the furnace body B. The furnace in the furnace body B passes through the furnace tube and the two The furnace head C on the side is communicated with the furnace tail D, and a circulating water holder for cooling is arranged on the outer surface of the furnace tube. The raw materials react with ammonia gas in the furnace chamber of the furnace body B, and then are transferred to the furnace tube between the furnace body B and the furnace tail D for cooling. At the same time, the next batch of raw materials are transported to the furnace chamber for reaction. The furnace tail D is taken out, thereby realizing continuous production. The device has the advantages of convenient operation, rich and diverse product structures, and is especially suitable for industrial production applications. It has high equipment safety and good stability, and can continuously synthesize BNNTs with different structures on a large scale.
