Simplification of a device configuration and control is realized, which enables attraction and release by a magnet without using a battery. A magnet work machine includes a generator motor () driven by an engine (); and an inverter () which controls a magnet () and the generator motor () such that the magnet () is energized by electric power from the generator motor () to attract metal scraps or the like, and during demagnetization for releasing metal scraps or the like, electric power applied to the magnet () is transmitted to the generator motor () as regenerative power so as to be consumed. The inverter () determines a torque of the generator motor () as a motor according to a voltage change of a main circuit based on a detected main circuit voltage so as to suppress the voltage change, and gives the torque as a command.

The present invention relates to an anode substrate for a solid electrolytic capacitor which is produced by cutting obliquely a metal substrate comprising a valve-acting metal layer having fine pores and a valve-acting metal layer without fine pores, and having a cut surface which is formed by elongation of the valve-acting metal layer without fine pores dragged by a cutting blade; particularly to an anode substrate for a solid electrolytic capacitor which is produced by cutting obliquely a metal substrate comprising a valve-acting metal layer having fine pores and a valve-acting metal layer without fine pores, and a layer of the elongated valve-acting metal which is generated by that the valve-acting metal layer without fine pores is elongated being dragged along with a cutting blade and covers the edge part of the valve-acting layer having fine pores meets the requirement represented by the following formula:0&#x2266;&#x2266;1&#x2003;&#x2003;[Formula 1]wherein y represents the thickness of the layer of the elongated valve-acting metal in the direction of the thickness of the substrate and z represents the thickness of the valve-acting layer having fine pores which is in contact with the elongated metal layer in the direction of the thickness of the substrate, respectively; and to a solid electrolytic capacitor comprising the above-mentioned anode substrate, an edge of which is chamfered at least partially.
