Title: Digital-analog converting circuit
Inventor: SHIRAKI RIYUUZOU
IPC: H03M1/78
Filed: 1982-05-21
Abstract: PURPOSE:To keep a small chip area and at the same time to improve the accuracy of conversion, by having a constant level for the gate-source voltage of an MOSFET which is used as a switch. CONSTITUTION:When the signal D of the highest bit is inverted into the level ''1'', an MOSFET32 is turned on. Then a current I1 flows from the input voltage VIN through a resistance 34. The same working is secured also with signals of optional bits D2-Dn, and then a digital signal is converted into an analog current. In this case, the sources of MOSFET31 and 32 which are controlled with the signal D1 are connected to the earth potential, respectively. Therefore, the gate-source voltage VGS is constant for FETS 31 and 32 despite of the variation of the reference voltage VREF and the voltage VIN. While the potential is set approximately at a constant level at the joint of a resistance 11 although it increases gradually. As a result, the voltage VGS is also set approximately at a constant level for FET31 and 32, respectively.

Title: Cut slag removing device of fusion cut slab
Inventor: NAKAMURA YASUKI
IPC: B23D1/22
Filed: 1978-07-17
Abstract: PURPOSE: To shave off cut slag from the back face by reversely feeding the slab, by inclining the cutter blade in the carrying direction.  
     CONSTITUTION: A slab 3 carried by a roller table 1 collides against the cam-shaped back face of a blade protruding from the carrying surface. As a result, the blade part 5 is turned clockwide, and inclined by a counterweight 22. When the slab 3 reaches a stopper 2, it is detected by a sensor, and a reverse feed command is issued to the roller table 1, so that the slab 3 is fed reversely in the opposite direction. At this time, since an upward pressure is applied to the blade part 5 by a compression spring 17, when the slab 3 moves reversely, it is forced to turn counterclockwise until the perpendicular position. When the cut slag 3a at the lower face of the slab 3 hits against the cutting blade 5a, the end bites into the cut slag 3a, so that the blade part 5 stands upright. Then, a supporting frame 10 of the rotary drum part hits against a stopper 23 to block the rotation of the blade part 5, so that the cut slag 3a is shaved off.
