Title: Head for vtr
Inventor: NAEMURA KOUJI
IPC: G11B5/187
Filed: 1983-03-02
Abstract: PURPOSE:To improve the contact state between a head and a tape and improve the picture quality of VTR by forming a tape run surface on a plane which runs through the center of the tape run surface and is perpendicular to the relative sliding direction of the head symmetrically about an axis which runs through the center of the tape run surface and is perpendicular to the tape run surface. CONSTITUTION:The shape of the tape run surface when cut by the plane 8 perpendicular to an (x) direction in the direction of the relative slide between the tape 5 and head 1 is shown by a solid line 9. The part of the tape run surface in the cut surface of the head shown by the solid line 9 is symmetrical about an (y) axis. The surface shape of the tape run surface 8 on the said plane 8 is symmetrical about the height-directional axis of the head 1 which crosses the (x) axis, i.e. (y) axis in standard video recording and reproduction mode. Therefore, pressing force which operates on the tape 5 on the tape run surface 3 is symmetrical about the (y) axis in an operation state and the magnetic tape 5 deforms symmetrically about the (x) axis near the tape run surface 3. Consequently, the contacting state between the tape run surface 2 and tape 5 is improved to improve the picture quality of VTR.

Inventor: KANEKO TETSUAKI
IPC: H03K17/725
Filed: 1984-02-28
Abstract: PURPOSE:To discriminate surely the operating state at no load and a fault of an element by inputting an output signal of a voltage detector connected between an anti- series connecting point of a bipolar semiconductor circuit breaker and a connecting bus of a power and a load and an open/close command signal of the bipolar semiconductor circuit breaker so as to detect the operating state of the bipolar semiconductor circuit breaker. CONSTITUTION:When the bipolar semiconductor circuit breaker 11 is brought into the non-conductive state while a current flows from a DC power supply 1 to a load 3 and from the load 3 to a regenerative inverter 9, since an output of a voltage detector 12 is zero when the semiconductor circuit breakers 2, 2a are normal, the non-conductive state is detected by comparing the output with an open/close command at an operating state detection circuit 7. When the load current is zero and the bipolar semiconductor circuit breakers are opened by the open/close command, and if an element fault of the 1st semiconductor circuit breaker 2 and interruption fault take place, the voltage detector 12 detects the voltage of the DC power supply 1, and while an element fault or interruption fault of the 2nd semiconductor circuit breaker 2a takes place on the other hand, the voltage detector 12 detects a cunter electromotive force of the load 3.
