Title: Auxiliary power supply circuit for high voltage transformer
Inventor: NARASAKI TOSHIO
IPC: H04N3/185
Filed: 1989-02-13
Abstract: PURPOSE:To shorten a carrier storage time and to improve responsiveness to a control signal by providing a diode for reverse current and making a current, which flows from the upstream side of a transistor for control to a downstream side, flow through this diode for reverse current. CONSTITUTION:When an output end T4 of a coil 102 for auxiliary voltage generation goes to be -several hundreds V, the current flows from a voltage doubler circuit 106 through a diode 202 for reverse current to the coil 102 for auxiliary voltage generation. Accordingly, the current from a base 104b to a collector 104c of a transistor 104 for control is not generated. Thus, a carrier is not replenished in the collector area of the transistor 104 for control and the carrier storage time can be widely shortened. When the control signal is turned off in a transformer 108 for control, the transistor 104 for control can be speedily turned off.

Title: Tool path data generating method
Inventor: SUZUKI YUTAKA
IPC: G05B19/4093
Filed: 1994-03-03
Abstract: PURPOSE:To generate the moving path data of a high accuracy tool, corresponding to a spring tool, in a short time by generating the copying displacement of the tool in the normal direction to the surface of a model, and generating the moving path data of the tool in such a way that the tool moves in the right-angled direction to the copying displacement. CONSTITUTION:The model shape data corresponding to a workpiece, tool shape data and the machining range and machining pattern of the workpiece are set and inputted to a computer. A tool is made to approach to copy a model on the computer, and the tool reference point coordinate of the tool in the contact state is computed from the copying displacement of the tool at the time of the tool biting into the model and set as a machining starting tool position. The tool is then moved in the right-angled direction, and whether the tool is in the biting state is discriminated for corrective operation. The point sequence of the correctively computed tool reference points are connected to generate the data of a tool moving path for output. The data can be therefore generated in a short time.
