Title: Method of prevention of slip or skid of electric pulling vehicle together with use of said method in detection of slip or skid of said vehicle and measurement of adhesive power
Inventor: TEIERII JIYOBAARU
IPC: B60L15/28
Filed: 1990-11-08
Abstract: PURPOSE: To prevent idling or skid of an electric traction vehicle by an arrangement wherein the control parameters obtained at the output of a servo control are limited permanently by ideal values for the control parameters. CONSTITUTION: Duty factor α of a chopper is determined by controlling the torque or the induction current according to an input target value and the ratio is limited to an ideal value. The ideal value of duty factor α provides a current required by a motor at the time of rotating at a speed corresponding to the reference speed Vref of a vehicle. When a minimum duty factor is kept for the chopper during high speed brake operation and the current I is controlled only through excitation, a theoretical value Ifth is employed as the induction current. The theoretical value Ifth is calculated from the theoretical value of flux according to the characteristic value of the motor by calculating the theoretical value of electromotive force and then calculating the theoretical value of flux.

Filed: 1989-11-22
Abstract: PURPOSE:To specify an off-hook extension quickly by constituting a gate means so that it is individually controlled by a ring relay control signal for an extension telephone set. CONSTITUTION:Gate means 4a are configurated so that they are individually controlled by a ring relay control signal Ri for extension telephone set and an output signal Re of a hell signal reply sensing section 8 is sent to each control section 10 for each extension telephone set only when the ring relay control signal Ri is logical H, that is, when a bell signal generating means 7 is operated. Thus, the control section 10 outputs the ring relay control signal Ri comprising plural signals whose level is sequentially logical H to each extension individually, resulting that the control means 10 scans the extension group and from which extension the signal representing off-hook from the bell signal reply sensing section 8 is inputted is checked. Thus, the control section specifies the extension reached to the hook-off state when the signal from the bell signal reply sensing section is received.
