IPC: C22F1/00
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To increase the hardness and strength of a pin without depending on the change of wire drawing conditions by wire-drawing a wire rod consisting essentially of tungsten into a prescribed shape, subjecting at least one part of the obtd. pin to carbonizing or nitriding and forming a tungsten or tungsten nitride layer.

Title: Remote supervisory and controlling equipment
Inventor: TODA TAKEO
IPC: H04Q9/00
Filed: 1985-12-27
Abstract: PURPOSE:To reduce the restriction for the distance of a transmission path and the number of branches of the transmission path by presetting the frequency of a signal transmitting from a master station to a slave station and the frequency of a signal transmitting from the slave station to the master station to different values and forming a transmission request signal based on a received signal by the master station when the master station receives the signal from the salve station. CONSTITUTION:In the case of the constitution of a pair of transmission paths as shown in the drawing, a modulating frequency is allocated to f1 (master station) and f2 (slave station) so as to discriminate whether it is the signal from the master station 10 to the slave stations 11, 12 or the signal from the salve stations 11, 21 to the master station 10. When the master station 10 detects the modulating wave f2 from the salve stations 11, 21 by a demodulator 102, it transmits the modulating wave f1 (modulating wave on which a specific signal is not mounted) to the respective slave stations 11, 21 through a modulator 101 of its own station. As a means therefore,the master station has a constitution for inputting the OR signal RSO' of the transmission request signal RSO from a transmitter T in its own station and the carrier detection signal CDO of the modulating wave f2 signal from the slave station which is detected through the demodulator 102 as the transmission request signal of the modulator 101.
