Title: Lead falling detection circuit
Inventor: ICHIKAWA MASAMITSU
IPC: B43L13/00
Filed: 1990-09-07
Abstract: PURPOSE:To prevent the erroneous operation due to the reduction of the light power of an optical sensor or temp. change by outputting the comparison result of the threshold value obtained by integrating and dividing the output of the optical sensor with the output of the optical sensor as a lead falling detection signal and holding threshold voltage by a holding circuit when the lead falling detection signal becomes active. CONSTITUTION:When a lead is supplied to a cartridge from a lead tank, the output of a photointerruptor 31 falls to a low level and the detection output VS inputted to a comparator 52 also falls to a low level. Since the threshold voltage VTH being the other input of the comparator 52 is obtained by integrating the detection output VS, the detection output VS is lower than the threshold voltage VTH and the lead falling detection signal VD, being the output of the comparator 52 becomes active (low level). Whereupon, the switch 50 of a holding circuit 47 becomes an OFF state and the holding circuit 47 becomes a holding state and the voltage immediately before holding held to a condenser 51 is supplied to the comparator 52 as the threshold voltage VTH. This threshold voltage VTH is held to a constant value until the lead falling detection signal VD rises to a high level.

Title: Method for controlling output of welding power source
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/12
Filed: 1984-11-12
Abstract: PURPOSE:To obtain a wire tip easy to start welding by supplying power when short circuit is detected after transmission of wire feed stop, and when non-short circuit is detected, cutting off power supply if the detected voltage between the wire and base metal becomes larger than the set value. CONSTITUTION:After outputting a stop signal to a wire feeding motor 2, if short circuit, short circuit current corresponding to an output set value is supplied to a wire 1, that is, a feeding tip 3, and if non-short circuit, a set voltage value and detected voltage value between the wire 1 and base metal 4 obtained by a voltage detector 8 are compared. Output of a welding power source is cut off when the detected voltage value becomes larger than the set voltage value. Thereby, the part of wire 1 fed by inertia is transferred to the base metal 4 as droplets by normal short circuiting transfer without cutting off output immediately after stopping of power supply to the wire feeding motor 2. When rotation of the feeding motor by inertia nearly comes to a stop, the set voltage is no more maintained and the wire 1 burns. Output is cut off immediately when short circuit occurs no longer. Thus, droplet at the tip of the wire 1 is removed.

Filed: 1990-09-07
Abstract: PURPOSE:To allow recording and reproducing in the same manner on both surfaces by building two pieces of initial auxiliary magnetic field Hini impressing means which are reverse in the direction of magnetic fields from each other in the cartridge. CONSTITUTION:This cartridge 11 of the magneto-optical recording medium contains the overwritable magneto-optical recording medium 20 of a both-side type. Two pieces of the initial auxiliary magnetic field Hini impressing means 22, 26 which are reverse in the direction of magnetic fields from each other are built in this cartridge 11.

Abstract: PURPOSE:To improve the operating efficiency of an incoming call transfer service device without invalid connection processing by implementing busy tone connection in the incoming processing process so as to avoid invalid connection processing without connecting an incoming call when a subscriber of an incoming transfer start state is busy to a 2nd terminal for the transfer connection processing. CONSTITUTION:When a subscriber 1 makes a transfer start request and dials, a line processing unit 7 receives transfer subscriber dial information representing the dialing of a subscriber in the transfer start state and an accommodated location number of a connected dial circuit 4 through the scanning of a connection control section 6. When a call comes from the incoming circuit 5 while the subscriber 1 is busy, a line processing unit 7 receives an incoming telephone number via the connection control section 6 to confirm that the 4 number is a number of the subscriber 1 receiving the incoming call transfer service and does not send connection information to a 2nd terminal but sends the information for busy tone connection to the connection control section 6. The connection control section 6 applies the control to send a busy tone from the incoming call circuit 5.
