Filed: 1977-09-28
Abstract: PURPOSE: To provide the subject device wherein at the time of normal running of the DC transmission system a current set value at the usual driving is imparted to the system and at the time of trouble a current set value on which the DC becomes within the interrupting capacity is imparted thereto, thereby facilitating cutting off of the inverter in trouble.  
     CONSTITUTION: Taking notice of a fact that even the conventional DC interrupter can interrupt a DC if it is suitable, the set current for each of the inverters is lowered so that the current becomes an interruptable current, thereby to suppress to interrupt the current flowing into the troubled inverter. That is, in a multiterminal DC transmission system in which a plurality of AC-DC inverters are connected to the DC line through respective DC interrupters, a set value Idf at the trouble is provided, in addition to a set value Idp of a constant-current control circuit ACR and a current margin necessary for power inverting time, and if any inverter is in trouble, the unit receives the signal which has detected the trouble, thereby to change over to the set value Idf

Abstract: PURPOSE:To provide a fixing roller device capable of eliminating the futile consumption on of power and efficiently making use of the power by setting a contact width in a cylindrical direction where a feeder electrode comes into slidable contact with a connection electrode equal to a contact width in a circumferential direction where a resistance heating element press-contacts with a pressure roller. CONSTITUTION:In a fixing roller 1, the resistance heating element 3 is formed in a region on the outer periphery of a cylindrical substrate coming into contact with the pressure roller 6 and the connection electrodes 4 located on both ends of the resistance heating element 3 and divided in the circumferential direction Y is formed as well. The power is supplied to the feeder electrodes 5 coming into slidable contact with the connection electrodes 4 of the fixing roller 1, so that the resistance heating element 3 can generate heat. The contact width L in the circumferential direction Y where the feeder electrode 5 comes into slidable contact with the connection electrode 4 is set equal to the contact width in the circumferential direction Y where the resistance treating element 3 press-contacts with the pressure roller 6. Thus, the power is supplied only to the region of the resistance heating element 3 corresponding to a fixing region at the time of actually fixing, to heat the region. Thus, the futile use of the power is eliminated and the power can be efficiently used.

Abstract: PROBLEM TO BE SOLVED: To restrain ultrasonic damage to one surface of a substrate while covering its other surface with a liquid film to prevent particles from being restock. SOLUTION: In a method of washing a substrate in which washing liquid with ultrasonic waves is fed from a nozzle 11 to the rear of a substrate W whose surface is covered with a liquid film to wash it, washing is performed under the condition to satisfy 1<ft<5 and 34<θ<70 where the frequency of the ultrasonic waves, the thickness of the substrate W, and the incident angle of the washing liquid with the normal of the surface of the substrate W as a reference are defined as f [MHz], t [mm], and θ[ deg.] respectively.
