Inventor: MATSUMOTO MINORU
IPC: F16L27/12
Filed: 1982-10-18
Abstract: PURPOSE:To prevent separation of an expansion pipe fitting and thereby enhance the safety by employing a divided retainer ring, in which a lock ring part and a retainer ring part are embodied in a single solid construction, and by allowing the retainer ring itself to work also with joining function. CONSTITUTION:A retainer ring 13 has a profile including a lock ring so as to be fitted in a groove 10, being divided in a plurality of segmented pieces, where the two ends of any one or more of those segments 14 are parallel.

Abstract: PURPOSE:To realize a stabilized control by employing signals, each having a pulse width increasing or decreasing by an integral multiple of a minimum unit width, as the control signals for the input voltage to the primary winding and the voltage induced in the secondary winding. CONSTITUTION:An FET Q1 is switched by a PWM1 signal from a PWM control circuit 101 to induce a voltage V2 in the secondary winding N2. The voltage V2 is then divided through a voltage division circuit W1 and applied to an FBINI terminal. The level of divided voltage is determined for every output pulse of the PWM1 signal and the pulse width thereof is increased or decreased by a multiple of minimum width based on the level thus determined. On the other hand, an FET Q2 and a transistor Q3 are switched based on PWM signals from a PWM control circuit 104 and a synchronism detection circuit 103 to induce a voltage V1 in the secondary winding N3. The voltage V1 is then divided by resistors R3, R4 and the level of divided voltage is determined. Subsequently, the pulse width of the PWM signal is increased or decreased by an integral multiple of the minimum unit width based on the determined level thus realizing a stabilized control.
