摘要： In a driving mechanism of a circuit breaker having first and second hydraulic operation apparatuses respectively driving a main contact and a resistor contact, a sequential control valve is provided between the first and second hydraulic operation apparatuses. The sequential control valve detects the operation of a differential piston for opening the main contact and switching the differential piston for sequentially opening the resistor contact after the opening of the main contact.

摘要： A hyaluronic acid-containing aqueous solution or aqueous dispersion of collagen having a pH of from about 6.5 to about 8.0 and an osmolality of from about 230 to about 320 mOsm/kgH.sub.2 O. The aqueous solution or the aqueous dispersion of collagen is useful as an agent for correction and reparation of a depressed part of or a void in soft tissue of mammals.
