Abstract: PURPOSE:To easily and surely perform AM detection by synchronizing an AMWT inputted at an AMWT synchronization circuit with CODE DATA inputted from a 1-7 encoder, and performing of a prescribed pattern of AM write an at AM write circuit. CONSTITUTION:A controller 11 sends the address mark write AMWT to the AMWT syncronization circuit 14, and synchronizes it with the code data CODE DATA inputted from the 1-7 encoder 12. The address mark AM write circuit 15 perform the prescribed pattern of AM write by receiving the synchronized AMWT from the AMWT synchronization circuit 14. Therefore, the AMWT is synchronized with the CODE DATA even when the AMWT is sent at ant position of the CODE DATA in which (001) is continued, and the prescribed pattern of AM write is performed behind the CODE DATA. In such a way, it is possible to eliminate the fluctuation of the start point of a written AM pattern, and to perform the detection of the AM pattern easily and correctly.

Abstract: PURPOSE:To adjust the flow rate of refrigerant, according to a cooling state, by installing adjusting mechanism constituted of a pivotal valve which is pivotally moved by an elastic member, in a feedback channel which returns the refrigerant to a cooling equipment. CONSTITUTION:Refrigerant 10 is supplied from a cooling equipment 1 to a plurality of cooling modules 2-1-2-N, via supply channels 3, and returned to the cooling equipment 1 via feedback channels 4. Adjusting mechanisms 8 are installed in the feedback channels 4 corresponding with the cooling modules 2-1-2-N. A pivotal valve 8B which pivotally moves around a shaft 14 as the center, and an elastic member 8A which is formed by injecting liquid 12 in the hollow part 11A of a sphere-shaped elastic part 11 are built in the adjusting mechanism 8. When the temperature of the refrigerant 10 increases up to a specified value, the pivotal valve 8B operates in the open direction so as to increase the flow rate of the refrigerant 10. When the temperature decreases, the valve operates in the close direction. Hence the flow rate of the refrigerant 10 is automatically adjusted. Thereby the flow rate of the refrigerant is adjusted without installing a valve, a temperature sensor, and a control part.
