  • Equipment for producing corrugate fin
    Patent number: 7340935
    Abstract: The equipment for producing a corrugate fin is capable of forming corrugated sections by one closing action. The equipment comprises: a plurality of punches respectively having projections, each of which is upwardly projected from an upper face of the punch and has a side slope face; a pair of cam blocks being capable of relatively moving close and away each other, the cam blocks respectively having pressing sections, which are capable of moving along the side slope faces and contacting the projections; and a cam plate relatively moving the cam blocks close or away each other. Positions of the side slope faces of the projections are different so as to make the pressing sections contact the projections in order, and the cam blocks move the punches toward the die in order by one closing action of the blocks.

  • Backup memory control unit with reduced current consumption having normal self-refresh and unsettled modes of operation
    Patent number: 7085946
    Abstract: A backup memory control unit can reduce the current consumption when a memory (SDRAM) is inactive by providing the memory with an unsettled mode in which no power is supplied to the memory. It provides the memory with the unsettled mode, and halts the power supply from a backup power supply to the SDRAM in the unsettled mode in which the SDRAM is not in operation, thereby limiting an increase in the current consumption. The functions are executed by a hardware circuit without using a backup microcomputer.
