  • Method of manufacturing head suspension for disk drive
    Patent number: 7124496
    Abstract: A head suspension for a disk drive has a base plate (19) to be attached to a carriage of the disk drive and a load beam (21) consisting of a rigid part (27) and a resilient part (29), to apply load onto a slider. The rigid part and resilient part are separately formed. The rigid part is joined to a first side (29a) of the resilient part. The suspension also has a reinforcing plate (37) to hold and fix a second side (29b) of the resilient part between the reinforcing plate and the base plate. The base plate stably and resiliently supports the load beam. This suspension satisfies required characteristics.

  • Device and method for pressure control of cargo tank of liquefied natural gas carrier
    Patent number: 6901762
    Abstract: An apparatus for controlling the pressure in a cargo tank 1 supplies BOG generated from liquefied natural gas stored in the cargo tank 1 to a burning system 6 through a compressor. In this apparatus, a reliquefaction plant 5 is disposed on the downstream side of first and second compressors 3 and 4 and on the upstream side of the cargo tank 1 so that BOG discharged from the second compressor 4 is liquefied by the reliquefaction plant 5 and the liquefied fluid is returned again into the cargo tank 1.
