  • Patent number: 8709550
    Abstract: In a process for manufacturing a coated steel sheet such as a coated electromagnetic steel sheet using a water-based coating liquid containing an organic resin, to perform steps subsequent to an annealing step continuously at high speed without causing appearance defects such as coating unevenness; to provide an electromagnetic steel sheet having an insulating film thereon, in which properties of the film are satisfactory, superior weldability and punchability can be obtained without deteriorating the space factor, and the satisfactory film properties can be maintained even if the electromagnetic steel sheet having the insulating film thereon is temper-rolled. A coating liquid is applied onto an untreated steel sheet. The applied liquid is heated on the side close to the steel sheet in such a manner that the time elapsed until the steel sheet temperature is increased to 100° C. after the application is completed is 10 seconds or less, thereby drying the coating liquid.

  • Patent number: 7995324
    Abstract: An object is providing an electrostatic attraction apparatus and an attracting/releasing method capable of reliably attracting and quickly releasing a glass substrate. An attraction force for attracting a glass substrate is obtained according to the physical properties of the glass substrate. In addition to obtaining an attraction voltage (Vc(t)) required for obtaining the attraction force, a holding voltage (Vh(t)) for holding an attraction state and a release voltage (Vr(t)) for releasing the glass substrate are also obtained (S1 to S7). Attraction time period (tc) is actually measured and if this measured time is different from a preset attraction time (t1), the holding voltage (Vh(t)) and the release voltage (Vr(t)) are recalculated according to the actually measured attraction time period (tc) (S8 to S11).
