This manufacturing method of a grain-oriented electrical steel sheet is a manufacturing method of a grain-oriented electrical steel sheet having no forsterite film, in which in a decarburization annealing process, a cold-rolled steel sheet is (i-1) heated at an average heating rate (HR1) of 40 to 500° C./sec in a temperature range of 550° C. or higher and lower than 720° C., (i-2) heated at an average heating rate (HR2), which is 5 to 50° C./sec, in a temperature range of 720° C. to T1° C. (770° C.≤T1 (° C.)≤900° C.), and (ii) retained at the temperature of T1° C. for 50 to 1000 seconds to make an amount of C 25 ppm or less in an atmosphere of an oxygen partial pressure (P1) which is 0.0010 to 0.20.

Control apparatus and control method

A vacuum packaging method and apparatus for packaging solid objects such as food products of various shapes automatically. A web of tubular plastic film is supplied from a roll and drawn over an opening core which opens the plastic film into a rectangular shape. The film is then drawn over the object to be packaged and cut to a predetermined length. In one embodiment, the front end of the film is then sealed and the object urged towards the sealed end. In another embodiment, both ends of the film are left open at this point. The object with the film positioned therearound is transferred to a vacuum chamber. Prior to the chamber being evacuated, tension is applied to the film so as to prevent the formation of creases.

Automatic continuous vacuum packaging method and apparatus

While conveyed along a deck plate of the apparatus, a smoked ham is conveyed toward a side of the deck plate to have an outer end of an ear of smoked ham casing sandwiched by a sandwiching conveyer, a shoulder of the smoked ham is then pushed by a first guide portion of a guide so that a ligating fitting of the smoked ham casing may be pulled out of a base of the ear, in succession thereto is extended a gap between the ligating fitting and the shoulder by a second guide portion of the guide, and thereafter the base of the ear is cut off by a cutter which occupies a position relative to that of the guide. Therefore, the ear of the smoked ham casing can be accurately cut off at a predetermined position.
