    摘要: An electric heating unit comprises a heat-insulating main body consisting primarily of a heat-insulating material and formed with a groove in a surface thereof, and a heating element provided in the groove and shaped in the form of waves with an amplitude greater than the width of the groove, the heating element having at widthwise opposite sides thereof bent portions extending into the main body from groove-defining opposite side walls thereof and thereby integrally supported by the main body. A bottom-forming member of refractory material made separately from the main body covers the bottom of the groove and is supported by the main body integrally therewith so that the surface of the member toward the opening of the groove is exposed from the main body. The heating element is disposed closer to the groove opening than the bottom-forming member and integrally supported by the main body so as to be in contact with portions of the surface of the member. The heating element is positioned within the groove and exposed outside the main body.

    摘要: A vertical spindle duplex head for a grinder includes an annular pressure wheel and a receiver wheel arranged to rotate and revolve workpieces between the annular surfaces of the pressure wheel and the receiver wheel and a grindstone for one end portion of the workpieces driven in the opposite directions of rotation of the pressure wheel and receiver wheel and at their different rotational ratios. The workpieces rotate and revolve between these wheels, thereby grinding their end face by means of a grindstone arranged around the external periphery of a rotary carrier.The pressure wheel and receiver wheel are rotatably driven in opposite directions and at their different rotational speeds by distributing driving force from one source to each of them and a variable driving means is provided on one of the transmittance routes of the driving force extending from the place of distributing the driving force to both of the pressure wheel and the receiver wheel, whereby the rotational ratio of each of them can be optionally changed.
