摘要:
A method for manufacturing cold rolled, nondirectional electrical steel sheets and strips having a high magnetic flux density wherein a molten steel is solidified to obtain a slab in a manner that columnar grains develop predominantly from the surface in the direction of thickness of the slab up to a depth of more than 50%; said slab is heated to a temperature above 1000.degree.C without cogging and rolling to form .gamma.-phase at least more than about 10% of said slab, and hot rolled strongly with a draft of more than 98% without reheating to obtain a hot rolled steel sheet; and said hot rolled steel sheet is cold rolled with a draft of 64 - 84%, heated with a heating velocity of more than 1.6.degree.C/sec., and annealed at a temperature of 600.degree. - 1200.degree.C.

An atomization roasting furnace for producing ferrite raw material powder includes an elongated roasting furnace body with a center burner located at the top end thereof. At least three liquid spray nozzles are located in an expansion slope portion below the center burner circumferentially with respect to the center burner. A quencher, located below the elongated roasting furnace body, has a top end connected to a bottom end of the elongated roasting furnace body. Quencher nozzles are located adjacent the top end of the quencher.

Disclosed herein is a printer with a sheet feeding apparatus having a printer body incorporating a printing mechanism for printing onto continuous forms. A cutter is provided close to a continuous forms discharging port on the printer case. Following the cutter downstream, there is provided a sheet feeding belt that rotates at a rate higher than the feed rate of the continuous forms. Along the belt, there are provided a sheet traversing section, a sheet direction changing section, a sheet pushing section and a sheet stacker, in that order from upstream to downstream. The sheet traversing section seizes and feeds horizontally each sheet cut by the cutter. The sheet direction changing section perpendicularly changes the feed direction of each cut sheet. The sheet pushing section pushes each sheet onto the sheet stacker where an orderly stack of sheets is formed.

This invention provides an atomization roasting method which can easily obtain a soft ferrite sintered body, for example, a sintered body having a crystal particle size of not greater than 2 .mu.m, by using as a raw material an ultra-fine powder having a mean particle size of not greater than 0.1 .mu.m obtained by atomization roasting and which can obtain a soft ferrite raw material powder subjected to an oxidation reaction, having an extremely small residual chlorine content, and having and extremely small deviation of high vapor pressure components such as zinc between the atomized raw material solution and the oxide as the product and which can economically produce a soft ferrite core having an excellent power loss characteristic in a high frequency range, particularly in a MHz range, and is extremely effective for reducing the size of a high frequency transformer. In the production method of the soft ferrite raw material powder, the deviation of the recovered powder becomes extremely small and residual hydrogen chloride and chlorides can be reduced. Therefore, loads to the component adjustment step after roasting and to the Cl removing step can be reduced and process steps can be eliminated. Accordingly, the present invention can drastically reduce the cost of production and can improve quality.

A can end double-seaming machine has a housing in which a shaft is rotatably supported. The shaft with a seaming cam lever mounted is pressed downwardly by a presser against the bias of a spring until the lower surface of the seaming cam lever is held against the upper surface of the housing. Then, an annular spacer is fitted over the lower end portion of the shaft underneath, with the tubular support held against a neck of the shaft. A seaming roll lever is then mounted on the lower end portion of the shaft. The presser is deactivated to release the shaft, which is lifted together with the seaming cam lever, the annular spacer, and the seaming roll lever under the bias of the spring until the marginal portion of the annular spacer abuts against the lower surface of the housing. The tubular support enters the housing by a distance corresponding to a predetermined clearance. The seaming cam lever and the housing are now spaced from each other by the predetermined clearance.

A label printer for printing an image on a plurality of labels attached to a base sheet and issuing the labels on which the image has been printed. The label printer includes a platen roller, a pinch roller adapted to separably contact the platen roller through the base sheet, a slide frame for supporting the pinch roller so that the pinch roller is movable between a contact position and a separate position with respect to the platen roller, and a frame stopper for releasably holding the slide frame in the contact position where the pinch roller is in contact with the platen roller. When the frame stopper is released from the slide frame, the slide frame is slid to reach the separate position to widely separate the pinch roller from the platen roller. Accordingly, the base sheet can be easily inserted through the space defined between the platen roller and the pinch roller separated therefrom.

A can end double-seaming machine has a seaming head vertically movably mounted on a base and supporting a seaming chuck and a seaming roll. The seaming head is guided for its vertical movement by support posts on the base. Rotors are rotatably threaded on the support posts and rotatable by a motor for lifting and lowering the seaming head. A controller controls the motor to elevate the seaming head upwardly of a predetermined seaming position, then lower the seaming head downwardly of the seaming position, and thereafter elevate the seaming head to the seaming position, thereby positioning the seaming head in the seaming position. Since the seaming head is lowered downwardly of the seaming position and then lifted back to the seaming position, the seaming head is reliably and accurately be brought into the seaming position without a positional error which would otherwise be caused by the backlash between the rotors and the support posts.

The present invention is provided with a head pressing mechanism for pressing a thermal head against a platen, a paper feeding mechanism for feeding print paper between the thermal head and the platen in a secondary scanning direction, a ribbon transporting mechanism for transporting an ink ribbon between the thermal head and the platen in the secondary scanning direction, and a press releasing mechanism for causing the thermal head to move away from the platen against a pressing force of the head pressing mechanism. The press releasing mechanism slides a rod of a solenoid, elongated in the secondary scanning direction, at the position opposing to the rear surface of the thermal head in the secondary scanning direction. A lever link transforms this sliding action into the departing action of the thermal head from the platen. The solenoid and the thermal head are longitudinally aligned substantially in parallel to each other, and the area occupied by the thermal head and the solenoid is reduced, thereby resulting in a thermal printer which is compact as a whole.

Disclosed herein is an auxiliary equipment for removing parts including a cover feed turret, which has been vertically detachably installed by a screw member on a can end double-seaming machine for seaming a can end on a can body, from the double-seaming machine, or installing such parts on the double-seaming machine. The auxiliary equipment comprises a swinging member supported below the cover feed turret and horizontally swingable to under a screwing position of the screw member; the first pedestal replaceably positioned on the swinging member, on which the cover feed turret can be placed when the swinging member is swung to the screwing position of the screw member; and the second pedestal replaceably positioned on the connecting member, on which a cover guide can be placed. The swinging member and first pedestal are each provided with an operation hole through which the screw member can be operated by an operating tool through the swinging member and first pedestal from below the swinging member and first pedestal when the swinging member and first pedestal are swung to a position under the screw member.
