An electron device such as a fluorescent display tube is provided, wherein a simple ring-less getter can be simply fixed and arranged with a large degree of freedom. The ring-less getter, G11 to G13, is securely fixed to the inner surface of the glass anode substrate 111, using laser beams. The laser beam is irradiated onto the ring-less getter, G11 to G13, from outside the anode substrate 111. Thus, the laser beam passes through the anode substrate 111, thus heating and melting the ring-less getter, G11 to G13. The corresponding inner surface of the anode substrate 111 is melted trough the heating. In cooling, the portion where the ring-less getter, G11 to G13, and the anode substrate 111 are in a molten state is solidified, so that the ring-less getter, G11 to G13, is bonded to the anode substrate 111. The ring-less getter, G11 to G13, is shaped arbitrarily through press-working a getter material.

A controlled compressor apparatus enables a hybrid compressor in an idle-stopping vehicle to operate more efficiently when driven by a motor alone. The controlled compressor apparatus includes a compressor 110, included in a refrigeration circuit 200, of a variable volume type for compressing a refrigerant; a motor 120 powered by a battery 12 to operate; and a controller 130 for selecting the driving force provided either by the engine 10 or the motor 120 to drive the compressor 110 and control its discharge volume. The controller 130 causes the motor 120 to operate the compressor 110 such that the compressor 110 is turned on or off at a discharge volume of the compressor 110 that larger within a variable range than that required for operating the refrigeration circuit 200.
摘要:
A fluorescent display device of the plane grid type capable of reducing accumulation of charges on an insulating layer, to thereby prevent an electron shading phenomenon and permit electrons emitted from a filament toward anode electrodes to be uniformly spread in a plane-like manner on both sides of the filament. A first substrate is formed thereon with stripe-like thin-film anode electrodes and stripe-like thin-film grids in a matrix-like manner through a thin-film insulating layer. The insulating layer and grids are formed with openings. Phosphors are deposited on portions of the anode electrodes exposed through the openings. The grids are formed into a height equal to or smaller than that of the phosphors. A second substrate is formed thereon with back electrodes for controlling emission of electrons from filaments. Control voltages applied to the back electrodes have a potential gradient given thereto so that a potential difference occurs between a position near the filaments and a position apart therefrom.

The invention is a bottle-shaped can manufacturing method of shaping a neck portion, a shoulder portion and a body portion integrally. The method comprises: a step of shaping a covered metallic sheet, as prepared by forming thermoplastic resin covering films on the two surfaces of a metallic sheet and by applying a lubricant to the thermoplastic resin covering films, into a cup shape by punching out the metallic sheet; a step of shaping the shaped cup into a bottomed cylindrical can reduced in diameter and thinned at its body portion; a step of shaping the bottom side of the bottomed cylindrical can into a shoulder portion and an unopened neck portion; a step of removing the lubricant at least from the outer surface of the can which is not opened at its neck portion but opened at the lower end of its body portion; a step of applying a printed design to the outer surface of the body portion cleared of the lubricant; and a step of shaping a cut end portion, as opened by cutting the leading end portion of the unopened neck portion, into a curled portion and shaping a threaded portion below the curled portion. Therefore, a protective covering film can be formed in a homogeneous state on the metallic surface of the can. On the other hand, a decorative print can be satisfactorily applied to the outer surface of the body portion of the can. For handling the can at the printing step, moreover, there can be converted a transfer apparatus by the vacuum or compressed air injection mechanism which has been employed in the prior art.

In a paper web feed unit of a rotary press, a paper web taken out of a paper roll is longitudinally cut into first and second cut paper webs, which are fed out toward the downstream side by a driven roller of a feed-out mechanism, and only the first cut paper web is passed through an angle bar section for transferring the traveling path of the first cut paper web. The paper web feed unit is equipped with a paper web traveling tension controller which comprises a dancer roller mechanism for independently applying a predetermined pushing pressure to each of the first cut paper web passing through the angle bar section and the second cut paper web not passing through the angle bar section, a detector for detecting the positions of dancer rollers moved in a synchronized manner, and a controller for receiving a detection signal output from the detector and for outputting a control signal to a motor for the driven roller in order to control the rotational frequency of the driven roller to thereby maintain each of the dancer rollers at a constant position.
