The device has a cathode panel between a front panel and a back panel in such a manner that a space is existent between the cathode panel and the back panel, wherein through holes for diffusion of getters are formed in the cathode panel to maintain the image quality at the center of a display screen, or the cathode panel is supported by getters to maintain a required pressure, hence attaining a higher image quality even on a large-sized display screen. A gate electrode may be composed of a getter material.

A frontal hairpiece for providing a naturally-appearing augmented frontal hairline when applied to the wearer. A frontal foundation has a forward edge, a rearward edge, a first end and a second end. The frontal foundation is thin, flexible and made from a net-like construction which substantially blends with the skin color of the wearer. The forward edge traces a tortuous pathway from approximately the first end to approximately the second end. Embodiments may include an elastic band portion connected to the frontal foundation, with first and second rear strap portions disposed therebetween. Hair is attached to the frontal foundation in a first density pattern which mimics a natural transition of a wearer's forehead into a frontal hairline. The first density pattern of some embodiments may be characterized by a greater density of hair strands applied proximate the rearward edge of the frontal foundation compared to the density of hair strands applied proximate the forward edge.

A method of producing a bead inductor includes the steps of forming an outer portion outside of a conductor coil, and forming a molded body with the conductor coil embedded therein. The outer portion is formed outside of the conductor coil by disposing the conductor coil in a cavity defined by first and second mold portions, with first and second gates formed in the first mold portion, inserting first and second spacer pin portions, which define a spacer pin which passes through the conductor coil and extends to and closes the second gate, and supplying material containing magnetic powder into the mold cavity from the first gate. The molded body is formed by closing the first gate after the formation of the outer portion, and supplying from the second gate material containing magnetic powder into a space formed by removing the spacer pin portions.

A taking part has a taking unit that comes in contact with the piled sheets to generate a taking force and to take the sheets one by one with the taking force. A movable lever is arranged in a side of the taking unit with respect to the piled sheets, and a driving unit gives a driving force in a linear or rotational direction to the movable lever. A force controller controls the driving force given to the movable lever by the driving unit. A detecting unit detects a position of the movable lever, and a sheet supplying unit supplies the piled sheets to the taking unit. A sheet supplying unit controller controls the sheets supplying unit on the basis of the position of the movable lever detected by the detecting unit. The sheets are pressed by the lever at a preparatory step, and then the sheets are lifted and pressed to the taking unit while canceling the driving force by the lever. The sheet and the taking unit are assured to become in good contact with each other to make the taking operation stable.

An actuator includes a shear-type piezoelectric element of predetermined thickness and an opposed electrode formed on two electrodes in spaced relationship on a base member. The opposed electrode is displaced in accordance with the direction of polarization of the shear-type piezoelectric element upon applying a voltage between the two electrodes. The opposed electrode thus constitutes an operating section of the actuator. The actuator can be incorporated as a part of the head actuator to constitute a head-positioning mechanism capable of displacing the head by a minuscule distance independently of the operation of the head actuator.

A spilled oil collection catamaran includes a submerged waterfoil extending between a pair of floats and submerged at its bow, a rotating impeller extending between the floats and above the waterfoil with its bottom partly dipped in the water, a spraying pipe extending between the floats and in front of the impeller for spraying a gelling agent for having the spilled oil drifting in the water surface gelled, and a vertically movable cage in the rear of the impeller for housing therein a porous collection bag which has an open side directed toward the bow to collect gelled oil in the bag. The catamaran also includes a spray gun at the bow for spraying the gelling agent over the spilled oil drifting in the water surface in front of the catamaran.

The invention includes an irradiation nozzle which radiates a line scanning beam, an irradiation position sensor which detects an irradiation position of the line scanning beam, an arithmetic processing circuit unit which measures the stationary time of the line scanning beam at the irradiation position detected by the irradiation position sensor, and an irradiation control unit which performs scanning control of the line scanning beam by utilizing the irradiation position measured by the irradiation position sensor and the stationary time detected by the arithmetic processing circuit unit. According to this line scanning apparatus, scanning control of the line scanning beam is performed by utilizing the irradiation position of the beam and the stationary time corresponding to the irradiation position, so that irradiation of the beam to an erroneous position or excessive irradiation of the line scanning beam can be more reliably prevented, and thereby the reliability of the line scanning apparatus can be improved.
