Abstract: An electric stove includes an electric heating element arranged at a distance from a position right below a target to be heated. A first mirror surface portion is arranged to surround the electric heating element and configured to reflect heat rays radiated from the electric heating elements. A second mirror surface portion is arranged below the electric heating elements and configured to collect the heat rays reflected by the first mirror surface portion to a side below the target by reflecting the heat rays substantially immediately upwardly. The first mirror surface portion includes a plurality of partial elliptical mirror surface portions having one focus near the electric heating elements and the other focus below the electric heating elements, and the second mirror surface portion includes a partial elliptical mirror surface portion a having one focus near the electric heating elements and the other focus below the electric heating elements.

Abstract: It is aimed to provide an electric stove which is further improved to be able to further reduce a loss in terms of thermal efficiency by further increasing the reflection efficiency of heat rays on a mirror surface portion. An electric stove 10 includes electric heating elements 36 arranged at a distance from a position right below targets to be heated W, a first mirror surface portion 12 arranged to surround the electric heating elements 36 and configured to reflect heat rays radiated from the electric heating elements 36, and a second mirror surface portion 14 arranged below the electric heating elements 36 and configured to collect the heat rays reflected by the first minor surface portion 12 to a side below the targets to be heated W by reflecting the heat rays substantially immediately upwardly.

Abstract: An object is to provide an electric stove which can increase the flexibility of design and further improve thermal efficiency. An electric stove 10 includes electric heating elements 32a and 32b disposed out of positions immediately below objects to be heated 62, partially elliptical mirror sections 16a and 16b reflecting heat rays radiated from the electric heating elements 32a and 32b, and first reflective mirror sections 22a and 22b disposed below the electric heating elements 32a and 32b to gather the heat rays reflected by the partially elliptical mirror sections 16a and 16b towards the lower sides of the objects to be heated 62. The partially elliptical mirror sections 16a and 16b have one foci F1a and F1b in the vicinity of the electric heating elements 32a and 32b, respectively.

Abstract: An ink jet printer head which prints by jetting out ink from a nozzle by means of a heating element. The printer head has two ink chambers above the heating element, with a partition plate separating the two ink chambers. There are at least two holes in the partition plate and allow ink to pass therethrough. At least one of the two holes and the nozzle are provided substantially coaxially with the center of the heating element.

Abstract: Two-stage skew adjustment is achieved by first using only the drive force of the platen roller with the pinch roller and the capstan roller drive disrupted by a gap opening mechanism to effect a large skew adjustment. Then, the gap is closed and the platen roller, which has a Teflon-resin coating thereon and a larger diameter than the capstan roller or pinch roller, effects a small skew adjustment. Thereafter, printing is effected by feeding the paper in a reverse direction to register with an inked ribbon feed of a primary ribbon using the platen roller drive and the pinch roller drive with the skew cycle repeated for each ribbon color segment to achieve improved multicolor printing registration.

Abstract: The present invention relates to a printer, and more particularly to a heat transfer printer. The printer comprises: a pair of upper and lower chutes for guiding printed paper; an idle roller provided on the upper chute; a paper discharging motor bracket provided on the lower chute; a paper discharging lever rotatably provided on the paper discharging motor bracket; and a paper discharging pulley disposed at a tip of the paper discharging lever, wherein, at the time of discharging the paper, the paper discharging lever is rotated by a driving force of a motor provided on the bracket to cause the paper discharging pulley to project from the lower chute so as to come into contact with the idle roller, while, at the time of printing, the motor is stopped.

Abstract: The present invention relates to a printer which is capable of eliminating the slack of paper, wherein, at the time of printing, the paper is fed by a pinch roller, while, at the time of paper feeding, the paper is caused to slide relatively at least on a platen roller.

Abstract: The present invention relates to a ribbon feed mechanism for use in a heat transfer printer. The ribbon feed mechanism includes first, second, and third ribbon feed components fitted on a shaft, a friction plate mounted between the first and second ribbon feed components, a spring mounted between the second and third ribbon feed components, a cylinder which is in contact with the third ribbon feed component at one end thereof, and a ribbon feed presser for pressing the other end of the cylinder toward the third ribbon feed component. The rotational torque is always kept constant, and therefore no unmatching of colors occurs when the mechanism is applied to a printer.

Abstract: The present invention relates to a recording paper winding apparatus for winding a recording paper on a rotary drum, by providing a bar for pinching a front end of a recording paper between the bar and the outer surface of a rotary drum, whereon a recording paper is to be sucked by making inside a negative pressure. Thus, the recording paper can be wound on the drum by a simple operation and held tightly thereon.

Abstract: A separation mechanism part is provided wherein a negative pressure to suck a recording paper apart from a stack is obtainable by contacting an uppermost sheet of the recording paper using a suction head, air flow into the suction head being cut off by contact of the suction head with the first sheet of the recording paper. The recording paper is sucked and separated one sheet by one sheet by bringing up the suction head, as such, by the negative pressure. This paper feeding apparatus can feed recording paper surely separated sheet by sheet, and even though the amount of piling of the recording paper in the piled state changes, the separating force applied to act on the uppermost sheet of recording paper when suction is applied is kept small and uniform.

Abstract: An apparatus for draw forming glass filaments includes a melt furnace 1 having a bottom plate 12 with a plurality of flow holes therein, each terminating in a conical nozzle tip 2. Cooling fins 10 extend outwardly from a water pipe 11 and are disposed between the rows of tips, and additional cooling is provided at least during the initial start-up period by air blown across the nozzle tips from a manifold 13 disposed opposite the water pipe. With such an arrangement the flow hole diameters may be increased, which results in an exponential increase in the molten glass flow rate and filament production rate, while still achieving smooth initial and stable continuous filament forming conditions.
