摘要:
A paper feeder for a printer in which a paper separator roller 15 is rotatably provided in the end portion of a paper holder 12 so that when a paper feed roller 14 is rotated in the paper feed direction, the paper separator roller 15 is arranged to stop at a predetermined position and act similarly to a conventional friction pad, while when the paper feed roller 14 is rotated in the paper return direction, the paper separator roller 15 also rotates in synchronization with the above rotation. By way of vibrating the paper separator roller 15 in the rotational direction or another direction, paper sheets P stacked on the paper holder 12 are vibrated for the purpose of being successively moved in the portion at which the two rollers 14 and 15 are positioned in contact with each other. As a result of this structure, the paper feeder of the printer according to the present invention can be prevented from local abrasion of the paper separator roller 15 causing papers to be fed in an overlap manner, and stop of paper feed can be prevented, and papers can be assuredly fed one at a time to the printing mechanism portion 1.
摘要:
A perfecting printer for performing a double-face printing operation of printing images on obverse and reverse faces of at least one sheet on the basis of a series of print data inputted from an external device and a method for controlling the double-face printing operation of the printer. The perfecting printer includes a page memory for storing as page data at least both of the first and second print data in the series of the print data, and a control unit for printing the first and second print data on both of the obverse and reverse faces of the sheet when it is judged that the page data to be printed on the reverse face of the sheet exists in the memory and promptly printing only the first print data on the obverse face of the sheet when it is judged that the page data to be printed on the reverse face of the sheet does not exist in the memory.

A perfecting printer for performing a double-face printing operation of printing images on obverse and reverse faces of at least one sheet on the basis of a series of print data input from an external device and a method for controlling the double-face printing operation of the printer. The perfecting printer includes a page memory having an empty area for storing a series of print data for the obverse and reverse faces of the sheet input from external device, and a control unit for judging as to whether the empty area is no longer available in the page memory while the series of print data are being stored into the page memory and forcibly printing print data for the obverse face of the sheet on the sheet when it is judged that the empty area is no longer available in the page memory and that only the print data for the obverse face of the sheet are completely stored in the page memory.

An electric power converter can include an electric power converter case mounted on rolling stock, a unit mounting section formed in the electric power converter case and having a cooler insertion opening, and an internal unit mounted on the unit mounting section. The internal unit can include a cooler projecting from the unit mounting section through the cooler insertion opening into an outside air introduction section into which the outside air is introduced and a plurality of securing holders made to butt against the unit mounting section for securing the internal unit. Each of the securing holders can have a butting surface for butting against the unit mounting section to form a step by making the butting surface protrude from the opposed surface of the internal unit facing the unit mounting section.

A method for forming a thin film includes the steps of: supplying a deposition material in the form of a liquid onto a heated surface; heating and vaporizing the deposition material on the heated surface while the deposition material is undergoing movement; and depositing the deposition material onto a deposition surface. The deposition material is supplied onto a position of the heated surface where the vaporized deposition material does not reach the deposition surface.

An LED lamp 100 includes: an LED chip 10; a phosphor resin portion 12 that covers the LED chip 10; and a light-transmissive member 20 that covers the phosphor resin portion 12. The phosphor resin portion 12 includes: a phosphor for converting the emission of the LED chip 10 into light that has a longer wavelength than the emission; and a resin in which the phosphor is dispersed. The surface of the light-transmissive member 20 includes an upper surface portion 22 located over the LED chip 10 and a side surface portion 24 located around and below the upper surface portion 22. At least a part (low-transmittance part 26) of the side surface portion 24 of the light-transmissive member 20 has lower transmittance than the upper surface portion 22.
