To clean dusts from a printing cylinder of a blanket, an impression drum or the like can be simply discharged with no adhesion in a casing of a cleaning machine. A cleaning device incorporates a rotary brush in the casing which is disposed opposite to the printing cylinder. An opening is formed in a cylinder confronting portion of the casing, and the cylinder surface can be cleaned by the brush, with some portion of the brush fronting. Provided in the casing is a scraper for eliminating the adhe...

A printer device has a print body on one end of which a print head is mounted, the print body being longitudinally movable along an inking stroke and a printing stroke, with the printing stroke being angularly offset by approximately 90.degree. from the inking stroke, and with the print body being pivotally movable through an intermediate pivot stroke between the inking stroke and the printing stroke. A piston and cylinder assembly is connected to the print body for operatively causing advance m...

It is an object of this invention to make it possible to accurately simulate a manner in which carriers are transferred in a semiconductor device. A Fermi level setting means sets a Fermi level in a sink region of carriers, such as a vertical CCD portion of a CCD, and Boltzmann distribution equation solving means solve a Boltzmann distribution equation to obtain a carrier density in this Fermi level set region. In a CCD, the manner in which carriers are transferred from a photodiode portion to a...

A semiconductor device is carried in compressive contact relationship between two vapor cooling containers put in fluid communication with condensers disposed above them through connection tubes respectively. A condensible liquid coolant fully fills each container, and the associated connection tube and partly fills the mating condenser. One auxiliary tube is disposed within each connection tube and has a bent upper end opening in the associated condenser below the liquid surface of the coolant ...

A filter device is mounted in a backlight device for illuminating a transmission type liquid crystal display panel from the rear surface side. The filter device includes a sheet having a polygonal filter portion for imparting predetermined optical characteristics to rays of light emerging from the light exit surface of a light guide and a holding portion extending from one side of the filter portion, a frame member having a polygonal opening portion in correspondence with the filter portion to a...

The total heating energy to be given to the folded parts of packages (i.e. box-like items) is changed within a short period of time in response to a variation of transferring speed of the box-like items. As the heater moving mechanisms are operated, each of the heater blocks is moved towards or away from the inside parts of each of the package conveying annular belts in synchronization with the transferring speed of the box-like items. The number of heated blocks abutting against the inside part...

A control device includes a control mechanism for eliminating a dark current effect generated in a CCD. The control mechanism carries out a charge pumping operation in the CCD during a time after an object is photographed up until the time when an aperture is closed. The control mechanism obtains a dark current component generated when the aperture is closed after a photographing operation, based on a dark current component outputted by the CCD during a predetermined period, and then subtracts t...

A condensing device for a sputtering device capable of condensing metal atoms to be ejected from a metal target onto a semiconductor substrate in a scattered manner and thereby easily depositing the metal atoms on side walls of contact holes formed at the semiconductor substrate is disclosed. The condensing device includes a plurality of condensing tubes arranged in the form of a bundle and adapted to condense the metal atoms ejected from the metal target, each of the condensing tubes being cons...

A recording device, comprising a probe electrode, a recording medium having electric memory effect and a writing voltage applying unit for applying voltage onto the recording medium from the probe electrode, and a reproducing device comprising a probe electrode, a recording medium exhibiting electric memory effect or a recording medium recorded by energy irradiation, a voltage applying unit for applying voltage not exceeding the threshold value voltage giving rise to electric memory effect onto ...
