摘要:
A thermal transfer type color printer of this invention has four ink ribbons sequentially arranged from a first order to a fourth order along a conveying direction of a printing medium, and four printing heads respectively arranged in accordance with the four ink ribbons. Each of the printing heads melts and transfers ink included in each of the ink ribbons to the printing medium by heating the ink ribbons while each of the ink ribbons comes in contact with the printing medium. While the printing medium is conveyed, the ink of each of the ink ribbons is transferred to the printing medium so that a color image is formed. In this color printer, a melting viscosity of the ink of an ink ribbon used at a later stage is set to be lower than that used at a previous stage.

A deviation test pattern includes a reference scale printed by one reference printing unit among a plurality of printing units arranged to print overlaid images of yellow, magenta, cyan and black. The reference scale has a plurality of scale bars arranged in a main-scanning direction at a pitch of 30 dots. Particularly, the deviation test pattern further includes a difference scale printed adjacent to and in parallel to the reference scale by a printing unit other than the reference printing unit. The difference scale has a plurality of scale bars arranged in the main-scanning direction at a pitch of 29 dots (or 31 dots).

A wheel, made of aluminium, for an automobile, including an aluminum body part, and a cover as a design part which is removably fitted to the aluminum body part. The aluminum body part, including a rim part and a disc part, imparts a desired strength to the wheel. The cover has a substantially disc-shaped cover body that covers a front face of the aluminum body part, and fixing means, arranged circumferentially with a spacing therebetween, which is installed on a rear surface of the cover body.

An attaching structure of a wheel cap for attaching a flexible annular molding to a wheel cap body of a car, by which the former is easily and surely attached to the latter. An engaging leg of the flexible annular molding includes a proximal portion, a first engaging part, a second engaging part, and a distal end part. The first and second engaging part includes a first and a second projecting part, respectively. These first and second engaging parts project in a direction generally perpendicular to a direction in which the engaging leg extends, and project in different directions. The annular molding includes a first concave part between a molding body and the first projecting part; and a second concave part between the molding body and the second projecting part. Meanwhile, the wheel cap body includes a through-hole whose inner length corresponding to both the axial direction and the first concave part is approximately equal to a length in the axial direction of the first concave part, and whose inner length corresponding to both the axial direction and the second concave part is approximately equal to a length in the axial direction of the second concave part.

Resistance of a thermal head is stored as a digital signal in a head resistance memory. Output according to data in the head resistance memory is calculated by a head voltage calculation circuit for storing a correlation between resistance of the thermal head at a fixed normal temperature and supply voltage. The output from the head voltage calculation circuit is converted by a D/A converter to a reference voltage, which is then fed to a constant-voltage power source for applying the supply voltage to the thermal head, so that an optimum supply voltage to the thermal head may be automatically set, and temperature of the thermal head generating heat may be maintained constant.

This invention relates to a method of producing interior material of corrugated cardboard used for a ceiling of a car, for example.Corrugated cardboard base material is plasticized by being heated and moistened while in a flat plane. Thereafter, the corrugated cardboard base material thus plasticized is pressed in a forming die having a low temperature such as a room temperature to be shaped in a predetermined manner. Afterward a covering sheet is disposed thereon having a thermally melting sheet provided thereon so as to be faced toward the corrugated cardboard base material thus shaped, they are pressed in the forming die to melt the thermally melting sheet by the preheated shaped corrugated cardboard base material to bond the covering sheet to the corrugated cardboard base material so as to produce interior material.

Efficiently suppressing chatter of a mirror face of a mirror. In a vehicle door mirror device, a case is disposed at a back face side of a mirror, a substrate unit is accommodated in the case, gap between the mirror and the case is sealed by sealing agent, thereby sealing the substrate unit. The holder, the case and the sealing agent are integrated together. A press contact tab is integrally provided to a housing box of the holder such that the press contact tab makes press contact with an anti-vibration pillar. The supporting rigidity to the mirror at the position of the substrate unit can accordingly be efficiently raised, vibration of the mirror due to the substrate unit can be efficiently suppressed, and chatter of a mirror face of the mirror can be efficiently suppressed.
