Publication number: 20200290318Abstract: The use of camera-based safety systems is growing at a rapid rate in modern automobiles. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. However, the optical quality of the windshield is less than optimal. One of the problems is caused by the typical black enamel frit that is printed on the glass, prior to heating and bending, to hide or obscure the camera hardware. The abrupt thermal gradients during bending, caused by the heat absorbing black frit, result a high level of distortion in the camera field of view.Type: ApplicationFiled: September 29, 2018Publication date: September 17, 2020Inventors: Mario Arturo MANNHEIM ASTETE, Charles S. VOELTZEL, Laura GRANADOS CARO, Andres Fernando SARMIENTO SANTOS, Elena K. MENDOZA CARRANZA

Publication number: 20200290319Abstract: Black enamel frit obscurations are commonly printed on laminated and tempered automotive safety glazing where they serve to hide the adhesive used to bind the glazing to the automotive body and to protect the adhesive from ultraviolet radiation. However, frit has a number of drawbacks. Frit weakens the surface of the glass. It can create distortion in the glass due to thermal gradients. Printed frit obscurations are incompatible and cannot be used with many types of coatings. Standard frit blocks ion exchange and cannot be used with the chemical tempering process. In addition, while many types of frits are available for printing on soda-lime glass, there are very few, if any, for non-soda lime glass. As the market moves towards thinner and lighter glazing, non-soda lime glass types are finding increasing application in automotive glazing. These limitations are overcome by replacing the printed black obscuration with an obscuration formed from a thin sheet of plastic, which is integrated into the laminate.Type: ApplicationFiled: September 29, 2018Publication date: September 17, 2020Inventors: Mario Arturo MANNHEIM ASTETE, Charles S.

Publication number: 20200290362Abstract: A liquid ejection apparatus includes: a recording head that ejects liquid; a sub-tank that is connected to the recording head and temporarily stores the liquid to be supplied to the recording head; a liquid tank that communicates with the sub-tank and is able to be filled with the liquid; a first atmosphere opening unit that is provided in the liquid tank; and a second atmosphere opening unit that is provided in the sub-tank. The second atmosphere opening unit is closable when the liquid tank is filled with the liquid, and the first atmosphere opening unit and the second atmosphere opening unit are able to open the liquid tank and the sub-tank to the atmosphere, respectively, when the sub-tank is filled with the liquid filled in the liquid tank by a hydraulic head pressure.Type: ApplicationFiled: February 28, 2020Publication date: September 17, 2020Inventors: Hiroki Tajima, Keiichiro Tsukuda, Kenji Yabe, Yuji Tamaru, Naoko Shimizu, Kyosuke Toda, Sayaka Seki, Yosuke Takagi, Shimpei Yoshikawa, Ryo Sato

Publication number: 20200290363Abstract: A liquid ejection apparatus includes a plurality of liquid ejection units ejecting different types of liquids. Each liquid ejection unit includes an ejection orifice which ejects a liquid, first and second liquid tanks which store the liquid, and a liquid flow path which connects the first liquid tank and the second liquid tank to each other across the ejection orifice. The liquid ejection apparatus further includes a cap member which covers of the ejection orifices of the plurality of liquid ejection units and forms a space sealed between the ejection orifices of the plurality of liquid ejection units and the cap member, and a pressure control mechanism which simultaneously pressurizes the first and second liquid tanks.Type: ApplicationFiled: March 6, 2020Publication date: September 17, 2020Inventors: Yohei Nakamura, Kazuhiro Yamada

Publication number: 20200290364Abstract: An ink supply system for a print bar of an inkjet printing device comprises two supply lines that travel along the longitudinal axis of the print bar and direct ink with opposite flow direction. The print heads of the print bar are respectively connected to both supply lines via a connecting line in order to supply ink to said print heads. A uniform mean hydraulic pressure is produced in all print heads via the opposite flow directions in the two supply lines.Type: ApplicationFiled: March 11, 2020Publication date: September 17, 2020Applicant: Canon Production Printing Holding B.V.Inventors: Wolfgang Hettler, Florian Hitzlsperger, Christoph Rummelsberger

Publication number: 20200290366Abstract: White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).Type: ApplicationFiled: September 23, 2019Publication date: September 17, 2020Inventors: Peter HEATH, Joseph A.

Publication number: 20200290367Abstract: A control unit controls a print head to print a print image by ejecting ink through a nozzle to form dots on a print medium and a movement unit to impart relative movement between the print head and the print medium to print a print image on the print medium. The control unit obtains a dot adjustment value in the predetermined print operation based on the measurement result of a measurement unit measuring a first pattern composed of a print image printed by the predetermined print operation including the relative movement, and a second adjustment value for adjusting dot printing positions in the predetermined print operation in a unit of length shorter than in the adjustment using the first adjustment value based on a second pattern printed by the predetermined print operation in a density according to density information on the first pattern, measured by the measurement unit.Type: ApplicationFiled: March 4, 2020Publication date: September 17, 2020Inventor: Hiroshi Kawafuji
