Patent number: 11833540Abstract: An applicator head for a curtain applicator for coating a continuous material web with liquid or pasty application medium. The applicator head has an outlet edge extending substantially over the width of the applicator head. The application medium passes out of the applicator head in a free-falling curtain. A rinsing device allows the outlet edge to be supplied with a flowing gaseous rinsing medium. There is also described a method for coating a continuous material web by way of such a curtain applicator. The application medium passes out of the applicator head in the form of a free-falling curtain and subsequently comes into contact with the material web. The region of at least one of the outlet edges can be supplied with a flowing gaseous rinsing medium.Type: GrantFiled: May 11, 2017Date of Patent: December 5, 2023Assignee: Voith Patent GmbHInventors: Tadashi Sasa, Toshihiro Katano, Akio Hirano, Hiroyuki Kohno, Christoph Henninger, Uwe Froehlich

Patent number: 8873124Abstract: A plastic optical element for focusing light to a target includes a first lens and a second lens. The first lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion. At least one light beam passes from the incident surface to the projection surface. The second lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion disposed opposite the non-optical surface of the first lens. At least one light beam passes from the incident surface to the projection surface. The non-transfer portions of the first lens and the second lens are portions on which no surface is transferred from a surface of a mold used to form the plastic optical element.Type: GrantFiled: June 3, 2011Date of Patent: October 28, 2014Assignee: Ricoh Company, Ltd.Inventors: Go Takahashi, Eiichi Hayashi, Akio Hirano, Takamichi Ohta, Kan Aoki

Patent number: 8824035Abstract: A molded plastic part prepared by injecting a resin in a cavity of a die so that a pressure is generated in the resin in the cavity and at least one transfer wall surface of the cavity is transferred to the resin. The plastic part has at least one transferred surface; at least one imperfectly transferred concave portion on a first surface thereof other than the transferred surface; and at least one imperfectly transferred convex portion on the first surface or a second surface thereof other than the transferred surface. The ratio (a)/(b) of the thickness (a) of the plastic part in a direction perpendicular to the transferred surface to the thickness (b) of the plastic part in a direction parallel to the transferred surface is less than 1.Type: GrantFiled: December 6, 2010Date of Patent: September 2, 2014Assignee: Ricoh Company, LimitedInventors: Takamichi Ohhashi, Yasuo Yamanaka, Akio Hirano, Eiichi Hayashi, Go Takahashi, Kan Aoki

Publication number: 20120063811Abstract: A resin casting mold includes a mold member forming a cavity that includes first and second surfaces facing each other in a first direction. The mold member further includes an insert member which forms a part of a third surface and which is slidable in a second direction perpendicular to the first direction. At least one cross-sectional shape of the cavity satisfies h<A<H, where “A” is the length of the insert member in the first direction, “h” is a spacing in the first direction between a portion of the first surface closest to the insert member and a portion of the second surface closet to the insert member, and “H” is the length in the first direction on the third surface. The insert member is disposed to include a region having the spacing “h”.Type: ApplicationFiled: September 8, 2011Publication date: March 15, 2012Inventors: Takamichi Ohhashi, Eiichi Hayashi, Akio Hirano, Go Takahashi, Chieko Hatashita

Patent number: 7556693Abstract: This invention relates to a curtain applicator on which a two-layer curtain is formed by dispensing two types of coating medium, for example color, from a medium feeder positioned to the upper side of a moving web in order to apply two layers of coating medium onto the web surface. The medium feeder has a middle lip, which is arranged in the flow channels for the two types of medium and has a pointed part projecting toward the web side from the pointed parts of the two side lips which are arranged on the outer side of the flow channels for the two types of medium on the outer side in the width direction of the web. The curtain applicator also includes a convexly formed medium separation device, which adjoins the pointed part of the middle lip and individually separates the two types of surplus medium, for example, color, which are dispensed from the medium feeder.Type: GrantFiled: August 23, 2007Date of Patent: July 7, 2009Assignee: Voith Patent GmbHInventors: Hirofumi Morita, Akio Hirano, Hiroyuki Kohno
