Patents by Inventor Takayoshi Shimomura

Takayoshi Shimomura has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Light guide, light source apparatus, and electronic apparatus
    Patent number: 7717598
    Abstract: A light guide is disclosed. The light guide includes an incident surface, an exit surface, and a light guide section. Light emitted from a plurality of light emitting devices disposed in line enters from the incident surface. The exit surface is formed in a shape causing light to be concentrated. The light which has entered from the incident surface exits from the exit surface. The light guide section is bent. The volume of the light guide gradually increases in a direction from the incident surface to the exit surface.
    Type: Grant
    Filed: November 9, 2007
    Date of Patent: May 18, 2010
    Assignee: Sony Corporation
    Inventors: Akinori Kakizaki, Takayoshi Shimomura, Yoshinori Yamazaki

  • Enameled cold rolled sheet
    Patent number: 4084991
    Abstract: An enameling steel sheet characterized by a manganese content of 0.50 wt.% or under and the elimination of annealing after the final cold rolling. A satisfactory enamel adhesive property can be obtained by enameling and baking said enameling steel sheet in as-cold-rolled state after only degreasing and drying.

  • Method of making a soft steel sheet by continuous annealing
    Patent number: 4026729
    Abstract: In a process of making a cold-reduced steel strip for press-forming by a continuous annealing process comprising a rapid cooling step after recrystallization heating and an over-aging treatment step, when no spray of cooling water at the runout table before coiling in the hot-rolling stage is carried out on the top side and the bottom side of a travelling hot-rolled steel strip by about 20 to 200m respectively, a cold reduced soft steel sheet for press-forming is easily obtained by the above continuous annealing process.

  • Enameling cold rolled steel sheet with a high enamel adhesive property
    Patent number: 4019929
    Abstract: An enameling cold rolled steel sheet with a high enamel adhesive property which requires no pickling step before enameling, characterized by an Mn content kept within 0.05 to 0.20%, and the relation between the surface roughness and the Mn content of said steel sheet satisfying at least one of the following two equations:(a) Number of peaks of 1.3.mu. and over/inch .gtoreq. 1,200.sup.. (Mn% - 0.1)(b) R.sub.z (.mu.) .gtoreq. 60.sup.. (Mn% - 0.

  • Process of making cold reduced Al-stabilized steel having high drawability
    Patent number: 3959029
    Abstract: In a two stage cold reducing process, Al-stabilized steel is subjected to a decarburizing treatment as intermediate annealing between the first and second cold reducing, to impart unexpectedly high drawability to Al-stabilized steel, the drawability being more than 2.00 r (Lankford value). Such Lankford value shows that the steel is capable of sustaining any severe press forming.
