Patent number: 8956028Abstract: A light projection unit capable of improving light use efficiency is provided. This light projection unit includes: a fluorescent member that includes an illuminated surface to which laser light is directed, converts at least part of the laser light into fluorescent light and outputs the fluorescent light from chiefly the illuminated surface; and a reflection member that includes a first reflection surface which reflects the fluorescent light output from the fluorescent member. The illuminated surface of the fluorescent member is inclined with respect to a predetermined direction in such a way that the illuminated surface faces in a direction opposite to a light projection direction.Type: GrantFiled: April 19, 2012Date of Patent: February 17, 2015Assignee: Sharp Kabushiki KaishaInventors: Koji Takahashi, Yoshiyuki Takahira, James Suckling, David Montgomery

Patent number: 8814405Abstract: A headlamp of one embodiment of this invention includes a laser element for emitting a laser beam, a light emitting section for generating fluorescence upon receiving the laser beam, and a reflecting mirror for projecting the fluorescence. Distribution of the fluorescence emitted by the light emitting section corresponds to Lambertian distribution, and an incident angle of the laser beam with respect to an excitation light irradiated surface, which is a surface of the light emitting section irradiated with the laser beam, is set so that use efficiency of the fluorescence emitted by the light emitting section is increased.Type: GrantFiled: October 28, 2011Date of Patent: August 26, 2014Assignee: Sharp Kabushiki KaishaInventors: Koji Takahashi, Yoshiyuki Takahira, David Montgomery, James Suckling

Patent number: 8733993Abstract: A headlamp of an embodiment of this invention includes a laser element, a light emitting section, and a parabolic mirror. A part of the parabolic mirror is provided so as to face an upper surface of the light emitting section, which upper surface has a larger area than that of a side surface of the light emitting section. The light emitting section emits fluorescence in such a manner that distribution of the fluorescence corresponds to the Lambertian distribution.Type: GrantFiled: October 28, 2011Date of Patent: May 27, 2014Assignee: Sharp Kabushiki KaishaInventors: Koji Takahashi, Yoshiyuki Takahira, David Montgomery, James Suckling

Patent number: 6849628Abstract: The present invention relates to the preparation of substantially pure diastereoisomers of derivatives of tetrahydrofolate and the use of such diastereoisomers. More particularly the present invention provides a process for the preparation of a desired substantially pure (6R or 6S) diastereoisomer of a derivative of tetrahydrofolic acid or salt or ester. The process comprises the steps of: attaching a chiral auxiliary group at either N-5 or N-10 of a mixture of 6R and 6S diastereoisomers of tetrahydrofolic acid, separating the new diastereoisomers, recovering the desired new diastereoisomer (6R or 6S) corresponding to the desired (6R or 6S) diastereoisomer, and converting the substantially pure new diastereoisomer recovered into the corresponding diastereoisomer.Type: GrantFiled: August 27, 2002Date of Patent: February 1, 2005Assignee: The University of StrathclydeInventors: Hamish Christopher Swan Wood, Colin James Suckling, Lilias Gilmour Rees
