Publication number: 20140043686Abstract: Provided is an immersion diffraction element that prevents decrease of diffraction efficiency thereof so as to satisfy optical performance. A reflection type diffraction element is made of a material transmitting a light, beam having a predetermined wavelength. An echelle diffraction grating covered with a reflecting film that prevents transmission of the light beam is formed on one surface of the material. A diffraction grating is formed off in a repeated manner, a blazed surface facing incident light and a non-blazed surface connecting the blazed surface to a neighboring blazed surface. An angle formed between the blazed surface and the non-blazed surface is an acute angle. A defect generated at a grating vertex of the blazed surface fails in a shadow of the neighboring blazed surface so as to prevent the incident light from becoming scattered light due to the defect portion.Type: ApplicationFiled: July 30, 2013Publication date: February 13, 2014Applicant: CANON KABUSHIKI KAISHAInventors: Shigeru Sugiyama, Masato Tanaka

Patent number: 6763120Abstract: A low cost dynamic speaker (10) prevents damage of the diaphragm (16) when the speaker (10) is mounted on a printed circuit board (2). An insulating ring (22) is attached to the front surface of the diaphragm (16) at the periphery. The insulating ring (22) has a pair of terminal pins (24) supported thereon for continuity of the lead wire (18a) with the conductor (4) of the printed circuit board (2). The conducting portion (24b) of each of the terminal pins (24) is protruded forward beyond the annular flat surface (22a) of the insulating ring (22).Type: GrantFiled: March 20, 2002Date of Patent: July 13, 2004Assignee: Star Micronics Co., Ltd.Inventors: Shigeru Sugiyama, Hajime Kitamura, Yoshio Imahori

Patent number: 6691832Abstract: The diaphragm is supported by the frame at the outer edge thereof. The pair of terminal members is mounted on the frame, and a pair of lead wire drawn from the voice coil is fixed to the land portion of the terminal member for electrical continuity. Since the land portion is disposed on the upper side of the frame, fixation of the lead wire can be performed without turning the frame upside down. This simplifies the manufacturing process of the speaker and also prevents a breakage of the lead wire that conventionally happens when the frame is turned upside down. Further, this prevents the operator from touching the lead wire since no part of the lead wire is exposed outside the frame after the fixation.Type: GrantFiled: May 9, 2002Date of Patent: February 17, 2004Assignee: Star Micronics Co., Ltd.Inventors: Fuminori Moritake, Shigeru Sugiyama, Naohiro Fujinami, Tomoyuki Sato, Yoshio Imahori
