Patent number: 11921365Abstract: An isolator includes a first core, a second core, a nonreciprocal member, and a magnetic body. The first core and the second core extend in a first direction and are positioned side by side with a cladding therebetween in a second direction that intersects the first direction. The nonreciprocal member is in contact with at least a part of the second core while being positioned side by side with the second core in the second direction. In a magnetic field generated by the magnetic body in a portion where the nonreciprocal member is positioned, a component in a third direction perpendicular to the first direction and the second direction is greater than any component other than the component in the third direction.Type: GrantFiled: July 20, 2020Date of Patent: March 5, 2024Assignee: KYOCERA CorporationInventors: Hiromichi Yoshikawa, Naoki Matsui, Tomoya Sugita

Patent number: 6874395Abstract: A punching device of the present invention is proposed which can perform positional alignment with high accuracy without generating positional deviation or vibration by shifting a workpiece, and which does not deteriorate the accuracy of determining the position of an image by shifting a photographic device. In this punching device, a CCD camera, which can photograph the position of the die hole upon the lower die and the position of the pattern upon the workpiece which shows the position thereon where punching is to be performed, is fixedly provided at a position removed from the raising and lowering track of the punch plate. Furthermore, a mirror may be provided between the CCD camera and the die hole upon the lower die.Type: GrantFiled: February 22, 2002Date of Patent: April 5, 2005Inventors: Toru Ishii, Hiromichi Matsui, Yasuaki Mizuno, Makoto Teraoka

Patent number: 5351081Abstract: A solid-state imaging device in which a light-barrier layer is formed on transfer electrodes on top of a vertical pixel isolating region by an insulating film. The light-barrier layer is adapted to overlie the lateral sides of the transfer electrodes and the peripheral region of a photosensor region neighboring on the vertical pixel isolating region. By provision of the light-barrier layer, the light incident on the vertical pixel isolating region is stopped to reduce smear charges which might otherwise be intruded into the vertical charge transfer section.Type: GrantFiled: December 23, 1993Date of Patent: September 27, 1994Assignee: Sony CorporationInventors: Hiromichi Matsui, Kazuomi Ezoe, Toshiro Kurusu

Patent number: 5014132Abstract: A CCD imager includes a large number of light receiving sections each having in turn a semiconductor surface region of a second conductivity type, a first semiconductor region of a first conductivity type, a semiconductor region of the second conductivity type and a second semiconductor region of the first conductivity type, vertically. The second semiconductor region is formed by a dual structure of the low concentration semiconductor region and the high concentration semiconductor region. The dual structure provides for shuttering at a lower voltage since the potential barrier along the depth of the light receiving section is no longer affected by the amount of the stored charges, while spreading of the depletion layer at the junction is suppressed by the high concentration semiconductor region.Type: GrantFiled: July 21, 1989Date of Patent: May 7, 1991Assignee: Sony CorporationInventors: Tetsuro Kumesawa, Yasuo Kanou, Osamu Nishima, Masaaki Isobe, Hiromichi Matsui
