Patent number: 7708471Abstract: The present invention is provided to obtain an inexpensive bidirectional optical module wherein a diffraction efficiency can be maximized at different diffraction order for light beam with different wavelength, and light usage efficiency is enhanced. The bidirectional optical module includes a light-emitting element for transmitting an optical signal toward an end of an optical fiber; a light-receiving element for receiving an optical signal from the end of the optical fiber; and a grating in which stair shapes are repeated with a predefined pitch. In the bidirectional optical module, a phase function is defined as phase-difference contour lines which is formed by making two light fluxes from predetermined positions interfere with each other on a surface arranged at a position of the grating. A planar pitch of the grating is formed such that values of the phase function form phase contour lines each representing an integer multiple of 360 degrees.Type: GrantFiled: June 5, 2006Date of Patent: May 4, 2010Assignee: Konica Minolta Holdings, Inc.Inventors: Yukihiro Ozeki, Kazumi Furuta

Patent number: 7697030Abstract: A monitor camera is provided with a control device which carries out a predetermined process in response to an input of a trigger signal. The control device has an arrangement in that continuous images are successively inputted from a camera unit thereto and in that a detection of a moving object is carried out by detecting a change in images in a moving-object detector. When no change in images is detected by the moving-object detector within a predetermined time after the input of a trigger signal from a detection sensor to a trigger signal input unit, the control device determines the trigger signal inputted to the trigger signal input unit as valid. Then, only when the valid trigger signal has been detected, an abnormality process is carried out. Consequently, it is possible to prevent the abnormality process from being performed upon erroneous detection of a normal state as an abnormal state.Type: GrantFiled: December 10, 2003Date of Patent: April 13, 2010Assignee: Konica Minolta Holdings, Inc.Inventors: Tomoyuki Terada, Masaru Sawada, Naotaka Kishida, Ayumi Itoh
