20100195019 | SURFACE LIGHT SOURCE APPARATUS - A light guide plate ( | 08-05-2010 |
20150234109 | RELAY - A relay has a case, a relay body disposed in the case, a light source disposed in the case that emits light in accordance with an operation of the relay body, a light guide path which that receives, via a first end surface, the light emitted from the light source, and causes the light to exit outward from a second end surface, and a diffusion structure disposed in an optical path of the light which exits from the second end surface of the light guide path. | 08-20-2015 |
20150364283 | OPERATION INDICATING LAMP-EQUIPPED ELECTROMAGNETIC RELAY - An operation indicating lamp-equipped electromagnetic relay has an excitation coil, a contract member that has electromagnetic interaction with the excitation coil to open and close a circuit, a housing in which the excitation coil and the contact member are disposed, and having a display surface arranged in a top surface thereof, a light source having an optical axis that is oriented toward a direction other than the display surface in order to display an operating situation of the electromagnetic relay, and being disposed in the housing so as to emit light according to a situation of power supplied to the excitation coil, a reflecting member disposed in the housing so as to reflect the light emitted from the light source toward the display surface, and a diffusion structure that diffuses the light reflected by the reflecting member formed in the display surface. | 12-17-2015 |
20160069800 | REFLECTIVE SENSOR - The present invention includes an optical system disposed on an optical path of light that is emitted by a light emitting section, travels to a detection target object, is reflected by the detection target object, and reaches a light receiving section. The optical system, in a sub scanning direction, that is, the direction in which a detection target object is moving, collects light so that the light receiving section has, for light from the light emitting section, a regularly reflected light receiving area and a diffuse-reflected light receiving area that differ from each other in position within a predetermined range. The optical system, in a perpendicular direction that is perpendicular to the movement direction, refracts light so that a light receiving area, which covers the regularly reflected light receiving area and the diffuse-reflected light receiving area, is wider in the perpendicular direction than in the sub scanning direction. | 03-10-2016 |

20080200996 | PROCESS CONTROL APPARATUS - A process control apparatus for controlling a control target includes, but is not limited to, first and second control units. The first control unit is designed in a design environment unspecifying any period of disturbance. The first control unit performs a feedback control to the control target by using a setting value of the control target and a measured value of the control target. The first control unit is included in a feedback loop. The second control unit is also included in the feedback loop. The second control unit is designed by using an internal model principle. The second control unit rejects the disturbance, which is applied to the feedback loop, by using the measured value of the control target. | 08-21-2008 |

20110216267 | AREA LIGHT SOURCE DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - An area light source device has a light guide plate having a light incident surface and a light exit surface, wherein the light guide plate spreads light introduced from the light incident surface to substantially the entire light exit surface, and exits the light to outside from the light exit surface, and a linear light source arranged facing the light incident surface of the light guide plate. A diffusion pattern diffuses and reflects the light in the light guide plate within a surface parallel to the light incident surface is formed on the light exit surface of the light guide plate. A deflection pattern reflects the light in the light guide plate within a plane perpendicular to the light incident surface and the light exit surface to deflect the light in a direction perpendicular to the light exit surface little by little, and diffuses and reflects the light in the light guide plate within a surface parallel to at least the light incident surface is formed on a surface on the side opposite to the light exit surface of the light guide plate. | 09-08-2011 |
20130141669 | SURFACE LIGHT SOURCE APPARATUS - A light guide plate has a light incident surface configured to be arranged facing a point light source for introducing light from the point light source, a light outputting surface that outputs the light to an outside of the light guide plate, a light introducing section for confining the light from the point light source entered from the light incident surface, and a light guide plate main body having a thickness smaller than a maximum thickness of the light introducing section and being arranged to be continuous with the light introducing section, for outputting the confined light to the outside of the light guide plate from the light outputting surface by a light outputting element. | 06-06-2013 |

20140191657 | COAXIAL MAGNETRON - The object of the presently disclosed embodiment is to improve heat dissipation and an overall cooling efficiency to raise a peak oscillation output. To achieve the object, there is provided a coaxial magnetron having the following configuration: Around a cathode, vanes and an anode cylinder form an anode resonant cavity, and a cylindrical side body forms an outer cavity. An input side structure having an input part and an upper structure are joined to both ends of the cylindrical side body. One end of the anode cylinder is joined to the input side structure. A groove (or step) for adjusting the distance between the structures and at the both ends is provided, and the groove is joined to the other end of the anode cylinder. | 07-10-2014 |
