20100177285 | Optical scanning device, optical scanning image display device and retinal scanning display - An optical scanning device includes a light source which radiates light of intensity corresponding to an electric current supplied to the light source, an optical scanning part which is capable of scanning the light radiated from the light source in the predetermined direction, and a light source drive part which supplies a bias current of a predetermined current value to the light source and sequentially supplies an electric current corresponding to an image signal to the light source. The light source drive part stops or reduces the supply of the bias current to the light source during at least a predetermined period of an invalid scanning period where an image display is not performed. | 07-15-2010 |
20100177370 | Piezoelectric transducer element, actuator, sensor, optical scanning device, and optical scanning display device - In a piezoelectric transducer element, on a base body having a fixing part and a movable part which are connected with each other, a piezoelectric body which is sandwiched between a lower electrode and an upper electrode is formed in a state where the piezoelectric body extends between and over the fixing part and the movable part of the base body. The piezoelectric body converts a change in potential between the lower electrode and the upper electrode into mechanical displacement of the movable part relative to the fixing part or the mechanical displacement into the change in potential. The upper electrode includes a pad electrode for connection which is formed above the fixing part, and the lower electrode is not formed in a region above the fixing part and below the pad electrode. | 07-15-2010 |
20110012875 | IMAGE DISPLAY DEVICE - An image display device includes: a light blocking part arranged outside an effective scanning range within a light scanning range of an optical scanning part and including opening regions through which a portion of light scanned at a position outside the effective scanning range passes and a mask region which blocks remaining light; and a radiation part which radiates the light which passes through the opening regions out of the light scanned by the optical scanning part at the position outside the effective scanning range to the outside of the image display device. Corresponding to a state of the image display device, the opening region through which the light passes is decided out of the plurality of opening regions. Light is radiated from the light source part when a scanning position of the optical scanning part is positioned at least in the opening region decided in this manner. | 01-20-2011 |
20110075104 | RETINAL SCANNING DISPLAY - A retinal scanning display includes: a light source part which radiates a laser beam; a scanning part which scans the radiated laser beam in two dimensional directions; a projection part which projects the scanned laser beam on a retina of a viewer; a light detection part which is arranged at a position on which the scanned laser beam is incident; and a light blocking part which blocks the scanned laser beam scanned at the timing detection time; and a control part which controls the radiation of the laser beam based on the detected timing of the laser beam by the light detection part. The control part allows the light source part to radiate the laser beam at the timing detection time with intensity which exceeds a maximum value of intensity of the laser beam radiated from the light source part at the image forming time. | 03-31-2011 |

20110021909 | LEAK DETECTING APPARATUS - A leak detecting apparatus is provided which can detect leak of a liquid injected through an injection needle into a blood vessel of a human body near its surface with high accuracy. The apparatus emits a light ray in a predetermined wavelength band containing a particular wavelength at which the reflectivity for the liquid is lower than the reflectivity for internal tissues of the human body, to the human body at a position thereof where the injection needle is inserted, and detects the light ray in the wavelength band reflected inside the human body. The apparatus measures the average intensity of the detected light ray in the wavelength band and the intensity of the detected light ray at the particular wavelength to determine an occurrence of leak when the ratio of the intensity at the particular wavelength to the measured average intensity in the wavelength band is lower than a predetermined reference value. Variations in human body or physical condition affect the whole of the wavelength band but have no effects on the relative relationships between the wavelength band and the particular wavelength. Thus, the leak of the liquid can be detected without being affected by variations in human body or physical condition. | 01-27-2011 |
