  • Linear light source apparatus and image reading apparatus
    Patent number: 8928955
    Abstract: A linear light source device illuminates a document properly, and an image reading device includes such a light source device. The light source device includes a light source and a light-guiding member. The light-guiding member introduces the light emitted from the light source from one end portion in x-direction, cause the light to travel in x-direction, and emits the light from a light exit portion at one end in z-direction, which is orthogonal to x-direction. The light-guiding member includes, at the other end in z-direction, a light-reflecting portion that reflects light to the light exit portion. One end face of the light-guiding member in y-direction, which is orthogonal to x- and z-directions, is inclined so as to become closer to the other end face in y-direction with decreasing distance from the light exit portion in z-direction. This allows light to easily travel to the light-reflecting portion.

  • Method for replenishing tin and its alloying metals in electrolyte solutions
    Patent number: 8920623
    Abstract: Methods are disclosed for replenishing tin and its alloying metals in an aqueous electrolytic plating bath using an acidic solution containing stannous oxide. During electroplating of tin or tin alloys the stannous ions and alloying metal ions are depleted. To maintain continuous and efficient electroplating processes predetermined amounts of the plating bath containing tin and its alloying metals are bailed out. The bail out is then mixed with a predetermined amount of acidic solution containing stannous oxide and any alloying metals. The mixture is then retuned to the plating bath to return the stannous ions and alloying metal ions to their steady state concentrations.

  • Control circuit for light emitting apparatus
    Patent number: 8922138
    Abstract: A first driver switches on and off a driving current ILED according to a first pulse signal which is pulse-width modulated according to an externally supplied target luminance level of a light emitting element. An oscillator generates a cyclic signal SOSC having a predetermined frequency. A pulse modulator generates a second pulse signal which is switched to an on level that corresponds to the on state of a switching transistor in synchronization with the cyclic signal SOSC, and which is switched to an off level that corresponds to the off state according to a feedback voltage. A second driver switches on and off the switching transistor according to the second pulse signal. The oscillator is configured to be reset according to a first edge which is transition of the first pulse signal from a first level that corresponds to the off state to a second level that corresponds to the on state.

  • Two-dimensional photonic crystal surface emitting laser light source
    Patent number: 8923358
    Abstract: A two-dimensional photonic crystal surface emitting laser light source includes a two-dimensional photonic crystal made of a plate-shaped body material provided with a periodic arrangement of identically-shaped holes and an active layer. The hole is not located on a first half-line extending from the gravity center of the hole, while the hole is located on a second half-line extending in the direction opposite to the first half-line. Injecting electric charges into the active layer generates light, which creates an electric field encircling the gravity center. For a given point on the second half-line where the hole is located, there is no hole at a point that is symmetrical to the aforementioned point with respect to the gravity center, so that the electric field vectors at the two points do not cancel each other and the laser light is stronger than conventional examples.
