  • Patent number: 10446838
    Abstract: Cycle characteristics of a nonaqueous secondary battery are to be improved. An active material including: a first active material that contains a nano silicon produced by heating a layered polysilane represented by a composition formula (SiH)n and having a structure in which multiple six-membered rings formed from silicon atoms are connected; and a second active material that contains a graphite, is used in a negative electrode. With this, expansion and contraction due to stress during charging and discharging can be mitigated, and thereby cycle characteristics improve.

  • Patent number: 8915843
    Abstract: A light source apparatus for an endoscope, which has a lamp, a power source, a light adjustment control module that controls power to be supplied to the lamp within a range not more than an upper limit power based on a brightness instruction signal, and a continuous lighting sensing module that measures a continuous lighting time period from time when the lamp shifts from being extinguished to being lighted, compares the continuous lighting time period with a predetermined upper limit time period, and initializes the continuous lighting time period while the lamp is extinguished, wherein the upper limit power is set to a first upper limit power when the continuous lighting time period has not reached the upper limit time period, and changed to a second upper limit power lower than the first upper limit power in a stepwise manner when the upper limit time period has not been reached.

  • Patent number: 8066409
    Abstract: A light source device includes a light-condensing device that condenses an illumination light that is emitted from a light source lamp. The light-condensing device includes at least one lens, a lens holder in which a lens is fixedly provided, and a lens holding member. The lens holding member is a member for fixing a lens to the lens holder. The lens holding member causes at least one circumferential portion of the lens to protrude to the lens holder side, and causes the optical axis of the lens to match the optical axis of the illumination light.

  • Patent number: 7789532
    Abstract: A light source device includes a light source lamp, a rotary plate, a heat absorbing portion, and a filter mounting member. The light source lamp emits illumination light. The rotary plate includes multiple opening portions that are selectively disposed in the illumination light path of the light source lamp. A reflective filter that reflects light of a wavelength that acts a heat source in illumination light is provided in one of the multiple opening portions of the rotary plate. The heat absorbing portion absorbs heat included in reflected light reflected by the reflective filter in the opening portion. The filter mounting member disposes the reflective filter in the opening portion at a predetermined angle of inclination to the optical axis of the illumination light. By disposing the inclined reflective filter in the illumination light path, reflected light reflected by the reflective filter is reflected towards the heat absorbing portion.
