  • Patent number: 11467261
    Abstract: A distance measuring device that measures a distance to an object. The distance measuring device includes: a light source that emits pulsed light; a reflector that reflects and radiates, as radiation light, the pulsed light emitted from the light source, and reflects object light that is the radiation light reflected by the object and returning; and an imager that captures the object light reflected by the reflector. The pulsed light emitted from the light source is diffused light. The light source and the imager are located to face the reflector. The reflector radiates, as the radiation light, light in a shape with a long axis and a short axis. The imager performs exposure in synchronization with the pulsed light to image the object light.

  • Patent number: 8722129
    Abstract: The invention provides a method for efficiently improving emulsifying ability of gum arabic, in other words, a method for producing gum arabic with excellent emulsifying ability. Further, the present invention provides a method by which a gum arabic modified so as to have a high emulsifying ability can be obtained without involving the problem of forming syrupy masses or sticking to the vessel or the trouble of excessive dehydration or charring. The above-described methods can be carried out by heating gum arabic (unmodified) under dry conditions. Preferably, the method is carried out by heating gum arabic in such a manner that the loss-on-drying is not more than 3%.
