  • Publication number: 20240248384
    Abstract: A light source device includes a light source element that emits light source light in a first wavelength region, a selective reflection element that separates the light source light into first light and second light, a first light direction conversion element that reflects the first light guided in a first direction from the selective reflection element in a second direction, and a wavelength conversion element that converts the first light into third light in a second wavelength region. The first light direction conversion element reflects the third light in a third direction opposite to the first direction. The selective reflection element transmits the third light reflected by the first light direction conversion element. The selective reflection element guides the second light and the third light in the third direction. The light source element emits the light source light in a direction different from the second direction.

  • Patent number: 11441094
    Abstract: A booster additive concentrate may advantageously contain: (a) an anti-wear mixture of two or more phosphite/phosphate compounds and one or more ether/thioether compounds; (b) an ashless dispersant; (c) a calcium-containing detergent, such as an overbased calcium phenate; (d) ?2 friction modifiers, at least one of which comprises a polyalkylene polyamine succinimide derivative; (e) optionally a corrosion inhibitor; and (f) a lubricating oil basestock. Based on these additive components, the booster additive concentrate may exhibit specific contents of B/Ca/P and may contain minimal or substantially no additional antioxidants. Lubricant compositions can be made from the booster additive concentrates and a fresh/used lubricant oil composition “diluent,” which can rejuvenate the diluent. Such lubricant compositions can have advantageous anti-shudder durability (ASD) lifetimes and other frictional properties.
