  • Publication number: 20190219074
    Abstract: A transaxle includes a braking unit disposed in the transaxle casing, the braking unit configured to brake the axle. The braking unit includes an operating shaft projecting from one side of the transaxle casing. A link mechanism of the transaxle is includes a relay arm rotatably pivoted on a shaft provided on the one side of the transaxle casing, a brake arm fixed to the operating shaft, the brake arm being configured to rotate between a braking position and an unbraking position of the braking unit together with the operating shaft, a first link configured to manipulate the relay arm, and a second link configured to join the relay arm to the brake arm. The link mechanism constrains motion of the brake arm through the second link such that an external force on the braking unit cannot cause an unexpected release from the braking state.

  • Publication number: 20160243032
    Abstract: Biocompatible intraocular implants include a steroid and an auxiliary agent, where the auxiliary agent is present in an amount sufficient to lessen the severity of at least one side effect compared to the use of an otherwise identical implant lacking said auxiliary agent. The steroid and the auxiliary agent may be present on the same intraocular implant or on different implants. The steroid and auxiliary agent may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the steroid may be associated with a polymeric coating having one or more openings effective to permit the steroid to be released into an external environment. The implants containing the steroid and an auxiliary agent may be placed in an eye to treat one or more ocular conditions while reducing the side effects otherwise accompanying steroid use.
