Abstract: A hydraulic arrangement for controlling the tilt and trim of an outboard drive. The hydraulic arrangement comprises a single cylinder assembly having a single bore inside wherein two separate pistons are supported for reciprocation and sealed to the cylinder with piston seals. The lower piston is connected to a valve mechanism that selectively opens or closes a cylinder relief hole depending upon the position of the piston within the cylinder. The valve mechanism operates so that the piston seals never contact the relief hole to prevent premature failure of the piston seals.

Abstract: A laser probe including an optical fiber for guiding a laser beam, a holder fixed at an end portion of the optical fiber, and a reflection tip detachably attached to the holder and having a reflection surface for reflecting the laser beam emitted from the optical fiber.

Abstract: A fluorescent endoscope apparatus having: an endoscope that irradiates a subject portion to be observed with light transmitted through a light transmission device to obtain an object image of the subject portion to be observed; a normal observation light generating device for emitting normal light for performing normal light endoscope observation; a fluorescent observation light generating device for emitting excitation light for performing fluorescent light observation; an introduced-light switching device for selectively introducing, to the light transmission device of the endoscope, normal light emitted by the normal observation light generating device or excitation light emitted by the fluorescent observation light generating device; and an image sensing device for capturing a normal light image of the subject portion to be observed that can be obtained by irradiating the subject portion to be observed with normal light or excitation light or a fluorescent image that can be obtained due to irradiation wit

Abstract: A hydraulic tile and trim mechanism for a marine outboard drive that provides a compact assembly and which ensures that contaminants which may enter the hydraulic fluid can accumulate in the fluid reservoir and will not be circulated by the fluid pump. This is accomplished by positioning the reservoir below the fluid pump and using a pick-up tube that does not extend into the bottom of the reservoir so that the contaminants can accumulate therein without being circulated.

Abstract: A telescopic tilt and trim arrangement for an outboard drive that has a compact configuration made possible by positioning the seal between the trim cylinder and the outer cylinder at the upper end of the trim cylinder. In addition, a latching arrangement is incorporated between the trim cylinder and the outer housing for holding the trim cylinder in its fully trimmed up condition when the outboard drive is tilted up.
