摘要： A lip type end face sealing device having excellent sealability to different kinds of liquids on both sides in the axial direction and having excellent durability. A case is tight fitted to an inner peripheral face of a housing and includes case members. One pair of seal lips is integrally fitted to inner peripheral flange parts, positioned oppositely each other in the axial direction, and opened in a tapered shape. One pair of the seal lips is slidably contacted with flange parts of slingers tight fitted to an outer periphery of a rotary shaft. Pressure in seal internal spaces between the seal lips is released through a vent hole.

摘要： An endoscope device is proposed for dealing with an erroneous operation of a surgeon. An endoscope device has an endoscope and a processor, wherein the endoscope has a switch unit and the processor has a CPU and an operating panel. In the event that the CPU of the processor detects that, of a first instruction signal transmitted from the switch unit and a second instruction signal transmitted from the operating panel, the instructions for performing the predetermined operation are not performed normally with one of the instruction signals, and instructions for performing an operation other than the predetermined operation is performed normally with the other instruction signal, the CPU stops the transmission of one of the instruction signals, and validates the operation content instructed by the other instruction signal.

摘要： A cavity insert device comprising an insert section capable of being inserted into tracts and cavities, a detection circuit for detecting conditions of components making up the device, such as an observation device formed at the distal end side of the insert section, and a fuzzy inference section for synthetically determining a plurality of information signals outputted from the detection circuit and producing control signals to control the components. The fuzzy inference section employs inference rules which are empirically considered to be desirable, and control is made by the control signals obtained with the fuzzy inference. The device is thus operated in a nearly optimum state.
