    摘要： An endoscope apparatus includes an endoscope body and an air-/liquid-supply device connected thereto. Provided at the distal end of an insertion section of the body are an observation window and a nozzle directed toward the window. Air and liquid supply pipes extend from the nozzle, through the endoscope body. The supply device has a tank for storing water therein. The inside space of the tank is divided by a partition plate into a first chamber on the water side and a second chamber. Compressed air supplied from a first pump to the inside space is supplied to the air supply pipe through a first supply pipe, and compresses the water in the tank, thereby supplying the water to the liquid supply pipe through a second pipe. Air having a pressure higher than that of the first pump is supplied from a second pump to the second chamber. The high-pressure air is prevented from flowing into the first chamber, and is immediately supplied to the air supply pipe.

    摘要： An operational remote controller integrates a joystick for bending a bending portion of an inserted portion in an endoscope. A bending lever stands on the joystick. For every automatically returning of the bending lever to a neutral position, a CPU of the operational remote controller detects the neutral position and sets an insensitive band within a predetermined range of the neutral position. Thus, the insensitive band can be set within a relatively narrow range irrespective of variation of neutral positions. The CPU supplies positional information of the bending lever to a control circuit for controlling a motor drive circuit. The control circuit controls a motor drive circuit based on the supplied positional information, and the motor drive circuit drives a motor to bend the bending portion of the inserted portion.

    摘要： A fluid control valve, which can control a fluid having a pressure in the order of 10 kg/cm2, has a response time in the order of several milliseconds can be made small in size, and a fluid supply/exhaust system that provides less gas counter flow in the event of a plurality of valves being used. A fluid control valve of the invention controls a fluid moving in a valve body by closing and opening a portion between a valve seat and a valve holder by use of a drive unit. The drive unit has a rod-shaped shaft for application of pressure through the valve seat and the valve holder, and a member “a” fixed around the rod-shaped shaft. The member “a” is made from a magnetic material, and has a space between it and the shaft. A coil provided in parallel to the shaft, moves the shaft via the member “a” up and down by electromagnetic induction, and makes use of a spring force to close and open a portion between the valve seat and the valve holder.
