Abstract: An internet of things (IoT) connection system comprises an IoT hub including first processing circuitry, and a local IoT router including second processing circuitry. The local IoT router is connected to the IoT hub via a network. The first processing circuitry is configured to execute a first driver to connect the IoT hub to a private cloud to which a first device is to connect, and execute a second driver to connect the IoT hub to a second device. The second processing circuitry is configured to execute a third driver to connect a third device to the IoT router. The first driver, the second driver and the third driver are generated according to only device definitions and command definitions.

Abstract: A method for brazing two or more of stainless steel components for use in medical equipment, in which one component is joined to other component using a brazing material containing Au of which amount is 62.5 wt % or higher, the method comprising the steps of: a first step in which the components are subjected to a heat treatment at a temperature of 1,050 to 1,200° C. in a hydrogen containing atmosphere or in a vacuum; a second step in which one of the components is allowed to close to the other component so as to form a gap therebetween; and a third step in which the brazing material in a molten state is supplied into the gap to join the components together to manufacture a metal assembly. The joint portions formed in the metal assembly have excellent chemical resistance and corrosion resistance, and thus the metal assembly is suitably used in an endoscope.

Abstract: At the tip of an insert portion of an endoscope, LEDs are provided. An air and liquid supply unit is mounted on a handle portion of the endoscope. The air and liquid supply unit is provided with a tank, a pump, and a battery. Liquid, which is supplied to the tip, is stored in the tank. The battery supplies driving current to the pump and the LEDs. The pump takes in the surrounding air. In accordance with the manipulation of the buttons provided on a grip portion of the endoscope, the pump sends either the liquid or the air to the tip.

Abstract: A portable endoscope having a probe which is inserted into a human body, comprises a tank, a flexible tube, a pump, and a weight. The flexible tube is provided to supply liquid to the tip of the probe from the tank via a connection and a nozzle. The weight is provided to bend the flexible tube so that one end of the flexible tube, inside the tank, reaches the liquid regardless of the angle of inclination. A liquid and air supply unit for the endoscope is provided with the tank which stores liquid or cleansing water.

Abstract: A treatment instrument includes a first coil and a second coil that is different from said first coil. The first and second coils are connected to each other. An operation wire is inserted in the first and second coils, and a tip end of the wire is connected to a treatment device. Upon movement of the wire, the treatment device operates. A method of manufacturing such a treatment instrument includes inserting one end of the first coil and one end of the second coil in a connection pipe from opposite ends thereof, exposing both ends of the connection pipe and corresponding portions of the first and second coils. The portions exposed to the arc columns are melted and connected.

Abstract: A television device of a portable endoscope includes an endoscope including an inserted portion and an operating portion coupled to a base end of the inserted portion, a light source for lightening a subject through the inserted portion provided in the endoscope, a radio transmission television camera for obtaining an image of the subject through the inserted portion and radioing the image as the video signal provided in the endoscope, and a power source, which supplies a power for the light source and the radio transmission television camera, provided in the operating portion.

Abstract: There are provided a process for forming a silicon nitride sintered body, encompassing a sialon sintered body, by making much of the superplasticity of the sintered body intact as a simple material without formation thereof into a composite material, and a formed sintered body produced by the foregoing process. A silicon nitride sintered body (encompassing a sialon sintered body) having a relative density of at least 95% and a linear density of 120 to 250 in terms of the number of grains per 50 .mu.m in length in a two-dimensional cross section of the sintered body is formed through plastic deformation thereof at a strain rate of at most 10.sup.-1 /sec under a tensile or compressive pressure at a temperature of 1,300 to 1,700.degree. C. The formed sintered body has a degree of orientation of 5 to 80% as examined according to a method specified by Saltykov, a linear density of 80 to 200, and excellent mechanical properties especially at ordinary temperatures.
