According to one embodiment, there is provided pressure controlling apparatus including a detecting unit, an exhaust pipe, a regulating valve, and a pressure controlling unit. The regulating valve includes a valve port, a changing unit, and a slide valve. The valve port is communicated with the exhaust pipe. The changing unit changes a shape of the valve port to a different shape whose center is located near the central axis of the exhaust pipe. The slide valve regulates an opening degree of the valve port changed by the changing unit. The pressure controlling unit controls changing of a shape of the valve port by the changing unit and regulation of an opening degree of the valve port by the slide valve.

According to an embodiment, a plasma treatment apparatus includes a processing target holding unit and a plasma generation unit in a chamber. The processing target holding unit includes a supporting table on which a wafer is mounted, a ring-shaped insulator ring arranged at an outer periphery of the supporting table, and a protective film containing yttria for covering a side surface section and an upper surface section of the insulator ring. The protective film is formed thicker on the upper surface section than on the side surface section of the insulator ring.

An antigen measuring device has an antibody chip. The antibody chip has a substrate. A pair of gratings are formed on the substrate. An antibody-fixed layer surrounded by a wall is formed between the gratings. A light emitting element emits a light beam toward the first grating. A light receiving element receives the light beam which propagates through the substrate under the antibody-fixed layer and is outputfrom the second grating.

According to one embodiment, there is provided a plasma treatment apparatus including an electrode, a first power supply circuit, a plasma generating unit, a second power supply circuit, a sensing unit, and a control unit. The electrode is arranged inside a treatment chamber. On the electrode, a substrate to be treated is placed. The first power supply circuit supplies power to the electrode. The plasma generating unit generates plasma in a space separated from the electrode inside the treatment chamber. The second power supply circuit supplies power to the plasma generating unit. The sensing unit senses a parameter output from the first power supply circuit. The control unit controls power supplied from the second power supply circuit so that the parameter sensed by the sensing unit becomes close to or substantially equal to a target value.
