A communication apparatus performing communication in a noncontact manner is provided. The communication apparatus includes a transmission control unit configured to transmit a command; a timeout period checking unit configured to check whether a timeout period during which a response to the command is waited for has elapsed; a retransmission control unit configured to retransmit the command only after the timeout period has elapsed; an error checking unit configured to check whether data received within the timeout period has an error; and a processing unit configured to regard the data received within the timeout period as a correct response to the command if the data does not have an error and perform a process in accordance with the response. If the data received within the timeout period has an error, the retransmission control unit does not retransmit the command and the timeout period checking unit continues to check whether the timeout period has elapsed.

According to a PLL circuit of the present invention, an output of a phase comparator is adjusted according to a space-to-mark transition-probability of an input signal so that an output of a voltage controlled oscillator has a predetermined frequency and phase. Therefore, even when a phase of a timing clock is set other than at 0, an output of the PLL circuit can be kept at the set phase, irrespective of the space-to-mark transition-probability. By using the PLL circuit as such in an optical communication apparatus and an optical communication system, a discrimination point can be kept almost fixed, and therefore, it is possible to lower an error rate.

The automated solution injection-discharge system is used as an APDS system to supply and discharge a dialysate and a patient's drain. And an automated solution injection-discharge system provides free of contamination and operation mistakes, and can accurately control the injected dialysate volume and the discharged dwell solution volume even when a patient does not maintain a fixed posture while replacing the solution.

In an embodiment, a CO2 recovery system has an absorber, a regenerator, and a circulation device. An absorption liquid has an aqueous solution of amine having an alcohol group, and dimethyl silicone oil in which a part of methyl groups is substituted by at least one type selected from an aminoalkyl group, a carboxyl group, and a hydroxyl-containing alkyl group. The absorber contacts a combustion exhaust gas of a fossil fuel and the absorption liquid to absorb CO2, which is contained in the combustion exhaust gas, into the absorption liquid. The regenerator releases CO2 by applying thermal energy to the CO2-absorbed absorption liquid. A circulation device circulates the absorption liquid between the absorber and the regenerator.

In one embodiment, a steam device includes a high-temperature member and a low-temperature member. One surface of the high-temperature member is exposed to high-temperature steam, and the other surface is cooled by cooling steam having a temperature lower than the high-temperature steam. The low-temperature member is disposed to face the high-temperature member with a passage for the cooling steam therebetween and is formed of a material having a heat resistance lower than that of the high-temperature member. The steam device has at least one high-reflectance film selected from a first high-reflectance film, which is formed on the surface of the high-temperature member which is exposed to the high-temperature steam and has a higher reflectance with respect to infrared rays than the high-temperature member, and a second high-reflectance film, which is formed on the surface of the low-temperature member facing the high-temperature member and has a higher reflectance with respect to infrared rays than the low-temperature member.

A plurality of blades are studded in a rotor disc integrated with the rotor along the circumferential direction of the rotor, a plurality of vanes are attached to a casing covering the rotor along the circumferential direction of the rotor, and an internal diaphragm disposed on rotor-side surfaces of the vanes in such a way that the internal diaphragm faces the rotor disc. The vanes and the blades adjacent to each other in the axial direction of the rotor form a turbine stage. A rotor-side cooling path is formed through the rotor disc in the axial direction of the rotor, and a diaphragm-side cooling path is formed through the internal diaphragm in the axial direction of the rotor, and a cooling medium flowing through the rotor-side cooling path diverts into the diaphragm-side cooling path and a labyrinth flow path provided between the internal diaphragm and the rotor.
