Abstract: To provide an aircraft use water heater that operates by an aircraft power source of an AC variable frequency mounted in an aircraft, that is small, light-weight, safe, and low power consumption, and that can supply warm water stably. In an aircraft use water heater composed of a tank section for heating liquid stored therein and a controlling section for controlling the heating of the liquid by an aircraft power source, a bottom face of the tank section has a baffle plate and, liquid flowing in the tank section collides against the baffle plate to flow in a different direction parallel to the bottom face and is upwardly moved, while being heated, in the vicinity of a helical coil-type heater and is taken out through a liquid outlet.

Abstract: The invention aims at reducing the beating noise generated from motors of equipments placed in a galley unit of an aircraft. A galley unit 1 of an aircraft includes a cabinet 10 formed of honeycomb panels and the like. The cabinet 10 has a counter 50 for cooking, and a compartment 20 formed under the counter 50 for storing service carts 30. A plurality of ovens 100 for heating warm dishes are provided above the counter 50. Each oven 100 has a fan motor for making the inner heat even. If all the fan motors of the ovens are driven at the same rotation frequency, a beating noise will be generated from the motor and amplified through the compartment 20. Therefore, the rotation frequencies of the fan motors are slightly varied.

Abstract: An information service system comprises a portable unit carried by the user and an identification tag for supplying information on the present position of the user or the place where the user is approaching. The identification tag transmits the transmission information including the specified information stored in advance using infrared light or the like. The portable unit that has entered a predetermined range of the identification tag, upon receipt of the transmission information, demodulates the specified information and outputs the specified information from an information output unit such as a speaker. By the way, in the case where the specified information is an identification tag ID for specifying the particular identification tag, the portable unit selects the guide information corresponding to the identification tag ID through the portable unit controller and outputs it from the information output unit.

Abstract: A displacement measuring appparatus is small in size and hence capable of avoiding interference with other units and further has its measurement accuracy hardly deteriorated. There are disposed pulleys for movement with respect to the body of the appartus and there is disposed an energizing means such that the pulleys are subjected to the energizing force. A wire is passed around the pulleys. When the wire is subjected to a pulling force, the pulleys are moved against the energizing force of the energizing means.

Abstract: An apparatus for supplying start fuel for a carburetor in which an internal combustion engine has a fly-wheel with a magneto incorporated therewith. An intake air passage has an electromagnetic valve and this valve is actuated by an output signal of a primary coil of the fly-wheel magneto. In one embodiment, the electromagnetic valve is actuated by an output difference between an output signal of a primary coil produced when a start motor is rotated and an output signal of the primary coil produced when the engine is rotated.

Abstract: A liquid metal cooled fast breeder reactor which permits a closer installation of a fuel handling mechanism relative to an upper reactor core structure of the reactor. The fuel handling mechanism has a fuel handling body without a housing, and has a rotational driving device on a rotating plug of a shield plug device of a reactor vessel. The fuel handling mechanism has an aseismatic support extending outwardly from the upper reactor core structure. The fuel handling mechanism is supported, at its upper portion, by the rotational driving device, and secured, at its lower protion, by the aseismatic support.
