Abstract: A train information management device sends and receives information to and from both a train-controlling in-vehicle wireless station for controlling an operation of a train, and a door-controlling in-vehicle wireless station for controlling vehicle doors. The device includes a wireless train control unit, an automatic operation unit, and a door control unit. The wireless train control unit receives route information represented by a consecutive block sequence and information on a stop limit location that the train may reach without hindering a preceding train, and if this route information includes a station block number, consults an in-vehicle database to extract, before the train arrives at a platform, an arrival track where the train is to stop, a stop target location at a stop station dependent on a travel direction of the train, and which of the vehicle doors is to be opened, and stops the train in accordance with the route information.

Abstract: A train wireless system includes a train detecting apparatus on the ground and a controller on a train. The detecting apparatus includes a detector and a calculator. The detector detects that the train is on rails in a block. The calculator measures an on-rail time during which the detector detects the train in the block, and calculates an on-rail detecting time during which the train has been on the rails in the block. The controller includes a distance measurer, a time measurer, a recorder, and a train-length calculator. The distance measurer measures a travelling distance of the train from a beginning of the block, the time measurer measures an elapsed time since the distance measurer starts the measurement, the recorder records the elapsed time and the travelling distance, and the train-length calculator searches the recorder based on the detecting time, and calculates the train length using a selected travelling distance.

Abstract: A resin is irradiated with an infrared ray, and a reflected ray from the resin irradiated with the infrared ray is received. In a reflection or absorption spectrum obtained by the reflected ray, a difference of a reflection intensity in a spectrum between a first wave number band of 1340 cm?1 to 1350 cm?1, inclusive, and a second wave number band of 1300 cm?1 to 1340 cm?1, inclusive, is calculated. It is determined whether or not a specific bromine-based flame retardant is contained in the resin, by using the calculated difference of reflection intensity in the spectrum.

Abstract: At a conveyor forefront portion, velocity distribution of an airflow is provided. The velocity distribution is wind velocity distribution in a vertical direction of an airflow from a surface of an upper rectifying plate to a surface of a conveyor at the conveyor forefront portion, and has a maximum value in a range of less than 10 mm downward of the vertical direction from the rectifying plate surface. Moreover, a ratio obtained by dividing the maximum value by a wind velocity in the vicinity of the surface of the conveyor is 4 or more, and 12 or less. In a range other than the range of less than 10 mm, the airflow has a wind velocity equal to the wind velocity in the vicinity of the surface of the conveyor.

Abstract: An impeller element includes a plurality of blades disposed along an outer circumference of a circular support plate. Each blade is divided into a plurality of blade sections in a rotational axis direction. At least one of the divided blade sections as a long-chord blade section is configured such that a chord as a line segment connecting a blade outer-circumferential edge and a blade inner-circumferential edge of the blade in a cross section perpendicular to a rotational axis of the blade has a greater length than a chord of another one of the blade sections as a short-chord blade section. The blade inner-circumferential edge of the at least one long-chord blade section having the longer chord protrudes toward the inner circumferential side, relative to the blade inner-circumferential edge of the at least other one of the blade sections as the short-chord blade section having the shorter chord.

Deflectors are provided in the air-conditioning apparatus main body. An outlet airflow blown from each fan extension of the cross flow fan impinges upon a corresponding one of the deflector. Furthermore, the shape of blade portions of the fan extensions of the cross flow fan and the shape of blade portions opposing the air outlet are different from each other. The wind speed of the outlet airflow blown from the blade portion is lower than the wind speed of an outlet airflow blown from the blade portion.
