Abstract: A process for producing a modified coal from a coal of low-rank as a raw material includes dehydrating the coal, adding water to the dehydrated coal, agglomerating the water-added coal, and gradually oxidizing the agglomerated coal. In the water addition, an added amount of the water is regulated so that the water-added coal has a water content of 5% by mass or more and 20% by mass or less. In the oxidation, the agglomerated coal is held in an air at a temperature of 70° C. or more and 105° C. or less.

Abstract: A training system including: a training equipment provided with a movable portion for allowing an exerciser to perform an exercise; and an operation terminal for transmitting operation information for an action of the movable portion to the training equipment. The training equipment includes: an equipment-side receiver for receiving the operation information; and a driver for driving the movable portion in accordance with the operation information. The operation terminal includes: an input portion for allowing operation information to be externally inputted; a terminal-side transmitter for transmitting the operation information inputted in the input portion to the training equipment; a terminal-side display portion for displaying an image; and a terminal-side display controller for allowing the terminal-side display portion to display the operation information.

Abstract: A training apparatus comprises a seat 32 mounted on an apparatus body, a training mechanism disposed in front of the seat 32 and provided with a mechanism adapted to exercise legs of a user, a load-applying unit adapted to apply a braking force to a movement of the training mechanism in an electrically adjustable manner, and a tilt adjustment unit adapted to tiltingly move a front end of the seat in a vertical direction. The training apparatus of the present invention allows a user, even an elderly person or a person who requires assistance to readily sit on the seat without an unnatural or forced physical posture.

Abstract: Disclosed is a training apparatus, which comprises a seat unit 30 including a seat 35 allowing a user M to sit thereon, a foot plate 42 adapted to allow the user M sitting on the seat 35 to keep his/her feet bottoms in contact therewith, a displacement mechanism unit 38 adapted to apply to the user M a load against a straining force generated when the user M sitting on the seat 35 while keeping the feet bottoms in contact with the foot plate 42 strains his/her legs, and a base board 20 mounting thereon the above components. The foot plate 42 is adapted to be changed in posture between a horizontal posture T1 where it protrudes approximately horizontally and outwardly from a pair of footrest frames 41 mounted on the base board 20, and a vertical posture T2 where it protrudes approximately vertically and upward from the footrest frames 41 at approximately the same height level as a that of the seat 35.

Abstract: A permanent magnetic alloy essentially consists of 10 to 40% by weight of R, 0.1 to 0.8% by weight of boron, 50 to 300 ppm by weight of oxygen and the balance of iron, where R is at least one component selected from the group consisting of yttrium and the rate-earth elements.An alloy having this composition has a high coercive force .sub.I H.sub.C and a high residual magnetic flux density and therefore has a high maximum energy product.

Abstract: An electric braking control apparatus for the DC motor comprises; a DC power supply; a series circuit including the field winding and armature of a DC motor a smoothing reactor and a resistor connected to the DC power supply; a chopper connected in parallel to the series circuit, and a diode inserted between the DC power supply and the parallel circuit including the series circuit and the chopper. The field winding and the resistor are regulated in effecting regenerative braking of the DC motor by turning on and off the chopper.
