Abstract: A communication system according to the present invention includes a plurality of terminal devices that are able to communicate mutually. Each of the terminal devices includes a voice input conversion device, a voice transmitting device, a voice receiving device, and a voice reproducing device. When there is a plurality of voice signals which has not been completed reproduction, the voice reproducing device reproduces after arranging the voice signals so that respective voices corresponding to the respective voice signals do not overlap.

Abstract: A receiver of the present invention includes a microphone, an unnecessary signal remover, and an FM detector. The microphone receives a transmission signal generated by frequency modulating a signal in a frequency band that is receivable by the microphone, on the basis of transmission data. The unnecessary signal remover removes unnecessary signal components by processing the received signal from the microphone. The FM detector restores transmission data by performing FM detection of the received signal from which unnecessary signal components were removed by the unnecessary signal remover.

Abstract: A system for controlling pouring machines, equipment for pouring molten metal using the system and a method of pouring the molten metal where the molten metal can be smoothly poured by the coordinated operation of a casting machine having a first automatic pouring machine and the second automatic pouring machine. The system for controlling the pouring machines has a main control device, a control device for controlling the first pouring machine, and a control device for controlling the second pouring machine so that the operations of two automatic pouring machines are controlled and a smooth coordinated operation of the two automatic pouring machines is realized so that the automatic pouring machines can pour the molten metal into each of a number of molds of a casting line for molds.

Abstract: A vehicle includes a detection device and a color change device. The detection device detects an internal state and an external state of the vehicle. The color change device at least partially changes a color of a body of the vehicle depending on a result of detection by the detection device.

Abstract: The present invention is to provide a system for controlling pouring machines, equipment for pouring molten metal using the system and a method of pouring the molten metal where the molten metal can be smoothly poured by the coordinated operation of a casting machine and two automatic pouring machines, where the automatic pouring machines pours the molten metal into each of a number of molds of a casting line for mold. The first automatic pouring machine comprises a first carriage that can run in the direction of the molds of the casting line for mold and a first pouring ladle that is attached to and transported by the first carriage and the second automatic pouring machine comprises a second carriage that can run in the direction of the molds of the casting line for mold and a second pouring ladle that is attached to and transported by the second carriage.

Abstract: In a charging fee billing system according to the invention, a preferential card having preferential information stored thereon is issued, the preferential information allowing for an investor having borne costs required for power storage facilities for use in a commercial power system to receive a discount for electricity fees involved in the charging of an electric automobile. When charging is performed for an electric automobile that is equipped with a preferential card, a charging unit set up at a charging stand acquires preferential information from the preferential card. The charging unit bills a charging fee to which a preferential rate has been applied based on the preferential information acquired from the preferential card.

Abstract: A method for working a nut screw for a ball screw has a first step of lathing or cutting a spiral-shaped rolling surface of the nut screw for a ball screw on which balls of the ball screw are allowed to roll, a second step of heat treating, for example, carburizing and quenching or high-frequency quenching the spiral-shaped rolling surface obtained in the first step to thereby harden the top surface layer of the rolling surface and, a third step of surface finishing the hardened top surface layer of the spiral-shaped rolling surface obtained in the second step according to an electrolytic polishing.

Abstract: An electric dry shaver with an inner blade block including a parallel array of semiconductor shearing blades and reciprocally driven along inner surface of a flexible thin outer blade mounted substantially in a semicylindrical shape of an outer blade block by means of a vibrating device through a reciprocal driving shaft detachably and resiliently connected to a connecting means pivotably provided in the inner blade block substantially at the center of gravity thereof. The connecting means is pivoted to the inner blade block at an axis passing substantially the center of gravity and intersecting at right angles longitudinal axis of the semicylindrical outer blade in a plane perpendicular to a plane including reciprocal directions of the driving shaft and the connection of the driving shaft to the connecting means is performed at a position adjacent the pivoting axis of the latter.
