Abstract: A vehicle-to-vehicle communication device mounted in a subject vehicle includes (i) a transmitter-receiver for communication with other vehicle-to-vehicle communication devices mounted in other vehicles, (ii) a memory that stores communication wavelengths assigned to the other vehicles, and (iii) a communication control unit. When a certain vehicle is determined to be within a dangerous distance from the subject vehicle, the communication control unit refers to a communication wavelength assigned to the certain vehicle stored in the memory. When the communication wavelength assigned to the certain vehicle is identical to a communication wavelength assigned to the subject vehicle, the communication wavelength assigned to the subject vehicle is changed to another communication wavelength different from the communication wavelength assigned to the certain vehicle.

Abstract: A rotary cutting tool which is to be rotated about an axis thereof for cutting a workpiece, including: a generally cylindrical body portion having (a) at least one flute each of which is formed in the cylindrical body portion and each of which extends from an axially distal end of the cylindrical body portion toward an axially proximal end of the cylindrical body portion, and (b) at least one cutting edge each of which is provided by one of widthwise opposite edges of the flute, wherein each of at least one cutting edge includes a corrugated edge portion having a corrugated shape, and wherein at least one of a pitch and a depth of the corrugated shape is increased with an increase in a diameter of the cylindrical body portion whose outer circumferential surface is defined by a rotary trajectory of an envelope passing through crests of the corrugated shape.

Abstract: An IC card reader-writer is integrated with a battery pack 15. This IC card reader-writer 16 has a control terminal CNT and a power supply control switch 30. A portable phone unit sends power-on/off signals, which are received by the control terminal CNT to turn on and off the power supply control switch 30 to control power supply from the battery 18 to the IC card reader-writer 16. The CPU 24 of the IC card reader-writer 16 controls power supply in such a manner that power is supplied to the IC card 22 only when access to the IC card 22 is necessary and stopped when access to the IC card 22 is unnecessary.

Abstract: A process for manufacturing a fluid, including the steps of punching spout or outlet plug fitting holes in both a plate of a tubular blank of the carton and a plastic film constituting the internal bag at a predetermined place where a spout or outlet plug is attached to the tubular blank and the internal bag, the tubular blank containing the plastic film and having a closed bottom wall, fitting the spout or outlet plug in the spout or outlet plug fitting holes from inside the tubular plug, and welding the spout or outlet plug to the plastic film.

Abstract: A container comprising a tubular body part having a longitudinal lapped side seam and a bottom part attached to one end thereof, characterized in that the overlapping portions of the side seam are adhered by ultrasonic bonding to provide a bonded area longitudinally of the side seam of predetermined transverse width throughout the major portion of its length and a bonded area at the top of greater transverse width which is at least several millimeters in length longitudinally of the seam.

Abstract: A device for forming the body and bottom of a container of the kind wherein there is an axial seam formed by adhesively-joined overlapping portions of the side and a bottom formed by an upwardly-folded lower end portion of the bottom adhesively enfolded within a downwardly-folded portion of the lower end of the side, said device comprising an ultrasonic side seaming device for welding the side seam, said side seaming device embodying an elongate, ultrasonic horn and means therein defining a planar contact surface containing a stepped-down recess commencing several millimeters from one end for engagement with the side seam and a bottom seaming device comprising an outer mold containing a mold cavity for receiving the bottom, said outer mold containing a centrally-located circular hole, a shaft, a knurling tool supported by the shaft within the mold cavity for rotation about its axis and movement circumferentially within the hole and means circumferentially of the knurling tool defining a circumferential wall a
