  • Publication number: 20110261685
    Abstract: A radio communication system provides a first call type in which a radio resource is allocated to a call in time division and a second call type in which the radio resource is allocated according to a transmission rate. The radio communication system includes a measurement unit measuring a usage result of the first call type and a usage result of the second call type; and a setting unit setting a first usage result priority level as a priority level of the first call type based on the usage result of the first call type upon receipt of the first call type and setting a second usage result priority level as a priority level of the second call type based on the usage result of the second call type upon receipt of the second call type. The first usage result priority level is applied independently of a congestion state of a radio communication section. The second usage result priority level is applied according to the congestion state of the radio communication section.

  • Patent number: 8001723
    Abstract: The present invention is to provide a technology capable of planting seedlings in soil in planting ground such as dry land and allowing the seedling to root securely and grow without artificially supplying water continuously. Not only is a seedling fixed inside an upper opening portion of a tube having a length to a deep water-containing layer in the planting ground but also a growing medium is put inside the tube at a hardness that allows the root of the seedling to grow long downward, and the root of the seedling is allowed to grow below the tube, thereby obtaining the seedling having a long root. A vertical hole having approximately the same diameter as that of the tube is dug in the ground of the planting ground until reaching a soil layer having water quality and water quantity necessary for growth of plant, the seedling having the long root is buried in the vertical hole together with the tube, thereby planting the seedling in the planting ground.

  • Publication number: 20080010807
    Abstract: The invention presents a method of manufacturing a multi-pitch screw having desired threads and pitches by rolling. A trace of general (even lead angle) spiral screw is formed by even pitch protrusions 610 and 620 of an existing rotating dies 61 and 62, and it is combined with a trace of stair step screw formed by stair step protrusions 632 of a rotating die 63 of uneven lead angle, and multi-pitch screw threads are formed efficiently. Herein, only one rotating die 61 of uneven lead angle is used, and screw threads are not flattened out by stair step protrusions of the plurality of rotating dies of uneven lead angles.

  • Publication number: 20070264100
    Abstract: To present a method of manufacturing a multipitch screw easily by using flat dies suited to mass production. A flat die 4 includes linear ordinary screw threads 40a, and multipitch screw threads 40b consecutive to the ordinary screw threads 40a, slightly shorter in height than the ordinary screw threads 40a, with both side walls formed alternately and consecutively, alternating between a section departing from the central line 40c of screw threads and an approaching section along a central line 40c, and symmetrically to the central line 40c of screw threads. After forming the tacks of a constant lead angle screw on the outer circumference of a shaft-like blank piece by the ordinary screw threads 40a, tracks of a multipitch screw are formed by the multipitch screw threads 40b, and therefore the tracks of a multipitch screw varying in the force applied at the time of rolling can be formed easily.

  • Patent number: 7246979
    Abstract: A flat portion 12a and a slope portion 12b are provided on a thread 12 of a multi-pitch screw 10 alternately. The flat portion and the slope portion are provided on the thread of a multi-pitch nut which fastens with this. Consequently, a screw and a nut capable of preventing loosening securely by step are achieved. This enables comfortable and quick feeding and when a torque from a driving source is interrupted, step-like self-lock is activated.
