摘要:
A transmit packet generated by a CPU 1 is held in a buffer 100a (100b). From among packets received from Ethernet 820a (820b), a packet, a destination of which is a communication device 800, is held in the buffer 100a (100b). A packet which should be transmitted is transmitted from a transfer judging circuit 200 to Ethernet 820a or 820b through a MAC unit 300a or 300b. If a transfer judging circuit 200 judges a packet from the Ethernet 820a to be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet 820b through MAC 300b. If a usage rate of a transferring FIFO buffer 130a (130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer 120a (130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet 820a or 820b in preference to the transmit packet. This prevents a transfer buffer means from overflowing.

A tactile device of a tactile display slides above an object. The tactile device comprises three rods which are free to move up and down. Lower ends of the rods are in contact with a surface of the object. Upper ends of respective rods touch a palmar-side skin equivalent to positions of three joints of a first finger or a second finger. When the tactile device is slid, upper ends of respective rods move up and down in accordance with a surface relief of the object. In response to the movement of the tactile device, the three rods push three finger joint positions of the palmar-side skin with a stroke equal to a height of the relief.

The purpose of the present invention is to provide a shearing force reinforced structure of an existing RC structure body that can simply and surely ensure a predetermined pulling-out rigidity. Then a shearing force reinforced structure (1) of the invention is configured with: a side wall (W) of an existing reinforced concrete structure; shearing force reinforced members (20) arranged inside reinforced member insertion holes (10) with bottoms formed in a direction intersecting a major reinforcing bar of the side wall (W); and fillers (30) filled in the holes (10), wherein each of the shearing force reinforced members (20) is configured with a shearing force reinforcing bar (21), a plate head 23 and a ring head (22) respectively fixed at a base end and top end of the reinforcing bar (21); each of the holes (10) is formed at a general part (12) having an inner diameter larger than a reinforcing bar diameter of the reinforcing bar (21) and smaller than a width of the head (23), and a base end width broadening part (11) formed at a base end of the hole 10 and having a diameter larger than the width of the head (23). In accordance with such a shearing force reinforced structure and a shearing force reinforced member, it is enabled to simply and surely ensure a predetermined pulling-out rigidity.

There is provided a sample warper with an idle running preventing mechanism of a yarn guide, wherein yarns are automatically exchanged and successively wound on the warper drum according to a preset yarn order by passing the yarns between the yarn guides and the yarn selection guides, and wherein, when a first yarn being wound on the warper drum by a first yarn guide is exchanged to a second yarn, after a yarn removing operation for removing the first yarn from the first yarn guide is finished, a yarn feeding operation for feeding the second yarn to a second yarn guide is performed while the empty first yarn guide makes one rotation. The sample warper can achieve such an advantage that an idle running time of a yarn guide when exchanging yarns can be reduced considerably and a speed of yarn exchanging is improved remarkably.

A yarn return unit is attached to the distal end portion of the spindle shaft through a front holder. The guide arm is attached to the front holder. The guide plate is positioned in front of the yarn return unit. When the spindle shaft is rotated, a plurality of yarns wound around the plurality of bobbins can be rotated and simultaneously supplied through the yarn return unit and the guide plate.

Provided are a sample warper and a warping method where data regarding yarn diameters of counts are preliminarily input and stored, counts of warping yarns as well as pattern data for warping are input, a conveyor belt feed pitch per revolution of a yarn introduction means is calculated with a warping width, the number of warping yarns, and a warping length (the number of warping windings), and the conveyor belt feed pitch per revolution of the yarn introduction means is controlled according to the counts (yarn thicknesses or yarn diameters). Accordingly, a surface of the yarns wound on a warper drum is finished in a flat state without undulation irrespective of the counts, thereby solving troubles in the next weaving step.
