Abstract: A vaporization device (10) for a low-temperature liquefied gas is provided with: a plurality of heat-transfer pipes (20) into which liquefied natural gas (LNG) is introduced; upper headers (24) which cause natural gas (NG) flowing out from the plurality of heat-transfer pipes (20) to converge; first troughs (28) which supply seawater to the plurality of heat-transfer pipes (20) such that the seawater flows down along outer surfaces of the plurality of heat-transfer pipes (20); and second troughs (36) which drop seawater onto the upper headers (24) from above such that the seawater flows down along outer surfaces of the upper headers (24). In the plurality of heat-transfer pipes (20), the LNG is heated by being subjected to heat exchange with the seawater. In the upper headers (24), vapourized NG which has been heated in the plurality of heat-transfer pipes (20) is heated by being subjected to heat exchange with the seawater flowing down along the outer surfaces of the upper headers (24).

Abstract: Disclosed is a device configured to clamp a bar member (2) by inserting the bar member (2) through a through hole formed by bending a chain (1) including inner link plates (4) and outer link plates (3) connected via pins (5) so as to be freely bendable into a saw-tooth shape, fixing an end (A) of the chain 1 and clamping the bar member (2) by the pins (5) in a state of blocking the bar member (2) from being pulled out toward the other free end (B), the bar member (2) can be strongly clamped by forming the pins (5, 5 . . . ) in non-circular shape in cross section.

Abstract: An extendable stick having an outer pipe, an inner pipe, a core bar fixed on the outer pipe, a zigzag chain having a first portion and a second portion, an unlocking pipe, an unlocking member attached to one end of the unlocking pipe, an unlocking pin, and an unlocking finger grip attached to the unlocking pipe through a hole in the inner pipe by means of the unlocking pin, wherein the first portion being fixed to the inner pipe, the core bar running through the zigzag chain. The stick can optionally have a pedal and/or a spring to provide force to stretch the zigzag chain.

Abstract: A broadcast data transmission station for use in a data transmission system. The station includes a traffic amount counter for computing the amount of broadcast data present on a transmission line during a unit time period. A comparator indicates whether the traffic amount computed by the traffic amount counter has reached a predetermined limit. If the limit has not been reached, a transmission execution circuit allows the broadcast data to be sent on the transmission line. If the limit has been reached, a retransmission attempt circuit and delay timer cause the station to wait a delay time and then compare the traffic amount with the limit again. A retransmission attempt counter computes the number of attempts to send the same broadcast data, and a suspension circuit suspends further attempts to send the same broadcast data when the number of attempts counted by the retransmission attempt counter reaches another predetermined limit.
