摘要:
An ozonized oxygen fed from an ozonizer is passed to a reaction tower to treat an object material. In recovering non-reacted oxygen from the reaction tower to reuse in the ozonizer, zeolite is used as an adsorbent to remove impurities contained in the recovered oxygen, such as water, volatile organic materials and CO.sub.2 gas so that a raw material oxygen without containing any impurity is fed to the ozonizer to increase the ozonizing efficiency.

It is an object to effectively enhance rigidity of a subframe installed to couple a pair of right and left wheel suspension members, with a simple structure, and allow a stabilizer to be adequately installed. A subframe (3) installed to couple a pair of right and left wheel suspension members (2) together comprises a cross member (31) provided with a lateral-link support portion (14, 18) supporting an end of the lateral link (5, 6), a pair of right and left side members (33) each extending from a respective one of opposite vehicle-widthwise outer ends of the cross member (31), in a vehicle longitudinal direction; and a pair of right and left reinforcing members (35) each reinforcing a coupling section between the lateral-link support portion (14, 18) of the cross member (31) or a vicinity thereof, and a respective one of the side members (33). A stabilizer (10) is installed above the cross member (31) to extend in a vehicle widthwise direction in such a manner as to couple the right and left wheel suspension members 2, and each of the reinforcing members (35) is provided with a stabilizer support section torsionably supporting the stabilizer (10).

Provided is a wireless relay system that improves system throughput between terminal stations and flexibly makes system throughput variable with respect to short-term traffic fluctuations. In the wireless relay system, a plurality of relay stations relay communication between two terminal stations that perform random access. The terminal stations and the relay stations include a slot synchronization unit, a time synchronization unit, and a transmission unit. The slot synchronization unit synchronizes slot timing of a time slot indicating a unit time. The time synchronization unit performs time synchronization for synchronization of the slot timing. The transmission unit transmits a transmission packet to a wireless line in synchronization with the slot timing. A transmission right is allocated for at least one time slot to each of a plurality of groups which are configured so that a group of a terminal station or a relay station and a group of an adjacent terminal station or an adjacent relay station are different from each other. The transmission unit transmits the transmission packet to the wireless line only in a time slot in which the transmission right is allocated to the group to which the terminal station or the relay station belongs.

Even a site having a complicated curved surface shape, such as a welded spot on a bottom of a nuclear reactor core, is simply and electrolytically etched without discharging an etching liquid in a large amount, whereby grain boundary on the surface of the nuclear reactor core internals can be confirmed visually.When the surface of nuclear reactor core internals is electrolytically etched, a sponge provided with holes having a communicating structure is integrated with an etching liquid, and the etching liquid is gelled, while the integrated combination is disposed in front of an electrode, followed by the application of voltage to turn on electricity at a state in which said electrode is electrically connected to the cathode of a direct-current power supply, and brought into contact with or approximated to the surface of the core internals electrically connected to the anode of the direct-current power supply.

In a method of bonding a first bump on a surface of a first member and a second bump on a surface of a second member, a tip portion of the first bump is provided with a projection having a hardness greater than a hardness of each of the first and second bumps. The first and second members are positioned with respect to each other such that the first and second bumps face each other. The tip portion of the first bump is brought into contact with a tip portion of the second bump by sticking the projection into the tip portion of the second bump.
