摘要:
A process for steam reforming of hydrocarbons which comprises subjecting a hydrocarbon to steam reforming after desulfurizing the hydrocarbon to a sulfur content of 5 ppb or less. According to the process, a poisoning of steam reforming catalyst by sulfur can be prevented, and stable and economical operation can be attained for a long period.

The present invention provides (1) a process for producing a desulfurization agent which comprises subjecting to hydrogen reduction a copper oxide-zinc oxide mixture prepared by co-precipitation process using a copper compound and a zinc compound; and (2) a process for producing a high temperature-resistant, high grade desulfurization agent which comprises subjecting to hydrogen reduction a copper oxide-zinc oxide-aluminum oxide mixture prepared by a co-precipitation process using a copper compound, a zinc compound and an aluminum compound.
摘要:
A method for the desulfurization of hydrocarbons by desulfurizing unsaturated hydrocarbons or hydrocarbon materials containing unsaturated hydrocarbons, in the presence or absence of hydrogen, using a copper-zinc desulfurizing agent prepared by the co-precipitation method. By this method, the sulfur content of the hydrocarbons can be reduced while suppressing hydrogenation of the unsaturated hydrocarbons.

In a case where, although a radio base station (eNB 1-1) has established an SRS transmission frequency band, a serving radio terminal (UE 2-1) has transmitted, to the radio base station (eNB 1-1), an SRS by use of only a frequency band that is a part of the SRS transmission frequency band, the radio base station (eNB 1-1) allocates a downstream resource block the frequency band of which is included in the SRS transmission frequency band and further the frequency band of which is identical with the frequency band of the SRS received at the latest; then establishes, for the downstream resource block, a transmission weight based on the SRS received at the latest; and then uses the downstream resource block to transmit a radio signal.

Disclosed is a wireless base station (eNB1-1) that sets to each serving wireless terminal (UE2) different frequency bandwidths (SRS transmission frequency bandwidths) that are used when said serving wireless terminals (UE2) send SRS at a predetermined special sub-frame timing. In addition the wireless base station (eNB1-1) sends the set SRS transmission frequency bandwidth information to the serving wireless terminals (UE2).

A device includes a ceramic thin plate member including a fired ceramic sheet; and a metal thin plate member having an outer shape larger than that of the ceramic thin plate member. An outer circumferential portion of the ceramic thin plate member is joined to the metal thin plate member. The ceramic thin plate member has through holes and a plurality of crease portions. Each crease portion has a ridge portion whose crest continuously extends from a joint portion between the ceramic thin plate member and the metal thin plate member toward an outer circumferential portion of the metal thin plate member. Since thermal stress due to a difference in thermal expansion between the metal thin plate member and the ceramic thin plate member can be relaxed through expansion of the crease portions, the ceramic thin plate member does not deform.

A base station allocates at least one of a plurality of wireless channels included in a used frequency hand to a mobile station. The base station includes: a used frequency hand determination unit for determining at least a part of a predetermined frequency band as the used frequency band; a message generation unit for generating a control message including used frequency band information which is placed in a predetermined position and which indicates the determined used frequency hand, and channel allocation information which has a size corresponding to a bandwidth of the used frequency band and which indicates the wireless channel to be allocated to the mobile station; and a modem and a wireless communication unit for transmitting the generated control message to the mobile station.
摘要:
An eNB1-1 transmits an RRC Connection Reconfiguration message to UE2-1 to UE2-3, in which SRS parameters and an application timing parameter are set, the SRS parameters differ for each of the UE2-1 to the UE2-3 and the application timing parameter is common in the UE2-1 to the UE2-3. The UE2-1 to the UE2-3 receive the RRC Connection Reconfiguration message and recognize the SRS parameters and the application timing parameter set in the message. Furthermore, when an application timing of the SRS parameter arrives, the UE2-1 to the UE2-3 apply the SRS parameter to the SRS and transmit the SRS.
摘要:
A transmission path state estimation unit estimates a state of a transmission path to a wireless terminal based on a DRS (Demodulation Reference Signal) included in uplink user data received from the wireless terminal when a re-sending request is received after transmission of an SRS is stopped. A transmission unit forms directivity of a plurality of antennas based on the estimated state of the transmission path and transmits downlink user data.
摘要:
There is provided bonding material having a Young's Modulus after hardening of not less than 20% of articles to be bonded, and an average linear coefficient of thermal expansion after hardening of not more than 70% of the articles to be bonded. This bonding material can suppress deformation of a honeycomb segment due to thermal stress to be generated by a bonding material layer and can suitably be used at the time of manufacturing exhaust gas trapping filters capable of reducing the generation of defects such as a crack, and above all, a diesel particulate filter (DPF) for trapping particulate matter (particulates) in exhaust gas from the diesel engine.
