    摘要： A lens unit includes a lens barrel having an imaging optical system arranged therein and a movable unit having a movable lens, the movable unit being movable in an optical axis direction with respect to the lens barrel. The lens barrel includes a first member and a second member adapted to be coupled together in a coupling direction. Fixing pieces are provided on the first member and the second member, respectively, and fixing means is filled between the fixing pieces when the first member and the second member are coupled together. The respective fixing pieces are provided in positions at which a force is applied in a direction in which the fixing means is compressed by the respective fixing pieces when a force is applied to the first member and the second member in a direction in which the first member is released from the second member.

    摘要： Disclosed is a method for production of lower olefins from a raw material containing dimethyl ether (DME), which can produce lower olefins (e.g. propylene) with good yield and in an economically advantageous manner by prolonging the time until the reversible deactivation of a zeolite catalyst and preventing the irreversible deactivation of the catalyst, can reduce the amount of water to be recycled to increase the thermal efficiency of the process, and can simplify the facilities and operations. Also disclosed is a method for improving the yield of propylene with good efficiency under practical operating conditions. A feed gas which comprises a DME-containing feedstock gas and an additive gas and further contains steam at a specific proportion is introduced into an olefin synthesis reactor to contact the feed gas with a zeolite catalyst, thereby producing a hydrocarbon product containing C2-C5 olefins. Propylene or the like is separated/collected from the hydrocarbon product, and at least a part of the remainder is used as at least a part of the additive gas.
