To provide a catalyst, which is formed from a perovskite oxide, for thermochemical fuel production, and a method of producing fuel using thermochemical fuel production that is capable of allowing a fuel to be produced in a thermochemical manner.Provided is a catalyst for thermochemical fuel production, which is used for producing the fuel from thermal energy by using a two-step thermochemical cycle of a first temperature and a second temperature that is equal to or lower than the first temperature, wherein the catalyst is formed from a perovskite oxide having a compositional formula of AXO3±δ (provided that, 0≦δ≦1). Here, A represents one or more of a rare-earth element (excluding Ce), an alkaline earth metal element, and an alkali metal element, X represents one or more of a transition metal element and a metalloid element, and O represents oxygen.

摘要:
In a method and apparatus for predicting process results of objects being processed in a processing chamber of a processing apparatus, operation data and process result data obtained at the time of processing each of the objects are collected and a multivariate analysis is performed on the basis of the collected operation data and process result data to obtain a first correlation therebetween. Process results are predicted on the basis of the first correlation. Weighting coefficients for the respective operation data are set on the basis of the predicted process results. A second correlation between the weighted operation data and the process result data is obtained by a multivariate analysis. Process results are predicted by using operation data, obtained when objects other than the objects used to obtain the second correlation are processed, on the basis of the second correlation.

A cam mechanism of a lens barrel includes first and second ring members; cam grooves having similar cam diagrams formed on one of the first and second ring members, and cam followers formed on the other thereof. Two groove/follower groups positioned at different positions in a circumferential direction. The cam grooves of one of the two groove/follower groups intersect cam grooves of another of the two groove/follower groups, respectively. One of the following is satisfied: (a) a distance in the optical-axis direction between front and rear groove/follower sets of one of the two groove/follower groups is different from that between the front and rear groove/follower sets of another of the two groove/follower groups, and (b) a distance in the circumferential direction between two front groove/follower sets of the two groove/follower groups is different from that between two the rear groove/follower sets of the two groove/follower groups.

A retracting mechanism of a zoom lens barrel includes first, second and third lens groups, wherein the first and third lens groups are integrally moved along an optical axis during variation of a focal length, and wherein at least one of the first and third lens groups is moved relative to the other to reduce a distance therebetween when the zoom lens barrel is fully retracted. The retracting mechanism includes first, second and third lens group moving rings; a cam mechanism for independently moving the first and second lens group moving rings; a second lens group support frame; an intermediate member fixed to the second lens group support frame; and a biasing device for biasing the third lens group moving ring away from the first lens group moving ring. The biasing device functions between the intermediate member and the third lens group moving ring.

A retracting mechanism of a zoom lens barrel includes a first through third lens group moving rings; a first linear guide projection formed on the first lens group moving ring to be engaged in a linear guide slot from outside the second lens group moving ring, the first linear guide projection including a hanging groove formed therealong, a rear end of the hanging groove being closed; a second linear guide projection formed on the third lens group moving ring to be engaged in the linear guide slot from inside the second lens group moving ring; and a linear moving key projecting from a front end of the second linear guide projection to be engaged in the hanging groove. A rear moving limit of the third lens group moving ring is determined by contact of the linear moving key with the closed end of the hanging groove.

A lens barrel includes first and second lens groups guided in an optical axis direction without rotating about the optical axis, first and second support frames which support the first and second lens groups and include first and second cam followers, respectively; and a cam ring which is rotatable about the optical axis and includes a cam groove. The cam groove is formed as a continuous groove and includes first and second groove portions via which the first and second cam followers are guided to move the first and second lens groups, respectively. One of the first cam follower and the second cam follower enters one of the first groove portion and the second groove portion after passing through the other of the first groove portion and the second groove portion in a preparation stage of the lens barrel.

A lens barrel includes a movable lens frame and a cam ring for moving the movable lens frame in a direction of an optical axis via a movement of the cam ring which is rotatable about the optical axis and movable in the direction thereof. The lens barrel includes a stationary ring provided around, and coaxial with, the cam ring; a rotatable ring provided around, and coaxial with, the stationary barrel, the rotatable ring being driven to rotate about the optical axis. A cam follower extends radially outwards from the cam ring, and a cam through-slot and a rotation transfer groove which are formed on the stationary ring and the rotatable ring, respectively, so that the cam follower is engaged in the cam through-slot and corresponding rotation transfer groove. The cam through-slot includes a linear and an inclined slot portion.
摘要:
Lens barrel has a lens supporting frame to which a frontmost lens group is fixed, a first moving frame to which the lens supporting frame is engaged, a second moving frame to which a rear lens group which is positioned behind the frontmost lens group is supported, and a support frame movement mechanism for moving the first and second moving frame between ready-to-photograph positions and accommodation positions behind the ready-to-photograph positions in an optical axis direction. The support frame movement mechanism makes the first moving frame and the second moving frame rotate about the optical axis relative to each other with the lens supporting frame and the second moving frame being in contact with each other when the first moving frame and the second moving frame are positioned in the vicinity of accommodation positions. One of the lens supporting frames includes a low-frictional portion provided on a contacting surface thereof.
