A lens barrel is capable of selectively establishing a power focus mode in which an internally housed motor moves a taking lens to a position of any desired focal length, a single "auto-focus" mode in which the taking lens is moved to a position which is in focus to a stationary object being photographed, and a sequence "auto-focus" mode in which the taking lens is continuously moved in focus to a moving object being photographed. Any one of these modes is suitably selected by a mode changing switch. A movement of the taking lens in each mode is initiated by an operating member.

An article exchange apparatus which can be used in an auto-loader having an exchange arm, an automatic tool exchange apparatus of a machine tool and the like, comprises an indexing mechanism constructed of a prime mover and a plurality of follower units. The apparatus also includes a mechanism for effecting intermittent indexing operations alternately at the plural follower units in response to a rotational drive of the prime mover. A hydraulic circuit is coupled to the prime mover for imparting such a rotational drive thereto, which is necessary for one cycle of a predetermined operational sequence. The prime mover is coupled to each of the follower units so that, with rotation of the prime mover, one of the units is rotated while the other is held fixed. During one full cycle, each of the follower units executes two indexing motions and has two pause cycles. The apparatus also includes a chuck for gripping an article which is engageable with each of the follower units for rotating the chuck and opening and closing the chuck. A first one of the follower units during the latter half of a first indexing movement thereof, closes the chuck and an arm carring the chuck and also forming part of the apparatus is raised during the first indexing movement of the other follower unit. The arm is rotated by the second indexing movement of the first follower unit. The arm is then lowered by the second indexing term of the other follower unit where upon the chuck is opened during the first half of the first indexing movement of the first follower unit.

A tape-containing cartridge accommodates an endless tape either in the form of random loops or in the form of a tape roll wound on a single reel. A tape passageway extends the cartridge from a cavity adjacent a back wall, thence between a first side wall and a first internal wall past pad means and thence between a front wall and a second internal wall past a transducer-receiving opening formed in the front wall and thence between a pinch roller and portions of the front and second side walls into the cavity. The second side wall has an opening facing the pinch roller for receiving an external capstan. A positional relationship between the pinch roller and the capstan is selected such that a tangential force line at the contact point of the pinch roller and the capstan points inwards of the second side wall. An inward protrusion and a rotatably mounted guide roller provide a limited opening at the entry to the tape passageway to prevent tape creasing at the entry, while limiting drag on the tape.

The present invention aims at providing a plasma processing apparatus for performing a plasma processing on a planar substrate body to be processed, the apparatus being capable of generating the plasma with good uniformity and efficiently using the plasma, and having a high productivity. That is, the plasma processing apparatus according to the present invention includes: a vacuum chamber; one or plural antenna supporters (plasma generator supporters) projecting into the internal space of the vacuum chamber; radio-frequency antennas (plasma generators) attached to each antenna supporter; and a pair of substrate body holders provided across the antenna supporter in the vacuum chamber, for holding a planar substrate body to be processed.

According to one embodiment, an electroforming master comprises a patterns of protrusions and recesses formed on one major surface of an Si substrate having two major surfaces, corresponding to information for positioning of a read/write head (a preamble, address, and burst), recording tracks or recording bits. Impurity ions are doped in the surface of this patterns of protrusions and recesses. The impurity ion concentration distribution in the film thickness direction of the Si substrate has a peak in a portion from the patterns of protrusions and recesses surface to a depth of 40 nm in the film thickness direction. The impurity concentration of this peak is 1×1020 to 2×1021 ions/cm3.

According to one embodiment, a magnetic recording medium includes a substrate, an auxiliary layer formed on the substrate, and at least one perpendicular magnetic recording layer formed on the auxiliary layer. The perpendicular magnetic recording layer includes a magnetic dot pattern. The perpendicular magnetic recording layer is made of an alloy material containing one element selected from iron and cobalt, and one element selected from platinum and palladium. This alloy material has the L10 structure, and is (001)-oriented. The auxiliary layer includes a dot-like first region covered with the magnetic dot pattern, and a second region not covered with the magnetic dot pattern. The first region is made of one metal selected from (100)-oriented nickel and (100)-oriented iron. The second region contains an oxide of the metal used in the first region.

A side surface light emitting unit illuminates, from its side surfaces, one or more objects to be illuminated which are arranged to extend in one direction on a flat surface. The side surface light emitting unit is provided with a light guide body arranged along the side surface of the objects to be illuminated, for projecting light to the side surfaces of the objects, and an LED arranged at least on one end of the light guide body. In the side surface light emitting unit, the upper surface and the lower surface, excluding the side surfaces facing the objects, are blocked from light. The objects to be illuminated, such as key switches, can be brightly illuminated by unintermittent continuous outgoing light, along the arrangement direction of the objects from one end.
