摘要:
A lock mechanism for locking a head plate and fast-forwarding and rewinding levers of a tape player comprises step-shaped engage portions formed along side margins of the fast-forwarding and rewinding levers near their one end, a lever lock member pivotally mounted near these ends of the levers for releasable locking engagement with the step-shaped engage portions, and a compression portion formed along a margin of the head plate which unlocks the locking engagement between the lever lock member and step-shaped engage portion when the head plate withdraws concurrently with deenergization of a plunger upon detection of a non-signal portion between pieces of music on a tape.

An intermittent gear wheel lock mechanism includes major engaging portions and secondary engaging portions formed on one surface of an intermittent gear wheel and spaced by a predetermined distance. When an unlock lever is inserted, and a lock member is detached from the major engaging portion, the lock member is moved to the movement path of the secondary engaging portion while the unlock member remains in the inserted position, so that the lock member engages the secondary engaging portion which reaches there as the intermittent gear wheel rotates, and locks the intermittent gear wheel unrotatable. When the unlock lever returns to its original position, the lock member moves from the secondary engaging portion to the movement path of the major engaging portion and engages same to lock the intermittent gear wheel unrotatable.

An auto-reverse mechanism intended for use in a magnetic recording/reproducing apparatus, comprising a means of changing driving force to reel base, means of detecting stopped rotation of said reel base, means of rotating, in response to the operation of said detection means, a power gear provided with intermittent gear section, means of actuating the driving-force changing means and a change plate under the effect of the rotation of said power gear, claw formed integrally with said change plate and having the effect of a spring, and a control hole in which the claw is fitted, the reaction force developed at said claw when the change plate is actuated being utilized as attractive force to the intermittent gear section for making the power gear engage with the other gears.
摘要:
Disclosed is a near-infrared fluorescent imaging agent comprising an indocyanine-based fluorescent dye and a liposome. The near-infrared fluorescent imaging agent of the present invention demonstrates high fluorescence intensity and a long anchoring time in sentinel lymph nodes, thereby making it useful for detecting sentinel lymph nodes in sentinel lymph node navigation surgery. Also disclosed is an indocyanine green derivative that is particularly suitable for use in the near-infrared fluorescent imaging agent of the present invention.
摘要:
A through portion is formed on a semiconductor substrate. Into the semiconductor substrate, a first ion implantation is performed via the through portion. The through portion is at least partially removed in the thickness direction from a region of at least a portion of the through portion when viewed in a plan view. A second ion implantation is performed into the semiconductor substrate at the region of at least the portion thereof. An implantation energy for the first ion implantation is equal to an implantation energy for the second ion implantation.
摘要:
A liquid ejecting head according to the present invention comprises a passage unit and an actuator unit. The passage unit includes a first opening and a plurality of second openings. One end of a dummy passage extends from and is connected to one or more third openings formed within a fix area of the actuator unit on a surface of a first plate, and an other end of the dummy passage is connected to one or more fourth openings formed on a surface of any of plates, via a space formed in a plate other than the first plate. The dummy passage is opened to the atmosphere through the one or more fourth openings.
