The present invention provides a nucleic acid conjugate in which a sugar chain ligand is bonded to an oligonucleotide via a linker, the sugar chain ligand having O-bonded mannose at its non-reducing end.

Nucleic acid conjugate

The present invention relates to a nucleic acid conjugate represented by the following formula 1: wherein X is an oligonucleotide, L1 and L2 are each independently sugar ligand, and S1, S2 and S3 are each independently a linker.

An optical disk apparatus in which a head is accommodated in a movable part which moves the head along a guide shaft in a radial direction of an optical disk. The guide shaft is engageable with the movable part and extends in the radial direction of the optical disk. The optical disk apparatus has a guide shaft compression mechanism which applies a compression force toward the movable part, which force is distributed, approximately uniformly, along the radial direction of the optical disk, to the guide shaft so that the movable part can be properly engaged with the guide shaft so as to move smoothly and stably along the guide shaft in the radial direction of the optical disk.

Disk recording and reproducing apparatus having a guide shaft

A disk storage device includes a head part which writes data into a storage disk loaded into the disk storage device and reads data from the storage disk, a linear actuator moving the head part in radial directions of the storage disk, an eject member which is operated when the storage disk is ejected, and a movement mechanism which moves the storage disk to an eject portion in response to an operation of the eject member and which moves the storage disk to a read/write position. A lock part, which has a lock member cooperating with the movement mechanism, keeps, in response to the operation of the eject member, the head part stationary at the eject position by the lock member which engages with one of the head part and the linear actuator.

Disk storage device having a carriage locking mechanism

Magnetic optical disk drive

Magnetic optical disc drive

A magneto-optical disk storage has an erroneous insertion preventing mechanism which projects into a holder so that it can touch the magneto-optical disk cartridge in order to prevent the same from being inserted. The erroneous insertion preventing mechanism mechanically engages with the magneto-optical disk cartridge and moves in a direction approximately vertical to the recording suface of the magneto-optical disk to allow the magneto-optical disk cartridge to be inserted only if the magneto-optical disk cartridge is being inserted into the holder with a correct orientation.

Magneto-optical disk storage having erroneous insertion prevention

A magneto-optic disk unit includes a cartridge holder having an insertion opening, an inside surface and first and second surfaces, an erroneous insertion preventing mechanism having at one end a stopper portion for prohibiting erroneous insertion of a magnetic disk cartridge and at the other end an insertion detecting portion for detecting insertion of a magnetic-optic disk cartridge, and a supporting mechanism for rotatably supporting the erroneous insertion preventing mechanism. The insertion detecting portion projects inside of the cartridge holder from an upper surface of the cartridge holder, so that when the magneto-optic disk cartridge is inserted the insertion detecting portion moves outside of the cartridge holder to allow insertion of the magneto-optic disk cartridge, and that when the magnetic disk cartridge is inserted the insertion detecting portion does not substantially move, thus permitting the stopper portion to prevent insertion of the magnetic disk cartridge.

Magneto-optic disk unit having means for preventing erroneous insertion

A magneto-optic disk unit comprises a casing having an opening through which a disk cartridge is inserted into and extracted from the casing, a cartridge holder having an inserting opening for receiving the disk cartridge which is inserted through the opening of the casing, and an erroneous insertion preventing mechanism which is provided on the cartridge holder. The erroneous insertion preventing mechanism comprises an erroneous insertion preventing part which is provided in an inserting path of the disk cartridge and confronts a sloping surface of a magneto-optic disk cartridge which is inserted through the opening of the casing in a correct position for permitting the insertion of only the magneto-optic disk cartridge to a predetermined position within the cartridge holder when the magneto-optic disk cartridge is inserted in the correct position.

A mechanism for actuating a shutter of a cartridge accommodating an optical disk so as to expose a window defined in the cartridge responsive to an insertion of the cartridge into the apparatus and so as to cover the window responsive to the withdrawal of the cartridge from the apparatus. The mechanism comprises a base provided in a body of the information recording/reproducing apparatus. The base comprises a top plate defining a space for accepting the cartridge when the cartridge is inserted into the apparatus. An arm is held in said space so as to rotate freely relative to the base in a plane generally parallel to said top plate. The arm carries a projection adapted to engage with a corresponding depression formed on a front face of the shutter located at a front side of the cartridge which enters first into the space when the cartridge is inserted. A coiled spring urges the arm in a first direction opposing the rotation of the arm when the cartridge is inserted into said space. The spring further urges the arm in a second direction towards the top plate such that the arm maintains contact with an inner surface of said top plate which faces the space.

Mechanism for actuating a protective shutter provided on a cartridge

A clamping mechanism for clamping a carriage of an information recording/reproducing apparatus recording and/or reproducing an information signal on and from a disk-shaped rotary recording medium accommodated in a cartridge comprises a clamping device provided movably on the body of the recording/reproducing apparatus between a clamped state in which the clamping device is engaged with the carriage so that the cartridge is fixed to the clamping device and a released state in which the clamping member is disengaged from the carriage so that the cartridge is free to move relative to the clamping device, and an actuation device provided movably on the body of the recording/reproducing apparatus between a first state and a second state such that the actuation device urges the clamping device to the clamped state when the actuation device is in the first state and the actuation device urges the clamping device to the released state when the actuation device is in the second state.

A recording head of a magneto-optical disk apparatus for recording and/or erasing an information signal on and from a magneto-optical disk mounted on the apparatus comprises optical pickup device disposed at a first side of the magneto-optical disk for producing an optical beam such that the optical beam is focused on the first side of the magneto-optical disk, pickup feeding mechanism provided on a frame of the magneto-optical disk apparatus for moving the optical pickup device along a path extending in a radial direction of the disk, a stepping motor disposed at a second side of the magneto-optical disk, the stepping motor having a housing containing a rotor magnet and a stator winding surrounding the rotor magnet, the rotor magnet including a plurality of elongated magnetic parts magnetized to either one of the N-pole and S-pole and arranged with alternate polarity about a rotary axis of the stepping motor such that each of the elongated magnetic parts extends parallel to the rotary axis, the rotor magnet further extending beyond the housing of the stepping motor, and mounting mechanism for mounting the stepping motor on the frame of the apparatus such that the rotor magnet projecting beyond the housing of the stepping motor extends substantially parallel to the disk along the path of the optical pickup device.
