A method for rewriting data in a three-dimensional optical memory element created in glass with ultrashort light pulse includes creating a bit due to a photo-induced contrast in index of refraction inside the glass in three dimensions depending of the strength of a first ultrashort-pulse laser beam. Then, irradiating the bit created in three dimensions with a second ultrashort-pulse laser beam having a lower energy than the strength of the first ultrashort-pulse laser beam while condensing the second ultrashort-pulse laser beam with an optical lens at a point shifted from the bit to be moved by a predetermined distance in an opposite direction from the direction of propagation of the first and second ultrashort pulse laser beams, thereby moving the bit for rewriting.

A communication system including a master station communication device and multiple slave station communication devices is disclosed. The master station communication device transmits a transmission request simultaneously to the slave station communication devices. The transmission request includes identification information identifying one or more of the slave station communication devices that are authorized to transmit information and time information indicating duration of time for which the one or more of the slave station communication devices are authorized to transmit the information. The one or more of the slave station communication devices transmit the information to the master station communication device based on the transmission request transmitted from the master station communication device.

A magnetic recording/reproducing apparatus for recording information on a disc-like recording medium and/or for reproducing the recorded information therefrom. The magnetic recording/reproducing apparatus has a pair of magnetic head devices each composed of a magnetic head chip and a sliding pad for slidably holding the disc-like recording medium therebetween under a predetermined contact pressure. The magnetic head chip is surrounded at a predetermined interval by the sliding pad and the top portion of the magnetic head chip is disposed so as to protrude by a predetermined amount from a sliding surface of the sliding pad which comes into contact with the said disc-like recording medium. The pair of recording head devices are aligned with each other with the disc-like recording medium being held therebetween so that the magnetic head chips are arrranged at different positions at the same interval with respect to the sliding pads in a radial direction of the disc-like recording medium. When the interval from each of the magnetic head chips to each of the sliding pads is a and the interval between said magnetic head chips is b, the positions of the magnetic head chips with respect to the sliding pads are determined so as to satisfy the following relation,b/2.ltoreq.a.ltoreq.b.

A magnetic record/playback apparatus has a head plate and a control plate which are disposed on a tape deck slidably movable in forward and rearward directions. A head is fixed on the head plate and a changeover mechanism for putting a tape driving system selectively into a cue scanning mode is engaged by motion of the control plate. The head plate is formed with an elongated slot extending in the displacement direction of the plates and the control plate is provided with a pin slidable within the elongated slot. The control plate is engaged by a scanning mode operating rod for displacing the control plate forwardly to put the system into normal play or scanning mode and rearwardly.
摘要:
A lock-releasing mechanism for a magnetic record/playback apparatus wherein one plunger is used for changeover of an auto-reverse mechanism and lock-release of FF- and/or REW-operating rod for an automatic music sensor. The lock-releasing mechanism includes a stopper interlocked with the FF- and/or REW-operating rod so as to restrict the pulling stroke of the plunger when the FF- and/or REW-operating rod is locked.

A tape pack ejecting mechanism wherein a tape pack is loaded and unloaded into and from a pack receiving structure pivotally connected at one end portion thereof to a chassis so as to allow pivotal movement thereof, locking of the pack receiving structure in a tilted position is released by loading of the tape pack, bringing the tape pack into a horizontal playback position, and the pack receiving structure is again tilted through rotation of an engaging member upon depressing of an eject lever to eject the tape pack, which mechanism is characterized by a guide provided at one side portion of the pack receiving structure for guiding the loading and unloading of the tape pack; and eject operating member with a tension spring attached thereto which is slidably provided on the guide; said eject operating member having a hanging portion engageable with a rear end of the tape pack and a projection engageable with a lock portion formed on the engaging member; said tension spring being biased to urge when the tape pack is loaded into a playback mode; said engaging member being reset by the rebounding force of the urged spring to eject the tape pack through the operation of the engaging member rotated upon eject operation by the eject lever.
摘要:
A drug sheet includes a base fabric carrying a therapeutic agent containing an electrolytic drug component and applied to or impregnated into a skin-abutting surface of the base fabric. Small needle members carrying small needle-shaped protrusions are scattered on the skin-abutting surface so that the needle-shaped protrusions protrude from the skin-abutting surface. The needle members include a first group of needle members made of aluminum and provided on a first area of the skin-abutting surface, and a second group of needle members made of silver and provided on a second area of the skin-abutting surface. Due to a difference in standard electrode potential between the first and second groups of needle members, electric current flows between the first and second groups of needle members through skin when the needle-shaped protrusions are stuck in the skin. This improves the absorption rate of the drug component.
