Abstract: Genetically modified mammalian cells comprising a Tol2 transposon transferred into a chromosome can be obtained by co-transfecting mammalian cells with a Tol2 transposase encoded by a Tol2 transposon found in medaka fish, and a Tol2 transposon lacking this transposase.

Abstract: An objective of the present invention is reading out information correctly from a defective area when a recording medium having a plurality of defective management areas is used. If information is read out correctly from two or more defective recording areas of the recording medium, that information is used.

Abstract: In the circular ring forming the retainer, there is formed a groove for connecting together one end surface of the circular ring (grease placement surface for grease) and a pocket surface. The width of the groove is set such that, on the circumferential direction of the circular ring, it becomes continuously narrower from the far side of the pocket surface toward the near side thereof and, on the depth direction from the placement surface (in the axial direction of the circular ring), it becomes continuously narrower as the depth of the groove increases. In the pawl portion of a pocket, there is formed a cut portion which is continuous with the groove. Along the outer periphery of the circular ring, there is formed a wall portion which projects out from the end surface.

Abstract: A vibration generator comprises a first vibrator having a permanent magnet and supported by a first spring body on a fixing member, and a second vibrator having a coil so disposed as to intersect the magnetic flux of the permanent magnet and supported by a second spring body on the fixing member. One of the first vibration system and the second vibration system serves as a sound source for producing sound waves of audio-frequency for propagation to the outside, and the other vibration system serves as a vibration source for transmitting vibration to the fixing member and vibrating a device.

Abstract: A disk recording device has inside a cabinet a mechanical deck comprising an inner holder for horizontally holding therein a cartridge containing a disk, a chassis movable toward and away from the inner holder and provided with a pickup for projecting a beam on the disk, and an outer holder provided over the inner holder and slidable along the direction of insertion of the cartridge. The inner holder is fixed to the cabinet through holes and cutouts formed in the chassis, and the chassis is movable upward and downward relative to the inner holder. A space for accommodating the pickup is. formed between the lower surface of the chassis and the bottom surface of the cabinet when the chassis is in a completely lowered position.

Abstract: A time lapse VTR carrying out field extraction recording includes a gate for extracting intermittently a supplied video signal at a ratio of one field to every three fields, a switching circuit for designating selectively a tape running speed of either 1/9 or 1/12 the tape running speed of a SP mode in the VHS system, and a servo control circuit for driving a capstan motor to run a magnetic tape at the designated tape running speed. The video signal extracted intermittently by the gate circuit is recorded at an azimuth angle differing from each field by a plurality of video heads on a magnetic head running at the designated tape running speed. As a result, the reproduction compatibility of a magnetic tape having field extraction recorded by a time lapse VTR with an EP mode of a conventional VTR of the VHS system is ensured.

Abstract: A disc player having a tray drive mechanism, a disc clamp mechanism and a pickup assembly which are mounted on a fixed chassis. A spindle motor for drivingly rotating a turntable is coupled to a motor lift mechanism and drivable upward and downward relative to the chassis. The turntable is movable upward from a standby position below a tray in a loading completed position to a disc clamping completed position where the disc can be pressed into contact with a clamp of the disc clamp mechanism. A drive gear mechanism has a plurality of output portions coupled to the tray drive mechanism, the motor lift mechanism, and the pick-up assembly. The drive gear mechanism also has a power transmission change-over device for transmitting the power of a loading motor selectively to are of the clamps mechanism, the tray drive mechanism, and the pick-up assembly.

Abstract: This specification discloses a carriage apparatus including a carriage movable relative to a fixed base bed and driven by a feed screw or the like. Means for well guiding the movement of the carriage is provided between the base bed and the carriage. A ball nut threadably fitted on the feed screw for driving the carriage is coupled to the carriage through a housing, and means for absorbing displacement of the ball nut is provided between the two. Further, to prevent chiefly the rotation of the ball nut, a bellows having high rigidity for torsion and low rigidity for the other forces is provided between the ball nut and the carriage.
