摘要： The radius range of a formatted zone in each medium differs. A floppy disk and an another-standard high-capacity medium are distinguished by reading a reproduction output at an inside position in the formatted zone by heads. Since the another-standard high-capacity medium has a formatted zone starting from a more inside position than that for the floppy disk, both media can be distinguished by reading a reproduction output by the heads to check a difference in the inside position of the formatted zone.

摘要： A vibration generator system is capable of generating vibrations of a frequency that can be bodily sensed by humans, notwithstanding a small size, and making setting of a configuration of vibrations easy. When a drive signal composed of a set of an accumulation signal and a damping signal is given as a natural frequency of a movable body, a vibrational waveform of the movable body makes an envelope. Since a frequency of the envelope is in a lower frequency band than the natural frequency of the movable body, humans can surely sense vibrations. When the number of and a current quantity of excitation signals and reverse excitation signals included in the accumulation signal are changed and the number of and a current quantity of inhibition signals and reverse inhibition signals included in the damping signal are changed, the envelope can be changed in frequency and amplitude, so that it becomes possible to generate a variety of vibrations.

摘要： In a seek operation, in which a head is moved to a target track, the detection output of a head-position detection unit is integrated in each track. Each integrated value is a positive or negative value proportional to an offset given to a center value obtained from the maximal value and the minimal value of the detection output. The center value is compensated for by a compensation value obtained by multiplying the integrated value by a coefficient. As a result, the offset is reduced and a highly precise positional detection is allowed.

摘要： After data recording or reproduction is finished, servo control is stopped within a predetermined time to disable a positional compensation output to a head. While servo control is being stopped, servo data recorded in a medium is monitored. When the head is moved on the medium further than a predetermined distance, servo control is activated to start a positional compensation output to the head. The stop/start of the servo control is implemented by software embedded in the CPU of a disk apparatus.

摘要： A track-follow control device uses a positional error signal representing the positional error between a target track on a recording medium and a head for recording information to or reproducing information from the recording medium. The track-follow control device controls an actuator to follow the target track by means of a signal from a sub-controller for outputting a correction signal by using its gain circuit for performing gain correction in accordance with an output result from a main-controller for outputting a positioning control signal to the actuator and a band-pass filter for allowing the passage of a predetermined frequency of the positional error signal. The sub-controller extracts only an eccentric frequency, which prevents the correction signal from breaking.

摘要： An input device performs various input operations in a secure manner on the same operation plane. A sheet-like display member formed of an organic electroluminescence selectively displays a keyboard input display pattern, a specific operation plane display pattern, and a pad input section display pattern. Additionally, a partial pressing member is configured to press operation areas of the display patterns from downside so that the operations areas are partially deformed in a protruding manner. As a result, the protruding operation areas are clearly sensed by means of sight and touch. Furthermore, a contact position of a finger is detected by an electrostatic capacitance type sheet-like detection member laminated on the sheet-like display member.

摘要： A catheter with a balloon for mitral valve formative operation includes a double tube having an inner tube and an outer tube disposed concentrically. A balloon is fastened at one end to the inner tube and at the other end to the outer tube. A balloon-extending pipe stopper is disposed at the tip of the inner tube and includes an entry diameter at one end sized to receive a balloon-extending pipe with an allowance. An inner diameter of the balloon-extending pipe stopper at an opposite end is smaller than the entry diameter. The inner diameter of the extending pipe stopper is substantially equivalent to a diameter of the balloon-extending pipe. In use, the balloon-extending pipe is inserted into the inner tube and brought into contact with the balloon-extending pipe stopper for axially extending the balloon for contraction in diameter.

摘要： A zone where a head is positioned is determined in a track to be one of zones 1 to 4 according to a combination of the polarities of phase-A and phase-B detection outputs having different phases, and the positional deviation of the head from the current position to the center of the target track is obtained from the phase-B detection output in the zone. The phase-B detection output is provided with a dead zone corresponding to a range where both detection outputs have a phase-difference error. Therefore, even if the phase difference has an error, the positional deviation of the head is accurately calculated.

摘要： A tactile-stimulus generation apparatus is enabled to apply an electric stimulus to a fingertip of a user, and a tactile-stimulus generation sheet configured by arranging a tactile-sensation generation electrode group on an insulating layer is installed on a front surface of a capacitive type coordinate input device. The tactile-sensation generation electrode group is distributed at positions where tactile-sensation generation electrodes overlap first or second electrodes of the coordinate input device as seen in plan view. If the fingertip is in proximity with the insulating layer, the fingertip is capacitively coupled to positive and negative electrodes of the tactile sensation generation electrode group to which a differential voltage is applied, and thus, a portion of a current directing from the positive electrode to the negative electrode passes through the fingertip, so that an electric stimulus is applied to the user due to the current.
