摘要:
A peripheral device operating with power supplied from a host device includes a receive unit receiving an external signal and a controller. The controller causes at least one of the functions of the peripheral device to operate intermittently when the host device is in a sleep mode. Further, upon reception of the external signal via the receive unit, the controller forces the host device to shift to an active mode based on the signal received. As at least one of the functions of the peripheral device is forced to operate intermittently when the host device is in the sleep mode, the consumption of the power supplied from the host device is reduced.

A digital optical transmission apparatus includes a modulation portion for modulating data to be transmitted in an ASK modulation method, and an E/O modulation portion for converting an electrical signal output from the modulation portion into an optical signal having a base band component with a constant DC level. DC-biased or FSK-biased may be employed as a method of making constant the DC level of the base band component.

A digital optical transmitter includes a main/subdata modulation part for distorting a main data modulated signal waveform in response to sub-data, and an E/O conversion part for converting a subsequently obtained electrical modulated signal to an optical modulated signal and outputting the optical modulated signal. A digital optical receiver includes an O/E conversion part for receiving the optical modulated signal, converting it to an electrical modulated signal, and outputting the electrical modulated signal. Additionally, the digital optical receiver further includes a main/subdata demodulation part for demodulating the main data from the electrical modulated signal, while detecting whether or not a distortion signal responsive to the subdata is superposed on a subcarrier which forms the electrical modulated signal. If the distortion signal is superposed on a subcarrier, the main/subdata demodulator part demodulates the associated subdata.

It is possible to provide a small intestine endoscope training simulator (11) which allows to obtain a feeling similar to that of inserting an endoscope (38) into the small intestine (34) of the living body (30) and learn the actual operation of the endoscope (38). This training simulator (11) includes a plurality of longitudinal elastic members (32) for applying an elastic force to each of a plurality of portions of a simulated small intestine (13). One end portion sides of the plurality of longitudinal elastic members (32) are respectively attached to the first attachment portions (27) on the simulated small intestine (13) side. The other end portion sides of the plurality of longitudinal elastic members (32) are respectively attached to the second attachment portions (33, 57) on the case (12) side.
摘要:
A method for measuring a variation in the floating amount of a magnetic head comprising: measuring the ambient temperature which is a temperature of the magnetic storage apparatus; reading a signal recorded in the magnetic recording medium; measuring a signal value which is a value related to a signal read in the reading; and calculating a variation in the floating amount of the magnetic head based on relationship information which is information representing a relationship between the ambient temperature and signal value that have previously been measured, measurement value which is the ambient temperature measured in the measuring of the temperature, and signal value measured in the measuring of the signal.

Signals are recorded on and reproduced from a magnetic disk by a head with an azimuth angle which changes depending on a radial position on the magnetic disk. The magnetic disk includes a first recording region having tracks recorded with an azimuth angle less than or equal to a predetermined value, a second recording region having tracks recorded with an azimuth angle greater than the predetermined value, and an overlapping region in which two mutually adjacent tracks overlap in a radial direction of the magnetic disk, where a track pitch of the tracks within the first recording region is different from a track pitch of the tracks within the second recording region.

A disk control section of a disk apparatus comprises an identification section for identifying information regarding a position at which the head positioning servo information is stored, a position calculation unit for calculating the position on a disk medium where recording/reproduction of the record information is to be performed, a comparison and decision unit for comparing the information regarding the position identified by the identification unit with the position information calculated by the position calculation unit each time a predetermined command is received from the higher-level device, and for deciding whether or not the position identified by the identification unit is the position at which the record information is to be recorded on or reproduced, and a skip recording/reproduction unit for carrying out control such that when it is judged, on the basis of the result of the comparison made by the comparison and decision unit, that the position identified by the identification unit is the position at which recording/reproduction of the record information is to be performed, the record information is recorded/reproduced while skipping the position identified by the identification unit. Accordingly, it becomes possible to record and reproduce variable-length data even in a sector-servo type disk apparatus and a hybrid type disk apparatus, so that their storage capacities can be used effectively. In addition, recording and reproduction of data can be performed at high speed.
摘要:
Each one of intermediate control devices and n-number of disk drives are daisy-chain connected by control-information signal lines in each of downward and upward directions. Serial communication means (a driver and a receiver) sends and receives control information in the form of a bit serial between the intermediate control devices and each drive via the control-information signal lines in the downward and upward directions in accordance with a serial interface. This makes it possible to diminish the size of a magnetic disk apparatus by reducing the number of control-information signal lines and the numbers of drivers and receivers, and to cut down on power consumption so as to lower cost.

摘要:
An air conditioning seat device includes an air blower, and a dehumidifier for dehumidifying the air sent from the air blower owing to adsorption, and blows out the dehumidified air to holes provided on a skin of a seat through an air duct. In this makeup, the sweat on the body surface and in the clothes is rapidly vaporized, causing a large amount of vaporization heat loss. Accordingly, the human body feels coolness, and steaminess on the skin is suppressed owing to the sweat vaporization.
