摘要:
A filling and sealing process and apparatus for retort foods, in which a plurality of retort pouches are treated at the same time. The retort pouches are gripped by a plurality of grippers fixedly connected to an endless transfer chain and fed through first, second, third, fourth, fifth, sixth, seventh and eighth stations. The endless transfer chain is arranged to be intermittently movable around the outer periphery of a platform mounted on a base. At the first station, a plurality of retort pouches are gripped by the grippers and opened and dilated at the second station. The opened retort pouches are fed to third station where a defectively opened retort pouch is sensed and released from the gripper. The retort pouches gripped by the grippers are fed to the fourth station, where solid food materials are introduced into the retort pouches. At the fifth station, the retort pouches are supplied with viscous liquid. The retort pouches containing solid materials and viscous liquid are fed to the sixth station, where the remaining air is released from the pouches and the openings of the respective pouches are primarily sealed. At the seventh station, the openings of the respective pouches are secondarily sealed and, at the eighth station, the sealed portions of the pouches are cooled so that the sealed portions are solidified and subsequently released from the grippers. Each step of the process at the respective stations is performed in synchronism with the intermittent movements of the transfer chain so that the plurality of retort pouches are treated at the same time at each step.
摘要:
A method for dividing a data area on a disk into a plurality of concentric zones and determining a format for each zone so that data tracks in the zone have the same number of data sectors. The method includes dividing a data area into a plurality of zones with provisional boundaries. The method also includes determining a linear recording density for a selected zone. The method further includes selecting the number of data sectors per data track corresponding to the determined linear recording density from specified values. Moreover, the method includes resetting a boundary of the zone at a new boundary shifted from the provisional boundary according to a selected value.

Embodiments of the invention prevent offtrack write that will be caused due to a head vibration in a storage device. In one embodiment, a hard disk drive (HDD) judges approval/disapproval of write of user data to a magnetic disk by using a read signal for user data in addition to servo data in write processing. Thus, a head vibration which cannot be precisely detected based on servo data is detected to prevent off-track write. More specifically, the HDD acquires a read back signal amplitude of a read element with respect to a user data sector within adjacent servo data during a write access phase, and detects a vibration from a maximum value MAX and a minimum value MIN of the read back signal amplitude to judge data write approval/disapproval.

Embodiments of the invention provide a magnetic disk drive that does not generate errors when information is read even if considerable time has elapsed after the information was written on the magnetic disk. In one embodiment, a magnetic disk has a storage area divided into a plurality of sectors ST1. Time stamps TP1 corresponding to each sector data m1 stored in the sectors ST1 are stored in a time stamp recording medium. A processor controls the magnetic disk drive to read time stamps TP2 of sector data m2 stored in any sectors ST2 of the sectors ST1 and refresh sector data m3 selected based on an elapsed time calculated from information about the time when the time stamps are read and the time stamps TP2.
摘要:
An RW offset setting method which includes recording a test pattern by a write head, reading the test pattern by a read head, measuring an amplitude of a read back signal at each tracking position, finding an approximate expression of a profile of the measured amplitude, finding a tracking position, and finding a RW offset based on this tracking position, setting a RW offset for all tracks in the disk device based on the RW offsets about the plurality of tracks to be measured. A read data error recovery method that includes the steps of determining an off-track direction where the amplitude increases, searching an off-track position where the amplitude becomes a local maximum, measuring the amplitude at each off-track position reading data recorded in the data sector.
