摘要:
A backing-up apparatus, upon receiving an instruction to execute backing up, allocates a storage area to store a snapshot to be produced to each time point indicated by the instruction. When the original data is updated after the time point indicated by the instruction, it is checked that the original data corresponding to the place to which the updating has been executed at a time point immediately before the time point indicated by the instruction is stored in the storage area allocated as the storage area to store the latest snapshot produced for the immediately previous time point. When it has been confirmed that the original data is not stored, the original data immediately before the updating corresponding to the place to which the updating has been executed is stored in only the storage area to store the latest snapshot.

An interdevice communication monitoring unit 62-1 calculates a variable timeout time (T2−T) by subtracting an elapsed time T from a predetermined fixed timeout time T2 for monitoring an intermodule communication to monitor an elapsed time of an intermodule communication. The fixed timeout time T2 is a time shorter than a predetermined interface connection check time T1 for monitoring an interface connection with a channel. When the elapsed time T of the intermodule communication exceeds the variable timeout time (T2−T), the interdevice communication monitoring unit requests a channel to separate the interface connection, and then when an end response is obtained from a control module, requests the channel for an interface reconnection and then transmits an end response.

A storage system prevents a time out error of the host I/O caused by a stagnation of command processing in the storage system for accessing a disk device according to the host I/O request and internal I/O request. In DTC, counters for managing the requests in-process for host I/Os (host read) and internal I/Os (pre-fetch, write back) individually are provided, and the number of processing requests to be issued to a virtual disk (RLU) is limited individually. By assigning priority to the host I/Os, the load balance of the host I/Os and internal I/Os can be controlled. For rebuild/copy back, a dedicated load control mechanism is disposed where the load adjustment between ordinary I/Os and rebuild/copy back is performed.

In the present invention, for each set of blocks [#(0) to #(N-1)] storing update data, a history block [#(N)] storing an update state value, for example, a generation, time or check code, showing an update state is provided, constituting a set of management data as a check object. When writing update data on a disk, a new update state value is calculated for the same set of management data and stored in memory as update state confirmation value. The new update state value is also set as write data in the history block in the same set of management data, and the entire of the set of management data including update data and update state value are written onto a disk. The history block is read and disk write omissions are detected by comparing the update state value and the update state confirmation value stored in memory.

The invention aims at providing a crane equipped with an inspection device that can maintain excellent inspection conditions without decreasing cargo transporting efficiency. On a container transporting route of a quay crane, a truck (position adjustment device), is provided moveably in a direction across this transporting route. An inspection device, which inspects the container, is provided on this truck. An upper part frame, which projects above the inspection device, and a lower part frame, which projects under the inspection device, are provided on the truck. An upside position detector, which detects the relative position of the container and the inspection device in the direction of movement of the truck, is provided in a position higher than that of the inspection device of the upper frame. A control device is provided, which controls operation of the position adjustment device based on detection results of the upside position detector so that the inspection device and the container are positioned appropriately for inspection.

The present invention has been developed to carry out the dual-writing of data in cache memories at a higher speed through a single address designation for the improvement of processing performance. In the present invention, a host interface module produces addressing information for designating two written-in destinations, and a bridge module produces two transferred-to addresses and written-in addresses of the cache memories on the basis of the addressing information so that data to be written is transferred to two management modules corresponding to the two transferred-to addresses to be written at the written-in addresses of the cache memories of the management modules.

In a vibration actuator using a magnetic circuit device (14), a supporting arrangement (23) elastically supports the magnetic circuit device. A coil (17) is inserted into a magnetic gap (15) of the magnetic circuit device and is supported by a vibration plate (19). The vibration actuator has a first operation mode in which the magnetic circuit device mainly vibrates to transmit vibration through the vibration plate to the outside, a second vibration mode in which the coil mainly vibrates to produce a buzzer sound through the vibration plate, and a third vibration mode in which the magnetic circuit device and the coil mainly vibrate to produce a sound corresponding to a speech through the vibration plate.

An optometric apparatus includes a luminous flux projecting unit for projecting a luminous flux to one eye of a subject to be measured, an imaging unit for imaging an anterior part of the eye illuminated by the luminous flux projecting unit, a position detecting unit for detecting the position of the eye in accordance with an image output from the imaging unit, an optometric unit for measuring the eye, a drive unit for driving the optometric unit, and a control unit for controlling the drive unit. The control unit controls the drive unit to align the optometric unit with the eye in accordance with a signal output from the position detecting unit and then controls the drive unit to move the optometric unit to the other eye of the subject when the measurement of the one eye by the optometric unit is completed.

A non-contact tonometer has a fluid projecting device for compressing fluid in a compression chamber and projecting the fluid to the cornea of an eye to be examined located at a predetermined distance therefrom. The fluid injecting device is capable of selecting a first range as a pressurizing range for measurement of intraocular tension and a second range including a value higher in the degree of pressurization relative to the first range. The tonometer also includes a measuring device for detecting a predetermined deformation of the cornea of the eye to be examined caused by the compressed fluid and measuring the value of the intraocular tension of the eye to be examined, a change-over device for changing over the pressurizing range for measurement of intraocular tension between the first range and the second range, a state detecting device for effecting at least one of the detection of the fact that measurement is impossible by the measuring device and the detection of the replacement of the eye to be examined by another eye, and a control device for operating the change-over device on the basis of at least one of the output of the state detecting device and the measured value measured by the measuring device.

A method of mounting a torque converter on a transmission comprises the steps of setting the transmission to have the tubular members extending horizontally, holding the torque converter by holding means which is movable in vertical and horizontal directions, positioning the torque converter to cause an imaginary axis of a turbine runner in the torque converter to coincide with a common imaginary axis of two coaxial tubular members in the transmission, moving the torque converter toward the transmission in the horizontal direction so as to engage an engaging portion of the turbine runner with an end portion of an inner one of two coaxial tubular members of the transmission, positioning further the torque converter to cause an imaginary axis of a stator in the torque converter to coincide with the common imaginary axis of two tubular members; and moving further the torque converter toward the transmission in the horizontal direction so as to engage an engaging portion of the stator with an end portion of an outer one of two tubular members of the transmission.
