Abstract: Medical gauze includes a warp knitted fabric having a warp and weft direction and composed of loops continued in the warp direction. The warp knitted fabric is made of 100% long fiber containing 70% by weight or more of regenerated cellulose-based long fiber. The warp knitted fabric is preferably configured in a marquisette construction. The regenerated cellulose-based long fiber is preferably cuprammonium rayon. Preferably having a width of equal to or greater than 5 mm and equal to or less than 600 mm, and a weight of equal to or greater than 28 g and equal to or less than 290 g per square meter. As the warp knitted fabric is composed of the loops continued in the warp direction and made of 100% long fiber containing 70% by weight or more of the regenerated cellulose-based long fiber, the occurrence of lint can be reduced to improve lint-free performance.

Abstract: A storage apparatus according to an aspect of the present invention is configured to perform a deduplication process on write data from a host. For the deduplication process, the storage apparatus calculates a feature value of write data, and records, in a management region, metadata that is a set of the feature value of the write data and information on a storage position of the write data. However, to prevent the amount of metadata stored in the management region from increasing, if write data meets a predetermined condition, the storage apparatus does not perform the deduplication process, and suppresses creation of metadata of the write data.

Abstract: Proposed are a storage apparatus and a control method thereof capable of improving the response performance to a read access of various access patterns. When data to be read is not retained in a data buffer memory, upon staging the data to be read, a processor performs sequential learning of respectively observing an access pattern in units of blocks of a predetermined size and an access pattern in units of slots configured from a plurality of the blocks regarding an access pattern of the read access from the host apparatus, and expands a data range to be staged as needed based on a learning result of the sequential learning.

Abstract: A fuel supply device supplying a fuel stored in a fuel tank to an engine includes a low-pressure pump configured to feed the fuel, a high-pressure pump configured to compress the fuel discharged from the low-pressure pump and to feed to the engine, a first low-pressure passage member configured to define a first fuel passage from the low-pressure pump to the high-pressure pump, and a second low-pressure passage member configured to define a second fuel passage branched from the first fuel passage at a low-pressure junction portion and joining the first fuel passage at a low-pressure confluence portion, wherein the first fuel passage and the second fuel passage are different in at least one of (i) temperatures of the fuels that flow through the fuel passages and (ii) passage lengths of the fuel passages from the low-pressure junction portion to the low-pressure confluence portion.

Abstract: A storage apparatus according to one aspect of the present invention includes one or more storage devices and a storage controller. The storage controller separates an area of the storage device into an overwrite storage area and an append write storage area and manages the areas, and moves data between the overwrite storage area and the append write storage area. For example, less frequently updated data among write data from a host is moved to the append write storage area from the overwrite storage area. In a state where update data directed to the data stored in the append write storage area is received from a host, the storage controller compresses the update data and then performs append write of the compressed update data to the append write storage area.

Abstract: An abnormality diagnosis apparatus is an apparatus that diagnoses a fuel leak from a fuel passage to circulate a liquefied gas fuel between a fuel tank and an internal combustion engine. The abnormality diagnosis apparatus includes: a control device; a low-pressure temperature sensor arranged at a discharge port of a feed pump; and a high-pressure temperature sensor arranged at an overflow fuel emission port of a supply pump. The control device detects a decrease in the temperature of the liquefied gas fuel at the overflow fuel emission port on the basis of a comparison between the measured values of the two temperature sensors, thereby determining that the fuel leak is caused in a section from the discharge port to the overflow fuel emission port.

Abstract: A fuel supply device includes a sub fuel tank disposed in a return fuel line, a pressure reduction valve, and a recirculation cutoff valve. When an internal combustion engine stops, the fuel supply device opens the pressure reduction valve and closes the recirculation cutoff valve. Due to this first transfer state, a liquefied gas fuel in a common rail is transferred to the sub fuel tank. Thereafter, the fuel supply device closes the pressure reduction valve and opens the recirculation cutoff valve. Due to this second transfer state, the liquefied gas fuel in the sub fuel tank is transferred to a main fuel tank. The fuel supply device repeatedly alternates between the first and second transfer states to collect the liquefied gas fuel from the common rail to the main fuel tank.

Abstract: Each actual page inside a pool is configured from a plurality of actual tracks, and each virtual page inside a virtual volume is configured from a plurality of virtual tracks. A storage control apparatus of a mainframe system has management information that includes information denoting a track in which there exists a user record, which is a record including user data (the data used by a host apparatus of a mainframe system). Based on the management information, a controller identifies an actual page that is configured only from tracks that do not comprise the user record, and cancels the allocation of the identified actual page to the virtual page.

Abstract: A host I/F unit has a management table for managing an MPPK which is in-charge of the control of input/output processing for a storage area of an LDEV, and if a host computer transmits an input/output request for the LDEV, the host I/F unit transfers the input/output request to the MPPK which is in-charge of the input/output processing for the LDEV based on the management table, an MP of the MPPK performs the input/output processing based on the input/output request, and the MP of the MPPK also judges whether the MPPK that is in-charge of the input/output processing for the LDEV is to be changed, and sets the management table so that an MPPK which is different from the MPPK that is in-charge is to be in-charge of the input/output processing for the LDEV.
