摘要： When a disk controller receiving an access from a host computer to a disk device is connected with a disk connection device, if a relevant disk is used by another disk controller, positioning data for seek, set file mask and set sector are queued in a common memory. When the relevant disk becomes free, the disk controller reads the queued information and requires the disk device for positioning. A request of a reconnection with the host computer is issued from the disk controller informed by the disk unit, which has finished positioning at the position specified by the positioning data, search of an aimed record and a read/write operation of transmitted data are effected without any new intervening of an access program of the host computer.

摘要： There is disclosed an error recovery apparatus and method for a data processing system having (1) a peripheral unit, for instance, a magnetic disc unit, for storing data in a plurality of blocks each having a unique address, (2) a main memory for storing data read from the peripheral units, and (3) a controller for controlling the transfer of the data blocks from the peripheral unit to the main memory by execution of a single channel command word (CCW) chain. When an uncorrectable error occurs in the transfer of a second or subsequent data block of the plurality of data blocks (not the first data block), the processor produces a new CCW chain to re-read the data block in error in addition to all the data blocks subsequent to the data blocking error and store these data blocks in the memory under the control of the new CCW chain.

摘要： A storage system connected to host processors through data transfer paths includes at least one storage unit for moving a head for reading/writing the data relatively to a storage medium to read/write the data from/to the storage medium, and a controller for controlling the data transfer between the host processors and the storage units. The controller obtains and stores, every data transfer path, the information relating to the delay time which occurs when transferring the data through the data transfer path of interest. When an I/O request is issued from the host processor, in accordance with the measured information of the delay time in the data transfer paths, a request for positioning the head near the position on the storage medium in which the data is stored which is to be read/written is issued. In addition, when posting the release of the wait state to the host processors which had issued the I/O requests and are made wait the completion of the processings for other I/O requests, the order of issuing the notification is determined in accordance with the delay time in the data transfer paths which are permitted to be used in order to process the I/O requests.

摘要： When recording records into the IC memory group of a magnetic disk subsystem the records being composed of a count area of a fixed length, key area of a variable length and a data area of a variable length, data of a special format which is judged by ECC check to be an abnormal data is written at the top of the count area in each record. When reading an object record from the IC memory group, it is judged by ECC check whether or not the read data is an abnormal one. When the read data is judged to be an abnormal one, the read data is compared with the data of special format, and when there is found a coincidence between them, it is recognized that the read data are at the top of the count area. When writing data, data which are judged by ECC check to be a normal are suffixed to data which are judged by ECC check to be abnormal. When the read data are judged by the ECC check to be abnormal and judged by a next ECC check to be normal, it is recognized that the read data are at the top of the count area.

摘要： A method, apparatus and computer program for controlling data migration in an information processing system which includes a central processing unit (CPU), a new storage system connected to the CPU and an old storage system connected to the new storage system. In the information processing system data migration is conducted to transfer data from the old storage system to the new storage system. The invention operates by permitting access by the CPU to the storage systems during data migration. When an access by the CPU is generated the invention determines whether the access is to a region where data migration has been completed or to a region where data migration has not been completed. If the access is to a region where data migration has been completed, then processing of the access is handled by the new storage system. If the access is to a region where data migration has not been completed, then processing of the access is handled by the old storage system causing data related to the access to be transferred from the old storage system to the new storage system. The speed of data migration can be adjusted based upon the utilization of the resources of the information processing system and information of the priority of access to the new storage system by the CPU.

摘要： An engine valve operating system is provided in which one end of a first link arm (61) turnably supported at a fixed position of an engine body and the other end of a second link arm (62) turnably supported by a displaceable movable shaft (68a) are turnably connected to a rocker arm (63) which has a cam abutting portion (65) abutting against a valve operating cam (69) and is interlocked and connected so as to apply a force in a valve opening direction to an engine valve (19) biased by a valve spring (24) in a valve closing direction. A rocker arm biasing spring (54) which is different from the valve spring (24) biases the rocker arm (63) in a direction in which the cam abutting portion (65) abuts against the valve operating cam (69). This ensures follow-up ability of the opening/closing operations and enables a reduction in the size of the system, while allowing the lift amount of the engine valve to vary continuously. It is also possible to improve the accuracy with which the lift amount is controlled when the engine valve is to be slightly opened.

摘要： A hydraulic tappet including: a bottomed cylindrical body; a plunger slidably fitted in the body; a check valve mounted at one end of the plunger so that the check valve is interposed between a high-pressure chamber and an oil chamber, the high-pressure chamber being formed between a closed end of the body and one end of the plunger, the oil chamber being formed within the plunger; and a return spring mounted between the body and the plunger to bias the plunger in a direction to increase the volume of the high-pressure chamber. The return spring is disposed outwardly of the body. Thus, it is possible to decrease the volume of the high-pressure chamber to provide a reduction in size of the hydraulic tappet.

摘要： An engine valve operating system is provided in which a rocker arm (63) linked and connected to an engine valve (19) and has a cam-abutting portion (65) to abut a valve operating cam (69) is turnably connected, via first and second connecting shafts (64, 66), to one end of a first link arm (61) turnably supported on an engine body (10) and one end of a second link arm (62) turnably supported by a displaceable movable shaft (68a). Also, oil supply means (58) which supply oil to the upper connecting shaft (64) of first and second connecting shafts (64, 66) are fixed to the engine body (10). This makes it possible to implement an engine valve operating system which is compact in size, ensures follow-up ability of the valve opening/closing operation, has a simple lubricating structure with a reduced number of parts, and ensures smooth valve operation while allowing the lift amount of the engine valve to be varied continuously.
