Title: Hydraulic cargo handling device
Inventor: TOMARU HITOSHI
IPC: B66F19/00
Filed: 1990-08-09
Abstract: PURPOSE:To change over a manual mode and balance mode with a change-over valve for accurately locating a workpiece by providing a manual operating valve for supplying pressure oil to a contraction chamber of a hydraulic cylinder and a balance valve for adjusting workpiece weight and pressure in the contraction chamber so that both are balanced with each other. CONSTITUTION:When a manual operating valve 9 is set to a lifting position U while a mode change-over valve 11 is set to a position II, pressure oil in a pressure oil source 7 is supplied to a contraction chamber 3 of a hydraulic cylinder 1 to lift a workpiece 6. When the valve 9 is set to a lowering port position, the workpiece 6 is lowered and when set to a neutral position N, the workpiece 6 stands still to provide a manual operating mode. When the valve 11 is set to the position II while the valve 9 is set to the neutral position N to float the workpiece 6 in the air after the workpiece 6 is lifted, pressure in the chamber 3 is stored in a volume 15. Thus, pressure oil is supplied to the chamber 3 by a balance valve 10 to provide a balance mode so that the pressure in the volume 15 acts on the workpiece 6 to be manually easily located.

CONSTITUTION:A roof is constituted with a plurality of roof elements 1 radially divided, and the elements 1 are jointed with hinges 2. Also, the grouped top 4 of each element 1 is supported with a screw jack 5, and a movable nut 6 screwed into the screw jack 5 and a rotary core member 7 pivotally supported on the grouped top 4 are connected to each other with a lever 8. In this case, when the screw jack 5 is driven to rotate with a motor 9, the nut 6 moves vertically, and the rotary core member 7 opens or closes about the grouped top 4. Furthermore, the roof element l connected to the rotary core member 7 rotates thereabout, and the shape of the roof changes. Also, mean peripheral length formed with the external surface of each element 1 changes. As a result, recessed walls 14 and the corner columns 10 thereof move respectively along rails 16 and 15. According to the aforesaid construction, a building area increases or decreases as well, according to a change in the peripheral length of the roof. Also, the roof and wall can be fixed at a desired position.

Title: Magnetic recording disk and its manufacture
Inventor: KAWAMATA TOSHIO
IPC: G11B5/845
Filed: 1992-07-15
Abstract: PURPOSE:To perform a high-density recording by allowing a ferromagnetic metal powder to have a coercive force which is equal to or more than 1400 oersteds, an orientation degree ratio in horizontal direction of 0.85 or more, a squareness ratio in vertical direction of 0.3-0.65, and an orientation degree ratio in vertical direction of 0.85 or more. CONSTITUTION:A ferromagnetic metal powder has a coercive force of 1400 oersteds or more and the thickness of the magnetic layer is set to 0.5mum or less. Since the thickness of the magnetic layer is extremely thin, self demagnetization, recording demagnetization, and a loss such as thickness loss are reduced and the output at a short wavelength region is increased. The ratio of the orientation degree in horizontal direction is controlled to be 0.85 or more, thus preventing output fluctuation in a circumferential direction. Also, the squareness ratio in vertical direction of diamagnetic field compensation is set to a range of 0.3-0.65. Namely, the magnetizing direction of the ferromagnetic metal powder is controlled skewly in reference to the magnetic layer surface. Also, since the ratio of the orientation degree in vertical direction can be controlled to be 0.85 or more, recording demagnetization can be reduced and reproduction output and electromagnetic conversion characteristics such as modulation can be improved, thus obtaining a high-capacity magnetic recording disk suitable for high-density recording.

Title: Input/output controller
Inventor: SUGIURA HAJIME
IPC: G06F13/10
Filed: 1990-08-10
Abstract: PURPOSE:To efficiently use a channel by discriminating whether a record retrieval system fits to an internal retrieval system or not and retrieving a record by means of the internal retrieval system only when it fits to the internal retrieval system. CONSTITUTION:When a comparison means 18 discriminates two search commands and two pieces of search data to be coincident, a second search command execution means 19 detaches connection with a channel 1, sequentially reads the records from a storage device 2 in a detached state and retrieves the record concerned designated by search data. When the first search command and following search data are coincident, connection with the channel 1 is detached and the record is retrieved without responding to the channel 1 at every execution of the search command until the record concerned is found or the retrieval of all the records is terminated in a controller. Thus, the channel can efficiently be used.
