Patent GB-910595-A (GB)
IPC: F16H63/30
Abstract: 910,595. Clutch control. SMITH & SONS (ENGLAND) Ltd., S. Feb. 20, 1959 [Feb. 21 1958], No. 5782/58. Class 80 (2). In a vehicle transmission system comprising an electromagnetic clutch 23 energized by an engine-driven generator 1, a first resistance 14 is connected between the armature 2 and the clutch, and a second resistance 4 is connected in series with the field winding 3, the first resistance being in circuit over a first opening range of movement of the pedal 11 from the throttle-closed position and the second resistance upon movement of the pedal beyond the first range. Pedal 11 operates cams 9, 15 controlling contacts 8, 12 and 13, and 16, respectively. Initial movement of pedal 11 closes contacts 8, 12 so that clutch winding 22 is energized through resistance 14, contacts 16 being closed to shortcircuit resistance 4. Further movement of the pedal closes contacts 8, 12, 13, thus connecting the clutch winding directly to contact 8, and at the same time contacts 16 open to connect resistance 4 to the generator field circuit. When the vehicle speed reaches a predetermined value a governor 31 operates to open a contact 29, a relay contact G1 closes contact 19 and contact G2 is closed, whereby the clutch is energized from the battery 24 through a line 27 including the ignition switch 26, resistance 4 being short-circuited to restore the generator field circuit. During gear changes contact 32 is closed and if governor contact 29 is open the clutch is completely de-energized on account of relay contact C1 being open. If contact 29 is closed, due to the vehicle being at rest or moving slowly, the clutch is only partially de-energized, a small current flowing through resistance 28 and contacts 18, C2, 19, G1. In a first modification, Fig. 3 (not shown), resistance 14 is provided with intermediate tappings, and in a second, Fig. 4 (not shown), contacts 13, 16 are replaced by a normally closed contact in parallel with resistance 14 and a normally open contact in parallel with resistance 4. The clutch 23 may be of the magnetic powder type as described in Specification 649,553.

Title: Disc array recording system
Inventor: OGAWA AKIRA
IPC: G06F11/10
Filed: 1994-05-09
Abstract: A temporary write area is provided for each disc. When data are read, updated and re-written, the data are re-written to the temporary write area. Since the re-writing does not require a full disk rotation, the writing occurs quickly. Data in the temporary write area are relocated into the disk during an idle state, without being synchronized. Additionally, corresponding blocks in data areas can be used for writing data rather than a specified temporary write track. In order to improve re-writing time, the rotation of the disk drives can be synchronized to avoid full rotations between reads and writes, or cache memories for each disk can be used. When data is accessed from a host computer in a first unit size and from the memory devices in a second unit size, a buffer and cache can be used to limit the written data to those portions of the second unit size which have been changed. Each of these devices reduces the total access time for writing to arrayed recording devices. <IMAGE>
