Abstract: PURPOSE:To discharge water all over a coal storage heap through a small number of water discharge devices, by a method wherein an angle of elevation is specified at the central part of fan-shaped movement, and is gradually increased at both side parts. CONSTITUTION:When an arm-shaped part 6 is gradually rocked upward at both side parts of fan-shaped movement, an angle of elevation of a water discharge surface X, formed through fan-shaped rotation of a nozzle 8, with a horizontal plane is increased over alpha and is gradually increased to a high value betatoward the both sides of the fan-shaped movement, and after the nozzle 8 is turned over, a value is restored from beta to alpha. As a result, the flow of water discharged through the nozzle 8 is gradually risen approximately to a vertical state at both side parts of the fan-shaped movement, and a water discharge angle is gradually restored to its original value toward the central part. Thereby, when a water discharge flow approaches a ridge line, it is prevented from direct collapsion with the coal storage heap 1, and the water discharge flow is moved upward, and discharge of water to the upper surface of the coal storage heap 1 is continued as it is prevented from direct collapsion with the coal storage heap 1.

Title: Magnetic disk device
Inventor: URABE MASAYUKI
IPC: G11B19/02
Filed: 1989-04-20
Abstract: PURPOSE:To uniformize read margin performance of the device and to promote the throughput by deciding whether a received command is a dividing mode or not and dividing cylinders into odd cylinders and even cylinders when the dividing mode is decided. CONSTITUTION:When the command is received by a CPU from a host device, a target cylinder number 'N', an objective head and a target sector are calculated from an address. Then, whether the command is the dividing mode or not is decided, and when it is the dividing mode, the target cylinder number 'N' is multiplied by two to be '2N'. Then, whether the command is for a 2nd device or not is decided, and when it is 'YES', the target cylinder number '2N+1' is decided by adding one. The dividing processing is completed after seeking the cylinder on the '2N+1'th by sending a control signal to a positioning servo control circuit 11. By this method, the read margin performance is uniformized, thus shortening the access time to the 1st and 2nd devices.
