Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an empty buffer while executing a write request from a host device even though the data transfer rate between the device is slow. SOLUTION: The write data, which are transferred from the host device in accordance with the write request from the device, are temporarily stored in a write buffer region, a preparation is made for a writing operation within the requested range and an operation is started to write the data stored in the buffer region into a disk medium. Then, the amount of data accumulation in the write buffer region is measured twice with an interval of time dt (steps S6 to S10). If the amount is being reduced, a difference da (an amount of the reduction) of the twice-measured amounts a1 and a2 is obtained, a minimum size in the write buffer region a(=tx(da/dt)) is obtained from a reducing speed da/dt, which is obtained by the difference da and the time dt, and a time t, which is the time required for the medium to make one revolution (steps S11 to S13), and a resetting is made.

Title: Fault detection circuit for switching element
Inventor: OOSAWA YOSHINOBU
IPC: H02H7/20
Filed: 1978-06-14
Abstract: PURPOSE: To realize a quick and high-reliability detection for the fault through a simple constitution by detecting the output terminal voltage of the switching element via the voltage detector of the pulse transformer or the like and then controlling the other switching element.  
     CONSTITUTION: When the voltage between the collector and the emitter of switching element 3 is turned on and off by the control of detector 4, pulse transformer 8 delivers the pulse voltage at the rise and fall parts of the voltage between the collector and the emitter of element 3. The positive pulse voltage switches transistor Tr11 on to discharge the electric charge of capacitor 13. In case elememt 3 is normal, the voltage stored in capacitor 13 is discharged repetitively by the output of transformer 8 and via Tr11. However, if element 3 is short-circuited or opened, transformer delivers no pulse voltage. As a result, Tr11 is never switched on. And when the charging voltage of capacitor 13 rises up to reach the reference level, UJT14 operates to dirve relay 15 with contact 16 closed. Thus the fault signal of element 3 is detected at detector 17.

Title: Method and apparatus for controlling inclination of air cushion type support
Inventor: TAKAHASHI NORIO
IPC: B65H20/10
Filed: 1978-06-15
Abstract: PURPOSE: To restore the transported object on the air cushion type support to the normal position by the compressed air being blown from the carrying surface, by detecting the amount of offset generated in the transported object, and by inclining the axis of the support correspondingly to the deviation from the reference value.  
     CONSTITUTION: The strip 2 is supported above the carrying surface 3a of the air cushion guide (floating head) 3; the transverse offset of the strip 2 is detected by the detector 4, and its output voltage is compared with the set reference value by the comparator 6. Responding to the output of the comparator 6, the controller 7 controls the motor 9, and the output shaft 12 is moved, and an end of the supporting parts 13 is moved to one side. Hereby, the resultant force being given to the strip 2 by the compressed air being blown from the carrying surface 3a, generates a force to restore the strip 2 to the original position. By this restoring force, the strip 2 moves toward the original position, and when the offset to be detected by the detector 4 besomes zero, the strip 2 restores the normal position.

Title: Pelton water-wheel
Inventor: TAKIGAWA YUTAKA
IPC: F03B15/20
Filed: 1984-04-13
Abstract: PURPOSE:To improve the reliability of operation in flood by suppressing the flow-out of compressed air by installing a recovery apparatus for the compressed air into an outlet conduit. CONSTITUTION:An expandable weir 13 formed because of the elasticity of reinforced rubber, etc. is installed onto the bottom part of an outlet conduit 12. A recovery chamber 18 for compressed air is installed at the top of the outlet conduit 13 opposed to the weir 13. The recovery chamber 18 communicates to a runner chamber 1. When a detector 11 detects the rise of the water level in flood, the compressed air is supplied into the runner chamber 1 by a compressor 9. At the same time, the compressed air is supplied also into the weir 13, which expands. Therefore, the discharged water forms the flow directing upward by the weir 13, and the separation of the compressed air mixed is faciliated. The compressed air which is separated is returned into the runner chamber 1 from the recovery chamber 18.

Title: Control circuit of first-in and first-out register
Inventor: ITOI TETSUSHI
IPC: G06F5/06
Filed: 1982-04-30
Abstract: PURPOSE:To prevent the generation of noises, by fetching in advance an input signal with a shift-in clock and then interrupting a shift-out clock when the number of frame-based shift-in clocks is larger than the shift-out clocks. CONSTITUTION:A power supply is applied to generate a signal IR, and this signal IR is turned into a master reset signal MR via an OR8 to clear a counter 11 after waveform shaping 9 and 10. Then the counter 11 counts shift-in clocks SI, and then an FF12 is set to deliver an input to AND14 and 13 respectively. Then the shift-out clocks SO and the clocks SI are counted 15 and 16 and then latched 17 and 18. Signals A, SI and SO are supplied to a de-jitter part 1 consisting of a first-in/first-out register from a correcting circuit (not shown in the diagram). Then the part 1 delivers a signal B. A comparator 19 delivers an output when a latch output Y becomes larger than a latch output X, and the signal MR clears the counter 11. Then the FF12 is reset to turn off the AND13 and 14. Thus the counting is discontinued, and the counters 15 and 16 are cleared. This prevents the generation of noises.
