Title: Dma transfer control system
Inventor: TAKEMURA TETSUO
IPC: G06F13/28
Filed: 1984-03-02
Abstract: PURPOSE:To accommodate lots of I/O devices and also to attain miniaturization and economy of the device by providing a transfer request cue storing a transfer request from each I/O and a data register storing temporarily a transfer data. CONSTITUTION:The transfer request cue 8 storing the transfer request from each I/O and the data register 3 storing temporarily the transfer data corresponding to each I/O are provided to a direct memory access DMA controller 2 (DMAC2). When the I/O 1-2 generates a request, the I/O 1-2 gives a transfer request to a signal line 104. When a permission signal is outputted from a control circuit 13 according to the request signal, a data is written in the register 3 and the device number is written in the cue 8. Then the data in the register 3 is transferred according to the transfer request stored in the cue 8 by the control of the circuit 13. Lots of the I/O devices are attained by providing the transfer request cue 8 and the data register 3 in this way and the miniaturization and economy of the device are attained.

Title: Moderator vessel for cold neutron source device
Inventor: KUMAI TOSHIO
IPC: G21G4/02
Filed: 1995-02-27
Abstract: PURPOSE: To obtain uniform cold neutrons efficiently by constituting the vertical cross section of a vessel in the neutron movement direction in roughly funnel shaped. CONSTITUTION: Moderator 2 boils and generates bubbles 11 due to nuclear heating such as fast neutrons mixed in thermal neutrons and γ-ray etc. Even in the case that bubble 11 existence is larger for higher elevation in the moderator vessel 1, relative existence amount of moderator 2 does not reduce as the vertical cross section is roughly funnel shaped, practical length of movement of thermal neutrons in the moderator becomes constant, and cold neutrons can be obtained efficiently and uniformly in the whole vessel 1. Also, as the upper open wall surface is slanted, bubbles 11, if generated, move up smoothly without stagnation of bubbles 11, which brings in a benefit to stabilize the cold neutron.

Abstract: PROBLEM TO BE SOLVED: To improve an antislipping effect by forming a side surface of a main frame upper end part having a flat upper surface in a recess/projection surface shape having plural projecting parts and recessed parts alternately juxtaposed in the lengthwise direction of main frames. SOLUTION: A grating as a groove cover of a groove arranged on a road surface is formed by joining both ends of a large number of main frames 4 juxtaposed at intervals to a pair of left/right vertical frames and also joining both ends of an intermediate frame joined to an intermediate part of the main frames 4 to a horizontal frame. Next, in the main frames 4, an upper surface 4t is formed as a horizontal flat surface, both side surfaces 4us of an upper end part 4u are formed in a zigzag shape having a large number of projecting parts (a) and recessed parts (b) alternately juxtaposed in the lengthwise direction of the main frames 4 in a plan view, and a recess/projection surface and both side surfaces 4ds of a lower plate part 4d are connected by an inclined connecting surface (s).  Thus, even when walking on a grating in either direction, since both side edge parts alternately provided with projecting parts and recessed parts sufficiently hitch on the sole of a shoe, a sufficient antislipping effect can be exhibited, and since upper surfaces of the main frames are flat, stumbling and rattling at carriage traveling time can be prevented.

Abstract: PURPOSE:To release a mechanical stopper smoothly at all times by arranging so that the final step of a mechanical stopper halts at a place slightly apart upward from a latch section of an oil hydraulic cylinder during a full tilt of a cab. CONSTITUTION:The upper end of a piston rod 12b of an oil hydraulic cylinder 12 which makes a cab tilt is pivoted on a bracket 8, and a latch section 12c is formed on the upper end of the cylinder 12.

Abstract: PURPOSE:To stabilize the rolling control by setting a scale factor within a prescribed range in the case that a response time constant for constant tension control for a rolled stock exceeds a specific value for a hydraulic draft type rolling mill whose mill rigidity is made to be variable. CONSTITUTION:A hydraulic draft rolling mill whose mill rigidity is made to be variable is provided with a displacement detector 8, a servo valve 10, coefficient multipliers 20, 23, and arithmetic units 21, 22. A load variation  P found based on a rolling load P and a lock-on value PL of the rolling load is inputted to the coefficient multiplier 20, which calculates  P/M (rigidity modulus) and the coefficient multiplier 23 calculates a scale factor KA and performs draft control. In the case that a time constant of tension constant control exceeds 0.2 sec, the scale factor KA is set to a value in the range from 0.5-0.8. The rolling control is stabilized because the mill rigidity control is stabilized.

Abstract: PURPOSE:To prevent the transmission of the vibration in the driving shaft direction of an electric motor and the generation of an abnormal sound by inserting the driving shaft of the electric motor to the blade boss of a blade, and spirally fitting a blade fastening fitting to the driving shaft with a spring being interposed between itself and the blade boss. CONSTITUTION:An electric motor 3 is fixed to the side plate on the intake port opposite side of a fan casing 1, and its driving shaft 4 is inserted to a point where a u-ring 5 locked by the driving shaft 4 is made into contact with one end face of the blade boss 8 of a centrifugal fan 2. A blade fastening fitting 7 is spirally fitted to the screw part formed on the top end of the driving shaft 4. In this case, a spring 6 is interposed between the blade fastening fitting 7 and the other end face of the blade boss 8. Hence, when a root vibration in the driving shaft 4 direction is generated from the electric motor 3, this vibration is absorbed by the spring 6 to prevent the generation of an abnormal sound.
