Title: Fuel assembly
Inventor: KAWATA TOKUO
IPC: G21C5/18
Filed: 1988-09-29
Abstract: PURPOSE:To improve a void reactivity of a coolant continuously through a fuel cycle by loading a plurality of fuel rods to be as fuel rods containing a burnable poison at positions in intermediate layers and inner layers of a fuel arrangement. CONSTITUTION:A fuel assembly is constituted with a plenty of fuel rods of an outer layers 10, intermediate layers 12 and inner layers 14, all arranged on coaxial circles. In this arrangement, fuel rods 12a of the intermediate layers and the inner layers which contain a burnable poison have a large neutron absorption rate; therefore, a reactivity change by an existence of light water or non (a void ratio) is rather small. With this reason, a void reactivity of coolant in the whole system shifts towards a negative side in comparison with fuels not containing a burnable poison. An amount of the burnable poison decreases gradually and the effect described above decreases also. However, fuel rods containing the burnable poison are used for a plurality of fuel rods in the intermediate layers and thus the void reactivity of coolant can be suppressed to stay at a negative side continuously through a fuel cycle.

Title: Reproducing device for magnetically recorded data
Inventor: KUBO TAKASHI
IPC: G11B20/14
Filed: 1990-09-17
Abstract: PURPOSE:To accurately read out data by recording the data in a recording system for showing '0' and '1' depending upon whether or not magnetization inversion should be performed by 1/2 of a reference bit length. CONSTITUTION:When a start mark reaches a magnetic head, and a pulse signal having a short period is detected by a start mark detecting circuit 25, a contact B of a changeover switch 26 is short-circuited, and an initial bit space is inputted from a data bit detecting circuit 28 to a bit space setting circuit 27, and is inputted as it is to the circuit 28. A discriminating space is calculated by the circuit 28 based on the initial bit space, and a pulse signal of film information to be inputted from a binarization circuit 22 is discriminated. That is, when an output level of one bit is not changed by the discriminating space, it is discriminated a s'0', and when the level is changed, it is discriminated as '1'. Then, even when the immediately prior bit space is changed by changing a film traveling speed, the discriminating space is changed to follow this, so that the accurate discrimination is carried out. By this method, the film information is accurately read out without being influenced by a change in the film traveling speed.

Abstract: PROBLEM TO BE SOLVED: To obtain satisfactory print state by maintaining a once set printing pressure constant irrespective of rise or fall of a plate holder without fine fluctuation of an image due to vibration of a screen plate at the time of printing. SOLUTION: A plate holder 3 of a plate mounting mechanism B is separated from a printing mechanism C and solely vertically moved. Thus, in the case of reciprocating a squeegee 13 and doctor 14 of the mechanism C at the time of printing, even if a vibration occurs at the mechanism C due to an impact generated at the time of starting or stopping its moving, the vibration is not directly transmitted to the holder 3 of the mechanism B, and vibration generated at a screen plate 5 of the holder 3 is suppressed. Further, the holder 3 of the mechanism B is vertically moved, but reciprocating traces of the squeegee 13 and doctor 14 in the mechanism C are not vertically changed, and parallelism is held irrespective of the vertical movement of the holder 3 to a matter-to-be- printed positioning surface 2a of a table 2.

Abstract: PURPOSE:To provide a magnetic coating exhibiting excellent dispersion of magnetic powder, prepared by blending a polymer which contains a residue of tetrahydrofurfuryl ester of an ethylenically unsatd. aliphatic carboxilic acid, a solvent for the polymer and magnetic powder. CONSTITUTION:A polymer which contains 5-95wt% at least one residue to tetrahydrofurfuryl ester of an ethylenically unsatd. aliphateic carboxylic acid in the molecule, magnetic powder and a solvent for the polymer are blended together.
