Title: Method and device for measuring nuclear fission material
Inventor: YASUOKA MAKOTO
IPC: G21C17/06
Filed: 1991-03-18
Abstract: PURPOSE:To enable exactly measuring fissile material without effect of ray by radiating thermal neutron through a neutron moderator to a measured body contained in a neutron moderator body and detecting fast neutrons generated by nuclear fission. CONSTITUTION:A penetration hole 7 penetrating neutron moderator 4 in a containment vessel 2 constituted of neutron moderator material 5, 6 is formed. In this penetration hole 7, a nuclear fuel rod 8 as a measured body is contained detachably. Fast neutrons in pulse generated by the irradiation from a neutron generator 9 are moderated in the moderator 5, 6 to be low speed thermal neutrons and stay for a while in the moderator 4. A thermal neutron detection means 10 measures the behavior of these thermal neutrons with time. And a fast neutron detection means 11 discriminates in the measurement using the disappearing time of fast neutrons generated by irradiation between the fast neutrons generated by the irradiation and the fission neutrons generated by fission. Thus, based on the data from the detection means 10, fission material amount in the fuel rod 8 is measured. This device can be reduced in size and weight.

Title: Method and apparatus for controlling generation of minute alga which foul water
Inventor: IWATA ATSUO
IPC: C02F1/50
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of minute alga by arranging slag obtained directly from an incineration furnace or by melting and washing incineration ash on the surface of water to be treated, in the water, or on the bottom of the water. SOLUTION: A slag means 6 is set freely attachably/detachably in a water purifying filter 2 installed in the upper part of a water tank main body 1 to be contacted with water circulating through a pipe 5. In the slag means 6, granular slag formed directly from an incineration furnace or by melting and washing incineration ash is housed in a container. The volume of the container of the slag means 6 is determined by the circulation speed of water of a water circulating pump driven by a motor 4, i.e., a circulating flow rate. A lot of slits, holes, and others, which allow water to pass through but do not allow slag in the inside, are formed in opposite surfaces such as upper and a bottom surfaces, the slag means 6 is removed in cleaning, and the generation of minute alga which foul water can be controlled.

Title: Fracture-toughness measuring method
Inventor: NISHIYAMA ATSUSHI
IPC: G01N33/38
Filed: 1991-03-18
Abstract: PURPOSE:To improve the measuring accuracy of fracture toughness and to shorten the measuring time by forming a metallic thin film on the surface of a sample by vapor deposition before pressing Vickers indenter for generating indentations and cracks into the surface of the sample to be measured. CONSTITUTION:For example, gold is applied on a surface 1 of the mullite- sintered body of a sample to be measured by vapor deposition so as to obtain the thickness of about 50Angstrom . A Vickers indenter 2 is pressed into the surface 1 at the indenter load of 1kg, and indentations and median cracks are generated. For each indented part, crack lengths c1, c2, c3 and c4 in the four directions are measured. At this time, when the median crack enters into the base material of the ceramic sample, the same crack as the median crack is generated in the gold thin film formed on the surface 1 by the vapor deposition. Therefore, the reflected light from the surface 1 becomes uniform over the entire surface 1 by the vapor deposition of the gold thin film on the surface 1. Thus, the crack in the gold thin film can be visually recognized far more clearly than the median crack in the ceramic surface 1. Therefore, the measuring accuracy of the fracture toughness can be enhanced.

IPC: H03M7/08
Filed: 1983-03-29
Abstract: PURPOSE:To reduce the number of times of operation by decomposing binary data into blocks, each of which consists of a preliminarily determined number of bits, in order from the least significant bit and storing these blocks and converting blocks to decimal data in order from the low-order block and shifting up data in accordance with positions occupied by blocks to add data successively. CONSTITUTION:First, counters 10 and 15 are cleared to 0, and binary data in a register 14 is transferred to a shifter 18 through a selecting circuit 16 and an adding circuit 17, and, for example, the lowest 4 bits of data are sent to a latch circuit 12. A corresponding address of a converting circuit 13 is accessed in accordance with contents of the latch circuit 12 and the counter 10 to convert this 4-bit data to decimal data, and this decimal data is added to contents of the register 15 by the adding circuit 17, and the result is shifted by the shifter 18 and is stored in the register 15, and the counter 10 is counted up. Next, binary data from the register 14 is transferred to the shifter 18, and the next lowest 4 bit are subjected to the similar processing. This operation is repeated to convert binary data in the register 14 to decimal data, and decimal data is stored in the register 15. Thus, the number of times of converting operation is reduced to 1/4.

Filed: 1990-03-05
Abstract: PURPOSE:To constitute a file management function for memory by providing a data protect unit for dividing information from the outside into the reloadable and unreloadable regions of EEPROM and transmitting said information. CONSTITUTION:Because EEPROM3 can electrically reload information from the outside via CPU2 and store said information, the EEPROM attaches a protect code for making the information correspond to pages of a EEPROM3 for successively storing the information, for dividing the address in the EEPROM 3 into reloadable region (white part) and unreloadable region (part indicated by oblique lines) and for causing only the reloadable region to store the information. The protect code is constituted from the binary code of '1' or '0' and instructs the EEPROM3 that reloading of information to be stored is permitted or not, and '1' indicates reloadable instruction while '0' indicates unreloadable instruction. Normally, peculiar information such as a card user's secret code number and personal history is cited as information making reloading impossible and business data, past record of a car itself, etc., are cited as information making reloading possible.
