摘要： PROBLEM TO BE SOLVED: To improve a reprocessing speed of spent nuclear fuel and obtain a mixture of high-purity uranium and reusable plutonium in a simple process at low cost.
SOLUTION: Spent nuclear fuel 1 is fluorinated with fluorine 2 in a fluorination process 3 and the mixture of uranium and plutonium and fission products are separately recovered. The plutonium fluoride volatilizing in fluorination process is recovered together with a stabilization agent, and after passing an oxidation conversion process 8, recovered as a mixed oxide of uranium and plutonium. Since uranium is recovered at a high purity, control in reuse, storage and the like is very easy. As they are recovered as the mixture of uranium and plutonium, fuel refabrication cost can be lowered and non-proliferation characteristic can be increased. Due to dry type, device and processing facility can be made simple and so economy is improved and fuel refabrication cost can be lowered.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing hydrogen/oxygen particularly using a radioactive substance produced from a nuclear reactor or the like in the treatment of high level radioactive waste produced from the nuclear reactor or the like. SOLUTION: The following technical contents are provided as the constituting requirements of this invention. A radioactive material produced in the nuclear reactor or the like attenuates its radioactivity with the emission of γ. X-ray. The γ. X-ray is transformed to visible ray or ultraviolet ray by a scintillator. Water is decomposed by irradiating a photocatalyst with the visible ray or the ultraviolet ray to produce hydrogen and oxygen. The waste is stored in a water tank until the radioactivity is sufficiently attenuated to produce hydrogen and oxygen and after that, the waste is sent to a normal treatment process such as reclamation. The manufacturing apparatus is provided with a vessel for mixing and preserving the scintillator and the waste in the water tank and an apparatus for recovering the produced hydrogen and oxygen and can be constructed within the extent to which a conventional preserving apparatus is extended.

摘要： PURPOSE:To easily position a bar code reader and to improve the reading operability of the reader by providing a filter mirror on the upper surface of an opening part of the bar code reader to reflect the near infrared rays. CONSTITUTION:The bar code images of near infrared rays are reflected by a filter mirror 12 for reflection of near infrared rays. The bar code images formed by the peripheral external light (visible light) pass through the mirror 12. Thus the bar codes 6 set under an opening part can be viewed through via the mirror 12 of a bar code reader 11. As a result, the reader 11 can be easily positioned to the codes 6 and the reading operability is improved with the reader 11 since the codes 6 set under the opening part are not hidden by the reader 11 and can be viewed through.

摘要： PURPOSE:To confirm the completion of synchronization while taking synchronism through the transmission and reception of a specific pattern. CONSTITUTION:Prior to the start of correspondence of signals between an upper rank device 1 and a lower rank device 2, an optical transmitter 3 of the device 1 generates a specific pattern. This specific pattern is sampled at an electrooptic converter 6 and converted into an optical signal and transmitted to an optical transmitter 4 of the lower rank device 2 through an optical fiber 11. This optical signal is converted into an electric signal at a photoelectric conversion circuit 8 and inputted to a specific pattern detection circuit 13. At the same time, a synchronizing signal extracting circuit 9 extracts a synchronizing signal among outputted electric signals of the circuit 8 and specific patterns are restored based on the synchronizing signal. When a correct restoration is achieved, a signal representing the completion of synchronism is transmitted to the device 1 with a return circuit 14.

摘要： PURPOSE:To make information exchange between two series loops possible with inexpensive hardware, by coupling the two series loops with an information exchange device having a prescribed function. CONSTITUTION:Series loops 1 and 2 are coupled with each other by means of an information exchange device 3. The information exchange device 3 is provided with a prescribed function. Namely, the device 3 supervises loop number fields of information on the two series loops and propagates information having its own loop number to the lower-order loop line as it is. The device 3 draws up information having the other side loop number in a buffer provided in the device 3 and deletes the information from the loop. Then the device 3 sends the drawn up information synchronously to the transmission timing of the other side loop. Moreover, this device 3 is equipped with a bypass circuit which sets the two series loops to a one series loop condition. Therefore, information exchange between the two series loops can be performed with inexpensive hardware.

摘要： PURPOSE:To realize a high-speed conversion with no time delay, by installing a parallel signal holding circuit plus a comparator to obtain a disagreement detection signal of the input/output signals of the said holding circuit at the front stage of a shift register that is inputted by a parallel signal and the delivers the series signal by the clock signal. CONSTITUTION:The circuit 13 to hold the parallel input signal plus a comparator 12 which detects a disagreement between the input and output signals of the circuit 13 through a comparison are installed at the front stage of the shift register which supplies the parallel signals A-C and then delivers the series signal via the clock signal. Thus the parallel input signals are set to the circuit 13 and the register 11 to perform a parallel-series conversion by the disagreement detection signal showing the changing point of the parallel input signal. In such way, a high-speed transmission is possible for the data with no delay of time since a parallel-series conversion is given at the moment when the signal level is changed.

摘要： PURPOSE:To provide the display controller which performs the bit-by-bit approximate editing of screen data displayed with one number of dots and displays the data with the other number of dots, as to a display device which is different in the number of dots of one screen. CONSTITUTION:This display control circuit discriminates dot data before and after a display signal 33 of the screen which is large in the total number of dots by a dot decision part 37 and generates a display signal of the screen small in the total number of dots by converting the data into display data of the screen small in the total number of dots. Screen display data displayed on a high-function display can be displayed on a low-function display to provide the effect of replacement with an inexpensive, small-sized display device.

摘要： PURPOSE:To transmit frames which consists of various and large numbers of bits on time-division basis at a high speed by applying the frame with time division in bit unit and modulation to the result to make it a binary AMI code, and transmitting a specific original transmit code while inverting ''1'' and ''0'' to that of another original transmit code. CONSTITUTION:Two opposite couples of transmitters 1A and 2A, and 1B and 2B are connected to the optical communication path 4 consisting of optical converters 5 and 6 and an optical fiber X by using multiple centralized distributing devices 3 and 8, and asynchronous transmit frames of both systems A and B are multiplexed, bit by bit, on time-division basis to perform digital transmission. In this case, original transmit codes are modulated into binary AMI codes of frequency which is twice as high as the frequency of multiple centralized distribution, and ''1'' and ''0'' corresponding to a specific original reference transmit code among the binary AMI codes are inverted to ''1'' and ''0'' corresponding to other original transmit codes and transmitted between the devices 3 and 8. Consequently, frames are transmitted at a high speed and synchronization is facilitated.
