Title: Disposal method of radioactive sodium waste
Inventor: KARITA YOICHI
IPC: G21F9/06
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To process radioactive sodium waster safely and inexpensively in a short period, by electrolyzing the radioactive sodium waste through a sodium conductive partition and collecting the product on the cathode side, converting sodium into a sodium compound in a reactor, and thereafter processing and storing as a solid or liquid. SOLUTION: When electrolysis is executed through a sodium conductive partition in an electrolytic bath 1 by using radioactive sodium waste as an anolyte at 120-800 deg.C, preferably, at about 200-300 deg.C, only radio-activated Na22 passes the sodium conductive partition and moves to the cathode side, to collect sodium not including various radioactive nuclides, such as plutonium or the like. Then, the sodium obtained in the electrolytic bath 1 is introduced into a sealed reaction tower 2, and reaction gases, such as CO2, SOx, Cl2, HCl, steam or the like, are made to function therewith to obtain a stable sodium compound. And, the sodium compound is changed into a solid form, for example, drum packing, pellet or the like, or into a liquid form by dissolving it in water, and stored as long as a prescribed period until a half-life (2.6 years) passes, and then discarded.

Title: Malfunction detector for exhaust gas recirculating temperature sensor
Inventor: OUCHI YASUSHI
IPC: G01K7/24
Filed: 1987-12-14
Abstract: PURPOSE:To perform the malfunction of a sensor accurately by judging a specified state with a driving state detected, comparing a sensor output signal obtained by a means converting a signal out of an EGR temperature sensor for the specified state alone, with the specified value and, when it is less than the specified value, so judging that the sensor is out of order. CONSTITUTION:When a control circuit is energized with current, a judgment of whether it is a specified state (for example, starting completion or the like) or not from a variety of input information is carried out at the central processing unit, and when it is not the specified state, transistors Q1, Q2 in an interface are turned to ON, making the control circuit perform its normal signal conversion. On the other hand, when it is the specified state, these transistors Q1, Q2 are turned to OFF, selecting it to the signal conversion of the specified state alone. Next, an output value of an EGR temperature sensor 3 partially divided by resistors R1, R2 is stored in memory, comparing this output value with the specified value. When it is less than the specified value, it is so judged that the sensor is normal, while when it is more than the specified value, it is so judged that the sensor is out of order.

More specifically, outputs from cells #6 and #31 are added by LFSR at an exclusive OR gate 14 according this system and the output from gate 14 is delivered to an exclusive OR gate 13. The gate 13 adds the output from cell #2 thereto by modulo 2 system.

Title: Electromagnetic driver
Inventor: ICHII YOSHITAKA
IPC: H02K33/06
Filed: 1994-12-22
Abstract: PURPOSE: To ensure a sufficient thrust even if a mover block is displaced significantly from a stationary reset position by spreading the flux in a magnetic air gap, defined by a side leg piece and the pole face of a permanent magnet, on the stator side by a predetermined angle outward with respect to a reference line extending is parallel with the axis of a central leg piece. CONSTITUTION: Side leg pieces 2b, 2b decrease in height gradually toward the center. With reference to a pole face 2A, the outer side is higher than the pole face 2A while the inner side is lower than the pole face 2A and the inclination is set at 1/7. Since the pole faces 2B, 2B recede gradually from a permanent magnet 5 toward the inside and do not extend in parallel with pole faces 5A, 5B, flux in a magnetic air gap G facing the pole faces 2B, 2B flows to spread outward by a predetermined angle on the stator side with respect to a reference line extending in parallel with the axis of a central leg. Consequently, the effective component of flux is increased for the movement of a mover block.
