Title: Loop-type fast reactor
Inventor: OGURA KENJI
IPC: G21D5/12
Filed: 1995-01-11
Abstract: PURPOSE: To prevent a cover gas from being entrained from a free liquid surface during steady driving, and securely keep a core and structural materials sound. CONSTITUTION: An intermediate heat exchanger 8 is set in an intermediate gas exchanger vessel 7. A horizontal diaphragm 9 is set at the lower part of the intermediate heat exchanger 8. A flow shrouding 14 penetrating a lid 12 is arranged to cover an upper outer peripheral face of the intermediate heat exchanger 8. A horizontal plate 32 with many holes is disposed to cover an outer peripheral face of a lower end part of the flow shrouding 14. A cylindrical body 33 penetrates the horizontal plate 32 and diaphragm 9. A liquid level penetration device 20 is inserted in the cylindrical body 33. An upper end of the cylindrical body 33 surrounding the device 20 is opened to be higher than a liquid level 15 of a liquid metal during normal driving and lower than a liquid level 16 at the stopping time. A lower end of the cylindrical body 33 is opened in a lower plenum area of the diaphragm 9. The horizontal plate 32 restricts the oscillation of the liquid level and entrainment of a gas, and the cylindrical body 33 reduces the thermal stress into the intermediate heat exchanger 8.

Title: Fused carbonate fuel cell
Inventor: HADO KAZUHITO
IPC: H01M8/02
Filed: 1987-01-08
Abstract: PURPOSE:To stabilize the electrolyte holding performance for a long time by using at least two kinds of mixtures containing lithium aluminate among lithium aluminate, potassium titanate and lithium titanate for an electrolyte carrier. CONSTITUTION:The decrease in the electrolyte holding performance of an electrolyte carrier comprising at least two kinds of foreign materials containing lithium aluminate in a fused carbonate solution at high temperature is far small compared with the decrease with time in the electrolyte holding performance of an electrolyte carrier comprising a single material. By an arrangement that fine particles comprising two or more different kinds of materials are uniformly mixed, the growth of particles is prohibited because sintering between these foreign materials rarely occur resulting in the stable electrolyte holding performance for a long time. Here the constituent particles of the electrolyte carrier have a size of 10mum or less.

Abstract: PURPOSE:To eliminate the need of a window and a peeling process and to reduce the cost by laminating an andope multiple quantum well layer having exciton absorption and energy being lower than an energy gap of a substrate, on the substrate by a p-i-n structure. CONSTITUTION:On (n) type semiconductor substrate 41 having an energy band gap E2, an (n) layer 31 of a semiconductor, an (i) layer 21 containing a multiple quantum well in which energy E1 of an exciton absorption end is smaller than the energy gap E2 of the substrate 41, and a (p) layer 11 of a semiconductor are laminated successively to a p-i-n structure. Therefore, since the energy E1 of the exciton absorption end of the multiple quantum well layer 21 is lower than the energy band gap E2 of the substrate 41, an output light for passing through the p-i-n structure transmits through substrate 41. Accordingly, a window and a peeling process which are necessary up to the present becomes unnecessary, and the cost of a secondary array can be reduced.

The second condition is (Ib+Id-Ith(TL))/Ib-Ith(TL))>=R where R is the desired extinction ratio, and (Ib+Id-Ith(TL)/(Ib-Ith(TL) is an extinction ratio. The third condition is that the oscilation delay time which is determined by a threshold current Ith(TH) at the upper limit temperature within the applicable temperature range and the carrier life in a semiconductor laser becomes shorter than or equal to the desired oscillation delay time. By the above three conditions, the bias condition for minimizing the driving current can be determined, and excellent operation is realized.

Title: Filter
Inventor: IHARAKI EIJIROU
IPC: H03H17/00
Filed: 1981-01-14
Abstract: PURPOSE:To enhance the high-speed response and stability, by combining an analog filter and a digital filter. CONSTITUTION:For a filter to be provided to an AC input of a protection/control device of an electric power system, a digital filter has a high-speed response to the elimination of a low frequency component with an intrinsic speed of response secured for each type of filter and has the upper limit to use 1/2 sampling frequency. While for an analog filter, the elimination of a high frequency component is facilitated and the speed of response varies by the attenuation factor. For the filter of the AC input of a digital protection relay, an analog filter that cuts the frequency of >=1/2 sampling frequency of a digital filter is set previously to a digital filter. The digital filter cuts a low frequency component such as a drift component. Thus the merits of a digital filter and an analog filter can be obtained by combining these two filters.
