Title: Nuclear reactor shut down apparatus
Inventor: SEKIGUCHI MINEO
IPC: G21C7/14
Filed: 1993-02-10
Abstract: PURPOSE:To ensure safety of a nuclear reactor by composing an element, corre sponding to the extension pipe of a conventional control rod drive mechanism, of a wire thereby inserting a control rod quickly into the reactor core by taking advantage of the flexibility of the wire even when a guide pipe is bent due to earthquake. CONSTITUTION:Upon receiving an emergency stop signal for nuclear reactor, an electromagnet 34 is de-energized and a member 35 is released therefrom. Consequently, a spring 47 urged upward and compressed by a control rod 42 and an acceleration pipe 45 quickly drops an entire extension pipe 36 comprising a finger 41, a finger support 39, and a wire 37 coupled with a finger rod 38.

Title: Liquid state gasket injection device and seal structure
Inventor: KITADA TAIZO
IPC: F16J15/14
Filed: 1989-02-01
Abstract: PURPOSE:To prevent generation of a harmful influence by excessive suction with an injecting time shortened and an air reservoir prevented from being formed by setting a negative pressure pump, which returns a liquid-state gasket to a tank, smaller in the pump capacity than that of a pressure pump feeding out the liquid-state gasket. CONSTITUTION:In injection time, air in a seal material injection groove is pressed by a liquid-state gasket 10, injected from an injection port, and moved toward a discharge port while forcedly discharged by a negative pressure pump 15 connected to the discharge port. Accordingly, an injecting time is shortened by preventing air from being left in the seal material injection groove and forming an air reservoir while promoting injecting the liquid-state gasket 10. Further because an overflow of the liquid-state gasket 10 is returned to a tank 12 by the negative pressure pump 15 or the like, the liquid-state gasket 10 improves its yield rate, while because the negative pressure pump 15 uses a pump smaller in its capacity than that of a pressure pump 13, possibility of generation is prevented of a harmful influence by excessive suction of the negative pressure pump 15.

Title: Silver halide color photographic sensitive material having improved color reproducibility
Inventor: YAMADA YOSHITAKA
IPC: G03C7/30
Filed: 1987-02-05
Abstract: PURPOSE:To improve the graininess and the color reproducibility of the titled material, without reducing the sensitivity of the titled material, without reducing the sensitivity of the titled material by providing with a hydrophilic colloidal layer having nonphotosensitivity between silver halide emulsion layers having different color sensitivities, and by incorporating a DSR compd. in the colloidal layer. CONSTITUTION:The hydrophilic colloidal layer having the nonphotosensitive property is interposed between the silver halide emulsion layers having the different color sensitivities, and the colloidal layer contains a compd. (DSR compd.) capable of scavenging an oxidant by allowing to react with said oxidant of the developing agent or the compd. capable of releasing the precursor of said compd. Thus, for example, even in case that the excess oxidant of the developing agent contd. in a blue color sensitive layer diffuses to a green color sensitive layer adjacent to said layer, the diffusion is prevented by trapping the oxidant by allowing the DSR compd. to react with said oxidant, thereby prevented the deterioration of the graininess in the green color sensitive layer. While, as the SC component of the scavenger is the nondiffusive, the DSR compd. does not diffuse to the color sensitive layer adjacent to an intermediate layer from said layer, and does not almost induce a competing reaction of the oxidant of the developing agent with the coupler in the color sensitive layer whereby the sensitivity of the color sensitive layer does not reduce.

The voltage is increased in the case of P<O. The time required until the set voltage is attained is shortened, while the voltage increase is heretofore unconditionally stopped when the abnormal discharge arises.
