A fuel injection valve coupled to a common rail is provided. When fuel injection is carried out, the fuel pressure in the fuel injection valve pulsates. An interval between a pilot injection and a main injection is set so that the main injection is carried out at a zero gradient timing as a timing when the gradient of the fuel pressure in the fuel injection valve after the pilot injection is approximately equal to zero. Owing to a fuel injection control apparatus and a fuel injection control method for an internal combustion engine that perform the above-mentioned control, the fuel injection amount for the subsequent fuel injection following the preceding fuel injection can be reliably held equal to a normal amount.

The present invention provides a bioassay system, for detection of hazardous chemical substances, natural toxic substances in the environment and unknown toxic compounds, with high sensitivity, simplicity and speed. The invention provides cells and a method of using the cells for use in the bioassay system. The cell provided by the invention contains a heat shock factor binding DNA sequence and a transcriptional regulatory sequence necessary on an occasion of stress induction as a transcriptional regulatory factor binding site. The cell also possesses a reporter gene under the control of the promoter. The reporter gene is connected, on the downstream side, to the SV40pA signal without any intervening intron.

The invention relates to a fabric used for preparing a base member of a trim member. This fabric is prepared by heating a mixture of a vegetable stiff fiber and a thermoplastic fiber. With this heating, the thermoplastic fiber becomes soft, and thus the vegetable stiff fiber and the thermoplastic fiber are united together. Examples of the vegetable stiff fiber are hemp fiber, coconut fiber and bamboo fiber. An example of the thermoplastic fiber is a composite fiber made of polyethylene and polypropylene. The fabric is superior in strength and workability and becomes advantageously low in heating temperature for molding the fabric.

There is disclosed an excrement treatment for small animals made up of small pieces containing bentonite and, if desired, wood powder or paper powder being formed in a shape of thin flat plates or waved plates, wherein the thickness of the small pieces of the excrement treatment is from 0.1 to 2 mm, and the average aspect ratio of the treatment is from 3 to 50; and a method of manufacturing the treatment. According to the treatment, making an excrement-incorporated mass small and solid, enabling a small amount of the litter to be discarded, and permitting the toilet for small animals to be made compact, can be done.

A vented filter cigarette with a filter having a fiber filter material and a plug wrap paper wrapping the fiber filter material, a tobacco rod, and tipping paper having a plurality of pores and connecting the filter and the tobacco rod. An embossment is formed in a region of the plug wrap paper corresponding to the pores of the tipping paper. The embossment creates a slight gap between the tipping paper and the circumference of the filter around the pores, with the result that the tightness between the tipping paper and the circumference of the filter is loosened, the filter ventilation is increased, and the variation in the filter ventilation is decreased.

摘要:
An electrophotographic photosensitive member is constituted by an electroconductive support, and an intermediate layer and a photosensitive layer disposed in this order on the support. The intermediate layer comprises a reaction product of a mixture including a polyol compound [I], a polyol compound [II] having an OH equivalent different from that of the polyol compound [I] and a polyisocyanate compound. The polyol compound [I] is a polyether polyol compound having an OH equivalent of at least 500 and 2-60 OH groups per molecule; and the polyol compound [II] is a polyol compound having an OH equivalent of at most 300. The photosensitive member shows stable electrophotographic performances over wide environmental conditions from low temperature--low humidity to high temperature high humidity due to the intermediate layer.
