Abstract: There is provided a sheet discharging apparatus and an image forming apparatus, in which even a curled sheet can properly be discharged to and stacked on a sheet stacking portion. A projection is provided in a central portion in a width direction of a tailing end regulating portion while projected toward an upstream side in a sheet discharge direction. The tailing end regulating portion regulates a tailing end position of the sheet stacked on the sheet stacking portion. The tailing end position of the sheet discharged to the sheet stacking portion is supported by the projection, and the both end portions in the width direction of the sheet are pushed down below an upper surface of the projection by pressing portions at both ends of a full load detecting flag, thereby bending the sheet.

Abstract: A pressure sensor is composed of a pressure housing having a pressure chamber inside and a pressure sensitive element arranged in the pressure chamber, and a joint housing having a fluid passage for leading fluid into the pressure housing, wherein the pressure housing and the joint housing are jointed by brazing with an insulating member interposed at a joint section therebetween. A stress relieving member is interposed at least either between the metal housing and the insulating member or between the joint housing and the insulating member, so that the insulating member can be relieved of a stress which is caused by the braze jointing to act on the insulating member.

Abstract: In a pressure sensor which has a metal housing 12 containing a sensor chip 11 and a joint housing 14 and in which an insulating member 15 is arranged to electrically insulate both of the metal housing 12 and the joint housing 14 from each other, the metal housing 12 is connected to a stable potential such as, for example, a sensor power supply or a sensor ground. Thus, there can be solved a problem that the detection signal is liable to be influenced by electric noise from outside where a signal line of the pressure sensor and the sensor housing are electrically suspended or unfixed.

Abstract: An object of the present inventions is to overcome a problem that the presence of a metal film, which is opaque to a visible light, between a lower layer alignment mark and a photoresist prevents the detection of the lower layer alignment mark, to make the pattern formation difficult. In the present inventions, an insulating film is placed beneath the alignment mark in structure; an alignment mark consisting of said multi-layered film comprising an alignment mark layer and the insulating film, which constitutes a stepped part with an increased difference in level, is first formed, inside a mark hole, in a manner of self-alignment; and then the metal film which is the very cause of the above problem is formed thereon. Since the metal film itself has a stepped shape corresponding to the alignment mark, alignment can be made with great accuracy.

Abstract: A core having a coil wound thereon is fixed to a base at the bottom. The base is fixed to a case made of synthetic resin by insert molding. A diaphragm is fixed to the case in circumference, and also a magnetic flux guide member is fixed to the case in circumference. Since the diaphragm and the magnetic flux guide member is commonly fixed to the case, no variation in the distance between the diaphragm and the magnetic flux guide member would occur for every product. Further, a gap L is formed between the magnet and the magnetic flux guide member, and an air hole is formed in the magnetic flux guide member. This improves the passage of air and reduces air dumper effect without modifying the magnet in shape.

Abstract: There is provided a method of reducing biofilm formation by biofilm-forming bacterial strains such as E. coli, Salmonella, Klebsiella, or a related gamma proteobacteria. CsrA activity levels in the cell may be modulated to impact biofilm formation and glycogen metabolism. CsrA levels may be modulated by modulating the expression of csrB RNA and UvrY and BarA gene products. By increasing levels of CsrB, BarA or SdiA in a bacterial cell or increasing the rate of UvrY phosphorylation, one can increase the levels of active UvrY in the strain. There is also provided a modulator of CsrA activity in a bacteria comprising a nucleotide sequence containing the sequence element CAGGAUG.
