Abstract: A nonvolatile semiconductor storage device storing plural data bits in one memory cell by assigning multivalued data having a higher-order bit selected from one of a pair of data in a first unit and a lower-order bit selected from the other of the pair of data. In a first write operation processing data in the first unit, logic of one of the higher-order and the lower-order bit is fixed, and two multivalued data that maximize the difference between the threshold voltages are assigned, thereby storing one bit of input data in the memory cell in a pseudo binary state. In a second write operation processing data in a second unit larger than the first unit, plural input data bits in a multivalued state and parity data for error correction in the second unit are stored in the memory cell.

Abstract: The present invention provides a rice catalase B promoter for inducing expression specifically in at least one site of roots and stem apices. By using this promoter, it is possible to synthesize a resistance substance against nematodes or soil pathogens in roots; synthesize a substance promoting the development of roots in the roots; produce a gene recombinant plant in which expression of a selective marker in the redifferentiated plant body is limited to roots when the plant is young, so as to suppress the expression when the plant is matured; or the like. Further, the capability of expression in stem apices can be used to develop a technique for suppress gene expression in vigorously proliferating cells.

Abstract: The present invention relates to a method for inferring a plant organ, in which a certain gene is to be expressed, using a part of a base sequence, a method for searching for a gene which is to be expressed at a desired site, and a composition, kit, system and program for carrying out these methods. The present invention also relates to a method for inferring a plant organ, in which a plant gene is to be expressed, based on information about the presence or absence of a base sequence which is highly similar to a transposable element in the vicinity of a protein coding region of a plant gene.

Abstract: An operating frequency setting unit outputs an ultrasonic emitting command to a variable oscillator circuit in an operating frequency setting mode to cause a detector to emit an ultrasonic wave a plurality of times while varying the frequency thereof. At this time, emission or reflected waveform data are inputted via a band pass filter to detect a resonance frequency of a system including the piezoelectric element of the detector and an LPG tank on the basis of the difference between attenuation characteristics of waveforms. The detected resonance frequency is registered in a memory part as an operating frequency. Thus, it is possible to provide a general purpose ultrasonic sensor usable for any one of a plurality of vessels having any wall thickness and material when an object is detected while the detector is mounted on the outside face of a vessel.

Abstract: A material for optical recording by utilizing the photochemical hole burning is disclosed. The optical recording material is a composition comprising a watersoluble deuterated polymer as a host component and a water-soluble organic pigment dispersed in the host component as a guest component. By virtue of the deuteration of the host component, the tunnel effect of the hydrogen atoms in the host component is prevented, so that the hole width is narrowed. Thus, the wavelength multiplicity is increased.

Either an organic polymer or an inorganic polymer is used as the polymer. From the viewpoint of the recording stability, a water-soluble polymer such as polyvinyl alcohol or sodium polystyrene sulfonate is preferred as the organic polymer.
