Abstract: A nonvolatile memory includes circuits each having first control transistors, memory transistors, second control transistors and memory transistors repeatedly connected in series in sequence. Inversion layers are formed in the direction intersecting the serial direction with turning on of the control transistors. A selection circuit selects a connection of the inversion layer placed under the first control transistor and its corresponding read/write circuit. The control transistors placed on both sides adjacent to the memory transistor are turned on to perform reading. The first control transistors placed on both sides of the second control transistor as viewed from side to side are turned on to perform writing into the other of the right and left memory transistors via one of the right and left memory transistors. The selection circuit connects the read/write circuit and the inversion layer in such a manner that the same read/write circuit is used in reading and writing for the same memory transistor.

Abstract: A method for quantitating a specific component in lipoproteins contained in a biological sample, for example, HDL (high-density lipoprotein), LDL (low-density lipoprotein) or VLDL (very low-density lipoprotein) by using a commonly employed automatic analyzer without centrifuging or making the reaction liquor cloudy due to complexes or aggregates. Namely, a controlling means, whereby an enzyme reaction can be carried out exclusively for the target component, is introduced into a method for enzymatically assaying a component in a specific lipoprotein fraction in the serum, thereby specifically assaying the component.

Abstract: The object of the present invention is to provide a method for more accurately assaying the enzyme activities of mCK isozymes and a method for separately assaying the enzyme activities of CK isozymes by separately assaying the enzyme activities of ubiquitous mCK (umCK) and sarcomeric mCK (smCK). The above object is attained by an assay using an antibody that specifically recognizes umCK protein. In addition, other anti-mCK antibodies (e.g., anti-smCK antibody) and/or anti-human CK-M-inhibiting antibody can also be used. The above antibody is a polyclonal antibody or a monoclonal antibody. As a result of these antibodies, a monoclonal antibody (U1-1881) that is capable of specifically recognizing human umCK and is produced by a hybridoma having a deposition number of FERM BP-8342 is provided.

Abstract: At least not less than one capacitor formation trench providing an uneven surface is formed on the surface of a capacitor formation region. Thus, the surface area of a capacitor is increased, which enables improvement of the capacitance of the capacitor per unit area. Further, by forming the capacitor formation trench and an element formation trench that are formed in the surface of the semiconductor substrate by the same step, it is possible to simplify the manufacturing process. Whereas, a dielectric film of the capacitor in the capacitor formation region and a high-voltage gate insulating film in a MISFET formation region are formed by the same step; alternatively, the dielectric film of the capacitor in the capacitor formation region and a memory gate interlayer film between a polysilicon layer and a polysilicon layer in the memory cell formation region are formed by the same step.

Abstract: There is provided a method for a selective assay of component, particularly cholesterol, in very low-density lipoprotein (VLDL) which is one of serum lipoproteins. In the assay, an enzymatic reaction of lipoprotein lipase (LPL) or cholesterol esterase (CE) which well reacts with high-density lipoprotein (HDL) and VLDL is carried out at least in the presence of calixarene or a salt thereof. It is also carried out in the presence of one or more substance(s) selected from albumin and basic amino acids in addition to calixarene or a salt thereof.

Abstract: The conventional multi-port cache memory, which is formed by using multi-port cells, is excellent in its operating speed. However, the integration area of the constituent multi-port cells is increased in proportion to the square of the number of ports. Thus, if it is intended to decrease the cache miss probability by increasing the storage capacity, the chip size is increased correspondingly, which increases the manufacturing cost. On the other hand, the multi-port cache memory of the present invention is formed by using, as constituents, one-port cell blocks adapted for a large storage capacity, making it possible to easily provide a multi-port cache memory of a large storage capacity and reduced integration area, which has a large random access bandwidth, is capable of parallel access from a plurality of ports, and is adapted for use in advanced microprocessors having a small cache miss probability.

Abstract: A store apparatus determines the number of points given to a customer who has purchased a commodity using a customer apparatus via the Internet, in which the number of points are determined based on a roulette game. Since the point value given to the customer who purchases the commodity is determined by the roulette game regardless of the cost of the commodity purchased, the specific time period when purchased or the specific commodity purchased, it is possible to keep the willingness of the customer to purchase commodities and to direct that willingness to all commodities. In addition, since the customer can acquire higher points than the points usually given depending on the result of the roulette game, it is possible to further rouse the willingness of the customer to purchase commodities. Further, the customer is capable of shopping with more fun.

Abstract: A method for assaying biological specimens for substances contained in the components of each specimen by the use of one or more kinds of calixarenes; and a reagent comprising one or more kinds of calixarenes. The method utilizes complexes formed by calixarenes and the components of biological specimens, and makes it possible to assay biological specimens for substances contained in the components of each specimen, for example, for cholesterol contained in high-density lipoprotein (HDL), without preliminary separation from the other components of the biological specimen. The method can be conducted by easy and simple operations and lessen measurement errors or problems caused by man, and permits continuous measurement with general-purpose automatic analyzing apparatuses and multi-channel measurement together with other test items.
