A semiconductor memory device with a write control circuit free from error which may be induced during readout operation by noise on power line, or the like, is disclosed. The memory device comprises a write circuit for writing data to a selected memory cell, and a read circuit for reading data from the selected memory cell, a first control circuit for enabling the write circuit in response to a write enable signal, and a second control circuit for enabling the read circuit in response to a read enable signal. The first control circuit additionally receives the read enable signal and enable the write circuit only when the write enable signal is present and the read enable signal is not present.

In a multi-layer blow molded container having a joint portion at least in the bottom portion thereof, barrier characteristics to gases such as oxygen and water vapor and liquids such as water, solvents, aqueous ammonia and salt water and interlaminar strength characteristics such as interlaminar adhesion strength, peel strength and impact strength in the content-filled state can be highly improved by blow molding a parison of a laminate structure of two or more polymer layers in which the polymer composition is different with respect to the thickness direction of the container wall but substantially identical with respect to the plane direction and each of the polymer layers is continuous with respect to the plane direction, in such a manner that a tapered projection protruding outwardly in the thickness direction of the container wall is formed in the joint portion so that each of the polymer layers is substantially continuous in this joint portion. This improved container can easily be prepared according to the customary blow molding technique by using a pair of split molds having such a configuration that a tapered concave groove is formed in the section pinching off the parison when the molds are registered with each other.
摘要:
A battery containing body having a flat shape that can be inserted to and removed from a power storage device, wherein a handle is provided at an end portion on a front side in a direction of insertion, and at least at a lower end portion from among the lower end portion and an upper end portion when the battery containing body is inserted upright, a recess portion for supporting the lower end portion is provided.
摘要:
The present invention provides a method and an index capable of less-invasively determining myocardial ischemia such as ischemic heart disease or restenosis after percutaneous coronary intervention. The present invention also provides an index that allows the cardiovascular disease other than heart failure to be determined even from a blood sample showing a BNP value from which the cardiovascular disease other than heart failure cannot be determined by a conventional method. A method for determining myocardial ischemia comprising subjecting a blood sample which is derived from a test subject and which contains a BNP molecular group containing at least two selected from the group consisting of BNP 1-32 molecule, BNP 3-32 molecule, BNP 4-32 molecule, BNP 5-32 molecule, and a molecule having a mass number larger than that of BNP 5-32 molecule by 16 Da to a detection process capable of distinguishing and quantifying the individual BNP molecules different in mass number to detect the BNP molecular group, wherein myocardial ischemia in the test subject is determined using, as an index, a ratio between a detected intensity of at least one molecule selected from the BNP molecular group and a detected intensity of at least one other molecule selected from the BNP molecular group.
