摘要:
Dominant negative mutants of mammalian IRS-1 proteins and therapeutic compositions containing such mutants. Also featured are methods of using the dominant negative mutants to inhibit tyrosyl phosphorylation of endogenous IRS-1 in mammalian cells and methods of treating a mammalian malignancy in which tyrosyl phosphorylation of endogenous IRS-1 plays a causative role.
摘要:
A rotary head in which the tape running load is decreased by setting the tape path cylindrical surface of an upper drum (12) in a range of winding of a tape (31) at an inner side relative to the tape path cylindrical surface of a lower drum (11). Alternatively, the tape path cylindrical surface of an inner drum (13) in a range of winding of the tape (31) is positioned at an outer side relative to the tape path cylindrical surface of the upper or lower drum.
摘要:
Disclosed are a photosensitive resin composition for printing plate materials, which comprise a polymer having an ionic group and a polymerizable group in the side chain, and a printing plate material as formed by applying the composition onto a support. The hardness of the photosensitive layer of the composition is hardly influenced by temperature and water, and the layer, after having been developed, has good resistance to aqueous ink.
摘要:
A recording body is used which includes a base material and a recording material having characteristics of the wettability change by heating, the recording material being coated on the base material so as to form a recording surface. The image forming method includes the steps of a) heating the recording surface of the recording body in liquid; and b) partially heating the recording surface in air so as to form a latent image.
摘要:
An artificially patinated copper plate in which a copper sulfide layer 2 is formed on the surface of a copper base plate 1 by sulfiding for coating the same, and the copper sulfide layer 2 having an artificially patinated layer 3 is formed distributed and bonded thereon by spraying a resin solution mixed with basic copper carbonate constituting the main component of natural patina. The percentage of the area occupied by the artificially patinated layer 3 on the copper sulfide layer 2 is most preferably 25% to 80% and the thickness of the copper sulfide layer 2 is most preferably 0.1 to 0.5 .mu.m.
摘要:
Normal column selection signal switching device (20) is provided to switch a signal outputted from normal column selection signal generating device (19) in response to a test-mode signal (TMC1). Even if the normal column selection signal generating device (19) outputs a signal to disable a normal column decoder (3), the normal column selection signal switching device (20) switches the signal to enable the normal column decoder (3) to operate in the test operation. Having this configuration, a semiconductor memory device enables writing of data into all the normal memory cells even after some of the normal memory cells are replaced by spare memory cells.
摘要:
A mounting structure for an integrated circuit device comprises a first substrate, a second substrate and an insulator. The first substrate contains conductive wiring electrically connected to the integrated circuit device. The first substrate is mounted on the second substrate which have a ground pattern. The insulator is provided between the conductive wiring and the ground pattern.
摘要:
A protection circuit device for protecting a secondary battery from an overcharge and/or an overdischarge has first and second terminals, across which a charger and a load are alternatively connectable. A first switch and/or a second switch may be provided in series with the secondary battery between the first and second terminals. In a charging operation mode, the second switch is kept conductive. A charging operation is performed with the first switch made conductive. When the battery is overcharged for some reasons, the first switch is turned off. Upon connection of a load across the first and second terminals, the first switch is restored to a conductive state for a discharging operation which releases the battery from an overdischarge state. In a discharging operation mode, the first switch is kept conductive. A discharge operation is performed with the second switch made conductive. When the battery is overdischarged, the second switch is caused to remain conductive even after commencement of the overdischarge, so that the battery can continue the discharge operation if the temporary overdischarge does not last longer than the predetermined period of time.
