    摘要： A semiconductor memory device includes a plurality of sense amplifiers for amplifying current changes which occur in corresponding bit line pairs in accordance with binary signals stored in activated memory cells. Each of the sense amplifiers includes first and second current mirror circuits for generating currents of the magnitudes respectively corresponding to currents flowing through a corresponding bit line pair, a storing circuit, responsive to a signal selecting a memory cell, for storing the currents generated by the first and second current mirror circuits before activation of the memory cell, or a difference between these currents, and a current supplying circuit, responsive to activation of the memory cell and based on the amount stored in the storing circuit, for supplying, to the first and second current mirror circuits, currents having a predetermined relationship with the currents having been generated by the first and second current mirror circuits before activation of the memory cell. A current change corresponding to data stored in the selected memory cell and not affected by an offset occurs in a connection node between the first current mirror circuit and the current supplying circuit, or a connection node between the second current mirror circuit and the current supplying circuit.

    摘要： Disclosed herein is a lid guide structure for a sun roof device. The lid guide structure comprises a first elongate member, and second and third elongate members extending in parallel from longitudinal ends of the first elongate member. Each of the second and third elongate members includes a longitudinally extending gutter portion which is defined between outboard and inboard walls. Mutually facing surfaces of the outboard and inboard walls are each formed at a major flat part thereof with a longitudinally extending channel leaving a longitudinally extending ridge at the upper end of each wall. Each of the longitudinally extending channels is defined by two inclined surfaces, one surface close to the longitudinally extending ridge and one remote from the ridge.

    摘要： A kit for the administration of a radiopharmaceutical liquid composition has been developed, which includes a radiation-shielding injector accompanied with a syringe-type vial having a gasket therein, a seal cap and a plunger to be engaged with the gasket. The injector is made of a radiation-shielding tubular metal body covered with a plastic material having an exit at the bottom, the body being further provided with a lead glass window on its curved surface, a packing engaging the inside surface at one end of the body and a pair of wings having skid-proof ridges formed on at least one surface thereof, the wings being located at one end of the body. The body is so designed as to be shorter than the tubular portion of the syringe-type vial to be inserted therein, whereby the rear portion of the vial protrudes a little from the tubular body when the same is inserted into the body.
