Abstract:
A magnetic element including: a composite magnetic member A containing a metallic magnetic powder in an amount of 50-70 vol. % and a thermosetting resin in an amount of 50-30 vol. %; a magnetic member B that is at least one selected from a ferrite sintered body and a pressed-powder magnetic body of a metallic magnetic powder; and a coil. The magnetic element is characterized in that a magnetic path determined by an arrangement of the coil passes the magnetic member A and the magnetic member B in series and the coil is embedded in the magnetic member A. The present invention also provides a method for manufacturing the magnetic element.
Abstract:
An additional MOS transistor receiving at its control electrode a signal complementary to that applied to control electrodes of MOS transistors is provided between a power supply node and a control electrode line formed by resistors having a significant resistance and interconnecting respective control electrodes of MOS transistors which are connected in parallel and each of which is connected between output signal line and power supply node. When MOS transistors are rendered non-conductive, the additional MOS transistor is rendered conductive. As a result, internal nodes are driven by an inverter and the additional MOS transistor to a power supply voltage, thereby turning off MOS transistors at the same timing. Consequently, through current in a semiconductor output circuit can be suppressed and an output signal has no ringing.
Abstract:
This invention concerns a magnetic recording medium which comprises a nonmagnetic support, a magnetic layer provided on one surface of the nonmagnetic support and a backcoat layer provided on the other surface of the nonmagnetic support, wherein the nonmagnetic support is provided with such physical properties as Young's moduluses in the longitudinal direction and the lateral direction thereof in the range of 1300-1600 kg/cm.sup.2, respectively, and a breaking elongation in the range of 3-10% and said magnetic recording medium is provided on the magnetic layer side thereof with a convex cupping the magnitude of which is in the range of 0.02-0.20 mm at a width of 3.8 mm. The magnetic recording medium, therefore, realizes perfect head touch even when the thickness of the nonmagnetic support and the thickness of the whole medium are small. Even when the magnetic recording medium is exposed to the mechanical influences and physical influences of aging, it suffers extremely small change in the form (such as, for example, the cupping value) and therefore conserves the head touch and other factors in highly satisfactory state. It suffers occurrence of dropout or head stain only sparingly.
Abstract:
An image reading device includes a planar light source having sufficiently even illumination to allow accurate shading correction to be performed regardless of the position in the auxiliary scanning direction. The image reading device includes a light source, a photoelectric conversion device, a movement device and a computer. The planar light source includes a rod-shaped light-emitting device and a light-guiding plate that receives light from the rod-shaped light-emitting device and emits light from a single surface. The rod-shaped light-emitting device is at least along one lengthwise side of the light-guiding plate. The photoelectric conversion device converts the image into an electrical image signal which is processed by the computer. The movement device moves the photoelectric conversion device in the auxiliary scanning direction, which is substantially perpendicular to the longer lengthwise side of the photoelectric conversion device and substantially perpendicular to the longer lengthwise side of the rod-shaped light-emitting device.

Abstract:
A semiconductor memory comprising a flip-flop circuit, a redundant memory cell row and column, a specific address detecting gate, a transistor, a sense amplifier and a data output buffer. The receipt of a supply potential causes the flip-flop circuit to generate previously stored output status representing the use or the nonuse of the redundant memory cell row and column. Upon detection of a specific address by the specific address detecting gate, the transistor effects a switching operation causing the output status generated by the flip-flop circuit to be output to the outside via the transistor, sense amplifier and data output buffer. This allows the use or the nonuse of the redundant bits to be verified efficiently.

A process for producing a multilayer polytetrafluoroethylene porous membrane comprising at least two layers having different average pore diameters is disclosed, the process comprising the steps of: filling the inside of a cylinder of an extruding mold distinctively with at least two kinds of polytetrafluoroethylene fine powders with each of which a liquid lubricant has been mixed; subsequently paste-extruding the powders to obtain a multilayer extrudate, which is then optionally rolled; and then stretching the extrudate or the rolled extrudate at least monoaxially after the liquid lubricant is removed therefrom or without removing the liquid lubricant.
