  • Patent number: 4267583
    Abstract: A memory device having a test function for detecting abnormal memory cells having low hold ability is disclosed. The memory device characteristically comprises a first write control circuit which operates in a normal write mode and a second write control circuit which operates in a pseudo write mode to supply a pseudo write signal lower than a threshold value at which the state or content of the normal memory cell is changed or inverted, to the memory cell to be tested. In such a pseudo write mode, the state of the normal memory cell remains unchanged, but if the tested memory cell is abnormal, its state is changed. After the pseudo write mode, the tested memory cell can be detected to be normal or abnormal by reading out the content of the tested memory cell.

  • Patent number: 4233635
    Abstract: A high voltage limiting circuit for a television receiver employs a negative pulse sample from a tertiary winding on a flyback transformer as a measure of high voltage. When the amplitude of the negative pulse sample exceeds a predetermined value, indicating excessive high voltage, a limiting circuit applies a voltage to an automatic frequency control input of a horizontal oscillator to increase the frequency of the horizontal oscillator. The increased frequency limits further increase in high voltage.

  • Patent number: 4205805
    Abstract: An apparatus is disclosed for automatically starting the winding of a web or strip of paper material onto a rotating take-up spool. Triangular-shaped guide members projecting from opposing sides of the take-up spool guide the free end of the moving web to a position between oppositely-aligned guide members and the hub of the take-up spool allowing the free end of the web to be gripped by other guide members positioned downstream of the engaged guide members for winding the web onto the hub of the take-up spool. The oppositely-aligned guide members have a web supporting surface which is inclined towards the hub and are spaced slightly less than the width of the web allowing the free end of the web to slide to a position beneath the guide members in which the web is gripped by adjacent guide members as the spool rotates resulting in the web being wound onto the spool.

  • Patent number: 4116881
    Abstract: In removing nitrogen oxide from a gas containing it, the gas is passed through a region where at least one of calcium sulfate and calcium hydroxide coexists with powerful oxidation agents such as sodium chlorite, potassium permanganate, etc. thereby removing the nitrogen oxide, mainly nitrogen monoxide, from the gas. This method is very effective in purifying exhaust gases resulting from burning operations, since 80 to 90% or more of the nitrogen oxide contained in the exhaust gases is nitrogen monoxide. In addition, this method is also effective in purifying indoor air.
