  • Publication number: 20190279666
    Abstract: A spin transfer torque (STT) device is formed on an electrically conductive substrate and includes a ferromagnetic free layer near the substrate, a ferromagnetic polarizing layer and a nonmagnetic spacer layer between the free layer and the polarizing layer. A multilayer structure is located between the substrate and the free layer. The multilayer structure includes a metal or metal alloy seed layer for the free layer and an intermediate oxide layer below and in contact with the seed layer. The intermediate oxide layer reflects spin current from the free layer and thus reduces undesirable damping of the oscillation of the free layer's magnetization by the seed layer.

  • Publication number: 20090172764
    Abstract: In a broadcast receiving device, a broadcast signal of a data broadcast program that is tuned in to by a tuner is demodulated into a transport stream by a demodulator, and a data broadcast content is acquired by an information acquisition unit from the demodulated transport stream. The acquired data broadcast content is stored in a storage device, and a data broadcast screen based on the stored data broadcast content is presented by an information presentation unit. When a reception state is a poor state, a presentation state of the data broadcast screen is held by the information presentation unit. When the reception state changes from the poor state to a good state and the data broadcast programs received in the good states before and after the poor state are the same, the presentation of the data broadcast screen based on the stored data broadcast content is restarted by the information presentation unit.

  • Patent number: 5635996
    Abstract: A memory device for channel selection in a television receiver comprises a nonvolatile memory for storing at least one set of channel data and channel attendant data, and a RAM having a channel data storing part which accesses and stores all channel data stored in the nonvolatile memory. When a read tuning command is given, the nonvolatile memory is accessed in order to search addresses of the channel attendant data if a specified channel exists in the RAM. When no specified channel data exists in the RAM, the nonvolatile memory is not accessed.

  • Patent number: 5483685
    Abstract: In a receiver having a channel selection apparatus which is capable of receiving channels of the number of three digits, when the receiver is used in a zone having channels of the number of two digits or the number of one digit, a reference counting value corresponding to digits of the number of the channels is set in a counter. Counting operation of the counter is changed by changing the reference counting value and a channel selection time of a channel in the number of two digits or the number of one digit is reduced.

  • Patent number: 5408273
    Abstract: A muting circuit for a television receiving set comprises a mute-judging part, a mute key input, an acoustic output circuit, a caption-judging part, and a caption key input. The mute-judging partenters a mute ON and a mute OFF state alternately every time it receives a mute key input signal. The acoustic output circuit reduces the sound output level to zero decibels at the mute ON state, and restores the sound output at the mute OFF state. The caption-judging part enters a caption ON state and caption OFF state alternately every time it receives a caption key input signal while it enters a caption ON state if the mute-judging part enters a mute ON state. Thus, in the mute ON stated the closed caption is displayed on the screen.
