Abstract: Provided is a structure having a perpendicular magnetization film which is an (Mn1-xGax)4N1-y (0<x?0.5, 0<y<1) thin film having a nitrogen-deficient composition which is formed by controlling and introducing nitrogen N into an MnGa alloy or a thin film containing at least one of Ge, Zn, Sb, Ni, Ag, Sn, Pt, and Rh, instead of Ga. The perpendicular magnetization film exhibits a Curie temperature sufficiently higher than room temperature, has saturation magnetization smaller than that of existing materials, and is capable of being fabricated as a very flat film.

Abstract: An integrated circuit device for testing is disclosed. The device includes a plurality of internal circuits for generating a plurality of internal signals, the internal signals used for addressing storage locations and for controlling internal operations, a first selection circuit for receiving the internal circuits in response to selection signals corresponding to test information signals, a second selection circuit for receiving output signals from the first selection circuit and output signals from a sense amplifier, and for opening an alternative one of transfer paths of the internal signals and the output signals in response to the selection signals, and a data output buffer for transferring output signals from the second selection signals to an outside of the device through data input/output pads.
Abstract: The invention relates to systems for receiving a digital radio signal and, more particularly, to receivers of radio signals, coded with a pseudo-noise sequence, which are used in global positioning system GPS (USA) and GLONASS (Russia), allowing a compensation effect for the narrow-band interference by using a device, controlled by the processor, with an automatic gain control, multilevel analog-to-digital converter, and additional correlation channel for detection of sinusoidal interference consisting of the digital generator having quadrature mixers and accumulators. Information from output of the of accumulators is read by a processor, in which is detected the presence (or absence) of interference, and the amplitude is evaluated. Therefore, the processor generates control signal directing amplification in the device using an automatic gain control.
Abstract: The invention relates to the design of radio electronic devices and, more particularly, to antenna-and-feeder facilities to be used in portable (pocket) receiver-indicators of the GPS and GLONASS satellite radio navigation systems (SRNS) using the quadrifilar antennas for reception of signals. The claimed portable receiver-indicator comprises a body, made in the form of a parallelepiped and a quadrifilar antenna made as a parallelepiped and connected to the body with a possibility of rotation, said antenna having a connecting cable. The design enables convenient use of the receiver-indicator while providing its small size and minimum screening effect of the body in the operating position.
