Patent number: 5844868Abstract: A digital-analog shared circuit in dual mode radio equipment, which shares a local oscillator in a digital mode and analog mode. A first frequency synthesizer generates a first and a second local oscillation frequency in a digital and an analog receiving mode, respectively, in response to a control signal from a switching control. In the digital receiving mode, a quadrature demodulater including a first and a second demodulator in a demodulator section is enabled, and carries out quadrature detection of a received signal fed from an RF stage, thereby supplying the detected signal to a baseband signal processor stage. In the analog receiving mode, a buffer to which the second local oscillation frequency is supplied is enabled to deliver the second local oscillation frequency to the analog IF stage. A second frequency synthesizer generates a third local oscillation frequency in a digital transmitting mode and a fourth local oscillation frequency in an analog transmitting mode.Type: GrantFiled: March 26, 1997Date of Patent: December 1, 1998Assignee: Oki Electric Industry Co., Ltd.Inventors: Chusei Takahashi, Tsutomu Katsuyama

Patent number: 5844755Abstract: Information is recorded by applying weak and strong magnetic fields to a giant magnetoresistive medium having a pair of ferromagnetic layers, a nonmagnetic interlayer, and an antiferromagnetic layer. The medium preferably has a magnesium-oxide base layer, and may also have an electrode layer. The weak magnetic field magnetizes the ferromagnetic layers in the antiparallel state. The strong magnetic field magnetizes the ferromagnetic layers in the parallel state, which has lower electrical resistance than the antiparallel state. The recorded information is reproduced by detecting the electrical resistance of the medium, either between two electrodes contacting the surface of the medium, or between the electrode layer in the medium and an electrode contacting the surface of the medium.Type: GrantFiled: December 8, 1995Date of Patent: December 1, 1998Assignee: Oki Electric Industry Co., Ltd.Inventors: Haruki Yamane, Yoshinori Maeno, Masanobu Kobayashi

Patent number: 5842117Abstract: An antenna system for small basic transmitter-receiver stations of a communications system for mobile radio operators, with at least one transmission channel and one reception channel which operate on separate frequencies, with at least two antennas which are embodied for redundant reception (reception diversity). Each antenna is used as a transmission antenna for at least one channel. The transmitting operation is carried out without redundancy so that each antenna is fed by a different transmission channel, and the reception diversity is realized so that at least one antenna is set to receive a channel which is associated with the transmission channel of another antenna. The antenna system can be employed in mobile radio networks, in particular the D- net and the E-net. Advantages of the antenna system are low cost, low transmission loss, and high channel flexibility, and above all, the prevention of system interferences as a result of intermodulation products.Type: GrantFiled: April 9, 1996Date of Patent: November 24, 1998Assignee: Ant Nachrichtentechnick GmbHInventors: Uwe Rosenberg, Dieter Cluse

Patent number: 5841853Abstract: A telephone apparatus can receive information about a third party sent from a telephone exchange with a call waiting service when a call is issued from the third party during a conversation using the telephone apparatus. Upon issuance of the call from the third party during the conversation over the telephone apparatus, the exchange sends out an alert signal, in response to which the telephone apparatus sends back an acknowledge signal. The telephone apparatus also mutes a speech transmitter circuit in order to protect calling party information such as a telephone number sent from the exchange in succession from being destroyed by a speech signal. The calling party information sent from the exchange can be received without fail and can subsequently be displayed.Type: GrantFiled: August 16, 1996Date of Patent: November 24, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Koji Yamanishi, Takako Ito, Kouichi Kamimoto

Patent number: 5841400Abstract: A desired signal is received at first and second antennas. Output signals of the first and second antennas are orthogonal-detected by first and second signal conversion circuits and thereby converted into first and second baseband signals. A complex conjugation circuit generates a complex conjugation signal by calculating a complex conjugation of the second baseband signal. The first baseband signal and the complex conjugation signal are multiplied by a multiplier. A direction estimation circuit estimates a direction of the desired signal by effecting an inverse tangent calculation and an inverse cosine calculation on an output signal of the multiplier.Type: GrantFiled: October 7, 1997Date of Patent: November 24, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Katsuhiko Hiramatsu

Patent number: 5842013Abstract: Very large amounts of data may be handled by the user interface of computers. The main processor is thus permanently overloaded, so that the computing power available for the actual application is sharply reduced in a manner that cannot be predicted without limiting the user requests. A new computer architecture is disclosed which allows a higher and more exactly predictable computing power to be achieved. In order to make the rest of the system independent from the user interface, the computer is subdivided in such a way that a first module (part 1) takes over the display and operation tasks of the user interface, a second module (part 2) takes over the processing of the application programs without their user interface, and a third module (part 3) takes over the remaining functional units. All modules have their own internal data paths. An interface between the first and second modules support the exchange of messages and data without affecting the independent processes in the first and second modules.Type: GrantFiled: February 8, 1996Date of Patent: November 24, 1998Inventor: Martin Kopp
