Title: Direct spread receiver and direct spread transmitter
Inventor: WADA YOSHIO
IPC: H04B1/707
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a direct spread receiving device which permits reducing the interfering components of mutual multi-paths of direct spread signals simultaneously transmitted from a plurality of system transmission antennas for reducing the influence of Rayleight fading. SOLUTION: In this direct spread receiving device, an antenna having a path Px whose power is the maximum is selected as an antenna X according to the impulse responses of reception signals from antennas A and B whose spreading codes are different from each other. An interference canceller 5 virtually generates the direct spread reception signals of paths other than the path Px whose power is the maximum from the antenna X and the direct spread reception signals of the plural paths from the antenna other than the antenna X as an inference replica based on initial reception data, and removes the virtually generated signals from the received direct spread signal, and outputs the inverse spread signal of a user channel C of the path Px whose power is the maximum.

Title: Discharge lamp lighting device
Inventor: KONO TADAHIRO
IPC: H05B41/24
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To surely operate a no-load detection circuit when input power source is turned on in an no-load state and when a discharge lamp is incompletely mounted and surely perform an intermittent oscillating operation, when emission- less of the discharge lamp is detected by adding a means for varying a detection voltage to the no-load detection circuit and changing detected voltage for a prescribed period. SOLUTION: A no-load detection circuit is provided with a varying means of detected voltage Vc1, and detected voltage is made to be lowered at least for a recharge period. As a result, because a time Tc1 which is the time for voltage Vc1 of a capacitor C1 to reach a reference voltage Vk becomes Tc1<Vk, the no-load detection circuit becomes normal operation and is decided as being at no-load, even if a time constant with resistance R1 and the capacitor c1 is not set to a smaller, oscillation will not start. When discharge lamp load exists, since a reducing degree of detected voltage Vc1 needs to be designed carefully, because Vc1>Vk is required when the precharge period is finished.

Abstract: PROBLEM TO BE SOLVED: To provide an Sm-Fe-N magnetic powder manufacturing method capable of manufacturing an Sm-Fe-N magnetic powder at a drastically low cost as compared with the conventional manufacturing method and capable of inexpensively providing an anisotropic bonded Sm-Fe-N magnet. SOLUTION: An Sm powder and an Fe powder are formed into a melt 20. The melt 20 is rapidly solidified by being brought into contact with a spinning cooling roll 16, by which a ribbon-shaped material 18 composed of Sm2Fe17 is formed. When the cooling velocity at this time is set at a value within a proper range, the (116) plane of Sm2Fe17 in the ribbon-shaped material 18 is oriented in the cooling direction. The ribbon-shaped material 18 can be milled and nitrided while omitting a homogenizing treatment step and an oxide layer removal step because of its freedom from α-Fe. The nitrided material is further ground, and the resultant Sm-Fe-N magnetic powder is pressed in a magnetic field, by which an anisotropic bonded magnet in which a specific plane is oriented in a direction orthogonal to the direction of the magnetic field can be obtained.

Abstract: PURPOSE:To provide a method for connecting a part to a circuit board using a conductive adhesive agent, capable of obtaining low connection resistance. CONSTITUTION:When an electrode 32 of a part connected to a land 22 of a circuit board with a conductive adhesive agent 1, the conductive adhesive agent is hardened by heating under pressure.

As the thermosetting adhesive use may be made of an adhesive containing a filter or a silicone based adhesive. Therefore, it is possible to warkedly reduce the resistivity in the direction perpendicular to the board, namely, the connection resistance, by hardening the conductive adhesive under heat while applying pressure.

Filed: 1988-07-06
Abstract: PURPOSE:To simplify a circuit configuration, and to control stable rotation even at the time of high speed operation by controlling a current flowing to phase windings by an output voltage from a DC/DC converter. CONSTITUTION:A DC/DC converter 12 is composed of a coil Lx as an inductor connected in parallel with a DC voltage source 14 through a transistor Tx, a capacitor Cx connected at its one end to one side terminal of the coil Lx, and a diode Dx for connecting the other end of the capacitor Cx to the terminal of the coil Lx at the side of the transistor Tx. A voltage across the capacitor Cx, i.e., an output voltage to be applied to a phase winding is determined by the ON period of the transistor Tx. Thus, a voltage control by the converter can be conducted independently irrespective of the rotating speed of a variable reluctance motor, a stable rotation control can be realized even at the time of high speed operation of the motor.

Abstract: PURPOSE:To eliminate not only an impulsive noise but also an usual noise by applying real time DFT so as to calculate the spectrum of a signal in the frequency space, applying arithmetic processing thereto and applying IDFT to the signal so as to decode the signal into the original signal. CONSTITUTION:A voice signal (discriminator output) X (t) being an input enters a sample-and-hold circuit 26 through a low pass filter 24 preventing a reflection error, is sampled by a sampling frequency fs, digitized by an A/D converter 16 into a data x(n), which is subject to discrete Fourier transformation (DFT) to obtain a spectrum X(k). A component corresponding to a noise frequency component is excluded (nullified) from the X(k), inverse Fourier transformation (IDTF) is applied, the result is DA-converted and given to an interpolation LPF 24 to obtain a voice signal eliminating noise. Since a specific spectrum is eliminated completely, not only the impulsive noise but also the entire usual noise is eliminated.
