Abstract: A control system for improving the security level of a security device. A portable device is provided with a communication function and has a portable device ID code. A security controller includes a memory for recording a controller ID code. The security controller communicates with the portable device to determine whether the portable device ID code matches the controller ID code, and controls deactivation of security functions for a door lock driver and an engine controller based on the determination result. In response to a restriction request signal, the management apparatus transmits a function restriction signal to the security controller. The security controller prohibits or restricts control of the door lock driver or the engine controller when receiving the function restriction signal and communicating with the portable device.

Abstract: A vehicle lock controller that is easily used. The controller is installed in a vehicle having a plurality of doors and controls locking of the doors through communication with a portable device. The controller includes transmitting circuits, each provided in association with a corresponding one of the doors to output a request signal and request the portable device to transmit a response signal. A control unit is connected to the transmitting circuits to intermittently output the request signal from each of the transmitting circuits at a predetermined cycle. The control unit determines a priority order of the transmitting circuits to set the predetermined cycle of the request signal output from each transmitting circuit in accordance with the priority order.

Abstract: A three-axis antenna chip includes a cross-shaped core made of a magnetic substance. The core includes an X-axis core piece and a Y-axis core piece. The core pieces are laid on top of each other such that the core pieces extend perpendicular to each other. An X-axis coil portion is provided about the X-axis core piece, and a Y-axis coil portion is provided about the Y-axis core piece. A Z-axis coil portion is provided about a Z-axis that is perpendicular to the X-axis core piece and the Y-axis core piece. The three-axis antenna chip thus constructed is advantageous in reducing the size.

Abstract: A minute amplitude value emphasis device 2 has Fourier transformation devices 211, 212 which treat a two-dimensional original pictorial image 200 with a Fourier transformation to determine Fourier coefficients in x-axis and y-axis directions. Weight devices 221, 222 emphasize the respective Fourier coefficients in the corresponding directions so as to produce weighted Fourier coefficients. Inverse Fourier transformation devices 231, 232 treat the weighted Fourier coefficients with an inverse Fourier transformation in two directions to determine the corresponding minute amplitude value emphasis data 241, 242. A synthesizing device 250 synthesizes the corresponding minute amplitude value emphasis data 241, 242 to produce a minute amplitude value emphasis image 260. An obscure portion of the two-dimensional original pictorial image 200 is rectified to reproduce a clarified pictorial image.

Abstract: A method of molding a foamed product is carried out by using a front and a rear mold for molding a front and a rear portion of the foamed product and a core interposed between the front and rear molds. The method includes steps of pouring or spraying one of foaming stock solutions onto a molding surface of the one mold, arranging the core in the one mold and pouring or spraying the other foaming stock solution onto the core or a molding surface of the other mold. The front and rear molds are closed at a moment when a lapse of time arrives at 30-100% of a rise time of the foaming stock solution later applied. Thereafter the closed molds are maintained in a position where an angle of the closed molds relative to a horizontal plane is within a range between 90.degree. and an angle more than 0.degree.. The front and rear molds are pivotally connected to each other with their one ends by means of a pivot shaft. The core is pivotally supported with its one end by a shaft arranged in parallel to the pivot shaft.

Abstract: Stable aqueous emulsions of acrylate polymers, methacrylate polymers or butadiene polymers, which are prepared by emulsion polymerization in the presence of hydrolyzed vinyl acetate-alkali metal olefinsulfonate copolymer as an emulsifier.The aqueous emulsions thus prepared have excellent properties in storage stability, viscosity stability, dilution stability, freeze-thaw stability and miscibility with pigment or urea resin. The emulsion can also give a film excellent in water-resistance.
