    摘要: An optical disc apparatus generates a tracking error signal and a focusing error signal for an objective lens. In addition, the apparatus generates a tracking sum signal or a focusing sum signal for the objective lens. The apparatus multiplies the sum signal by the tracking error signal and the sum signal by the forcing error signal. Corresponding to the results of multiplications, the apparatus moves the objective lens in the tracking direction and focusing direction.

    摘要: A control system for controlling a plurality of control elements, which are effective to control of a given controlled system, is disclosed. In this control system, a characteristic value representing the characteristic of a given controlled system to be controlled is detected, and respective optimum manipulated variables of the plurality of control elements are derived on the basis of the detected characteristic value. The optimum manipulated variables are derived by setting a plurality of reference patterns representing different features of the characteristic value on the basis of a predicted value of the characteristic value, deriving degree of conviction that the detected characteristic value belongs to each of the reference patterns, presetting rules whereby a manipulated variable of each of the plurality of control elements is determined when the detected characteristic value belongs to each of the plurality of reference patterns, and deriving a manipulated variable of each control element on the basis of degree of conviction that the detected characteristic value belongs to each of the plurality of reference patterns and the manipulated variable determining rule preset with respect to each control element for each reference pattern.

    摘要: The process for preparing a ferrochromium by using a blast furnace is improved by charging briquettes or pellets containing chromium ores and a carbonaceous reducing agent into the blast furnace, as well as by determining the operational conditions of the blast furnace, such as the theoretical combustion temperature at the tuyere ends and the pressure at the top of the blast furnace. According to the improvement, the degree of reduction chromium ore is high, and the blast furnace operation can smoothly performed without accidents, such as scaffolding and flooding.

    摘要: Each item in a transaction has a card or ticket having markings signifying its price and category in machine readable form. As each item is purchased, the ticket is inserted into an automatic read-out system. The price and category markings are transduced into signals stored in a first and second buffer storage, respectively. A code converter connected to the second buffer storage operates to furnish a pulse to a corresponding one of a plurality of counters in response to each category signal. The signals in the first buffer storage are added, in turn, by a price adder whose final output therefor shows the total price of all items in the transaction. A grand total adder operates in parallel with the price adder and is cleared after predetermined time periods rather than after each transaction. The signals from the price adder and the grand total adder are supplied through multiplexers to series display and printout devices. A switch is furnished to convert the system to a computer only by disabling the print-out, display, and grand total circuits.

    摘要: Provided is an antenna device, having a small and simple configuration, which reduces connection resistance in connections between a film antenna element and a power feeding unit. An antenna device comprises a nonconductive transparent film, which is an insulating substrate having a prescribed optical transmission factor, an antenna element that is formed, upon the transparent film, from transparent conductive material, which is a conductive material having a prescribed optical transmission factor, and a non-transparent conductive power feeding wire. The transparent film and the transparent conductive material are doubled over and pressed upon a portion of one side of the antenna element, which forms a square dipole antenna, such that the transparent conductive material is on the inside, and the power feeding wire is sandwiched therein. By being doubled over, the transparent conductive material has an overlap portion, the two sides whereof electrically connect to one other.

    摘要: Provided are a device and a method that can classify an incoming wave and can correctly distinguish the position of an originating device, even in a multipath environment. A principal vertically polarized wave arrival direction sensing unit (104-1) and a principal horizontally polarized wave arrival direction sensing unit (104-2) respectively sense the arrival direction of a principal wave by sensing the arrival direction in which the maximum reception level is obtained. An incoming wave classifying decision unit (108) determines that a direct wave has arrived when the difference between the principal wave arrival direction sensed by the principal vertically polarized wave arrival direction sensing unit (104-1) and the principal wave arrival direction sensed by the principal horizontally polarized wave arrival direction sensing unit (104-2) is within a prescribed threshold value, and determines that a direct wave has not arrived when the difference is greater than the threshold value.
