    • A novel electromagnetic balance-type weighing apparatus according to the invention includes a weighing pan/balance beam assembly (15) whose balance beam is angularly displaced as a function of the weight of an object of weighing placed on the weighing pan. An electromagnetic coil (9) is provided to generate an electromagnetic force that offsets the displacement of the balance beam of the weighing pan/balance beam assembly (15) caused by the weight of the object of weighing. A displacement detector (3, 4, 5) is provided to detect the displacement of the balance beam of the weighing pan/balance beam assembly (15). An operation unit (7) performs operations to determine a control voltage in response to the detection signal transmitted from the displacement detector (3, 4, 5). A current transducer circuit (20) generates an electric current in response to the control voltage applied to it by the operation unit (7) and supplies it to the electromagnetic coil (9). The current transducer circuit (20) comprises a negative feedback loop circuit for feeding the output current from said current transducer circuit (20) back to the input terminal of the current transducer circuit (20). A weight calculator (24) calculates the weight of the object of weighing from the output current of the current transducer circuit (20).

    • A method for transmitting and extracting a timing signal for use in a multi-carrier parallel data transmission system having the carrier frequencies of channels arranged at baud rate intervals. On a transmitting side, two pilot signals, whose frequency difference is an integral multiple of the baud rate, are inserted outside the signal band of said data transmission system and transmitted to a receiving side. On the receiving side, the frequency difference signal of said two pilot signals is taken out and is frequency-divided to extract a timing signal equal to the baud rate frequency. By this use of two pilot signals, it then becomes possible to transmit and extract a timing signal without sacrificing any of the valuable carriers contained within the data transmission band.

    • A diaphragm control mechanism for a camera objective wherein the diaphragm aperture is maintained fully open before camera operation in order to facilitate framing and focusing of the objective system and is then stopped down in response to a camera release operation to a value manually preset or automatically determined. The fully open diaphragm aperture is adjusted in accordance with movement of a component or components of the objective for the sake of adjustment of the objective, for example, to change its focal length. The improvement according to the present invention lies in the construction of the fully open diaphragm aperture adjusting mechanism wherein a movable member which is included in the link system for the stopping down of the diaphragm bears against a periphery cam or cam edge of a fixed member fixedly mounted in the lens barrel of the objective independently of the link system so that the fully open diaphragm aperture is adjusted as a function of the contact point between the movable member and the cam, with the movable member being allowed to move away from the cam upon the diaphragm stopping down operation of the link system.

    • A method of producing a grain-oriented electromagnetic steel sheet comprising the step of subjecting a sheet of hot-rolled steel containing silicon less than 4.5% to more than one operation of cold rolling and more than one operation of annealing, so as to set the thickness of said sheet to that of a commercially standard sheet, and also subjecting the sheet to the step of final high-temperature annealing. Prior to said final high-temperature annealing, part of the surface of said sheet is worked for controlling the growth of secondary recrystallization grains by working the sheets such that lines of less than 3.0 mm wide are formed on the surface of the steel sheet spaced apart at intervals of more than 5.0 mm so that the total effect is to produce worked and unworked regions alternatively arranged in lines across the steel sheet. Such working is effected by mechanical plastic working, local thermal treatment and by chemical treatment. The worked regions serve to control the growth of secondary recrystallization.
