摘要： A transducer for converting electrical energy into mechanical or acoustic energy or vice versa using a converting means made of a thin film of high molecular weight polymer piezo-electric organic compound having orientated molecules and having electrodes bonded or deposited onto both surfaces thereof. When an electric current is applied to the electrodes, the thin film is extended or contracted in a direction different from the direction of orientation of the molecules. when the angle between these two directions is 45*, the extent of the extension or contraction of the thin film is at a maximum and the best converting efficiency can be obtained.

摘要： A MAGNETIC TAPE CARTRIGE ADAPTOR FOR PLAYING A SMALL SIZED ENDLESS TAPE CARTRIDGE WITH A CONVENTIONAL TAPE RECORDER UNIT. THE CARTRIDGE ADAPTOR HAS THEREIN A LOADING BOX INTO WHICH THE SMALL SIZED CARTRIDGE MAY BE INSERTED FOR PLAYING. LOCKING MEANS ARE PROVIDED FOR FIXING THE SMALL SIZED CARTRIDGE IN POSITION WITHIN THE LOADING BOX, AND A SWITCHING MEANS IS USED FOR PERMITTING THE TAPE RECORDER UNIT TO PLAY UPON INSERTION OF THE SMALL SIZED CARTRIDGE. THE CARTRIDGE ADAPTOR IS ALSO PROVIDED WITH A DRIVING ROLLER TO DRIVE THE TAPE IN THE SMALL SIZED CARTRIDGE WHICH IS DRIVEN BY A CAPSTAN IN THE TAPE RECORDER UNIT THROUGH AN IDLER, A RECORDING AND REPRODUCING MAGNETIC HEAD, AND AN ELECTRICAL SENSING POST. WHEN THE SMALL SIZED CARTRIDGE IS INSERTED INTO THE LOADING BOS, THE LOCKING MEANS CAN ENGAGE WITH RECESSED PORTIONS FORMED ON BOTH SIDES OF THE CARTRIDGE, AND THE CARTRIDGE ACTUATES THE SWITCHING MEANS TO START THE OPERATION OF THE TAPE RECORDER UNIT, WHEREBY THE DRIVING ROLLER IS DRIVEN TO TRANSPORT THE TAPE IN THE SMALL SIZED CARTRIDGE.

摘要： A locking device for a tone arm comprising a tone arm lifter and a tone arm rest. The arm lifter is arranged so that the outer end portion of the lift plate is formed with a curved hook-like portion, the outer end of which is bent inwardly. The seating plate of the arm rest is provided with a rising curved portion, at least in its inner side part. The hook-like portion of the arm lifter and the rising portion of the arm rest form an aperture having a restricted opening between the outer end of the hooklike portion and the top of the rising portion, wherein the tone arm is captively located and clamped when the arm is out-of-use.

摘要： An automatic telephone answering device wherein a message recording tape is started to run simultaneously with the start of running of an answering tape having an answer signal recorded thereon. The message recording tape is recorded on its first track with only the answer signal and on its second track with a composite signal consisting of the answer signal and the incoming message signal. At the time of reproduction, the answer signal on the first track of the recording tape is phase-inverted and the composite signal reproduced from the second track of the recording tape is mixed with the phase-inverted answer signal to cancel the answer signal, whereby only the message signal is audibly reproduced by a speaker.

摘要： The time required to electronically transmit the contents of a document, such as a picture or a printed paper, is markedly reduced. The document is divided into minute squares and each square is scanned by a preliminary scan for detecting the presence or absence of useful information. The preliminary scan is much more rapid than the regular scan used for forming a transmittable document image. Only those squares having useful information are scanned by the regular scan to form images which are transmitted. Sync pulses and shift pulses are transmitted along with the image signals to allow the receiver to properly position the image signals in generating a reproduction of the document.

摘要： A magnetic tape magazine playing device which has a rotatable lever having a pinch roller attached to one end thereof, an operating lever having a claw for pressing one end of the rotatable lever and constructed so that the interval between the pinch roller and a capstan is substantially the same as the stroke of the operating lever. Also, electric contacts are provided which function so that one group of electric contacts close so as to rotate only the capstan upon the former half stroke of the operating lever and the other group of electric contacts close upon the latter half stroke of the operating lever so that the pinch roller contacts the capstan substantially simultaneously upon the closure of the other electric contacts.
