Abstract: An electromechanical and electroacoustic transducer is compact and has a simple drive circuit. Two independent magnetic circuits share a single permanent magnet. A voice coil is placed in one of the magnetic circuits, and a magnetic weight is placed in the other magnetic circuit. A switching element is turned on and off upon movements of the magnetic weight.

Abstract: Herein disclosed is an image transmitting and receiving system comprising a plurality of image transmitting apparatus and one or more image receiving apparatus. Each of the image transmitting apparatus includes a plurality of camera units (10a to 10e) each for taking a moving picture of an object and a compressing and encoding unit (26) for compressing and encoding the moving image to generate coded moving image signal data. Each of the image receiving apparatus includes one or more decompressing and decoding units for decompressing and decoding the coded moving image signal data, and a monitoring unit (51) having a screen for displaying one moving picture on the screen when one moving image signal is outputted by the data outputting unit (58), and displaying a plurality of moving pictures on the screen when the synthesized moving image signal is outputted by the data outputting unit (58).

Abstract: An automatic document conveying device for an image-processing machine including a housing having on its upper surface a transparent plate on which to place a document to be processed. The device includes an opening-closing frame member mounted on the housing so that it is free to pivot about a pivot axis extending along the rear edge of the transparent plate between a closed position at which it covers the transparent plate and an open position at which it exposes the transparent plate to view; a stationary frame member to be mounted on the housing adjacent to the upstream end of the transparent plate; a document table disposed on the stationary frame member; a document sending unit for sending a plurality of sheet-like documents placed on the document table to a document carrying-in passage one by one; and a document carrying-in unit for introducing the sheet-like documents sent to the document carrying-in passage toward the transparent plate.

Abstract: A container having an easy open type closure having a pull tab opening member which is adhesively fixed to the top surface of the closure of the container. The adhesive member is made of a resinous member comprising a copolymer of .alpha., .beta. unsaturated carboxylic acid or ionomer resin containing a phenol series antioxidant.

Abstract: A combustion pressure peak detector comprised of a pair of flat annular piezo-electric elements separated by a flat metal electrode plate are located on a bolt for securing a cylinder head to a block of an internal combustion engine. The piezo-electric elements are engaged on opposite sides by two pressure plates adapted to engage the head of the bolt and the cylinder head respectively. At least one of the pressure plates may have a cup-shaped configuration for enclosing the piezo-electric unit and an inter-fitting projection and notch arrangement may be provided on the respective pressure plates to prevent relative rotation between the two pressure plates during tightening of the bolt.

Abstract: A display circuit adapted for use in an electronic calculator comprises a circuit for enabling communication between the calculator and the operator to inquire as to the value of one or more variables and a circuit for pointing out the kind of a variable which is presently subject to inquiry and input data items entered by the operator. In another form of the present invention, the display circuit comprises a circuit for detecting a space or separable portion between two algebraic expressions, a circuit for terminating the indication just before the position of the space, and a circuit for subsequently initiating indications of items following the space from the top digit of a display.

Abstract: A keyboard entry circuitry for calculator purposes is of the key strobing type wherein one each end of respective key of a keyboard is operatively coupled with corresponding digit time signal or key strobing signal while the other ends of the respective keys are connected in common with each other, whereby the identity of a specific actuated key is provided by determining which one of the key strobing signals is developed via that actuated key. Two kinds of digit time signals are placed within a one-word time sequence, one having different timing phases for the respective keys for key strobing purposes set foth above and the other having the same timing phase for all the keys for shortening a period of time required for key determinations. Once there is a equivalency with respect to both the key strobing digit time signals and the common digit time signal, the indication of any actuated key is provided.

Abstract: A display energizing circuit associated with calculators for displaying on a time sharing basis numerical or alphanumerical symbols on a multi-digit gas discharge panel. Means are provided for preventing segment signals from being applied to segment electrodes or cathode electrodes of the gas discharge panel at one or more dead digit times which are provided within a one-word time period for other purposes. This avoids damage to circuit elements in the display energizing circuit, for example, switching transistor elements associated with counter electrodes or anode electrodes of the display panel.

Abstract: A large scale integrated circuit central processing unit for calculator applications generally includes at least one information storage register and means for generating a word time signal designating the effective digit capacity of the information storage register. An additional external terminal is provided for the package of the integrated circuit to accept control signals applied thereto which are effective to modify the pulse width of the word time signal. Application of the control signals to the external terminal renders the word time signal generating means operative to enable the modification in the pulse width of the word time signal and hence in the effective digit capacity of the storage register.
