Abstract: In effecting the two-color printing from an original which is printed in black and other color by way of a mimeographic printing technique, apparatus for automatically engraving mimeographic stencil papers which decomposes the black or other colors of the original independently into two colors and reads them out to engrave two stencil papers. The engraving apparatus comprises two light-receiving elements (3,4) for reading the contents displayed on the original, color filters having different spectral characteristics which are attached to the light-receiving elements and are faced to the original, and a circuit (C) for selecting the colors to be engraved depending upon the outputs of the light-receiving elements. A single automatic engraving apparatus makes it possible to easily prepare the stencil papers for two-color printing and to reduce the color deviation when the original is set to the engraving apparatus.

The surface of each rotating member is partially exposed through respective ones of the openings, and an arm is provided to rotate with the minute hand so as to individually turn the rotating members.

Abstract: A study device for teaching children or other users predetermined study items, such as letters of the alphabet, in response to depressing desired ones of a plurality of push-plate operating portions. The study device includes a casing having a plurality of study elements provided in horizontal rows and vertical columns. Each study element includes an indication plate having an indication surface formed on the upper surface thereof, and a push-plate disposed below the indication plate, the push-plate including a resiliently supported operating portion. When the operating portion of a particular push-plate is depressed by the child, the indication plate will rotate to stand upright. One resilient member resiliently supports a plurality of the operating portions of the push-plates.

Abstract: A multiplication study device for teaching a student multiplication skills by operation of push-buttons mounted in a box-shaped case. The push-buttons are each provided with a semi-transparent see-through surface which permits the appearance therethrough of an answer to a multiplication problem when the push-button is depressed so as to come into contact with a projecting member disposed therebelow. A plurality of the push-buttons are mounted in the case, and the case includes a rear cover for mounting the projecting members. A common resilient member in the form of a urethane plate is employed for normally urging the push-buttons in an upward direction.

Abstract: A toy including a powered running toy member and a track along which the toy member runs, the toy member being made to run by rotation of the driving wheels of the toy member. The running toy member is provided with a switching arm which is attached to the lower side thereof and is adapted to trigger an operation for changing the running direction, and a mechanism for effecting the change of running direction when actuated by the swinging arm. On at least one end of the track, a mechanism is provided for causing swinging movement of the switching arm to automatically change the running direction of the toy member as the toy member reaches that end of the track. The running toy member has the form of an animal such as, for example, a bird, and incorporates various mechanisms for effecting various actions simulating those of the actual animal, e.g., turning of the head, opening of a beak, etc., by making use of power provided by the driving wheels.

Abstract: An improved small electric motor for use as a power source for toys, small electric instruments, and portable electric instruments, and a method for manufacturing rotors for such motor. The small electric motor is provided on a rotary shaft with a commutator provided in parallel and feeder brushes in resilient contact with the commutator. The commutator is fitted to the rotary shaft in a manner providing simplicity of assembly, adjustable positioning of the commutator on the rotary shaft, standardization of a magnet case, and favorable performance in the small motor.

Abstract: A stereo-viewer and a stereo-sheet for use therewith, includes a set of oculars disposed in a horizontal plane in a case and separated from each other by the distance between the eyes of the user. The case has an insertion slot for accommodating the stereo-sheet which passes in the vertical direction through the case. A frame feeding device is connected to the case for moving the stereo-sheet in the vertical direction. No elements are required to change the direction of the path of the light in a vertical direction.

Abstract: An educational electric motor adapted to be easily assembled and disassembled, comprising a three-part case formed from a central magnetic body connected at each end with transparent front and rear covers. Tape or clamping members are used to connect together the three-part case. An assembled rotor may be easily fitted within the motor case to rotate therein. A current feeding member is removably secured to at least one of the covers.

Abstract: In a permanent magnet motor wherein commutator segments have surfaces arranged in a plane perpendicular to the motor shaft for sliding contact with brushes, each brush is made of sheet metal and comprises an inner portion affixed to an end cap of the motor casing, and a substantially annular outer portion united at one of its ends to the inner portion and having an embossed contact on the other end which is resiliently urged into sliding contact with the commutator segment surfaces. The outer brush portion is notched to engage a protuberance on the end cap. A lubricant reservoir is formed either on the commutator or on each brush. The end cap may be locked in position on the motor casing, and the commutator may be mounted on the motor shaft in a predetermined angular position in relation to that of an armature core.

Abstract: Recording-reproducing apparatus utilizing as the recording medium a rectangular sheet of paper or the like having a spiral magnetic track on one surface and printed material on the opposite surface for audiovisual educational purposes.

The control circuit includes means for automatically suspending the rotation of the drive motor in response to a stop signal generated when, during playback, the magnetic head reaches a specific zone or zones on the track.

Abstract: A teaching machine on which is replaceably mounted a rectangular sheet of paper or the like with a spiral magnetic track on one surface, which is directed downwardly, and with printed material on the other surface for visual presentation of the subject of audio information prerecorded on the track. A movable magnetic head under the sheet follows its track for playback or recording. To afford closer contact between head and sheet and hence to improve the playback quality, a hinged holder frame secures the sheet to the machine casing at its marginal edges only, and the head is spring biased into abutting contact with the yieldably supported sheet. The head itself is supported out of the perpendicular to the plane of the sheet so as to remain in intimate contact therewith throughout its travel along the complete track on the sheet.

Abstract: In a system of overhead projection there is provided a horizontal stage on which is to be placed an object to be imaged. Means for illuminating the object is mounted below the stage at an angle thereto, while a projection lens system is installed above the stage and parallel thereto, in such a position that the axis of the light from the illumination means passes at an angle through its center. A mirror mounted above the lens system projects the undistorted image of the object onto a vertical screen. In another system of overhead projection based on the same principles, the stage and the projection lens system are inclined relative to the illumination means while themselves kept parallel to each other. The axis of the light from the illumination means in this instance extends vertically upwardly and passes at an angle through the center of the lens system. There are further disclosed herein some overhead projectors constructed in accordance with these systems of the invention.
