摘要： A mechanism for automatically returning a tone arm of a toy phonograph from the final to the starting positions of a reproduction. A swingable rod is provided for lifting an intermediate sound transmitting body which usually depresses the tone arm, when the tone arm has been brought to the final position of the reproduction, so as to allow the reproducing needle carried by the tone arm to be disengaged from the recording groove, thereby enabling the tone arm to return. The upward movement of the swingable rod is initiated by an engagement of the rod with a cam contour formed on the drive shaft for the record disc. In order that the swingable rod may correctly ride on the cam contour, so as to be lifted by the latter to make the tone arm free from the depressing force of the intermediate sound transmitting body, there is provided a buffer resilient body adapted to absorb the movement of the swingable rod and the movement of the tone arm which presses the rod toward the cam. By the absroption of these movements, the tone arm is allowed to swing, even after the swingable rod has collided with the higher side of the cam contour, so as to make the swingable rod stationary until the lower side of the cam contour, on which the swingable rod is destined to ride, is brought to confront the swingable rod.

摘要： In a phonograph of the type wherein, during playback, a pickup arm travels in sliding contact with an overlying intermediate vibrator for transmission of stylus vibrations thereto, a lever is fulcrumed at its intermediate point on the intermediate vibrator. A constant force is applied to one end of the lever, as by a spring, and the other lever end is urged against a loudspeaker diaphragm rigidly supported by the phonograph casing, so that the vibrations of the intermediate vibrator are transmitted via the lever to the diaphragm to cause same to produce corresponding sound waves. Preferably, the distance between the said other end and fulcrum of the lever is at least equal to the distance between the said one end and fulcrum of the lever.

摘要： A simplified sound-reproducing device including a constant-torque spiral spring for driving a turntable on which a phonograph record is irreplaceably mounted. The spiral spring is unwound as a manual pull is exerted on a string extending out of the device, and upon release of the string, is rewound to its initial configuration, thereby causing the turntable to rotate in a predetermined direction. A reproducing stylus on a pivotal pickup arm rides in the groove on the record, and the vibrations set up in the stylus and pickup arm during record rotation are directly transmitted to a diaphragm to cause the same to emanate audible sound. Measures are taken against diaphragm deformation due to heat or shock which may be caused through the pickup arm.

摘要： A system and method for performing ranging and positioning as follows by using the procedure for packet transmission and reception between a sender and a recipient. A first radio set transmits packets to a second radio set as a recipient. The second radio set returns the packets without fail after the lapse of time (from the detection of packets) which corresponds to an integral multiple of a prescribed unit time. The first radio set counts, by using its counter, the time which has elapsed from its transmission of packets to its detection of packets from the second radio set. The remainder of the thus counted time after subtraction of the time taken by the second radio set from packet detection to packet return and the processing time of the first radio set itself is converted into the distance of propagation between the first radio set and the second radio set as a recipient.
