Filed: 1979-05-28
Abstract: PURPOSE:To give the muting to the excessive noise and then realize the stable reproduction, by securing the muting state when the number of errors to be caused in a fixed time exceeds the fixed level and releasing the muting state when the number of errors is less than the fixed level each. CONSTITUTION:Counter 10a which counts the number of errors with the outputs of error detecting circuit 4 and isolating circuit 2 used as the input each is installed to muting circuit 10 os the PCM reproducer which uses the digital signal obtained by coding the analog signal for the data and then decoding the data row including the error check code in order to reproduce the original analog signal. The outputs sent from terminal Q and counted by counter 10a are applied to comparators 10b-10d, and the signals of H levels are delivered when the count value is higher than the prescribed level and via comparators 10b-10d. Then OR circuit 10e gives the decision to the conduction of the cut-off of the reproduced output signal. And the control is given to set priority RFFF10g via the outputs of circuit 10e and comparator 10d, thus changing the muting state.

Title: Semicontactless bearing made of magnet
Inventor: KOYAMA EISHIN
IPC: F16C32/04
Filed: 1979-05-29
Abstract: PURPOSE: To economically manufacture the contactless bearing fixed in the air, by combining two inner and outer permanent magnets, and supporting the inner shaft at one point through utilization of properties of magnets.  
     CONSTITUTION: The inner magnet 1 serving as a shaft is disposed on the inside of the outer magnet 2. The inner magnet 1 is formed with a small hole at its center and a sheet 6 is attached to the inner magnet 1. When the magnet 1 is placed at the center of the outer magnet 2 with a needle-like shaft 4 being inserted into the small hole, magnet 1 is fixed in the air but its rotation is free. Subsequently, when a magnet 3 having the same form as the magnet 2 is drawn near to magnet 1 in the state that the polarity of the magnet 3 is repulsive to that of the magnet 2, the magnet 1 is afforded with a force capable of supporting the upper shaft 7. When the magnet 1 has come to a point where the repulsive force is maximal, the magnets 2, 3 are fixed by means of connecting member 8. Here, if the needle-like shaft 4 is bonded firmly to the center of a plate 5 that is fixed to magnet 3, the shaft 7 supported in the air only at the contact point of sheet 6 and the shaft 4 can be obtained. Thus, it is enabled to obtain a bearing having an extremely low frictional resistance and an extremely high sensitivity to rotation.
