Title: Linear tracking arm device
Inventor: TANAKA NAOKI
IPC: G11B3/10
Filed: 1981-05-20
Abstract: PURPOSE:To reset a pickup arm to the position equal to rise starting position although the record player is tilted, by detecting the degree of the horizontal turn to hold electromagnetically the raised pickup arm at the original position and then releasing the holding state of the pickup arm after moving it down. CONSTITUTION:A pickup arm 52 which moves with a linear tracking arm 20 along a guide shaft 1 is moved up while a record player is set in slant. Thus the arm 52 has a horizontal turn. The degree of this turning is detected by a Hall element 57 provided between the coils 47 and 48. The arm 52 is reset to the original position to be held electrostatically by the coils 47, 48, etc. which form a horizontal driving motor and a horizontal driving speed sensor together with the yokes 46 and 50, a magnet 49, etc. Under such conditions, the arm 52 is moved down. When this moving-down of the arm 52 is over, and detected by a Hall element 38, the electrostatic holding of the arm 52 is released. Thus the arm 52 can be set down at the position equal to its rise starting position although the record player is tilted.

Filed: 1981-05-19
Abstract: PURPOSE:To obtain a gelling agent for an alkaline-battery negative mixture, which has a stable internal resistance and a good workability, by using the combination of bridged starch and guar gum. CONSTITUTION:3pts.wt. of Mixture prepared by mixing bridged starch and guar gum in a ratio by weight of 1 to 1 is mixed into 97pts.wt. of 40wt% aqueous KOH solution, and the mixture is stirred so as to prepare a gel-like electrolyte.

Abstract: PURPOSE:To prevent sweeping from being stopped in error due to the modulation (modulation frequency) of a broadcast wave at the sweeping by providing a means decreasing the AGC response time constant and switching its time constant to a value at the normal operation in obtaining a tuning detection signal. CONSTITUTION:The AGC circuit 20 is brought into the operating state even in the automatic frequency sweep state and in such a case, the time constant of the AGC circuit 20 is decreased more than that at the steady-state. When automatic frequency sweeping is conducted and a broadcast signal is turned, an intermediate frequency is obtained and it is counted by a counter 21 and when the counting reaches a prescribed number, a detection signal is obtained from the detection circuit 22 and fed to a system controller 23. Then the system controller 23 brings the time constant of the AGC circuit 20 to a value at the steady state. Then in the presence of key entry for channel selection, the system controller 23 inhibits the signal reception from the detection circuit 22 for a prescribed period (e.g., one step variable period) to initiate the automatic frequency sweeping and the time constant is switched and the sweeping is stopped.
