Title: Head shell of torque damping system
Inventor: MATSUMURA ASAYUKI
IPC: G11B3/42
Filed: 1984-05-21
Abstract: PURPOSE:To suppress the low band resonance levels of both horizontal and vertical directions by applying the 2nd torque damping system consisting of the 2nd shaft having a center line approximately vertical to the center line of the 1st shaft constituting the 1st torque damping system to a head shell. CONSTITUTION:An end of a shaft 10 having a center line B-B' approximately vertical to a center line A-A' of a shaft 3 is fixed to a base 9. The tip of the shaft 10 is sharpened. A mobile base 11 has a pierced bearing hole 12 having a little larger diameter than that of the shaft 10. The silicone grease is filled into a gap between the shaft 10 and the hole 12. A permanent magnet 13 containing the N polarity on its surface is set opposite to a permanent magnet 7. Thus the base 11 is held with a fixed clearance 14 secured to the fixed base 9 owing to the sucking power of both magnets 7 and 13. Then the low band resonance characteristics of a horizontal signal receive the torque damping around the line A-A' in the reproduction mode of a cartridge 5 owing to the viscosity of the silicone oil applied between the shaft 3 and a bearing hole 4.

Abstract: PURPOSE:To prevent an output leakage current by bringing the source potential of two n-channel MOS transistors(TRs) of the pre-stage driving a gate of an insulation gate type TR connected to an external output terminal to a base potential VBB. CONSTITUTION:The base potential VBB is applied to sources of TRs Q2 and Q4. Moreover, threshold values Vth2, Vth4 of the TRs Q2 and Q4 are selected to exceed respectively lVBBmaxl. Thus, TRs Q1 and Q3 are cut off when nodes N1, N2 reach both nearly the VCC potential, and the TRs Q2 and Q4 go to an energized state. Thus, both nodes N3, N4 reach nearly the potential VBB. Then, TRs Q5 and cut off completely, and the external output terminal reaches a high impedance state. In bringing the output terminal to the high impedance, then the output TR is completely turned off to prevent the output leakage current.

Abstract: PURPOSE:To improve acceleration properties through increase of an engine output, by a method wherein, when a combustible maximum injection amount exceeds an allowable maximum injection amount under the acceleration running state of an engine, a combustible maximum inejction amount of fuel is fed to an engine. CONSTITUTION:Based on outputs from sensors 1 and 2, a CPU 11 computes a deviation between the desired value and the actual value of the number of revolutions of an engine. Based on an output from a sensor 3, a maximum injection amount responding to a supercharging pressure is read from a memory 5, and the injection amount or an injection amount based on said deviation, whichever is low, is selected as a first desired injection amount. Further, based on an output from the sensor 2, a maximum injection amount responding to the number of revolutions of an engine is read from a memory 6, and the inejction amount or the first desired injection amount, whichever is low, is selected as a second desired inejction amount. In this case, during acceleration of the engine, a control rack 7 is controlled so that an amount of fuel injected with the aid of a pump 8 is adjsuted to the first desired injection amount.

Filed: 1981-06-30
Abstract: PURPOSE:To remarkably reduce the response time until the end of connection of cross points, by performing scanning for the switching of cross points normally and scanning for the input of a connection designating signal only at new input. CONSTITUTION:An operation switch section 2 outputs a horizontal path information Yn of a switch to a Y coordinate switching section 4 when an address signal of the switch from a CPU1, e.g., Xn is inputted, and the CPU1 inputs the Yn not saved via a line C as a connection designation signal. The CPU1 normally performs cross point scanning switching the cross point of a cross point connection section 3 and executes the switch scanning for a prescribed timing only to save the said inputted designation signal. The CPU1 performs the control of the cross point with the said designation at the execution of the further cross point scanning without counting up of the address Xn during the cross point scanning.
