Title: Combined bushing
Inventor: KONISHI KEIZOU
IPC: F16F13/00
Filed: 1980-05-30
Abstract: PURPOSE:To improve a damping property against high and low-frequency vibration, by providing a pair of recesses, which are filled with incompressible liquid, on a rubber sleeve provided between the inner and outer cylindrical metals of a combined bushig for the buffer joint of an automobile suspension and by connecting the recesses to each other through an orifice and communication passages. CONSTITUTION:Under low-frequency vibration, clearances 7 are tightly closed so that liquid moves between recesses 4 through an orifice 5. Damping ise caused by the flow resistance of the orifice 5. For that reason, a good damping property is attained independently of the material of a rubber sleeve 3. Under high-frequency vibration, the clearances 7 are not closed and opened quickly enough. For that reason, the recesses 4 communicate with passages  so that the liquid easily moves through the passages 6. As a result, a phase difference is made between the speed in the direction of the vibration and that in the direction of the movement of the liquid to apply negative pressure to lower the dynamic spring constant of the rubber sleeve 3. The damping property against the high and low-frequency vibration is thus heightened.

Filed: 1988-03-26
Abstract: PURPOSE:To prevent a short-circuit current from flowing in a transistor on which the signal is impressed even when an external input signal is in an unstable condition by providing a means with the output of the OR of an internal cell output signal and the external input signal as an internal cell input signal. CONSTITUTION:The title cell consists of diodes 2 and 3 and a resistance 1 for electrostatic protection, and P-channel transistors 4 and 5, N-channel transistors 6 and 7 and a driver 8 for driving to compose the OR. Since an input cell with the output of the OR of an internal cell output signal 11 and an external input signal 10 as an internal cell input 12 is built, the propagation of the external input signal 10 through the internal cell can be controlled by the internal cell output signal 11. Thus, even when the external input signal 10 is in the unstable condition, the condition is prevented from propagating to the inside and the short-circuit current can be prevented from flowing also inside the input cell to which the condition is inputted directly.

Title: Color killer circuit
Inventor: INOUE SHUJI
IPC: H04N9/70
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To execute killer operation at the time of the television signal input of a weak electric field and also at the time of video input of a stable level by executing killer judging operation by switching the color-demodulating output of a burst signal and the ACC wave-detecting output of the burst signal by the large/small relation between a burst signal amplitude level and a reference value. SOLUTION: A Y/C separation circuit 22 separates a composite video signal into a luminance signal and a carrying color signal, and a color demodulation circuit 27 demodulates the carrying color signal into an R-Y signal and a B-Y signal via an ACC circuit 24. A color killer circuit 28 comparing this value with a reference value turns a color signal output interruption circuit 28a ON/ OFF corresponding to the large/small relation of the comparing results. Killer judging operation can be executed by driving the circuit 28a by switching a color modulating output and the output of the circuit 24 of the burst signal by a switch 28c. Thus, killer operation can be executed by detecting burst signal amplitude even by a television signal in a bad receiving state where noise is superimposed in a burst signal period.
