Title: Eliminating circuit for energy diffusion signal
Inventor: NAKAO TAKAO
IPC: H04B1/12
Filed: 1979-06-18
Abstract: PURPOSE:To secure an assured elimination of the energy diffusion signal, by utilizing the diffusion signal of opposite phase which is obtained based on the peak value detection signal of the piled signal of the energy diffusion signal. CONSTITUTION:Peak signal A of the diffusion signal is obtained at diffusion signal peak detecting circuit 16 with the input video signal. Then the maximum peak signal is extracted through maximum peak detecting circuit 17, and then minimum peak signal obtained by applying signals B and A to exclusive logic sum circuit 18 is applied to FF19 as the reset signal to obtain square waveform D. This waveform D is converted into triangular wave E through integrating circuit 20. At the same time, two outputs having the reversed phases are obtained from FF19, and here the terminal which delivers the triangular wave having the opposite phase to the piled diffusion signal is used. Then the video signal is mixed with triangular wave E through mixer 21 in order to eliminate the diffusion signal.

Title: Control device for automatic transmission
Inventor: NOBEMOTO HIDETOSHI
IPC: F16H61/12
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To stably improve engine reliability by changing the gear ratio of a transmission to a lower level, upon the rise of an engine speed up to a level equal to or above the preset upper limit value. SOLUTION: During the drive of a vehicle, a friction factor μ is detected with a surface friction factor sensor 107, while a travel speed V is detected with a travel speed sensor 102, thereby establishing an engine speed upper limit value and an engine speed lower limit value. When a target engine speed is lower than the engine speed upper limit value but higher than the engine speed lower limit value, with a transmission kept in a manual shift mode, a gear position is kept unchanged. unless a gearshift lever operation is instructed. Also, when the target engine speed becomes equal to or above the engine speed upper limit value, the gear position is shifted, thereby automatically changing a gear ratio to a lower level. According to this construction, the improvement of engine reliability can be stably maintained.
