Abstract: PURPOSE:To provide the possibility of absorbing quantitative error caused by manufacturing error in a fuel injection nozzle wherein lift of a needle valve can be restrained, by successively forming two tapered parts differing in tapered angle, at the end of the needle valve. CONSTITUTION:Fuel injection is performed from a jet 18 by a fuel injection nozzle 6 such that the pressure of fuel sent into a pressure chamber 15 pushes a needle valve 13 against a spring 24 to be opened.

Title: Compensating system for inter-code interference
Inventor: KOBAYASHI KOUICHI
IPC: H04L25/03
Filed: 1981-03-19
Abstract: PURPOSE:To realize the simplification and miniaturization of a circuit, by increasing or decreasing the gain of a low frequency compared with the pulse repetitive frequency and compensating the inter-code interference. CONSTITUTION:An input signal (a) is equalized by an equalizing amplifier 8, and the output waveform of the output signal (b) is obtained as shown by the figure. In this case, an inter-code interference detector 9 detects the inter-code interference after the peak value of the output waveform elapses from the time 0 through T0. Thus the gain control signal is transmitted to the amplifier 8 to increase and decrease the gain in case the code waveform obtained after the time T0 elapses is minus (-) and (+) like B respectively. In such way, the amplifier 8 increases or decreases the gain of a low frequency compared with the repetitive frequency F0=1/T0 by means of the gain control signal. As a result, an ideal equalizing signal as shown by the waveform A is converted into the output signal (b).
