Inventor: HAYAMIZU MAKOTO
IPC: F02M69/04
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To increase a jetting speed of fuel and reduce its dripping, by forming a shape of each connection passage injecting fuel to each branch intake port respectively into a tapered shape, in a fuel injection passage structure provided with a fuel injection valve in the downstream location from a branch location of the intake port. SOLUTION: The downstream of an intake port 4 connected to an internal combustion engine 2 is made to branch in the first/second intake ports 8, 10, and a single fuel injection valve 6 injecting fuel to the first/second intake ports 8, 10 through the first/second connection passages 12, 14 is arranged in the downstream from this branch location. Here, the first/second connection passages 12, 14 are respectively formed into a tapered shape gradually contracted toward the downstream from the upstream. Thus by holding a high jetting speed of injection fuel, fuel sticking to the first/second connection passages 12, 14 is jetted with injection fuel to the first/second intake ports 8, 10, and dripping of fuel from the first/second intake ports 8, 10 and the first/second connection passages 12, 14 is decreased.

Title: Noise removing circuit
Inventor: OOKATA HIROFUMI
IPC: G10L13/07
Filed: 1988-09-30
Abstract: PURPOSE:To surely remove high frequency noises generated at a discontinuous part of a joint and to connect two speech patterns smoothly by comparing a pattern generated by a noise removal pattern generation part with a digital speech pattern which is being inputted currently. CONSTITUTION:When an operation start signal 4 is inputted, it is judged repeatedly whether or not a pattern is present on a digital pattern input line 3. When the pattern is present, the difference between a pattern generated by a noise removal pattern generation part 1 and the pattern which is inputted currently is calculated and the difference data is stored in a register 2a. Then, when the difference is not within a constant range, the difference data is sent out to a noise removal pattern generation part, but an operation stop signal is not outputted. This starting operation is repeated and when the difference enters the constant range, the operation stop signal is outputted. Consequently, high frequency noises generated at discontinuous points are removed and a waveform B which varies smoothly and connects with a waveform C can be generated.
