IPC: H04B10/07
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To increase the array density of a soliton pulse and to obtain an optical reciever that is used for a very high rate mass optical transmission system by making a return-to-zero digital optical signal and light of constant amplitude incident, converting the light of constant amplitude into an optical pulse signal obtained by inverting the on-off of the return-to-zero digital optical signal and modulating an inverted light pulse signal by means of a phase modulator. SOLUTION: 20G b/s dark soliton optical signal which is subjected to time division four multiplexing and an output of a CW laser 201 are made incident an eclusive-OR optical gate 200 and CW laser beams are converted into a time division multiplex optical signal obtained by inverting the on-off of the dark soliton optical signal. The time division multiplex optical signal is branched into two by an optical coupler 202. A photodetector 203 converts a part of it into an electric signal, a narrow-band filter 204 extracts 20G b/s clock frequency components and a frequency divider 205 converts it into a clock frequency before 5G b/s multiplexing.

Title: Cylinder air flow generating method for internal combustion engine
Inventor: SUKEGAWA YOSHIHIRO
IPC: F02B31/00
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To control a vortex strength with high quality of a vortex kept, in a spark ignition engine intending to effect stratified combustion by using a vortex flow in a cylinder. SOLUTION: In this engine, a suction port 1 is provided with a partition wall 3 and a tumble control valve 6 and a suction valve 5 is opened and closed by electromagnetic solenoid 9a and 9b. In this case, during stratified operation, the tumble control valve 6 is half-opened and the closing timing of the suction valve 5 at the initial stage of a compression stroke is retarded. Tumble is reinforced by a tumble control valve and by effecting close-in-delay of the suction, air reversely flows to a suction port and a secondary vortex in a cylinder disappears. This constitution generates tumble of high quality even when a tumble control valve is in an intermediate opening state.
