Title: Combustion chamber of internal combustion engine with precombustion chamber
Inventor: NAKAMURA NORIHIKO
IPC: F02B19/12
Filed: 1978-07-20
Abstract: PURPOSE: To provide stable growth of flame injected from precombustion chamber within main combustion chamber by allowing the flow way direction of precombustion chamber to make the depress section of cylinder head internal wall surface which may not be effected by squish flow.  
     CONSTITUTION: With the combression stroke, a part of squish flow D injected from squish area B generates a microturbulence within flow way 8, and the remaining large part generates turbulence flow E around the horizontal squish area A. A flame from precombustion chamber 7 is injected into the depress section 14 located on the cylinder head internal wall surface 3a where squish flow C, D may not be effected by directional way of communication way 8. This allows to develop stable flame in the main combustion chamber 4 by preventing from blowing off by cyclone flow E.

Title: Simulator for phasing state
Inventor: TAKENAKA SADAO
IPC: H04B3/14
Filed: 1980-06-30
Abstract: PURPOSE:To make a constant-value phase shift over a wide range by mixing a transmission-line signal, a fixed-frequency signal, and a phase-shifted fixed-frequency signal successively and by extracting only a phase-shifted trasmission-line signal from the mixture signal. CONSTITUTION:The output of a fixed-frequency oscillator OSC is phase-shifted by a phase shifter PSF, whose output signal is mixed with a transmission-line signal inputted to a variable phase shifter PHS by a signal mixer MIX1. Then, a band- pass filter BPF1 extracts a required frequency component, which is remixed with the output of the OSC which is not shifted in phase. The mixture signal is passed through a band-pass filter BPF2 to extract only a phase-shifted transmission-line signal. Consequently, the transmission-line signal is shifted in phase as much as the extent that the phase shifter PSF determines without any influence of its frequency, so that the secure simulation of a phasing state is achieved by using a variable phase shifter which makes a constant-value phase shift over a wide range.
