IPC: F02B23/08
Filed: 1989-03-20
Abstract: PURPOSE:To make the combustion time on weak swirl side and strong swirl side coincide the each approximately by forming the side wall of a combustion chamber out of a part of a conical surface serial to the valve seat of an intake valve, and installing an ignition plug on the conical surface. CONSTITUTION:The roof wall surface on the cylinder head 4 side of a combustion chamber 18 is formed out of a part of conical surface 9, 10 extending approximately in a tangential direction from the seat surfaces of respective valves, centering respective intake valve seats 6 and respective exhaust valve seats 8. An ignition plug 17 disposed on the roof wall surface of the combustion chamber 18 is arranged facing the portion of the conical surface 9 on an intake valve side a little shifted from the center of the combustion chamber 18. By this, a combustion flame transmitting distance starting, centering the ignition plug 17 is designed so that it is shorter in the combustion chamber space on the intake valve side than on exhaust valve side. It is thus possible to make the combustion time on the intake valve side of weak swirl and the exhaust side of strong swirl coincide with each other approximately, providing the shortening of the total combustion period in the combustion chamber 18.

Title: Pressure sensor
Inventor: MORIMOTO HIDEO
IPC: G01L5/00
Filed: 1994-04-07
Abstract: PURPOSE:To obtain an electrostatic capacity type pressure sensor, in which response is hardly delayed and which is hardly brought into an uncontrollable state, by mounting a deformed electrode plate, a fixed electrode plate and an electronic device. CONSTITUTION:Since air is not used as a medium up to a pressure sensor in a pressure sensor, no response delay is generated. Since there is no air piping, an uncontrollable state due to leakage from the air piping is not generated, too. When a deformed electrode plate 1 is pushed in, the pressure sensor is elastically deformed, and electrostatic capacity between mutual deformed and fixed electrode plates 1, 2 is changed. The change of the electrostatic capacity is converted into an electric signal corresponding to the change of the electrostatic capacity by an electronic device 3. Accordingly, the force of pushing-in to the deformed electrode plate 1 can be output instantaneously as an electric signal corresponding to the force of pushing-in in the pressure sensor.
