Title: Structure of combustion chamber and combustion method of engine
Inventor: YAMAMOTO HIROYUKI
IPC: F02P13/00
Filed: 1991-09-20
Abstract: PURPOSE:To remarkably decrease quantites of NOx and HC, especially NOx. CONSTITUTION:A plural number of ignition gaps G1-G4 are arranged at spaces on the line which passes the approximate center of a combustion chamber 1 and extends in radial direction of the combustion chamber 1. Flame faces of air-fuel mixture ignited at the respective ignition gaps G1-G4 are circularly spread from the centers of the respective ignition gaps G1-G4 at first. The respective flame faces spreading from the centers of the respective ignition gaps G1-G4 are mutually collide at the time of t4, and a burnt zone (a) (hatching part) which slimly extends across the whole length in radial direction of the combustion chamber 1 is formed, and the flame faces are formed in approximate column shape. The flame face is spread in the direction approximately perpendicular to the arrangement direction of the ignition gaps G1-G4 after the time (t4). Increase in a combustion rate is suppressed by collision between the flame faces at the time of (t4), and thereby a combustion rate is approximately equalized for the whole combustion period.

Title: Demultiplexer/multiplexer and demultiplexing/ multiplexing method
Inventor: KUNISHIMA HITOSHI
IPC: H04L69/14
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a demultiplexer/multiplexer that automatically re-executes detection of a delay correction amount. SOLUTION: At restoration of power after its interruption, a re-execution signal generating circuit 221 outputs a re-execution signal to a demultiplexer/ multiplexer circuit 21, and the demultiplexer/multiplexer 21 transmits the re- execution signal to an opposite demultiplexer/multiplexer 20 without demultiplexing the re-execution signal. A re-execution signal detection circuit 233 of the opposite demultiplexer/multiplexer 20 detects the re-execution signal from a re-execution detecting circuit 233 and a delay detection signal generating circuit 222 re-transmits a delay detection signal.  Upon the receipt of the delay detection signal sent from the opposite demultiplexer/multiplexer 20, the demultiplexer/multiplexer 20 uses a delay detection signal detection circuit 232 detects again a transmission delay with respect to each channel and a delay correction circuit 231 sets a delay controller amount again.

Filed: 1987-10-27
Abstract: PURPOSE:To enhance the preciseness of an electron emitting part forming position and secure wide versatility for a surface conductive electron emitting element by performing formation of the electron emitting part and supply of emission current by the sue of each electrode. CONSTITUTION:A film 8 consisting of metal, semiconductor, etc., is formed on a base board 5. A conductive metal is laminated on the two ends of this film 8 so as to form electrodes 1, 2. The central neck of the film 8 is heated by performing current supply between these electrodes 1, 2, which forms an electron emitting part 4, whose position is defined by the use of specified electrodes 1, 2, and there is no risk of formation unnecessarily in other parts. Then electrodes 6, 7 for supply of emission current are formed by lamination of conductive metal on the two sides of the electron emitting part 4. These electrodes 6, 7 cover the other parts of the film deteriorated by current supply to enable driving with a low voltage. This raises the degree of freedom for the shape of film 8 and increases versatility.
