Title: Four-cycle engine
Inventor: MIZUMURA SAKAE
IPC: F02D13/02
Filed: 1990-10-18
Abstract: PURPOSE:To improve efficiency of exhaust gas purification by forming a secondary air supplying passage leading only to one exhaust passage for every cylinder, installing the passage close to an exhaust valve, and opening the exhaust valve corresponding to the exhaust passage earlier than other valves. CONSTITUTION:Under an operation of an engine, exhaust gas generated in the combustion chamber 83 passes through an exhaust gas passage 86 bringing about negative pressure conditions in secondary air supplying passages and a connection tube 213. Secondary air is then supplied from an air cleaner through a secondary air supplying tube, a lead valve 211, the connection tube 213, each of the secondary air supplying passages 212 to each of branched passages 86b. Then the secondary air reacts with combustible gas remained in exhaust gas immediately after exhausted from the combustion chamber 83, and combusted. Exhaust valve 90b corresponding to the branched passages 86b is opened a little earlier than other exhaust valves 90a. Combustible gas in the exhaust gas flowing into the branched passages 86a which are not form the secondary air supplying passages 212 is in contact to the secondary air in a collection part 86B, then reacts with the air for combustion because the collection part 86B of the adjacent branched passage 86 is heated to a high temperature.

Title: Home bus system
Inventor: NAKATANI TADASHI
Filed: 1984-12-28
Abstract: PURPOSE:To switch properly a circuit control system by putting a control code into a control word of a communication packet to switch the circuit control system. CONSTITUTION:A home bus system is usually set under a decentralized mode when communication controllers 1, 2 and 3 are operating in a CSMA/CD mode. Thus all terminals can use equally a transmission medium 10 to have communication with each other when necessary. In an emergency, the use is inhibited with the information transmission media of other terminals until a series of communications are through. In such a case, a code is set to the CW of a communication packet to switch the circuit control system. Then the circuit control system is switched to a polling mode from the CSMA/CD mode by general information.
