Title: Exhaust gas recirculation device of engine
Inventor: NODA KOJI
IPC: F02M35/10
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To enhance the distribution performance of EGR gas to cylinders in a engine having an intake system for distributing intake and supplying to the engine cylinders by means of branch passages branching from a collector. SOLUTION: An EGR gas introduction port 32 (32A, 32B) leading from an external recirculation passage is provided in an intake passage 23 upstream of a collector 24 so as to face in the tangential direction of the intake passage cross section. The plurality of EGR gas introduction ports 32 (32A, 32B) include a first introduction port 32A having a throttle passage part where the passage cross-sectional area decreases and a second introduction port 32B having no throttle passage part. EGR gas is injected at high speed into the intake passage by means of the throttle passage part of the first introduction port 32A to generate a strong spiral flow, this high-speed flow promoting the injection of the EGR gas from the second introduction port 32B. Thereby active airflow is generated in the intake passage whereby mixing of the EGR gas with fresh air can be promoted.

Title: Miss-fire deciding device for spark ignition type internal combustion engine
Inventor: NISHIMURA AKIHIRO
IPC: F02P17/12
Filed: 1991-11-26
Abstract: PURPOSE:To perform proper detection of a miss-fire through clear discrimination of a miss-fire from governing by detecting a specified abnormal frequency component, especially increased in case of a miss fire occurring, from a voltage signal corresponding to the number of revolutions of an engine and deciding that the miss-fire occurs when the abnormal frequency component exceeds a reference value. CONSTITUTION:In a spark ignition type internal combustion engine, the number of revolutions of an engine is constantly detected by a number of revolutions detecting means A and converts a detecting signal therefor into a voltage signal corresponding to the number of revolutions. From the outputted voltage signal, an especially increasing specified frequency component is detected as an abnormal component by an abnormal component detecting means B. Further, it is decided by a deciding means C that a miss-fire occurs when the detected specified frequency component exceeds a decision reference value. This constitution causes proper detection of the miss-fire through clear discrimination of the miss-fire from governing without being influence by unevenness between cylinders and a change with a time. Besides, the constitution eliminates necessity of a high performance computer and a complicated frequency analyzer and simplifies a miss-fire deciding device and reduces the cost thereof.

Title: Ceramic oscillator and production thereof
Inventor: ISHIBASHI KOJI
IPC: H03H9/13
Filed: 1990-11-30
Abstract: PURPOSE:To control thickness longitudinal vibration and to improve reliability by forming at least one of electrodes of flaky metallic powders as an essential component. CONSTITUTION:The electrode 3 which consists essentially of the flaky metallic powders 2 and is so formed with the powders as to superpose intricately on each other is provided on the plane part on one side of the piezoelectric ceramics 1 and the electrode 5 which is formed of spheroidal metallic powders 4 as an essential component is provided on the plane part facing the electrode 3. The electrode 3 formed by this constitution has the constitution in which the flaky metallic powders superpose intricately on each other. Since the flaky metallic powders 2 constituting the electrode 3 superpose intricately on each other, the thickness longitudinal vibration cannot escape to the outside when the thickness longitudinal vibration arises in the piezoelectric resonator. Only the thickness longitudinal vibration can be dispersed in this way without affecting the spreading vibration mode. The generation of the thickness longitudinal vibration is thus prohibited.

Title: Extruding nozzle for molding
Inventor: SAWAGUCHI TATSUE
IPC: B29C48/30
Filed: 1994-12-14
Abstract: PURPOSE: To quickly and efficiently degas unnecessary gas to be generated in a molded body by an extruding nozzle wherein contraction of a volume of a molding material having a large quantity of water content such as fine powders of chaff is strengthen by evaporating the water with heat so as to prevent the steam from working on a molding process as an unnecessary external force. CONSTITUTION: Fine powders of chaff 2 which are fed are guided to a molding section 4 being pressed by a guiding section 3. A cross-sectional area of a molding position 5 is smaller than that of the guiding section 3. The fine powders 2 are compressed forcibly by a pressing means and generate heat simultaneously with the contraction of the volume. The water content of the fine powders 2 evaporates with the heat and resides among the fine powders 2 as steam, so that the fine powders 2 are prevented from sticking to each other. However, as a degassing section 6 of the molding position 5 having a regular hexagon communicates with the atmosphere, the generated steam is not present in the compressed fine powders 2, but is discharged to the atmosphere from the degassing section 6. Accordingly, a molded body in which the fine powders 2 are sufficiently stuck together, strengthened without cracks and the steam in the molded body is removed and dried can be obtained from an extruding nozzle 1.

Title: Operation control device for ship engine
Inventor: TANAKA AKIRA
IPC: F02D31/00
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent an engine stall when an engine is switched from forward to reverse for braking by providing an intake quantity adjusting valve adjusting the intake quantity while a throttle valve is nearly fully closed and an intake quantity control means controlling the intake quantity adjusted by the intake quantity adjusting valve based on the state of an operation lever. SOLUTION: When a throttle valve 17 is opened, no feedback control is applied to an idle engine speed adjusting valve 60, the opening of the adjusting valve 60 is kept at the initial set value (opening to open 1/2, of a by-pass passage 61), and the normal operation corresponding to the throttle valve opening is continued. When the throttle valve 17 is fully closed and the lever speed of an operation lever 16 is larger than the set value at the timing immediately before reverse clutch-in, a computer judges that a hull braking action is taken, and it opens the idle engine speed adjusting valve 60 to control the engine speed to the brake engine speed. When the elapsed time after the braking operation becomes larger than the set value, the opening of the idle engine speed adjusting valve 60 is returned to the prescribed idling opening.
