Title: Exhaust system of internal combustion engine
Inventor: TAKEYAMA MASAKI
IPC: F01N13/00
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent an oxygen sensor from being deteriorated by dew that forms in an exhaust pipe of each cylinder of a multi-cylinder internal combustion engine. SOLUTION: At a portion 8 at which an exhaust pipe 1 from each cylinder meets others from other cylinders to form a main exhaust pipe 2, an end of the exhaust pipe 1 is cut slantways to form a slant edge and that slant edge is bent inward toward an upstream side to form a slant guide groove 1b on the inside of an lower end of the exhaust pipe 1. Dew is properly trapped by the guide groove 1b, guided along to a bottom portion 1c, and drop to a particular point along a wall surface of the main exhaust pipe 2. If holes 6 are made in a cover 5 of an oxygen sensor 4 at any point other than this particular point, therefore, it effectively prevents dew from entering through the holes 6. The mere formation of the slant edge without providing the guide groove 1b ensures that most of dewdrops travel along the slant edge, dropping to the particular point. Changing the direction in which the slant edge is formed will also ensure that dewdrops drop at a center of the main exhaust pipe 2.

Title: Deterioration detecting device for catalyst for purification of exhaust
Inventor: YAMAGUCHI MASAHIKO
IPC: F01N11/00
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To conduct determination of catalyst deterioration at favorable precision while improving exhaust purifying efficiency. SOLUTION: Sensors for detecting an air-fuel ratio of exhaust gas or if it is rich or lean are respectively installed on the upstream side and the downstream side of catalyst for purifying exhaust, and sub-feedback(sun-F/B) control for reflecting output of the downstream side sensor on air-fuel ratio feedback control is conducted. As catalyst deterioration determination executing conditions are satisfied, a gain of an integration term and a skip term of a sub-F/B correction coefficient is changed into a large valve, so if deterioration of catalyst exists or not is largely reflected on the output of the downstream side sensor.  In the case of the catayst being normal, the amplitude and frequency of the output of the downstream side sensor are not so much enlarged even when the gain of the sub-F/B correction coefficient is changed into the large valve, but in the case of the catalyst being deteriorated, the amplitude and frequency of the output of the downstream side sensor are relatively largely increased. By making relative evaluation of the output of the downstream side sensor to the reference of output of the upstream side sensor, if deterioration of the catalyst exists or not can be determined at favorable precision.

Title: Outdoor unit for refrigerator
Inventor: UESUGI HIDESHI
IPC: F16F15/08
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To suppress the coupled vibration generated due to the rotations of a plurality of blowers without altering the use of the components of fans or motors by increasing the length of the leg of the suspension support member of a drive motor to longer than the leg of the suspension support member of the other drive motor. SOLUTION: Since the supply voltages to drive motors 1 are the same, the numbers of revolutions of three propeller fans become substantially the same. However, since the leg of the member 4a of the suspension support members 4 and 4a is longer, the vibration responses to the numbers of the revolutions do not become uniform because the right, left and the center intrinsic frequencies of a vibration system including the members are different. That is, the individual vibrations propagated from the members 4 and 4a to an upper surface panel 5 do not become large vibration amplitude even by the superposition of the vibrations.
