20160115895 | CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - An object is to improve the combustion condition in an internal combustion engine equipped with a supercharger and performing diesel combustion using fuel having a relatively high self-ignition temperature in an operation state in which the engine load is increased or decreased. A control apparatus performs first injection during the compression stroke, causes spray guide combustion to occur, and starts to perform second injection at such a second injection time that combustion of injected fuel is started by flame generated by the spray guide combustion, thereby causing self-ignition and diffusion combustion of fuel to occur. During a response delay period in changing the boost pressure when changing the engine load of the internal combustion engine to a target engine load, the ratio of the quantity of fuel injected by the first injection to the total fuel injection quantity in one combustion cycle is made higher than the ratio of the quantity of fuel injected in the first injection to the total fuel injection quantity in one combustion cycle during the time when the engine load is equal to the target engine load and the actual boost pressure is equal to a target boost pressure corresponding to the target engine load. | 2016-04-28 |
20160115896 | FUEL INJECTION DEVICE - When a main injection is performed, a first timing that is a time earlier than a second timing is selected as the valve opening starting timing, and a first period that is the period of time shorter than a second period is selected as the control period. Also, when a pilot injection is performed, the second timing that is the time later than the first timing is selected as the valve opening starting timing, and the second period that is the time longer than the first period is selected as the control period. Thus, in an injector with increased valve opening responsiveness, the valve opening behavior of a control valve of the injector in fuel injection with a minute injection quantity can be stabilized without replacing a control device, particularly an EDU with that of a large current specification. | 2016-04-28 |

20160115987 | FIXTURE FOR A VEHICLE - A fixture for a vehicle, which is configured so that three retaining arms inserted into and caught by a coupling hole formed in a body panel are inserted into and caught by the coupling hole to be spaced at regular intervals from each other, and arranged in the form of a triangular pyramid so as to absorb an external force, even though the external force is applied in any directions, thereby being easily assembled, and which is capable of dispersing and absorb twisting generated when an indoor handle installed using the fixture is used, and thus being prevented from escaping from or being separated from the coupling hole. | 2016-04-28 |
20160115988 | SCREW WITH A SCREW HEAD WHICH HAS A DRIVE - A screw with a screw head which has a drive that includes cams that are formed by recesses introduced around the cams. The cams are used to transmit torque, in which, on the cam end facing the screw head, a cam has a cam head surface inclined with respect to a plane that extends perpendicular to the screw axis. The radial extension of the cams is arranged and designed such that the cams centre a tool introduced into the screw drive. The cam head surface has a first surface and a second surface, each of which is inclined in its respective rotational direction and which intersect each other in an intersection line. | 2016-04-28 |

20160115990 | ANTI-LOOSENING CYLINDRICAL THREADED PART - An anti-loosening cylindrical threaded part includes internal and external threaded part. A cylindrical internal thread is arranged in inner hole of internal threaded part a cylindrical external thread is arranged on a screw of external threaded part, the inner hole of internal threaded part has cylindrical surface parallel to a longitudinal center axis of internal thread, and an inner diameter of cylindrical surface is greater than minimum inner diameter of internal thread. Surfaces of internal and external thread and cylindrical surface are not covered with anti-loosening materials. After internal and external thread are mutually screwed, cylindrical surface and a crest of external thread are mutually close contact structures, that is, a horizontal locking structure; therefore, loosening can be effectively prevented between cylindrical internal and external threaded part without longitudinal contractility of threaded part and a workpiece, and presently suitable for loosening prevention in various connections of the cylindrical threaded parts. | 2016-04-28 |
20160115991 | CONNECTING ASSEMBLY AND CONNECTING DEVICE - A connecting assembly includes a first pipe, a second pipe and a connecting part. The connecting part includes a spherical rotating portion. The second pipe includes a connecting portion. The connecting portion includes two clamping parts and defines a sliding groove. The rotating portion is received between the two clamping parts. The connecting part rotates around the spherical rotating portion. The connecting part moves along the sliding groove. The first pipe is rotatably connected to the second pipe. | 2016-04-28 |
