Title: Diagnoses device in exhaust gas circulating device for internal combustion engine
Inventor: SHIMIZU HIROKAZU
IPC: F02D45/00
Filed: 1995-05-17
Abstract: PURPOSE: To prevent operability from being degraded owning to a diagnostic control by correcting ignition timing for cylinders having nothing to do with diagnoses in such a way that fluctuation in output for the aforesaid cylinders is restrained, while changing an exhaust gas circulating flow rate with an exhaust gas circulating control valve forcibly controlled for opening/closing, thereby judging whether or not an exhaust gas circulating flow rate is actually changed for diagonoses. CONSTITUTION: When the specified diagnostic areas of an internal combustion engine, that is, when engine revolutions, engine loading and cooling water temperature fall in the specified ranges of operating conditions, it is judged whether or not the engine is in a normal operating condition at a control unit 13, if it is judged YES, exhaust gas circulating flow is suspended with an EGR control valve 12 forcibly entirely opened. And at this time, change in pressure in the cylinder (combustion pressure) is detected by a cylinder inner pressure sensor 17, and the device is thereby diagnosed by judging whether or not change in an exhaust gas circulating flow rate matching to the aforesaid control is actually caused.  At this time, #2 through #4 cylinders excluding #1 cylinder concerned with diagnosis are delayed in angle for correction by a specified angle for ignition timing in order to cancel an increase in output torque caused by the suspension of exhaust gas circulating flow.

IPC: G06F17/50
Filed: 1994-05-31
Abstract: PURPOSE:To reduce the burdens of a designer by providing a means for automatically referring to an attribute file prior to input or output at the time of inputting or outputting design data. CONSTITUTION:When an operation for specifying the kind of input data is started by a pointing device 203, a CPU 204 automatically refers to the attribute file and displays a data input screen on a display device 205 and the designer selects an attribute to be inputted by the device 203. Then, a physical layer setting command is selected and the operation for specifying the physical layer of the input data is performed by the device 203. Then, the CPU 204 automatically refers to the file and displays the data input screen on the device 205. The designer selects the number of the physical layer to be inputted by the device 203 and finally, the design data are inputted by the device 203 and the prescribed design data are prepared. Thus, the designer classifies a logical layer and the attributes without depending on memory and performs design without being conscious of the matching of the logical layer and the physical layer.

Abstract: PURPOSE:To take-in clean air having no scattered tear mixed therein to inject the same, by providing a valve having an air suction port lower in air inflow resistance than an air jet nozzle to a compression chamber and providing an air suction port to the housing of a tonometer. CONSTITUTION:A rotary solenoid 1 rotates and a piston 4 advances to a position 4a to inject the air in a compression chamber 6 to the cornea Ec of an eye E to be examined from a nozzle 8 and, when the piston 4 begins to return to the original position, the compression chamber 6 becomes negative pressure. Hereupon, an one-way valve 10 is pushed by atmospheric pressure and overcomes the force of a return spring 11 to open. When the one-way valve 10 is opened, the open air is automatically sucked in the compression chamber 6 from an air suction port 12 lower in air inflow resistance than the nozzle 8. By this method, air reduced in the mixing with a tear can be injected at the time of the next injection of air.

Abstract: PURPOSE:To reduce noise to be generated due to the reproduction of a vertical time reinforcing signal. CONSTITUTION:After applying coring processing to a difference (P1-P2) between a sequential scanning signal P1 interpolated at its scanning line by using both of a main signal and a reinforcing signal and a sequential scanning signal P2 interpolated at its scanning line only by the main signal, the processed signal is added to the signal P2 to output the added signal. Thereby when the difference (P1-P2) is small, i.e., at the time of a noise level, the signal P2 including no reinforcing signal is outputted, obtaining a noise reducing effect. When the difference is large, i.e., at the time of a signal level, the signal P1 including no reflected distortion is outputted, so that a picture quality improving effect due to the reinforcing signal is not lost.
