Filed: 1994-03-10
Abstract: PURPOSE:To prevent the increase of an NOX discharge amount after warming up and to improve engine stability by a method wherein a target value of a control factor during operation in a lean combustion state is changed by an engine water temperature. CONSTITUTION:When an engine water temperature Tw exceeds a given water temperature Twl# at S21 and a lean condition is set at S22, a map air-fuel ratio Mdml is determined at S23 by referring to a lean air-fuel ratio map MDMLL. A water temperature correction air-fuel ratio Twdml (which is increased with the increase of the engine water temperature Tw) computed from the engine water temperature Tw is subtracted to determine a target air-fuel ratio correction factor Tdml at S25.

Title: Diagnostic unit for rotary machine
Inventor: NAGAI ISAO
IPC: G01M99/00
Filed: 1980-03-26
Abstract: PURPOSE:To arrange so that a correct spectrum amplitude value may be obtained and real-time processing be made at site by analyzing a spectrum under FFT method and carrying out an evolution of the sum of square on a forward or a backward amplitude value centering around an elected amplitude value. CONSTITUTION:An output from an oscillation detection device 1 installed on a rotary machine passes through a filter 2 which removes a frequency component not necessary for the diagnosis of an abnormality and then is converted to an alternate or a direct current or vice versa 3. After this process, arithmetic operation is carried out on a spectrum distribution by means of a FFT-system spectrum analyzer 5 and a spectrum amplitude value is given to an amplitude magnitude distinguishing unit 5 and a sum of square evolution operator 6. The distinguishing unit 5 selects a meaningful amplitude value from among amplitude values which are output every frequency which is an integer time as much as a decomposition frequency set by an analyzer 4. While the operator 6 carries out a required sum of square evolution operation using as a base for judgement a large amplitude value selected by the distinguishing unit 5. As a result, it is possible to obtain an oscillation spectrum of the rotary machine in the form of a linear spectrum.

Title: Temperature detecting circuit
Inventor: IWAMOTO MITSUMASA
IPC: G01K7/24
Filed: 1978-04-07
Abstract: PURPOSE:To improve the performance of an integrated temperature detecting circuit by using the difference in temperature characteristics between two diodes or transistors as temperature detecting means. CONSTITUTION:A temperature detecting circuit is constructed to include temperature detecting diodes 211 and 212, FETs 213 and 214 and an operational circuit 215. The potential Vo at the output terminal 216 of the detecting circuit is varied with the rate of the currents flowing through the FETs 213 and 214. As a result, if the two FETs have beta1 and beta2 as beta, the potential Vo is controlled in accordance with the ratio of beta2/beta1 but is not dependent upon the variation in the voltage  variation and variation in the threshold voltage value. In other words, the variation  due to the fluctuations between the elements as the IC circuit can be eliminated.  Transistors may be used in place of the diodes. Thus, it is possible to produce an  integrated circuit which is free from the variation due to the fluctuations of the  elements.
