Title: Method for monitoring emission of nitrogen oxide from internal combustion engine
Inventor: JIYANNRUI MANE
IPC: G01M15/10
Filed: 1991-09-26
Abstract: PURPOSE: To immediately measure discharge of nitrogen oxides from an internal combustion engine on a site and to provide a simple, low cost and firm measuring device. CONSTITUTION: An accelerometer is installed to one of the members that partition a combustion chamber in an engine and the engine is operated under various loads or speeds. A signal of the accelerometer, a measured quantity of nitrogen oxide NOx included in an exhausted gas and data in relation to characteristic parameters of the operation of the engine including at least a speed, load and an air temperature at a cylinder inlet are recorded simultaneously. A relationship between the measured quantity of the nitrogen oxide and the characteristic parameter of the signal of the accelerometer is determined and an accelerometer is installed to an engine to be monitored under the same condition and characteristic parameters thereof are recorded simultaneously. An equivalent value of discharged nitrogen oxide by the engine to be monitored is determined, based on the relationship.  The judgment in terms of a countermeasure to be taken for observing a set value imposed for the discharge of nitrogen oxide is adequately made.

Filed: 1991-09-27
Abstract: PURPOSE:To obtain a high order overtone quartz oscillator by extracting particular oscillating energy of the main electrode on the quartz plate to the subelectrode by means of acoustic matching and by consuming the extracted particular oscillating energy for a load damping impedance. CONSTITUTION:On the surface of an AT-cut quartz plate 4, exciting electrodes consisting of a main electrode 1 and lead electrode 3 and subelectrode 2 are disposed separately from each other. Further, at the resonance frequency that should by suppressed, the electrode 1 and electrode 2 together constitute the acoustic coupling filter of bandpass type. At the same time, at a desired resonance frequency, in order not make the resonance frequency of electrodes 1 and that of electrode 2 coincide with each other so as to make both electrodes into an unmatching state, the distance between both electrodes 1 and 2 is appropriately set and also both electrodes are prepared differently in thickness and dimensional size. Furthermore, a subelectrode 2 is connected to and loaded with a damping impedance 5. With this, at a particular resonance frequency, the resonant oscillation can be suppressed selectively with respect to frequency, and at a desired resonance frequency the quartz oscillator that can oscillate in terms of selective frequency can be obtained.

Filed: 1994-10-18
Abstract: PURPOSE: To measure the outer diameter of steel pipe, etc., with high accuracy by a simplified apparatus by calculating based on the number of detected bits and the distance between supporting bodies. CONSTITUTION: Supporting bodies 4 and 4 are elevated depending on the outer diameter of a steel pipe P by the rotation of a ball screw 6 driven by a motor 7, and they are positioned in such a way that a line connecting laser projectors 8 and 8 and one-dimensional line sensors 9 and 9 may pass the upper and lower end parts of the steel pipe P. Next, while a disc face-plate 11 is turned 180 deg. at the axial center of the pipe P as center O, a projector 8 directs a laser light toward the sensor 9. A part of the laser is blocked by the pipe P, a laser with widths of A and B is projected on the sensors 9 and 9, then the number of corresponding bits is inputted into a calculation processor 13.  On the other hand, the distance between the bodies 4 and 4 that is measured by a linear encoder 10 is inputted into the processor 13 and the processor 13 calculates the outer diameter of the pipe P based on the number of bits and the distance between the bodies 4 and 4. Thus, the outer diameter of steel pipe, etc., with large diameter can be measured with high accuracy.

Abstract: PURPOSE:To attain high speed operation (processing) by providing a coefficient device multiplying a code length of a code not decreased and a coefficient decided as a source element of a source polynomial and the code length of the decreased code in advance as each coefficient of an error location polynomial. CONSTITUTION:A code length (n) of a code not decreased and a coefficient alpha<(n-n''+1)j> decided by a code length n' of the decreased code are multiplied as each coefficient sigmaj of the error location polynomial obtained in advance by coefficient devices 41-44 and its output is preset by plural m-bit parallel latches 1-4. The (n'-1) times of shift is repeated by m-bit parallel latches 1-4 from the preset state, all latch outputs and '1' are added by an adder 9 and its output is decided by an input zero decider 10. When the result of decision is zero, a code error takes place at the location of a received word and when the result of decider is not zero, no code error exists. Thus, the actual code error location is obtained from the error location number alpha<-i> obtained in this way, and the error number is obtained to execute the code error.

IPC: F16H9/18
Filed: 1990-10-15
Abstract: PURPOSE:To improve durability by providing a pulley on the driven side with a fly weight to perform gradual flow-out of a lubricant and a cam mechanism on the driven side to energize the pulley on the driven side in a direction, in which width is decreased, according to the magnitude of load torque. CONSTITUTION:When the number of revolutions of a pulley 5 on the driven side is increased, a centrifugal force exerted on a fly weight 50 is increased, a guide 46 having a slope 46a with which the fly weight 50 makes contact is axially pushed, and a moving pulley 16 is forced to approach a stationary pulley 14. As a result, the fly weight 50 is slid from the position in an initial rotation state to the position in a high speed rotation state as it is rolled along the slope 46a of the guide 46. Since the fly weight 50 holds grease in a counter sunk part and has a hole 54 communicated with the outside, when the fly weight 50 is rolled over the slope 46a of the guide 46, the grease is fed to the slope 46a of the guide 46 through the hole 54 by means of a centrifugal force exerted on the grease held in the counter sunk part.

Filed: 1987-11-02
Abstract: PURPOSE:To enable use in a light Q damp state without using any isolator by providing a comparing circuit which compares a reflected wave voltage and 1/N of a traveling wave voltage. CONSTITUTION:A directional coupler 2 is connected to the output side of a transmitter and its traveling wave component is detected by a traveling wave Pf detector 4. Its DC detection output is divided to 1/N through a voltage divider 8. Then the reflected wave component from the coupler 2 is detected by a reflected wave Pr detector 7 and by the comparing circuit 9 the 1/N output of the traveling wave detection output and reflected detection output are compared. When the latter voltage becomes higher than the former voltage, the generated voltage of a reference voltage generator 6 is controlled with their difference output. Consequently, the transmission output of the transmitter 1 is stabilized under the control of an automatic power controller 5. Further, a PIN diode 11 is put in operation with the output of the comparing circuit 9 and a Q damping resistance load 10 is closed to stability the transmission load.
