IPC: F02D41/14
Filed: 1990-08-04
Abstract: PURPOSE:To improve purifying efficiency by a catalyst by controlling a fuel injection amount to be adjusted based on a predetermined frequency and amplitude with a feedback study correction amount, stored at normal operation time, serving as the center when an air-fuel ratio measuring means is in trouble. CONSTITUTION:In a control circuit 16 during operation of an engine, output signals of various sensors are input to calculate collectively a correction coefficient of water temperature, intake air temperature, air-fuel ratio sensor, etc., and a basic fuel injection amount of the base from an intake air amount per 1 cylinder in an interruption program, and this amount is corrected by a correction coefficient, calculated by a main program, to calculate the actual injection amount and to drive-control an injector 4. Here, a value of the feedback correction coefficient is set to a value such that it is alternately changed with a predetermined value serving as the center in predetermined period and amplitude by an air-fuel ratio sensor output timer, when an air-fuel ratio sensor 8 is decided in trouble. In this way, air-fuel ratio is vibrated in predetermined amplitude in the vicinity of the theoretical air-fuel ratio to improve purifying efficiency of a catalyst.

Title: Switching control system
Inventor: OHARA KATSUICHI
IPC: G06F11/20
Filed: 1991-07-24
Abstract: PURPOSE:To constitute the system with the minimum number of signal lines by unnecessitating connection from a control unit to a unit to be controlled individual signal lines by transmitting the switching request signal of the own station to the control unit with each unit to be controlled according to a time slot allocate signal. CONSTITUTION:An (n) pieces of units 2-1-2-n to be controlled are connected to a control unit 1, and a time slot allocate signal (1) is impressed from the unit 1 to the units 2-1-2-n. The units 2-1-2-n receiving this signal (1) transmit a switching request signal (2) to the unit 1 at a time slot when detecting the time slot allocated to the own station. Thus, since the switching request signal is loaded with time division and impressed to the control unit 1 at the respective units to be controlled, only the signal line for the time slot allocate signal (1) and the signal line for the switching request signal (2) are enough for this system.

Title: Optical pressure sensor
Inventor: MIYAZAKI JUNPEI
IPC: G01L7/04
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To provide an optical pressure sensor capable of remote measurement and free from malfunction due to electromagnetic induction, and does not need a power source in a sensor part. SOLUTION: In this optical pressure sensor, when a pressure to be measured in a Bourdon-tube 8 changes, an interval between the free end 81 side and the fixed end 82 side of the tube 8 changes. As a result, an optical fiber strain sensor 71 fixed between the free end side and the fixed end side of the tube is elastic. Displacement of the optical fiber strain sensor 71 is in proportion to a pressure to be measured, and not affected by electromagnetic induction, so that mulfunction does not occur. Since a power source is unnecessary, a strain signal of the sensor can be transmitted to a remote place through optical fibers 1a, 1c, and remote operation is enabled.

Title: Precise finishing method with grinding wheel overlapped with supersonic and low frequency vibration
Inventor: KUMABE JUNICHIRO
IPC: B24B1/04
Filed: 1986-09-04
Abstract: PURPOSE:To reduce the grinding force, by vibrating a grinding wheel in the rotary direction with low frequency while simultaneously vibrating in axial or radial direction with supersonic vibration thereby cutting chips finely and reducing the average grinding temperature rise. CONSTITUTION:Low frequency vibration 23F, A is applied in the rotary direction while supersonic vibration of frequency (f) and amplitude (as) is also applied in the rotary direction 34 onto a grinding wheel 35 an the circumferential speed V of said grinding wheel 35 is increased so as to grind a work 2 with the circumferential speed v. Consequently, the cutting length on a grinding face is minimized while the cutting depth in abrasive grains is varied intermittently so as to crush the chips finely thus producing a short period pulsating grinding force waveform having low pulsating grinding force. The pulsating grinding force waveform will be a heat pulsating waveform and does not heat the grinding face. Furthermore, a grinding mechanism for smoothing the grinding face through low frequency vibration in the direction of the grinding wheel while crushing the chips finely is additionally provided so as to smooth the surface.

Title: Measuring method of dynamic frictional characteristics of electrostatically chargeable film
Inventor: TATSUNO TETSUO
IPC: G01N19/02
Filed: 1983-11-07
Abstract: PURPOSE:To correct an error in measurement of a coefficient of dynamic friction due to the charging of an electrostatically chargeable film by measuring variation in tensile strength of the film at one terminal while applying tensile strength which varies continuously to the other terminal side of the film. CONSTITUTION:A tape 1 contacts the surface of a cylinder 2 at a holding angle theta=90 deg. and the cylinder 2 is rotated as shown by an arrow. Simultaneously, the tensile strength T1 which varies continuously is applied to the tape 1 at the side of a measuring instrument 3 in the rotating direction and variation in tensile strength T2 is measured at the side of the other measuring instrument 4. The measured tensile strengths T1 and T2 are compared with each other by a computing element 5 to calculate a coefficient muK of dynamic friction and charging force sigma. Then, the relation between the T1 and T2 at two points between which the contacting body is present is calculated with those two coefficients muK and sigma as a mathematical expression. This relation allows the accurate coefficient of dynamic friction of the tape 1 to be measured speedily even when the charging performance of the tape is high. Those data are utilized to perform high-level speed control.
