Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To perform control to target stability even when a difference in an air-fuel error is present between an operation condition during non-establishment of a feedback control condition based on stability and a learning typical point. SOLUTION: An ignition timing and an air-fuel ratio during lean operation are respectively initialized by initializing means 21 and 22 such that margins from a stability allowable limit are equal to each other even when operation conditions are different from each other. Meanwhile, during non-establishment of a feedback control condition based on stability, an air fuel ratio leaning value is shifted to the rich side by a shift means 26 by a difference in an air-fuel ratio error between a current operation condition and a learning typical point, and an airfuel ratio initialized during lean operation is corrected by a correction means 27 by means of an air-fuel ratio learning value shifted to the rich side.  Thereby, in addition to a preceding application device, even when a difference in an air-fuel error is present between an operation condition during non establishment and a learning typical point, an air-fuel ratio is controllable to a target stability equivalent value.

Title: Suction device of engine
Inventor: ISHIKAWA YASUHIRO
IPC: F02B31/00
Filed: 1981-10-07
Abstract: PURPOSE:To reduce a combustion pressure and reduce the striking noise of gears by slightly opening an open/close valve which is placed in a high load suction passage when an engine is idling. CONSTITUTION:A low load suction passage 11 and a high load suction passage 12 are laid independently from each other in the vicinity of a suction port 9 which opens to a combustion chamber 7 of an engine. In idle running, with a low load throttle valve 22 almost fully closed, negative pressures from primary and secondary negative pressure take-out openings 17 and 18 are led into a negative pressure chamber 16d of a diaphragm device 16. An open/close valve 13 in the high load suction passage 12 is thereby opened to a minimal degree to decelerate the velocity of a suction air which flows into the combustion chamber  7, hence easing a swirl therein. Since a combustion pressure is reduced and the fluctuation of an angular speed of a crank is thereby moderated, a striking noise of gears may be reduced.

Title: Automatic varied-angle controller for electrically driven remote control mirror
Inventor: SAITOU KUNIHIRO
IPC: B60R1/06
Filed: 1982-09-17
Abstract: PURPOSE:To improve operation performance and safety when a car is put into a garage by permitting automatic angle-change of a mirror to a prescribed position only by setting a speed change gear to back position and putting the mirror into standstill state and allowing the mirror to be restored to the original position through the return operation to the neutral position. CONSTITUTION:When a speed-change gear is operated to back position and a switch SW1 is turned ON, OR circuits OR2, OR1, OR5, and OR4 are set in H, and motors ML and MR are brought into conduction, and right and left mirrors are angle-changed downward, and when the mirrors angle-change to a prescribed position, limit switches SW2 and SW3 are turned ON, and the mirrors stop. When the speed-change gear is returned to the neutral position after the completion of putting car into a garage, the switch SW1 is turned OFF, and each output of the OR circuits OR1 and OR4 becomes ''H'', and motors ML and MR are brought into conduction, and the right and left mirrors start restoration to the upward direction. At this time, limit switches SW2 and SW3 are turned OFF, and counters 4a and 4b count down each holding count to zero, and conduction is suspended, and the right and left mirrors return to eye point and stop. Thus, backward operation such as putting car into garage is facilitated.

Title: Surface machining method
Inventor: TANAKA KUNIO
IPC: B23Q15/00
Filed: 1985-07-20
Abstract: PURPOSE:To shorten the tool path by obtaining the cross-point between an offset curve at the outside of closed curve and the cutting path thus obtaining the coordinates of the outermost point between a cross-point with next cutting path and moving the tool untill matching with said coordinates. CONSTITUTION:Assuming Pi, Qi are the cross-points between an offset curve OFC' or a closed curve CCL added with excess metal thickness, clearance and the tool diameter and the cutting path PTi at the starting ending sides of machining, the cross-points Pi+1, Qi+1 with next cutting path are obtained. Then the coordinates of the outermost point Ri of curve OFC' between the cross-points Qi and Qi+1 in the cutting path direction are obtained. The tool TL is moved along the cutting path PTi untill the positional coordinates of tool in the cutting path direction will match with the coordinates of the point Ri to perform surface machining. Said operation is repeated to perform regional machining. With such operation, a closed curved face can be machined completely resulting in shortening of tool path and the machining time.

Title: Magnetic type encoder
Inventor: MIYATA TOSHIHARU
IPC: G01D5/245
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To enhance the resolution of a magnetic type encoder by a simple method and the achieve a high accuracy in measurement. SOLUTION: A highly permeable magnetic material 15, which forms a regular pattern along the moving direction of a detecting part, is applied in a magnetic- flux generating part, which generates the uniform magnetic flux in the moving range of the detecting part, and the planar part of a scale 11 between the magnetic-flux generating part and a magnetic sensor. Thus, the position information of the scale 11 is recorded by the change in magnetic flux density. When respect to the change in magnetic flux toward the magnetic sensor, all the surface of the scale 11 has the same polarity. Therefore, even if the pitch of the scale 11 is miniaturized, the reduction of the magnetic flux caused by the diatance from the surface of the scale 11 can be suppressed. Therefore, the pitch of the scale 11 can be miniaturized readily by already-existing thin-film technology. Thus, the resolution of the encoder can be enhanced.

Filed: 1989-06-23
Abstract: PURPOSE:To accurately detect whether paper is left or not on a paper tray by providing constitution in such a way as projecting light from a light emitting element through a through hole, provided in the paper tray, into a residual paper-detecting light receiving element so as to detect the paper not present, when it is not left on the paper tray. CONSTITUTION:In a condition that paper 70 is not present on a paper tray 54, light from a light emitting element 60 is transmitted to pass through a through hole in the paper tray 54 and projected into a residual paper-detecting light receiving element 65. However, when the paper 70 is left present on the paper tray 54, the light from the light emitting element 60 is intercepted by the paper 70 and not projected into the residual paper-detecting light receiving element 65. As a result, presence/absence the paper can be accurately detected with no influence by dispersion of a set position of the paper tray 54.
