Inventor: TSUKAMOTO OSAMU
IPC: G01C3/06
Filed: 1991-07-26
Abstract: PURPOSE:To detect exactly a shift of the rotational position of an optical distance sensor. CONSTITUTION:Measurement of a distance in the direction of the optical axis is executed for a reference sample 9 set on a table with the fall line of a slanting surface pialigned with the axis Y, by a distance sensor 5a which can be rotated around a vertical axis V while an angle theta formed by the axis V and the optical axis L is held unvaried, and a value thus obtained is stored as a first measured value Q1. The table being moved by Z in the vertical direction thereafter, measurement of the distance is executed again and a second measured value Q is stored. Based on the amount Z of movement, the first measured value Q1, the second measured value Q and the value of the formed angle theta, a distance DELTAZ in the direction of the axis V from a point PO of intersection of the axis V and the slanting surface pi to a light sensing point P2 at the time of detection of the second measured value is determined by an equation DELTAZ=Q.costheta-(QZ)/(Q-Q1), and based on DELTAZ and a tilt angle alpha of the slanting surface pi, a distance DELTAY in the direction of the axis Y from the light sensing point P2 to the point PO of intersection is calculated by an equation DELTAY=DELTAZ/tantheta. Based on the distance DELTAY and a distance Q.sintheta of projection to the table by the second measured value Q, moreover, a shift angle gamma of the optical axis L to the axis X is determined by an equation gamma=sin<-1> (DELTAY/Q.sintheta).

Abstract: PURPOSE: To check any drop in sealability between a case and a seal ring as well as to prevent any pressurized air from flowing into a center housing with certainty. CONSTITUTION: At the inner circumferential side of a thrust bearing 6 holding a shaft 2 of a supercharger, a collar thrust 7 is installed there, and one end of a seal ring 9 is installed in the one end in a state of being contacted, while this seal ring 9 is housed in a retainer 11.

Abstract: PURPOSE:To protect an apparatus by preventing the erroneous insert and discharge of a cassette, by providing an erroneous operation preventing lever for limiting the operation of a lock lever engaging the cassette in a freely detachable manner. CONSTITUTION:Recording paper 12 is wound around the outer periphery of a drum 13. When the recording paper 12 reaches a recording start position, the drum 13 is stopped and a recording head 19 is raised to be contacted with the recording paper 12 under pressure through a transfer sheet 16. At this time, a lock lever 22 is engaged with the notch part of a cassette 21 to fix the cassette 21 to a predetermined position in the axial direction and, because the lock lever 22 is also engaged with the notch part of an erroneous operation preventing lever 23, said lock lever 22 can not be moved. Therefore, the cassette 21 is always fixed to a predetermined position. When recording operation is completed, the recording head 19 is fallen to push down the erroneous operation preveting lever 23 through a pin 26. Therefore, the engagement of the lock lever 22 and the erroneous operation preventing lever is released to enable the discharge of the cassette 21.

Title: Knock control system for internal combustion engine

Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To improve the reliability in each amplification factor by adsorbing each individual tolerance in three amplifier circuits to be switched to get a signal available in knock control, without using a highly accurate circuit element. SOLUTION: When two of the A/D converted values converted by an analog- to-digital converter 21 corresponding to signals out of three x1, x4 and x16 amplifier circuits 13, 14 and 15 are within the normal specified range being compensable together, the analog-to-digital converted value of the signal out of the switched amplifier circuit is compensated.  With this constitution, even if each amplification factor of these three amplifier circuits is shifted from the viewpoint of design due to tolerance of respective circuit elements, the A/D converted value of the signal out of the switched amplifier circuit is compensated by a ratio calculated on the basis of the A/D converted value by the analog-to-digital converter 21, so that reliability in each individual amplification factor of these three amplifier circuits is well improved, and thus continuity in knocking control hereafter is compensable.
