摘要： An optical card recording and reproducing device including an optical head for emitting a light beam spot to the optical card having a plurality of parallel data tracks to which data is recorded; a transfer system for transferring the optical card and/or the optical head; and a track number confirmation means for confirming the track number recorded in the address data area in the data track of the optical card. The optical card recording and reproducing device also includes a transfer stopping means for stopping the optical head when an incorrect track number is deleted. The system minimizes the relative transfer distance between the optical card and the optical head, and at the same time, the total relative transfer distance of the optical card and/or the optical head when confirming the track number more than twice. Thus, the total time required for track number confirmation can be greatly shortened.

摘要： An electronic throttle valve opening control system provides an actuating D.C. motor for opening or closing the throttle valve and a control circuit for controlling the D.C. motor current in response to the difference between the detected real throttle valve opening and a target value of the throttle valve opening. In addition to the above difference signal, the D.C. motor is controlled by a first correction quantity signal in accordance with variation of the detected throttle valve opening and a second correction quantity signal in accordance with the friction force existing in a valve opening control mechanism.

摘要： A method of and a photomask for manufacturing an optical memory element. The manufacturing method includes the steps of: subjecting a positive type photoresist coated on a glass substrate to exposure, by using the photomask capable of irradiating light onto a portion of the photoresist other than the remaining portion, for forming pits on the glass substrate such that the portion of the photoresist is solubilized against developing solution; developing the photoresist by using the developing solution so as to remove the portion of the photoresist; and etching the glass substrate so as to directly form, as convex portions, the pits on a surface of the glass substrate.
