While periphery or peripheries of workpiece(s) W lifted in floating fashion by simultaneous suction and expulsion of gas(es) between pair(s) of first and second, or upper and lower, transport stagesis/are retained by plurality of elevator pins, respective transport stage(s) is/are inverted vertically and workpiece(s) is/are transferred from upper first transport stage(s) to lower second transport stage(s) such that workpiece(s) W is/are lifted in floating fashion thereabove by simultaneous suction and expulsion of gas(es) in accompaniment to lowering of respective elevator pin(s) at said first transport stage(s).

Workpiece transport apparatus

A driving circuit which can drive an LCD apparatus without causing the residual image phenomenon is disclosed. The driving circuit has a polarity-inverting circuit for converting input video signals into polarity-alternating signals. The polarity-inverting circuit has input-output characteristics which are at least partially non-linear. The input-output characteristics are linear in the positive region, and non-linear in the negative region, or non-linear in the positive region, and linear in the negative region.

Driving circuit for producing varying signals for a liquid crystal

An improved process for producing a thin film magnetic head includes forming a nonmagnetic material layer over a lower magnetic core layer with an electrically conductive coil layer embedded in the nonmagnetic material layer. It further includes forming an upper magnetic core layer of a predetermined pattern by a specific method over the resultant to provide the thin film magnetic head.

Process for producing thin film magnetic head

There is disclosed a process for modifying in an oxygen plasma an inert reaction product produced on a Fe-Al-Si alloy back core during a production of a thin film magnetic head utilizing a reactive ion etching (RIE) process. As a result of modifying the reaction product it is made readily soluble in and thus removable by water.

Production of thin film magnetic head

There provides a process for preparing a coil type thin film magnetic head having high density record by planarization differences in level caused by an electroconductive coil holded between upper and lower magnetic cores.
