Test points are connected in parallel to shift registers which are read out bidirectionally. Comparisons are then made of the data in each direction of shift and inconsistencies of the compared signals, from a reference data signal, cannot only indicate which test point has an error present thereat, but whether and which stage of a shift register employed in the present diagnostic system is inoper...

PURPOSE:To obtain strong bonding by a method wherein a layer of polymer grains, granules or pellets is placed, a layer of ultrahighmolecular polyethylene grains or granules is provided on the above-said layer and is heated and pressed at the melting point or above of crystals of the ultrahighmolecular weight polyethylene. CONSTITUTION:A layer of polymer grains, granules or pellets is placed and o...

PURPOSE:To convert electrical energy given to a piezoelectric element effectively into rotational energy by arranging the piezoelectric element between rotating plates and generating progressive vibrations by the piezoelectric element so that the rotating plates are turned. CONSTITUTION:A piezoelectric motor 1 contains a true circular cylindrical housing 3 with a ceiling section 2 and a bottom pla...

A slide-hinged, turnable window has the window casement (10) pivotably mounted about first upper and lower pivot pins (12) which via their respective slides are connected to their respective guide members (20) on the frame. The casement is also pivoted about second upper and lower pivot pins (14) at the outer ends of pivot arms (23) pivoted on the window frame (11). The pivots are easily releasabl...
