Title: Printing type belt moving apparatus
Inventor: TOKUNAGA HARUHIKO
IPC: B41J1/20
Filed: 1983-06-29
Abstract: PURPOSE:To prevent a printing type belt from being undersirably raised by a printing operation, by retaining a pulley in such a manner that a crown is below a balancing position where the upward and downward radial compliances of the pulley balance with each other. CONSTITUTION:A retainer support shaft 7' is secured to a Z-shaped retainer member 15 and rotatably supports a drive pulley 2 from the upper side in such a manner that the pulley 2 is suspended. The other end of the retainer member 15 is secured to a base 8. The retainer member 15 is formed such as to have a proper deflecting property (bending compliance) which is experimentally set by controlling its rigidity. Accordingly, when printing is effected while actuating the printing type moving apparatus of such a structure, the shaft 7' is tilted counterclockwise by virtue of the deflection of the retainer member 15 caused by the braking force applied when printing and consequently generates a crown correcting force by which the printing type belt is shifted downwardly, thereby cancelling the tendency to raise the printing type belt as the result of the braking force applied by the printing operation.

Title: Semiconductor junction detection method
Inventor: MIKAMI AKIRA
IPC: H01L21/66
Filed: 1990-05-08
Abstract: PURPOSE:To improve accuracy and to shorten measurement time by irradiating the surface of the 1st conductive semiconductor with a charged particle beam, creating a reverse bias situation between the 1st and 2nd semiconductors, etching the surface, and detecting that the charged beam has reached a junction by measuring the current flowing through the electrode. CONSTITUTION:The sample has a high resistance because of the junction and the junction makes it difficult for a charged particle beam 6 to create a current. As a result, the electric charge 10 from the charged particle beam 6 accumulates in the surface of an n-type semiconductor 1 and the surface is charged up. This situation is similar to crating a reverse bias situation in the pn junction. Also, the irradiation of the sample with Ar<+> ions of the charged particle beam 6 causes a surface 4 to be etched and cut in the direction of a junction 3. As this proceeds, the inside of the material is gradually exposed. However, when the irradiation with the charged particle beam 6 reaches the junction 3, the charged up situation disappears and the electric current caused by the charged particle beam 6 essentially becomes the current of the resistant components of a p-type semiconductor 2 and increases dramatically compared to the value electric current flowing till the charged beam 6 reaches the junction 3.
