Title: Continuous paper printer
Inventor: NAGASU TAKASHI
IPC: B65H23/188
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To realize a regularly stable sheet traveling even if the sheet width is changed by providing such a structure that the neutral position of a buffer plate provided in such a manner as to be capable of protruding and recessing to a sheet carrying path between a tractor and a pair of fixing rollers can be determined according to the width of the sheet to be printed. SOLUTION: When a sheet 5 to be fed by a tractor 6, after an electrostatic latent image formed on the surface of a photosensitive drum 1 is developed by a processor according to print signal, travels in front of a transfer device 4, the sheet 5 is pressed onto the surface of the photosensitive drum 1 by a retractor 7 to transfer the toner image to the sheet 5. Thereafter, the sheet 5 is fed to a pair of fixing rollers 10 and 11 after solving the difference in paper feeding speed by a buffer plate 8 changed in position by a spring 14 to fix the toner image. In this case, the width of the sheet 5 is detected by a sensor 15, and the neutral position of the buffer plate 8 is determined on the basis of the resulting sheet width. According to this, a regularly stable sheet traveling can be ensured regardless of the sheet width.

Title: Liquid level detector
Inventor: FUKUDA NORISUKE
IPC: G01F23/28
Filed: 1979-04-06
Abstract: PURPOSE:To provide a highly sensitive liquid level detector which permits obtaining a signal representative of a liquid level at a high output level, by subjecting an optical fiber consisting of a core and a clad to heat distortion so as to make uneven an interface between the core and clad, and detecting variations, which are caused by a liquid, in a scattering loss occurring in the uneven portion of the optical fiber. CONSTITUTION:An optical fiber 6 consisting of a core and a clad is bent, and that portion of the core and clad which is in the bent section of the optical fiber 6 is thermally distorted. Thus, an interface between the core and clad is made uneven. As a result, a loss of light propagated through the optical fiber 6 can be reduced to a great extent, and a scattering loss and radiation loss of light occur in the bent section of the optical fiber 6. Consequently, a largely varying signal can be extracted. Thus, a simply constructed, highly sensitive liquid level detector can be obtained.
