Title: Thickness measuring method and device therefor
Inventor: HYODO SHIGETOSHI
IPC: G01B17/02
Filed: 1994-11-30
Abstract: PURPOSE: To measure the remaining wall thickness of a defective part inside a steel pipe online accurately and quickly. CONSTITUTION: Ultrasonic wave is projected at an angle by the angle beam method to the external surface of a steel pipe 1 from a non-contact transmission probe 2. A wave (S) reflected on an external surface is detected by a non- contact reception probe 3a, and waves (T, B) reflected inside the pipe 1 are detected by a non-contact reception prove 3b. The time from the detection of the wave (S) reflected on the external surface to the detection of the waves (T, S) reflected inside is converted into thickness and output. Although using non-contact probe, this eliminates the effects of distance variations from the probe through materials, and makes measurement of high speed and accuracy possible to be performed.

Title: Sheet feed device and electrophotography press
Inventor: FUIRITSUPU EI BIRINGUSU
IPC: G03G15/00
Filed: 1994-12-27
Abstract: PURPOSE: To separate a plurality sheets of feed rapidly and effectively from each other by allowing a torque limiting bias device to rotate a retard roll in a specified direction when one sheet passes through a nip and rotate it in reverse direction when a plurality of sheets pass through it so as to move the sheets in reverse direction. CONSTITUTION: When a retard roll assembly 82 is rotated by a friction with a feed roll, a spring 90 is wound up by a friction between the spring 90 and the inner peripheral part 85 of a cylindrical part 84 so as to provide a specified torque. When sheets are fed one by one through a retard nip continuously, a torque given to a retard roll becomes superior to an internal frictional force enough to overrun a spring force in feed direction. When the sheet is fed doubly to the nip, a torque transmitted to the retard roll becomes smaller than that stored in the spring, and the spring 90 rotates a retard surface 86 reversely to the feed direction so as to return the doubly fed sheet in the tray direction.
