Title: Tape take-up device
IPC: B65H18/26
Filed: 1992-03-25
Abstract: PURPOSE:To provide a tape take-up device capable of taking up a tape in a good shape, without damaging the taken-up tape and easily carrying out assembly maintenance. CONSTITUTION:It is furnished with a touch roller 6 having a circular arc outer peripheral surface the central part of which in the cross direction is made high and having a crown rotating while pressing a tape 10 taken up by a take-up shaft 1. Additionally, it is furnished with a columnar touch roller 8 having a flat outer peripheral surface in the cross direction and rotating while pressing the tape 10 taken up by the take-up shaft 1.

Title: Analog/digital converter
Inventor: HARADA TAKASHI
IPC: H03K5/08
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an analog/digital converter which can prevent the occurrence of ringing and kickback due to the change of the input impedance of an analog input terminal by making the input impedance of the analog input terminal to be constant in terms of AC and DC and controlling the change quantity. SOLUTION: An adjusting switch 118 is turned on when an analog connection switch in a comparator is turned off and is turned off when the switch is turned on. When the analog connection switch is turned off, an analog input terminal 5 is separated from a capacitor in the comparator but an adjusting capacitor 117 is connected through the adjusting switch 118. Thus, the input impedance of the analog input terminal 5 is considered to be constant regardless of the state of the analog connection switch. Then, the change quantity of the input impedance of the analog input terminal 5 can be controlled and the occurrence of ringing and kickback due to the change of the input impedance of the analog input terminal 5 can be prevented.

Abstract: PURPOSE:To detect the amt. of a lap joint part of a belt-like member by calculating the lap joint parts of the beginning end and the ending end of winding of the belt-like member based on the rotational angle and diameter of a molding drum. CONSTITUTION:When the beginning end Aa of winding of a belt-like member A reaches the first end detector 5, an angle detector 10 begins to work and a rotational angle of a molding drum 1 after the beginning end Aa of winding is detected by the first end detector 5 until it is detected by the second end detector 6 is measured.

Title: Stamped character reader
Inventor: OSHIMA YOSHITAKA
IPC: G06K9/00
Filed: 1989-03-20
Abstract: PURPOSE:To correctly read a stamped character even when a stuck ink quantity is sufficient or not by deciding a stamped character part when a recessed part or ink is detected. CONSTITUTION:A light scanning means 3 operates a read object 2 and/or a light irradiating means 1, relatively scans the read object 2 by the illumination light, a height detecting means 4 receives the reflected light of the illumination light, detects the height of a light illumination part, a light detecting means 5 receives the reflected light of the illumination light. Thus detects its intensity. A stamped character part deciding means 6 decides whether or not the illumination point is the stamped character par based on the outputs of the height detecting means 4 and the light detecting means 5. Consequently, even when the ink is blurred, if the recessed part can be detected, the character can be read, and even when the recessed part cannot be detected, if the ink is sufficiently stuck, the character can be read. Thus even when the stuck ink quantity is sufficient or not, the stamped character can be correctly read.
