Abstract: PURPOSE:To perform compensation without using any temperature sensor and to facilitate adjusting operation by providing three resistors among three terminals to which voltages signals of different temperature characteristics including zero are applied. CONSTITUTION:In a constant current circuit 200, a bridge circuit 100 which is supplied with a constant current transduces pressure into an electric signal by utilizing piezoelec tric effect and a correcting circuit 300 generates a temperature correction signal for temperature compensation. An adding circuit 400 adds the pressure signal of the circuit 100 to the temperature correction signal of the circuit 300 to compensate the tempera ture characteristic of the pressure signal from the circuit 100 and an amplifying circuit 500 amplifies and output the signal. At this time, one-terminal sides of the resistors R9 - R11 in the circuit 300 are connected to a terminal (d) where the voltage having the largest temperature characteristic is applied, the ground of 0 potential with the least temperature characteristics, and the resistance terminal of the circuit 400 where a voltage with an intermediate temperature characteristic is applied. For the purpose, the resistor R9 or R10 is trimmed to enable and facilitate the adjusting operation for the temperature characteristic of a temperature characteristic compensating current flowing to the resistance 11.

Abstract: PURPOSE:To eliminate the effect of sliding resistance at the time of relative reciprocating movement of a scale on a slider supporting member, by freely moving an index scale and a wire spring, which energizes a slider that is relatively reciprocated with respect to a detecting mechanism. CONSTITUTION:An index scale 10, a slider 13 which is relatively reciprocated and reads the amount of displacent, and a detecting mechanism 3 are connected by a highly rigid member 20, which is a supporting member, and a wire spring 21, which is an energizing means for compressing the slider 13 to the scale 10, and the like. Said spring 21 is made to be freely moved in the direction in parallel with the moving direction of the slider 13 through a guide part 24.

Title: Paper sheets delivery device
Inventor: MURAI TAKESHI
IPC: B65H3/54
Filed: 1985-06-19
Abstract: PURPOSE:To aim at stabilization in the separatory delivery motion of paper sheets, by installing a deformation regulating device which is situated in a central part at the delivery side of stacked paper sheets, giving some pressing force to it in contact with the forefront paper sheets, and makes the curling deformation of each of paper sheets so as to be prevented. CONSTITUTION:A guide roller 39 advances on the top of a paper sheet B synchronously with a pickup roller 34, while the paper sheet is checked for its curling deformation at the counter delivery side by the guide roller 39,so that an attitude of each paper sheet is kept constant, thus the paper sheet is stably deliverable toward a separatory part.In addition, since the guide roller 39 gives some pressing force with its own weight, it prevents a Z-shaped lapping fold in a central part of the paper sheet from occurring, checking vibrations in front and in the rear of a paper sheet group, thus the paper sheet is stably deliverable toward the separatory part. In consequence, misfeed or oblique motion of the paper sheet is prevented from occurring and what is more, stabilization in the separatory delivery motion of these paper sheets is securable.
