Abstract:
An A/D converter includes a subtracter for calculating a difference between an input signal and a feed-back signal, and outputting a differential signal, a local A/D converter for converting the differential signal into a first digital signal, a local D/A converter for converting the first digital signal into an analog signal, and outputting the analog signal, as a feedback signal, to the subtracter, an integrator inserted in a feedback loop constituted by the calculator, the local A/D converter, and the local D/A converter, a correcting circuit for correcting the first digital signal output from the local A/D converter so as to obtain a second digital signal corresponding to an analog signal output from the local D/A converter when the first digital signal is input thereto, and an output circuit for outputting the second digital signal, output from the correcting circuit, as an output signal.
Abstract:
A mimeographic printing machine general comprises: a rotary plate cylinder for supporting a stencil on an outer circumferential surface thereof and having a perforation for passage of ink, the plate cylinder being rotatable with the stencil; means for supplying the ink to an inner circumferential surface of the plate cylinder; a squeegee movably received in the plate cylinder so as to come into and out of contact with the inner circumferential surface of the plate cylinder, the squeegee being operable to squeeze the ink from the supplying means toward the outer circumferential surface of the plate cylinder through the perforation of the plate cylinder; and a rod-shaped member rotatably received in the plate cylinder. The rod-shaped member is located behind the squeegee in the rotating direction of the plate cylinder and is movable with the squeegee for jointly holding the ink.

Abstract:
A stencil carrier apparatus including a semi-cylindrical driving feed roller, driven feed rollers, a pressure guide plate, and a control cam enables a used stencil from a printing drum to be reliably transported to a stencil receiver so as to be discharged out of a printing apparatus.
Abstract:
A galvannealed steel sheet having a superior spot weldability characteristic in which the steel sheet has a base steel sheet cold-rolled from a material containing 0.005 wt % or less of C, 0.005 to 0.05 wt % of Ti, 0.01 to 0.1 wt % of Al, 0.005 to 0.015 wt % of Nb and 0.0002 to 0.002 wt % of B. In the process for making, the hot-dip plating layer applied after the alloying heat treatment has an Fe content of from 9 wt % to 12 wt %.
Abstract:
The present invention provides a method for producing a thin cold rolled steel sheet, which is adapted to be formed into, for example, an external automotive plate. The method includes an appearance-finishing step by bake-coating as a final step after drawing (such as press molding), and has a remarkably high baking hardenability. The baking hardenability is a property for improving the yield strength due to the heating during the bake coating treatment and is particularly advantageous for producing a light weight automobile and for compensating the deterioration of dent resistance of the automotive plate due to the lowering of its weight, (without deteriorating the r value). The latter is an indication of the press moldability of the thin steel sheet. Furthermore, the present invention discloses an effective compounding amount of Ti which acts to fix C, S and N contained in the steel, and a continuous annealing condition properly selected depending upon the effective amount of Ti.

Abstract:
An arrangement is disclosed for reducing the overall effective size of the goods storage and discharging system in an automatic vending machine. The solenoid and transmission mechanism of each goods discharging mechanism are so disposed that the discharging mechanisms of adjacent goods storage shelves may be arranged in a back-to-back relation with the solenoids and transmission mechanisms thereof laterally adjacent each other. The overall size of the vending machine may thus be substantially reduced.
Abstract:
A device for opening a back door of an automotive vehicle which can be operated by an operator's foot. A foot pedal is located at a rear and lower portion of the automotive vehicle in an accessible position. The foot pedal is connected by actuating means to lifting means for lifting the back door in such a manner that the back door can rotate around the upper edge thereof to be opened. A door-lock release device is actuated in response to operation of the lifting means to release the lock of a locking device. The actuating means includes means for disconnecting the linkage between the lifting means and the foot pedal so that operation of the foot pedal cannot be transmitted to the actuating means.
