Title: Process controller
Inventor: UENO TAKASHI
IPC: G05B7/02
Filed: 1991-01-18
Abstract: PURPOSE:To automatize the accurate control of small deviation by performing the feedback control of a process while automatically stepwise changing a gap. CONSTITUTION:When a gap GP is set at the time of PID control, a gap changing part 2 reduces a gap set value GP stepwise by  GP at intervals of a certain time. A PID control part 1 compares the deviation between a target value SV and a process measured value PV taken into a measuring instrument Se with the gap GP given from the gap changing part 2 by a deviation comparing part 11. When this deviation is smaller than the gap GP, operation is not performed; but when it is larger than the gap GP, PID operation based on the deviation is performed by a PIV control part 12 to obtain a next manipulated variable MV. This variable MV is given to an operation end Pe to control the process.

Title: Output module
Inventor: YAMAGUCHI YUZURU
IPC: G05F1/45
Filed: 1990-01-12
Abstract: PURPOSE:To ensure the connection of an output module regardless of an AC or a DC that drives a load by turning on and off a control element with the control output and then turning on and off a drive element which can conducts in both directions with the output of the control element. CONSTITUTION:When an output signal ON is set at a low level, a photodiode 12a of a photocoupler 12 emits the light with the current supplied from a power supply. Thus a phototransistor 12b of the photocoupler 12 is turned on and conducts with the light emitted from the photodiode 12a. Then the voltage of a level equal to the value obtained by dividing the DC power voltage by a ratio set between the resistances R2 and R3 is applied to the gate of a transistor TR. This applied voltage can turn on the TR and the TR is turned on and conducts, and the DC output of a rectifier circuit 14 flows between the source and the drain of the TR. When the signal ON is set at a high level, the photodiode 12a emits no light and no power is supplied to an AC load 15. Thus both AC and DC loads can be turned on and off.

IPC: B65B25/04
Filed: 1992-01-16
Abstract: PURPOSE:To cut a packaging sheet assuredly and beautifully, and also pinch the end of the cut packaging sheet assuredly by holding the approximate total lateral width of the packaging sheet by a pressing member and cradles. CONSTITUTION:When a packaging sheet 1 is pulled out by a pull-out mechanism 58, the roll side of the packaging sheet 1 is cut. First, a pressing member 60 holds the packaging sheet 1 by pressing the packaging sheet 1 to cradles 67, 68. Then, a cutter 59 cuts the packaging sheet 1 at a stroke. In this case, since the pressing member 60 extends the approximate total lateral width of the packaging sheet, the approximate total lateral width of the packaging sheet 1 is held by the pressing member 60 and the cradles 67, 68. Therefore, when the cutter passes by, the packaging sheet is not pulled out and cut assuredly and beautifully without wrinkles. Then, if the end of the beautifully cut packaging sheet is let out from the cradles, the pull-out mechanism can assuredly pinch the end of the packaging sheet.
