Title: Solenoid valve control system
Inventor: KATO YOICHI
IPC: G05B19/05
Filed: 1993-07-30
Abstract: PURPOSE:To transmit and receive drive information using a shared transmission line by designating the number of a station using communications control portions having their own numbers and provided to a programmable controller and to each solenoid valve control system, and transmitting and receiving a command packet. CONSTITUTION:Command parallel signals including information on the number of a receiving station and information on a drive command are sent to a communications control portion 20 from a programmable controller 10, and are subjected to parallel-to- serial conversion to obtain serial signals including the information on the number of the station and the information on the command. The serial signals are transmitted on a shared transmission line 30. A communications control portion 40 provided to a plurality of solenoid valve control systems 70 checks to see whether or not any serial signals exist, and starts reception immediately when detecting the serial signals on the shared transmission line 30, and retrieves only the information on the number of the station included in the serial signals. The information is compared with information on the number of a sending station, and when they are the same the information is regarded as being sent to the sending station, and then the serial signals are subjected to serial-parallel conversion and output to a solenoid valve control portion 50.

Title: Ink rail device
Inventor: NAWATE SHIGEO
IPC: B41F31/08
Filed: 1985-09-24
Abstract: PURPOSE:To make newly-supplied ink join excellently in roller-side ink and thereby to improve transfer performance, by attaching electrodes for charging ink with electricity and for repelling same to an ink rail so as to generate electrostatic actions to charge ink and to repel the same. CONSTITUTION:Ink (a) supplied under pressure by an ink pump is charged with negative electricity injected from an electrode 13 for charging ink with electricity, for instance, while it flows through an ink passage 12 in an ink rail 11. Then, it is supplied onto ink (a') on the peripheral surface of an ink transfer roll 3 and dragged upward with the rotating movement of the ink (a'), and it is repelled there by an electrode 14 for repelling ink, which has the same polarity with the ink, i.e. a negative polarity, so as to be pressed onto the ink (a') on the ink transfer roller 3. Therefore the joining of the new and old ink (a) and (a') is facilitated, the transfer of the ink (a) onto the ink transfer roller 3 is improved remarkably, and thus the outward leak of the ink (a) is prevented effectively when its comes out of a gap.

Title: Image tester
Inventor: KELLY BRUCE
IPC: G06T7/00
Filed: 1989-08-16
Abstract: PURPOSE: To enable a sheet test without an error by comparing the signal value when all the many picture elements are the luminance within a prescribed luminance range and the signal value when one of picture elements is the luminance outside the prescribed luminance range. CONSTITUTION: A logic circuit 101 outputs a binary value by depending on whether a gray scale value is within a definition area or outside the definition area by the upper level defined by a line 91 and the lower level defined by a line 91a. If the present related bit in a data word is a second binary value, the comparisons of the picture words having each area are inhibited. If a matrix bit is 0, the bit is neglected and gates are alternately provided after a comparator. A comparison system generates a signal meaning that the gray scale value of each picture element falls outside of an area to be compared and a mismatching detector outputs the signal to a determination circuit. Thus, a sheet test without an error becomes possible.

IPC: D05B69/26
Filed: 1983-11-11
Abstract: PURPOSE:To accurately stop the needle of a sewing machine at a prescribed position by adding a function to linearly simulate the attenuating property of a motor. CONSTITUTION:When an operation command S1 is applied to a main controller 1, the controller 1 outputs a clutch signal CL or a brake signal BK in response to the deviation between a speed detection signal PG and a speed command SC. When an operation command S1 goes OFF, a brake calculator 6 calculates the time T1 up to the decrease of the rotating speed of a sewing machine to the stop preparing speed N1 on the basis of the rotating speed N at that time. The controller 1 outputs the brake signal BK to stopping the needle 4b at the lower or upper limit position when the time T reaches T>=T1.
