Abstract: PURPOSE:To prevent excessive pressure rising at the time of the occurrence of water hammer by branching a water feed pipe connected to a pump delivery pipe through a check valve, and connecting the above water feed pipe to the water side of a pressure tank through a check valve. CONSTITUTION:One side of a branched delivery pipe 3 is connected to an air supplementary reservior 4, and its other side is done to a water feed pipe through a check valve 5.

Abstract: PURPOSE:To reduce loss during saturation and to prevent an element from breaking down owing to abnormal heating by connecting a resistance with a desired value to the collector of a TR bipolar TR connected to an MOSTR field effect TR on Darlington basis. CONSTITUTION:The resistance Rc (with a resistance value Rc) is added between the collector electrode Co of the transistor (TR) Q2 and the drain electrode D of the MOSTRQ1. Thus, the resistance Rc having the value close to Ron/hfe where Ron is the ON resistance of the MOSTRQ1 and hfe is the current amplification factor of the TRQ2 is inserted as shown in a figure to supply a base current IB proportional to a collector current IC, and the TRQ2 is saturated sufficiently to obtain a small saturation voltage VCE(sat). The loss during saturation is VCE(sat).Ic, so it is preferable that the saturation voltage VCE(sat) is extremely small.

Abstract: PURPOSE:To form a large-contrast latent image whose character part and skin part are mutually polarized in a reverse direction on a dielectric belt provided with a ferroelectric layer. CONSTITUTION:By impressing a voltage(-Es) for saturating the polarization of the ferroelectric layer 1c on a negative polarity side on the belt 1 whose temperature is near normal temperature at first, the polarization processing of the layer 1c is executed.

Abstract: PURPOSE:To stop the operation of a robot immediately after a driving current value exceeds a prescribed limit value when a driving-current check instruction is read out, by storing the limit value in a robot control part together with instruction data. CONSTITUTION:Distributed pulses Zp generated by a robot control part RBC through a pulse distributor PDC and feedback pulses FBP are applied to an error register ERR to process their difference by DA conversion, and a difference voltage Ec from an actual-speed conversion voltage Es is calculated to turn a motor DMZ by the error voltage, so that a robot moves at a commanded speed. Once a driving-current check instruction is read out, a current instruction signal CTS is outputted to fetch an AD-converted driving-current value ID through a multiplexer MPX, and prescribed processing is performed to find a limit value Im, which is stored in a memory TCM. The limit value Im from the memory TCM and the drivibg current ID from the multiplexer MPX are compared mutually by a comparison part CMR and when the current exceeds the limit value, the operation is stopped, thus improving safety.

Title: Method for binarizing picture
Inventor: ITO MINORU
IPC: G03F1/84
Filed: 1990-07-13
Abstract: PURPOSE:To calculate an exact binarized threshold value by avoiding dependency to a pattern area distribution proportion not with the density histogram of the picture whole face but with the difference of the histogram of a local area. CONSTITUTION:An SAL and an SAH are the areas of an area AL and an area AH respectively, a window is scanned within a picture, when average density or a sum within the window is high, the SAH is larger than the SAL and when it is low, the SAL is relatively larger than the SAH. Then, when the value of the SAL when the SAL is larger is defined as an SALP and the value of the SAL when the SAH is larger is defined as an SALq, a difference of a density histogram DELTAf becomes '0' when SALq=SALq, since SALpnot equal to SALq can be conditioned easily by window scanning, the value of (x) to be DELTAf=0 becomes x=(dL+dH)/2 and an exact threshold value can be selected. Thus, an exact binarized threshold value can be calculated.
