Title: Removal of co in reformed gas
Inventor: SOMA TAKAO
IPC: H01M8/06
Filed: 1994-06-08
Abstract: PURPOSE:To obtain the highly pure H2 by treating a reformed gas with a H2- purifying device to lower the concentration ratio of other gases to H2 into a smaller ratio than that of the reformed gas, and subsequently reacting CO in the gas treated with the H2-purifying device to convert the CO into gases other then CO. CONSTITUTION:A reformed gas produced from a methanol-water mixture solution, etc., as a raw material with a reformer is treated with a H2-purifying device composed of H2-separating members produced by forming H2-separating membranes comprising a Pd-Ag alloy, etc., on the outer surface of a porous base pipe such as a porous Al2O3 pipe at >=20 deg.C to lower the concentration ratio of other gases to H2 gas for enhancing the concentration of the H2. The treated reformed gas is allowed to pass through a CO converter using a methanation catalyst such as Al2O3 carried on Ni at approximately 100-500 deg.C to hydrogenate the CO contained in the reformed gas. Thus, the CO concentration is lowered to approximately 0.1ppm or below. The purified hydrogen gas is supplied to a fuel battery.

Abstract: PURPOSE:To improve PLL loop(phase locked loop) characteristic in a color signal processing and to widen the band of a reproduced color signal by adding output signals of 1st and 2nd multipliers respectively and obtaining a 3rd reproduced color signal to be the final output signal. CONSTITUTION:A low frequency color signal (a) coming from an input terminal 1 is subjected to frequency conversion into a 1st reproduced color signal (e) in a frequency fC at the 1st multiplier 2 by using a carrier signal (h) in a frequency fC+fS. Moreover the output signal (d) of a switch circuit 5 is subjected to frequency conversion into a 2nd reproduced color signal (g) in the frequency fC at a 2nd multiplier 6 by using a signal (i) being the result of +90 deg. phase shift of the carrier signal (h) at a phase shifter 7. When the 1st reproduced color signal (e) and the 2nd reproduced color signal (g) are added by an adder 8, the 3rd reproduced color signal (k) being an output signal of the adder 8 is a signal without crosstalk component in the frequency fC and the major component in the frequency fC+2fS. Thus, the frequency characteristic of the reproduced color signal is improved and the characteristic of the PLL loop in the color signal processing is improved.

Abstract: PURPOSE:To prevent the deterioration of differential gain/differential phase DG/ DP characteristics by fixing an input video signal to a prescribed value by a clamping circuit, amplifying its output, and thereafter, cutting a signal component exceeding a prescribed level by a clipping circuit. CONSTITUTION:An input video signal VIN is inputted to a clamping circuit 1, and a sink chip level of the signal VIN is fixed to a prescribed DC voltage VDC.

Title: Recording power stabilizing device
Inventor: ARAKI MITSUHIRO
IPC: G11B7/125
Filed: 1990-05-16
Abstract: PURPOSE:To stabilize recording power by detecting an amplitude from the pulse modulated beam output of a semiconductor laser as a recording light source by a photodetector and controlling the driving current of the semiconductor laser in the case of recording information corresponding to error compared with a rated value. CONSTITUTION:A modulation circuit 15 modulates the pulse of the driving current of a semiconductor laser 1 according to a recorded signal, and the pulse modulated beam output is detected by a PIN diode 2, converted by a current/voltage conversion circuit 3 and afterwards amplified by a wide-band video amplifier 4. A differential amplifier 9 calculates difference between positive and negative envelope waveforms obtained from the alternating current component of this signal by positive and negative envelope detection circuits 7 and 8 so as to obtain a signal corresponding to the amplitude of the pulse modulated beam output. As difference between this signal and a recording reference voltage V3, a recording power error signal is obtained by a differential amplifier 10 and corresponding to this signal, a current driving circuit 14 controls the value of the driving current. Thus, against the optical output fluctuation caused by a temperature change or the like, the recording power can be kept at the rated value and stabilized.

Title: Touch screen controlling system
Inventor: HASHIMOTO SHIGEO
IPC: G06F3/0487
Filed: 1984-06-22
Abstract: PURPOSE:To obtain a touch screen controlling system having high reliability by providing such a spatial redundancy as plural parts one-push operation to an input operation, with respect to a touch screen whose simple substance reliability is low. CONSTITUTION:In case an operator has decided that an RCIC94 should be started as a result of an inspection of a plant state of an atomic reactor, he pushes each ''RCIC start part'' of a touch screen 1 and a touch screen 2 by using both his hands. These signals are inputted to a CPU6 through touch screen input control devices 1, 2 (4, 5), processed by an input processing part, and thereafter, sent to a comparing and collating part. The comparing and collating part decides them to be a normal input since both of the two inputs request simultaneously ''RCIC start'', and outputs a start command to an RCIC control device 93. CRTs 1, 2 (31, 32) change a color of ''RCIC start'' displayed in green so far, to yellow, and indicate that the processing has been received. When the RCIC94 is started actually, the ''RCIC start'' is changed to red from yellow.

Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To suppress noise affected on a specific area of a field scanned by the unit of lines by replacing a pixel having noise with an average pixel value of a nearby pixel belonging to a prescribed processing window. SOLUTION: A difference calculation circuit calculates a difference Di (D1-D7) between luminance values Xi (X1-X7) of a pixel adjacent to a processing pixel value X of a processing window. Then a Dmax &Dmin detection block identifies a maximum value and a minimum value of a received difference Di. Upon the receipt of the Dmax and Dmin by an adaptive threshold level detection processing block adopting a 1st fuzzy logic, they are referenced as a membership 1 and corresponding values to the threshold levels Th1, Th2 are generated. Then a local adaptive noise smoothing processing block adopting a 2nd fuzzy block generates a set of output values Ki based on the threshold level parameters Th1, Th2 referenced by a membership 2 and generated before. A final filter block generates a pixel Xout as a sum of weighting factors.
