Abstract: PURPOSE:To realize a three-wire light-adjustment lighting device with simple circuit configuration by providing a light-adjustment control circuit for receiving signals that an a.c. power supply is phase-controlled for a light adjustment level and controlling the output of an inverter circuit. CONSTITUTION:A light-adjustment control circuit 33 is provided for receiving signals that an a.c. power supply AC is phase-controlled for a light adjustment level 37 and controlling the output of an inverter circuit. A waveform shaping circuit 31 converts the a.c. signals phase-controlled for a light adjustment level into PWM(pulse width modulation) signals, e.g. with the pulse width corresponding to their continuity angles or d.c. signals with the potential level varied with a light adjustment level, which are input into the light-adjustment control circuit 33. The light-adjustment control circuit 33 varies the drive frequency of an inverter circuit in accordance with such signals and performs light adjustment of a discharge lamp 25. It is thus possible to realize a three-wire light- adjustment lighting device and intend easy wiring and low cost of the device.

Title: Plating device
Inventor: NAKA MASATOSHI
IPC: C25D21/12
Filed: 1990-09-20
Abstract: PURPOSE:To easily and adequately set a plating current by actually measuring the 1st current density of a standard plate in the same plating cell, comparing the same with a set 2nd current density and attaining the coincidence of the two current densities. CONSTITUTION:The current flowing in the standard plate 4 is detected via a shunt 11 simultaneously with the start of plating on an object 5 to be treated. This current is fed back as the current density via an A/D converter 13 to a CPU 8. The CPU 8 compares and computes the current density which is the fed back and actually measured value and the 2nd current density which is a set value. The CPU controls the output voltage of a DC power source until the two current densities coincide with each other. The plating current is held for a prescribed period of time after the two current densities coincide and thereafter, the output of the DC power source 6 is stopped by the signal from a sequencer 7.

Abstract: PURPOSE:To perform ignition without rail and maintain a stable flame in a pulverized coal combustion furnace by a method wherein a hollow cone of pyramid shape is provided on the furnace side of a pulverized coal burner nozzle, and its side is connected to the venturi part of the pulverized coal burner nozzle by a pipe. CONSTITUTION:When air-fuel mixture is supplied from a pulverized coal transfer pipe 7 into a pulverized coal burner nozzle 8, a negative pressure is produced in the venturi joint parts of pipes 12 as the air-fuel mixture passes through a venturi 13. Thereby, a current shown by arrows 33 is produced in the pipes 12, which causes the air-fuel mixture retained at the rear side 11 of a pyramid shape hollow one 10 to be sucked into the pipes 12. This air-fuel mixture is joined to the air-fuel mixture current 30 after heated by a heater 14 up to nearly the ignition temperature. Consequently, the air-fuel mixture is heated up, so that the ignition takes place certainly and a stable flame can be maintained.

Filed: 1985-11-12
Abstract: PURPOSE:To obtain optimum gradation by executing the gradation conversion of image signals of red, green and blue in accordance with specific equations at the conversion of digital data obtained after the end of image processing into analog data. CONSTITUTION:When it is defined that the density of an image signal to be outputted at present is D, a gradation value after image processing is (n), the maximum value of the density signal D is Dmax, its minimum value is Dmin, and the maximum value of the gradation value is N, the density signal D is expressed by the equation D=(Dmax-Dmin)(n/N)<p>+Dmin-(1) (in the equation, P is the factor of conversion). The conversion characteristics shown in the drawings are obtained by simplifying the equation like D=Dmax(n/255). In this case, the number of gradations (gradation capacity) N is 256 stages (8 bits) and the density is assigned to all density areas in the gradation capacity of 256 stages. The characteristic curve shown in the drawings indicates the conversion factor p=3 and the change of density gradation is increased in the low density area, so that the gradation is appropriate to human's psychological evaluation. Thereby, an output image of high quality can be obtained by executing gradation conversion on the basis of the characteristics shown in the drawings.
