Abstract: PURPOSE:To provide a two-bed water activating device with the water flow velocity region to obtain appropriate fluidization of ceramic grains enlarged, capable of enhancing the water activating effect in the region, with the water pressure drop reduced and capable of keeping the grain surface always clean. CONSTITUTION:A spiral water current is supplied from the side 14a of the lower bed 14 of a two-bed water activating device 11.

IPC: G02F1/03
Filed: 1987-08-07
Abstract: PURPOSE:To increase the response speed of an optical shutter by impressing the electric field higher than the electric field which maximizes the intensity of the transmitted light from the optical shutter, as an initial electric field, to the optical shutter. CONSTITUTION:The light from a halogen lamp 11 is guided through a heat ray absorbing filter 12 to a light guide 13 from which the light is projected to a rod lens 14. The light projected by this lens 14 is condensed to the point of an optical shutter array 10 and the electric field of a prescribed pulse width is impressed on the optical shutter element at the adequate point in this array 10 so that the light is transmitted therethrough. The electric field higher than the electric field to maximizes the intensity of the transmitted light from the optical shutter in the electrostatic characteristic is impressed as the initial electric field on the optical shutter in the beginning of driving. The increase of the intensity of the transmitted light in the optical shutter is thereby extremely accelerated when the optical shutter is driven. The desired intensity of the transmitted light is thus obtd. in an extremely short period of time and the response speed of the optical shutter is increased.

Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To speedily reset required image-forming-operation-conditions, in all the cases an auto-clearing function operates. SOLUTION: After an image forming operation or any key operation, the auto-clearing function is initialized (steps 222 and 224). Thereafter, in the case no operations are carried out until auto-clearing time elapses, the contents of image-forming-operation conditions at the point in time are stored in a RAM (step 214), and the image-forming-operation conditions are altered to standard conditions determined in advance (step 216). When an instruction is then given to cancel the auto-clearing, the set contents of the image-forming-operation conditions before the execution of the auto-clearing function are read from the RAM, and set again as new image-forming-operation-conditions. Thus, the image-forming-operation conditions can speedily be set back to the conditions used before the execution of the auto-clearing function.

Title: Picture quality evaluating method for image

IPC: G06T1/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To evaluate image quality with good correlation with human sensations and to enables quantitative total picture quality evaluation by evaluating the image quality by using a total evaluation value obtained from definition, granularity, and gradation properties of the image to be evaluated. SOLUTION: To obtain the total image evaluation value, a ladder pattern of different spatial frequency is read by, for example, an image reader 111 and the value obtained by correcting its frequency characteristics is regarded as definition 112. For example, image information to be evaluated is read by an image reader 121 to find a spatial frequency component of the image to be evaluated and the value obtained by multiplication by human visual frequency characteristics, integration in a frequency area, and correction with the mean lightness, etc., of the image is decided as granularity 122. Further, the value calculated on the basis of a measurement of a lightness difference, etc., sensed for an image outputted at an adjacent gradation level is regarded as gradation characteristics 132.  Then the total picture quality evaluation value is found from a linear equation including those definition, granularity, and gradation characteristics as variables.
