摘要： A method for forming through holes, which has laser beam as the light source to project the laser beam to the work object using an optical system through a photomask for the formation of through holes on the work object by ablation processing, comprises the steps of increasing the concentration of the optical processing energy contributing to the process using the reflected beam created from the work object in the laser ablation processing; and forming each of through holes having the configuration enabling the narrower end to be changed to the wider end in the incident direction of laser beam. With the structure thus arranged, it becomes possible to increase the energy concentration that contributes to the process as compared with the usual ablation processing, because the reflected beam created in the ablation processing can be utilized again for the optical processing. Then, each of the through holes can be formed easily in the configuration in which the narrower end changes to the wider end in the incident direction of laser beam, which cannot be easily processed by the application of the usual ablation processing.

摘要： An image can be outputted with a high sharpness without deteriorating a resolution. In order to output an image of a high picture quality while suppressing the occurrence of a moire, an exposure amount is modulated in accordance with pixel density information of the image divided into pixels of a predetermined size by an exposure amount modulating unit in a light scanning unit, thereby expressing an image dark/light state. In this case, in a highlight density region in which a pixel density is equal to or less than ⅓ of the maximum image density, the density data of two adjoining pixels is modulated by one pixel and the other pixel is not recorded. In a density region in which the image density lies within a range from ⅓ to ½ of the maximum image density, a part of the density data of one of the two adjoining pixels is transposed to the other pixel. In a density region in which the image density is equal to or larger than ½ of the maximum density, the pixel transposition is not performed.

摘要： An image forming apparatus includes a movable photosensitive member, a slit for imagewise exposure of said photosensitive member to light in a slit exposure area having a width in a direction of movement of said photosensitive member, and a movable reflecting member for forming a non-image area on said photosensitive member by light from said reflecting member. When blank exposure is effected, the reflecting member is disposed at a first position or a second position. When the reflecting member is disposed at the first position, the light from the reflecting member is substantially condensed on or adjacent to an upstream end of the exposure area width on the photosensitive member with respect to the movement direction of the photosensitive member, and an area before an image area on the photosensitive member in which an image is formed by the slit exposure means is exposed to the light. When the reflecting member is disposed at the second position, the light from the reflecting member is substantially condensed on or adjacent a downstream end of the exposure area width on the photosensitive member, with respect to the movement direction of the photosensitive member, and an area after the image area is exposed to the light.

摘要： A liquid crystal display apparatus is disclosed which can prevent occurrence of flicker regardless of display modes. The apparatus includes a liquid crystal modulation element which includes a liquid crystal layer between a first electrode and a second electrode, a controller which controls a potential difference to be applied between the first and second electrodes. The apparatus operates in first and second modes, which are different in the light amount entering the element. A memory stores first information for the first mode and second information for the second mode as controlling information on a potential difference between the electrodes for suppressing flicker within a certain range. The controller controls the potential difference between the electrodes based on the first information when the first mode is set and controls the potential difference between the electrodes based on the second information when the second mode is set.
