摘要： Methods and apparatus are disclosed for microlithographically exposing a photosensitive substrate comprising single-exposure areas and multiple-exposure areas. After exposing the substrate, line widths in the single-exposure areas are substantially the same as line widths in the multiple-exposure areas. Also disclosed are masks comprising a first mask pattern used to expose the single-exposure areas once and a plurality of other mask patterns for exposing the multiple-exposure areas a predetermined number of times. Each of the other mask patterns allows a lower intensity of illumination light flux to be distributed to the multiple-exposure areas per exposure of the substrate than allowed by the first mask pattern. Consequently, the average intensity of illumination-light flux distributed to the single-exposure area after one exposure is substantially equal to the average intensity of illumination-light flux distributed to the multiple-exposure areas after a predetermined number of exposures of such areas.

摘要： An ultrasound medical treatment apparatus includes an ultrasound applicator for applying ultrasound irradiation to a treatment target. The treatment apparatus also includes an ultrasound imaging device that transmits ultrasound pulses to image the treatment target. The treatment apparatus is capable of reducing noises occurring at an ultrasound imaging device due to the ultrasound irradiation generated by the ultrasound application during ultrasound medical treatment. The noises may be reduced by increasing a transmission power of the ultrasound pulses. Alternatively, the noises may be reduced by subtracting pre-recorded noise components from the ultrasound pulses received by the ultrasound imaging device, where the pre-recorded noise components are characteristic of noise occurring at the ultrasound imaging device due to the ultrasound irradiation generated by the ultrasound applicator.

摘要： In an improved INEPT pulse sequence, an excitation pulse, a refocus pulse and an excitation pulse are sequentially applied for .sup.1 H spins. A refocus pulse and an excitation pulse are sequentially applied for .sup.13 C spins that are spin-spin coupled with the .sup.1 H spins. A magnetic resonance signal is acquired from .sup.1 H spins or .sup.13 C spins. The second refocus pulse for .sup.1 H is applied as a slice selective pulse at a time different from the time the first refocus pulse for .sup.13 C is applied. This allows localization to be achieved without adversely affecting the flip angle of the first refocus pulse for .sup.13 C.

摘要： A projection apparatus is disclosed that can be used for projection TV and related applications. The apparatus comprises a light source, a projection optical system, a DMD with multiple micromirrors, and a controller for individually controlling the tilt of the micromirrors. The projection optical system comprises, in order from the DMD side, a first lens group, an aperture stop, and a second lens group. An illumination stop is situated between the first and second lens groups. Light from the light source passes through the illumination stop and the first lens group to impinge on the DMD. The controller coordinatedly controls the tilt of the micromirrors in the DMD so that the impinging light is selectively reflected to one or the other of the aperture stop and the illumination stop, thereby eliminating ghost-forming reflections of light not projected onto a screen.

摘要： An ultrasonic wave medical treatment apparatus capable of preventing the displacement of the focal point of the ultrasonic waves from the treatment target portion within the patient, eliminating a need for re-positioning of the ultrasonic wave applicator with respect to the patient, and taking MR images to be utilized during the treatment at a high resolution. In this apparatus, the ultrasonic wave applicator can be integrally incorporated within a treatment table for carrying the patient into the MRI gantry for taking the MR images. The surface coil for taking the MR images can be provided on a surface film of a water bag in the ultrasonic wave applicator, or on a body cavity probe on which the ultrasonic transducer is also provided. The mixing rate of the coupling fluid can be adjusted, and the impedance matching between the ultrasonic transducer and the driving circuit can be maintained by minimizing the reflected electric power from the ultrasonic transducer.
