摘要:
A probe configured to receive an acoustic wave from an object including an element (1) having a cell structure (2), in which a vibration membrane (7) having one of a pair of electrodes formed with a gap arranged therebetween is supported so that the vibration membrane can be vibrated by the acoustic wave; a light reflection layer (6) provided at a position near the object with respect to the element and configured to reflect light; and a support layer (10) provided between the element and the light reflection layer and configured to support the light reflection layer.
摘要:
A capacitance type transducer (100) includes one or more cells having a structure in which a vibrating film (101) including one electrode (102) of a pair of electrodes (102, 103) formed spaced apart from each other is supported to be capable of vibrating. The cells are disposed on one surface of a substrate (201). An acoustic matching layer (205) is provided between a water-resistant sheet (202) and the cells. A water-resistant frame (203) is disposed to surround a side surface of the substrate (201). The sheet (202) is bonded to an end face of the frame (203) to cover an opening of the frame (203).
摘要:
A liquid crystal device is constituted by a pair of oppositely disposed substrates having opposing inner surfaces and opposing electrodes thereon, and a chiral smectic liquid crystal disposed between the opposing electrodes. The liquid crystal device has an effective optical modulation region (2) and a peripheral region (3) outside the effective optical modulation region. In the device, liquid crystal molecules in the peripheral region have a pretilt angle (α₂) which is larger than a pretilt angle (α₁) of liquid crystal molecules in the effective optical modulation region. As a result, a local pressure irregularity or a cell thickness change caused by a liquid crystal molecular movement along an extension of the device is effectively suppressed.
摘要:
There is provided an image display apparatus and an image erasing method, by which a color image made of an ink can be displayed by fixing the ink on the recording medium, and, when it is desired to erase the color image, the color image on the recording medium can be erased by image erasing means. Therefore, the present invention comprises ink application means 1 for applying an ink onto recording medium 10 in accordance with image data, and image erasing means 4 for erasing the image formed on recording medium 10 by ink application means 1, wherein, when the solubility parameter (SP value) of the substance remaining on recording medium 10 after applying the ink is taken as SP p , the SP value of the substance constituting the surface of the recording medium is taken as SP m , and the SP value of the substance constituting the surface of the image erasing means is taken as SP c , said SP p , SP m and SP c satisfy the relationship |SPp - SPm| > |SPp - SPc|.
