An imaging apparatus includes an imaging element, an image signal transmitter, an image signal receiver, a signal processor and a control unit. The imaging element includes pixels arranged in two-dimensional array. The pixels output an imaging signal in synchronization with a first synchronizing signal. The image signal transmitter superimposes a second synchronizing signal on the imaging signal and transmits an image signal. The second synchronizing signal indicates a start position in vertical and horizontal directions in the two-dimensional array and is different from the first synchronizing signal. The image signal receiver receives the image signal from the image signal transmitter, and separates the received image signal into the imaging signal and second synchronizing signal. The signal processor processes the separated imaging signal based on the separated second synchronizing signal. The control unit receives the first synchronizing signal, and controls peripheral circuits in synchronization with the first synchronizing signal.

A data transmission system or an electronic camera in which data is transmitted from a first block to a second block is disclosed. A requesting means notifies from the second block, a request of receiving data from the first block at least in predetermined units thereto. A reserving means notifies, from the first block, the readiness of outputting data to the second block, in predetermined units thereto. A data outputting means outputs, from the first block, data to the second block on the basis of the notifications from the requesting means and the reserving means. Thus, it is possible to efficient and effective data transmission between two data processing blocks.

摘要:
A method of performing anisotropic etching more than once with respect to a semiconductor substrate (1) is provided with the steps of performing first-time anisotropic etching by using a first etching mask (2) so as to form a first anisotropically etched region (4) which is hollow, forming a second etching mask (7) over the first etching mask (2), performing second-time anisotropic etching by using the second etching mask (7), and previously forming the first etching mask (2) from a material which is resistant to an etchant used for patterning the second etching mask (7) before the first-time anisotropic etching is performed. Thus, the edge portion (6) of the first etched region (4) is protected so that its configuration is excellently maintained. By way of example, either of the etching masks is composed of a dielectric material such as a silicon dioxide film, while the other etching mask is composed of a metallic material such as Au and Ti, and the second-time anisotropic etching is performed by using diluted potassium hydroxide.
摘要:
The invention relates to a foam glass having a foam layer and a crust layer which covers at least one major surface of the foam layer. The crust layer is formed so as to have a thickness of from 1.5 to 20 mm and an apparent specific gravity of from 0.8 to 1.7, whereas the foam layer has an apparent specific gravity of from 0.3 to 0.6. The powder materials of the foam layer and the crust layer are respectively granulated prior to firing operation. This foam glass has good impact resistance, flexural strength and machinability including cuttability. By dispersing 15-30 vol % of glass grains 0.5-5.2 mm in diameter in the crust layer the foam glass is improved in surface hardness and flaw resistance. When the foam glass is reinforced by embedding therein a metal material such as wire netting, the metal material is pretreated with either a mixture of a silica based glass powder and an adhesive liquid binder or a dispersion of a silicon alkoxide optionally together with another metal alkoxide in a liquid medium to ensure firm adhesion of the metal material to the glass matrix and enhance mechanical strength and fire resistance of the foam glass.
