Abstract: A content generation apparatus capable of easily confirming content data, the information of which is registered in a blockchain, is provided. An image pickup apparatus generates an image file and then immediately calculates a hash value of the image file, and transmits image file information including the hash value to a management system. In response to receipt of a registration completion notification indicating that a process of registering the image file information in a blockchain is completed, the image pickup apparatus stores registration-completed information indicating that the image file information is registered in the blockchain, relating to the image file.

Abstract: A workpiece holding method and holding system able to shorten the workpiece attachment/detachment time, wherein pressurized air is circulated through a nozzle of an ejector unit of a chuck at all times to make the inside of a suction chamber a negative pressure before chucking a workpiece, completion of chucking is detected based on a pressure value detected by a pressure sensor after chucking the workpiece, and the workpiece is unchucked by having a valve close an exhaust port to raise the pressure inside an exhaust chamber and introducing pressurized air from the ejector unit to the suction chamber.

Abstract: On receiving from a personal computer (1) a request for transmitting data for displaying a picture for inputting a user's profile in association with an MGID and an APID for specifying the personal computer (1), an EMD registration server (3) selects data recorded in correspondence to the APID based on the received APID and transmits the selected data to the personal computer (1). The EMD registration server (3) receivers the user's profile inputted based on the data from the personal computer (1) and records the user's profile in correspondence to the MGID.

Abstract: After an Si wafer is anisotropically etched through an etching mask having an opening in an anisotropically etching solution, an etching face of the Si wafer emerged by the anisotropic etching is subjected to anodic oxidation by applying a positive voltage for anodic oxidation on the Si wafer. As a result, the etching face of the Si wafer is isotropically etched due to the anodic oxidation in the anisotropic etching solution. By the isotropic etching thus performed, a sharp corner formed at an end portion of a recess portion formed in the Si wafer by the anisotropic etching, is rounded. Because the isotropic etching reaction progresses very slowly in comparison with the anisotropic etching, control of the etching can be made easy and accurately. As a result, the thickness of the diaphragm can be prevented from being dispersed.

Abstract: A compact apparatus for curing an uncured resin impregnated in a filter element (12) having a uniform cross-section in the longitudinal direction, and for reinforcing the filter element (12). The apparatus includes a curing pot (38) formed of outer and inner tubes (40, 42) secured integrally and coaxially with each other to form an annular space (44) therebetween, having a cross-section similar to that of the filter element (12) to be treated, for accommodating the filter element (12) therein during the curing process. A hot air circulation mechanism for forcibly supplying hot air through the filter element (12) in the annular space (44) is provided so that the temperature of the filter element (12) is effectively elevated to a value at which the curing of the resin is completed.

Abstract: An apparatus for fixing a cap (8) coated with a hot-melt adhesive on an end surface of a filter element (6), comprising a pair of vertical heating units (18, 19) installed in position (A) and an adjacent pair of vertical cooling units (20, 21) installed in position (B). The heating units (18, 19) comprises a pair of heaters (25, 29), each displaceable close to and away from the other so as to nip and release a pot assembly (9) accommodating the filter element (6) to be treated therebetween. The cooling units (20, 21) comprises a pair of coolers (30, 31) subjected to a similar movement. First, the pot assembly (9) occupies position (A) and is subjected to a heat treatment by the nip of the heaters (25, 29), causing melting of the hot-melt adhesive of the cap (8), and then transported to position (B) and subjected to a cooling treatment by the nip of the coolers (30, 31), causing solidification of the molten adhesive.

Abstract: The filter element of the present has a plurality of wavy portions which are so arranged that a plurality of wavy portions make a generally ring like structure. In order to reduce the pressure drop when the fluid flows through the filter element, the present filter element has a special shaped radial gaps. Namely, the width of a first radial gaps, which is formed within adjacent wavy portions and which connects with an inner space formed at the center of the generally ring like structure, increases from the outer end thereof to the inner end thereof. The width of a second radial gap, which is connected with outer atmosphere, decreases from the outer end thereof to the inner end thereof. Both axial ends of the wavy portions are covered with the adhesive sheet on which adhesive layer is cladded.
