The present technology relates to a file generation device, a file generation method, a file reproduction device, a file reproduction method, and a program capable of associating an image stored is a file with external data outside the file. A file control unit generates an association-type high efficiency image file format (HEIF) file in which an image in an HEIF file compliant with HEIF and specific information that specifies external data outside the HEIF file, the external data to be associated with the image, are stored in association with each other. Furthermore, the file control unit reproduces the association-type HEIF file. The present technology can be applied to a case where an HEIF file is generated or a case where the HEIF file is reproduced.

A single-element ultrasonic sensor includes a single transducer element and transmits an ultrasonic wave on the basis of a pulse wave. An ultrasonic array sensor includes a plurality of transducer elements and receives an ultrasonic reflected wave. A pulsar supplies the pulse wave to the single element ultrasonic sensor. A receiver receives electric signals from the transducer elements included in the ultrasonic array sensor. An amplification and conversion unit amplifies the electric signals received from the transducer elements included in the ultrasonic array sensor, converts the electric signals into digital signals, and arranges the digital signals in a serial order so as to generate a serial digital signal. An image generator generates an image on the basis of the serial digital signal.

An information processing system and an information processing apparatus and method for transmitting image data from a portable terminal apparatus, to a different apparatus through a network so that the image data may be managed by the different apparatus. A camcorder image station has a folder for each user of a camcorder and has, in each of the folders, 10 sub folders of albumto albumto each of which a name is applied in advance. The user of the camcorder transmits images picked up by the user to the camcorder image station so that the images are registered into a predetermined album. The camcorder has an album list of 10 albums of albumto albumin advance and selects an album of one of the names from within the list to designate an album into which image data should be uploaded.

Information processing system, information processing apparatus, and method

The present invention relates to an information processing apparatus by which image data can be downloaded simply. A video camerareceives thumbnail images corresponding to one or more images included in an album from a video camera image stationand displays the thumbnail images on an LCD unit. If one or more images to be downloaded are selected, then the video cameraacquires image information of the selected image or images from a video camera image station, analyzes the image information and discriminates it one by one image whether or not the selected image data are downloadable. Every time one image is discriminated to be downloadable, the video cameraaccesses a corresponding URL designated for each image, downloads the image from the URL and records the image onto a recording medium. The video camerasuccessively downloads the selected images in this manner.

Provided is a process for producing a roasted coffee bean extract suppressed in bitterness by selectively reducing the content of chlorogenic acid lactones while maintaining the content of chlorogenic acids and having taste and flavor intrinsic to the roasted coffee bean extract. The process for producing a roasted coffee bean extract includes adjusting a raw-material roasted coffee bean extract so as to have a Brix degree of from 10 to 40 and a pH of from 5.5 to 6.5, and treating the extract with heat at 100&#xb0; C. or more.

Process for production of roasted coffee bean extract

A chamber having a water jet generation apparatus and a mesh installed inside is pushed against a surface of a peening object. A rotary vane of the water jet generation apparatus, disposed in a region in the chamber between the mesh and the chamber, is rotated to generate a water jet flowing toward the peening object in one region in the chamber, the one region is a region closer to the peening object than the mesh. A plurality of shotsput in the regionA moves toward the peening object along with the water jet and collides with the surface of the peening object. After the collision, the shots move toward the mesh along with the water jet. Compression residual stress is given to the surface of the peening object with which the shots have collided. Thus, spreading of contaminants peeled off from a peening object can be prevented.

Accordingly, the residual stress of the WJP object can be evaluated precisely in a shorter time.

Roasted coffee bean extract

A high-pressure water jet is injected from a nozzle scanned and a shock wave generated due to the collapse of bubbles included in the water jet is impacted on a WJP execution object. Tensile residual stress close to the surface of the WJP execution object is improved to compressive residual stress. The shock wave is detected by a pressure sensor and a shock wave generation frequency is obtained. Whether the obtained shock wave generation frequency is larger than a set value or not is decided. When the shock wave generation frequency is larger than the set value, a high-pressure pump is stopped and the injection of the water jet from the nozzle is stopped. When the shock wave generation frequency is equal to or smaller than the set value, the operation condition of the high-pressure pump is changed. The pressure of the water jet injected from the nozzle is increased and the WJP is executed for a part of the WJP execution object where the shock wave generation frequency is equal to or smaller than the set value. Improvement effect of the residual stress of the WJP execution object can be confirmed more accurately.
