The present invention relates to a method for producing an alkali cellulose with suppressed decrease in the degree of polymerization as well as with small use amount of a basic compound, and to a method for producing a cellulose ether by using the alkali cellulose thus obtained. Provided by the present invention are: (A) a method for producing an alkali cellulose, comprising Step 1 wherein a cellulose-containing raw material (I) is treated by a pulverizing machine thereby obtaining a cellulose-containing raw material (II) which contains a cellulose having crystallinity in the range of 10 to 55% and Step 2 wherein the cellulose-containing raw material (II) obtained in Step 1 is added by a basic compound with the amount thereof being in the range of 0.6 to 1.5 mol relative to 1 mol of an anhydroglucose unit that constitutes the said cellulose as well as by water with the amount thereof being in the range of 20 to 100% by mass relative to the said cellulose thereby obtaining the alkali cellulose; and (B) a method for producing a cellulose ether by reacting the alkali cellulose produced by the foregoing production method with an etherification agent.
摘要:
An acceleration sensor is installed in an electronic cassette. The acceleration sensor detects a shake. When magnitude of the shake, measured using the acceleration sensor, is greater than or equal to a shake detection threshold value, a judging circuit of a shake detecting section turns off a switching element. An operation switching section is disconnected from an irradiation detecting section that detects a start of X-ray irradiation. Thus, an irradiation detection function of the irradiation detecting section is disabled. After a predetermined time, the judging circuit outputs an ON signal to the switching element to turn on the switching element. Thereby, the irradiation detecting section resumes the irradiation detection.
摘要:
A radiographic image capturing system includes a radiographic image capture device, a radiation irradiation device, and a control device. The radiographic image capture device is capable of wired and wireless communications, and is capable of fluoroscopic imaging in which radiographic images are successively captured at notified synchronization timings or at a predetermined frame rate. The radiation irradiation device irradiates radiation toward the radiographic image capture device during fluoroscopic imaging, with continuous irradiation or pulse irradiation. The control device includes a wireless communication unit, a wired communication unit, and a controller that, if communication with the radiographic image capture device is performed by the wireless communication unit, prohibits fluoroscopic imaging with pulse irradiation in which the synchronization timings are notified to the radiographic image capture device and radiation is irradiated from the radiation irradiation device in pulses matching the notified synchronization timings.

A radiographic image capturing system includes an image capturing apparatus for applying radiation to a subject, a radiation detecting apparatus for detecting radiation transmitted through the subject, a power feeder for supplying electric power contactlessly to a contactless power receiver of the radiation detecting apparatus, a feeding-state determining unit for determining whether power-feeding by the power feeder is being performed or not, and a signal generator for generating an image-capturing inhibition signal for inhibiting radiographic image-capturing by the image capturing apparatus if the feeding-state determining unit judges that the power-feeding is being performed.
摘要:
When a first image capturing apparatus installed in an image capturing room is selected and a power supply switch of a radiation converter used in the first image capturing apparatus is turned on, a controller generates an image capturing apparatus identification signal for specifying the image capturing apparatus, and sends the identification signal together with ID information of the selected image capturing apparatus stored in an ID memory to a console in the image capturing room via a transceiver by wireless communications. The console reads image capturing conditions for the selected image capturing apparatus from an image capturing condition storage unit, and supplies the conditions to a radiation generator for recording a radiographic image in the radiation converter. The radiation generator controls a radiation source according to the supplied conditions to emit radiation for recording a desired radiographic image on a radiation conversion panel of the radiation converter.
摘要:
An electronic cassette has a casing that houses a radiation converter thereinside. The radiation converter detects radiation from a radiation source that has been transmitted through a subject, and converts the radiation into radiographic image information. Plural handles are disposed on the casing of the electronic cassette, so that a person can grip the plural handles and carry the electronic cassette. Thus, the person can grip and carry the electronic cassette while dispersing the weight of the electronic cassette, so carrying the electronic cassette becomes easy. Further, when the person loads the electronic cassette into a shooting table or the like, the person can grip either of the plural handles and load the electronic cassette. For this reason, handling of the electronic cassette becomes easy.
摘要:
A portable radiographic imaging device includes an operation unit, a controller, and an execution unit. The operation unit is operated when a target function is selected from plural different functions relating to radiographic image capturing. When a first condition, that expresses that a predetermined region has been placed at a predetermined placement portion, is established, the controller carries out control such that a function that should be effective when the first condition is established is selected. When a second condition, that expresses that the predetermined region is not placed at the placement portion, is established, the controller carries out control such that a function that should be effective when the second condition is established is selected. When the operation unit is operated, the execution unit executes a function that is controlled by the controller to be selected.
