Filed: 1993-12-27
Abstract: PURPOSE:To provide a neutron irradiation device which can preclude a target material such as liquid lithium from being overheated to go into seething, when a specimen is irradiated with neutrons emitted with implantation of charged particles into the target material, and which can emit neutrons continuously. CONSTITUTION:In a film state, a target material (liquid lithium) 1 is left flowing down within a reaction tub, and accelerated charged particles (d) such as deuteron are made incident on the reaction tub and implanted to the target material 1 so that it 1 makes a nuclear reaction with the charged particles (d), and thereby neutrons (n) are emitted to ahead the reaction tub, and therewith a specimen 10 is irradiated. To vary the implanting point on the target material 1 with the charged particles (d) periodically, a swinging mechanism 11 such as an electric magnet, etc., is installed for periodically swinging the track of charged particles (d) made incident on the tub, and also a movement mechanism 12 to move the specimen pereiodically in synchronization with the operation of the swinging mechanism 11 is furnished to located the specimen arranged ahead of the tub always ahead in the neutron emitting direction.

IPC: H04N9/77
Filed: 1990-11-30
Abstract: PURPOSE:To make the expansion of a detection range of a moving vector and the reduction of the circuit scale compatible by using a digital band pass filter so as to calculate the spatial gradient of a picture density. CONSTITUTION:The detector is provided with a band pass filter(BPF) 11 to obtain a smoothing differentiation in the horizontal direction, that is, the spatial gradient in the horizontal direction after smoothing processing, a low pass filter(LPF) 12 to decode a smoothed picture, and a BPF 23 or the like to obtain the spatial gradient in the vertical direction after smoothing processing. The BPFs 11, 23 are used to apply the differentiation in the horizontal direction and the vertical direction to obtain a spatial gradient after the 2-dimensional LPF arranged with respect to an input picture, that is, the synthesis after the arithmetic operation by a linear high pass filter(HPF). Thus, the smoothing processing is simplified and de-convolution to eliminate a high pass filter 11 is applied to a 2-dimension matrix in which a spatial gradient after the smoothing processing is set thereby decoding a picture after the smoothing processing and the decoded picture is used to calculate a density difference (d). Thus, a large detection range is obtained with a small circuit scale.

Abstract: PURPOSE:To attain simple video recording reservation by discriminating automatically whether or not a television program list is stored and setting a data to display it on a screen. CONSTITUTION:A video recording reservation command by a user is inputted from a video recording reservation command section 7 and a program list data management section 8 of a video recording reservation setting section 9 retrieves a storage content of a program list data storage section 6 by this input. When a television program list of a channel selected is stored in the program list data storage section 6 while the user gives a video recording reservation command, a data representing it and to be displayed on a screen is set to a display control section 10 and when not stored, a data representing it and to be displayed on a screen is set to the display control section 10 to implement succeeding video recording reservation command by a user. Furthermore, the display control section 10 converts the set data into a data displayed on the screen actually (RGB data) and outputs the resulting data. Thus, simple video recording reservation is implemented without giving confusion to the user.
