Title: Drive unit for nc table
Inventor: KIMURA TATSUO
IPC: B23Q5/56
Filed: 1988-04-27
Abstract: PURPOSE:To correct backlash quantity in high precision by constituting a device so as to compare a load detected by a load detecting means with a set value stored in a memorizing means, and to stop a present position memorizing means from renewing present position information when load is less than the set value, in consequence of the comparison. CONSTITUTION:When a table is in a backlash, necessary load to drive a feed screw member is not increased so much, therefore load is measured through detecting voltage of driving electric power supplied to a motor 26 from a driving circuit 25 with a voltage detector 28. When the very detected load is, on being compared with a set load that has been memorized beforehand as a set value, less than the set load, a RAM 22 is made to stop renewing present position, and in a case other than that, the RAM 22 memorizes present position of a table as renewing. Therefore, it is possible to detect backlash condition surely for correcting error arising on present position information of the table, even if quantity of backlash is changed according to position of the table, or if quan tity of backlash is changed due to wear on the feed screw member or driven member.

Title: Facility for dry storage of radioactive substance
Inventor: KUMAGAI NAOKI
IPC: G21F9/36
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To lessen the intervals between placed housing tubes without increasing the pressure loss of the air flowing in a storage room by suspending the housing tubes above the vertex of an isosceles triangle whose base is perpendicular to the direction along the linkage of an air inlet to an air outlet on a face of the storage room and whose vertex angle is larger than a specific angle. SOLUTION: Housing tubes 7 are placed in a regular arrangement in a fuel storage room 3. In other words, the housing tubes 7 are located there so that an isosceles triangle 16 whose base is perpendicular to the direction along the linkage of a cooling air inlet to an outlet when the centers of adjacent housing tubes are connected to each other can be drawn on a floor of the fuel storage room 3. Moreover, the vertex angle 17 of the isosceles triangle 16 is set at both a smaller degree than the angle where the pressure loss of cooling air 15 flowing around the housing tubes 7 suddenly increases and more than 60 deg.. Consequently, intervals between the installed housing tubes 7 in the direction along the linkage of a cooling air inlet to an air outlet are shortened, with the cooling efficiency in the housing tubes 7 and the pressure loss of the cooling air 15 virtually unchanged.  Therefore, the whole area of this facility 1 can be downsized.

Abstract: PURPOSE:To measure the diameter of a particulate by changing the wavelength of laser, emitting the laser on the carrying path of particulates, and detecting the wavelength of the laser which is absorbed by the particulate. CONSTITUTION:Light is emitted from a variable wavelength laser 6 which is oscillated in a visible or ultraviolet region. The light passes through a lens 2. A part of the light is reflected from a half mirror 3. Then, the light is made to pass through a lens system 2 and a spectroscope 7 and detected by a detector 4. Thus the reference light for the intensity of light is obtained. The light which is transmitted through the half mirror 3 is made to pass through a particulate carrying path 5 and absorbed by the particulates. The light which has passed through this region passes through a lens system 2, and the wavelength is selected in a spectroscope 7. Then, the light is detected by a detector 4. At this time, a CCD camera which can measure the image is used for the detector 4, and information concerning to the individual diameters of the particulates which are distributed in the space is obtained. The wavelength of the light which is absorbed by the particulate is obtained by scanning the wavelengths of the laser light. The diameter of the particulate can be obtained based on the absorbed wavelength.
