Title: Method for recovering samarium from samarium-cobalt alloy scrap
Inventor: NEMOTO HIDEKAZU
IPC: C22B59/00
Filed: 1989-07-20
Abstract: PURPOSE:To separate and recover Sm at a high yield with a simple treatment by precipitating and separating Sm as oxalate from the aq. mineral acid soln. of Sm-Co alloy scrap, taking out the remaining Sm and Co of the filtrate as a carbonate precipitate and recycling the same. CONSTITUTION:The Sm-Co alloy scrap is dissolved into hydrochloric acid and/or nitric acid to prepare the aq. mineral acid soln. and oxalic acid of approximately the equiv. to the Sm or below is added into this aq. soln. to precipitate the samarium oxalate in the state while leaving a small amt. of the Sm ions in the aq. soln. An alkali (NaOH, etc.) is added to this filtrate to adjust the pH to 3 to 5 and thereafter, the carbonic acid compd. (Na2CO3, etc.) of 0.1 to 0.6 equiv. to the Co ions is added to the soln. The soln. is treated for about 30 minutes to 3 hours at about <=25 deg.C to precipitate the carbonate of the Sm and Co which are then filtered and separated. This carbonate precipitate of the Sm and Co is returned to the next Sm-Co alloy scrap and the above- mentioned stage is repeatedly executed. The Sm is obtd. from the Sm-Co alloy scrap at the high recovery rate in this way.

IPC: B23H1/02
Filed: 1983-10-06
Abstract: PURPOSE:To prevent unusual consumption of an electrode and make the whole unit light and compact by arranging in such a way that the movement of an electrode for machining feed, etc. in the opposing directions, such as, up and down, etc., can be controlled accurately and appropriately with less time lag. CONSTITUTION:This electric discharge machine is arranged so that the interval between an electrode 5 and a workpiece 3 can be properly maintained at all times. When a main servo control 26 sends a drive signal to a main servo motor inside a supporting device 4, supplementary servo controls 27, 28 also send drive signals to motors 20, 21 which drive supplementary supporting devices 9, 10, and control is made so that these motors are interlocked with the main servo motor 8 housed in the main supporting device 4. That is, the supplementary servo controls 27, 28 send control signals to motors 20, 21 so that they interlock with the main servo motor 8, making them rotate supplementary supporting shafts 11, 12. The feed load applied to the main servo motor 8 is reduced by an amount of the feed load applied to the supplementary servo motors 20, 21, an offset load is not generated, and the interval between the electrode 5 and the workpiece 3 is always controlled for feeding with a high-speed response.

IPC: G11B21/08
Filed: 1985-08-28
Abstract: PURPOSE:To attain position control with high accuracy and with simple constitution by rotating a sensor screw to control the position within a sensor bar. CONSTITUTION:A sensor screw 128 is fitted into an attachment screw hole of a sensor bar 130. When the screw 128 is rotated, the bar 130 slides in parallel with the sliding direction of a carriage together with the screw 128 and the bar 130 attached to a sensor base part 125. Therefore, the screw 128 is rotated to control the light shielding quantity with the optical axis of a photosensor caused by a light shielding part 133 of the bar 130. Then the bar 130 is fixed at a position where the output level of the photosensor is changed. Thus the control is through with the track reference position. In such a way, a large degree of control operation is possible by a fine feed function of the screw. Then the control accuracy is improved despite a simple control action.

Title: Plasma x-ray generator
Inventor: YOSHIMOTO HIROSHI
IPC: H05G2/00
Filed: 1988-07-27
Abstract: PURPOSE:To obtain high efficiency X-ray and also lengthen the life by using a saturable reactor constituted of magnetic material, high voltage conductor and low voltage conductor for a discharge switch. CONSTITUTION:When a capacitor 2 is speedily charged by a power 1 which converts AC into DC, an exciting current flows to a saturable reactor 3A through an impedance 12. When a magnetic flux increases as the charging voltage rises with the result that it reaches a prescribed value, magnetic saturation takes place and impedance extremely lowers; as a result, a switching action takes place and the same condition as in the case where a discharging switch is closed occurs. A voltage is impressed, through a circuit impedance 4, between a high voltage electrode 7 and a low voltage electrode 8 set in a plasma generation chamber 5 through an insulator 6 to generate spark discharge or plasma between both electrodes 7 and 8. Thus, it is possible to obtain a large discharge current and also lengthen the life of the discharge switch.

Title: Eaves edge structure for house in snowfall area
Inventor: ONOZUKA KEIICHI
IPC: E04D13/072
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To prevent generation of uncomfortable sound due to dropping of snowmelt by slanting a gutter horizontally arranged below a side edge of a roof member closer to an eaves edge, along the side edge of the roof member, so as to assume the same slanting state as that of the roof member. SOLUTION: Snow having accumulated on a roof member 13 which slants at a relatively sharp pitch falls along an upper surface of the roof member 13, and then falls from the roof member 13 onto the ground below the same. In this case, a gutter 21 installed on a decorated plywood 14 at an eaves edge is horizontally arranged below the roof member 13 so as to assume the same slanting state as that of the roof member 13, and further the gutter 21 does not hardly protrude from a lower area of a side edge of the roof member 13 closer to the eaves edge, toward the outdoor side. Therefore, the gutter is free from a fear of being broken due to snow falling from the roof member 13. Snowmelt dropping into the gutter 21 is drained via a down pipe. In this manner, there is no possibility that snowmelt falls from the decorated plywood 14 at the eaves edge, along an external wall of a house.

Title: Tray type gas-liquid contact device
Inventor: TOMISAKA YASUSHI
IPC: B01D3/22
Filed: 1980-12-29
Abstract: PURPOSE:To improve tray efficiency and to increase treatment capacity by dis posing mesh-like structural members in the froth layers of the gas-liquid mixed phases on each tray in order to fine the foam in the froth layers while maintaining the superficial velocity in a gas-liquid contact column relatively high. CONSTITUTION:A gas-liquid contact column body 1 is divided to a plurality of contact reaction chambers by means of gas-liquid contact trays 2, and these are connected vertically by means of downcomers 3. Vapor ascends by passing through the opening parts 4 of the trays 2, and enters the liquid phase retained between inlet and outlet weirs 5, 6, where it undergoes gas-liquid contact. On the other hand, liquid passes through the clearance at the bottom of the downcomer 3, overflows from the weir 5, flows onto the tray 2, and overflows from the weir 6 while contacting the steam. In this case, the gas-liquid contact state is in the form of froth of gas-liquid mixed phases, and forms a froth layer A between the weirs 5, 6. The small foams (b) produced in the opening parts 4 grow to large foams B as they ascend, and the leyer A arrives at the top surface. However, there are the mesh-like structural members 7 approximately parallel with the trays 2 in the layer A and therefore the foams B are again divided into small foams (c), whereby the gas-liquid contact areas are increased.
