Title: Fixed-side wearing ring structure
Inventor: ARAKI MASANOBU
IPC: F03B11/00
Filed: 1977-11-09
Abstract: PURPOSE: A lower side fixed wearing ring dwindled the number of parts in such a way that is is made possible to disassemble in order to facilitate replacing inspection of the runner wearing ring in the water mill and the pump water mill.  
     CONSTITUTION: The structure of low side fixed wearing ring for water mill and pump water mill is made by doughnut shaped assembly, in the event of part having sectional surface sectioned off from the center of a circle, because it is a matter of course that the peripheral surface is longer than the circumferential surface, in case the peripheral surface is restricted by a discharge ring 6, there is no possibility of penetrating inside. In consequence, the disassembly and assembly of the fixed part wearing ring 15 is made very easily by inserting a parallel piece 16 having at least one piece of a parallel surface in the inside of the part sectioned off from the center of the circle. In place of using the parallel piece, making it as a taper piece can repress the inward and outward movement of each fixed wearing ring by the tolerances of the sectional surface.

Abstract: PURPOSE:To provide an isolation function unconditionally. CONSTITUTION:Diodes 11 to 14 are connected to drains of a PMOS 1, an NMOS 2, a PMOS 3, and an NMOS 4 respectively to constitute first to fourth controllable unidirectional switches. Sources of the PMOS 1 and the NMOS 2 are connected, and third and fourth unidirectional switches and a DC power source 7 are connected in series in the same direction so that sources of the PMOS 3 and the NMOS 4 hold the DC power source 7 there between, thereby constituting a close circuit where the PMOS 1 and the NMOS 2 are turned off at the time of turning-on of third and fourth unidirectional switches. Simultaneously, a close circuit where the DC power source 7 charges a capacitor 10 is constituted, and a close circuit where the PMOS 1 and the NMOS 2 are biased forward at the time of turning-off of third and fourth unidirectional switches is constituted. Thus, the isolation insulating function is unconditionally provided independently of turning-on/off of the PMOS 1 and the NMOS 2.

In this reacting tower E, NH 3  is admitted from the lower part and NH 4 OH water G is sprayed from the upper part to convert the HCl contained in the exhaust gas to NH 4 Cl. This is put into an electric dust collector H, where it is captured of incineration ash and NH 4 Cl and this put into a rotary kiln I and is heated to ≥(300W338°C). The NH 4 Cl is again decomposed to HCl and NH 3  and the incineration ash is put into an ash reservoir J. The mixed gases are admitted into a packed tower K. The HCl reacts with the CaO, CaCO 3 , Ca(OH) 2  etc. in the tower K and is removed as CaCl 2 L. The NH 3  is used by being circulated again to the reacting tower E; therefore, the removal of the HCl is accomplished at low costs.

Abstract: PURPOSE:To achieve secure separation of sheets by providing suction cups to suck the uppermost sheet of the laminated sheets and a member which is brought into contact with the tip of the lifted sheet, and forming a convex shaped part along a periphery where the member in contact with the sheet tip faces the suction cups. CONSTITUTION:A sheet separating mechanism 2 is set in the specified position of an opening part of a supply magazine 1, and a sheet (F) is sucked by lowering suction cups 21 to the front end part of the sheet (F). Then, a sliding table 13 is moved backward, and the suction cups 21 are rotated by 90 deg. clockwise around a hinge 24 in cooperation with an arm 26, a guide pin 27, and a guide groove 28. The sheet (F) is brought into contact with a contact rod 31 fitted to a risingly-supporting body plate 25. The diameter of a contact fod 31 is large except at the part corresponding to the suction cups, and the sheet (F) generates ruggedness along the contact rod 31. If there is any case of duplicate feed of the sheets, air is introduced therebetween, leading to gravity falling of the second or the subsequent sheets. The suction cups 21 are relevelled and only the first sheet (F) is fed to a carrying roller pair 3. This arrnagement allows secure separation of the sheets piece by piece.

Abstract: PURPOSE:To fasten and manufacture many kinds of screws, or to control attitude of a workpiece without change of arrangement of a device by providing a change-over device, which is moveably arranged between a frame and a case, for locking rotational motion of radially oriented shafts when a positioning mechanism is operated. CONSTITUTION:In a normal state, a positioning mechanism 8 locks rotational motion of a case 4. In this state, a main shaft 2 is rotated by driving a main shaft drive mechanism, and the rotation of the main shaft 2 is transmitted to a radially oriented shafts 5 and respective tool holding shafts 6 via gears, and makes tools 7 rotate. Then, required machining or assembling operation is performed by approaching a tool 7 to a workpiece by using a robot. On the other hand, if the positioning mechanism 8 does not operate, the case 4 becomes rotatable about the main shaft 2, and a change-over mechanism 9 operates associated with the case 4, and the rotation of the radially oriented shafts is locked. Consequently, the main shaft 2 and gears attached to it rotate, but the radially oriented shafts 5 do not rotate. Therefore, the tool holding shafts 6 do not rotate, and the case 4 only rotates about the main shaft 2, and indexing of the tool holding shafts 6 is performed.
