Title: Corrosion resistance for pump
Inventor: OZAKI TOSHINORI
IPC: F04D29/22
Filed: 1979-11-02
Abstract: PURPOSE: To prevent the pump from environmetal brittle cracking, by applying a plating to the part of an impeller where it is fitted with a pump shaft.  
     CONSTITUTION: Treatment as follows is applied to the inner surface of a bore formed in the boss of the impeller, for instance, of a seven-stage turbine pump having a diameter of 250ϕ. That is, the crominum plating of a thickness of 150μm is applied at first. Then, an SUS403 sleeve having a 150μm thick cromium plating on its internal surface is fitted into the bore formed at the boss of the impeller. Here, the shot peening treatment is applied beforehand to the plated surface. Further, a cromium plating having a thickness of 150μm is applied after heating the plated surface to 750°C by way of high-frequency heating and cooling the same by oil after keeping the plated surface at 750°C for 10min. By thus applying platings to the coupling part of the impeller, it is enabled to prevent the environmental brittle cracking of the pump.

Inventor: SUGII HIDETO
IPC: E05D7/04
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To simplify door fitting adjustment by fixing a removable hinge to a frame through an adjusting plate, and keeping the position of the whole from being changed even if a fixing bolt is loosened at the time of fine-adjusting the screw in the lateral direction. SOLUTION: In fitting a rotary door to a piece of furniture or the like, a fitting main body 6 is fixed to the parent body, and a hinge fitting plate 7 is fitted thereto through an adjusting plate having a bent part 9a. A cylindrical part 13a of a door side hinge is inserted in the cylindrical body 7a of the hinge to install a door in such a manner as to freely turn. In the case of fine-adjusting the hinge (cylindrical body 7a) in the lateral direction according to the fitting condition of the door, the fixing bolt 11 is loosened and an adjusting bolt 10 is operated to move the cylindrical body 7 right and left, taking the bent part 9a as a fulcrum. The longitudinal direction is adjusted by projecting and recessing the fitting plate 7 and the vertical direction is adjusted by turning an adjust bolt 16 by a driver or the like.  Thus, even if the adjusting bolt 10 is loosened, readjustment is not needed. Accordingly, adjustment work can be performed in a short time.

The top ends of plural vertical  frames 5 are inserted into the insertion holes of the upper rail 1, and bottom ends are inserted into  through holes 4 of the lower rail 2. Next, the jig 8 is inserted from the bottom end of the vertical  frame 5, and at first, the top end of the vertical frame 5 is expanded inside the upper rail 1 in  order to form the large diameter bulge 6 by which the vertical frame 5 is rigidly combined with  the upper rail 1. Then, the jig 8 is brought down, and the bottom end of the vertical frame 5 is expanded inside the lower rail 2 in order to form the large dismeter bulge 7 by which the vertical  frame 5 is rigidly combined with the lower rail 2. Since the present method does not depend on  the welding, the rust hardly generates, and the highly reliable joint part can be obtained with  superb appearance.

Title: Controller for ac exciting synchronous machine
Inventor: YOKOTA HIROSHI
IPC: H02H7/06
Filed: 1988-06-10
Abstract: PURPOSE:To prevent the rotating speed of an AC exciting synchronous machine from abnormally rising at the time of a set power abrupt change or a system trouble or the like by reducing the control gain of a cycloconverter if the rotating speed of the machine rises its specified speed or more, and returning the gain of the cycloconverter to its normal set value if its speed falls its specified speed or less. CONSTITUTION:An automatic load regulator 6 or 15 controls the secondary excitation cycloconverter 4 of an AC exciting synchronous machine 1 in response to a deviation between an output set value P0 and the power value P of the machine 1. On the other hand, a guide vane is controlled by a deviation between guide vane openings GVO and GVO0 responsive to a deviation between a rotating speed command N0 and a rotating speed N. Here, when the rotating speed is a specified speed or more, the regulator 15 is selected, the control gain of the cycloconverter 4 is reduced, while when it is the specified speed or less, the regulator 6 is selected, and the control gain of the cycloconverter 4 is returned to its normal value.

Abstract: PURPOSE:To conduct the air transport of components effectively under a simple mechanism, by making control members controlling the delivery number of components, perform their original component number control, and at the same time, making them perform the function of blocking stoppers which prevent the reverse flow of transporting air. CONSTITUTION:Both control members 3, 4 advance together into the inside of a component supply pipe 2, and as a result, the 1st and 2nd nuts become unable to be moved. Hereupon, the 2nd control member 4 retreats and makes the nut 1 fall down and immediately makes an advance again, and then, the passage of the component supply pipe 2 comes under the condition of a complete closure, and air from a nozzle 11 against the nut 1 that has fallen down, does not flow reversely to the upper part, and acts upon the nut 1 effectively, and conducts a powerful nut transport. When the 1st control member 3 retreats during this air transport, a nut is mounted on the 2nd control member 4, and when the control member 3 advances again, the 1st control member 3 is put into the inside of the screw hole of the next nut.

Filed: 1989-06-05
Abstract: PURPOSE:To attain the maintenance diagnosis in accordance with the level of responsibility of a maintenance engineer by deciding whether a command should be granted to a maintenance diagnosis executing means or not based on the access control information corresponding to a password. CONSTITUTION:Both the passwords and the access limit information are registered into a 1st memory means 13 in response to plural level identifiers showing the levels of maintenance responsibility. An access control means 16 reads a level identifier corresponding to the pass word received from a maintenance center 3 out of the means 13 and stores the level identifier in a 2nd storage means 15. Then the means 16 decides whether or not the command received from the center 3 to a maintenance diagnosis executing means 11 should be executed based on the access limit information registered into the means 13 in response to the level identifier stored in the means 15. When the execution of the command is granted, the command is given to the means 11. Thus it is possible to decide a range of the maintenance diagnostic function to which an access is possible in accordance with the level of responsibility of a maintenance engineer.

Title: Manufacture of fiber reinforced plastic article
Inventor: NAGANAMI KUNIO
IPC: B29C57/00
Filed: 1981-09-11
Abstract: PURPOSE:To obtain an article having a complicated configuration with smooth surfaces, by allowing a fiber reinforced plastic molding material, which has previously been matured to become a semi-solid state, to be continuously moved in contact with a mold having a prescribed cross sectional configuration so as to be drawn and molded, and hardening it. CONSTITUTION:The fiber reinforced plastic molding material that has previously been matured to become a semi-solid state is continuously moved in contact with the mold having a prescribed cross sectional configuration so as to be drawn and molded, and then is hardened. Thus, since the molding material that will be fed into a mold is in a less sticky semi-solid state, there is no apprehension that is will adhere to the mold inner surface, and in addition since it is liable to flow into narrow gaps in the mold, an article having a complicated configuration can be produced. Not only the molding cycle is shortened but also the process can be further automated, and an article having beautiful surfaces can be produced.
