Title: Shift guiding device
Inventor: NEGISHI MASATO
IPC: H02K41/02
Filed: 1988-01-22
Abstract: PURPOSE:To permit the transfer with high precision by connecting the stator or rotor of a linear with the first or second shift body through a spacer and a heat insulating member. CONSTITUTION:A Y-stage 10 is floated up from a surface plate 15 by feeding air into a static pressure pneumatic bearing 12, and shifted in the Y-direction along the fixed guides 16a and 16b by two linear motors 100. An X-stage 14 is floated up from the surface plate 15 similarly in case of the Y-stage 10, by feeding air into static pressure pneumatic bearings 13 and 14, and shifted in the X-direction by a linear motor 200, using the side surface of the Y-stage 10 as a guide. When the X-stage 11 and Y-stage 10 are shifted, a joule's heat is generated by the electric current which flows in the coil (e.g., coil 5) of the linear motor, and each temperature of the movable elements 4a and 4b and stators 2a and 2b is raised by the Joule's heat. However, since the heat transmission to the contiguous X-stage 11, Y-stage 10, and the surface plate 15 is prevented by the insulating members 7 and 9, the temperature rise of these members can be effectively prevented.

Title: Manufacture of slow wave circuit structure of traveling wave tube
Inventor: SATO MANABU
IPC: H01J23/24
Filed: 1992-01-27
Abstract: PURPOSE:To eliminate the dislocation likely at the time of cooling hot fitting of a helix combination structure to a vacuum vessel by fixing the terminal part and fastening the central part which has a gradually greater dimension difference. CONSTITUTION:Vacuum vessels 19, 27 and a helix combination structure P are so constructed that the central part dimensional difference between the bore of the vacuum vessels and the contour of the structure P is gradually greater than the dimension difference between the positions of a high frequency input terminal part 16 and output terminal part 24 of delay circuits 11, 12. The vacuum vessels 19, 27 are heated and expanded, and after the structure P is inserted inside thereof, they are cooled upon deciding the relative positioning of the delay circuits 11, 12 at the terminal part 16 or 24. Accordingly the relative position of the terminal parts 16, 24 is decided precisely to prevent the generation of dislocation and application of unreasonable contractive force locally, which eliminates the risk of degradation of dimensional and position accuracies and deterioration of the high frequency characteristics. Therein first the terminal parts 16, 24 are fastened, and then the central part is fastened.

Title: Duplex tube
Inventor: MIHARA KEIJI
IPC: B32B27/00
Filed: 1993-01-28
Abstract: PURPOSE:To suitably use a duplex tube as a piping material for fluid such as pure or superpure water by forming an inner layer of poliphenylensulfide resin layer and an outer layer of chlorination vinyl chloride. CONSTITUTION:An outer layer 1 is formed of chlorination vivyl chloride resin, and an inner layer 2 is formed of normal chain type poliphenylensulfide. The poliphenylensulficle resin layer forming the inner layer 2 is extended to fold back an right end part 21, or only the outer layer 1 at the tube end is cut and removed to fold back the inner layer 2. In the case where a tube end is protected by the poliphenylensulfide resin, and a duplex tube is connected by butt thermal welding method, since the chlorination viyyl chloride resin forming the outer layer 1 does not protrude inside the tube in the form of a bead, this welding method is desirable. Thus since the outer layer 1 displays heat resistance and high rigidity, and the inner layer 2 checks the elution of organic substance and metallic ion, the duplex tube can be suitably used as a piping material for pure and superpure water.

Title: Electric rotating machine
Inventor: YAMAZAKI MASAHIDE
IPC: H02K5/22
Filed: 1994-02-04
Abstract: PURPOSE:To facilitate parts control and reduce the man-hour of assembling and manufacturing. CONSTITUTION:A terminal block 1 which also serves as a wire presser is formed by integrating a terminal block part 1a and a wire presser part 1b with each other. Comparison of this with a structure formed by a conventional technique which a terminal block and a wire presser are formed separately shows that the number of parts to be used can be reduced, thereby facilitating parts control. By incorporating the wire presser part 1b of the terminal block part 1 which also serves as a wire presser into a frame 2, the terminal block part 1a is also necessarily installed on the frame 2, thus reducing the man-hour of assembling. By the terminal block part 1a and the wire presser part 1b are integrated with each other, separate manufacture of them is eliminated, so it is possible to facilitate the manufacture.

IPC: G05B19/05
Filed: 1991-01-10
Abstract: PURPOSE:To correctly grasp the changing state of a desired signal by tracing the ON/OFF states of the signal in an optional timing. CONSTITUTION:A program executing means 3 carries out successively the ladder program stored in a program storage area 1. An instruction of an address (n+3) is identical with 8 trace instruction TRACE 5, and traces the ON/OFF states of the signal contained in the net of the front stage of the net including the TRACE 5. That is, a trace executing means 4 stores the ON/OFF states of signals A, B and C in the bit areas 2a, 2b and 2c of a trace signal storage area 2 respectively when the means 3 carries out the TRACE 5. Thus the ON/ OFF states of a desired signal is correctly grasped when a trace instruction is inputted right after the signal.
