Title: Multistable electromagnet
Inventor: KAMITSUBARA TSUNEO
IPC: H02K37/14
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To effectively reduce cocking force so as to materialize smooth revolution and increase the rotational driving force at the time of current application, by forming the end face in circumferential direction of the projecting magnetic pole face of the permanent magnet of a rotor by the incline slanting at a specified angle in the circumferential direction. SOLUTION: A permanent magnet 3, which has projecting magnetic pole faces being magnetized to different poles at equal pitches in circumferential direction through a disclike magnet support, is fixed to the shaft 2 provided rotatably within a housing 30. Here, each end face in circumferential direction of each projecting magnetic pole face of this permanent magnet 3 is made of an incline slanting at a specified angle in circumferential direction. Hereby, the revolution can be smoothed and also the driving torque at the time of current application can be increased, by effectively reducing the magnetic attraction, that is, cocking force caused by the magnetic flux between the stator magnetic pole face 5 and the projecting magnetic pole face of the permanent magnet 3 opposed through minute space to the stator magnetic pole face 5.

Title: Manufacture of optical fiber composite overhead earth wire
Inventor: SUZUKI TAMEZO
IPC: H01B5/08
Filed: 1991-10-30
Abstract: PURPOSE:To prevent an aluminum-coated steel wire from becoming loose, by stranding up the aluminum-coated steel wire over an outer periphery of a dummy wire and reforming the resulting wire assembly, once loosening it thereafter, and again stranding it up over an outer periphery of an optical fiber unit containing metallic pipe. CONSTITUTION:A dummy wire 21 such as an aluminum wire is supplied to a center of a future overhead earth wire, and a plurality of aluminum-coated steel wires 17 are stranded up over an outer periphery of the dummy wire 21. The dummy wire 21 containing stranded wire thus obtained is passed through a post former having a plurality of rollers, and is fastened from an outer periphery thereof so as to conduct reforming thereof. That is, a sufficient fastening force is applied thereto so as for the steel wire 17 not to become loose, thereby conducting reform-processing, and then the dummy wire containing stranded wire 27B thus obtained is taken up onto a drum. Then, the stranded wire 27B is drawn out from the drum and is caused to travel, and the steel wire 17 is once untwisted at a midway thereof. Thus, the dummy wire 21 at the center is taken out and an optical fiber unit containing metallic pipe 15 is instead supplied to the center. Thus, the steel wire 17 is again stranded up over an outer periphery of the metallic pipe 15. This prevents crushing of the pipe 15 and loosening of the steel wire 17.

Title: Avoiding system for congestion in variable speed network
Inventor: TOKURA NOBUYUKI
IPC: H04L47/20
Filed: 1994-12-14
Abstract: PURPOSE: To effectively avoide the congestion by providing an inter-network connection device at a point where the variable speed network are connected to each other to change the packed acceleration or the upper limit value of packet acceleration ratio into the value corresponding to the variable speed network on the transfer destination side. CONSTITUTION: When a congestion prediction signal detection circuit 7 of a variable speed terminal equipment 1 detects a congestion prediction signal, the packet transmission speed of the output packet flow of a buffer 4 is reduced by the control of a LAN packet flow control circuit 5. At the same time, a congestion prediction signal detection circuit 23 of an inter-network connection device 20 detects that the congestion prediction signal inserted by a relay node device 2 contained in a WAN is included in a received packet and notifies a WAN packet flow control circuit 22 of this fact. The circuit 22 reduces the packet transmission speed of the output packed flow of the buffer 21 in response to the notification received from the circuit 23. Thus the congestion avoiding control is attained.  When the number of stored packets of the buffer 21 increases, a congestion prediction signal is sent from the device 20. So that the overflow of the buffer 21 can be avoided.

Title: Ball screw
Inventor: HIGATANI MASAHIRO
IPC: F16H25/22
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To increase the capacity of axial load. SOLUTION: When an axial load is applied in the direction of the arrow, and gradually increased, release of pre-load occurs on the side of a ball nut 6 by axial elastic deformation of a screw shaft 2, a ball 4, ball nuts 6, 8, etc., to cause an axial clearance X. The size of the axial clearance X at this time, falls in the range of 0.2×10-3<X/Y<1.0×10-3 in relation to the diameter Y of the ball 4. Since the amount of pre-load is set to the range of 0.5 to 1% of dynamic rated load (light pre-load), the state of release of pre-load can be early obtained. When an axial load is further applied to this state, the axial clearance X in the ball nut 6 is decreased by axial deformation of the screw shaft 2, the ball 4, the ball nuts 6, 8, etc., and soon a ball circulating path comes into contact with the ball 4.  Thus, the axial load is supported on both sides of the ball nut 8 and the ball nut 6.
