Title: Production of sintered titanium alloy member having hollow part
Inventor: YAMAGUCHI TOSHIYA
IPC: B22F5/10
Filed: 1991-12-24
Abstract: PURPOSE:To improve the dimensional accuracy of a sintered titanium alloy member having a hollow part. CONSTITUTION:A large round bar-shaped jig 21 and a small round bar-shaped jig 22 are inserted respectively into hollow large-journal parts 11 and hollow small-journal parts 12 of a green compact molding 1. These jigs 21, 22 consist of a material having the higher coefft. of linear expansion than the coefft. of linear expansion of a titanium alloy and is hardly reactable with the titanium alloy at a sintering temp. The inside surfaces of the large-journal parts 11 and small-journal parts 12 are adhered to the outside surfaces of the jigs 21, 22 by the linear expansion of the jigs 21, 22 and the shrinkage of the green compact molding 1, by which the inside surface shapes of the large-journal parts 11 and small-journal parts 12 are corrected along the outside surface shapes of the jigs. Clearances are made between the jigs 21, 22 and the respective journal parts 11, 12 by a difference in the coefft. of linear expansion after cooling down to room temp., by which the jigs 21, 22 are easily removed.

IPC: B62M6/75
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To reinforce the foot pedalling driving force with the driving force by an electric motor later by directly friction-rotating a rear wheel tire or a front wheel tire with an electric motor for generating the auxiliary power and a cylindrical driving wheel to be rotated by the rotation driving force of the electric motor through a one-way clutch. SOLUTION: A cam handle grip is pushed forward so that a driving wheel 8 contacts with a tire at an appropriate pressure, and a power source breaker is closed. When an appropriate pedalling force is applied to a pedal, detecting signal from a pedalling force sensor provided near a larger sprocket is sent to a control circuit 7a. A speed sensor 7c for detecting the number of revolution of the driving wheel 8 detects passing of a vane of an arrow-wheel like speed detecting vane 7b, and sends the speed signal to the control circuit 7a. The control circuit 7a decides the surrent to be sent to an electric motor 6a on the basis of the pedalling force signal and the speed signal, and sends it. The electric motor 6a is thereby rotated, and the rotary driving force of an output shaft 6b is transmitted to a driving shaft 8 through a one-way clutch 5c, and the ahead power is given to the tires.

IPC: H05B41/28
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a 'soft' lighting system by providing a circuit system which contains a load circuit having a lamp and a driving circuit and operates in the vicinity of resonance by free oscillation. SOLUTION: Before ignition, the series-parallel constitution is mainly attenuated by only an iron core loss of a lamp coil L1, and therefore, a resonance circuit to which a load is slightly imparted, offers voltage in the visinity of high resonance increased for ignition. In that case, an iron core magnetic loss in the lamp coil L1 increase in about 2.5-th power of the voltage acts basically and restrictively. A frequency generator behaves as a controlled voltage source. When the voltage exceeds the ignition voltage of the lamp, the parallel part of a load circuit (having the L1) is given the effective resistance of plasma discharge converted by a winding of the lamp coil L1 as the load, and a lighting frequency is increased, and an inductance L2 acts as a current limited lamp choke coil. As a result, the frequency generator behaves again as a controlled current source.
