Title: Braking force control device
Inventor: TAKEUCHI MITSUNARI
IPC: B60T8/92
Filed: 1993-12-21
Abstract: PURPOSE:To enable normal braking to be effected even when a motor is damaged by providing a disengagement means for disengaging a plunger from a plunger drive means when the plunger is returned to its initial operating position. CONSTITUTION:A first and second plunger 35, 36 are constantly energized toward their initial operating positions by first and second return springs 46, 45. When an engagement member 42 is disengaged from a first plunger 35, the plunger is returned to its initial operating position by the action of both return springs 46, 45. When the engagement member 42 is disengaged from the first plunger 35, the plunger is moved to its initial operating position by the forces of both return springs 46, 45. Therefore, even if a motor 31 fails when the first plunger 35 is driven near a position in which it keeps the capacity of a pressure control chamber 48 at a maximum, the first plunger 35 is not stopped at that position, and so normal braking is possible.

Abstract: PURPOSE:To obtain high purity metallic Nd in a simple apparatus with high productivity and operational stability by adding a transition metal to a part at which metallic Nd is accumulated under the cathode and attaining a lowered m.p. when metallic Nd is produced by electrolysis with a fluoride bath. CONSTITUTION:When Nd oxide is reduced by molten salt electrolysis with a fluoride bath to produce metallic Nd, a transition metal such as Fe is added to a part at which metallic Nd is accumulated under the cathode by 1-5 pts.wt. per 100 pts.wt. metallic Nd and electrolysis is carried out at 1050-1075 deg.C temp. of the bath near the surface of the cathode. The min. electrolysis temp. required to form and accumulate metallic Nd is just above a temp. ensuring the melting, dropping and accumulation of metallic Nd formed on the surface of the cathode, that is, the m.p. (1024 deg.C) of metallic Nd. Though it is necessary that the min. electrolysis temp. exceeds the m.p. of the electrolytic bath, this restriction can be relaxed by selecting the compsn. of the bath. Excessively high temp. or low temp. operation is avoided and operation can be carried out at a proper temp. without hindrance to tapping with high productivity.

Title: Voidless enamel winding insulating system stator winding
Inventor: HAGA KOJI
IPC: H02K15/12
Filed: 1991-12-10
Abstract: PURPOSE:To elevate the reliability on insulation by voidlessly insulating the stator coil of a high-voltage dynamo-electric machine by the hardened matter of thermosetting resin which has reacted upon a hardening accelerator. CONSTITUTION:They are voidlessly insulated by the hardened matter of thermosetting resin which has reacted upon a hardening accelerator, using expansive fleece materials being treated with hardening accelerators, as base material layers, for a slot insulating layer 13, an intercoil insulating layer 14, and a wedge 18 which constitute a slot 12 for the stator coils 16 and 17 of a high- voltage dynamo-electric machine. That is, the expansive fleece material impregnated with thermosetting resin expands to block the space between the coils 16 and 17, and also the hardening accelerator begins to melt into the thermosetting resin, and reacts upon the expansive fleece material and the thermosetting resin having penetrated into the space. Accordingly, at the point of time of impregnation treatment, the viscosity of the thermosetting resin goes up, and prevents the leakage to outside. Hereby, the reliability on insulation can be elevated.
