Title: Production of magnetic material
Inventor: FUJITA HIRONORI
IPC: H01F1/059
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To produce a magnetic material improved in magnetic properties by constraining a powdered raw material composed essentially of magnetic powder within a working die and repeatedly applying compression to the powdered raw material under a constraint so that crushing is brought about. SOLUTION: For example, a magnetic powder, which consists of about 67vol.% of Sm2 Fe17 N3 powder of about 200-100μm as magnetic powder and the balance containing Zn powder of less than about 50μm, epoxy resin of less than about 50μm, etc., as coating material, is compacted. The resultant raw material 3 is disposed in a cruciform forming die 2 and constrained. The atmosphere around the raw material 3 is formed into an inert atmosphere by means of Ar gas. Then, a compressing operation, in which a couple of punches 11 is pushed in a direction A to pressurize the raw material 3, and a compressing operation, in which a couple of punches 12 is pushed in a direction B to pressurize the raw material 3, are repeated a proper number of times in succession, and forging is applied repeatedly.  By this method, magnetic properties can be made highly efficient by refining the magnetic powder and also the oxidation of the magnetic powder can be prevented.

Title: Controller for ac electric vehicle
Inventor: TAMURA HIROAKI
IPC: B60L9/24
Filed: 1991-09-12
Abstract: PURPOSE:To carry out smooth reversing by setting a second set value lower than a first set value in a DC intermediate circuit for stopping the main circuit and not stopping the main circuit, when the voltage or the DC intermediate circuit reaches the second set value, but short-circuiting the positive and negative electrodes of the DC intermediate circuit through a resistor. CONSTITUTION:A suppression voltage setter 31 sets a second set value lower than a first set value being set by an overvoltage setter 21 and when a suppression voltage detector 32 detects that the voltage of the DC intermediate circuit has reached the second set value, an operation start command is delivered through an OR element 33 to a suppression switch 17. Since the suppression voltage detector 32 delivers the operation command only to the suppression switch 17 and does not deliver the operation command to a protection signal generating circuit 23, only voltage suppressing operation is effected by means of the suppression switch 17 and a voltage suppressing resistor 18 even if the voltage of the DC intermediate circuit begins to increase during reverse starting operation and thereby the main circuit is not stopped. According to the constitution, an AC electric vehicle can be started in the climbing direction on an inclining railway.

Title: Production of high density sintered compact of stainless steel
Inventor: OTSUBO HIROSHI
IPC: C22C33/02
Filed: 1991-08-21
Abstract: PURPOSE:To prevent the occurrence of change in shape by gravity, etc., before sintering and to obtain a high density sintered compact having superior dimensional accuracy by adding specific amounts of Fe-V powder of specific grain size to a stainless steel powder of specific grain size and subjecting the resulting powder mixture to compacting and to sintering. CONSTITUTION:An Fe-V powder of 1-10mu average grain size is added to a water atomized stainless steel powder of 5-20mu average grain size so that V content in a sintered compact becomes 0.10-2.0wt.%, and the resulting powder mixture is compacted and sintered. By the above procedure, the green compact before sintering can be prevented from getting brittle and the occurrence of deformation by gravity, etc., before sintering can be prevented. As to the average grain size of the stainless steel powder to be used, manufacturing costs are increased when it is below 5mu, and, on the other hand, sintering characteristics become insufficient when it exceeds 2mu. Manufacturing costs are increased when the average grain size of the Fe-V powder is below 1mu, and, when it exceeds 10mu, the deformation preventing effect is reduced. Corrosion resistance is deteriorated when the above-mentioned content of the Fe-V powder exceeds 2.0, and, on the other hand, deformation is increased because the amount of pulverized powder acting as sintering auxiliary is decreased when it is below 0.1%.

Moreover, these magnifying factors Ki are set so that they are symmetrical to a borderline L1 dividing the number of horizontal picture elements H into approximately two right and left, or they are symmetrical to a borderline L2 dividing the number of vertical scanning lines V into approximately two up and down.  And, a transformation is provided to the number of horizontal picture elements P or the number of vertical scanning lines Q of the PDP display determined from a relational expression of a rectangular coefficient α which means an arrangement pitch form of the individual picture elements configuring a PDP of a predetermined aspect ratio different from the input picture's.

Title: Antiskid control device
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/48
Filed: 1985-10-18
Abstract: PURPOSE:To prevent the occurrence of kick back and to prevent relocking of wheels, by a method wherein a communicating passage is connected to a transmission route for a brake oil pressure through an orifice by passing it to a hold valve. CONSTITUTION:A brake oil pressure during the initial stage of control of antiskid is reduced by closing a hold valve 3 and opening a pressure reducing valve 5. Since, with this state, a gate valve 2 is substantially closed, kick back due to a fluctuation in a subsequent brake oil pressure is completely prevented from occurring. A brake oil pressure after release of a wheel from lock is repressurized through return of the pressure reducing valve 5 to a closed state and return of the hold valve 3 to a opening state. Repressurization is kept through combination of slow pressurization by an orifice 20 and rapid pressurization by opening of the hold valve 3. Namely, control of opening and closing of the hold valve 3 and the pressure reducing valve 5 discriminates the need for pressure reduction and pressurization (slow pressurization and rapid pressurization) of a brake oil pressure depending upon a wheel speed condition, and a control device outputs an electromagnetic signal responding to the discrimination.
