Title: Manufacture of sintered hard alloy
Inventor: SAKOJIRI HIROMICHI
IPC: B22F3/035
Filed: 1982-10-06
Abstract: PURPOSE:To improve the dimensional accuracy of products by adding a lubricant after packing hard powder and before press-molding it in manufacturing stages. CONSTITUTION:When a sintered hard alloy is manufactured by a powder metallurgical method, a lubricant is usually added before the manufacturing stages. The lubricant is liable to vaporize or sticks to the apparatus, so it can not be added by a fixed amount, and sintered hard products are extremely uneven in dimensional accuracy. In this invention, after packing hard powder in stages for manufacturing a sintered hard alloy, a lubricant such as camphor or liq. paraffin is added by about 1wt% of the amount of the filled powder, and press- molding is carried out.

IPC: B62M11/14
Filed: 1987-07-16
Abstract: PURPOSE: To increase rotational torque with a simple gear mechanism synchronously rotating a large-diameter second internal gear which is coaxial with an input gear via the meshing relation of a first planetary gear, a first internal gear and a second planetary gear with the rotation of the input gear. CONSTITUTION: When an input gear 7 is rotated by the foot operation of a pedal, a planetary gear 12 is rotated along the outer periphery. When the input gear 7 is rotated, the practical rotating radius is added with the radius of the planetary gear 12 to its radius, and rotational torque is increased by the expansion of the radius. The rotation and revolution of the planetary gear 12 are transmitted to a large-diameter internal gear 9 as they are via an intermediate planetary gear 13. The internal gear 9 and the input gear 7 are synchronously rotated, and the rotation is transmitted to the rear wheel of a bicycle via a chain wheel integral with the internal gear 9 and a chain suspended on the chain wheel 11.

Title: Control device for electric motor vehicle
Inventor: KANEDA JIYUNICHIROU
IPC: B60L3/04
Filed: 1980-12-11
Abstract: PURPOSE: To protect a main circuit device against the shortcircuit failure of a chopper at the regeneratively braking time by deenergizing a main circuit when the ratio of a field current to an output current decreases to a value lower than  a set predetermined value.  
     CONSTITUTION: When a chopper 6 is failed in a shortcircuit at the regeneratively braking time, the output current I c  of a voltage regulator 2 flows mostly through the chopper 6, with the result that the field current I f  flowing through the field coil 4 will remarkably decrease. Thus, the ratio I f /I c  of both the currents will abruptly decrease. A comparator 12 produces an output when the  ratio I f I c  of both currents decreases lower than the set value corresponding to  the weakest field rate allowed in a main motor, thereby deenergizing the main  circuit. In this manner, it can prevent the damage of the main circut device for  the shortcircuit of the chopper 6 at the regeneratively braking time.

IPC: H01L21/027
Filed: 1992-06-12
Abstract: PURPOSE: To improve a linear bearing structure by providing it with a means of lessening or preventing the movement of rotary bodies. CONSTITUTION: A improved linear bearing structure 10 is constituted of a plurality of pairs of guides (passages) for guiding rotary bodies 14 (ball bearings or rollers) which are forced to be located in a holder 12. In a typical example, two pairs of rotary bodies and a holder are used between a moving section and a fixed section. Each pair has four elastic elements (springs) 16, and the one end of each spring is fastened to the holder and the other ends of the two springs are fastened to a fixed passage or fixed section. The other ends of the other two springs are fastened to the moving passage or moving section. Due to this positioning of the springs, the springs have recovery spring forces for forcing the holder gradually to a correct traveling position.  If the holder is traveling correctly, the spring forces of the springs mutually offset each other, and there is no characteristic friction to a recovery mechanism in the recovery mechanism.
