摘要:
A motor driving force transmission device includes electric motors which produce motor driving force with which a rear differential is operated and a speed reduction and transmission mechanism which reduces the speed of the motor driving force of the electric motors and transmits it to the rear differential. The speed reduction and transmission mechanism has eccentric cams which rotate as the electric motors are driven, transmission members which rotate as the eccentric cams rotate, and is disposed on an outer circumference of the rear differential.

A speed change gear device is provided with a housing, a first member supported rotatably about a predetermined rotational axis, a shaft member formed with an external gear, an annular member formed with an internal gear meshing with the external gear, and a transmission mechanism for transmitting a rotational component only of the annular member to the shaft member or a disc member arranged to be rotatable relative to the housing. The external gear differs from the internal gear in the number of teeth. Further, the first member is formed with a receiving hole that receives the annular member at a position where the center of the annular member is at a predetermined distance from the rotational axis. Then, the annular member is received in the receiving hole rotatably relative to the first member.

An easily structured swing internal contact type planetary gear device is proposed which can achieve a higher meshing ratio when an involute tooth profile is adapted. Each of an internal tooth of an internally toothed gear wheel and an external tooth of an externally toothed gear wheel is formed with an involute tooth profile. Under a driving condition, one of an internal tooth body of the internally toothed gear wheel and an external tooth body of the externally toothed gear wheel is elastically deformed in an extending direction and the other thereof is elastically deformed in a contracting direction so that the number of meshing teeth becomes larger than the number of meshing teeth under a non-driving condition.

A speed change gear includes: a housing that has internal gears having different inside diameters; and a plurality of change gear units that are respectively in mesh with the plurality of internal gears and that change the speed of rotation from an input shaft to an output shaft. Each of the change gear units includes a rotating member that has one of a pin protruding in a direction along an input/output axis and an insertion hole; an eccentric member that centers on an eccentric axis that is eccentric with respect to the input/output axis; and an oscillating member that oscillatingly rotates as the eccentric member rotates about the input/output axis.

A multiple fuse device for a vehicle includes a circuit board with a battery-side bus bar portion and an alternator-side bus bar portion connected together by a temporary joint portion at a position apart from a fusing portion that provides charging current protection. An insulator housing is placed over the circuit board but the temporary joint portion is left uncovered by the insulator housing. A temporary joint portion is then at least partially removed. This partial removal may leave behind two temporary joint portion remnants, one on the battery-side bus bar portion, and one on the alternator-side bus bar portion. The temporary joint portion thus enhances the strength of the circuit board while the fuse device is being manufactured, which prevents the fusing portion from being accidentally deformed or broken during the device's assembly.

A method of producing a semiconductor device having a plurality of wiring layers forms a first interlayer-insulating film, forms a plurality of grooves for wiring in the first interlayer-insulating film, fills metallic films in the grooves to form wirings, etches the first interlayer-insulating film with the wirings as a mask and removes the interlayer-insulating film between the wirings to provide grooves to be filled, and fills a second interlayer-insulating film made of a material of low dielectric constant in the grooves to be filled.
