An electrically-heated catalytic converter comprises a catalyst support which produces heat when electric current is applied, a holding mat made of an electrical insulating material, the holding mat being provided so as to cover an outer circumference of the catalyst support, and a case which houses the catalyst support and holds the catalyst support via the holding mat. The catalytic converter treats gas flowing in the case by a catalyst supported on the catalyst support. The holding mat has a water-absorbing property. An insulation layer made of an electrical insulating material is provided between the case and the holding mat.

In this manufacturing method, when a plurality of planetary shaft main bodies are arranged at even intervals around a sun shaft main body, a state in which a sun threaded section is engaged with each of planetary threaded sections is referred to as a regular assembled state, and an assembly formed by a combination of the sun shaft main body and the planetary shaft main body in the regular assembled state is referred to as a first assembly. The first assembly is assembled in a state in which the relationship of the planetary shaft main body and the sun shaft main body is in correspondence with the relationship of the planetary shaft main body and the sun shaft main body in the regular assembled state.

A rotation/linear motion conversion mechanism provided with an annular shaft, a sun shaft arranged inside the annular shaft, planetary shafts arranged around the sun shaft, and a first gear mechanism and a second gear mechanism, which transmit force between the annular shaft and the planetary shafts. Each planetary shaft includes a first planetary gear, which configures part of the first gear mechanism, and a second gear, which configures part of the second gear mechanism. The planetary shaft is configured to permit relative rotation between the first planetary gear and the second planetary gear.

There is provided a rolling die and a method for forming a thread or worm and a spline having a small number of teeth whose number is thirteen or less simultaneously by rolling. By use of rolling dies, the formation of a worm by rolling by use of a thread rolling die starts, and after that, the formation of a spline having a small number of teeth by rolling starts by use of a spline rolling die while continuing the formation of the worm. Accordingly, a rolled material can be rolled forcibly by a driving source from the worm rolled using the thread rolling die. As a result, the spline having a small number of teeth whose number is thirteen or less can be formed by rolling onto the rolled material at the same time as the formation of the worm.

A position detecting apparatus for an actuator includes a linear movement mechanism in which a magnet is provided; a coil which is provided so as to face the magnet such that a magnetic field is formed between the coil and the magnet; and a drive shaft which is connected to the linear movement mechanism through a ball screw, and which is linearly moved in response to rotational movement of the rotor, the rotational movement being caused by energizing the coil; and a magnetic flux detection sensor which detects a change in magnetic flux of the magnet, the change being caused by the rotational movement of the rotor, and which obtains an amount of linear movement of the drive shaft based on the detected change in the magnetic flux.

An electrically heated catalyst apparatus includes a carrier, a pair of surface electrodes, a wiring and a plurality of fixed layers. The carrier is formed of ceramics on which a catalyst is carried. The pair of surface electrodes face each other and are extended in an axial direction of the carrier on an outer peripheral surface of the carrier. The wiring is formed into a pectinate shape and is configured to supply electric power from an outside of the electrically heated catalyst apparatus to the surface electrode. The plurality of fixed layers is configured to fix the wiring on the surface electrode. The electrically heated catalyst apparatus is formed so that the carrier is electrically heated through the surface electrode. Elongation of the wiring is 15% or more.
