Abstract: A strong silicide joint between silicon carbide and a metal is resistant to fracture even at high temperature. A method for manufacturing the silicide joint is also provided. This method includes the steps of: bringing a silicon carbide-based member into contact with a Kovar (Fe—Ni—Co alloy) member; and thermally joining the silicon carbide-based member to the Kovar member.

Abstract: A constant flow valve has a chamber (6) provided therein with a first diaphragm (8) having a valve member (7), a second diaphragm (9) and a third diaphragm (10). The chamber is divided into a first pressure chamber (11), a second valve chamber (12), a first valve chamber (13) and a second pressure chamber (18). The first pressure chamber has means for applying a constant inward force to the second diaphragm, and the second pressure chamber has means for applying a constant inward force to the third diaphragm. The first valve chamber is communicated with an inlet channel, the second valve chamber has a valve seat (27) corresponding to the valve member, and the valve seat divides the chamber into a bottom valve chamber (14) communicating with the first valve chamber through a communication hole formed in the first diaphragm and a top valve chamber (15) communicating with an outlet channel.

Abstract: A small-sized vehicle achieves improved cooling performance for an electric motor of a power steering apparatus. The small-sized vehicle includes a power steering apparatus, a steering force transmission mechanism, and an engine output transmission mechanism that are mounted in this order from top to bottom, and the electric motor of the power steering apparatus is arranged such that a motor axis thereof extends along a planar surface that is substantially perpendicular to a steering shaft and the electric motor is located in a range from the left oblique rear position to the right oblique rear position of the steering shaft so as to be disposed in front of the steering shaft.

Abstract: An automatic assembly device includes a jig pallet for carrying and positioning parts used in an assembly line, and a holding device for holding fastener members used to mount the parts to assembled members. A drive is positioned between the fastener member holding device and an external driving device.

Abstract: A photo-semiconductor is produced by melting Bi.sub.2 O.sub.3 or its mixture with a small amount of an oxide or fluoride and then quenching the resultant melt in the form of a film.
