The main body (310) is made of stainless steel, and the glass member (330) is joined to the annular extension (320) through sintering process. And a process of joining a stainless steel member and a glass member (330) by sintering is provided.

PROCESS OF JOINING STAINLESS STEEL MEMBER AND GLASS MEMBER BY SINTERING
A process of joining a stainless steel member and a glass member by sintering comprises the steps of: providing a ring member (100) of stainless steel and a glass member (101); placing the ring member (100) of stainless steel and the glass member (101) in a graphite holder (102, 103, 104) so that the glass member (101) is positioned relative to the ring member (100) of stainless steel; placing the graphite holder (102, 103, 104) together with the ring member (100) of stainless steel and the glass member (101) in a furnace; sintering the ring member (100) of stainless steel and the glass member (101); and cooling the sintered ring member (100) of stainless steel and the glass member (101). The sigh glass produced by this process has the high corrosion resistant property.

Scroll compressor with back pressure chamber cavity for assisting in start-up
A scroll compressor is provided with a cavity in its back pressure chamber to increase a volume of the back pressure chamber. In this manner, at start-up, the back pressure chamber will not be effective to bias the two scroll members together until this enlarged volume is filled with a compressed refrigerant. This reduces the load on the electric motor at start-up.
A scroll compressor assembly includes a shaft having an eccentric pin that orbits a first scroll member relative to a second scroll member. The eccentric pin has a length extending from a base end to a distal end, which defines a contact area having a slight crown that engages a slider block. The contact area is moved toward the distal end of the eccentric pin to improve the stability of at least one of the first and second scroll members.
