A cup holder for a conventional beverage cup that has a generally inverted frusto-conical side wail and an upper access opening surrounded by a radially outwardly extending peripheral bead adapted to be connected to a disposable lid by a snap fit within a downwardly and radially outwardly depending peripheral skirt on the lid. The insulated cup holder includes a double walled insulating vessel including an inner liner and an outer liner spaced therefrom to define an insulating space and snugly receives a conventional cup so as to insulate the contents of the cup to assist in maintaining its temperature at a desired level.

A method of manufacturing a scroll member for a compression mechanism installed in a scroll compressor includes a casting step and a cutting step. An iron casting is formed in the casting step, which includes a spiraling part. The iron casting obtained in the casting step is cut during the cutting step in order to obtain a final shape of the scroll member. The iron casting may include a fixed part having a central portion with a first axial thickness and an external periphery portion with a second axial thickness larger than the first axial thickness before the cutting step. A dimension of a specified portion of the spiraling part may be larger before the cutting step is performed than after the cutting step is performed, with the specified portion preferably disposed toward an external periphery of the spiraling part.

Difficulties in retaining can holders in conventional vehicular drink holders are eliminated in a vacuum insulated can holder that includes a cup-shaped metallic outer liner having an upper opening, an opposite bottom and a generally cylindrical side wall extending upwardly from the bottom to the opening. A similarly configured cup-shaped metallic inner liner is nested within the outer liner and spaced therefrom to define vacuum space between the two. The outer liner has an outer diameter just less than the inner diameter of a conventional vehicular beverage holder while the inner diameter of the inner liner is just greater than the outer diameter of a conventional metal beverage can.

There is disclosed a lubricating oil composition for automatic transmissions which comprises a base oil comprising at least one oil selected from the group consisting of a mineral oil and a synthetic oil each having a specific kinematic viscosity and a % CA; (A) a non-boron based succinic acid imide (e.g. polybutenylsuccinic acid imide) and a boron based succinic acid imide each in an amount of 0.1 to 5% by weight based on the whole composition; (B) a condensation product of a branched chain fatty acid having 8 to 30 carbon atoms (e.g. isostearic acid) and an amine (e.g. tetraethylene-pentamine) in an amount of 0.05 to 2% by weight based on the same; and (C) a dialkyl hydrogenphosphite (e.g. dioleyl hydrogenphosphite) in an amount of 0.1 to 1% by weight based on the same, and optionally at least one member selected from viscosity index improvers, antioxidants, metal deactivators, defoaming agents, detergents, extreme pressure agents and rust preventives. The lubricating oil composition mentioned above is enhanced in the capacity of transmission torque, excellent in the performance of preventing shudder, and prolonged in the service lifetime of shudder prevention and capacity of transmission torque.

A scroll compressor includes fixed and movable scrolls, each scroll having a spiral lap placed on one surface of a plate. The lap of the fixed scroll and the lap of the movable scroll are interlocked to form a compression chamber between the laps of the scrolls which are adjacent to each other. At least one of the laps has a spiral shape in which a base radius of an involute decreases as a winding angle increases in a region extending from a winding start part to a winding middle part, and the base radius of the involute in a region extending from the winding middle part to a winding end part is larger than the smallest value of the base radius of the involute in the region extending from the winding start part to the winding middle part.

An insulated beverage container includes an outer container having a generally cylindrical inner wall (24), an outer wall (22) spaced from the inner wall and together therewith defining an insulating space (26). A vacuum is pulled in the insulating space (26) and an access opening (34) is provided at the top of the outer container. A plastic ring (30) is mounted on the outer container about the access opening (34) and has a shoulder section (34) overlying the top of the outer container and a downwardly extending sleeve section (32) integral with the shoulder section and embracing the outer wall (22). An inner container (12) formed of a material selected from the group consisting of glass, plastic and ceramics is nested within the outer container (10) through the access opening and has an open top (16) extending out of the access opening and an outer surface contacting the ring (30).
