Abstract
Abstract In a cradle adapted to receive a carrier, which carries semiconductor elements stored therein, for mounting the carrier on a predetermined position of a spin drier, a pair of stepped portions which are parallel to each other and perpendicular to a rear wall of the cradle is provided on the rear wall of the cradle so that leg portions of the carrier are received between the stepped portions. The stepped portions serve to prevent the leg portions of the carrier from opening during the spinning of the carrier. The cradle can thus avoid damages of the semiconductor elements stored in the carrier, which damages would otherwise be caused to occur due to opening of the leg portions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
148 words
A cradle for receiving a carrier which has leg portions and contains semiconductor elements stored therein, and mounting said carrier on a predetermined position of a spin drier, which cradle comprises a rear wall with a window therein, said rear wall having a pair of end edges and a pair of side edges, a pair of opposed end walls extending at right angles from said rear wall end edges, a pair of stepped portions extending at right angles from said rear wall side edges, an inclined wall portion extending outwardly from each said stepped portion, and a pair of opposed parallel side walls extending from said inclined wall portions, the end portions of said stepped portions and inclined wall portions being cut away to receive the corners of said carrier, the leg portions of said carrier being received between said stepped portions and restrained thereby against outward movement.
Claim 2
Dependent Claim
148 words
A cradle for receiving a carrier which has leg portions and contains semiconductor elements stored therein, and mounting said carrier on a predetermined position of a spin drier, which cradle comprises a rear wall with a window therein, said rear wall having a pair of end edges and a pair of side edges, a pair of opposed end walls extending at right angles from said rear wall end edges, a pair of stepped portions extending at right angles from said rear wall side edges, an inclined wall portion extending outwardly from each said stepped portion, and a pair of opposed parallel side walls extending from said inclined wall portions, the end portions of said stepped portions and inclined wall portions being cut away to receive the corners of said carrier, the leg portions of said carrier being received between said stepped portions and restrained thereby against outward movement.
Claim 3
Dependent Claim
25 words
A cradle as claimed in claim 1, wherein the stepped portions have been formed together with the cradle as a one-piece unit by press forming.
Claim 4
Dependent Claim
15 words
A cradle as claimed in claim 1, further comprising a window in each side wall.
Claim 5
Dependent Claim
18 words
A cradle as claimed in claim 1, further comprising means for mounting said cradle in a spin drier.
Claim 6
Dependent Claim
12 words
A cradle as claimed in claim 1, further comprising a carrying handle.
Claim 7
Dependent Claim
153 words
An assembly for carrying semiconductor elements in a spin dried comprising: (A) a carrier having means for holding a plurality of said semiconductor elements, and leg portions; and (B) a cradle for receiving said carrier comprising a rear wall with a window therein, said rear wall having a pair of end edges and a pair of side edges, a pair of opposed end walls extending at right angles from said rear wall end edges, a pair of stepped portions extending at right angles from said rear wall side edges, an inclined wall portion extending outwardly from each said stepped portion, and a pair of opposed parallel side walls extending from said inclined wall portions, the end portions of said stepped portions and inclined wall portions being cut away to receive the corners of said carrier, the leg portions of said carrier being received between said stepped portions and restrained thereby against outward movement.
Claim 8
Dependent Claim
153 words
An assembly for carrying semiconductor elements in a spin dried comprising: (A) a carrier having means for holding a plurality of said semiconductor elements, and leg portions; and (B) a cradle for receiving said carrier comprising a rear wall with a window therein, said rear wall having a pair of end edges and a pair of side edges, a pair of opposed end walls extending at right angles from said rear wall end edges, a pair of stepped portions extending at right angles from said rear wall side edges, an inclined wall portion extending outwardly from each said stepped portion, and a pair of opposed parallel side walls extending from said inclined wall portions, the end portions of said stepped portions and inclined wall portions being cut away to receive the corners of said carrier, the leg portions of said carrier being received between said stepped portions and restrained thereby against outward movement.
Claim 9
Dependent Claim
25 words
An assembly as claimed in claim 8, wherein the stepped portions have been formed together with the cradle as a one-piece unit by press forming.
Claim 10
Dependent Claim
