Title: Lead frame and semiconductor integrated circuit device using it
Inventor: MAKINO SATOSHI
IPC: H01L23/28
Filed: 1993-11-24
Abstract: PURPOSE:To increase the strength of dam bars so as to prevent the deformation of the outer lead section of a lead frame at the molding time or carrying time of the lead frame by making the width of the dam bars twice or more as broad as that of the outer lead section. CONSTITUTION:The width A of a dam bar 5 integrally formed at the middle section of a lead 4 is made twice or more as broad as the width B of the outer lead section 4b of the lead 4. As a result, the deterioration of the strength of the dame bar 5 can be prevented even when the width B or pitch of the outer lead section 4b is reduced. Therefore, the deformation of the outer lead section 4b integrally formed with the dam bar 5 can be prevented, because the deformation of the dam bar 5 is prevented even when the pressure of a molten resin injected into a metallic mold becomes uneven and a high pressure is applied to part of the dam bar 5 at the time of sealing part of a lead frame 1 with a resin. Since the leads 4 are hardly deformed even during the carrying time of the lead frame 1 also, the manufacturing yield of a QFP can be improved.

Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To eliminate any deviation of contacts and facilitate adjustment of the displacement and the contact force of the contacts by storing a plurality of elastic bodies for pinching a plurality of contacts in an inner space of an insulator. SOLUTION: Elastomers 30 or a plurality of elastic bodies are stored in the inner space 11 of an insulator 10. The elastomer 30 has a columnar shape and a contact 20 is pinched by adjoining elastomers 30 in the same row. A plurality of contacts 20 are thus pinched by a plurality of elastomers 30 so that, if the elastomers 30 are expanded or contracted by the temperature change, the adjoining contacts 20 are not affected by the dimension change in the elastomers 30 and the contacts are hardly deviated by the deformation of the elastomers 30. A plurality of elastomers 30 are independently stored in the inner space 11 of the insulator 10 so that the shape, dimension, quality, etc., of the elastomers 30 can be appropriately changed or selected.

IPC: F16K31/70
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility of a bimetal ring being struck by a valve disc and that of an outer ring valve seat being worn. SOLUTION: The valve disc 11 is positioned within a transformer chamber 4 constructed of inner and outer ring valve seats 6, 7, a protective seat 16 and a lid member 5 and an ended bimetal ring 13 is positioned on a slope part 12 between the outer ring valve seat 7 and the protective seat 16.

The valve disc 11 has an outside diameter greater than the inside diameter of the protective seat 16 and has twelve through holes 15 on its outer periphery which communicate the top to the bottom of the valve disc 11. Each of the through holes 15 is partially located between the inner and outer peripheries of the outer ring valve seat 7.  Steam passing at high speed between the outer ring valve seat 7 and the valve disc 11 can enter the transformer chamber 4 from a gap 16 between the projections 15 of the valve disc 11, so the amount of steam passing between the annular plate 14 and the valve disc 11 is reduced enough so that the annular plate 14 is less likely to be sucked upwards and the bimetal ring 13 less likely to be struck by the valve disc 11 via the annular plate 14.
