IPC: H01L21/321
Filed: 1989-12-14
Abstract: PURPOSE:To make an interval between bumps in the same row small, to make the bumps highly dense and to prevent a short-circuit defect to be caused when adjacent leads come into contact with each other by a method wherein two or more kinds of bumps whose height is different are used as bumps for external connection use. CONSTITUTION:The following are formed: first bumps 2, for external connection use, which have been formed at the peripheral edge of a substrate 1; and second bumps 3, for external connection use, which have been formed at the inside of the first bumps 2 and whose height is higher than that of the first bumps 2. First leads and second leads 5, 6 which are connected to the first and second bumps 2, 3 are formed. In this case, the difference in height between the first bumps 2 and the second bumps 3 is made larger than the thickness of the leads to be connected. Thereby, when the leads are connected to the bumps which are highly dense and whose interval is narrow, the interval between the adjacent leads can be set to a definite value or higher in addition to the height direction; it is possible to prevent the leads from being adjacent; it is possible to eliminate a short-circuit defect to be caused when the adjacent leads come into contact with each other.

Title: Garbage treating device
Inventor: KAGAMI YOZO
IPC: B09B5/00
Filed: 1994-12-27
Abstract: PURPOSE: To reduce requirement for resistance to heat with respect to a fan and restrict the leakage of smell during operation by arranging the fan at the upstream side of a passage for circulation. CONSTITUTION: A fan F and a heating source 3 are arranged at the upstream side of the branch point of an exhaust-passage in a passage 2 for circulation sequentially from the upstream side. When heat is generated from the heating source 3 and the fan F is operated, gas in a drying chamber 1 is sucked into the passage 2 for circulation by the sucking effect of the fan F and, accordingly, the inside of the drying chamber becomes the condition of negative pressure. The temperature of the gas is risen by heating through the heating source 3 at the downstream side after passing through the part of the fan F. Accordingly, the gas is heated by the heating source 3 after being discharged out of the fan F whereby heat, generated from the heating source 3, will never be affected directly on the fan F.  According to this method, requirement for resistance to heat of the fan F can be reduced and the leakage of smell can be restricted even when an opening and closing lid 11 is opened during operation.

Abstract: PURPOSE:To enhance the strength of a core material without spoiling the holding property of an electronic-component chip by a method wherein a bone part for the core material is formed in such a way that, in its cross-sectional shape, both end parts of a face faced with the inner circumferential face of each holding hole are provided with cut-off shapes as compared with the central part. CONSTITUTION:A holder 11 is provided with a holder body 13, composed of an elastic body, which is provided with a plurality of holding holes 12 which individually receive a plurality of electronic-component chips one by one and which elastically grip and hold the individual electronic-component chips in a state that the chips have been received. The holder body 13 is filled with a core material 14, composed of a rigid body, which reinforces the holder body 13. The core material 14 gives bone parts 15 which are passed through individual circumferences of the plurality of holding holes 12 in the holder body 13. Each bone part 15 for the core material 14, in its cross-sectional shape, forms a sharp protrusion in the central part of a face faced with the inner circumferential face of each holding hole 12 of the bone part 15. Since the protrusion 16 exists, both end parts of the face faced with the inner circumferential face of each holding hole 12 of the bone part 15 give cut-off shapes as compared with the central part.

IPC: H05K5/02
Filed: 1991-11-14
Abstract: PURPOSE:To enhance vibration-deadening performance and prevent rubber from yielding by a method wherein a vibration-proof supporting leg, which is produced by integrating two different rubbers having different hardnesses, is mounted to a vibration-generating apparatus such as printer or the like. CONSTITUTION:A vibration-proof supporting leg is mounted onto the bottom of the box 11 of a printer. A board 12, onto which mechanism parts such as an internal motor and the like are fixed, is fixed to the upper part of the vibration-proof supporting leg. The vibration-proof supporting leg has a first rubber 1 and a second rubber 2 made into an integral body. A metal fitting 3 is provided between the first rubber 1 and the second rubber 2 and a metal fitting 4 is provided on the top surface of the second rubber 2. Since tire first rubber 1 supports the weight of the printer 10, the first rubber 1 is made harder than the second rubber 2. Accordingly, against the vibration developing in the board 12, the second rubber 2 shows vibration-deadening performance. The first rubber 1, which supports the weight of the printer 10, prevents the rubbers from yielding. The permanent compressive strain of the first rubber 1 is set to be smaller than that of the second rubber 2.
