Title: Electronic parts
Inventor: TSUMORI MASAHIKO
IPC: H01L23/31
Filed: 1986-02-07
Abstract: PURPOSE:To avoid fluctuation of electronic characteristics of electronic parts by a method wherein a buried member whose linear expansion coefficient is different from the linear expansion coefficient of a resin layer is buried in the surface part of the resin layer. CONSTITUTION:An IC chip 2 and an island 3 are molded as a whole with a resin layer 4 made of molding resin such as epoxy system resin. A buried member 5 made of a material such as copper, iron, nickel and ceramic which has a linear expansion coefficient alpha1 smaller than the linear expansion coefficient alphaM of the molding resin of the resin layer 4 is buried in the upper surface part of the resin layer 4. When an IC package 1 is taken out of a molding die and cooled down to a room temperature, the resin layer 4 is contracted. As the thermal linear expansion coefficient alpha1 of the buried member 5 is smaller than the thermal linear expansion coefficient alphaM of the resin layer 4, both ends of the resin layer 4 is warped downward and the center of the curvature of the warpage is positioned below the lower surface of the resin layer 4. With this constitution, the tensile stress induced in the resin layer 4 by the warpage is cancelled with the compression stress in the resin layer 4 so that the pressure applied to the IC chip 2 can be reduced and the fluctuation of electric characteristics can be avoided.

Filed: 1989-02-06
Abstract: PURPOSE:To prevent any filament double in a package inmost layer part as well as to prevent a filament release failure from occurring by changing a periodic variable pattern of traverse speed according to yarn layer thickness of a package. CONSTITUTION:Traverse speed V is set within the range of (n-1)/2<WL/2piRV <n/2 only when yarn layer thickness (t) of a package is within the range of 0<=t<=0.005D. Where, t = package yarn layer thickness mm, D = filament fineness d, w = winding speed cm/min, pi = circumferential ratio, R = package radius cm, V = traverse speed cm/min, L = traverse stroke cm, and n = optional positive integer. Thus, in the yarn layer thickness of the package, traverse speed and change width can be set so as not to let a wind number N be the positive integer and integer + or -1/2 in a package inmost layer part, so that any ribbon lap is kept back and a release failure is prevented from occurring.

Title: Device for fixing travelling ring to rotary drum
Inventor: BERUNAA YAKOBU
IPC: F27B7/22
Filed: 1991-01-30
Abstract: PURPOSE: To prolong service life of a running ring while simplifying assembly and replacement thereof by preventing contact wear between the inner circumferential surface of the ring and the supporting surface of a rotary drum using a special strap at the time of fixing the running ring to the outer circumference of the rotary drum, e.g. a rotary kiln. CONSTITUTION: Inner circumferential surface 5 of running rings 2, 3 is secured to the supporting surface 12 of a rotary drum 1 by means of straps 18 arranged at least on one side of the running ring at an interval in the circumferential direction. The strap has an axially outward protrusion 20 including a holding face 21 facing the radially inward protruding face 6 of the running ring wherein each protruding face or holding face extends obliquely in the direction of the rotary shaft of the rotary drum from the running ring. Since the holding face of each strap abuts against the protruding face of the running ring, inner circumferential surface of the running ring is pressed locally against the supporting surface of the rotary drum by means of the strap.

Title: Illuminating device for liquid crystal
Inventor: KOMANO SHOICHI
IPC: G02F1/1335
Filed: 1993-02-17
Abstract: PURPOSE:To make brightness distribution on a liquid crystal display board uniform by arranging light scattering material in a scattered dots state on the front surface of a reflection sheet and making the brightness distribution different between an end on a light source side and a center so that the brightness distribution at the front part of a diffusing sheet may be inclined from the end on the light source side to the center. CONSTITUTION:The liquid crystal display board 10 receives the effect of temperature rise by the light source 12, and the transmissivity of the display board 10 in the case of a negative type is different between the vicinity of the light source 12 and the vicinity of the center, and the transmissivity on the light source 12 side becomes higher. Then, the irregular reflection of light by the light scattering material 15 arranged on the back surface of a light transmission plate 11 is different between the light source side and the center side. As to the brightness on the front surface of the diffusing sheet 13, it is darker on the light source side than the center side. Therefore, the brightness distribution is inclined from the end on the light source 12 side to the center. Thus, the brightness distribution on the display board 10 is made uniform by adjusting the brightness distribution on the front surface of the sheet 13 in accordance with the change of the transmissivity even when the transmissivity of the display board 10 is changed.
