Abstract: PROBLEM TO BE SOLVED: To avoid cracks, breaks, or the like of a metal ball accompanied by a thermal stress, by a method wherein, in a semiconductor device in which a semiconductor and a wiring pattern are sealed, a through hole opening diameter on a reverse face to one face is set greater than that of an insulation member. SOLUTION: A flexible circuit substrate 201 comprises a copper foil 202 which is a conductive circuit pattern, and a polyimide 203 of a film thickness 60 μm which is an insulation member. Further, the polyimide 203 is provided with a through hole 214 on a taper which is narrow on a side of the copper foil 202 and expanded toward the counter side. At this time, an angle θ made between a sidewall part of the through hole 214 and a face of the polyimide 203 is set to be 60 deg.. Further, the copper foil 202 of a film thickness 18 μm in the through hole 214 of the polyimide 203 is electrically connected to a solder ball 208 as an electrode part 205. In a heat cycle durability test in a temperature region set at -25 deg.C and +125 deg.C, no cracks appear in the solder ball and excellent soldering can be performed.

Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To guide paper desirably to a carrier roller at the time of setting paper and to heighten the grip force of the carrier roller to paper at the time of image forming action so as to improve paper conveying force. SOLUTION: A setting table 11 is supported to be oscillated integrally with a first pressure roller 12, and an end part 18, proceeding toward a main roller 4, on a guide face 10 is moved along the outer peripheral surface 6 of the main roller 4 by the oscillation of the setting table 11. At the time of setting paper, the setting table 11 is therefore oscillated upward to arrange the guide face 10 almost horizontally so as to guide the paper 1 desirably to the outer peripheral surface 6 of the main roller 4. At the time of image forming action, the setting table 11 is oscillated downward to arrange the guide face 10 almost vertically so as to increase the winding quantity of the set paper 1 onto the main roller 4.

Title: Hot tension testing jig
Inventor: MAKINO TAKUMA
IPC: G01N3/08
Filed: 1993-03-11
Abstract: PURPOSE:To provide a small size hot tension testing jig that is ease of aligning work, short in test time and excellent in heat resistance. CONSTITUTION:A test piece 11, a pair of half globular collets 21, a cylindrical cap nut with a spherical inner wall 22a comining into contact with a spherical outer wall 21a of each collet 21, and a columnar shaft member 23 engaging with this cap nut 22 are all parallelly installed on the same axis. Those of globular collet 21, cap nut 22 and shaft member 23 is made up of a molybdenum alloy being high in heat resistance. Since the outer wall 21a of the globular collet 21 and the inner wall 22a of the cap nut 22 both are formed in a spherical shape each and being mirror finished, they are sliding on each other. In the case where both axes of the test piece 11 and the shaft member 23 are not accorded with each other, slight tensile force is added to an interval between them, whereby the outer wall 21a of the globular collet 21 and the inner wall 22a of the cap nut 22 are slidden with each other, so that their axes are easily congruent with each other. As a test jig is made up of a small number of part items, it is miniaturized and, what is more, a span of test time becomes shortened because of aligning work being easy enough.

Title: High-speed thin coating of plastic film
Inventor: MURAKAMI KUNIO
IPC: C08J7/04
Filed: 1983-03-26
Abstract: PURPOSE:To effect high-speed thin coating to such a degree that a rainbow pattern due to light interference does not appear, by scraping, in stages, a coating solution which is measured and applied to a high-speed running film by passing it, while still wet, through each measuring bar so that the amount of the attached solution may reach the desired level at the final stage. CONSTITUTION:A coating solution which is measured and applied to a plastic film running at a speed >=150m/min is scraped off stepwise while still wet by at least two measuring bars so that the amount of the attached coating solution may be decreased by at least 20-80% when it passes through one measuring bar and that the amount may be decreased to the desired level at the final stage, whereby it affords a thin film coating of a thickness <=1mu and it is dried. The coating unevenness can fall within + or -30% when it is measured by a light interference method by parallel white rays. It is possible to effect coating to such a degree that a rainbow pattern due to light interference does not appear and that its appearance is not injured.

Filed: 1988-03-03
Abstract: PURPOSE:To improve dimensional accuracy at the interval among solder conductors forming coiring patterns and enable to greatly omit a terminal processing procedure by continuously forming a wiring pattern film cross- directionally and applying solder covering to the wiring pattern film. CONSTITUTION:By using a conductive paint which can be used in soldering, conductive wiring patterns 3 in a variety of forms are continuously formed cross-directionally on a thermoresistant plastic film 2 of a preset width by means of printing process. Solder covering is applied to the surface of the conductive wiring pattern 3 to form the wiring pattern 3 made of a solder foil layer 5. Accordingly, the terminals 14 of the wiring pattern 3 exposed on both ends of an electric wire tape 1 or a flat cable do not require any preliminary soldering and do not bend because they are formed and fixed on the thermoresistant plastic film 2. This improves dimensional accuracy at the interval among the wiring patterns 3 and enables to greatly omit a terminal processing procedure.

Abstract: PURPOSE:To effectively supply an energy to reaction gas, raise efficiency of gas phase reaction and realize low temperature processing or prevent damage on the device by forming the internal surface of reaction furnace, which permits gas phase reaction with optical energy by supplying an object to be processed or reaction gas, to reflect such light beam. CONSTITUTION:A required reaction gas is supplied from a gas supply port 4 into a reaction tank, while the gas is exhausted from an exhaustion port 5 in order to keep the inside of reaction tank 1 at a low pressure gas ambient. Meanwhile, the side space of reaction tank 1 is irradiated with ultraviolet ray from a light source while wafer 6 is heated under low-temperature by an auxiliary heater 8 of wafer holder 7 as a subsidiary processing. Thereby, the reaction gas in the reaction tank 1 is used for vapor reaction by receiving optical energy of ultraviolet ray and a reaction object is deposited on the surface of wafer 6 in order to form a film. In this event, the ultraviolet ray which does not permeate the reaction gas and does not effectively transmit the optical energy to the reaction gas is reflected at the internal surface of reaction tank 1 and projected to the reaction gas again. Through repetition of such reflections and projections, optical energy is utilized effectively for reaction of reaction gas.

Filed: 1978-04-28
Abstract: PURPOSE: To accurately measure the potential distribution of a fluorescent lamp in a simple operation by connecting an integrating circuit with a conductive ring which is mounted movably upon the outer circumference of the glass tube of the lamp.  
     CONSTITUTION: The glass tube 2 of a fluorescent lamp 5 is wound with a conductive foil to produce a conductive foil ring 6, which is connected with an integrating circuit 9 which is composed of a register 7 and a capacitor 8 so that the integrated output is caught by an oscilloscope 10 thereby to measure the potential distribution.
