Title: Conductive adhesive tape and cathode-ray tube using the same
Inventor: LEE SANG HOON
IPC: C09J7/38
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To improve the mutual current-carrying property of an explosion-proof band and a transparent conductive film and absorb electromagnetic waves generated from a deflection yoke by forming an adhesive conductive film layer containing a conductive material and an acrylic resin on one surface of an insulating film layer and thereby shielding the electromagnetic waves. SOLUTION: An insulating film layer 21 and an adhesive conductive film layer 22 are formed, the insulating film layer 21 is formed by including an extreme infrared- ray radiating substance such as bio-ceramics in a heat-resistant polyester resin, and the conductive material contained in the adhesive conductive film layer 22 is formed from graphite or conductive metal powder. If the conductive material is graphite, nickel is preferably also included as a conduction supporting material. Because it is difficult to form a low resistance film having a resistance value not more than several tens of Ω/cm2 in the case of graphite, a metal thin film layer 23 is formed between the adhesive conductive film layer 22 and the insulating film layer 21 in order to lower the resistance value further.  A conductive adhesive tape composed of the insulating film layer 21, the adhesive conductive film layer 22 and the metal thin film layer 23 constitutes an electromagnetic wave absorbing means and can provide a sufficient electromagnetic wave shielding effect.

IPC: H01L21/06
Filed: 1993-06-30
Abstract: PURPOSE:To make a distance interposed between the external base of a bipolar transistor and its emitter short, by injecting into its intrinsic base region the ions for forming its external base while utilizing as a mask a resist pattern used in case of the formation of its emitter electrode. CONSTITUTION:An impurity (boron) is injected into an intrinsic base region 3 while a resist pattern 8 used in case of the formation of an emitter electrode 6A is utilized as a mask, and an external base 9 for a leading-out electrode is formed in the intrinsic base region 3. This process is forced to be included in the producing process of a bipolar transistor. In this manner, the alignment of the mask is not required when the external base 9 is formed. Therefore, the number of the alignment process using an element isolating oxide film 2 can be reduced from conventional two times to one time. As a result, the margin required in case of the alignment is made half, and when the external base 9 is formed, the boron ions can be injected into certain places which are close to an emitter region 7. Thereby, the bipolar transistor wherein the distance interposed between its external base 9 and its emitter 7 is made short can be realized.

Abstract: PURPOSE:To measure the shape of the surface of an object with high resolution by forming a heterodyne interference means in two stages, and detecting the change of a focal point as the phase change with high resolution by one of the heterodyne means. CONSTITUTION:The light generated from a linearly polarizing laser is converted to a double frequency laser wherein a P wave frequency is orthogonal to an S wave frequency by a first heterodyne interference means, and divided into two, then introduced into a second and a third heterodyne interference means.
