Patent JP-H10178248-A (JP)
Title: Circuit board
Inventor: TOKUMOTO JUNJI
IPC: H05K1/11
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To reduce the heat capacities at terminal sections in a circuit pattern by providing constrictions which suppress the heat conduction between the terminal sections and wiring sections connected to the terminal sections between the terminal and wiring sections. SOLUTION: Constrictions 6 are provided between terminals A-D and wiring sections 5 so as to suppress heat conduction to a pattern 9 from the terminals A-D, with the constrictions 6 between the terminals A and B and the sections 5 being provided with wavy sections 7 formed by bending the constrictions 6 several times. Since the widths of the heat conducting paths for diffusing heat given to terminals sections 4 become narrower and the heat radiation through the circuit pattern 9 is suppressed, the temperature rise efficiency at the terminal sections 4 can be raised. In addition, since the lengths of the constrictions 6 between the terminals A and B and the wiring sections 5 at a unit linear distance are made longer by providing the wavy sections 7, the flowing of heat in such a pattern as a solid pattern having a high heat radiating effect is further suppressed.  It has been proven that no detect occurs at the time of soldering the slightly thicker terminal C for connecting the pattern 9 and solid pattern connecting terminals A and B from measured soldering temperatures.

Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to minimize plasma etching damages on a semiconductor substrate, by etching an oxide film using a mixed gas of fluorocarbon- based gas and a carbon oxide-based gas in a plasma etching step. SOLUTION: A field oxide film 2 and a gate electrode 3 are formed on a silicon substrate 1, and an oxide film 4 is formed thereon. In a dry etching step, the oxide film 4 is etched to form a contact hole with a mixed gas made up of a fluorocarbon-based gas, such as C2 F6 or C4 F8 , and a carbon oxide-based gas, such as CO or CO2 . In this case, a ratio of the carbon oxide-based gas to the fluorocarbon-based gas is in a range from 0.05 to 20, and a composition ratio of carbon to fluorine is below 1:3. Then, an outline of the contact hole can be formed accurately under control while a marginal space is ensured for the following step, and contact resistance is reduced. At the same time, damage to a semiconductor substrate is reduced to a minimum in the contact etching step.

Title: Data protective information superimposing signal and device using it
Inventor: KITAURA HIROSHI
IPC: H04N9/79
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To restrict copy by generating a signal upon which data protective information that is set below a specific amount of image signal maximum absolute value amplitude is superimposed at a position where it is temporally not superimposed on a blue signal horizontal synchronizing signal, also after a vertical synchronizing signal start position and in a negative direction of amplitude to a temporal position in a vertical interval. SOLUTION: In normal display, when an image 0.7Vp-p, i.e., a composite signal receives an image signal of the sum of 1.0Vp-p in a negative direction of 0.3Vp-p like an NTSC television signal, there is 0.3Vp-p in a negative direction, i.e., 43% margin. Copyright protective information is superimposed upon the margin part. Though a superimposing period is within a vertical interval and blanking which cuts off electronic beams on a CRT is applied, because there is variation of depth of the cutoff, a superimposed signal is overlapped in a negative direction so that it may not appear on a screen.
