Title: Lead-forming material and resin adhesion improved surface treatment
Inventor: NAGAI YASUMUTSU
IPC: C23C8/42
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To increase the adhesion between a lead forming material and a resin-sealing material by dipping the surface of the lead forming material in ozone water, then leaving it as it is in an atmosphere of high temperature and high humidity and thereby forming an oxide film on the surface of the lead forming material. SOLUTION: The surface of a lead-forming material made of pure copper or a copper alloy is dipped in ozone water and then is left as it is in an atmosphere of high temperature and high humidity to form an oxide film on the surface of the lead- forming material. At this time as the ozone water, pure water which includes 3 ppm or above of ozone and has a resistivity of 1 MΩ.cm or above and has a temperature of 5-35 deg.C is desirable. Shelf conditions after being dipped in the ozone water are a temperature of 50 deg.C or higher and a relative humidity of 70% or higher. Furthermore, the very important factors which affect the strength of the oxide film formed on the surface of the lead-forming material include the thickness of the oxide film. The appropriate thickness of the oxide film to be formed on the surface of the lead-forming material is 30-100 nm.  As a result, a lead-forming material which has a superior adhesion with a resin-sealing material can be obtained.

Abstract: PURPOSE:To provide a connection method through which a simple and reliable connection work is executed without needing a surplus connection part by executing connection in a way that a sealant is located between a rib-freed surface where ribs are cut off throughout a desired range and the saddle of a branch pipe. CONSTITUTION:Ribs 11 present in a range with some margin and formed in a position where the outer peripheral edge of a saddle 21 is considered to make contact with the ribs when a pipe 1 with ribs is connected are cut off from a root to form a rib-freed surface 12. A through-hole 13 having approximately the same size as that of a short pipe 22 is formed approximately in the central part of the rib-freed surface 12. The surface of the rib-freed surface 12 is coated with a sealant, such as silicone resin, butyl rubber, having viscoelasticity, and the back of the saddle 21 is pressed thereagainst for fixing. This method effects simple and reliable connection only by locating the sealant between the rib-freed surface and the saddle and prevents easy separation of a branch pipe from the outer peripheral surface of the pipe with ribs even when vibration, a shock, and bending moment are exerted on the branch pipe during a piping work.

Nextly, the resist film 5 is selectively exposed and developed to form a pattern. Using the pattern as a mask, an SOG film 4 is dry-etched to form a pattern. With the pattern of the SOG film used as a mask, an organic resin film 3 is etched by RIE using an oxygen gas. The sample is put into a plasma treatment to form an organic thin film 10. After that, the film 12 is etched by RIE using a chlorine gas, with this multilayer resist used as a mask, to form aluminum-copper alloy interconnection 12. Finally, the multilayer resist is removed by incineration. Consequently, aftercorrosion is prevented from occurring and so the formation of a deteriorated layer is avoided.

Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent an operation from being immediately stopped in the case of occurrence of an opened state of a water feeding thermistor or a short-circuited trouble by a method wherein a signal of an input thermistor is set to a predetermined value when a water feeding thermistor is troubled in its open or a short-circuited trouble occurs. SOLUTION: When a hot water feeding operation is carried out, a gas combustion amount G is calculated in reference to an equation of G=K* (TS-TW)*Q, wherein TS is a set temperature set by a temperature setting device 1 under a feed-forward control, TW is a fed water temperature detected by the water feeding thermistor 9 and Q is an amount of water detected by a water amount sensor 3. This value is controlled by a gas proportional valve 6. Then, a temperature of the fed-out hot water is detected by the fed-out hot water thermistor 10, a difference between it and the set temperature TS is corrected under a feed-back control and controlled by a gas proportional value 6. When the water feeding thermistor 9 is troubled in open or troubled in short circuit, a signal of the water feeding thermistor 9 becomes a predetermined value, for example, a value set to 20 deg.C, and the combustion amount G of gas substituted for the aforesaid calculating equation is calculated, it is controlled by the gas proportional valve 6 and then the hot water feeding operation becomes possible.
