IPC: H05K3/24
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To omit the etching process of a conductive coating film, by eliminating the conductive coating film by eliminating the surface of a substratum under the conductive coating film except an electroplated part. SOLUTION: A conductive coating film 3 composed of a palladium sulfide coating film is formed on the surface of a substratum composed of insulator. Plating resist 4 is formed in a part except a desired conductive pattern. By electroplating, a conductor layer 5 is formed in a region except the part coated with the plating resist 4. The plating resist 4 is peeled off. The conductive coating film 3 in the part except the region where the conductor layer 5 is formed is eliminated. Since the conductive coating film 3 is thin and does not completely cover the surface of the substratum 1, the surface can be dissolved. By dissolving and eliminating the surface of the substratum 1, the conductive coating film 3 can be eliminated. Thereby the etching process of a conductive coating film which has been necessary in the conventional technique can be omitted.

Abstract: PURPOSE:To reproduce in sound that does not contain peak sound using an ordinary reproducing device by modulating non-sound information of M-bit unit division, replacing lower M bits of N-bit quantized sound information with non-sound information, and transmitting or recording. CONSTITUTION:Supposing that the least significant bit of 4-bit data obtained from a transmission system is Bi=[b (i, 0)], an input to an exclusive logical sum arithmetic unit 14 is Bi and an output of a 1 clock delay unit 13 is Bi-1. The exclusive logical sum of these inputs is taken, and as Bi=[a (i, 0)+b (i-1, 0)], the output Ei of the exclusive logical sum arithmetic unit 14 becomes Ei=Bi+Bi-1=[a (i, 0)+b (i-1, 0)]+[b (i-1, 0)]=[a (i, 0)], and original data on non-sound information is obtained. On the other hand, even when all bits of information from the transmission system are applied to a DA converter 11, sound information out putted through a low pass filter 12 is reproduced as sound that does not contain peak sound as the frequency spectrum of the least significant bit is flat.

Title: Antibacterial metallic coating having high corrosion resistance
Inventor: CHIYOU SHIKOU
IPC: C25D15/02
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To obtain antibacterial metallic coating having high corrosion resistance by using metallic Ni or an Ni-Cr alloy as a matrix and dispersing Ti oxide therein. SOLUTION: As Ti oxide contained in this alloy coating, limitation is not particularly placed, but titanium dioxide is suitable since it is easily obtainable and is excellent in antibacterial effect. The content of the Ti oxide is preferably regulated to 0.05 to 5wt.%. In the case its content is less than the above range, substantial antibacterial effect can not be shown. On the other hand, in the case it exceeds this range, not only both the antibacterial effect and the effect of corrosion resistance are saturated, but also the adhesion of the coating rapidly deteriorates. Thus, by dispersing the Ti oxide by the content in the above range, the antibacterial effect can be shown over a long period, and its elution to the using environment caused by the corrosion thereof can exceedingly low suppressed.
