When the contactors 4 are so placed on base steel 1 so as to contact with its surface and are oxidized in a heating furnace of a high temp. oxidative atmosphere, the oxide film 2 formed on the base steel and the oxide film formed around the contactors 4 are united together to one body in the stage of growth. While the steel is held at a prescribed temp. in the heating furnace, the handle 3a is pulled to strip the oxide films and the adhesive strength thereof at each temp. is measured. Since the contactors 4 have the projections, they have large contact areas with oxide films and stick firmly to the base steel. When the contactors are peeled, the films are peeled over a relatively wide range, thus the adhesive strength of various kinds of steels is measured easily and accurately.

Title: Transmission system of difference-encoded signal
Inventor: OOSHIMA TOSHIO
IPC: H04N19/60
Filed: 1983-09-06
Abstract: PURPOSE:To prevent discontinuance of signals by sending out input signals to plural transmission lines in the unit of group after they are difference-encoded and continuing the decoding of the encoded signals by using previous groups or other groups even when signal discontinuance or error occurs in the course of sending out. CONSTITUTION:Input signals IN are AD-converted 1 and disassembled into groups by making difference-encoding 2 on them. The signals are inputted into line interfaces 3 and 4 in the unit of group through plural transmission lines and sent out to transmission lines 5 and 6 after a line synchronizing signal is added to each group. At a decoding section signals of each transmission line 5 and 6 are impressed upon line interfaces 7 and 8 and decoded signals are obtained by means of a difference decoder 9 after extracting picture data and checking errors in the transmission line. When an error is detected, the difference decoder 9 prevents discontinuance of signals by switching the interfaces 7 and 8 or again using previous groups and continues its decoding operation. Therefore, signals are not discontinued completey although they are deteriorated more or less. This transmission system is ideal for the transmission of TV signals and sound signals.
