Title: Ladderlike partial plating method for one side of metallic rod and strip
Inventor: OKADA KOUJI
IPC: C23C2/00
Filed: 1981-10-02
Abstract: PURPOSE:To plate one side of a metallic rod or strip partially like ladder at a low cost with good efficiency by bringing a coating roll which is notched with discontinuous circumferential barrel grooves on the circumferential barrel surface into contact with the surface of a hot dipping bath and the traveling rod or strip. CONSTITUTION:An original plate 7 for plating is introduced into a plating bath with a deflector roll 5 and contacts a coating roll 4 which rotates while it is partly immersed below the bath surface 3 of the molten metal 2 in a molten metal bath 1, whereby the molten metal 2 stuck on the surface of the roll 4 is transferred onto one surface of the plate. The surface of said roll consists of the shapes in which discontinuous circumferential barrel grooves are notched in the circumferential barrel surface of the roll 4. The plate 7 receives partial plating like ladder by contacting both end parts and a part of the central part of the roll 4. After the plating, the plate 7 is conducted with a deflector roll 6 to a cooler and is cut suitably to cut plate products having the partially plating form.

Title: Reset circuit for automatic equalizer
Inventor: SHIROMIZU YASUBUMI
IPC: H03H21/00
Filed: 1986-07-04
Abstract: PURPOSE:To attain synchronization re-establishment from out of synchronism by changing a timing outputting a reset pulse based on the state of an output signal of a frame synchronizing circuit and a protection circuit so as to eliminate an unnecessary time. CONSTITUTION:A counter of the protection circuit 3 repeats set/reset frequently in the state that a signal outputted from a frame detection circuit 2 repeats normality/abnormity repetitively in the process from the synchronizing state to the out of synchronism and the count does not reach a setting value. Thus, a control circuit 3 discriminates it that an automatic equalizer 1 is not equalized optimizingly and outputs a reset drive signal from an output terminal 5c to apply immediate reset after the out of synchronism. In the state that a signal outputted from the circuit 2 shows consecutive error, the counter of the protection circuit 3 is not reset and the count content reaches the setting value. Thus, the control circuit 5 judges it as a hit or the frame out of synchronism due to a burst error and awaits the re-establishment of synchronization and outputs the reset drive signal from the output terminal 5c.
