Abstract: PURPOSE:To provide superior corrosion preventing properties to a steel material by forming a porous Fe-Zn alloy film on the surface of the steel material and further forming an aqueous chromate film on the porous films so as to fill the pores in the porous film and to coat uniformly the surface of the porous film. CONSTITUTION:A blasting material made of an aggregate of separate particles each obtd. by depositing Zn or a Zn alloy around an Fe or Fe alloy nucleus with an Fe-Zn alloy layer in-between is projected on the surface of a steel material to form a porous Fe-Zn alloy film. An aqueous mixture contg. 0.1-5g/l chromic acid compound and 0.01-5g/l sulfuric acid is brought into contact with the porous film and the contact is kept for 0.5-8sec to carry out chromating. By this chromating, an aqueous chromate film is formed so as to fill the pores in the porous film and to coat uniformly the surface of the porous film.

Title: Clock switching circuit
Inventor: TAKEDA KOJI
IPC: G06F1/08
Filed: 1990-09-03
Abstract: PURPOSE:To attain the switch between two optional clocks asynchronous with each other with no null time by always keeping one of two loop oscillation circuits in a halt state and then restarting the oscillation of this circuit as soon as the other oscillation circuit stops its oscillation in a clock switching state. CONSTITUTION:Two loop oscillation circuits 10 and 20 consist of loops 11-14 and 21-23 of delay elements respectively. The selected one of both circuits 10 and 20 keeps its oscillation as long as it is selected. The other oscillation circuit, however, keeps its oscillation halted. When the clocks are switched to each other, the selected and oscillated one of both circuits 10 or 20 is stopped and at the same time the other circuit 20 or 10 is started. Thus two clocks of optional frequencies can be switched to each other with no null time produced.

Title: Installation of wire tip member for installation, and wire
Inventor: SANO HIROAKI
IPC: G02B6/00
Filed: 1992-08-10
Abstract: PURPOSE:To provide a method for installing a wire by using a tip member by which the wire can be passed easily through a long-distance and small- diameter conduit line having many bent parts. CONSTITUTION:A cylindrical brush 11 is installed on a wire as a tip member. The cylindrical brush 11, with many thin hairs collected towards the circumferential direction, is fixed on the central shaft. When the cylindrical brush 11 is sent into a conduit line 2 with pressurized air, the tip member is brought into contact with an inner face of the conduit 2 by the tips of the hairs and so only small friction is caused and therefore there is small resistance during passage. When the wire 1 is moved, the hairs of the brush are inclined towards the side from which the brush is sent out and thereby friction can be reduced more. When the brush passes at bent parts, the inner side hairs bend easily and therefore a passage resistance can be reduced.
