Title: Pretreating method for al-containing austenitic heat resistant steel to stably form uniform al2o3 film
Inventor: KADO SATOSHI
IPC: C23C22/00
Filed: 1978-03-02
Abstract: PURPOSE:To uniformly form an Al2O3 film with superior resistance to oxidation and hot corrosion on an Al-contg. austenitic heat resistant steel by throughly removing an inner oxide layer of the steel by surface grinding, etc. CONSTITUTION:An austenitic heat resistant steel contg. Al; 4.5-10%, C<0.4%, Si<2.0%, Mn<10%, Ni; 12-50% and Cr; 5-30% is worked to a plate by blooming, hot rolling, etc. At this time, since diffusion of Al from the interior of the steel is insufficient against penetration of oxygen from the surface, repair of an Al2O3 film due to selective oxidation of Al is not carried out on the steel surface and Al is oxidized in the matrix of the steel surface layer part, forming an inner oxide layer. This oxide layer is thoroughly removed by surface grinding with a belt sander. Next the plate is cold rolled to a desired thickness and used as a heat resistant plate for an annealing furnace, etc. Uniform Al2O3 is formed in a hot oxidizing atmosphere to prevent oxidation and corrosion thereafter.

Filed: 1990-02-01
Abstract: PURPOSE:To generate a fillet surface by rolling a ball so as to bring into contact with two curved surfaces at both sides of a ridge to be rounded, and generating the ridge and an apex along the line of a curve representing a locus plotted by a contact. CONSTITUTION:The ball is rolled so as to bring into contact with the curved surface at both sides of a thick line part that is all the ridges to be rounded, and the locus of the contact between the ball and the curved surface is found. Then, a new apex is generated at a part where the line of the curve representing the locus is crossed to the ridge of an original solid, and a new ridge (R ridge) is generated on the curved surface at both sides of all the ridges to be rounded so as to connect the apex along the locus of the contact. An original ridge to be rounded is deleted, and a new circular arc ridge is generated so as to connect the R ridges generated at both sides, and the apex (arrow head part) connected to only two R ridges is deleted, and two original ridges are changed to a smooth ridge. In such a way, it is possible to generate a free curved surface to connect fillet surfaces smoothly even at the apex part of the solid where the fillet surfaces are crossed with each other.

Abstract: PURPOSE:To attain the simple mass-production of a VTR or the like with multi-function and high performance by providing a head changeover switch and a means operating under non-contact state so as to connect only a head in operation selectively thereby decreasing the number of channels to a required minimum number. CONSTITUTION:In connecting a head 1 and a video circuit 6, an electronic switch 30 is thrown to the position A. Since the head 1 and the switch 30 are loaded on a rotor 16 in this case, no rotary transformer is used as a signal transmission means between the head 1 and the switch 30 and only an electric wire (j) is enough for the purpose. In connecting a head 2 and the circuit 6 further, the switch 30 is thrown to the position B and only an electric wire (k) is enough for the purpose by the same reason above. Then a channel 14 is used as the signal transmission means from a terminal C of the switch 30 to the circuit 6, a rotor coil 14a on the rotor 16 and a stator coil 14b on a stator 23 keep the non-contact state so as to send a signal.

Title: Dust collector of damper

IPC: F27D17/00
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To remove dust effectively by blowing fresh air from a dust collecting nozzle when a temperature detected value exceeds a set value after a specified time has been passed after a damper used for a pipe duct for feeding waste heat gas exhausted from a cement kiln to a waste heat boiler has been closed. SOLUTION: When waste heat gas containing dust flows from the upstream side of a pipe duct, dust is adhered to the shaft 11 of a damper and a blade 10 and, in particular, much dust 16 is accumulated around a valve seat 13. When dust 16 is accumulated, the blade 16 of the damper is closed imperfectly, and there occurs a problem that hot waste heat gas leaks and flows to the downstream side. To prevent this problem, after a specified time has been collapsed after the damper has been closed, the detected temperature of thermosensor set on the downstream side of the damper is compared with a set value and, when it is above the set value, the damper is judged to be closed imperfectly, and the solenoid valve 21 is opened, and fresh air is introduced from a dust collecting nozzle 20 around the valve seat 13 so as to blow off accumulated dust 16.
