Title: Manufacture of lead clad steel strip
Inventor: MATOBA SATORU
IPC: B23K20/04
Filed: 1987-03-30
Abstract: PURPOSE:To easily obtain a thick lead clad steel strip by polishing the joining surface between a lead strip and a steel strip and forming the inlet tension on only the steel strip and not adding the tension to the lead strip to perform the cold rolling while superposing the lead strip on the steel strip. CONSTITUTION:At the time of manufacturing the lead clad steel strip 3 connecting the lead strip 1 to the steel strip 2, the ordinary cold-rolled steel strip or the tinned steel strip or the galvanized steel strip is used at the steel strip side and the tension is given to only the steel strip side at the inlet side of rolling mill 4 at least to perform the cold rolling. In this case, the joining surface between the lead strip and the steel strip is polished by paper brush rolls 5 provided at the inlet side of the rolling mills 4 and the lead strip is superposed on the steel strip to perform the clod rolling. By this method, the thick lead clad steel strip is easily obtained.

Abstract: PURPOSE:To form a thin ornamental film having reddish color by forming an Fe2O3 layer of a specific thickness on the surface of a base material having metallic luster. CONSTITUTION:The surface of an ornament made of Al, stainless steel, Cu, Au, TiN, etc., is polished, and an Fe2O3 film is formed to 0.2-1mum thickness on the surface of the above base material having bright surface with high reflectivity by an electron beam vapor deposition method, an ion plating method, a sputtering method, etc. An incident light (i), such as sunlight, is made incident from the surface of the above film, and then, a part of the incident light (i) is reflected as reflected light (a) at the surface of the Fe2O3 layer and the rest is passed through the Fe2O3 layer, reflected at the bright surface of the base material, and passed through the Fe2O3 layer again so as to be formed into reflected light (b). Since the color tone of the reflected light a+b is changed from bright red to dark red according to the change in the thickness of the Fe2O3 layer, the thin film having various shades of reddish color can be formed on the ornament.

Title: Inductor type generator
Inventor: MUTOU OSAMU
IPC: H02K19/24
Filed: 1983-04-27
Abstract: PURPOSE:To improve the efficiency of a generator by mounting a shortcircuiting ring on an auxiliary pole, and generating a magnetic flux for a reaction which cancels a leakage magnetic flux by a current generated at the ring. CONSTITUTION:An auxiliary pole 26 is formed between a pair of inductor poles 8 of a rotor side. A shortcircuiting ring 29 is mounted on the pole 26. Since a leakage magnetic flux 32 is concentrically passed through the pole 26, a voltage is generated at the ring 29 provided on the pole 26, and a current is flowed. A reaction magnetic flux 33 is generated by a current flowed to the ring 29. This magnetic flux 33 is reduced with the result that the leakage magnetic flux 32 is reduced since part of the flux 32 is cancelled.

Title: Thermal head
Inventor: SHINYA TADAO
IPC: B41J2/345
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To lower the probability of damaging a protective film layer upon mixture of foreign matter without increasing the manufacturing cost of a head by shaping a heater such that the heating element part having a specified interval projects from the electrode step part toward the recording medium side and a heat concentrating part is formed at the central part of a heating element upon power supply. SOLUTION: An interval L is set to satisfy a relation H2>=H1, where H1 is the height from the surface of a ceramic board 1 to the step Y of a protective film layer 6 and H2 is the height from the surface of the ceramic board 1 to the top of the protective film layer 6. Distance between the step Y and the center W of projection is lengthened so that the central part of the heating element projects farter than the step Y toward the recording medium side and a cut 3b is made in the central part of a heating element part 3a. Clamping pressure of a thermal head and a platen concentrates to the center of the heating element part, the step Y recedes from the center W of projection and the angle to the sub-operating direction decreases thus lower the probability of damaging the protective layer 6.

Title: Boiler pressure part corruption detector
Inventor: IIDA MASAMI
IPC: F22B37/42
Filed: 1995-03-31
Abstract: PURPOSE: To prevent detection accuracy from being deteriorated owing to deposition of scattered matter in a furnace onto an opening of a sound locater pipe, and preventing false detection due to deterioration of a function of a sound wave detector upon long term use by inputting a closure detector circuit into which there are inputted outputs of a detector/rectifier and a correction instruction unit, and supplying a purging fluid to the sound locater pipe. CONSTITUTION: A closure detector circuit 23 receives outputs from a detector/ rectifier 06 and a correction instruction unit 29a and transfers the outputs to a monitor unit 07a and a purging opening/closing valve (solenoid valve) 25. An air piping 8 and the purging opening/closing valve 25 serve as purge means. The closure detector circuit 23 judges, when the output of the detector/rectifier circuit 06 is less than a threshold, that the opening of the sound locater pipe 02 is closed with ash and slug, etc., to partly shield sound waves. It outputs the judgement to the purging opening/closing valve 25 and the monitor unit 07a. The purging opening/closing valve 25 is opening owing to the signal. Thus, purging air is injected to remove deposite.
