Title: Method and device for cleaning cooling drum for casting sheet slab
Inventor: ARAI TAKASHI
IPC: B22D11/06
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent generation of surface cracks or stains on the surface of the slab by foreign matter by removing the foreign matter adhered to the circumferential surface of a cooling drum without damaging the circumferential surface of the drum in the continuous casting of a sheet slab. SOLUTION: When a molten metal pouring basin part 4 is formed by the circumferential surface of a rotating cooling drum 1, and the molten metal R fed to the molten metal pouring basin part 4 is continuously cast into a sheet slab S while it is cooled and solidified on the circumferential surface of the cooling drum 1, the foreign matter adhered to the circumferential surface of the cooling drum 1 is removed by a brush roll. In the beginning of the casting, the brush roll 5 whose element wire is 0.15-0.30mm in diameter is used. After the initial casting is elapsed, the brush roll 6 whose element wire is 0.05-0.14mm in diameter, or made of copper alloy is used, and the foreign matter adhered to the circumferential surface of the cooling drum 1 can be efficiently removed without damaging the circumferential surface of the cooling drum.

Title: Infrared spectrophotometer
Inventor: EGUCHI KINYA
IPC: G01N21/3563
Filed: 1985-08-30
Abstract: PURPOSE:To eliminate the influence of steam and carbon dioxide and obtain the IR spectra of a thin film, etc. sticking to a metal, etc. by bisecting a detection signal of IR light, passing one thereof through a potentiostat and the other through a phase regulator, synthesizing the same to one signal with an adder element and inputting the signal to a lock-in amplifier. CONSTITUTION:The IR light emitted from an IR light source 16 passes a Michelson interferometer 9', a polarizer 18 and a stress polarized light modulator 17. The horizontally and vertically polarized light subjected to the frequency modulation are alternately made incident on a sample 6 and a reference sample 7. The light reflected therefrom are made incident on a detector 8. The output from the detector 8 is inputted via a preamplifier 10 to a selector switch 11 and the potentiostat 12 respectively. The output from the switch is inputted directly or via the phase regulator 14 to an adder 13 and the output from the potentiostat 12 is inputted to the adder. The output from the adder is inputted to the lock-in amplifier 14 and is subjected to phase detection amplification in synchronization with the modulating frequency of the modulator 17. The influence of the steam, carbon dioxide, etc. is eliminated by preliminarily regulating the phase with the regulator 14 by using the sample to which the thin film is not stuck prior to the measurement of the IR spectra.

Title: Conduction transfer recorder
Inventor: ONO TADAYOSHI
IPC: B41J2/325
Filed: 1987-07-31
Abstract: PURPOSE:To obtain a conduction transfer recorder free from the breakage of an ink ribbon and superior in high-speed recording characteristics, by a method wherein the impedance of an electric current path connecting a recording electrode, a first return electrode, and a ground is made lower than that of an electric current path connecting the recording electrode, a second return electrode, and a ground. CONSTITUTION:A return electrode 19a is grounded without a load resistance, and a return electrode 19b is grounded through a resistance element 37. A recording current 34 is passed from a recording electrode 31 to a resistance substrate 32 by a recording electrode drive circuit 33 and connected to the return electrodes 19a, 19b through a conductive layer 35. Most of the recording current flows towards the return electrode 19a through the conductive layer in contact with the resistant substrate which has not been electrically heated yet. Therefore, the conductive layer 35 having no damage is always fed under the return electrode 19a, which prevents an excessive heat generation due to current concentration in the resistant substrate 32; and the breakage of an ink ribbon 21. Because the recording current return path has a two-way construction, an equivalent load resistance is reduced in comparison with a one-way path; thus, a drive voltage can be reduced.

Title: Camera capable of trimming photography
Inventor: HATA YOSHIAKI
IPC: G03B7/00
Filed: 1985-08-29
Abstract: PURPOSE:To reduce the defocusing of a print by outputting a trimming signal when a trimming photograph is taken by a camera capable of trimming photography, and controlling a diaphragm to a smaller aperture than in normal photographic mode and also recording the trimming photography on a film. CONSTITUTION:The camera is made capable of mode switching so as to take a picture in normal photographic mode and photograph a narrower trimming range. Then, when the trimming photography is not performed, a wide photographic lens B1 is photographed on a film by a photographic lens 20 and then a print is made. When the trimming photography is performed, a narrower photographic range B2 is photographed. Then when a trimming mode is selected, a trimming signal is outputted and the stop is controlled automatically to a smaller aperture than in normal photographic mode and information indicating that the trimming photography is performed is recorded on a film. Thus the diaphragm is reduced, so the depth of field is made shallow to prevent the defocusing and blur of the print.

On the other hand, the calcium carbonate 16 is pulverized by a pulverizing machine 40 to form the fine powder 41 of about 70 microns. This fine powder is introduced into the agitating reactor 39. The concd. sulfuric acid 12 from the absorption column 10 and the fine powder 41 of the calcium carbonate 16 from the pulverizing machine 40 are brought into direct reaction to form the gypsum 24' in the agitating reactor 39.  This gypsum is dried by a drier 42 to obtain the product gypsum 24. As a result, the need for a slurry vessel for the calcium carbonate and a thickener colunm is eliminated.
