Filed: 1990-09-06
Abstract: PURPOSE:To prevent the deposition and growth of dust on the inner surface of a nozzle hole by passing a high-pressure gas through a passage in a diffuser plate and injecting the gas into the inside close to the lower end of the hole to form an upward spiral flow. CONSTITUTION:When a waste gas is passed through a diffuser plate 5 in a prereducing furnace for a long time, dust deposits on the inner surface of the hole 6 and on the lower surface of the plate 5. The hole 6 is formed by a metallic cylinder 8 embedded in the diffuser plate main body 7. A high-pressure gas of N2, etc., is passed through a passage 10 in the plate 5, and injected into the inside close to the lower end of the hole 6 from a gas injection hole 9. Since the injection hole 9 is directed upward and horizontally deflected with respect to the center of the cylinder 8, the injected gas forms an upward spiral flow and flows toward the upper part of the hole 6. Consequently, the dust deposited on the inner surface of the hole 6 is stripped off and removed.

Title: Method for calibrating wavelength of spectrophotometer
Inventor: SAKAI MASUMI
IPC: G01J3/06
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To realize a high wavelength trueness with use of an inexpensive mechanism part. SOLUTION: In the method for calibrating a wavelength, the periodicity of angle trueness errors of a rotary driving mechanism is measured beforehand (S1). Single or a plurality of light sources for radiating a bright-line spectrum group of a smaller wavelength distance than a wavelength distance corresponding to a half angle distance of a minimum cycle are prepared (S2, S3). A wavelength in the vicinity of the bright-line spectrum is scanned with use of the light sources and a conversion table of theoretically calculated wavelengths and the number of driving pulses of a stepping motor (S4, S5). The number of actual pulses when a subject bright line is obtained is obtained corresponding to a wavelength of the bright line and stored in an internal RAM (S6).  When a necessary measurement is completed for all bright lines, a calibration formula for calibrating the number of pulses is calculated on the basis of the data and stored (S8, S9). In an actual spectrometry, the number of pulses to a desired wavelength is obtained with use of the conversion table and calibration formula.

Abstract: PURPOSE:To prevent a slip in a friction engaging device by detecting a discrepancy in correspondence of a rotary speed between rotary members in the upstream and downstream sides of the friction engaging device and reducing an engine output when the discrepancy exceeds a predetermined limit. CONSTITUTION:In an electronic control unit 4, clutches C1 to C4 and brakes B1, B2 are selectively engaged through a hydraulic control device 3 to speed- change an automatic transmission 2 in a desired speed change shift. Here by detecting generation of a discrepancy corresponding to speed change ratio between an input shaft speed from a torque converter T/C detected by a turbine speed sensor 5 and an output shaft speed detected by an output shaft speed sensor 6, when a value of the discrepancy exceeds a predetermined permissible limit, a slip of not less than a predetermined amount is decided to be generated in a friction engaging device of the automatic transmission 2, and an output of an engine 1 is automatically reduced. Thus by preventing the slip in the friction engaging device, durability of the automatic transmission can be improved.
