Patent JP-S63189817-A (JP)
Title: Auto-focusing device
Inventor: ITO MASATOSHI
IPC: G02B7/08
Filed: 1987-02-02
Abstract: PURPOSE:To improve focusing accuracy while the titled device is in zooming by fixing a focus detecting time in zooming, calculating the driving speed of a correction lens and updating the driving speed every approximately fixed time. CONSTITUTION:When a zooming key 11 is turned to the wide angle side at time t0, a variable power lens 2 is moved and the correction lens 3 is driven at a reference speed selected by a microprocessor 10. The processor 10 executes focus detecting operation on the basis of CCD integrating information corresponding to the luminance of an object to obtain a defocused distance D1 at time t1. Then, the processor 10 changes the speed of the lens 2 on the basis of a distance D0 obtained immediately before starting zooming and the obtained speed is held up to time t2. At time t2, information D2 is obtained, the speed of the lens 2 is selected on the basis of D2-D1, and thereafter the driving speed is similarly updated every approximately fixed time. In said constitution, focusing can be always maintained also in zooming without using a coupling material such as a cam ring, the correction lens can be driven at an approximately ideal speed on the basis of distance information obtained every fixed period and focusing accuracy in zooming can be improved.

Title: Method and device for blowing powder to molten metal
Inventor: AIZAWA KANJI
IPC: F27D3/18
Filed: 1989-02-01
Abstract: PURPOSE:To increase the rate of blowing powder by providing a mechanism for separating and discharging a part of a carrier gas in the intermediate part of a transporting pipeline at the time of suspending and transporting the powder by the carrier gas into the transporting pipeline via a lance and blowing the same to a molten metal via a lance thereto. CONSTITUTION:The refining agent powder 10 is suspended and transported by using the carrier gas 12 into the transporting pipeline 14 and is blown to the molten metal via a lance 20. The flow velocity of the carrier gas 12 increases in the section reducing part 32 of the transporting pipeline 14, by which the powder 10 is accelerated and increased in inertia. The powder 10, therefore, progresses the central part and enters the lance 20 without changing the pass orbit even if the powder enters the next section rapidly expanding part 34. On the other hand, the flow velocity decreases sharply to generate vortexes when the carrier gas 12 enters the section expanding part 34. This carrier gas flows into the section expanding part 34 along the inside walls and is partly separated from the powder 10. The separated gas enters the inside of plural radially provided carrier gas discharging flow passages 36 and is discharged from the open end of an outside cylinder 38 via a discharging flow passage 40. The blowing speed of the refining agent powder 10 is increased in this way and the productivity is improved.

Abstract: PURPOSE:To accurately detect a dial pulse under a telephone call by obtaining a position, at which the correlation between a step response and an input signal is large, as the one for the make/break of the dial pulse. CONSTITUTION:An input signal X is analyzed at an analyzing part 31, a coefficient A of a synthesizing filter 2 is obtained, a step response R is obtained at a step response part 32, and a cross-correlation p phixr between the input signal X and the step response R is obtained at a cross-correlation part 33. A step searching part 34 places a first step at the position where the absolute value of the cross-correlation is the maximum, and after that, the step searching part 34 successively obtains the step at the position where the absolute value of the cross-correlation is the maximum except previously determined ranges before and after the position where the step is placed as long as the value of the step is equal to or larger than a value determined according to the value of the first step. Thereafter, the position where the step is placed is made into the position for the make/break of the dial pulse. Thus, a dial pulse signal under the telephone call can be surely detected.

Title: Measuring method of film thickness of electrophotographic photoreceptor and its production
Inventor: MORI NOBUYOSHI
IPC: G03G5/00
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To easily and nondestructively measure a film thickness with high accuracy and to obtain a photoreceptor of high quality having the optimized film thickness without damaging the surface by using a laser scanning measuring device to measure the film thickness. SOLUTION: The film thickness of a coating film is measured with a laser scanning measuring device, and the coating speed is manually or automatically controlled from the data of film thickness. The collimated laser beams 6 emitted from a light-emitting part 1 cross the photoreceptor 5 at a specified scanning speed. The collimated laser beams 6 are partially cut by the photoreceptor 5, which generates charges in the output voltage in a light accepting part 2. The controlling part 3 controls the scanning speed of the collimated laser beams 6 by clock pulses in a controlling part 3 and the pulses in the period when the laser beams 6 are cut are measured. The film thickness is determined by the difference of pulses when the beams are cut by the base coating film and the coating film 7 and when the beams are cut only by the base coating film.  The data of film thickness 7 obtd. is sent to the controlling device 4 as a feedback to control the coating speed.
