Filed: 1993-03-01
Abstract: PURPOSE:To provide a driver for brushless motor in which normal driving state of motor can be sustained even upon occurrence of step-out at the time of starting the motor or abrupt variation of load. CONSTITUTION:The driver for brushless motor comprises a conduction switching circuit 10 equipped with a step-out control section 12 for controlling the driving of transistors 4-9 based on an output from a detector 11 for detecting counter electromotive force induced in driving coils 1-3.

Title: Image data converting method for digital printer
Inventor: TERASHITA TAKAAKI
IPC: G06T5/00
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a high-quality digital image based on a face area extracted from a film image. SOLUTION: R, G and B signals are converted into luminance signals and chrominance signals by a converting means 11. The face area is extracted by a face area extraction processing means 12. A face area size is found by a face size estimating means 13. Based on a face area size signal, an edge emphasizing means 14 performs edge emphasis processing to the luminance signals. Concerning this edge emphasis processing, the more the face size is reduced, the more the degree of edge emphasis is improved. A gradation correcting means 20 and a color tone correcting means 22 perform correction for eliminating the deviation of input and output systems. The luminance signals and chrominance signals are converted into the R, G and B signals by a converting means 21.  Based on these converted image data, an image recording controlled variable converting means 23 converts an image into a recording controlled variable and afterwards, the image is recorded by an image recording means 24. Since the image is processed corresponding to the face area size, the suitable method of picture quality improvement corresponding to scenes can be adopted and picture quality can be improved.

Abstract: PURPOSE: To ensure a high-accuracy jitter correction at the reproduction time by drawing out the burst-type pilot signal from the SECAM composite color video signal to be recorded and then inserting the pilot signal to the proper place of the video signal.  
     CONSTITUTION: Composite color video signal (a) sent from terminal 10 and to be recorded enters circuit 12 to produce nonmodulated subcarrier DR line sampling gate pulse P 1  and burst gate sampling switcher pulse P 2  respectively. Pulse P 1  is applied to gate 26, and burst-type 282fH is produced with every two lines of the SECAM signal to obtain signal (b). Signal (b) is then double-multiplied through counter 30 to be changed into signal (c), and continuous wave (d) is given via the start-stop oscillator comprising phase detector 32 and voltage control oscillator 34. Wave (d) is divided 38 into 1/2 to obtain signal (e). Signal (e) gives strobing to the continuous wave with the proper timing at burst gate switcher 42 and via pulse P 2  to deliver signal (f). Signal (f) is mixed with signal (a) at mixer 46 to deliver signal (g) containing burst (f) at each horizontal sychronous part. Thus, the jitter can be corrected.

Title: Method for discharging residual slag
Inventor: FUJITA TAKASHI
IPC: C21C1/02
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To efficiently discharge residual slag without allowing the solidification and adhesion thereof by discharging the slag remaining in a molten iron receiving vessel at a specific temp. after delivering molten iron from this vessel. SOLUTION: The residual slag in the molten iron receiving vessel is discharged at >=1000 deg.C slag temp. after delivery of the molten iron. If the assurance of >=1000 deg.C slag temp. is difficult, the residual slag is discharged at >=900 deg.C by heat insulating or heating the slag. The heat insulation of the residual slag is executed by adding heat insulating materials, such as materials of paper making sludge or rice hulls, to the slag or coating the surface with these materials to suppress heat radiation. The heating is preferably executed by adding exothermic agents, such as carbon and metals, to the residual slag to effect heat generation by chemical reaction.
