Title: Device and method for encoding
Inventor: UEHARA KENJI
IPC: H04N19/423
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To improve a quality of picture in comparison with a conventional one with regard to a digital video signal which frequently moves by converting the number of pixels of a video signal on the basis of the amount of coding of a motion vector and that of coefficient data. SOLUTION: A code generating amount detection circuit 23 calculates an amount of code of a motion vector to be transmitted from a buffer 11 by the frame on the basis of the motion vector detected at a motion vector detection circuit 21. Also, by an integration result detected at the motion vector detection circuit 21, the amount of code of coefficient data to be generated by discrete cosine conversion processing is predicted. A decision circuit 24 for the number of pixels conversion compares an integrated value by the GOP calculated at the code generating amount detection circuit 23 with a specified threshold and outputs the comparison result as the number of pixels switch signal SL.  A conversion circuit 25 for the number of pixels receives picture data from a pre-processing circuit 5 by way of a system delay 26, reduces the number of pixels of these picture data in accordance with a switch signal SL for the number of pixels and outputs them.

Abstract: PURPOSE:To save space and lower costs by decreasing the number of wires and terminals by means of connecting one side of the output terminals of respective sensors in such a manner that they are connected commonly to one side of output terminals of other sensors respectively and also by performing drive control based on a signal taken out from the connected sensors. CONSTITUTION:Hall elements Hu, Hv and Hw are mounted at a motor portion 1 for detecting a rotation angle, and the one side of the output terminal of each Hall element is delta-connected with the one side of the output terminal of other Hall elements respectively for permitting common use. The output terminals P1, P2 and P3 are respectively wired to sensor input terminals P4, P5 and P6 of a control circuit portion 2 through wires L1, L2 and L3.

Title: Method for reducing and melting ash with high temperature hydrogen, method for generating high temperature hydrogen and reducing and melting device
Inventor: NAKAMURA SATOSHI
IPC: C22B5/12
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To treat incineration ash with comparatively low cost by the method of generating less harmful gas by melting the incineration ash while reducing oxides in the incineration ash with the incineration ash being in contact with high temperature hydrogen gas in a condition of oxygen deficiency. SOLUTION: In an incineration ash reaction cylinder 6, directed high temperature hydrogen comes into contact with incineration ash in a condition of oxygen deficiency, and melts and reduces the ash. Molten slag is generated by this melting and discharged from a molten material discharge port 8. When evaporation temperature of metal contained in the incineration ash is considerably high, the metal is discharged from the port 8 in the form of molten metal together with the molten slag. With the melting and reduction, metal of comparatively low evaporating temperature is reduced, turned into metal vapor and discharged from a discharge port 9 together with the exhaust gas generated by bringing hydrogen gas in contact with the incineration ash. High temperature reducing reaction occurs in the furnace 6, and therefore even a trace of oxygen is captured by hydrogen and turned into water.  Thus there is no generation of dioxins or the like and components in the exhaust gas are reduced and become lens.
