Title: Dynamic image coder, dynamic image decoder, dynamic image coding method and dynamic image decoding method
Inventor: ISU YOSHIMI
IPC: H04N19/142
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To reduce the production amount of coded data without deteriorating quality of an image in an important area in a visual sense. SOLUTION: An input image signal 1 is given to an area division section 2. An area shape of one preceding frame extracted from an external memory is used for an initial area shape and the input image signal 1 is divided into pluralities of areas. The area division section 2 applies re-division of the area, based on activity or the like in each area, and conducts integral processing so as to reduce the coding cost between one area and its vicinity area. Area shape information 3 or the like decided by the area division section 2 is coded at a coding section 7 and converted into a bit stream 11. The coding section 7 provides a locally decoded image 8 and writes it to an external memory 9. The locally decoded image 8 is used for a reference image 10 for area division processing and coding processing.  The area shape information 3 is written in the external memory 9 and used for area division processing.

Title: Magnetic disk device
Inventor: SATOU CHIYOUSAKU
IPC: G11B19/04
Filed: 1981-12-30
Abstract: PURPOSE:To obtain a magnetic disk device with which an error due to the mixture of a foreign matter can be eliminated even though the disk device is turning, by providing a cleaning device to get rid of foreign matters attached to a magnetic head. CONSTITUTION:The hardness is controlled for the material of a file-shaped member in order to avoid shaving a metallic part of a magnetic head. When an error detecting circuit EDT detects an error during the reading of a disk pack DKP, only the head can be cleaned by a software process. Therefore the disk continues its revolution to avoid the complete stoppage of the operation of the disk device. That is, a signal is fed to a head cleaning indicating signal transmitting circuit CLC when the circuit EDT detects an error. Then a cleaning indicating signal is delivered and received by a receiving circuit CLR. Thus an operation control part CNT2 is indicated to separate a head mechanism part HDB from the pack DKP and to set the head HD at the position of a cleaning device HCL.

Title: Method and apparatus for measuring saturation current of field effect transistor
Inventor: TATEMATSU MIKIO
IPC: G01R31/26
Filed: 1985-09-27
Abstract: PURPOSE:To enable saturation current to be measured with a high precision, by connecting gate and source electrodes by means of a connecting body. CONSTITUTION:A source electrode S is connected t a gate electrode G through a resistance R instead of short-circuiting them. A predetermined voltage VD is applied between the source electrode and a drain electrode, and a current value ID is measured. In this case, a voltage drop ID.RS occurs at a contact resistance RS. In case of measuring IDSS, since no DC current flows through the gate electrode, the source and drain electrodes are maintained at an equivalent potential. Accordingly, the current ID can be measured with a high precision as a measurement of IDSS from which the contact resistance has been eliminated.
