Title: Dpcm encoding method
Inventor: KATO SHIRO
IPC: H04N19/50
Filed: 1989-11-08
Abstract: PURPOSE:To quickly attenuate the effect of a code error without deteriorating an encoding efficiency by receiving a picture signal and making an encoding direction for a picture element used for prediction and an encoding direction in a picture element to be encoded opposite to each other mutually. CONSTITUTION:A scanning converter 203 writes a video signal from a terminal 201 to two buffer memories FIFO 211, FILO 212 alternately in the unit of lines via a switch 210 and reads the signal alternately in the unit of lines via a switch 213. Since the FIFO 211 reads a signal in the order of input and the FILO 212 reads the signal in the reverse order to the input, a video signal from the terminal 201 is an inverted video signal whose scanning direction is inverted for each line by a scanning conversion circuit 203. A delay circuit 217 in a prediction device 216 outputs one preceding picture element to a picture element to be coded at all times and outputs one succeeding picture element to a picture element to be coded at all times.

Title: Optical pathologic inspection apparatus
Inventor: FURUSAWA AKIRA
IPC: G01N33/483
Filed: 1992-10-28
Abstract: PURPOSE:To detect the change in structure and composition at the molecule level of a sample under inspection by casting a light having the narrow frequency width matching the optical absorbing band of the sample under inspection, generating hole burning in the sample under inspection, and detecting the optical characteristics of the sample. CONSTITUTION:A sample under inspection 21 is dyed with rhodamine 640. The sample 21 is set in a sample chamber 20 through an opening door 2Oa. The sample is quickly cooled with liquid helium to about 4.2K. The sample 21 can be quickly cooled under the state, wherein grains of water crystal are not contained, by the quick cooling. Mutual action is performed with the molecules constituting the sample 21 by dyeing. The state of the molecules constituting the sample 21 is made to reflect on the characteristic amount of holes. When the pathologic part of the sample 21 is detected, at first, the hole forming light is emitted from a light source part 10, and the hole burning is generated in the dyed sample 21. Then, the sample 21 is scanned with the detecting light, whose amount is weakened in order to prevent the formation of the new hole. The transmitted light is detected 40. The depth, the half-value width and the peak wavelength of the hole are analyzed with an analyzing and controlling part 50. Thus the normal state/abnormal state of the sample are judged.
