Abstract: PURPOSE:To improve a property for prevention of flasifying by a method wherein a rear face of a transfer sheet is divided by an area of a microcapsule layer of a different coloration, and a developer is incorporated on, in, or under at least one microcapsule layer, which is allowed to develop color by itself. CONSTITUTION:A transfer sheet 2 is composed by providing a microcapsule layer 4 of a color couper A, a microcapsule layer 6 of a color coupler B, and a mixture layer 5 containing a developer 7 by classifying on a rear face of a base material 3. Then, a thermal sensitive transfer sheet for prevention of falsifying is composed by combining it with an acceptive sheet 8 wherein a developer 10 is provided to all surface of a base material 9. When entry is carried out on a surface of the transfer sheet 2 by means of a ball point pen 11 or the like, respective color couplers A, B of the micro-capsule layers 4, 6 are transferred to the acceptive sheet 8, and images 13, 14 of different color tones are formed.

Title: Dc-dc converter
Inventor: KAMIOKA HIDEO
IPC: H02M3/155
Filed: 1987-12-30
Abstract: PURPOSE:To reduce loss and noises by transferring energy to the load side through a choke coil connected in series with an energy transmission line during the conduction of a switching element. CONSTITUTION:A capacitor 10 in capacitance C connected in series with a diode 5 and an inductance 11 are mounted in a DC-DC converter. The time when currents i1 are brought to zero, a period when a switching element 2 is turned OFF, is set on the basis of a time scale by the capacitor 10 and the inductance 11. Consequently, when the element 2 is conducted by a signal from a control circuit 9, energy is transferred from a DC power 1, and load currents i0 are supplied while the capacitor 10 is charged. When an energy transfer cycle is completed, the switching element 2 is turned OFF, thus switching the element 2 under the state in which currents i1 are brought to zero, then reducing loss and noises.

Title: Movement compensation estimation encoder
Inventor: KAMIKURA KAZUTO
IPC: H04N19/593
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a movement compensation estimation encoder which can decide a global movement compensation ON/OFF state without deteriorating the encoding rate by using the motion vectors against an encoding object block and its adjacent block and also the global movement compensation ON/OFF selection information when the overlap movement is compensated. SOLUTION: In an OMC(overlap movement compensation) mode where the movement is compensated in combination of the GMC(global movement compensation) and the OMC, a comparison part 11 selects one of both compensation estimation error signals received from the original image LMC(local movement compensation) parts 7 and 9 that has smaller absolute value sum and sends the selected error signal to a comparator 13. Then the GMC.ON selection information and the GMC.OFF selection information are sent to a switch changeover part 14 when the LMC 7 and 9 are selected respectively. Then the comparator 13 compares the dispersion of signals sent from the part 11 with that of the encoding object image signals sent from a memory 3 to decide the inter- frame or intra-frame processing. Thus the encoding efficiency of moving image signals and the picture quality of reproduced images can be improved.
