Inventor: YAMAKI MASAAKI
IPC: H04J3/06
Filed: 1990-02-28
Abstract: PURPOSE:To take an MF phase synchronization at every subscriber simultaneously even when the data of different MF phase synchronization is received by providing an MF synchronization pattern detection circuit receiving the output signal of a data storage buffer so as to detect an MF synchronization pattern and an MF phase synchronizing circuit composed of an MF phase selection circuit arranging MF phases for plural subscribers. CONSTITUTION:An output data 3 composed of m-bit is read from a data storage buffer 2 and inputted to an MF phase synchronizing circuit. When a 2nd-bit in a frame is coincident with one of m-set of patterns composed of m-bits subjected to the shift rotation of MF synchronizing pattern, MF bit insert information and MF phase information stored in advance are outputted. The MF phase selection circuit based on the above-mentioned MF phase information selects and outputs one bit in output data 3 of the above-mentioned m-bit till succeeding MF bit insert information is detected. Thus, the MF phase of a subscriber data 101a is synchronized with the internal MF phase.

Filed: 1987-03-06
Abstract: PURPOSE:To clarify a marking part and to reduce the working cost by projecting the thermal energy on the stainless steel surface and controlling the energy to oxidize a projection part at the high temperature and changing it to black. CONSTITUTION:A laser beam 3 condensed by a condenser lens 4 is projected on the surface of stainless steel 1 and a high temperature oxidation reaction of Fe is generated on a thermal energy part 2.

IPC: H05B33/26
Filed: 1989-03-03
Abstract: PURPOSE:To increase the contrast and dielectric strength by disposing black insulation films of an identical thickness between multiple first electrodes and further applying black paint on multiple second electrodes. CONSTITUTION:After disposing multiple first electrodes 2 by patterning transparent electrodes on a first substrate 1, black insulation films 7 of an identical thickness are formed between the electrodes. Over them are laminated a first insulation layer 3, a light emitting layer 4 and a second insulation layer 5. Multiple second electrodes 6 are patterned by depositing electrodes over them. Further, black paint 8 is applied over them. Because the black insulation films 7 are disposed by the number of the first electrodes 2 and by the width of several mum - several hundred mum, height difference due to patterning of transparent electrode ITO is eliminated and no dielectric breakdown occurs at the edge of the ITO. Also contrast is intensified because the periphery of picture element looks black as a result of applying the black paint 8 on the second electrodes.
