Title: Memory read circuit
Inventor: OOTSUKI MITSUHIRO
IPC: G09G5/32
Filed: 1983-02-17
Abstract: PURPOSE:To obtain a proper picture when plural pictures are displayed on a screen by making the phase of a read data of a memory circuit having different constituting bit number of one address coincident with each other. CONSTITUTION:The address of a memory circuit 2 of one address/one bit constitution is designated sequentially by Q output pulses (Q1-Q4) of a display counter circuit 1, and a data of 1-bit constitution whose address is designated from a D0 output of the memory 2 is read one after another. The address of a memory circuit 3 of one address/8-bit constitution is designated by a Q4 output pulse of the display counter circuit 1 and a data of 8-bit constitution is read all together from D0-D7 outputs. Since the read time of the memory circuit 3 is delayed from a readout time of the memory circuit 2, the data output by a shift register circuit 6 is delayed. Thus, the data output of a shift register circuit 5 is attained from a QD output terminal, the delay time is used in common so as to make the phase of data outputs identical to each other.

Title: Piezoelectric laminated electrical element and its manufacture
Inventor: ARAN JIYON MAIKERUZU
IPC: H01L41/257
Filed: 1989-02-03
Abstract: PURPOSE: To enable polarization of a piezoelectric material after forming a laminate, by establishing conditions for generating a polar potential on the boundary between a piezoelectric material layer and a base material layer of a piezoelectric laminate so as to lower a substantial portion of a polar voltage crossing the piezoelectric layer, and applying the polar voltage for a time longer than a predetermined time under polarity conditions of the material to which the voltage is applied. CONSTITUTION: In one form, an insulating sheet 14 is made of ceramic and typically has a resistivity approximately two orders of magnitude lower than that of PZT forming a piezoelectric layer 12. This resistivity characteristic may be achieved by appropriately doping the insulating sheet 14. A laminate 10 is then held at a preferred polarization temperature, and a polar field is applied to electrode 18, 19. When the temperature is 100 deg.C, for example, the time constant for raising the field to be parallel by leakage of electric charges through the sheet 14 is approximately 1/100×0.72hrs=20 seconds on the assumption that the time constant of the laminate is controlled by the predominant dielectric constant of the PZT layer 12 and the predominant constant of the doped insulating sheet 14.  The field crossing the PZT layer 12 is controlled by the rise time of resistance (or conductance) rather than by the ratio of dielectric constant of the PZT layer 12 and the sheet 14.
