Title: Editing system for terminal retrieving data
Inventor: HIUGA YOSHIHARU
IPC: G06Q40/00
Filed: 1985-08-20
Abstract: PURPOSE:To attain the effective application of an application memory by using the memory of a remote supervisory unit as a terminal retrieving editing buffer when the supervisory unit retrieves the terminal state. CONSTITUTION:When a command is delivered to a terminal 100 from a remote supervisory unit 200 for editing and transfer of data, the terminal 100 sends each data on its state directly to the unit 200 without editing them on an application memory 180. The unit 200 stores those received data in a memory 270 and uses a data area 272 as an editing buffer to edit the terminal retrieving data. As a result, a program area 181 in the memory 180 receives no effect at all from the editing process of the data to be retrieved. This ensures the effective use of the memory 180.

Abstract: PURPOSE:To attain flatness without generating a gap between a coil and a recessed inner wall, by forming a recessed part on an insulating layer, a conductor layer at the bottom only of the recess and the coil in the recess by the plating method. CONSTITUTION:A polyimide system resin PIQ layer 32 (4mm. film thickness) is formed on a substrate 31, an Mo layer 33 (0.3mum) is deposited thereon and patterned by the photo etching method. A PIQ layer 32 is processed for the oxygen sputter etching by using the Mo layer 33 as a mask. Then, a Pt 34 (0.3mum) is vapor-deposited vertically to the substrate 31. A voltage is applied to a Pt layer 34 in 1% sulfamine acid water solution and only the Mo layer 33 is removed by electrolytic etching. Then, the coil 35 is formed in the recess by the electrolytic plating method by using the Pt layer 34' as the electrode. A PIQ layer 32' is coated on the upper surface to make the upper surface flat. Thus, the flat processing is attained easily because no gap is produced between the coil 35 and the inner wall of the recess.

Abstract: PURPOSE:To suppress the frequency fluctuation of an oscillator due to temperature change by combining two kinds of metallic members having different thermal expansion coefficient and utilizing the difference in length due to expansion. CONSTITUTION:The thermal expansion coefficient for a screw 3 and a metallic piece 7 is different from each other, the thermal expansion coefficients are taken as (b), (a), the distance is taken as (l) and the length of the screw 3 is taken as l1, and the temperature range is DELTAl of the distance 5 due to tempera ture change DELTAT is expressed as DELTAll=DELTAT.[al-l1(b-a)]. The size has a relation with an oscillator frequency and when the range in DELTAl changes, the temperature fluctuation width of the oscillated frequency is changed. When b>a in the relation with DELTAl, the value DELTAl changes when the (l) is changed and the polarity of the DELTAl is changed at a certain (l). Since the (l) must be larger than 0, when a more negative is required, the two metals having a large thermal expansion coefficient difference is used.
