Title: Plasma display panel
Inventor: OKAJIMA TETSUJI
IPC: H01J11/34
Filed: 1992-04-23
Abstract: PURPOSE:To reduce a voltage for writing data and increase speed and reliability in writing by expanding the area of a data electrode up to the size of a dis charge cell in the part of the discharge cell and making the area of the data electrode narrower than the width of a barrier plate in the part of the data electrode, which is under the barrier plate. CONSTITUTION:The area of a data electrode 1 is expanded up to the size of a discharge cell 5 in the part thereof which is in opposite to a scanning electrode within the discharge cell 5 to maximize the effective electrode area thereof. However, the width of the electrode 1 is made narrower than that of a barrier plate 4 in the part thereof, which is under the barrier plate 4. Thus, a voltage required for the discharge of data writing is reduced by increasing the effective electrode area of the electrode 1. The easiness of the discharge of data writing is proportional to a difference between a voltage applied to the electrode 1 and the minimum value of a voltage required for the discharge of data writing, and therefore, the lower the minimum value of the voltage required for the discharge of data writing made, the surer the data wiring is made. Thus, the speed and the reliability of data writing are increased by reducing a voltage for data writing.

Abstract: PURPOSE:To prevent a wiring from being partially lost and to prevent a protective film or an upper wiring from being defective due to hillocks, by adhering a resin film of polyimide resin on the upper face of a wiring of Al or an Al alloy such that the resin film has the same pattern as the wiring and by depositing an insulating protective film by plasma CVD so as to cover the surface and the side faces thereof. CONSTITUTION:A resin film 5 formed of polyimide resin is provided on the upper face of a wiring 3 consisting of Al or an Al alloy. An insulating protective film 4 consisting of a P-SiN film or the like is deposited by plasma CVD so as to cover the surface of the resin film 5, the side faces of the wiring 3 and the surface of the insulating film 2. According to this construction, the upper face of the wiring 3 is prevented from being directly contacted with the insulating protective film 4 during the formation of the film 4 by the presence of the regin film 5 interposed therebetween. The tensile force from the insulating protective film 4 is therefore reduced, as a result of which the wiring can be prevented from being partially lost. Further, when the resin film 5 is provided on the upper face of the wiring 3 to cover hillocks 3b thereon, the resin film 5 fills the hillocks to form a flat surface, so that the surface of the insulating protective film 4 also can be flattened.

Title: Dimensionally stabilizing method for wood
Inventor: TAJIMA TOSHIYUKI
IPC: B27K1/00
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent a wood from warping, crooking and cracking, to make it strong in moistureproofing and drying resistance and stabilize the dimensions of a wood so as to realize its fair and long use by a method wherein a synthetic resin paint mixed with a small amount of a water retaining agent is applied onto the surface of a wood. SOLUTION: Almost all the surface of a wood 1 is covered by a synthetic resin paint 3 and a water retaining agent is sporadically present in some part of its surface. As a result, during the water retaining agent is present in a synthetic resin paint layer 2, the water retaining agent 4 serves a waterproofing action by being repeated with actions such as the direct exposure of the surface of the wood to rain and water, the expansion of the water retaining agent 4 on humid days such as rainy days or the like, the return of the water retaining agent to its initial state by drying on fine days by means of weather conditions. Further, when the water retaining agent 4 exfoliates by long term use, no water is hard to enter a small recess formed by the exfoliation.  On the other hand, since the surface of the wood is coated with the synthetic resin paint 3 except small holes, the wood respires through the small holes through the repeating wetting and drying, resulting in realizing the slow drying of the wood and consequently neither warping nor crooking nor cracking develops.

Title: Process controller
Inventor: SHIMAZAKI TERUYUKI
IPC: G05B11/36
Filed: 1988-04-28
Abstract: PURPOSE:To facilitate the control of a process at change of the set value by obtaining the set value of a control point via the addition or subtraction to the present process signal with use of an output level signal and self-supporting the calculated set value as a process set value signal to give this signal to a process control means. CONSTITUTION:The addition or subtraction is performed between the process signal and the set value of a control point obtained at that time point and this calculated value is automatically self-supported as a process set value signal SV by means of the self-supporting signal obtained from the level signal of a level detecting means 5 after the set value of the control point is once obtained from a control point setting means 7. The process control is carried out by the process control signal MV received from a process control means 10 so that the process signal follows the signal SV. As a result, the signal SV itself is automatically changed with the change of the level setting value of the means 5. Thus it is possible to facilitate the control of a process when the set value is changed and to avoid occurrence of the artificial setting mistakes.
