Title: Limit sufficing solution sequential calculation method for linear limit condition
Inventor: AOKI TAKESHI
IPC: G06F19/00
Filed: 1990-10-17
Abstract: PURPOSE:To calculate a new limit sufficing solution with high efficiency when the limit conditions are newly added by converting the standard linear limit conditions into the conditions expressed in a base form with use of a precedently obtained limit sufficing solution. CONSTITUTION:The input linear inequality conditions are converted into the standard linear limit conditions by a converter part 12. Then, 8 converter part 14 converts the standard linear limit conditions into the conditions expressed in a base form expression with use of a precedently obtained limit sufficing solution. In addition, a limit sufficing solution generating part 16 solves an artificial problem in a simple method. Thus, a limit sufficing solution is produced from the conditions expressed in a base form and outputted to an output part 18. As a result, a new limit sufficing solution is obtained just with a partial change of a solution when the new conditions are added after the limit sufficing solution of a simultaneous inequality is obtained. Thus, the limit sufficing solution can be obtained at a high speed.

Title: Formation of connecting hole
Inventor: NAGAYAMA TETSUJI
IPC: H01L21/28
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To improve the insulation breakdown strength between an n<+> type polysilicon film and a plug embedded in a contact hole (CH) in the self- alignment contact process where the CH is made in a laminated film formed of SiOx film, n<+> type polysilicon film and SiOx film. SOLUTION: While a laminated film is dry-etched, a gap is generated in the boundary between a second interlayer insulation film 4 and an n<+> type polysilicon film 3 because of a side-wall protection film made of carbon-based polymer. Therefore, the side wall on the side-wall surface of a contact hole is completed through two steps, thereby preventing lowering of coverage property of the insulation film due to the generated gap. That is, the gap is first absorbed by a first side wall 10SW made of SiOx, and next a second side wall 11SW made of SiOx is formed thereon. Thus, the processing section of the film 3 can be covered with an insulation film of appropriate thickness.

IPC: B29C33/76
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To precisely detect the resin filling degree of a cavity in an injection process. SOLUTION: A hole portion 17 for communicating with a cavity 15 is provided in a slide core 19. A slide pin 22 is freely movably inserted in the hole portion 17, and a proximity sensor 18 is provided in a stationary mold 1 for detecting a displacement of the slide pin 22. During condition determining molding, a molten resin is injected into the cavity 15, and the pressure in the cavity 15 increases. When the cavity 15 is filled with a necessary amount of the molten resin, the slide pin 22 immediately moves, and the displacement thereof is detected by the proximity sensor 18, thereby determining completion of the injection. In this process, time from the start of injection of the resin into the cavity 15 to the detection of the slide pin 22 by the proximately sensor 18 is measured.  By repeating the condition determining molding, the time such that non-defective articles will be obtained is selected. In normal injection molding, the slide core 19 is replaced with an ordinary slide core, and the injection process is performed for the selected time.

IPC: F16F9/00
Filed: 1992-09-22
Abstract: PURPOSE:To prolong the service life of a gun cylinder, and reduce the cost by making a cushion effective while narrowing down an air flow rate exhausted from a pressure cylinder by an air cushion means. CONSTITUTION:By a gun pressure cylinder, a thrust required for pressure welding is generated in the tip of an electrode of a piston shaft 3.
