Title: Apparatus for controlling compliance steerage
Inventor: SHIBAHASHI KOUJI
IPC: B60G9/00
Filed: 1980-12-11
Abstract: PURPOSE: To control compliance steerage by increasing or decreasing deflection of an elastic body interposed in a car body portion on which a suspension system and steering gear are mounted with hydraulic pressure produced by steerage in the power steering gear.  
     CONSTITUTION: Hydraulic pressure in the left side oil chamber e of a power cylinder 6 in a power steering gear is raised by turning left a handle 9 to lower hydraulic pressure in the right side oil chamber f. Thus, hydraulic pressure in hydraulic pressure cylinder units B, D interconnected through the oil chamber e and a hydraulic pressure pump 24 is raised and that in hydraulic pressure cylinder units C, A is lowered. As a result, insulator rubber is flexed to turn rear wheels 13 left. Namely when operative force caused by hydraulic pressure is larger than side force F acting on the rear wheels 13, the rear wheel 13 is turned left, and when the former is lower than the latter, compliance steerage produced originally is reduced

Filed: 1983-09-20
Abstract: PURPOSE:To improve the covering property of metal for wiring the second layer and to prevent the disconnection of the second layer wirings by burying a gap between the first wiring layer and the interlayer insulating film with a flattening agent. CONSTITUTION:An interlayer insulating film 48 is formed on wirings layer 42, 44 and 46 on a primary insulating film 40. Ultrafine grooves and recesses in the hole 48 and the film 48 are buried by a flattening agent layer 50. Then, the layer 50 is etched until the upper surfaces of the layers 42, 44 are exposed. Then, the first and second metal layers are sequentially covered in a laminated state on the overall surface on the substrate to form the second wiring layers 52, 54. The second layer is patterned by a photolithographic technique using anisotropic dry etching to form upper metal layers 52B, 54B for the second layer wirings, and with the layers as masks the first layer is then selectively etched to obtain lower metal layers 52A, 54A for the second layer wirings.

Title: Method for manufacturing monomolecular built-up film
Inventor: MINAMI KATSUTOSHI
IPC: B05D1/20
Filed: 1992-07-02
Abstract: PURPOSE:To make easy the manufacture of a monomolecular built-up film of ester phosphate which does not allow itself to peel off a substrate easily due to its high adhesive properties by building up a monomolecular film of ester phosphate on the substrate where an aluminum oxide layer is formed. CONSTITUTION:This method for manufacturing a monomolecular built-up film is to scoop off and transfer a monomolecular film floating on a water surface to the surface of a solid substrate. That is, a monomolecular film of ester phosphate builts up on a substrate where an aluminum oxide layer is formed using vacuum evaporation or sputtering technique. If this method is used, the surface of the substrate sticks to the monomolecular film of ester phosphate tightly, so that the first layer does not peel off, and therefore, the built-up film can be formed continuously. The ester phosphate used is such as dioleylphosphate or distearylphosphate having a long chain hydrocarbon group.
