In a semiconductor wafer having a small contact window part, the distance A between the target electrodes is reduced and the flying range B of the aluminum atom is extended in order to reduce the oblique component and to increase the perpendicular component. Because the oblique component S3 is little, a self-shadow phenomenon is not caused.

IPC: G02F1/35
Filed: 1992-09-04
Abstract: PURPOSE:To provide the org. nonlinear optical material having a high nonlinear optical effect by forming a water surface development film by using a specific compd. CONSTITUTION:This org. nonlinear optical material consists of the water surface development film obtd. by developing a soln. contg. the salt of the ruthenium (II) trisbipyridine deriv. expressed by formula (where n is integer of >=12), a film formable polymer and a solvent on a water surface. In the formula, n is >=12 and the upper limit thereof is adequately 20. The aq. soln. becomes large and is, therefore, easily soluble in the water and the soln. is hardly soluble in the solvent if n is <=11. The more particularly preferable n is 14 to 18. Since the ruthenium (III) trisbipyridine deriv. is bivalent cation, the anion forming the salt of the deriv. is a bivalent anion or two pieces of univalent anions. The salt includes a halogen compd., perchlorate, chlorate, etc., and is more particularly preferably the perchlorate (salt with two pieces of ClO4).

Title: Pressure sensor
Inventor: KODAMA SEIKI
IPC: G01L9/00
Filed: 1990-10-02
Abstract: PURPOSE:To obtain a sensor hardly influenced by the ambient temperature change and capable of preventing erroneous detection by absorbing the changing amount of the volume of a pressure transfer liquid generated in accordance with the ambient temperature change by an absorber having a large volume compressibility. CONSTITUTION:An absorber 10 is provided within a pressure transfer chamber 7 to absorb the volume change of a pressure transfer liquid 6 accompanying the temperature change, and is formed of rubber having a low thermal expansion coefficient and a high volume compressibility. In the formula, V0(1+alpha t)(1-beta P) represents the volume of the absorber 10 after the temperature is raised. Therefore, if alpha,beta are set so that the decreasing amount of the volume the absorber 10 after the temperature rise, i.e., V0-V0(1+alpha t)(1-beta P) is equal to the increasing amount V'0r t of the volume of the pressure transfer liquid 6, the pressure in the pressure transfer chamber 7 is stabilized with the increase of  P. In the case where the volume of the pressure transfer liquid 6 is slowly increased in accordance with the temperature rise around the pressure sensor, although the pressure inside the pressure transfer chamber 7 is increased by  P, this increase is within an allowable range of a pressure detecting part 2. Therefore, the increase of the volume of the pressure transfer liquid 6 can be absorbed by the absorber 10.

Title: Substrate for liquid crystal display device, and liquid crystal display device
Inventor: KAJITA JUNJI
IPC: G02B5/20
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To reduce a defect in orientation and a defect in display, and to make display quality excellent by providing a spacer which is fixed in a non- display area, and making the spacer higher at its center part than at its peripheral edge part. SOLUTION: The substrate for the liquid crystal display device has the fixed spacer, which is higher at the top-layer center part than at the top-layer peripheral edge part, in the non-display area. The top-layer center part of the spacer is normally 0.05 to 2μm, preferably, 0.1 to 1μm higher than the top-layer peripheral edge part. The spacer which is higher at the top-layer center part than at the top-layer peripheral edge part comes into surface contact with the substrate that the spacer faces when the substrate is pressed, so wires and an orientation film on the opposite surface are hardly flawed and the display quality seldom decreases owing to a display defect or orientation defect. Further, this spacer makes it smooth to inject liquid into between the spacer and opposite substrate, so that an air bubble is hardly formed.
