Title: Pretilt angle measuring instrument of liquid crystal cell
Inventor: HIGA MASAKATSU
IPC: G02F1/1337
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to exactly measure a pretilt angle of a desired position even if the liquid crystal layer thickness of a liquid crystal cell is nonuniform and the rotating angle thereof is large by disposing a means for shifting an optical path according to the rotation of the liquid crystal cell and means for varying the spot size of incident light into the incident optical path on the liquid crystal cell to be measured. SOLUTION: A light source 2, a polarizer 3, an optical element 4 for varying the measurement area, an optical element 5 for correcting the incident side optical path, an analyzer 7 and a photodetector 8 are arranged in one row. The parallel beams emitted from the light source 2 are polarized by the polarizer 3 and the spot size of the measuring beam of the optical element 4 for maintaining the specified measurement area by rotation of the liquid crystal cell is variably adjusted according to the rotating angle of the liquid crystal cell. These beams are passed through the optical element 5 for correcting the mispositioning of the liquid crystal layer where the light passes and thereafter, the beams are made incident on a measuring sample LC and are passed therethrough, then through the analyzer 7, following which the intensity of the transmitted light is detected by the photodetector 8. The pretilt angle is determined from the angle at which the intensity of the transmitted light is symmetrical.

IPC: H01L21/331
Filed: 1989-10-26
Abstract: PURPOSE:To prevent the change in distributing ratio of a main current and a sense current due to the change in temperature without enlarging the shape, to make a sense voltage correspond to the magnitude of the main current regardless of the change in temperature and to ensure the detection of overcurrent by forming a resistor (RT) having a temperature coefficient where the ratio between the main current and the sense current becomes adequately constant with respect to temperature change with an N<+> diffused region, a part of which is surrounded with a P<+> diffused region formed in an N-type silicon substrate. CONSTITUTION:In an N-type silicon substrate, a transistor part 1, a resistor RT part 2 and a sense resistor RS part 3 are formed. An N<+>U diffused region 5 is formed at the approximately central part of a P<+> diffused region 4. The bottom surface and the side surface of the P<+> diffused region 5 are surrounded with the P<+> diffused region 4. A polysilicon layer 6 is in contact with the upper surface of the N<+>U diffused region 5. One end of the layer 6 is connected to the sense emitter of the transistor part 1 through an aluminum electrode 7. Since the diffused region having the high resistivity formed in the silicon substrate is used in this way, the transistor having the current detecting function which can achieve space saving can be obtained.

Filed: 1992-10-16
Abstract: PURPOSE:To improve reflection/loss characteristics by combining three lines whose length become specified wavelengths by means mutually of a prescribed frequency and mutually compensating reflection occurring on account of susceptance. CONSTITUTION:In an equivalent circuit, a load resistance which an external resistance connected to a second line 9, a third line 11 and a third input/output terminal 7 shows is loaded on a third input/output terminal 7-side in a capacitor Ca connected to a first connection point 2. When first and second field effect transistors 4 and 6 are selected in such a way that an impedance that the capacitor Ca shows as against an impedance which the load shows, the influence of the load can be ignored. In such a case, two capacitors are loaded at the intervals of a 1/4-wavelength. Thus, reflection generated by the capacitors are mutually compensated by a wide frequency, and a satisfactory transmission characteristic can be obtained.
