Title: Measuring method for turbidity and chromaticity
Inventor: TAKAHASHI TAKAO
IPC: G01N21/85
Filed: 1981-05-12
Abstract: PURPOSE:To measure the turbidity and chromaticity of liquid in a vessel such as a reaction vessel, etc., a river, a lake and the sea, etc. in a natural state without sampling it, by using a glass fiber tube and placing only photodetecting part of it in the liquid to be inspected. CONSTITUTION:Light from a light source 1 divided by a beam splitter 4 is passed through a glass fiber tube 7 and is introduced into a photodetecting part 8 immersed in the liquid to be inspected. The light transmitted the part 8 is introduced into a photoelectric conversion element 5' passing through a glass fiber 8' again. The part 8 is constituted by covered glass fibers 7, 7' and right angle prisms 9, 9' held at a constant interval by spacers 10, 10' and the light from the light source is transmitted through the liquid to be inspected part shown as one-dot chain line 14.

Title: Active matrix liquid crystal display device
Inventor: YAZAWA SATORU
IPC: G02F1/1337
Filed: 1985-04-04
Abstract: PURPOSE:To eliminate the occurrence of a display defect such as an afterimage phenomenon characteristic to an active matrix by using such a material that a substrate surface contacting a liquid crystal layer has higher resistance than a liquid crystal bulk layer for a substrate surface. CONSTITUTION:A gate line 8 and a picture element electrode 7 are insulated by an interlayer insulating film 10, an insulating layer 6 prevents a DC compo nent from being applied to the liquid-crystal layer 5 and a slantingly vapor- deposited film 1 is formed thereupon so as to orient liquid crystal. The film 1 is stuck thinly on the substrate surface and does not continue laterally, so the lateral resistance becomes extremely high and the surface is less active than a rubbing surface and adsorbs a conductive material to hold interface leak resistance sufficiently large. Therefore, display defects characteristic to the active matrix such as an irregularity in contrast, an after image phenomenon and crosstalk are eliminated.

Title: Output circuit of micro processor
Inventor: YABUUCHI HIDEKAZU
IPC: G06F15/16
Filed: 1978-06-13
Abstract: PURPOSE: To shorten a pulse duration by making it possible to output positive or negative pulses at one instruction execution by giving a constitution where output data held in the output latch is inverted by an inverter circuit.  
     CONSTITUTION: At a latch output instruction execution time, output latch control signal a applied to control input A of output latch 1 becomes active, and output data is held at output B of latch 1. At this time, since inversion control signal b applied to control input E of inverter circuit 2 is non-active, data at output B is sent to output D through input C of circuit 2 as it is. Meanwhile, at a pulse output instruction execution time, past output data is held at output B continuously while leaving signal a non-active, and signal b becomes active. Then, after output D of circuit 2 is inverted, signal b is made non-active to return output D to the original state, thereby outputting pulses.

Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To enable the dry etching adaptable to microfabrication below specified width, irrespective of the pressure by using a wide antenna as a single- winding high frequency coil for generating a discharge plasma and feeding a more amt. of gas than the vol. of a discharging chamber above a substrate.

A magnetic field generating means for forming an annular magnetic neutral line is composed of a small-diameter disk-like or doughnut- like permanent magnet 3 disposed on the top of the dielectric 2 and annular permanent magnet 4 having a larger inner diameter than the magnet 3. A wide antenna disposed between the two magnets 3, 4 forms a single-winding high frequency coil 5 for generating a discharge plasma. An etching gas to be fed is controlled so that its flow rate is 15(±3)×V sccm where the vol. of a reaction chamber is V lit. Thus a reactive dry etching apparatus adaptable to fine machining below 0.3 μm width can be realized.
