Patent JP-H09329474-A (JP)
Title: Flow meter
Inventor: INADA YUTAKA
IPC: G01F1/00
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a flow meter which can make changing-over of display without impairing the air-tightness of the case nor requiring complicated procedures. SOLUTION: This flow meter is equipped with the first and second photo-electric transducer elements 19, 20, a differential amplifier 21 to generate a differential signal B upon comparing the sensing signals given by these elements 19, 20, and a comparator 23 which emits a display changeover signal A when the signal B has becomes over the first reference value C. The display changeover signal A is issued when a window facing either of the elements 19 and 20 is blocked to cause the difference between the sensing signals from them 19 and 20, i.e., the differential signal B, to become greater than the first reference value C. With this, the air-tightness can be well maintained, compared with a conventional technique which includes a changeover switch penetrating the case.  Compared with another conventional technique which uses a magnet, this does not require setting-off of any particular space for accommodation of components or management of the components, nor require taking them out from the place of accommodation, so that the changeover operation can be conducted without complicated procedures.

Title: Liquid crystal display panel
Inventor: IWAI YOSHIO
IPC: G02F1/139
Filed: 1990-06-25
Abstract: PURPOSE:To decrease the pretilt angle of liquid crystal molecules in bulk and to improve display characteristics in an (electrically controlled birefringence) (ECB) mode by combining a tilted and perpendicularly oriented layer and a perpendicularly oriented layer. CONSTITUTION:The 1st oriented layer 2 in which the liquid crystal molecules attain a tilted perpendicularly oriented state inclined several degrees from the direction perpendicular to a substrate is formed at the substrate boundary of one substrate 1 in contact with the liquid crystal and the 2nd oriented layer in which the liquid crystal molecules attain the perpendicularly oriented state is formed at the substrate boundary of the substrate 1 opposite thereto. The perpendicular orientation inclined several degrees is, therefore, attained in the tilted perpendicularly oriented layer 2 and the perfect perpendicular orientation is attained in the perpendicularly oriented layer 3 and, therefore, the pretile angle of the liquid crystal molecules in bulk attains the value of about 1/2 pretile angle in the tilted perpendicularly oriented layer 2. The double refraction quantity is thereby decreased and the quantity of the transmitted light in a dark state is fairly decreased. The pretile angle of the liquid crystal molecules in bulk is decreased in this way and the display characteristics in the ECB mode are improved.
