Title: Dust collector for way tunnel
Inventor: YAJIMA RYOICHI
IPC: B03C3/02
Filed: 1992-09-14
Abstract: PURPOSE:To omit a fan for taking the air in a tunnel into a dust collecting chamber. CONSTITUTION:The upper part of the roadway space 1a of the motor way tunnel 1 is locally closed by a ceiling board 10 to form a sectionally reduced part. An air delivery port 6 of the dust collecting chamber 2 is opened in this part and an air suction port 5 is opened on the upstream side thereof. The wind velocity in the sectionally reduced part of the tunnel increases and the pressure falls below the pressure on the upstream side and, therefore, a pressure difference arises between the air suction port 5 and the air delivery port 6 and the contaminated air in the roadway space 1a is taken naturally into the dust collecting chamber 2 by this pressure difference, by which the need for the fan is eliminated.

Title: Liquid crystal display element
Inventor: NISHIKAWA MITSUTAKA
IPC: G02F1/133
Filed: 1987-10-28
Abstract: PURPOSE:To decrease the variance of an area, to keep rise of a liquid crystal display element constant, and to improve the contrast by determining a metal/ insulating film/metallic element area by a protective film other than that for metal/insulating film/metal. CONSTITUTION:On a glass substrate 10, Ta is brought to spattering, and patterning is executed by dry etching of CF4 (40%)+O2(60%), by which a scanning electrode 1 is formed. This line width has no relation to an MIM element area. By using 1% citric acid, an anodic oxidation is executed, TaOX is provided, and subsequently, it is covered with a protective film 3 of Al2O3 by a spattering method. By covering with a well-known resist and executing the etching by using phosphoric acid, a connecting hole of 5mum+ or -0.5mum is formed. Next, by spattering Cr and executing the etching by using the well-known resist, the upper electrode 4 is formed. Since the area of the MIM element is determined already by the protective film, patterning is executed easily. Thereafter, an ITO picture element electrode 5 is provided as prescribed. According to this constitution, the MIM element area is set to about 20.25-30.25mum<2>, and the variance of the V-I characteristic can suppressed within + or -10%, therefore, a distinct image is obtained.

Title: Thermal-history judgment method and thermal-history display label
Inventor: IKUTA YUJI
IPC: G01K11/20
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To judge a thermal history qualitatively and quantitatively by a method wherein a change in a fluorescence characteristic due to the thermal modification of a fluorescent substance placed under a heating environment together with an object to be heated is measured qualitatively and quantitatively and the relationship between the change amount of a fluorescence characteristic which is measured in advance and the thermal history is found. SOLUTION: A thermal-history display label 40 is composed of a heat-resistant resin film 42 which is composed of a heat-resistant resin to be bonded onto a face to be bonded and in which an adhesive material layer 41 is formed on the rear surface and of an information display pattern 43 which is printed on its surface and which contains a thermal-history labeling agent. As the thermal-history labeling agent, e.g. a compound such as anthracene or the like, its derivative or a substance which is modified to the chemical structure of a support medium is used.  In the thermal-history display label 40, simultaneously with the application of the thermal history due to quick heat conduction from an object to be tested or due to heating from a heat source, the thermal-history labeling agent which is printed on the surface of the heat-resistant resin film 42 generates thermal modification corresponding to the thermal history. When the thermal history is detected, the component of fluorescence generated from the information display pattern 43 is converted into an electric signal so as to correspond as a heat exposure amount.

Title: Liquid crystal display body and its production
Inventor: TAKAMI MANABU
IPC: G02F1/1333
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display body having excellent optical characteristics, heat resistance and impact resistance and high reliability. SOLUTION: The liquid crystal display body consists of a layer of a cholesteric liquid crystal, chiral nematic liquid crystal or mixture liquid crystal 1 of those. The liquid crystal is divided into regions having minimum 5 μm and maximum 100 μm diameters of vernier caliper by a polymer network 4 produced by polymerization of monomers and is in the form of columns having a polygonal cross section or surrounded by closed curved lines so that the incident light is not scattered but sufficiently reflected by the liquid crystal 1. The perpendicular alignment of the helical axis of the liquid crystal 1 to the planes of a pair of ITOs 2a, 2b and substrates 3a, 3b is disturbed a little due to the polymer network 4.  However, most of the incident light from the substrate 3a side is reflected by Bragg reflection to the backward (the substrate 3a side), so that the viewing angle dependence of the device can be reduced compared with a conventional liquid crystal display body having no polymer component. The network 4 formed in a large size forms strong columns (polymer resin walls) to significantly improve the impact resistance.

Title: Image forming device
Inventor: KOYAMA SHIGEO
IPC: G03G15/04
Filed: 1988-10-31
Abstract: PURPOSE:To accurately retain in specified relative positions a processing unit and an optical unit by providing a rotation preventing means which prevents the relative rotation, between the two, with the specified parts of the processing unit and the optical unit as the centers.

Therefore, the optical unit is positioned as specified in the upper direction of the processing unit, and above this optical unit the receiving part, that is a top wall of an opening and closing housing 4 (a part specifying especially the receiving part) is positioned. Thus, the processing unit and the optical unit are directly and accurately retained in the specified relative positions through the position deter mining means and the rotation preventing means.

Abstract: PROBLEM TO BE SOLVED: To provide a fluid pressure detecting circuit allowing fluid pressure, if having a small variation, to be processed in further digital processing with a high resolution by amplifying the variation of fluid pressure, after picked out. SOLUTION: A deviation between an output signal S-A detected by a pressure detecting element 32 and a pre-variation reference signal S-B held by a sample hold circuit 34 is computed by a difference circuit 35.

Fluid pressure itself detected by the pressure detecting element 32 is transformed into a temperature compensated signal Pr1 by a temperature compensation circuit 33 and processed by a digital circuit. Pressure variation, if having a small value, is output as a temperature non-compensated signal Pr2 after amplification and offset and then precisely detected by the digital circuit with a resolution.
