Title: Color filter, manufacture thereof, and liquid crystal element
Inventor: IWATA KENITSU
IPC: G02B5/20
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent ink color mixture between the adjacent opening parts and to effectively store ink in each opening part for forming a uniform colored part so as to prevent a defect or unevenness by increasing the surface energy on the opening part side face in a light shield layer. SOLUTION: Using a black resin composition, a light shield layer 2 having an opening part is formed on a transparent base board 1. Photocatalytic particles are added to the light shielding layer 2. Using a diffusing plate 3, an UV ray is radiated from the back face of the base board 1 under an ozone atmosphere. When the photocatalytic particles in the light shielding layer 2 are optically excited, the side face of the light shield layer 2 absorbs water molecules in the air so as to be provided with a hydrophilic characteristic. In this way, the surface energy of the upper face in the light shield layer 2 exceeds that of the side face. In this case, a contact angle of the light shield layer 2 with water is 60 deg. or more on the upper face, while it is approximately 20-30 deg. on the side face.  To the opening part in the light shield layer 2, red ink, green ink, or blue ink 4 is applied and hardened so as to form a colored part 5, and if necessary, a protective layer 6 is formed.

Title: Method and apparatus for diagnosing insufficient closure of pressure regulator
Inventor: OKUMA HIDEAKI
IPC: G01M99/00
Filed: 1993-12-02
Abstract: PURPOSE:To realize highly accurate detection and measurement by applying the theory of accumulator to a predetermined position of a gas piping system, e.g. an LPG gas piping system. CONSTITUTION:A bellows 7 slides or moves up and down telescopically along the inner wall of a tubular vessel 6, for example. In this regard, the inner space of the bellows 7 is communicated with a gas piping 1 and a nonleaking action switch 8 is actuated by sensing the upper face position of the bellows 7. A switch operating upon insufficient closure 10 also senses the upper face position of the bellows 7 thus detecting abnormal pressure at the time of insufficient closure of a pressure regulator 2. Flexible pieces for sensing the upper face position of the bellows 7 mechanically are employed as the detection pieces 9, 11 of the switches 8, 10.

Title: Thermal desorption collecting tube
Inventor: NAGOSHI KEIKO
IPC: G01N30/08
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To perform the analysis of a low boiling point substance to a high boiling point substance at one time by an easy and highly sensitive thermal desorption method by comprising three or more filler layers, and filling glass beads in the first layer and a graphite carbon black adsorbent in the second and following layers. SOLUTION: The average grain size of the glass beads which effectively adsorb a high boiling point substance is preferably set to 60-80 meshes since the desorption of the high boiling point substance is difficult in the introduction to a gas chromatograph when it is too small, and the efficiency of adsorption of the high boiling point substance from the atmosphere is deteriorated when it is too large. The specific surface area of the graphite carbon black adsorbent is preferably set to 5-200 m2/g since the thermal desorption rate after adsorption of the high boiling point substance is deteriorated to significantly reduce the recovering ratio when it is too large. The filling quantity of each adsorbent is properly set so that the thickness of each filling layer is within the range of the first layer : the second layer : the third layer = (1:2:1)-(1:3:2)when three layers are used.

Filed: 1990-11-30
Abstract: PURPOSE:To obtain desired optical characteristics by making the interval between first and third recording layers an integral multiple of the effective wavelength so that the degree of freedom of changes in reproducing light quantity is enhanced for multi-valued recording. CONSTITUTION:On a transparent substrate 1, there are successively formed a first recording layer 2, first transparent layer 3, second recording layer 4, second transparent layer 5, and third recording layer 6. The layer 2 has low photosensitivity than the layer and higher than the layer 5. The layers 2, 4, 6 consist of Al, Te, Au thin films, respectively, for pit-type recording layers. The layer 3 and 5 are ZnS thin films, and these films are formed in a manner that the interval between the layer 2 and the layer 6 is mlambda/2n, wherein m is a natural number, lambda is the wavelength of the light source, and n is the refractive index of the transparent layer. By irradiating or not irradiating the recording layer light from the substrate side 1 to the recording medium, four-value states A-D are obtd. for a molten or not molten state of each recording layer. Therefore, reproducing light a-d is obtd. corresponding to these states. Phases of the reflected light coincide well to make an intense beam and to give rather large reproducing light quantity.
