Abstract: PROBLEM TO BE SOLVED: To easily arrange the axis in the axisymetric orientation in a desired position and to obtain a liquid crystal display element having a stable wide visibility display mode by forming a recess corresponding to the area having a low conductivity in each color layer. SOLUTION: A conductive layer such as an ITO film or NESA film is formed all over a transparent substrate 1 such as a glass substrate and then patterned into conductive layers (transparent electrodes) 2 of a desired shape insulated from each other by photolithographic method or the like. Then a region having low conductivity, namely, a through hole 3 is formed in the conductive layer 2 for electrodeposition. This hole is preferably formed, for example, to have a square, circular or oval plan view. Then a black matrix (light-shielding layer) 4 is formed and color layers (R, G, B) are formed by electrodeposition.  In the electrodeposition process, the substrate 1 having the light-shielding layer 4 formed like a window frame and the lower conductive layer 2 exposed like a window is used as one electrode, and this substrate and a counter electrode are both dipped in an electrodeposition liquid to perform electrodeposition.

Title: Infrared ray detector
Inventor: KUSUKI SHIGERU
IPC: G01J5/34
Filed: 1978-06-12
Abstract: PURPOSE:To enable accurate infrared ray quantity to be detected and achieve  miniaturization and simplification by applying the bias voltage corresponding to the accumulated charge quantity other than quantity of received light in the current detecting circuit in which an infrared ray detecting element and a switch element are series-connected. CONSTITUTION:A bias voltage VT is applied to the inside of the current detecting circuit in which an infrared ray detecting element S and switch element SW are series-connected. VT is expressed by VT = QY/C0. Here, QT, C0 are the charge quantity and capacity value of the element S, respectively. Then, the increment DELTAQ by the energy of received light flows through a resistance R0. This current is let to be DELTAi. Hence, the composite value of the voltage drop component of the resistance R0 and the bias voltage VT is voltage-amplified and therefore the voltage in (a) in the figure becomes VT + DELTAiR0. If the input voltage of an amplifier 1 is e1, the output voltage V0 in (b) in the figure is V0 = R2/R1 (e1 - VT) = R2/R1 (DELTAiR0) = R2.R0/R1 X DELTAi, thus only the charge increment corresponding to the energy of received light is obtainable. Here, R1, R2 are resistances.

Title: Method for conveying flat plate by fluid while being suspended out of touch with flat section
Inventor: KUMA TOSHIMI
IPC: B65H5/22
Filed: 1985-04-05
Abstract: PURPOSE:To enable a flat plate to be suspended and conveyed while it is near a flat section but is out of touch with the flat section by configurating a device in such a way that the flat section is provided in a line approximately perpendicular to fluid flow at the tip end of an opening of a discharge pipe allowing fluid to flow out of the discharge pipe. CONSTITUTION:A flat section 11 is provided in a line approximately perpendicular to fluid flow around a discharge port 5 of fluid, and a flat plate 8 is placed underneath the flat section 11. In this case, if velocity of fluid 7 in a discharge pipe 3 remains constant, fluid velocity within a gap (h) between the lower surface of the flat section 11 and the flat plate 8 is accelerated allowing static pressure within the gap (h) to be dropped as the gap (h) becomes smaller. When static pressure becomes lower than atmospheric pressure, the product of negative pressure and the area of the flat section can be made equal to the weight of the flat plate. Resultantly, only the discharge pipe 3 enables the flat plate 8 to be suspended in an atmosphere while the plate is out of touch with the flat section.
