Title: Dot matrix light emitting display body and its manufacture
Inventor: TAKECHI SHOJI
IPC: G09F9/30
Filed: 1987-12-26
Abstract: PURPOSE:To clearly visualize the display even when it is light, and also, to improve the visibility at night by condensing a radiant ray emitted from a light emitting display part by a convex lens function of a spherical body. CONSTITUTION:In a light emitting display part 2, a spherical body 15 having light transmissivity is placed in an opening part of a through-hole part 5 formed on a mask plate 4. In this regard, as for the spherical body 15, it is both allowed to fix it by joining it with a resin layer 8 and to fix it by joining it with the mask plate 4. Accordingly, since the spherical body 15 of the light emitting display part 2 has a convex lens function, a radiant ray emitted from a light emitting chip 6 passes through the resin layers 7, 8, and thereafter, condensed in parallel, for instance, as an arrow A or to the center of the spherical body 15 by the spherical body 15. In such a way, the radiant ray from the light emitting display part 2 has sharp directivity, and even when it is alight as daytime, the radiant ray is visualized clearly from a distance. Also, when it is dark as night, etc., an intense light beam is radiated.

Title: Production of microlens array
Inventor: TSUJIKAWA SUSUMU
IPC: G02F1/1335
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To produce a microlens array with plural lenses arranged in a close- packed structure in an easy process with high accuracy. SOLUTION: A chromium protective film is formed on the surface of a glass substrate 1, and circular openings 2 are patterned to form a opening mask 3. Then the substrate is subjected to wet etching using a mixture soln. essentially comprising hydrofluoric acid. Recesses 4 are gradually formed by etching, and recesses adjacent to each other begin to be in contact with each other. In this point, the protective film of the opening mask 3 remains. Further, as the etching process is continued and when recesses 4 at the orthogonal positions are in contact with each other, the protective film on the opening mask 3 is almost completely removed. Thereby, a non-lens part produced by the residual protective film is not produced in this process. Therefore, the microlens array having high an opening rate can be easily produced.

Filed: 1994-12-14
Abstract: PURPOSE: To make it possible to detect the limit running distance of an automatic running machine in a pipe line by computing the average speed of the automatic running machine in the pipeline in correspondence with the moving amount of a control cable. CONSTITUTION: An automatic running machine 20 in a pipe line intermittently advances by alternately pressing and engaging front and rear engaging parts 1 and 2 in an inchworm pattern. A length measuring instrument 13 sends out the signal corresponding to the moving amount of a control cable 8. When the average running speed V for four expansion operating cycles is to be detected at this time, the sending length L of the cable 8 for the nearest four cycles is detected 14 at the final point of the four cycles. The required time (t) for the same expansion operation is detected, and the speed V=L/t is computed 16. Then, at the time point where one cycle has advanced, the speed V is computed by the same way. This procedure is repeated, and the value is displayed 17.  At this time, when the running machine 20 travels forward and approaches the limit running distance, the speed is lowered by the resistance for dragging the long cable 8. Therefore, the approach of the running machine 20 to the limit running distance can be detected by detecting the speed V.
