Title: Receiver for optical communication
Inventor: SHINOZUKA NORIYUKI
IPC: H04B10/272
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To track the positions of light sources and to realize desired optical communication by specifying a light-receiving element among elements arranged in a matrix form even if light signals are simultaneously made incident on the light-receiving element from the plural light sources. SOLUTION: In a light-receiving element array arranged in the matrix form, a horizontal scanning circuit 4 and a vertical scanning circuit 7 send signals showing the positions of switching MOSFETSW12 and 34 becoming in a on-state to a detection circuit 3 by the element receiving the light signals from the light sources. The detection circuit 3 specifies the position of the photodiode receiving light and informs a decoder 8 of it. The decoder 8 outputs the output signal of the element receiving the light signal to a terminal T by setting one of switching MOSFETS1-S4 to be the on-state based on the signal. Thus, even the light signals from the plural light sources can track the positions of the light sources, mutually read the output signals of the light-receiving elements and can execute optical communication with plural opposite stations.

Title: Assembly of vessel and dispensing-closure
Inventor: KAARU JIEE BOBINJIYAA
IPC: B65D47/28
Filed: 1988-07-14
Abstract: PURPOSE: To make a material being dispensed from a container while the cap of a container stays at a fixed position by letting a plug means engage with an opening of a passage to form a seal against fluids, and forming the passage to allow free flow of the fluid from interior of the container to orifice when a cover means is open at the dispensing position. CONSTITUTION: An escape region 68 extends to the whole periphery of a plug 64 so as to allow it to be inserted smoothly into a dispense orifice 44 in order to make seal against the fluid in the passage 46 more perfect at the position where the closure is closed, namely a non-dispensing position, and further gives pliability to the plug 64. The length of the front wall 53 is determined so that it can completely cover the dispensing orifice 44 when closure is at the closed position. This is convenient for users to operate because the passage 46 opens by merely pushing up the edge portion 54 of the cover 48. The material can then be dispensed from the container 10 by tilting it and squeezing its both elastic sides.
