Title: Time division multiplex optical communication system
Inventor: SHIO YASUSHI
IPC: H04J3/06
Filed: 1991-11-13
Abstract: PURPOSE:To simplify the circuit and to make a transmission path fully optical by using one of an optical signal with a different wavelength for transmission of a data string and using the other for a frame synchronizing signal, using a reception section to delay the latter so as to extract data from the data string. CONSTITUTION:One of optical signals of two different wavelengths is used for transmission of a data string and the other is used for a frame synchronizing signal representing a head of the data string and they are sent from a transmission section. The reception section consists of an optical demultiplexer 11 demultiplexing two sent lights with two wavelengths, a delay circuit 12 and a switch circuit 13, a frame synchronizing signal is delayed for a prescribed time by the delay circuit 12 to read an object data bit and the delayed synchronizing signal is used for a switching signal of the switch circuit 13. When the switching signal is inputted to the switch circuit 13, the data bit is read from the data string and outputted. Thus, a clock recovery section and a frame synchronizing signal recovery section are not required. Furthermore, the transmission path is easily made fully optical by employing optical switches entirely.

Patent JP-H06117900-A (JP)
Title: Flowmeter
Inventor: OSADA TASUKU
IPC: G01K11/00
Filed: 1992-10-07
Abstract: PURPOSE:To measure the flow rate of a fluid flowing through a flow passage with a single-tube structure which does not receive any resistance from the fluid by only connecting a shape memory polymer tube to the conduit by utilizing such a property of the polymer material that the dielectric constant of the material changed depending upon the temperature. CONSTITUTION:The capacitance of a detecting section 6 is constituted by putting a tube having a 6-mm outside diameter and 4-mm inside diameter and made of a urethane-based shape memory polymer 1 between two semicircular metallic electrodes 2 facing each other. On the upstream side 3 of the section 6, a constant-voltage and constant-current circuit 5 supplies electric power so as to maintain the temperature of a heating section 4 at a fixed level higher than the ambient temperature. Since the heating section 4 heats a fluid, the temperature of the polymer 1 changes due to the heat transfer by the flow rate of the fluid and, as a result, the dielectric constant of the polymer 1 changes, resulting in a capacitance change of the section 6. The capacitance is converted into an electric signal through a capacitor bridge circuit 7, detection circuit 8, and amplifier circuit 9. Therefore, by only connecting the shape memory polymer tube to the flow rate measuring position of a conduit, the flow rate of the fluid flowing through the conduit can be measured with the single-tube structure which does not receive any resistance from the fluid.
