Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a module for optical communication capable of separating and receiving signals of desired wavelength bands of multiplex optical communication with good accuracy. SOLUTION: This module consists of a light emitting element 1 which generates a transmission signal, a condenser lens 4 which couples the transmission signal light from this light emitting element 1 to an optical transmission path, a light receiving element 2 which receives the reception signal light from this optical transmission path and a beam splitter 3 which respectively inclines the reflection surface of a half mirror 31 and the reflection surface of a WDM filter 32 for reflecting the signal of the desired frequency band and allows the transmission of the frequency bands exclusive thereof and is held by a transparent body 33 apart a specified spacing therefrom. The half mirror 31 of the beam splitter 3 exists in the optical path between the light emitting element 1 and the condenser lens 4.  The beam splitter 3 is so disposed that the reception signal of the desired wavelength band from the optical transmission path is reflected by the half mirror 31, is further reflected by the WDM filter 32 and is made incident on the light receiving element 2.

Title: Diaphgram for redox flow cell
Inventor: YAMAMOTO TAKAHISA
IPC: H01M8/02
Filed: 1986-08-22
Abstract: PURPOSE:To reduce metal ion transmission, increase voltage efficiency and Coulomb efficiency, and improve durability by having a specific chain aliphatic compound and a pyrrole compound polymer coexist on one side of a positive ion exchange membrance. CONSTITUTION:A chain aliphatic compound of carbon number between 6 and 30 and a pyrrole compound polymer are made to coexist on at least one side of a positive ion exchange membrance. This results in a diaphragm with higher Coulomb efficiency in particular and superior durability too, compared with a diaphragm having individually either a chain aliphatic compound of carbon number between 6 and 30 or a pyrrole compound polymer. Besides, transmission of metal irons such as those of chromium and iron can be reduced without causing an increase of membrance resistance, and Coulomb efficiency can be increased in addition, by the reaction of the aliphatic compound, in the range of more than in general, 200Angstrom  on one side of the membrance and less than 1/3 of the membrance thickness.

Title: Method and device for bidirectional data exchange on low and medium voltage power lines
Inventor: GUIDOTTI GIOVANNI
IPC: H04L5/14
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To attain bidrectional exchange of a large quantity of information at a high bit rate by performing the OFDM or OFDMA modulation of data supplied from a central digital or digitized data supply source which uses a power line. SOLUTION: Input data I are inputted to a block C&M which encodes the bits and secures matching between these bits and the arrayed symbols, a block S/P which converts a serially inputted data into a parallel data and a block IFFT which calculates the inverse fast Fourier transform of the parallel data. The output of the block IFFT is added to a guard via the block G&P and converted into the serial output from the parallel one. The parallel output is converted into the analog output from the digital one via a block D/A&F, transmitted through a filter, undergoes the frequency conversion via a block FUC and then sent to a common channel CHN which receives the noise and an interference N&I.  The output of the channel CHN undergoes the second conversion of frequency via a block FDC and is inversely operated to decode the data via a block DEC&DEM after passing through several blocks. Thus, the output data O are obtained.

IPC: F25B13/00
Filed: 1990-07-24
Abstract: PURPOSE:To permit the securing of the necessary and sufficient capacity of a room cooling side indoor unit and a room heating side indoor unit even when an outdoor unit is positioned at a higher position than the indoor unit by a method wherein the amount of refrigerant, which flows through a liquid pipe, is controlled so that the detecting result of the superheating degree of refrigerant of the room cooling side indoor unit is within a given range. CONSTITUTION:When a given time (t1) has elapsed after starting operation, a difference between the detecting values of a temperature sensor 101 and a temperature sensor 105 is detected as the superheating degree SH of refrigerant in an indoor unit C1 while a difference between the detecting values of a temperature sensor 102 and a temperature sensor 106 is detected as the superheating degree SH of another indoor unit C2. Then, the opening degree of the PMV 16 of an outdoor unit A is increased by a predetermined value (a value corresponding to several pulses) until the superheating degree SH of the refrigerant becomes a value within a given range. According to this method, the pressure of the refrigerant in a liquid pipe W is controlled so as to be substantially equal to the pressure of the refrigerant in a high-pressure side gas tube G even when the outdoor unit A is positioned at a position higher than the indoor units C1-C4 whereby the refrigerant can be distributed with a good balance to supply it to the room cooling side indoor units C1, C2 and the room heating side indoor unit C3. Accordingly, the necessary and sufficient capacities of respective units C1, C2, C3 can be ensured respectively.

Title: Hydraulic power transmission coupling
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1990-07-24
Abstract: PURPOSE:To make reduction of processing cost possible by forming a narrow groove on closely adhered or movably contacting surface of either a valve plug or a member closely adheres or movably contacts with the valve plug, and forming a flow resistance generating means with a mate member that closely adheres or movably contacts and the narrow groove. CONSTITUTION:When rotational difference occurs between a cam 1 and a rotor 5, a plunger 8 in the course of a discharge stroke is pushed to the axial direction by the cam surface 2 of the cam 1. The plunger 8 pushes out the oil in a plunger chamber 7 to an intake/discharge hole 10, the discharge port 14 of a rotary valve 11, and a communicating groove 15. The oil pushed out is supplied to an intake passage 13 by a narrow groove 17A that functions as an orifice, when the oil pressure of the discharge port 14, the communicating groove 15 and the plunger chamber 7 is raised by flow resistance, and reaction force is generated in the plunger 8 to transmit torque between the cam 1 and the rotor 5. If the cam 1 further rotates, it becomes an intake stroke, oil is sucked to the plunger chamber 7 passing through the intake passage 13, the intake port 12, and the intake/discharge hole 10, and the plunger 8 returns moving along the cam surface 2 of the cam 1.
