Title: Accumulator
Inventor: KUSHIRO KAN
IPC: F25B43/00
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain a mixture of gas-phase refrigerant and liquid-phase refrigerant having a stabilized mixing ratio from a discharge pipe by fixing a liquefaction member to the forward end of a liquid refrigerant introduction pipe. SOLUTION: When an compressor is operated during operation (cooling state) of an air conditioning system, a liquid-phase refrigerant is fed to an indoor unit under two layer state where liquid-phase and gas-phase are mixed. The refrigerant is vaporized through heat exchange with heat in a room and returned back to an accumulator 22 through an introduction pipe 42. The refrigerant is passed through a liquefaction member, i.e., a mesh 50, provided at the forward end of the introduction pipe 42 and drips, in liquid-phase state, onto the liquid surface 50. Consequently, only gas-phase state refrigerant 15 sucked into a discharge pipe 44 from the forward end 46 thereof and fed to a compressor while keeping a constant mixture state with liquid refrigerant fed into the discharge pipe 44 from a metacenter 48.

Title: Fiber raman amplifier and optical fiber communication system using same
Inventor: MASUDA KOJI
IPC: H04B10/29
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain a Raman amplifier whose Raman gain does not vary timewise and whose gain spectrum exhibits a satisfactory controllability. SOLUTION: Exciting light is generated by driving a laser diode 2a with a current wherein an alternating current is superimposed upon a direct current, and a multiplexer 3 causes the generated exciting light incident on an optical fiber 1 together with signal light to optically excite the fiber 1, whereby the signal light is Raman-amplified. Thus, the oscillation wavelength spectrum of the diode 2a is stabilized at multimode oscillation. Further, variations in Raman gain are suppressed by setting the frequency of the AC current to a value much higher than the frequency response cut-off frequency of the Raman gain, whereby the wavelength spectrum characteristics of the Raman gain can be stabilized.

Title: Encoding system for date transmission
Inventor: EBIHARA SEIJI
IPC: H03M5/10
Filed: 1977-11-17
Abstract: PURPOSE: To increase the base band transmission enable distance for the wire transmission line by setting the transmission data to the fixed code in the nonsynchronous system to secure the 1/n demodulation data distortion.  
     CONSTITUTION: Signal C is obtained by sampling and holding transmission data B through D-FF1 which is driven by sampling pulse A; logical sum signal H of signal C and data B is obtained; and furthermore signal I is obtained by sampling and holding signal H through D-FF9 which is driven by sampling pulse inversion A. Then transmission code D is decided by the logical product of signal I and inverse signal I. On the other hand, pattern generator circuit 10 produces the hihg-speed repetition code of "0" and "1" based on pulse A, and the repetition code is always started from "0" after reset of signal I. Thus, "0" of data B is converted to the high- speed repetition code of "01" with the reset of signal I used as the changing poing from "1" to "0". As a result, the data distortion of +/n can be obtained.

In the equation II, DELTAZi is the displacement quantity of the aspherical surface at height phii1 from the optical axis on the incidence side of an (i)th lens and phii1=L/3; and DELTAZi2 is the displacement quantity of the aspherical surface at height phii2 from the optical axis on the incidence side of the (i)th lens and phii2=L/3. Consequently, the curvature of field is compensated in a main scanning plane and a subscanning plane.
