Title: Manufacture of frictional material
Inventor: SUGITA YASUSABUROU
IPC: C09K3/14
Filed: 1980-08-29
Abstract: PURPOSE: To obtain the frictional material into which the desired amount of a metallic piece is mixed uniformly by manufacturing the frictional material by using raw paper made by a blank for the frictional material containing metallic foil powder.  
     CONSTITUTION: When heatproof fibers for the frictional material, a frectional performance regulating agent, binder resin etc. are beaten and disintegrated, the metallic foil powder, thickness thereof is perferably 30μ or lower, is mixed. The mixture is introduced into a water tank, a rubber emulsion, vitriolic alumina, a surface active agent, etc. are mixed, and paper is made. The mixture does not precipitate suddenly in the water tank because the metallic foil powder is used as metals. And when the water tank is agitated when making paper, the metallic foil powder floats and is mixed excellently into the raw paper for the frictional material, and paper can be made under a condition that the desired amount of the metallic foil powder is mixed uniformly. The raw paper made for the frictional material is pressed to remove moisture, dried, sliced in fixed width, wound spirally, heated, pressed and shaped, thermally treated, and ground and a product is obtained.

Filed: 1992-04-14
Abstract: PURPOSE:To measure composition of amount of fish shoals for each fish type by detecting a Doppler frequency of a reception signal and then preparing a histogram of reception signal strength for each Doppler frequency by calculation. CONSTITUTION:A reflected ultrasonic wave is received 2 and is converted to electrical signal, is amplified using an ultrasonic reception circuit 3, and then is fed to a detection circuit 4 and a Doppler detection circuit 5. The circuit 4 outputs an envelope signal which is proportional to the reflection strength of a fish shoal to a signal synthesis circuit 6. The circuit 5 detects the traveling speed of each fish shoal and then discriminates fish type according to the traveling speed. The circuit 6 synthesizes an envelope state A and a Doppler frequency information B from the circuit 5 by time-sharing. The output signal from the circuit 6 is fed to a signal separation circuit 8 through a transmission line 7. The circuit 8 separates information A from information B and then output to a histogram operation circuit 9 and a display 10. The circuit 9 calculates and prepares strength histogram of envelope for each Doppler frequency. The fish shoal amount composition for each fish type is obtained by obtaining the frequency of envelope amplitude for each Doppler frequency.

Title: Vertical type earth heat pump
Inventor: YAMAMOTO TOMOYUKI
IPC: F25B30/06
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To enable takeout of heat in the ground with high efficiency by constructing an underground heat exchanger out of a pipeline of forward and backward lines stretching in the vertical direction in the ground and by disposing a heating mechanism on the evaporated refrigerant outlet side of the heat exchanger. SOLUTION: In heating, a refrigerant flows along the route of a pipeline shown by a thick line and heat is taken out from a ground-side heat exchanger 18. In other words, the refrigerant flows on the check valve 34 side and, therefore, an expansion mechanism 30 is bypassed. At this time, the refrigerant of high temperature flows through a heating mechanism 24 constructed by branching an outlet piping from a compressor 16 and joins the flow on the outlet side (5) of an underground heat exchanger 12. Therefore the amount of heat transfer increases and efficiency is enhanced. At the time of cooling, the refrigerant flows along the route of the pipeline shown by the thick line and heat is absorbed from the ground-side heat exchanger 18. In other words, a check valve 34 checks the flow and the expansion mechanism 30 operates as a pressure reducing valve.  At this time, the flow is checked in the heating mechanism 24 constructed by branching the outlet pipeline from the compressor 16, by the operation of a valve 32.
