Title: Device for protecting torque transmission of guide vane
Inventor: KUROSAWA SADAO
IPC: F03B3/18
Filed: 1988-05-26
Abstract: PURPOSE:To prevent torsional breakage of a guide vane shaft by supplying pressure oil to a friction device coupling the shaft to the lever of guide vane when abnormal torsional stress is generated at the shaft so as to decrease the frictional engagement force. CONSTITUTION:A detector 25 detects torsional stress at a shaft 5 of guide vane 1 supported rotatably between upper and lower covers 2, 3. This time, when a detection signal is abnormal, an electrically-driven hydraulic pump 22 is controlled by a controller 23 to operate a hydraulic cylinder 20 resulting in descending of a piston 20a. Pressure oil is introduced in a gap 24b between upper and lower taperings 16a, 16b in a friction device 6 connecting a shaft 5 and a lever 7. Consequently, the upper and lower taperings 16a, 16b are spaced each other to weaken frictional engagement force of an inner race friction- engaging with the shaft with an outer race 18 friction-engaging with the lever 7. It is thus possible to surely prevent the torsional breakage of shaft.

Title: Screw drum-shaped reservoir elector
Inventor: OKABE YOUNOSUKE
IPC: B65G33/12
Filed: 1980-09-18
Abstract: PURPOSE: To prevent occurrence of stink, etc. due to adhesion of refuse in such a way that a reservoir, etc. are used at the end of a dust chute in a building or another, spiral protruded portions are provided around the inner circumferential surfaces in order to promote self-cleaning action.  
     CONSTITUTION: Refuse is reserved by means of sliding down from a dust chute 1 into a drum 4. The refuse is fed to an expelling end 14 by means of revolution of the drum 4 to cause feeding action to a spiral stepped part 6. Then, since the working faces 8 have always action to push refuse in the ejecting direction, they revolve relatively to refuse, and offer self-cleaning action. Besides, since truncate conical faces 7 also make action to feed refuse, they offer self-cleaning action likewise. In addition, since sectional area of the drum is reduced per pitch of the helicoid due to existance of the spiral stepped part 6, compressive ejecting effect can be improved.

Abstract: PURPOSE:To easily product a high-quality molding of a desired shape by a method in which a straight shape of a core metal made of a shape-memory alloy is covered on a molding uniformly, and the core metal is deformed into a memory shape at the same time as molding is made by heating and then pulled out. CONSTITUTION:A shape-memory alloy (e.g., Ni-Ti, etc.) is deformed into a given shape, put in a high-temperature furnace, and heated at about 500 deg.C for about 20min to memorize a given shape in it. The bent core metal 20 is tensed into a straight form by using a corrector 8 to obtain a straight core metal 21. The core metal 21 is inserted into an extruder and a primary molding 22 covered with an unvulcanized rubber is obtained. The primary molding 22 is cut into a given size by a cutter 2 and then held at 150 deg.C for 15-20min in a vulcanizing machine 5. When the temperature of the core metal 21 reaches 100 deg.C, for example, the shape is restored to obtain a shape similar to that of a final molding covered with an unvulcanized rubber having a desirably bent portion. At a time when 150 deg.C is reached thereafter, the molding is vulcanized to obtain a core- inserted molding 24, and the core metal 20 is then taken out of the molding 24 to obtain a tubular hose 25 with a bend portion as a final product.

Title: Direct current power unit for ic testing device
Inventor: KUTSUNO TAKAO
IPC: G01R31/26
Filed: 1988-05-30
Abstract: PURPOSE:To eliminate the need for a D/A converter for output voltage adjustment by detecting the difference between a DC voltage to be applied to an IC to be tested and a specific standard voltage corresponding to the voltage, generating and storing correcting data based upon the difference in advance. CONSTITUTION:A D/A converter 12 generates an output voltage V0 according to digital data supplied from a control part 27. The voltage V0 is made into a DC output voltage Vop through an amplifier 25 and a current detecting circuit 26 and applied to the IC to be tested. Prior to a test, a corrector 30 detects the difference Vde between the voltage Vop and the specific standard voltage to be applied to the IC and the difference is A/D-converted 35 and stored on a memory 15 through a switch circuit 14. When the test is conducted, the correction data is read out of the memory 15 through the circuit 14 according to the digital data and D/A-converted 13 into a correcting voltage Vh, which is inputted to the amplifier 25 additively together with the voltage V0. Thus, while the voltage Vop which is corrected into the specific DC voltage to be applied to the IC is applied to the power input pin of the IC, the power consumption is measured.

IPC: F16F9/46
Filed: 1990-05-22
Abstract: PURPOSE: To bring about preselectable, advantageously medium damping action in the event of a defect by providing a second throttle passage which is opened during defects. CONSTITUTION: While an electromagnetic coil 32 is current-loaded, a control slider 34 moves against a return spring 36 and a slit 96 provided in the passage 91 of a second throttle passage 80 is completely covered with the edge 97 of a valve element 44, so that in a predetermined driving condition of a damper 2 the passage 90 is completely closed and ceases to function, with a predetermined medium flowing through only a throttle passage 30 having a variable throttle cross section. However, if the electromagnetic coil 32 is not loaded with nor acted upon by current because of a defect, then the return force of the spring 36 pushes a control slide 34 toward the stepped part 88 of the valve element 44 to close the passage 30 by a predetermined amount or more and at the same time to open the passage 90.  The throttled condition of the pressure medium flowing through the passage 90 is specified by an effective throttle surface 98, which is designed to effect an arbitrarily selectable, advantageously average damping.
