Title: Rotary fluid machine
Inventor: IKOMA MITSUHIRO
IPC: F01C1/348
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a rotary fluid machine with high reliability and efficiency, in which a slide load of a vane tip is reduced, even if a low-lubrication material, such as HFC-134a and HC, is used as a working medium. SOLUTION: This fluid machine is provided with a cylindrical piston 24 eccentrically disposed within a cylinder 23, and a vane 28a whose tip abuts on an inner face of the cylinder 23 so that a suction chamber 26 and a compression chamber 27 are formed, while the piston 24 and the cylinder 23 are rotated in a same rotating direction. Because the vane 28a has a projecting arc shape while the cylinder 23 has a recessed arc shape, a lubricating oil film is properly formed. Moreover, sliding speed is reduced. Accordingly, the tip of the vane 28a and the inner face of the cylinder 23 are hardly worn out so that this fluid machine has high reliability and efficiency.  Besides, because this fluid machine has a middle pressure chamber 22, sealing performance is easily secured both in a sealing part between the suction chamber 26 and the middle pressure chamber 22 and in a sealing part between the compression chamber 27 and the middle pressure chamber 22. Accordingly, pressures applied to faces of these sealing parts are reduced so that this fluid machine has high reliability and efficiency all the more.

Title: Soliton-anti-soliton conversion circuit
Inventor: YAMADA TOSHISHIGE
IPC: H01L39/22
Filed: 1985-08-07
Abstract: PURPOSE:To convert a direction of a magnetic flux without changing a direction of motion of the magnetic flux by connecting the upper electrode of the first Josephson line to the lower electrode of the second Josephson line and the lower electrode of the first Josephson line to the upper electrode of the second Josephson line respectively through a resistance or a superconductor. CONSTITUTION:When a current is input in input terminals 40 and 41 in a direction designated by real line, a counterclockwise cyclic current proceeds from a junction 42 to a junction 44. When the junction 44 becomes a voltage state, a current flows from the under part of the junction 45 to the upward. Though the junction 45 becomes a voltage state, the generated voltage is of opposite sign to that of the junction 44, so that a clockwise cyclic current is generated which proceeds from the junction 45 to the junction 46. During these steps, a direction of the magnetic flux is inverted without changing a direction of motion of the magnetic flux. If the input cyclic current is directed oppositely to that in figure, the same inversion is done. Accordingly, soliton is converted to anti-soliton or vice versa.

The heating temperature is suitable at 100 to 220 deg.C. Thereafter, the impurities 5 in the acid 9 and a small amount of undecomposed silicon compound are moved onto an analyzing base plate 13. Then, the sulfuric acid 9A on the substrate 13 is vaporized by heating means 15. The silicon compound in the acid 9A is completely decomposed, and the impurities are concentrated and solidified on the substrate 13. Eventually, the base plate 13 is analyzed using a total reflection x-ray fluorescence analyzer 17 to analyze the impurities 5.

Abstract: PURPOSE:To obtain a thermo-sensitive element of high-stability, less randomness, and high-sensitibity, by making a base of the first stage transistor for Darlington connection a common collector (semiconductor substate) or the first electrode, and making a emitter of the last stage transistor the second electrode. CONSTITUTION:Transistors 1, 2 are Darlington-connected. The constant current is flowed 5 between an emitter 20 and a common collector. And so, the thermal sensitivity of a thermosensitive element 101 increases in proportion to transistor stages. A voltmeter 6 consists of CMOS's. A system with accuracy of 1 deg.C can be obtained. A base 55 of a transistor 2 is formed at the same time with a P well of the CMOS. The base width is decepened, and current amplification ratio is equalized. The second collector is made by providing an N<+> layer 47 in addition to an emitter 46 in the base 55. The diffusion charge from the emitter is returned to the base to prevent the prestage transistor from decreasing the emitter current. A layer 57 is provided between the collector 47 and the emitter 46 to prevent surface current between the emitter 46 and the base 55 from flowing. This constitution enables a system of high reliability by multi-stage Darlington connection.

Title: Current limiting circuit
Inventor: MORIYAMA KYOICHI
IPC: H02P7/29
Filed: 1990-07-03
Abstract: PURPOSE:To prevents overheat and burning of a rotative part and automatically restarting its rotation when relieved from constraint by switching on and off an output transistor and applying and removing rotative part driving force automatically and repeatedly when the rotative part is constrained. CONSTITUTION:When a rotative part is constrained, an input signal is cut off, a transistor Q5 remains turned off, and a current source I3 continues to charge a capacitor C2. The potential of the capacitor C2 heightens further after transistors Q8 and Q11 are turned on and lowers to the base-emitter voltage of a transistor Q6 at a stretch by turning on the transistor Q5. This operation is continued until the rotative apparatus is relieved from constraint. When it is relieved from constraint in the middle of the repeated operation, a thyristor circuit is turned on for return to the normal state at that time by input of an input signal. A driving current is passed and cut off by turning on and off a control transistor to control the driving current by turning on and off the output transistor Q11 and overheat and burning of a motor coil and a driving system are prevented.
