摘要： PROBLEM TO BE SOLVED: To prevent the deterioration in performance of a condenser by causing the liquid drops of a liquid phase medium accumulated in an opening part at the lower end of a medium passage of the condenser to fall down effectively. SOLUTION: In a condenser cooling the steam supplied to a cooling pipe 14 connected with a cooling fin 16 to condense it to water and recovering it in a water collecting tray 21 provided in the down side of the cooling pipe 14, a needle-like member 24 is provided to face an opening part at the lower end of the cooling pipe 14, and the liquid drops accumulated in the opening part at the lower end of the cooling pipe 14 by a surface tension are collapsed by the needle-like member 24 to fall down in the water collecting tray 21. A plate-like filter can be used for the needle-like member 24. In this case, dust contained in water can be removed in addition to permitting the liquid drops to fall down from the opening part at the lower end of the cooling pipe 14 more effectively by the capillary phenomenon of the filter.

摘要： PURPOSE:To lengthen the life of a lower holder, a suspension spring and an upper holder by providing a plurality of cylinders in the holder, communicating the cylinders with each other, and interposing a member having a spherical portion between a piston head and a spring seat. CONSTITUTION:An oil damper 4 and a suspension spring 5 are interposed on the same shaft between an upper holder 2 and a lower holder 3. A plurality of cylinder chambers 2a communicating with each other are provided in a holder 2, the head 2h of a piston 2b sliding in each cylinder chamber is recessed spherically and a member 8 having a spherical portion is brought into contact with the recessed portion. In this arrangement, when diagonal force is applied to the lower holder 3, the oil damper 4 is inclined and the piston 2b at that portion is moved backward to push out oil in the cylinder chamber 2a. While the pushed-out oil passes through a communicating rube 2c to advance the piston 2b having small working force, a slippage is caused between the member 8 and the head 2h to change the working direction.

摘要： PROBLEM TO BE SOLVED: To reduce wave drag by a method wherein a fluid element, such as an engine nacelle, is arranged in a given position on the upper surface of a main wing, an air flow generated by the fluid element is positively overlapped with an air flow on the upper surface of the main wing to form gentle pressure distribution on the upper surface of a main wing, and the generation of an impact wave is delayed. SOLUTION: An engine nacelle is arranged on the upper surface of a main wing, and when the position in a longitudinal direction of the front end of the engine nacelle is set (b, i) to a range of 63-100% from the front end of the chord of the main wing, in a transonic speed region, the generation of an impact wave on the upper surface of a main wing and the increase of a drag are suppressed. As the increase of a fuel consumption amount is prevented, a cruising speed is increased. When the front end of the engine nacelle is positioned (e) in front from the 63% position of the chord, an effect to suppress an impact wave is not provided and drag is increased.

摘要： PURPOSE:To simplify structure by forming driving source of a linear motor, and providing numerous magnetic pole pieces disposed on the output shaft of the linear motor as well as numerous coils fixed opposedly to the periphery of the magnetic pole pieces and excited sequentially with the specified phase difference. CONSTITUTION:When the state of front wheels being about to be locked is detected by a wheel speed sensor 53, load is dispatched to a linear motor 10 from a battery 48 by the command of an electronic control device 52, so that the output shaft 27 of the linear motor 10 is driven to the right against the spring force of a return spring 32, and an expander piston 27a recedes. A cutoff valve 17 is thereby closed, and braking oil pressure is decreased. When the driving speed of the shaft 27 requested at this time is large, a selecting circuit 47 performs load dispatching to all coils 391-393, 401-403, 411-413 in a first group G1 - a third group G3, and as the request driving speed becomes smaller, the number of load dispatched groups is reduced into two or even one.

摘要： PURPOSE:To effectively cool a high temperature portion without a cooling medium in a simple structure by operating a thermal electric power generating element installed on the high temperature portion of an internal combustion engine according to a control signal from a control device. CONSTITUTION:A ring-shaped thermal electric power generating element 18 for cooling an intake pipe 11 is installed on the outer periphery on the intake port 7 side of the intake pipe 11. The outer periphery of a cylinder 2 is covered with a cylindrical thermal electric power generating element 20 formed by the same material as the thermal generating element 18. In this arrangement, when the thermal electric power generating element 18 is operated by a control device 16 at the time of long time low speed running at high outside air temperature, heat energy absorbed from the intake pipe 11 is converted into electric energy, whereby the intake pipe 11 is positively cooled. Cooling for the cylinder 2 is performed by operating the thermal electric power generating element 20 by a control device 16. Accordingly, an internal combustion engine E can be cooled without a cooling medium such as cooling water, cooling air or the like.

摘要： PURPOSE: To facilitate braking, whether a vehicle turns rightward or leftward, by pivoting a pair of right and left brake pedals, each of which can singly operate a rear wheel brake, to a vehicle body while bringing the pedals close to right and left steps. CONSTITUTION: A driver can normally control a rear wheel brake 20r by using either the right or left foot resting on steps 8, 8' to operate the corresponding brake pedal 9 or 9'. Therefore, single-footed ground touch and rear wheel brake control can be performed easily at the same time even during a turn in either the right or left direction.

摘要： PURPOSE:To prevent overrotation of an engine by maintaining the speed change ratio at the change ratio immediately before the speed change, or controlling it at the change ratio responding to the assumed actual car speed at the time when a sudden deceleration is released, when the rear wheel is suddenly decelerated compared to the actual speed, in the speed change control of a motorcycle in a rough terrain running. CONSTITUTION:In a hydraulic continuously variable transmission TM, a constant injection type hydraulic pump P and a variable capacity type hydraulic motor M are connected each other to composed a hydraulic closed circuit 21. The hydraulic pump P is connected to an input shaft 3 which is driven by an engine E, and the hydraulic motor M is connected to a rear wheel Wr through an output shaft 2 and a chain 14. In this case, a throttle opening sensor Sa, an engine rotation frequency sensor Sb, and a car speed sensor Se are connected to a control device C, which controls the operation of an actuator 28 while reading input signals of these sensors. Therefore, when the rear wheel Wr is decelerated suddenly compared to the actual car speed, the speed of the rear wheel is maintained at the speed change ratio immediately before the speed change, or controlled at the speed change ratio responding to the assumed actual car speed at the time when the sudden deceleration is released.

摘要： PROBLEM TO BE SOLVED: To prevent a liquid-phase working medium, which is retained on a radially inner side of a sealing member for sealing sliding surfaces between a side surface of a rotor and a casing of a rotary fluid machine, from flowing into a vane chamber in an intake stroke. SOLUTION: The rotary fluid machine comprises a rotor chamber, a rotor, a vane 48 supported in a freely protruding/retreating manner to the rotor, a piston 47 slidably engaged with a cylinder 44, and a ring seal 79 for sealing the side surface of the rotor. Even in the case where a high-pressure water, supporting the vane 48 in a floating state is retained in an annular groove 74 of the casing 11, the water is exhausted into a low-pressure vane chamber in an exhaust stroke, via water exhaust passages 11a, 11b formed in the casing 11 and a water exhaust passage 79c formed in the ring seal 79. Then the water is exhausted therefrom into an exhaust port 91. Thus, it never happens that the water is exhausted into the vane chamber in the intake stroke to cool vapor.
