A chain metal powder, which is free from branches and has a small distribution of the chain length, can be produced by a process of reducing metal ions contained in an aqueous solution, while applying a magnetic field to the solution containing ferromagnetic ions, in the presence of a polymer compound comprising repeating units of the formula (1): and repeating unit of the formula (2): or repeating unit of the formula (4); or a process which comprises the steps of reducing metal ions contained in an aqueous solution, while applying a magnetic filed to the solution, in the presence of both a reducing agent capable of generating a gas during the reduction of metal ions and a foamable water soluble compound, through the generation of a gas, a bubble layer on the surface of the aqueous solution to form a chain metal powder, separating the bubble layer formed on the surface of the aqueous solution from the solution, and collecting the chain metal powder contained in the bubble layer.

A cylindrical body arranged between a shaft body and a blade of a horizontal axis wind turbine is constituted of a cylindrical barrel portion, a first flange portion fixed to a first end of the barrel portion so that the blade is connected thereto, and a second flange portion fixed to a second end of the barrel portion and connected to the shaft body. The barrel portion is constituted of a cylindrically formed rubber stock and a plurality of filamentary bodies embedded in the rubber stock and arranged in a state inclined by a prescribed angle with respect to a direction parallel to an axial direction. When tensile force F develops in the barrel portion due to centrifugal force resulting from rotation of the blade, both opening ends of the barrel portion twistedly rotate due to actions of the filamentary bodies. Thus, it follows that the pitch angle of the blade connected to the first flange portion automatically varies with a wind speed.

A multimedia processing system of the present invention comprises an application, a multimedia abstracting unit, and a multimedia processing module. The multimedia processing abstracting unit is comprised of: a logic module; a stream path for connecting each logic module; a stream pipe for transmitting/receiving data between each logic module and the application; and a correspondence managing unit which carries structural information of the logic module, the stream pipe, and the stream path for making correspondence between with the processing module. The correspondence managing unit updates the structural information every time each logic module is created and connected according to the command from the application and, thereafter, at the point where the stream pipe and stream path are connected, receives a LOCK command indicating confirmation of structure from the application. Thereby one corresponding processing module is confirmed and started.

A sine wave electric signal whose frequency continuously varies within a predetermined frequency range is applied to a piezoelectric speaker, whereby a vibration frequency characteristic of the piezoelectric speaker is detected. A change of the frequency characteristic of the piezoelectric speaker when the piezoelectric speaker is brought into contact with concrete filled into a precast concrete form is detected based on the vibration frequency characteristic detected. With this unique feature, a filling status of concrete in the precast concrete form can exactly be detected independently of the hardness of water contained in the concrete and ambient temperature, and even if a temperature difference between air and the concrete is small.

A cutterhead is supported at the front part of a main frame so as to incline at a specified angle with respect to a vertical plane. The main frame includes (i) a roof support disposed at a position corresponding to where a reaction force acts in the direction of the periphery of a tunnel against a force caused by rotation of the cutterhead, and (ii) a pusher for pushing the roof support toward the cutterhead resisting the reaction force.

A solid ion conductive polymer electrolyte for use particularly in rechargeable batteries, capacitors and other electrochemical devices is comprised mainly of a hydroxyalkyl polysaccharide or a hydroxyalkyl polysaccharide derivative, a diester compound containing a polyoxyalkylene component, a monoester compound containing a polyoxyalkylene component and an ion conductive metallic salt.
摘要:
A recording apparatus including an apparatus body having a front section on the operator's side and a rear section remote from the operator's side, a medium feeding device supported by the apparatus body, for feeding a substantially transparent recording medium along a predetermined feed path defining a boundary between the front and rear sections, such that one of opposite surfaces of the medium faces the operator's side, a recording device disposed in the rear section of the apparatus body, for recording an image on the other surface of the medium, and a control device for controlling the recording device such that the image is laterally reversed as viewed in a first direction from the recording device toward the above-indicated other surface of the medium, with respect to a nominal desired image as viewed in a second direction from the front section toward the one surface of the medium, whereby the laterally reversed image is seen as the nominal desired image when viewed in the second direction.
摘要:
A feeding device for feeding a recording medium having a predetermined printing area on one of its opposite surfaces. The printing area extends in a printing direction. The feeding device includes a pair of feed rollers which holds the medium therebetween in rolling contact with the opposite surfaces of the medium. At least one of the pair of feed rollers is driven so as to rotate about an axis perpendicular to the printing direction, to feed the medium in the printing direction. One of the feed rollers which contacts the above-indicated one surface of the medium has an outer circumferential surface which includes a small-diameter portion whose diameter is smaller than that of the other portions. The small-diameter portion is aligned with the printing area in a direction of width of the medium perpendicular to the printing direction, so that the small-diameter portion is prevented from contacting the printed image. The feed rollers may be replaced by a platen roller of a printer. The platen roller is rotated about an axis perpendicular to the printing direction, and cooperates with a print head of the printer to hold and feed the recording medium such that the platen roller and the print head contact the opposite surfaces of the medium. This arrangement also protects the printed image from an adverse influence by a feeding action of the feeding device.

The present invention concerns a safety device for a radiator cap detachably mounted on a fluid supply opening for closing the radiator opening. The safety device comprises a lock means for preventing the opening of the radiator cap when the temperature of the coolant in the radiator is higher than a predetermined value. The lock means is provided between the radiator cap and an inner surface of the fluid supply opening. The lock means comprises a lock portion provided on an inner surface of the fluid supply opening and a lock member fixedly secured to the radiator cap. The lock member is formed of a shape memory alloy.
