摘要:
Fine coal particles are recovered from a slurry of finely divided coal by mixing coarsely divided coal and a binder together to cause the binder to adhere to the surfaces of the coarsely divided coal pieces, mixing the slurry with the coal pieces having the binder adhered thereto to cause fine coal particles to adhere to the binder over the surfaces of the coal pieces serving as nuclei and thereby form agglomerates, and separating the agglomerates from the remaining slurry portion to recover the fine coal particles along with the coarsely divided coal and the binder.

It is intended to provide a three-dimensional scaffolds appropriate for culturing animal cells such as chondrocytes and fibroblasts. These three-dimensional scaffolds which comprise a chitosan/acidic biopolymers hybrid fibers composed of chitosan or its salts in the inside of the fiber and complexes of chitosan with biodegradable acidic biopolymers coating the fiber surface, are made of fibers capable of retaining their shapes after allowing to stand Dulbecco's modified Eagle's medium (DMEM) containing 10% of FBS (fetal bovine serum) at room temperature for 2 weeks.

Nb, Sn, In, Al and Zn, is formed by a dry method on a synthetic resin substrate having hydrophobicity, and a method for its production.
摘要:
A portable trimmer in which the power generated by an internal combustion engine is transmitted to a cutter via a centrifugal clutch and the output power of the internal combustion engine is controlled by operating a manual throttle lever, thereby adjusting the throttle opening of a throttle valve via a throttle wire. The portable trimmer includes a friction member arranged to face the clutch drum of the centrifugal clutch, a moving member which is connected to the friction member and moves the friction member between a braking position where the friction member is pressed against the clutch drum and a non-braking position where the friction member is kept away from the clutch drum so as to release the braking, a manual release device for moving the moving member from the braking position to the non-braking position, and a release restricting device for controlling the behavior of the manual release device.
摘要:
A surface-treated PFA film, wherein hydroxyl groups and carbonyl groups are present on the surface of the surface-treated PFA film. Further, the surface state of the surface-treated surface is a surface state having no irregularities, and preferably the average surface roughness is at most 10 nm. The surface treatment is carried out by RF or DC bombardment method, preferably in an Ar gas atmosphere.
摘要:
A granulating apparatus comprising a stirring tank or a duct for containing a slurry of particulate to granular coal having a binder incorporated therein, a rotary shaft disposed in the tank or duct and at least one agitating blade made of metal netting and attached to the rotary shaft.
摘要:
A process for removing ash from coal comprising the steps of pulverizing the coal to fine particles, admixing water with the finely divided coal to prepare an ash-containing slurry of finely divided coal, mixing with the slurry an oil and seeds in the form of oleophilic solid grains and serving as granulating nuclei to granulate the finely divided coal, separating the resulting granules from the mixture and washing the granules with water to remove the ash, and disintegrating the washed granules to obtain a deashed coal and recover the seeds for reuse.

A plant cultivation method of the present invention includes the steps of: placing a plant under a condition at a pressure of not less than 1.5 atmospheres and not more than 10 atmospheres; and cultivating the plant. A plant cultivation device (1) includes: a cultivation chamber (10); and a compressor (20) which supplies compressed air into the cultivation chamber. A carry-in opening (30), which is provided on a side wall (16) of the cultivation chamber (10) so that a material is carried in/out to/from the cultivation chamber (10) via the carry-in opening (30), is provided with a cover (31) which has a shape that is hemispherical and protrudes toward an inside of the cultivation chamber (10). The cover (31) closes the carry-in opening (30) by being in contact, via a packing (32), with an inner surface of the side wall (16) surrounding the carry-in opening (30). The cultivation chamber (10) has an internal pressure higher than an atmospheric pressure by causing the compressor (20) to supply compressed air into the cultivation chamber (10) in a state in which the carry-in opening (30) is closed. A plant growth rate is improved by cultivating a plant in a high pressure environment which is different from a natural environment. A plant cultivation device is provided for achieving plant cultivation in a high pressure environment.

There is provided a traffic sign apparatus that can improve the luminance of a sign surface which emits light by ultraviolet irradiation, and the uniformity ratio of illuminance, so as to enhance the visibility thereof in the nighttime. The traffic sign apparatus 10 includes a sign body 11 having the sign surface 14 which emits light by ultraviolet irradiation, and an irradiation device 12 for irradiating ultraviolet rays onto the sign surface 14. Assuming that the maximum incident angle of the ultraviolet rays be θ1, the ultraviolet rays being irradiated from the ultraviolet emission lamps 26 of the irradiation unit 12 onto the objective sign surfaces W1 and W2 on the sign surface 14 which is the irradiation object of the ultraviolet emission lamps 26; and that the minimum incident angle be θ2, the angle θ1 is set to more than 30° and less than 70°; and the angle θ 2 is set to more than 5° and less than 30°.
摘要:
Disclosed is a torsion beam type rear suspension which comprises a pair of right and left trailing arms (2), a torsion beam (3), and a spring seat (6) disposed in a corner region defined at a junction between each of the lateral ends of the torsion beam and a rear portion (2c) of a corresponding one of the trailing arms to form a mounting seat for a coil spring (8). A vertical flange (13) is formed along a laterally inner edge (12) of the spring seat to have a longitudinally front edge extending vertically along a rear side surface of the torsion beam. The spring seat has a first region (7b) of disposed opposed to the corresponding trailing arm and fixed thereto approximately in its entirety, and a second region (16) disposed opposed to the torsion beam and fixed thereto only through the vertical flange. The torsion beam type rear suspension of the present invention can improve the supporting rigidity of the spring seat relative to a coil spring without increasing the rigidities of the spring seat and trailing arm themselves, while allowing the risk of stress concentration occurring at an end of the torsion beam to be reduced, so as to achieve increased chassis rigidity and adequately maintain suspension functions.
