Title: Composite pipe mat apparatus equipped with snow thawing and air conditioning functions
Inventor: FUKUDA HIDEO
IPC: F24S10/75
Filed: 1983-11-08
Abstract: PURPOSE:To perform snow thawing and air conditioning by an apparatus with a single system and consequently contrive to improve the econimical efficiency and utility by a structure wherein a special composite pipe mat is employed in the apparatus, by means of one and same system of which both snow thawing and air conditioning are performed. CONSTITUTION:A composite pipe is formed by bonding a black semicircular arc heat insulating sheet (such as foamed resin sheet, glass fiber sheet or the like) 3, 3' onto the lower half portion of a transparent resin pipe (such as fiber reinforced plastic pipe or the like) 2, 2', which is inserted in a selective transmission and absorption resin film tube (such as fluoroplastic resin film tube or the like) 1, 1', which has the performance to transmit the sunlight and absorb the reflected light. A reed-screen-like unit composite pipe mat is formed by connecting several composite pipes in series through U tubes 4, 4' and joining tapes 5, 5'. During thawing, the heat of heating air is dissipated from the upper half portion of the transparent resin pipes 2, 2' in order to promote the thawing, because the lower half portions of the transparent resin pipes 2, 2' are heat-insulated by the black heat insulating sheets 3, 3' in the composite pipes. During heating, the heat collecting effect is enhanced by transmitting the sunlight through the selective transmission and absorption resin film tubes 1, 1'. During cooling, the circulation of air through the air pipe in the composite pipes prevents the interior of a room from being heated from the roof surface. In such a manner as described above, snow thawing and air conditioning functions are formed so as to be performed by an apparatus with a single system.

Title: Main shaft positioning method
Inventor: KUMAGAI AKIRA
IPC: B23Q5/20
Filed: 1989-08-10
Abstract: PURPOSE:To restrain severe changes in speed and prevent gear noise by changing a limit value corresponding to a deviation amount between a commanded stop position and a current position in positioning from a stop state to a position commanded by a stop position command. CONSTITUTION:A limit value of a limiter 6 is changed corresponding to a deviation between a target stop position and a current value. That is, a maximum limit value and a deviation limit value are given from the outside as parameters etc., and a speed command limit value for a deviation (an initial deviation amount in positioning a main shaft) to a given target value is found by a preset equation. Using this limit value causes the speed command limit value to be also changed corresponding to the deviation and not to be excessively lowered, therefore allowing severe changes in speed to be restrained against a given torget value and gear noise to be suppressed. Especially in positioning from a stop state, a torque command is once turned from positive to zero in the point that a real speed matches to the speed command limiter and then turned into negative so that no gear noise takes place.

Abstract: PURPOSE:To prevent a magnet material from jumping or damaging at superhigh speed rotation time by closely winding carbon fiber on the outer periphery of the material of a rotor. CONSTITUTION:Flanges 3a, 3b are press-fitted to both ends of a magnet material 2 made, for example, of rare earth cobalt magnet material having excellent magnetic property so as to take the weight balance of a rotor and to treat the terminal of a reinforcing system.
