Title: Abnormal tie detector of yarn for automatic winder
Inventor: OTOBE SEIJI
IPC: B65H63/06
Filed: 1981-08-17
Abstract: PURPOSE:To surely detect an abnormal tie of yarn, by detecting thickness of running yarn with a photoelectric detector, connecting a retrigger monostable multivibrator through a comparator and outputting an abnormal yarn-tie signal from a gate circuit through the fall-down pulse of the multivibrator and output of the comparator. CONSTITUTION:Yarn 1 with a normal tie 15 passes through a detector 4, then a comparator 6 outputs a signal H during the passing period, and a retrigger monostable multivibrator 9 operates for a time T longer than the passing period by a rise-up pulse of a differentiator 8 to output pulse at a point of rise-up and fall-down time by a differentiator 10 and inverter 11, however, an AND gate 12 is not input during the period H of the comparator 6, and cutting of a cutter 14 is not operated. On the contrary, if the yarn 1 with an abnormal tie 3 passes, the signal H from the comparator 6 is input at a point of time input with the fall-down differentiated pulse of the monostable multivibrator 9 to th AND gate 12, and output of the gate 12 operates the cutter 14 through an amplifier 13. In this way, an abnormal tie can be surely detected.

Title: Fluidized bed type heat exchanger
Inventor: OHARA TOSHIO
IPC: F28D13/00
Filed: 1988-05-25
Abstract: PURPOSE:To move fine particles in a fluidized bed, formed of spaces between the flat side surfaces of flat tubes, a first net and a second net, through suspended motion and improve heat transfer between the wall surfaces of the tubes and air by a method wherein fine particles are sealed between flat side surfaces of the flat tubers arranged in a plurality of rows in parallel and the nets for preventing the dispersion of the fine particles are provided. CONSTITUTION:When air is sent from the direction of a fan, which is shown by an arrow sign F in a diagram, the flow of the air is regulated by a first fin 2 and the speed of the air is unified. Fine particles existing on a mesh 3 are levitated upwardly simultaneously by the air and random motions are started. Comparatively high-temperature engine cooling water is introduced from the side of an engine through an introducing pipe 10 to pass through a tube 1 and effect heat exchange and, thereafter, is discharged through a discharging pipe 11 and, then, is returned to the side of the engine. Accordingly, the temperature of the engine cooling water is delivered to the tube walls and heat exchange is effected between the tube walls and air, however, the temperature boundary layer of the tube walls is collapsed by the motions of the fine particles whereby heat exchanging efficiency may be improved.

Title: Simultaneous stabilization of oscillation wavelengths of two semiconductor lasers, and device therefor
Inventor: TAKIZAWA HIDEO
IPC: H01S5/40
Filed: 1988-05-27
Abstract: PURPOSE:To seek to simultaneously stabilize the oscillation wavelengths of two semiconductor lasers in a two frequencies lengths measuring method, by using two semiconductor laser elements which oscillate lasers different in wavelength as light sources, and inputting a compound beam of each laser beam from the light sources into a measuring instrument consisting of an interferometer, and measuring displacement amounts of shifting body by the beat frequency of the compound beam. CONSTITUTION:Oscillation wavelengths of two semiconductor lasers are set, as a near infrared region, to almost equal to frequencies f1 and f2, respectively, and these compound beam is divided by a proper means and one hand is applied to a two frequencies lengths measuring instrument. For the other compound beam, the intensity of each laser beam which transmitted by wavelength fluctuation changes, with A and B points of selective characteristics of one rubidium vapor cell as the center, respectively. By receiving this light, signal voltage to show wavelength fluctuation can be obtained, whereby injection currents of a laser element are controlled and each oscillation wavelength is stabilized. Accordingly, beat frequency is also stabilized. Furthermore, a laser head can be miniaturized.

Title: Heat exchanging device
Inventor: KATAOKA KENJI
IPC: F28D15/02
Filed: 1980-09-16
Abstract: PURPOSE: To obtain a stable snow melting operation by the heat exchanging device for melting the snow accumulated on a roof by a method wherein when a temperature difference between two temperature detectors exceeds a predetermined value, the flowing direction of a heating fluid is changed.  
     CONSTITUTION: When the medium vapor temperature in a heat transmission pipe 3 becomes lower than the temperature of hot water within a pipe 1, an operating fluid within a heat transmission header 2, receiving the heat of the hot water, vaporizes and moves from one end 3a to the other end 3b due to a difference in the steam pressure to discharge heat. The fluid liquidized by this heat discharge recirculates due to the capillary action of a wick in the heat transmission pipe 3. In this instance, as the hot water temperature has a gradient in the longitudinal directon, the snow melting is likely uneven. To cope with this, temperature detectors 5 and 6 are provided at the ends of a plurality of heat transmission pipes 3. The outputs of the detectors 5 and 6 are compared by a comparator 7, and when the temperature difference exceeds the preset value, the hot water flowing direction is turned over.
