Filed: 1979-07-10
Abstract: PURPOSE: To enable the high speed spinning of a high strength optical fiber by forming a tin oxide coat on the surface of an optical fiber with high reactivity immediately after spinning and further covering the fiber with a metal.  
     CONSTITUTION: SiO 2 -contg. fiber base material 1 is attached to base material feed mechanism 2, fed to heating furnace 3, melted, and spun into fiber 4 through a spinning hole. A tin oxide coat is formed on hot fiber 4 of 300W500°C immediately after the spinning in reaction tube 5 in an oxidizing atmosphere such as air. The coat is formed by dissolving an org. tin compound such as methyltin tribromide, methyltin trichloride or ethyltin trichloride in an org. solvent and coating the soln. A metal such as Sn, Pb, Cu, Ni or Mn is then covered by hot dipping, vapor deposition or other method with metal covering device 6. The covered fiber is cooled with cooler 7 and coiled around drum 8.

Abstract: PURPOSE: To improve the thermal transmission efficiency of the heat exchanger for an air conditioner, by integrally arranging first capillary tubes, collection tubes and second capillary tubes onto each thin thermal transmission face member, and making the transmission face members into a lattice or zigzag form and arranging them side by side.  
     CONSTITUTION: A condensed refrigerant is distributed from a header 10 into each of the capillary tubes 11 formed onto each thin thermal transmission face member 16 to be expanded, therefore its pressure is reduced, and it is transformed into a two-phased (liquid-gas) stream having a low temperature and low pressure. Then the refrigerant is passed through each collection tube 12 to a plurality of the second capillary tubes 13, where it is heat-exchanged with a fluid to be heat-exchanged and evaporated, and then is collected in a header 14. In this case, the fluid to be heat-exchanged passes through the heat exchanger while heat-exchanging with the thin thermal transmission face members 16 and fins 18 to effect cooling. Thus in the present heat exchanger, the first capillary tubes are provided as a multi-pass, each pass has a lattice of second capillary tubes, and therefore the distribution properties of the heat exchange fluid can be improved to improve the heat exchange efficiency.

Title: Printer paper feed mechanism
Inventor: MURAKAMI KENJIRO
IPC: B41J11/42
Filed: 1988-04-08
Abstract: PURPOSE:To make possible paper feed with high accuracy from the head position of continuous paper without any adverse effects on the feed accuracy of cut form by allowing the pressing force of the first paper feed means to be variable in three steps and applying a stronger pressing force to the cut form than to the continuous paper. CONSTITUTION:The first paper feed means 20 is provided between a sprocket means for feeding continuous paper and a printing head 1, and the second paper feed means 22 is arranged on the downstream side of the printing head 1. Then this paper for continuous slip is fed under pressure by the first paper feed means 20 until the paper for continuous slip is engaged with the second paper feed means 22. After this engagement, the paper for continuous paper is fed by the second paper feed means 22 in a state where the pressing force of the first paper feed means 20 is cancelled. Next, when the cut form is used, a stronger pressing force is applied by the first paper feed means 20 than when the continuous paper is employed, and the cut form is fed under pressure. Consequently, the feed accuracy of the paper for continuous slip can be improved and dots can be formed with high accuracy on paper, starting with the first line.

Title: Brushless dc motor
Inventor: GOTOU MAKOTO
IPC: H02P6/28
Filed: 1981-06-08
Abstract: PURPOSE:To provide a brushless DC motor which can prevent the withstand voltage breakdown and the thermal breakdown of a drive transistor by slowly reducing the timing of a coil supplying current at the time of stopping an energization, thereby reducing a spike-shaped voltage. CONSTITUTION:When a zero voltage signal is applied as a stop signal from VCC to the terminal 48 of an energization stopping circuit 49, a transistor 42 is turned OFF, a capacitor 44 is charged from zero voltage to higher voltage. When the terminal voltage C of the condenser becomes higher than a forward voltage VBE between the base and the emitter, a transistor 46 is activated. As the voltage C rises, the emitter current of the transistor 46 will slowly increase, part of the differential current (i1-i2) corresponding to the command voltage A is absorbed by the transistor 46, thereby gradually decreasing the current to a resistor 13. As a result, the current supplied to a motor coil slowly decreases in time sequence. When the voltage C becomes up to 2VBE, a transistor 47 is conducted, thereby absorbing the current (i1-i2) completely and stopping the energization to the motor coil.

Title: Pattern verifying system
Inventor: SUZUKI KATSUKI
IPC: G06F17/50
Filed: 1989-04-10
Abstract: PURPOSE:To simplify a processing regardless of the branch configuration of a pattern and the number of patterns by performing pattern erasure by deciding the number of patterns neighboring to the pattern divided at a branch point, and performing the detection of a loop pattern based on the presence/absence of a remaining pattern. CONSTITUTION:All the remarked patterns are registered on a table after dividing at the branch points, and the number of branch at the endpoint of the pattern is registered in table arrangement, and next, the number of branch of the table is updated after erasing the pattern having the number of branch of one from the table. The pattern having the number of branch of one is erased from an updated result similarly, and such operation is repeated until no pattern having the number of branch of one exists or no data exists. And it is judged that no loop pattern exists when no data exists in the table, and that the loop pattern is formed with a data pattern when the data remains, and the data is displayed. Thereby, it is possible to detect all the loop patterns thoroughly regardless of the configuration of the pattern and the number of patterns, which simplifies the processing.

Abstract: PURPOSE: To improve dewatering efficiency without addition of a flocculant, by washing sludge, generated during anaerobically digesting treatment, with water, reforming the sludge by addition of mineral acid, and then dewatering the reformed sludge.  
     CONSTITUTION: Anaerobic sludge is fed into a water-washing vessel 1, where the anaerobically-digested sludge is washed with clarified water or discharged water from a sewage-purifying plant by adding 2W5pts.vol. of the washing water to 1pt.vol. of the sludge. By letting the sludge flow through the vessel 1, coagulation-inhibiting substance contained in the sludge is washed away. The sludge washed and precipitated in the water-washing vessel 1 is fed into an acidifying vessel 3 by a sludge pump 2. In the acidifying vessel 3, the sludge fed from the water-washing vessel 1 is adjusted at pH 1W4 by addition of mineral acid. Under said pH condition, the sludge turns into dense particles. The treated sludge is then fed to a dewatering step.
